   OPINION

JUSTICE TODD

, It is a core principle of our republican form of government “that the. voters should choose their representatives, not the other way around.” In this case, Petitioners allege that the Pennsylvania Congressional Redistricting Act of 2011 (the “2011 Plan”) does the latter, infringing upon that most central of democratic rights — the right to vote. Specifically, they contend that the 2011 Plan is an unconstitutional partisan gerrymander. While federal courts have, to date, been unable to settle on a workable standard' by which to assess such claims under the federal Constitution, we find no such barriers under our great Pennsylvania charter. The .people of this Commonwealth should never lose sight of the fact that, in its protection of essential rights, our founding document is the ancestor, not the offspring, of the federal Constitution, We conclude that, in this matter, it provides a constitutional standard, and remedy, even if the federal charter does not. Specifically, we hold that the 2011 Plan violates Article I, Section 5 — -the Free and Equal Elections Clause— of the Pennsylvania Constitution.

The challenge herein was brought in June 2017 by Petitioners, the League of Women Voters and 18 voters — all registered Democrats, one from each of our state’s congressional districts — against Governor . Thomas W. Wolf, Lieutenant Governor Michael J. Stack, III, Secretary Robert Torres, and Commissioner Jonathan M. Marks (collectively, “Executive Respondents”), and the General Assembly, Senate President Pro Tempore Joseph B. Scarnati, III, and House Speaker Michael C. Turzai (collectively, “Legislative Respondents”). Petitioners alleged that the 20Í1 Plan violated .several provisions of our state Constitution.

. On January 22, 2018, this Court entered a per curiam order agreeing with Petitioners, and deeming the 2011 Plan to “clearly, plainly and palpably violate[]” our state Constitution, and so enjoined its further use. See Order, 1/22/18. We further provided .that, if the' General Assembly and the Governor did not enact a remedial plan by February 15, 2018, this Court would choose a remedial plan. For those endeavors, we set forth the criteria to be applied in measuring the constitutionality of any remedial plan, holding that:

any congressional districting plan shall consist of: congressional districts composed of compact and contiguous territory; as nearly equal in population as practicable; and which do not divide any county, city, incorporated town, borough, township, or ward, except where necessary to ensure equality of population.

Order, 1/22/18, ¶ “Fourth.” Our Order indicated that an opinion would follow. This is that Opinion, and we emphasize that, while explicating our rationale, nothing in this Opinion is intended to conflict with, or in any way alter, the mandate set forth in our Order of January 22, 2018.

I. Background

A. Redistricting Mandate

Article I, Section 2 of the United States Constitution requires that a census be taken every 10 years for the purpose of apportioning the United States House of Representatives. Following the 2010 federal census, Pennsylvania’s share in the House was reduced from 19 to 18 members. As a result, the Commonwealth was required to redraw its congressional district map.

Pennsylvania’s congressional districts are drawn by the state legislature as a regular statute, subject to veto by the Governor. While this process is dictated by federal law, it is delegated to the states. The federal Constitution’s Elections Clause provides that “[t]he Times, Places and Manner of holding Elections for Senators and Representatives, shall be prescribed in each State by the Legislature thereof,” unless Congress should “make or alter such Regulations.” U.S. Const, art. I, § 4, cl. 1. Pursuant to the Elections Clause, Congress passed 2 U.S.C. § 2a, which provides that, following the decennial census and reapportionment, the Clerk of the House of Representatives shall “send to the executive of each State a certificate of the number of Representatives to which such State is entitled” and the state shall be redistricted “in the manner provided by the law thereof.” 2 U.S.C. § 2a. If the state does not do so, Representatives are to be elected as further provided in Section 2a.

B. Plan Passage

The 2011 Plan, Senate Bill 1249, was enacted on December 22, 2011, setting forth Pennsylvania’s 18 congressional districts. In the November 2010 general election, voters elected Republicans to majorities in both houses of the General Assembly and elected a Republican, Tom Corbett, as Governor. Thus, in 2011, the Republican-led General Assembly was tasked with reconstituting Pennsylvania’s congressional districts, reducing their number by one, and adjusting their borders in light of population changes reflected by the 2010 Census. On May 11, June 9, and June 14, 2011, the Pennsylvania House and Senate State Government Committees held hearings on the subject of redistricting, for the ostensible purpose of receiving testimony and public comment on the subject of redistricting generally. On September 14, 2011, Senate Bill 1249, Printer’s Number 1520, principally sponsored by the Republican leadership, was introduced, but contained absolutely no information concerning the boundaries of any congressional districts. On December 7, 2011, the bill was brought up for first consideration, and, on December 11, 2011, for second consideration.

Thereafter, the bill was referred to the Senate State Government Committee, where, on December 14, 2011, it was amended and reprinted as Senate Bill 1249, Printer’s Number 1862, now providing proposed boundaries for each of Pennsylvania’s 18 congressional districts, before being reported out of committee. The same day, the bill was referred to the Senate Appropriations Committee, where it was again amended and reprinted as Senate Bill 1249, Printer’s Number 1869, and reported out of committee to the floor. There, Democratic Senator Jay Cos-ta introduced an amendment to the bill he indicated would modify it to create 8 Republican-favorable districts, 4 Democrat-favorable districts, and 6 swing districts, but the Senate declined to adopt the amendment and passed Senate Bill 1249, Printer’s Number 1869, in a 26-24 vote, with all Democrats voting against passage. The same day, Senate Bill 1249, Printer’s Number 1869, proceeded to the House of Representatives, where it was referred to the House State Government Committee,' and reported out of committee. The next day, on December 15, 2011, Senate Bill 1249, Printer’s Number 1869, was brought up for first consideration, and, on December 19, 2011, second consideration. On December 20, 2011, the bill was referred to the House Appropriations Committee, re-' ported out of the committee, and passed in. a 136-61 vote, with 36 Democrats voting in favor of passage, On December 22, 2011, Senate Bill 1249, Printer’s Number 1869, proceeded to the governor’s desk where then-Governor Corbett signed, it into law as Act 131 of 2011, the 2011 Plan.

2. Other Characteristics

Of the 67 counties in Pennsylvania, the 2011 Plan divides a total of 28 counties between at least two different congressional districts: Montgomery County is divided among five congressional districts; Berks and Westmoreland Counties are each divided among four congressional districts; Allegheny, Chester, and Philadelphia Counties are each divided among three congressional districts; and Cambria, Carbon, Clarion, 'Crawford, Cumberland, Delaware, Erie, Greene,. Huntingdon, Lackawanna, Lancaster, Lawrence, Lebanon, Luzerne, Monroe, Northampton, Northumberland, Perry, Somerset, Tioga, and Washington Counties -áre each split between two congressional districts. Additionally, whereas, prior to 1992, no municipalities in Pennsylvania were divided among multiple congressional districts, the 2011 Plan divides 68, or 2.66%, of Pennsylvania’s municipalities between at least two Congressional districts.

Finally, as noted above, the General Assembly was tasked with reducing the number of Pennsylvania’s congressional districts from 19 to 18, necessitating the placement of at least two congressional incumbents into the same district. The 2011 Plan placed then-Democratic Congressman for the 12th Congressional District Mark Critz and then-Democratic Congressman for the 4th Congressional District Jason Altmire into the same district. Notably, the two faced off in an ensuing primary election, in which Critz prevailed. He subsequently lost the general election to now-Congressman Keith Rothfus, who has prevailed in each biannual election thereafter.

D. Electoral History

As grounding for the parties’ claims and evidentiary presentations, we briefly review the Commonwealth’s electoral history before and after the 2011 Plan was enacted. As noted above, the map for the 2011 Plan is attached at Appendix A. The parties have provided copies of prior congressional district maps — for 1943, 1951, 1962, 1972, 1982, 1992, and 2002 — -which were procured from the Pennsylvania Manual. They are attached as Joint Exhibit 26 to the Joint Stipulations of Fact. See Joint Stipulation of Facts, 12/8/17, at ¶ 93.

The distribution of seats in Pennsylvania from 1966 to 2010 is shown below:

Year Districts Democratic Seats Republican Seats

Joint Stipulation of Facts, 12/8/17, at ¶ 70.

In the three elections since the 2011 Plan was enacted, Democrats have won the same five districts, and Republicans have won the same 13 districts. In the 2012 election, Democrats won five congressional districts with an average of 76.4% of the vote in each, whereas Republicans won the remaining 13 congressional districts with an average 59.5% of the vote in each, and, notably, Democrats earned a statewide share of 50.8% of the vote, 'an average of 50.4% per district, with a median of 42.8% of the vote, whereas Republicans earned only a statewide share of 49,2% of the vote.

In the 2014 election, Democratic candidates again won five congressional races, ■with an average of 73.6% of the vote in each, whereas Republicans again won 13 congressional districts, with an average of 63.4% Of the vote in each. In 2014, Democrats earned a 44.5% statewide vote share in contested races, whereas Republicans earned a 55.5% statewide vote share in contested races, with a 54.1% statewide share vote in the aggregate.

In the 2016 election, Democrats again won those same five congressional districts, with an average of 75.2% of the vote in each and a statewide vote share of 45.9%, whereas Republicans won those same 13 districts with an average of 61.8% in each and a statewide vote share of 54,1%.

In short, in the last three election cycles, the partisan distribution has been as follows:

Year Districts Democratic Seats Republican Seats Democratic Vote Percentage Republican Vote Percentage

2012 18 5 13 50.8% 49.2%

2014 18 5 13 44.5% 55,5%

2016 18 5 13 45.9% 54,1%

Joint Stipulation of Facts, 12/8/18, at ¶ 102.

II. Petitioners’ Action

Petitioners filed this lawsuit on June 15, 2017, in 'the Commonwealth Court. In Count I of their petition for review, Petitioners alleged that the 2011 Plan violates their rights to free expression and association under Article I, Sections 7 and 20 of the Pennsylvania Constitution. More specifically, Petitioners alleged that the General Assembly created the 2011 Plan by “expressly and deliberately consider[ing] the political views, voting histories, and party affiliations of Petitioners and other Democratic voters” with the intent to burden and disfavor Petitioners’ and other Democratic voters’ rights to free expression and association. Petition for Review, 6/15/17, at ¶¶ 105. Petitioners further alleged that the 2011 Plan had the effect of burdening and disfavoring. Petitioners’ and other Democratic voters’ rights to free expression and association because the 2011 Plan “prevented Democratic voters from electing the representatives of their choice and from influencing the' legislative process” and suppressed “the political views and expression of Democratic voters.” Id. at ¶ 107. They contended the Plan “also violates the Pennsylvania Constitution’s prohibition against retaliation against individuals who exercise their rights under” these articles. Id. at ¶ 108. Specifically, Petitioners alleged that the General Assembly’s “cracking” of congressional districts in the 2011 Plan has resulted in their inability “to elect representatives of their choice or to influence the political process.” Id. at ¶ 112.

In Count II, Petitioners alleged the Plan violates the equal protection provisions of Article 1, Sections 1 and 26 of the Pennsylvania Constitution, and the Free and Equal Elections Clause of Article I, Section 5 of the Pennsylvania Constitution. More specifically, Petitioners alleged that the Plan intentionally discriminates against Petitioners and other Democratic voters by using “redistricting to maximize Republican seats in Congress and entrench [those] Republican members in power.” Id. at ¶ 116. Petitioners further alleged that the Plan has an actual discriminatory effect, because it “disadvantages Petitioners and other Democratic voters at the polls and severely burdens their representational rights,” Id. at ¶ 117. They contended that “computer modeling and statistical tests demonstrate that Democrats receive far fewer congressional seats than they would absent the gerrymander, and that Republicans’ advantage is nearly impossible to overcome.” Id. at ¶ 118. Petitioners claimed that individuals who live in cracked districts under the 2011 Plan are essentially excluded from the political process and have been denied any “realistic opportunity to elect representatives of their choice,” and any “meaningful opportunity to influence legislative outcomes.” Id. at ¶ 119. Finally, Petitioners claimed that, with regard to individuals living in “packed” Democratic districts under the Plan, the weight of their votes has been “substantially diluted,” and their votes have no “impact on election outcomes.” Id. at ¶ 120.

In response to Respondents’ application, on October 16, 2017, Judge Dan Pellegrini granted a stay of the Commonwealth Court proceedings pending the United States Supreme Court’s decision in Gill v. Whitford, No. 16-1161 (U.S. argued Oct. 3, 2017). However, thereafter, Petitioners filed with this Court an application for extraordinary relief, asking that we exercise extraordinary jurisdiction over the matter. On November 9, 2017, we granted the application and assumed plenary jurisdiction over the matter, but, while retaining jurisdiction, remanded the matter to the Commonwealth Court to “conduct all necessary and appropriate discovery, pre-trial and trial proceedings so as to create an evidentiary record on which Petitioners’ claims may be decided.” Supreme Court Order, 11/9/17, at 2. We ordered the court to do so on an expedited basis, and to submit to us findings of fact and conclusions of law no later than December 31, 2017. Id. Finally, we directed that the matter be assigned to a commissioned judge of that court.

The Commonwealth Court, by the Honorable P. Kevin Brobson, responded with commendable speed, thoroughness, and efficiency, conducting a nonjury trial from December 11 through 15, and submitting to us its recommended findings of fact and conclusions of law on December 29, 2017, two days prior to our deadline. Thereafter, we ordered expedited briefing, and held oral argument on January 17, 2018.

III. Commonwealth Court Proceedings

In the proceedings before the Commonwealth Court, that court initially disposed of various pretrial matters. Most notably, the court ruled on Petitioners’ discovery requests, and Legislative Respondents’ objections thereto, directed to gleaning the legislators’ intent behind the passage of the 2011 Plan. By order and opinion dated November 22, 2017, the court concluded that, under the Speech and Debate Clause of the Pennsylvania Constitution, the court “lack[ed] the authority 'to compel testimony or the production of documents relative to the intentions, motivations, and activities of state legislators and their staff with respect to the consideration and passage of’ the 2011 Plan, Commonwealth Court Opinion, 11/22/17, at 7, and so quashed those requests

In addition, Petitioners sought to admit, and Legislative Respondents sought to exclude, certain materials produced by-House Speaker Mike Turzai in the federal litigation in Agre v. Wolf, supra, in response to permitted discovery in that case, along with Petitioners’ expert Dr. Jowei Chen’s expert reports and testimony based on those materials. (As noted, similar discovery was denied in this case, per the Commonwealth Court’s Speech and Debate Clause ruling.) These materials include redistricting maps revealing partisan scoring down to the precinct level, demonstrating that some legislators designing the 2011 Plan relied upon such partisan considerations. Ultimately, the court permitted Dr. Chen’s testimony about these materials, but refused to admit the materials themselves, refused to make any findings about them, see Findings of Fact at ¶ 307, and submitted a. portion to this Court under seal, see Petitioners’ Exhibit 140. Notably, that sealing order required Petitioners to submit both a “Public” and a “Sealed” version of their brief in order to discuss Exhibit 140. Given our disposition of this matter, we do not further address these materials or the court’s evidentiary rulings with respect to them.

In all, the court heard oral argument and ruled on .eight motions in limine.

A. Findings of Fact of the Commonwealth Court

Prior to the introduction of testimony, the parties and Interveners stipulated to certain background faets, much of which we have discussed above, and to the introduction of certain portions of deposition and/or prior trial testimony as exhibits.

1. Voter Testimony

Initially} several Petitioners testified at trial. They testified as to their belief that, under the 2011 Plan, their ability to elect a candidate who represents their interests and point of view has been compromised. William Marx, a resident of Delmont in Westmoreland County, testified that he is a registered Democrat, and that, under the 2011 Plan, he lives in the 12th Congressional District, which is represented by Congressman Keith Rothfus, a Republican. Marx testified that Congressman Rothfus does not represent his views on, inter alia, taxes, healthcare, the environment, and legislation regarding violence against women, and he stated that he has been unable to communicate with him. Marx believes that the 2011 Plan precludes the possibility of having a Democrat elected in his district. N.T. Trial, 12/11/17, at 113-14.

■ Another Petitioner, Mary Elizabeth Lawn, testified that she is a Democrat who lives, in the city of Chester. Under the 2011 Plan, Chester is in the 7th Congressional District, which is represented by Congressman Patrick Meehan, a Republican.' Id. at 134, 137-39. According to Lawn, Chester is a “heavily African-American” city, and,, prior to the enactment of the 2011 Plan, was a part of the 1st Congressional District, which is represented by Congressman Bob' Brady, a Democrat. Id. at 135, 138-39. According to Lawn, since the enactment of the 2011 Plan, she has voted for the Democratic candidate in three state elections, and her candidate did not win any of the elections. Id. at 140. Lawn believes that the 2011 Plan has affected her ability to participate in the political process because she was placed in a largely Republican district where the Democratic candidate “doesn’t really have a chance.” Id. Like Marx, Lawn testified that her congressman does not represent her views on many issues, and that she found her exchanges with his office unsatisfying. Id. at 140-44.

Finally, Thomas Rentschler, a resident of Exeter Township, testified that he is a registered Democrat. N.T. Trial, 12/12/17, at 669. Rentschler testified that he lives two miles from the City of Reading, and that he has a clear “community of interest” in that city. Id. at 682. Under the 2011 Plan, however, Reading is in the" 16th Congressional District, and Rentschler is in the 6th Congressional District, which is represented by Congressman Ryan Costello, a Republican. Id. at 670-71, 677. Rentschler testified that, while he voted for the Democratic candidate in the last three state elections, all three contests were won by the Republican candidate. Id. at 673. In Rentschler’s view, the 2011 Plan “has unfairly eliminated [his] chance of getting to vote and actually elect a Democratic candidate just by the shape and the design of the district.” Id. at 674.

2. Expert Testimony

Petitioners presented the testimony of four expert witnesses, and the Legislative Respondents sought to rebut this testimony through two experts of their own. We address this testimony seriatim⅛.

Dr. Jowei Chen

Petitioners presented the testimony of Dr. Jowei Chen, an expert in the areas of redistricting and political geography who holds research positions at the University of Michigan, Stanford University, and Willamette University. Dr. Chen testified that he evaluated the 2011 Plan, focusing on three specific questions: (1) whether partisan intent was the predominant factor in the drawing of the Plan; (2) if so, what was the effect of the Plan on the number of congressional Democrats and Republicans elected from Pennsylvania; and (3) the effect of the Plan on the ability of the 18 individual Petitioners to elect a Democrat or Republican candidate for congress from their respective districts. N.T. Trial, 12/11/17, at 165.

In order to evaluate the 2011 plan, Dr. Chen testified that he used a computer algorithm to create two sets, each with 500 plans, of computer-simulated redistricting plans for Pennsylvania’s congressional districts. Id. at 170. The computer algorithm used to create the first set of simulated plans (“Simulation Set 1”) utilized traditional Pennsylvania districting criteria, specifically: population equality; contiguity; compactness; absence of splits within municipalities, unless necessary; and absence of splits within counties, unless necessary. Id. at 167. The computer algorithm used to create the second set of simulated plans (“Simulation Set 2”) utilized the aforementioned criteria, but incorporated the additional criteria of protecting 17 incumbents, which, according to Dr. Chen, is not a “traditional districting criterion.” Id. at 206. Dr. Chen testified that the purpose of adding incumbent protection to the criteria for the second set of computer-simulated plans was to determine whether “a hypothetical goal by the General Assembly of protecting incumbents in a nonpartisan manner might somehow explain or account for the extreme partisan bias” of the 2011 Plan. Id.

With regard to Simulation Set 1, the set of computer-simulated plans utilizing only traditional districting criteria, Dr. Chen noted that one of those plans, specifically, “Chen Figure 1: Example of a Simulated Districting Plan from Simulation Set 1 (Adhering to Traditional Districting Criteria)” (hereinafter “Simulated Plan 1”), which was introduced as Petitioners’ Exhibit 3, results in only 14 counties being split into multiple congressional districts, as compared to the 28 counties that are split into multiple districts under the 2011 Plan. Id. at 173-74. Indeed, referring to a chart titled “Chen Figure 3: Simulation Set 1: 500 Simulated Plans Following Only Traditional Districting Criteria (No Consideration of Incumbent Protection),” which was introduced as Petitioners’ Exhibit 4, Dr. Chen explained that the maximum number of split counties in any of the 500 Simulation Set 1 plans is 16, and, in several instances, is as few as 11. Id. at 179. The vast majority of the Simulation Set 1 plans have 12 to 14 split counties. Id.

With respect to splits between municipalities, Dr. Chen observed that, under the 2011 Plan, there are 68 splits, whereas the range of splits under the Simulation Set 1 plans is 40 to 58. Id. at 180; Petitioners’ Exhibit 4. Based on the data contained in Petitioners’ Exhibit 4, Dr. Chen noted that the 2011 Plan “splits significantly more municipalities than would have resulted from the simulated plans following teadi-tional districting criteria, and [it] also split significantly more counties.” N.T. Trial, 12/11/17, at 180. He concluded that the evidence demonstrates that the 2011 Plan “significantly subordinated the traditional districting criteria of avoiding county splits and avoiding municipal splits. It shows us that the [2011 Plan] split far more counties, as well as more municipalities, than the sorts of plans that would have arisen under a districting process following traditional districting principles in Pennsylvania.” Id. at 181.

In terms of geographic compactness, Dr. Chen explained that he compared Simulated Plan 1 to the 2011 Plan utilizing two separate and widely-accepted standards. First, Dr. Chen calculated the Reock Compactness Score, which is a ratio of a particular district’s area to the area of the smallest bounding circle that can be drawn to completely contain the district — the higher the score, the more compact the district. Id. at 175. The range of Reock Compactness Scores for the congressional districts in Simulated Set 1 was “about .38 to about .46,” id. at 182, and Simulated Plan 1 had an average Reock Compactness Score range of .442, as compared to the 2011 Plan’s score of .278, revealing that, according to Dr. Chen, the 2011 Plan “is significantly less compact” than Simulated Plan 1. Id. at 175.

Dr. Chen also calculated the Popper-Polsby Compactness Score of both plans. The Popper-Polsby Compactness Score is calculated by first measuring each district’s perimeter and comparing it to the area of a hypothetical circle with that same perimeter. The ratio of the particular district’s area to the area of the hypothetical circle is its Popper-Polsby Compactness Score — the higher the score, the greater the geographic compactness. Id. at 176-77. The range of Popper-Polsby Compactness Scores for congressional districts in the Simulated Set 1 plans was “about .29 up to about .35,” id. at 183, and Simulated Plan 1 -had an average Popper-Polsby Score of .310, as compared to the 2011 Plan’s score of .164, again leading Dr. Chen to conclude that “the enacted map is significantly far less geographically compact” than Simulated Plan 1. Id. at 177.

Utilizing a, chart showing the mean Popper-Polsby Compactness Score- and the mean Reock Compactness Score for each of the 500 Simulation Set 1 plans, as compared to the 2011 Plan, see Petitioners’ Exhibit 5 (“Chen Figure 4: Simulation Set 1: 500 Simulated Plans Following Only Traditional Districting Criteria (No Consideration of Incumbent Protection)”), Dr. Chen opined that “no matter which measure of compactness you use, it’s very clear that the [2011 Plan] significantly and completely sacrifice[s] the traditional district-ing principle of geographic compactness compared to the sorts of plans that would have emerged under traditional districting principles.” N.T. Trial, 12/11/17, at 184.

Dr. Chen next addressed the 500 Simulation Set 2 Plans, which, as noted above, included the additional criteria of protecting the 17 incumbents. Dr. Chen stated that, in establishing the additional criteria, no consideration was given to the identities or party affiliations of the incumbents. Id. at 208. One of the Simulation Set 2 plans, “Chen Figure 1A: Example of a Simulated Districting Plan from Simulation Set 2 (Adhering to Traditional Districting Criteria And Protecting 17 Incumbents)” (hereinafter "“Simulated Plan l'A”), which was introduced’ as Petitioners’ Exhibit 7, resulted in only 15 counties being split into multiple congressional districts, ■ as compared to the 28 counties that are split into multiple districts under the 2011 Plan. Id. at 213. Referring to Petitioners’ Exhibit 8, titled “Chen Figure- 6: Simulation Set 2: 500 Simulated Plans Following Traditional Districting Criteria and Protecting 17 Incumbents/’ Dr. Chen further observed that the 2011 Plan split more municipalities (68) than any of the Simulated Set 2 plans, which resulted in a range of splits between 50 and 66. Based on this data, Dr. Chen opined:

We’re able to conclude from [Petitioners’ Exhibit 8] that the [2011 Plan] subordinate[s] the traditional districting criteria of avoiding county splits and avoiding municipal splits and the subordination of those criteria was not somehow justified or explained or warranted by an effort to protect 17 incumbents in an nonpartisan manner. To put that in -layman’s terms, an effort to protect incumbents would not have justified splitting up as many counties and as many municipalities as we saw split up, in the [2011 Plan].

Id. at 217.

With respect to geographic compactness, Dr. Chen explained that Simulated Plan 1A had an average Reock Compactness Score of .396, as compared to the 2011 Plan’s score of .278, and Simulated Plan 1A had a Popper-Polsby Compactness Score of .273, as compared to the 2011 Plan’s score of .164. Id. at 214; Petitioners’ Exhibit 7. Based on an illustration of the mean Popper-Polsby Compactness Score and the mean Reock Compactness Score for each of the 500 Simulation Set 2 plans, as compared to the 2011 Plan, see Petitioners’ Exhibit 9 (“Chen Figure 7: Simulation Set 2: 500 Simulated Plans Following Tra-ditio'nal'Districting Criteria and Protecting 17 Incumbents”), Dr. Chen concluded that the 2011 Plan “significantly subordinated' [the] traditional districting criteria of geographic compactness and that subordination of geographic compactness of districts was not somehow justified or necessitated or explained by a hypothetical effort to protect 17 incumbents.” N.T. Trial, 12/11/17, at 220.

Dr. Chen also testified regarding the partisan breakdown of the 2011 Plan. Dr. Chen explained that he requested and obtained from the Department of State the actual election data for each voting precinct in Pennsylvania for the six 2008 and 2010 statewide ■ elections. Id. at 185-86.

Those elections included the elections for the President, Attorney General, Auditor General, and State Treasurer in 2008, and the United States Senate election and the state gubernatorial election in 2010. Id. at 187. The election data obtained by Dr. Chen indicated how many votes were cast for each party candidate. Id. at 189. By overlaying the precinct-level election results on top of the geographic boundaries as shown on a particular map, he was able to determine whether a particular district had more Republican or Democratic votes during the elections. Id. at 196-97. Those districts that had more Republican votes would, naturally, be classified as Republican.

Dr. Chen.observed that, under the 2011 Plan, 13 of the 18 congressional districts are classified as Republican. Id. at 198. However, when Dr. Chen overlaid the precinct-level election results on Simulated Plan 1, only 9 of the 18 congressional districts would be classified as Republican. Id. at 197. Indeed, in the 500 Simulation Set 1 plans, the highest number of classified Republican districts was 10, and in none of the simulated plans would 13 of the congressional districts be classified as Republican. Id. at 200. Based on this data, Dr. Chen stated “I’m able to conclude with well-over 99.9 percent statistical certainty that the [2011 Plan’s] creation of a 13-5 Republican advantage in Pennsylvania’s Congressional delegation is an outcome that would never have emerged from a districting process adhering to and following traditional districting principles.” Id. at 203-04.

Moreover, Dr. Chen testified that, even under the Simulation Set 2 plans, which took into account preservation of incumbent candidates, none of the 500 plans resulted in a Republican District/Democratic District ratio of more than 10 to 8. Id, at 221-22; Petitioners’ .Exhibit 10. Based on a comparison of the 2011 Plan and .his simulated redistricting plans, Dr. Chen determined that “partisan intent predominated the drawing of the [2011 Plan] ... and the [2011 Plan] was drawn with a partisan intent to create a 13-5 Republican advantage and that this partisan intent subordinated traditional districting principles in the drawing of the enacted plan.” Id. at 166.

Dr. Chen was asked to consider, whether the partisan breakdown of the 2011 Plan might be the result of a “hypothetical effort to produce a certain racial threshold of having one district of over a 56.8 percent African-American voting-age population.” Id. at 245, To answer this question, Dr. .Chen explained that he analyzed the 259 computer-simulated plans from Simulation Sets 1 and 2 that included a congressional voting district with an African-American voting age population of at least 56.8%. Dr. Chen testified that, of those 259 simulated plans, none resulted in a Republican-Democrat congressional district ratio of 13 to 5. Id. at 244-45, 250. Indeed, of the Simulated Set 1 plans, which did not take into account protection of incumbents, the maximum ratio was 9 to 9, and of the Simulated Set 2 plans, which did protect incumbents, the maximum ratio was 11 to 8, and, in one case, was as low as 8 to 11. Id.; Petitioners’ Exhibit Í5 (“Chen Figure 10”). Dr. Chen concluded “the 13-5 Republican advantage of the enacted map is an outcome that is not plausible, even if one is only interested in plans that create one district with over 56.8 percent African-American voting-age population.” N.T. Trial, 12/11/17, at 245.

Dr. Chen also was asked whether the 13-5 Republican advantage in the 2011 Plan could be explained by political geography — that is, the geographic patterns of political behavior. Id. at 251. Dr. Chen explained that political geography can create natural advantages for one party over another; for example, he observed that, in Florida, Democratic voters are often “far more geographically clustered in urban areas,” whereas Republicans “are much more geographically spaced out in rural parts” of the state, resulting in a Republican advantage in control over districts and seats in the state legislature. Id. at 252-53.

In considering the impact of Pennsylvania’s political geography on the 2011 Plan, Dr. Chen explained that he measured the partisan bias of the 2011 Plan by utilizing a common scientific measurement referred to as the mean-median gap. Id. at 257. To calculate the mean, one looks at the average vote share per party in a particular district. Id. To calculate the median, one “line[s] up” the districts from the lowest to the highest vote share; the “middle best district” is the median. Id. at 258. The median district is the district that either party has to win in order to win the election. Id. Dr. Chen testified that, under the 2011 Plan, the Republican Party has a mean vote share of 47.5%, and a median vote share of 53.4%. Id. at 261; Petitioners’ Exhibit 1, at 20. This results in a mean-median gap of 5.9%, which, according to Dr. Chen, indicates that, under the 2011 Plan, “Republican votes ... are spread out in a very advantageous manner so as to allow — in a way that would allow the Republicans to more easily win that median district.” N.T. Trial, 12/11/17, at 259. The converse of this mean-median gap result is that Democratic voters “are very packed into a minority of the districts, which they win by probably more comfortable margins,” which makes it “much harder for Democrats under that scenario to be able to win the median district. So, in effect, what that means is it’s much harder for the Democrats to be able to win a majority of the Congressional delegation.” Id. at 260.

Dr. Chen recognized that “Republicans clearly enjoy a small natural geographic advantage in Pennsylvania because of the way that Democratic voters are clustered and Republican voters are a bit more spread out across different geographies of Pennsylvania.” Id. at 255, However, Dr. Chen observed that the range of mean/median gaps created in any of the Simulated Set 1 plans was between “a little over 0 percent to the vast majority of them being under 3 percent,” with a maximum of 4 percent. Id. at 262-63; Petitioners’ Exhibit 16 (“Chen Figure 5”). Dr. Chen explained that this is a “normal range,” and that a 6% gap “is a very statistically extreme outcome that cannot be explained by voter geography or by traditional districting principles alone.” N.T. Trial, 12/11/17, at 263-64. Dr. Chen noted that the range of mean/median gaps created by any of the Simulated Set 2 plans also did not approach 6%, and, thus, that the 2011 Plan’s “extreme partisan skew of voters is not an outcome that naturally emerges from Pennsylvania’s voter geography combined with traditional districting principles and an effort to protect 17 incumbents in a nonpartisan manner. It’s not a plausible outcome given those conditions.” Id. at 266; Petitioners’ Exhibit 17 (“Chen Figure 9”).

In sum, Dr. Chen “statistically conclude[d] with extremely high certainty ... that, certainly, there is a small geographic advantage for the Republicans, but it does not come close to explaining the extreme 13-5 Republican advantage in the [2011 Plan].” N.T. Trial, 12/11/17, at 255-56.

Ultimately, the Commonwealth Court found Dr. Chen’s testimony credible; specifically, the court held that Dr. Chen’s testimony “established that the General Assembly included factors other than nonpartisan traditional districting criteria in creating the 2011 Plan in order to increase the number of Republican-leaning congressional voting districts.” Findings of Fact at ¶ 309. The court noted, however, that Dr. Chen’s testimony “failed to take into account the communities of interest when creating districting plans,” and “failed to account for the fact that courts have held that a legislature may engage in some level of partisan intent when creating redistricting plans.” Id. at ¶¶ 310, 311.

Dr. John Kennedy

Petitioners next presented the testimony of Dr. John Kennedy, an expert in the area of political science, specializing in the political geography and political history of Pennsylvania, who is a professor of political science at West Chester University. Dr. Kennedy testified that he analyzed the 2011 Plan “to see how it treated communities of interest, whether there were anomalies present, whether there are strangely designed districts, whether there are things that just don’t make sense, whether there are tentacles, whether there are isthmuses, whether there are other peculiarities.” N.T. Trial, 12/12/17, at 580. Dr. Kennedy also explained several concepts used to create a gerrymandered plan. For example, he described that “cracking” is a method by which a particular party’s supporters are separated or divided so they cannot form a larger, cohesive political voice. Id. at 586. Conversely, “packing” is a process by which individual groups who reside in different communities are placed together based on their partisan performance, in an effort to lessen those individuals’ impact over a broader area. Id. Finally, Dr. Kennedy defined “highjacking” as the combining of two congressional districts, both of which have the majority support of one party — the one not drawing the map — thereby forcing two incumbents to run against one another in the primary election, and automatically eliminating one of them. Id. at 634.

When asked specifically about the 2011 Plan, Dr. Kennedy opined that the 2011 Plan “negatively impacts Pennsylvania’s communities of interest to an unprecedented degree and contains more anomalies than ever before.” Id. at 579. For example, Dr. Kennedy noted that Erie County, in the 3rd Congressional District, is split under the 2011 Plan for “no apparent nonpartisan reason,” when it had never previously been split. Id. at 591. According to Dr. Kennedy, Erie County is a historically Democratic county, and, in splitting the county, the legislature “cracked” it, diluting its impact by pushing the eastern parts of the county into the rural and overwhelmingly Republican 5th Congressional District. Id. at 597; see Petitioners’ Exhibit 73.

Dr. Kennedy next addressed the 7th Congressional District, which he noted “has become famous certainly systemwide, if not nationally, as one of the most gerrymandered districts in the country,” earning the nickname “the Goofy kicking Donald district.” N.T. Trial, 12/11/17, at 598-99; see Joint Exhibit 12. According to Dr. Kennedy, the 7th Congressional District was historically based in southern Delaware County; under the 2011 Plan, it begins in Delaware County, moves north into Montgomery County, then west into Chester County, and finally, both north into Berks County and south into Lancaster County. At one point, along Route 30, the district is contiguous only by virtue of a medical facility, N.T. Trial, 12/11/17, at 600-01; at another point, in King of Prussia, it remains connected by a single steak and seafood restaurant. Id. at 604. Dr. Kennedy further observed that the 7th Congressional District contains 26 split, municipalities. Id, at 615.

Dr. Kennedy offered the 1st Congressional District as an example of a district which has been packed. Id. at 605; see Petitioners’ Exhibit 70. He described that the 1st Congressional District begins in Northeast Philadelphia, an overwhelmingly Democratic district, and largely tracks the Delaware River, but occasionally reaches out to incorporate other Democratic communities, such as parts of the city of Chester and the town of Swarth'more. N.T. Trial, 12/11/17, at 605-08.

Dr. Kennedy also discussed , the 4th Congressional District, as shown in Petitioners’ Exhibit 75, observing that the. district is historically “a very Republican district.” Id. at 631. In moving the northernmost tip of the City of Harrisburg, which is predominantly a Democratic city, to the 4th Congressional District from the district it previously shared with central Pennsylvania and the Harrisburg metro area, which are part of the same community of interest, the 2011 Plan has diluted the Democratic voté in Harrisburg. Id. at 631-32.

In sum, Dr. Kennedy concluded that the 2011, Plan “gives precedence to political considerations over considerations of communities of interest and disadvantages Democratic voters, as compared to Republican voters. This is a gerrymandered map.” Id. at 644, The Commonwealth Court found Dr. Kennedy’s testimony credible. However, it concluded that Dr. Kennedy “did not address the intent behind the 2011 Plan,” and it specifically “disregarded” Dr. Kennedy’s opinion that the 2011 Plan was an unconstitutional gerrymander as an opinion on the ultimate question of law. in this case. Findings of Fact at ¶¶ 339-41.

Dr. Wesley Pegden

Petitioners next presented the testimony of Dr. Wesley Pegden, an' expert in the area of mathematical probability, and professor of mathematical sciences at Carnegie Mellon University. Dr. Pegden testified that he evaluated the 2011 Plan to determine whether it “is an outlier with respect to partisan bias and, if so, if that could be explained by the interaction of political geography and traditional districting criteria in Pennsylvania.” N.T. Trial, 12/13/17, at 716-17. In evaluating the 2011 Plan, Dr. Pegden utilized a computer algorithm that starts with a base plan — in this case, the 2011 Plan — and then makes a series of small random changes to the plan. Dr. Pegden was able to incorporate various parameters, such as maintaining 18 contiguous districts, maintaining ‘ equal population, and maintaining compactness. Id. at 726. Dr. Pegden then noted whether the series of small changes resulted in a decrease in partisan bias, as measured by the mean/median. Id. at 722-23.

The algorithm made .approximately 1 trillion computer-generated random changes to the 2011 Plan, and, of the resulting plans, Dr. Pegden determined that 99.999999% of them had’ less partisan bias than the 2011 Plan. Id. at 749; Petitioners’ Exhibit 117, at 1. Based on this data, Dr. Pegden concluded the General Assembly “carefully crafted [the 2011 Plan] to ensure a Republican advantage.” Petitioners’ Exhibit 117, at 1. He further testified the 2011 Plan “was indeed an extreme outlier with respect to partisan bias in a way that could not be explained by the interaction of political geography and the districting criteria” that he considered. N.T. Trial, 12/13/17, at 717.

The Court found Dr. Pegden’s testimony to be credible; however, it noted that, like Dr. Chen’s testimony, his testimony did not take into account “other districting considerations, such as not splitting municipalities, communities of interest, and some permissible level of incumbent protection and partisan intent.” Findings of Fact at ¶¶ 360-61. Further, as with Dr. Kennedy, the Commonwealth Court “disregarded” Dr. Pegden’s opinion that the 2011 Plan was an unconstitutional gerrymander as an opinion on a question of law. Id. at ¶ 363.

Dr. Christopher Warshaw

Petitioners next presented the testimony of Dr. Christopher Warshaw, an expert in the field of American politics — specifically, political representation, public opinion, elections, and polarization — and professor of political science at George Washington University. Dr. Warshaw testified that he was asked to evaluate the degree of partisan bias in the 2011 Plan, and to place any such bias into “historical perspective.” N.T. Trial, 12/13/17, at 836.

Dr. Warshaw suggested that the degree of partisan bias in a redistricting plan can be measured through the “efficiency gap,” which is a formula that measures the number of “wasted” votes for one party against the number of “wasted” votes for another party. Id. at 840-41. For a losing party, all of the party’s votes are deemed wasted votes. For a winning party, all votes over the 50% needed to win the election, plus one, are deemed wasted votes. The practices of cracking and packing can be used to create wasted votes. Id. at 839. He explained that, in a cracked district, the disadvantaged party loses narrowly, wasting a large number of votes without winning a seat; in a packed district, the disadvantaged party wins ■ overwhelmingly, again, wasting a large number of votes. Id. at 839-40. To calculate the efficiency gap, Dr. Warshaw calculates the ratio of a party’s wasted? votes over the total number of votes cast in the election, and subtracts one party’s ratio from the ratio for the other party. The larger the number, the greater the partisan bias. For purposes of evaluating the 2011 Plan, Dr. Warshaw explained that an efficiency gap of a negar five percentage represents a Republican advantage, and a positive percentage represents a Democratic ¡advantage. Id. at 842. (The decision of which party’s gap' is deemed negative versus positive — the scale’s polarity — is arbitrary. Id. ,-at 854.) He summed up the approach as follows:

The efficiency gap is just a way of.translating this-intuition that what gerrymandering is ultimately about is efficiently translating votes into seats by wasting as many of your opponent’s supporters as possible and as few- as possible — as possible of your own. So-it’s really just a formula that captures this intuition that that’s what gerrymandering is at its core.

Id. at 840.

Dr. Warshaw testified that, historically, in states with moré than six congressional districts, the efficiency gap is close to 0%. An efficiency gap of .0% indicates no partisan advantage. Id. at 864. He explained that 75% of the time, the efficiency gap is between 10% and negative 10%, and, less than 4% of the time, the efficiency gap is outside the range of '20% and negative 20%. Id at 865. •

In analyzing the efficiency gap in Pennsylvania for the -years Í972 through 2016, Dr. Warshaw discovered that, during the 1970s, there was “a very modest” Democratic advantage, but that the efficiency gap was. relatively close to zero. Id. at 870; see Petitioner’s Exhibit 40. In the 1980s and 90s, the efficiency gap indicated no partisan advantage for either party. Id. Beginning in 2000, there was a “very modest Republican advantage,” but the efficiency gaps “were never very far from zero.” Id. at 870-71. However, in 2012, the efficiency gap in Pennsylvania was negative 24%, indicating that “Republicans had a 24-percentage-point advantage in the districting process.” Id. at 871. In 2014, “Republicans continued to have a large advantage in the districting process with negative 15 percent,” and, in 2016, Republicans “continued to have a very large and robust” advantage with an efficiency gap of negative 19%. Id.

Dr. Warshaw confirmed that, prior to the 2011 Plan, Pennsylvania never had an efficiency gap of 15% in favor of either party, and only once had there been an efficiency gap of even 10%. Id. at 872. Thus, Dr. Warshaw concluded that the efficiency gaps that occurred after the 2011 Plan were “extreme” relative to the prior plans in Pennsylvania. Id. Indeed, he noted that the efficiency gap in Pennsylvania in 2012 was the largest in the country for that year, and was the second largest efficiency gap in modern history “since one-person, one-vote went into effect in 1972.” Id. at 874. The impact of an efficiency gap between 15% and 24%, according to Dr. Warshaw, “implies that Republicans won an average of three to four extra Congressional seats each year over this timespan.” Id. at 873.

When asked to consider whether geography may have contributed to the large efficiency gap in Pennsylvania, Dr. War-shaw stated, “it’s very unlikely that some change in political geography or some other aspect of voting behavior would have driven this change. This change was likely only due to the districts that were put in place.” Id. at 879. With regard to the change in the efficiency gap between the 2010 and 2012 elections, Dr. Warshaw opined that “there’s no possible change in political geography that would lead to such a dramatic shift.” Id. Dr. Warshaw further concluded that “the efficiency gaps that occured immediately after the 2011 Redistricting Plans went into place are extremely persistent,” and are unlikely to be remedied by the “normal electoral process.” Id. at 890-91.

In addition to his testimony regarding the efficiency gap, Dr. Warshaw discussed the concept of polarization, which he defined as the difference in voting patterns between Democrats and Republicans in Congress, id. at 903, and the impact of partisan gerrymandering on citizens’ faith in government. Id. at 953.

The Commonwealth Court found Dr. Warshaw’s testimony to be credible, particularly with respect to the existence of an efficiency gap in Pennsylvania. Nevertheless, the court opined that the full meaning and effect of the gap “requires some speculation and does not take into account some relevant considerations, such as quality of candidates, incumbency advantage, and voter turnout.” Findings of Fact at ¶ 389. The court expressed additional concerns that the efficiency gap “devalues competitive elections,” in that even in a district in which both parties have an equal chance of prevailing, a close contest will result in a substantial efficiency gap in favor of the prevailing party. Id. at ¶ 390. Finally, the court concluded that Dr. War-shaw’s comparison of the efficiency gap in Pennsylvania and other states was of limited value, as it failed to take into consideration whether there were state differences in methods and limitations for drawing congressional districts. Id. at 89-90 ¶ 391.

Dr. Wendy K. Tam Cho

In response to the testimony offered by Petitioners, Legislative Respondents presented the testimony of their own experts, beginning with Wendy K, Tam Cho, Ph.D., a professor at the University of Illinois, who was certified as an expert in the areas of political science with a focus on political geography, redistricting, American elections, operations research, statistics, probability, and high-performance computing; she was called to rebut Dr. Chen’s and Dr. Pegden’s testimony. N.T. Trial, 12/14/17, at 1132. Dr. Cho opined that, based upon her review of one of Dr. Chen’s prior papers, she believed that his methodology was a flawed attempt at a Monte Carlo simulation — ie., a flawed attempt to use random sampling to establish the probability of outcomes. Specifically, Dr. Cho explained that Dr. Chen’s methodology was flawed because, although his algorithm randomly selected an initial voting district from which to compile a redistricting plan, it subsequently followed a determined course in actually compiling it, thereby undermining its ability to establish probabilistic outcomes. Id. at 1137-38. Dr. Cho also criticized Dr. Chen’s algorithm on, inter alia, the basis that it had not been academically validated, id. at 1170-73; that many or all of the alternative plans failed to include all legally applicable and/or traditional redistricting principles “as [she] understand^] them,” id. at 1176; and that the algorithm generated too small a sample size of alternative plans to'establish probabilistic outcomes. Id. at 1181-85.

Dr. Gho testified that, based upon her review of Dr. Pegden’s, published work, she believed his methodology too was flawed, in that it failed to incorporate, ordinary redistricting criteria such as avoiding municipal splits and protecting incumbents. Id. at 1219. ■

Notably, however, Dr. Cho conceded that she did not actually review either Dr. Chen’s or Dr. Pegden’s algorithms or codes, id. at 1141, 1296, and both Dr. Pegden and Dr. Chen testified on rebuttal that the bulk of Dr. Cho’s assumptions regarding their methodology — and, thus, derivatively, her criticisms thereof — were erroneous. Id. at 1368-95; N.T. Trial, 12/15/17, at 1650-75. Ultimately, the Commonwealth Court found Dr. Cho’s testimony incredible “with regard to her criticisms of the algorithms used by Dr. Chen and Dr. Pegden, but credible with regard to her observation that Dr. Pegden’s algorithm failed to avoid municipal splits and did not account for permissible incumbency protection.” Findings of Fact at ¶ 398. Nevertheless, the court found Dr..Cho’s testimony ,did not lessen- the weight of either Dr, Chen’s conclusion that adherence to what he viewed as traditional redistricting. criteria could not explain the 2011 Plan’s partisan bias, or Dr, Pegden’s conclusion that the 2011 Plan is a statistical outlier as compared to maps with nearly identical- population equality, contiguity, compactness, and number of county splits. Id. at ¶¶ 399-400. The court also concluded that Dr. Cho offered no meaningful guidance as to an appropriate test for determining the existence of an unconstitutional partisan gerrymander. Id, at ¶ 401.

Dr. Nolan McCarty

Respondents also presented the testimony of Dr. Nolan McCarty, an expert in the area of redistricting, quantitative election and political analysis, representation and legislative behavior, and voting behavior, and professor of politics and public affairs at Princeton University. Dr. McCarty was asked to comment on the expert reports of Dr. . Chen and Dr. Warshaw. Dr. McCarty explained that he analyzed whether the 2011 Plan resulted in a partisan bias by calculating the partisan voting index (“PVI”). of each congressional district. N.T. Trial, 12/15/17, at 1421. The PVI is calculated by taking the presidential voting returns in a congressional district for the previous two elections, subtracting the national performance of each political party, and then - calculating the average over those two elections. Id. Utilizing the PVI, Dr. McCarty opined that there was no evidence of a partisan advantage to the Republican Party under the 2011 Plan. Id. at 1489-90. He further suggested that, under the 2011 Plan, the Democratic Party should have won 8 of the 18 congressional seats, and that its failure to do so was the result of other factors, including candidate quality, incumbency, spending, national tides, and trends within the electorate. Id. at 1447-48.

Dr. McCarty criticized Dr. Chen’s method Of calculating the partisan performance of a district, opining that it is an imperfect predictor of how a district will vote in congressional elections. Id, at .1458-76. However, Dr. Chen addressed Dr. McCarty’s criticisms on rebuttal, id. at' 1675-701, “to the satisfaction Of the Court." Findings of Fact at ¶ 407.

Dr. McCarty, also criticized Dr. War-shaw’s reliance on the-efficiency gap as an indicator of gerrymandering, contending (1) that the efficiency gap does not take into consideration partisan bias that results naturally from geographic sorting; (2) that proponents of the efficiency gap have not developed principled ways of determining when an efficiency gap is too large to be justified by geographic sorting; and (3) close elections can have an effect on the calculation of efficiency gaps. N.T. Trial, 12/15/17, at 1484; see also Legislative Respondents’ Exhibit 17 at 18-20. He further suggested there are many components to wasted votes that are not related to partisan districting. N.T. Trial, 12/15/17, at 1483-84. Finally, Dr, McCarty criticized Dr. Warshaw’s testimony regarding the effect gerrymandering has on the polarization of political parties. Id. at 1477-82.

The Commonwealth Court found Dr. McCarty’s testimony not credible with regard to his criticism of Dr. Chen’s report; indeed, the court concluded that “the methodology employed by Dr. Chen to calculate partisan performance appears to have been a rehable predictor of election outcomes in Pennsylvania since the enactment of the 2011 Plan.” Findings of Fact at ¶409. Moreover, the Commonwealth Court observed that “Dr. Chen’s methodology resulted in accurate predictions for 54 out of 54 congressional elections under the 2011 Plan.” Id. ■ ■

With regard to Dr. Warshaw’s expert report, the Commonwealth Court likewise determined that Dr. McCarty’s criticisms were not credible to the extent he (1) disagreed that gerrymandering does not exacerbate problems associated with polarization, and (2). suggested that cracking and packing may actually benefit voters. Id. at ¶ 410. The court further rejected as incredible Dr.. McCarty’s criticism of Dr. Warshaw’s reliance on the efficiency gap, noting that “Dr. Warshaw accounted for some geographic sorting in his analysis of the efficiency gap and did not dispute that close elections can impact the calculation of an efficiency' gap.” Id. Although the court credited Dr. McCarty’s testimony that proponents of the efficiency gap have not developed principled methods of determining when an efficiency gap is so large it necessarily evidences partisan gerrymandering, and that wasted votes are not always the result of partisan districting, the Commonwealth Court concluded that Dr. McCarty’s testimony did not lessen (1) “the weight given to Dr. Chen’s testimony that the 2011 Plan is an outlier with respect to its partisan advantage,” or (2) “the weight 'given to Dr. Warshaw’s testimony that an efficiency gap exists in Pennsylvania.” Id. at ¶¶ 411-12. The . court also concluded that Dr. McCarty offered no guidance as to the appropriate test for determining when a legislature’s use of partisan considerations results in unconstitutional gerrymandering. Id. at ¶ 413.

B. Conclusions of Law of the Commonwealth Court

After setting forth its findings of fact, the Commonwealth Court offered recommended conclusions of law. Preliminarily, the court explained that the.federal Constitution requires that seats in the Ünited States House of Representatives be reapportioned decennially among the states according to their populations as determined in the census, and commits post-reapportionment redistricting to the states’ legislatures, subject to federal law. Conclusions of Law at ¶¶ 1-2 (quoting the federal Elections Clause). The court reasoned that, in Pennsylvania, although the General Assembly in performing post-reapportionment redistricting is subject to federal restrictions — e.g., the requirement that districts be as equal in population as possible and the requirements of the Voting Rights Act of 1965 — it is largely free from state restrictions, as its task is not subject to explicit, specific, constitutional or statutory requirements. The Commonwealth Court intimated that, although a party’s claim that a legislative redistricting plan is unconstitutional on the ground that it is a partisan gerrymander is justiciable under federal and state law, id. at ¶ 10 (citing Davis v. Bandemer, 478 U.S. 109, 124-27, 106 S.Ct. 2797, 92 L.Ed.2d .85 (1986); Erfer v. Commonwealth, 568 Pa. 128, 794 A.2d 325, 331 (2002)), it is insufficient to allege that a redistricting plan employs partisan or political classifications per se: rather, a party must demonstrate that the plan employs excessive partisan or political classifications, see id. at ¶¶ 10-15 (citing, inter alia, Vieth, supra, at 307, 124 S.Ct. 1769 (Kennedy, J., concurring) (opining that such a claim predicated on partisan or political classifications per se is nonjusticiable, but that one predicated on the allegation that “the [partisan or political] classifications ... were applied in an invidious manner or in a way unrelated to any legitimate legislative objective” might be justiciable); Erfer, 794 A.2d at 334 (describing such a claim’s justiciability as “not amenable to judicial control or correction save for the most egregious abuses.”); Holt v. 2011 Legislative Reapportionment Comm’n, 614 Pa. 364, 38 A.3d 711, 745 (2012) (“Holt I”) (acknowledging, in the context of state legislative redistricting, that redistricting “has an inevitably legislative, and therefore an inevitably political, element,” but indicating that constitutional requirements function as a “brake on the most overt of potential excesses and abuse”)). The court noted that Petitioners, insofar as they are challenging the 2011 Plan’s constitutionality, bear the burden of proving its unconstitutionality, arid that it is insufficient for them to demonstrate that a better or fairer plan exists; rather, they must demonstrate that the 2011 Plan clearly, plainly, and palpably violates constitutional requirements. See id. at ¶ 16 (citing, inter alia, Singer v. Sheppard, 464 Pa. 387, 346 A.2d 897, 900 (1975)).

Turning to Petitioners’ claims, the Commonwealth Court first rejected Petitioners’ argument that the 2011 Plan violated their rights to free speech pursuant to Article I, Section 7 of the Pennsylvania Constitution and free assembly pursuant to Article I, Section 20 of the Pennsylvania Constitution. The court acknowledged that these provisions predate the First Amendment to the United States Constitution, and that, although their interpretation is often guided by analogy to First Amendment jurisprudence, they provide broader protection of individual freedom of speech and association. The court cited its decision in Working Families Party v. Commonwealth, 169 A.3d 1247 (Pa. Cmwlth. 2017), for the proposition that, where a party challenges a statute as violative of Article I, Sections 7 and 20, the fundamental adjudicative framework is a means-ends test weighing “the character and magnitude of the burden imposed by the [statute] against the interests proffered to justify that burden”: specifically, “ ‘regulations imposing severe burdens on plaintiffs’ rights must be narrowly tailored and advance a compelling state interest^-] [l]esser burdens, however, trigger less exacting review, and a [s]tate’s important regulatory interests will usually be enough to justify reasonable, nondiscriminatory restrictions.’ ” Conclusions of Law at ¶ 25 (quot-tag Working Families Party, 169 A.3d at 1260-61 (internally quoting Timmons v. Twin Cities Area New Party, 520 U.S. 351,117 S.Ct. 1364,137 L.Ed.2d 589 (1997) (internal quotation marks omitted))). The court then explained that this Court has recognized that the right to free speech includes the right to free speech unencumbered by official retaliation:

To prove a claim of retaliation, a plaintiff must establish: (1) the plaintiff was engaged in a constitutionally protected activity; (2) the defendant’s action caused the plaintiff to suffer an injury that would likely chill a person of ordinary firmness from continuing to engage in that activity; and (3) the adverse action was motivated at least in part as a response to the exercise of the plaintiffs constitutional rights.

Id. at ¶26 (quoting Uniontown Newspapers, Inc. v. Roberts, 576 Pa. 231, 839 A.2d 185, 198 (2003) (internal citations and quotation marks omitted)).

Observing that no majority of the United States Supreme Court has yet addressed a challenge to a redistricting plan as violative of the First Amendment and that no Pennsylvania court has yet considered a challenge to a redistricting plan as violative of Article I, Sections 7 and 20, the court remarked that Petitioners are not precluded by the 2011 Plan from freely associating with any candidate or political party or from voting. The court characterized Petitioners’ claims as actually seeking a declaration that they are entitled to a redistricting plan “free of any and all partisan considerations,” noting that such a right was “not apparent in the Pennsylvania Constitution or in the history of gerrymandering decisions in Pennsylvania or throughout the country,” and that both the United States Supreme Court and this Court have previously acknowledged that partisan considerations may play some role in redistricting. Id. at ¶¶ 27-38 (citing Vieth and Holt I).

The court then noted Justice Kennedy’s remarks in Vieth that courts must have some judicially ádministrable standard by which to appraise partisan gerrymanders, and found that Petitioners presented no such standard. Finally, assuming arguen-do that Petitioners’ putative retaliation claim is cognizable under Pennsylvania law, the court found that Petitioners failed to establish the same. Although conceding that Petitioners were engaged in constitutionally-protected political activity, the court first found that they failed to establish that the General Assembly caused them to suffer any injury that would chill a person of ordinary firmness from continuing to engage in such activity, essentially because they remained politically active:

With respect to the second element, Petitioners all continue to participate in the political process. Indeed, they have voted in congressional races since the implementation of the 2011 Plan. The Court assumes that each Petitioner is a person of [at least] ordinary firmness.

Id. at ¶ 34.

The court also determined that Petitioners failed to establish that the General Assembly’s adoption of the 2011 Plan was motivated in part as a response to Petitioners’ participation in the political process, essentially' reasoning that intent to gain a partisan advantage -over a rival-faction is not equivalent to an intent to punish the faction’s voters, that-gleaning the intent of the General Assembly as a body was largely impossible, and that the fact that some Democratic state representatives voted in favor of the 2011 Plan undermined the notion that its intent.was to punish Democratic voters: .

With respect to the third element, Petitioners have similarly failed to adduce evidence that the General Assembly passed the 2011 Plan with any motive to retaliate against Petitioners (or others who voted for Democratic candidates in any particular election) for exercising their right to vote....
Intent to favor one party’s candidates' over another should not be conflated with motive to retaliate against voters for casting their votes for a particular candidate in a prior election. There is no record evidence to suggest that in voting for the 2011 Plan, the General Assembly, or any particular member thereof, was motivated by a desire to punish or •retaliate against Pennsylvanians who voted for Democratic candidates. Indeed, it is difficult to assign a singular and dastardly motive to a branch of government made up of 253- individual members elected from distinct districts with distinct, constituencies and divided party affiliations.....
On final passage of the 2011 Plan in the PA House, of the 197 members voting, 136 voted in the affirmative, with some Republican members voting in the negative and 36 Democratic members voting in' the affirmative. Given the ■ negative Republican votes, the 2011 Plan would not have passed the PA House without Democratic support. The fact that some Democrats voted in favor of the 2011 Plan further militates against a finding or conclusion that the General Assembly passed the 2011 Plan, in whole or in part, as a response to actual votes cast by Democrats in prior elections,'

Id. at ¶¶ 35-37 (paragraph numbering omitted).

. Next, the court rejected Petitioners’ argument that the 2011 Plan violated their rights to equal protection pursuant to Article I, Sections 1 and 26 of the Pennsylvania Constitution (the “Equal Protection Guarantee”) and their right to free and equal elections pursuant to Article I, Section 5 of the Pennsylvania Constitution. The court opined that, “[i]n the context of partisan gerrymandering, the Pennsylvania Supreme Court has stated that the Equal Protection Guarantee is coterminous with the Equal Protection Clause of the Fourteenth Amendment to the United States, Constitution,” Conclusions of Law at ¶ 45 (citing Erfer, 794 A.2d at 332 (citing Love v. Borough of Stroudsburg, 528 Pa. 320, 597 A.2d 1137, 1139 (Í991)); Kramer v. Workers’ Comp. Appeal Bd. (Rite Aid Corp.), 584 Pa. 309, 883 A.2d 518, 532 (2005); Zmflik v. Pennsbury Sch. Dist., 72 A.3d 773, 789 n. 24 (Pa.- Cmwlth. 2013), affd, 629 Pa. 1, 104 A.3d 1096 (2014); Doe v. Miller, 886' A.2d 310, 314 n.9 (Pa. Cmwlth. 2005), affd per curiam, 587 Pa. 502,901 A.2d 495 (2006) )..

The Commonwealth Court further opined that this Court has previously described the Free and Equal Elections Clause as requiring that elections “are publie and open to all qualified electors alike;” that “every voter has .the same right as any other voter;” that “each voter under the law has the right to cast his ballot and have it honestly counted;” that “the regulation of the right to exercise the franchise does not deny the franchise[;]” and that “no constitutional right of the qualified elector is subverted or denied him[,]” but, in the context of partisan gerrymandering, merely reiterates the protections of the Equal Protection Guarantee. Id. at ¶¶ 40 (citing In re 1991 Pa. Legislative Reapportionment Comm’n, 530 Pa. 335, 609 A.2d 132 (1992) (quoting City Council of City of Bethlehem v. Marcincin, 512 Pa. 1, 515 A.2d 1320,1323 (1986)), and Erfer, 794 A.2d at 332).

The court explained that, in In re 1991 Legislative Reapportionment , Comm’n, this Court adopted a standard suggested by a plurality of justices in Bandemer for determining whether a redistricting plan was unconstitutional on the basis of partisan gerrymandering;

A plaintiff raising a gerrymandering claim must establish that there was "intentional discrimination against an identifiable political group and that there was an actual discriminatory effect on that group. In order to establish discriminatory effect, the plaintiff must ■show: (1) that the identifiable group has been, or is projected to be, disadvantaged at the polls; (2) that by being disadvantaged at the polls, the identifiable group will lack political power and be denied fair representation.

Conclusions of Law at ¶ 47 (internal quotation marks, citations, and brackets omitted). The Commonwealth Court acknowledged that Bandemer s and, with it, Erfer's, test, was abrogated by Vieth as a matter of federal law, but, noting that this Court has not yet specifically discarded it, nevertheless endeavored to apply it to Petitioners’ claim. Although acknowledging that Petitioners had established intentional discrimination — in that the General Assembly was likely aware of, and intended, the 2011 Plan’s political consequences — the court determined that Petitioners could not establish that they constituted an identifiable political group:

In light of the standard articulated in Erfer, and based on the evidence adduced at trial, Petitioners have established intentional discrimination, in that the 2011 Plan was intentionally drawn so as to grant Republican candidates an advantage in certain districts within the Commonwealth.... Although the 2011 Plan was drawn to give Republican candidates an advantage in certain districts within the Commonwealth, Petitioners have failed to meet their burden of showing that the 2011 Plan equated to intentional discrimination against an identifiable political group.... Voters who are likely to vote Democratic (or Republican) in a particular district based on the candidates or issues, regardless of the voters’ political affiliation, are not an identifiable political group for purposes of the Equal Protection Guarantee under the Pennsylvania Constitution.

Id. at ¶¶ 51-53 (paragraph numbering omitted).

Moreover, the court found that Petitioners had failed to establish that they would be disadvantaged at the polls or would lack political power or fair representation, noting that they remain free to participate in democratic processes:

While Petitioners contend that Republican candidates who prevail in congressional districts do not represent their particular views on issues important to them and will effectively ignore them, the Court refuses to make such a broad finding based on Petitioners’ feelings. There is no constitutional provision that creates a right in voters to their elected official of choice. As a matter of law, an elected member of Congress represents his or her district in its entirety, even those within the district who' do not share his or her views. This Court will not presume that members of Congress represent only a portion of them constituents simply because some constituents have different priorities and views on controversial issues.... At least 3 of the 18 congressional districts in the 2011 Plan are safe Democratic seats.... Petitioners can, and still do, campaign for, financially support, and vote for their candidate of choice in every congressional election.... Petitioners can still exercise their right to protest and attempt to influence public opinion in their congressional district and throughout the Commonwealth .... Perhaps most importantly, Petitioners and likeminded voters from across the Commonwealth can exercise their political power at the polls to elect legislators and a Governor who will address and remedy any unfairness in the 2011 Plan through the next reapportionment following the 2020 U. S. Census.

Conclusions of Law at ¶ 56 (paragraph labeling omitted).

Finally, in a post-script summary, the court reiterated its view that Petitioners had failed to identify a judicially manageable standard for claims of partisan gerrymandering, and noted that it predicated its conclusions of law on what it viewed as the “evidence presented and the current state of the law,” acknowledging that there are matters pending before the United States Supreme Court that might impact the applicable legal framework. Id. at ¶ 65 (citing Gill v. Whitford, supra; Benisek v. Lamone No. 17-333 (U.S. jurisdictional statement filed Sept. 1, 2017)).

IV. Arguments

A. Petitioners and Aligned Respondents and Amici

We now address the arguments presented to this Court. We begin with Petitioners, those Respondents arguing that Petitioners are entitled to relief, and Petitioners’ supporting amici.

Petitioners first assert that the 2011 Plan violates the free expression and free association clauses of the Pennsylvania Constitution, see Pa. Const, art. I, §§ 7, 20, which, they highlight, pre-date the First Amendment and provide broader protections for speech' and associational rights than those traditionally recognized under the federal Constitution. Consistent with that notion, Petitioners emphasize that, in contrast to federal challenges to laws restricting the freedom of expression, which are assessed under the rubric of intermediate scrutiny, courts apply the more exacting strict scrutiny standard to challenges to such laws under the Pennsylvania Constitution. See Petitioners’ Brief at 46-47 (citing Pap’s A.M. v. City of Erie, 571 Pa. 375, 812 A.2d 591 (2002) (“Pap’s II”)).

According to Petitioners, these broad protections under the Pennsylvania Constitution’s Article I, Section 7 free expression clause necessarily extend to the act of voting, as voting constitutes direct “personal expression of favor or disfavor for particular policies, personalities, or laws,” Petitioners’ Brief at 47-48 (quoting Commonwealth v. Cobbs, 452 Pa. 397, 305 A.2d 25, 27 (1973)), and gives voters a firsthand opportunity to “express their own political preferences.” Id. (quoting Norman v. Reed, 502 U.S. 279, 288, 112 S.Ct. 698, 116 L.Ed.2d 711 (1992)). Petitioners further suggest that the political nature of the expression inherent in voting deserves even greater protection than other forms of expression, as “the right to participate in electing our political leaders” is the most “basic [right] in our democracy.” Id. (quoting McCutcheon v. FEC, — U.S. -, 134 S.Ct. 1434, 1440-41, 188 L.Ed.2d 468 (2014) (plurality)).

While Petitioners recognize that, in the instant matter, the 2011 Plan does not entirely limit Democratic voters’ political expression, they note that laws which' discriminate against or burden protected expression based on content or viewpoint-including those laws which render speech less effective — are nevertheless subject to strict scrutiny analysis. Petitioners’ Brief at 49 (citing Ins. Adjustment Bureau v. Ins. Com’r for Com. of Pa., 518 Pa. 210, 542 A.2d 1317, 1323-24 (1988)). Petitioners maintain that such is the case here, as the Plan was drawn to give Republicans an advantage in 13 out of 18 congressional districts (see Conclusions of Law at ¶ 52; Findings of Fact at ¶ 291) and discriminates against the political viewpoint of Democratic voters across the Commonwealth by: splitting traditionally Democratic strongholds to reduce the effectiveness of the Democratic vote — i.e., Erie County, Harrisburg, and Reading; removing predominantly Democratic municipalities from their broader communities and combining them with other Democratic municipalities to dilute the weight of the Democratic vote — i.e., Swarthmore, Ea-ston, Bethlehem, Scranton, Wilkes-Barre, and the Allegheny River Valley; or knitting together “disparate Republican precincts while excising Democratic strongholds” to diminish the representational rights of Democrats — i.e., Pennsylvania’s 12th District. Petitioners’ Brief at 52.

As further proof of the diminished value of the Democratic vote under the 2011 Plan, Petitioners emphasize that, in each of the past three elections, Democrats won only 5 of the 18-seats,.despite winning the majority of the ■ statewide congressional vote in 2012 and nearly half of that vote in 2014 and 2016. Petitioners also rely upon the experts’ testimony and alternative plans, described above, which they contend .constitute “powerful evidence” of the intent to disadvantage Democratic voters. Id at 53 (quoting Holt I, 38 A.3d at 756-57).,

Jn light of the above evidence, Petitioners argue that the 2011 Plan does not satisfy strict scrutiny — or any scrutiny, for that matter — because Legislative Respondents failed to identify any legitimate, much less compelling, governmental interest served by drawing the congressional district boundaries to disadvantage Democratic voters. As. such, Petitioners criticize the Commonwealth Court for failing to address whether the Plan constitutes viewpoint discrimination and for failing to assess the Plan with any measure of judicial scrutiny — strict scrutiny or otherwise.

While the Commonwealth Court found that Petitioners failed to offer a manageable standard for determining when permissible partisanship in drawing districts becomes unconstitutional, . Petitioners maintain that the 'Constitutional prohibition against viewpoint discrimination and the strict scrutiny standard are indeed the appropriate standards by which to assess their claim, noting that courts have long applied modern constitutional principles to invalidate traditionally acceptable practices, such as the gerrymandering employed in. the instant case. Petitioners’ Brief at 55. (citing Elrod v. Burns, 427 U.S. 347, 96. S.Ct. 2673, 49 L.Ed.2d 547 (1976) (holding that the First Amendment to the United States Constitution prohibited the practice of terminating government employees on a partisan basis); Reynolds v. Sims, 377 U.S, 533, 579, 84 S.Ct. 1362, 12 L.Ed.2d 506 (1964) (invalidating the practice of drawing legislative districts with unequal population)). Petitioners additionally take issue with the Commonwealth Court’s conclusion that there is no right to a “nonpartisan, neutral redistricting process,” Conclusions of Law at ¶ 30, noting that the cases upon which the Commonwealth Court relied in reaching this conclusion were equal protection cases, and, thus, distinguishable from free speech-based gerrymandering challenges, which the high Court allowed to proceed in Shapiro v. McManus, — U.S. —, 136 S.Ct. 450, 193 L.Ed.2d 279 (2015). Petitioners’ Brief at 57 (citing Erfer, 794 A.2d at 328 n.2).

Based on the foregoing, Petitioners urge this Court to find that.the Pennsylvania Constitution categorically prohibits partisan gerrymandering to any degree, as it “serves no good purpose and offers no societal benefit.” Id. However, Petitioners argue that, even if some partisan considerations were permitted in drafting the map of congressional districts, this Court should nevertheless hold that the 2011 Plan’s “extreme and obvious viewpoint discrimination” is unconstitutional. Id, at 58. Petitioners- offer that, at a minimum, the subordination of traditional districting criteria in an attempt to disadvantage a party’s voters based on their political beliefs, as they claim Respondents did in the instant case, should be prohibited.

Alternatively, Petitioners allege that the 2011 Plan impermissibly retaliates against Democratic voters based upon their voting histories and party affiliation. Petitioners note that, to establish a free-speech retaliation claim in the context of redistricting, a party must establish that: (1) the plan intended to burden them “because of how they voted or the political party with which they were affiliated”; (2) they suffered a “tangible and concrete adverse effect”; and (3) the retaliatory intent was a “but for” cause of their injury. Id. at 59-60 (quoting Shapiro v. McManus, 203 F.Supp.3d 579, 596-98 (D. Md. 2016)). Petitioners maintain that they have satisfied each of the three elements of this test and that the Commonwealth Court erred in finding otherwise.

With respect to the first retaliation prong, Petitioners assert that the materials provided by Speaker Turzai in the federal litigation, discussed above, are “direct, conclusive evidence that the mapmakers drew district boundaries to disadvantage Democratic voters specifically based on their voting histories, which the mapmakers measured for every precinct, municipality, and county in Pennsylvania.” Id. at 60 (emphasis original). Petitioners claim this is further evidenced by the testimony of their experts, which demonstrated that the mapmakers used Democratic voters’ past voting history when “packing and cracking” legislative districts to subject those voters to disfavored treatment. Id. Regarding the second prong, Petitioners argue that they proved the Plan caused them to suffer a tangible- and concrete adverse effect — namely,’ losing several seats statewide. Finally, as to the third prong, Petitioners contend that they would have won at least several more seats had the Plan not been drawn to intentionally burden Democratic voters based on their past voting histories.

In rejecting their claim, the Commonwealth Court relied upon the three-part test in Uniontown Newspapers, which required, inter alia, the challenger to establish that the action caused “an injury.that would likely chill a person of ordinary firmness from continuing to engage in that activity.” Uniontown Newspapers, 839 A.2d at 198. However, Petitioners submit that doing so was improper because “chilling” is not an element of a constitutional retaliation claim. Rather, according to Petitioners, the focus on “chilling” in Union-town Newspapers was due to the fact that it was the only injury alleged in the case, not because it was the only cognizable injury in a retaliation case. Indeed, Petitioners suggest that they suffered multiple concrete harms wholly separate from any chilling, which they claim is sufficient to establish the second prong of the retaliation test. .In any event, Petitioners argue that they were, in fact, chilled, as, objectively, the Plan’s “uncompetitive districts clearly would deter many ‘ordinary’ persons from voting.” Petitioners’ Brief at 63.

Lastly, Petitioners reject the Commonwealth Court’s conclusion that the General Assembly lacked a retaliatory motive, noting the “overwhelming evidence” — including 'the documents produced by Speaker Turzai — conclusively established that the mapmakers considered Democrats’ votes in prior elections when drawing the map to disadvantage Democratic voters.

Petitioners next argue that the Plan violates equal protection principles and the Free and Equal Elections Clause of the Pennsylvania Constitution. Id. at 64 (quoting Pa. Const, art I, §§ 1, 5, 26). Specifically, principally relying upon the standard articulated in Erfer, Petitioners explain that a congressional districting map . violates, the equal protection clause if it reflects “intentional . discrimination against an identifiable political group” and if “there was an actual discriminatory effect on that group.” Id. at 65 (quoting Erfer, 794 A.2d at 332). First, regarding the intentional discrimination requirement, Petitioners maintain that the overwhelming evidence proved that the 2011 Plan intentionally discriminated against Democratic voters, • noting the Commonwealth Court specifically found that such discrimination occurred. Second, with respect to the identifiable political group requirement, Petitioners argue that Democratic voters do, in fact, constitute an identifiable political group, citing the statistical evidence from Dr. Chen regarding the high correlation in the level of support for Democratic candidates in particular geographic units and Dr. Warshaw’s expert opinion with respect to the highly predictable nature of congressional elections based on political party-

Third, Petitioners assert that the Plan had an actual discriminatory effect on Democratic voters in the Commonwealth, arguing that, thereby, they have been discriminated against in an exercise of their civil right to vote in violation of Article I, Section 26, and deprived of an “equal” election in violation of the Free and Equal Elections Clause. As noted, at least as a matter of equal protection, Petitioners must prove: (1) that the Plan created disproportionate results at the polls, and (2) that they have “essentially been shut out of the political process.” Erfer, 794 A.2d at 333. Petitioners allege, based upon the evidence detailed above, that they satisfy the first element because drawing the Plan to purposely diminish the effectiveness of Democrats’ votes and to give Republicans the advantage at the polls created disproportional election results, denying Democrats political power and fair representation. Petitioners submit, however, that the second “shut out of the political process” element should be eliminated because it is vague and “unwoi’kable,” claiming that Er-fer provided no guidance regarding the type of evidence that would satisfy that standard, and that Bandemer, supra, upon which Erfer was based, did not impose such a requirement. Petitioners further suggest that imposing an “essentially shut out” requirement is counterintuitive, as it would allow partisan map drawers to continue to politically gerrymander so long as the minority party receives some of the congressional seats. In any event, Petitioners argue that, because the Plan artificially deprives Democratic voters of the ability to elect a Democratic representative, and, given the extreme political polarization between the two political parties, Republican representatives will not adequately represent Democrats’ interests, thus shutting Democratic voters out of the political process.

Finally, Petitioners reject the Commonwealth Court’s conclusion that the Plan satisfies equal protection principles because Democrats potentially will have the opportunity to influence the new map in 2020. Petitioners emphasize that “the possibility that the legislature may itself change the law and remedy the discrimination is not a defense under the Pennsylvania Constitution,” as, under that logic, every discriminatory law would be constitutional. Petitioners’ Brief at 73.

Petitioners requested that this Court give the legislature two weeks to develop a new, constitutional plan that satisfies nonpartisan criteria, and that we adopt a plan ourselves with the assistance of a special master if the legislature fails to do so.

Executive Respondents Governor Wolf, Secretary Torres, Commissioner Marks and Lieutenant Governor Stack have filed briefs supporting Petitioners, arguing, for largely the same reasons advanced by Petitioners, that the 2011 Plan violates the free expression and free association provisions of the Pennsylvania Constitution, as well as equal protection principles and the Free and Equal Elections Clause. Further, Executive Respondents agree that the evidence provided by Petitioners was sufficient to establish that the Plan is unconstitutional.

Beyond the points raised by Petitioners, Executive Respondents Wolf, Torres, and Marks assert that, although the Commonwealth Court found that Petitioners were required to provide a standard to assess when partisan considerations in creating a redistricting plan cross the line into unconstitutionality, no such bright line rule was necessary to determine that the Plan was unconstitutional in this case, given the extreme and, indeed, flagrant level of partisan gerrymandering that occurred. Additionally, while the Commonwealth Court suggested that Petitioners’ standard must account for a variety of specific variables such as the number of districts which must be competitive and the constitutionally permissible efficiency gap percentage, Respondents Wolf, Torres, and Marks argue that precise calculations are not required, noting that “courts routinely decide constitutional cases using judicially manageable standards that are rooted in constitutional principles but that are not susceptible of precise calculation.” Wolf, Marks, and Stack Brief at 8 (citing, e.g., BMW of N. Am., Inc. v. Gore, 517 U.S. 559, 585-86, 116 S.Ct. 1589, 134 L.Ed.2d 809 (1996) (declining “to draw a bright line marking the limits of a constitutionally acceptable punitive damages award,” but finding “the grossly excessive award imposed in this case transcends the constitutional limit”)). Id. at 9. Respondents Wolf, Torres, and Marks further observe that this Court, in invalidating a prior state legislative redis-trieting plan as contrary to law in Holt I, expressly rejected “the premise that any predetermined [population] percentage deviation [existed] with which any reapportionment plan [had to comply],” and declined to “set any immovable ‘guideposts’ for a redistricting commission to meet that would guarantee a finding of constitutionality.” Id. at 10 (quoting Holt I, 38 A.3d at 736).

For his part, Respondent Stack adds that, while he concurs with Petitioners’ position that the Plan fails strict scrutiny analysis, in his view, the Plan also fails under the rational basis standard, as the Plan “lacks a legitimate state interest, and instead advances the impermissible interest of achieving partisan advantage.” Stack Brief at 24. Respondent Stack further argues that, “[although the Legislative Respondents proffered the hypothetical state interests of redrawing the district maps to conform to the results of the census, they cannot and do not offer any rational relationship between that interest and the map they drew.” Id. at 27. Additionally, with respect to Petitioners’ claim under the Free and Equal Elections Clause, Respondent Stack emphasizes that “[t]he constitutional requirement of ‘free and equal elections’ contemplates that all voters are to be treated equally.” Id. at 25. As the Plan was overtly drawn to favor Republicans, Respondent Stack maintains that the Plan “exhibits the heavy hand of state action ... offensive to democracy,” violating the Commonwealth’s duty to ensure that it provides free and equal elections. Id. at 26.

Executive Respondents provide additional insight into how this Court should fashion a remedy, noting that, as representatives of the department that administers elections in Pennsylvania, they are uniquely positioned to make suggestions in this regard. Specifically, Respondents Wolf, Torres, and Marks offer that it is still possible to hold the primary on the scheduled May 15 date if a new redistricting map is in place by February 20, 2018. However, they submit that it would also be possible, through a series of internal administrative adjustments and date changes, to postpone the primary elections from May to the summer of 2018, which would allow a new plan to be administered as late as the beginning of April.

As to the process of creating a new plan, Respondents Wolf, Torres, and Marks assert that three weeks is a reasonable time period for the General Assembly and Governor to enact and sign into law a new redistricting plan, noting that the General Assembly previously enacted a revised congressional districting plan within only 10 days of the court’s order to do so. Wolf, Torres, Marks Brief at 25 (citing Vieth v, Pennsylvania, 241 F.Supp.2d 478, 480 (M.D. Pa. 2003), aff'd sub nom. Vieth, 541 U.8. at 267, 124 S.Ct. 1769). However, if the General Assembly fails to enact a plan by the Court’s deadline, Respondents Wolf, Torres, and Marks suggest that this Court should draft a plan upon consideration of the evidence submitted by the parties. Id. at 26 (citing League of Women Voters of Florida v. Detzner, 179 So.3d 258 (Fla. 2015)).

Respondent Stack agrees with the sug-' gestión of Respondents Wolf, Torres, and Marks that this Court may, and indeed should, adopt a new redistricting plan if the General Assembly and the Governor cannot reach -an agreement on a constitutionally valid map in time for the 2018 congressional primaries. Should this Court take that route, Respondent Stack cites favorably one of the maps developed by Dr. Chen — Chen Figure 1, Petitioners’ Exhibit 3 (identified as Simulated Plan 1 above) — which he maintains serves as a good guide, claiming that it meets or exceeds the 2011 Plan based on traditional redistrieting criteria, and provides sufficient data to judge its compliance with traditional districting criteria, as.well as federal Voting Rights Act requirements. Stack Brief at 10-15, 39. Respondent Stack offers that this Court should retain a special .master, who could reference Dr. Chen’s map as a guide in drawing a new map, should the legislature fail to produce a map in a timely fashion.

Amicus Common Cause, like Petitioners, contends that the 2011 Plan violates the Free and Equal Elections Clause of the Pennsylvania' Constitution, asserting thát this clause provides greater protections to the right to vote than the federal Equal Protection Clause,

Relying upon our seminal decision in Edmunds, supra, which provides the framework for analyzing whether a right under, the Pennsylvania Constitution" is more expansive, than its federal counterpart, Common Cause first argues that the text of the Free and Equal Elections Clause demonstrates that it should be viewed as independent from the Equal Protection Clause of the United States Constitution. Common Cause notes that, in contrast to the more general provisions of the Pennsylvania Constitution such as Article I, Sections I and 26, which implicate, but do not specifically address, the right to vote, Article I, Section 5’s proclamation that “[ejections shall be free and equal” and that “no power ... shall at any time interfere to prevent the free exercise of the right of suffrage” is direct and specific, indicating that the clause should not be “subsumed into Sections 1 and 26, let alone federal jurisprudence,” Common Cause Brief at 6-7.

Second, Common Cause argues that the history of the Free and Equal Elections Clause supports giving it independent effect. Specifically, Common Cause highlights that, since as early as 1776, Pennsylvania has recognized the importance of the right to vote, providing in Chapter I, Section VII of the Declaration of Rights that “ail elections ought to be free; and that all free men having a sufficient evident common interest with, and attachment to the community, have a right to elect officers, or to be elected into office.” Id. (quoting Pa. Const, of 1776, ch. I, § VII). Common Cause continues that, in 1790, Pennsylvania adopted the Free and Equal Elections Clause’into its Constitution, but the federal Constitution was, and continued to be, largely silent regarding the right to free and equal elections, containing no comparable provision and leaving “the selection of representatives and senators largely to the states, subject to minimum age and eligibility requirements.” Id. at 8-9. While the United States later adopted the Equal Protection Clause of the. Fourteenth Amendment to the United States Constitution, Common Cause stresses that it did not do so until 1868 — many decades after Pennsylvania had declared free and equal elections a fundamental right. Thus, in light of the temporal differences between the two provisions and the fact that the federal Equal Protection Clause, does not specifically address elections, Common Cause maintains that the Free and Equal Elections Clause and the federal Equal Protection Clause should not be viewed as coterminous. • ■ ■

Common Cause also suggests that Pennsylvania case law supports giving the Free and Equal Elections Clause independent effect, noting that this Court has interpreted the clause since as early as the 1860s, when the Court explained that elections are made equal by “laws which shall arrange all the qualified electors into suitable districts, and make their votes equally potent in the election; - so that some shall not have more votes than others, and that all shall have an equal share in filling the offices of the Commonwealth,” Id. at 11 (quoting Patterson v. Barlow, 60 Pa. 54, 75 (Pa. 1869)). This Court further provided, with respect to the concept of legislative deference under the Free and Equal Elections Clause, that, although the General Assembly enjoys- discretion in creating laws to ensure that elections are equal, the legislature’s actions in this regard may be reviewed “in a case of plain, palpable, and clear abuse of the power which actually infringes on the rights of the electors.” Id. (quoting Patterson, 60 Pa. at 75), Common Cause additionally highlights, that our case law historically has recognized that, the creation of “suitable districts” in accordance with the Free and Equal Elections Clause relies heavily on “the guiding .principles respecting compactness, contiguity, and respect for the integrity of political subdivisions.” Id. at 13 (quoting Holt I, 38 A.3d at 745). Given the significant amount of time between the passage of the Free and Equal Elections Clause and the Fourteenth Amendment to the United States Constitution, as well as the. separate attention that our Court has . given to the Free and Equal Elections. Clause, Common Cause suggests that “[i]t is incoherent to assume, that Pennsylvania’s jurisprudence under the [Free, and Equal Elections Clause], disappeared into the Fourteenth Amendment.” Id. at 11. •

Third, Common Cause argues that the relative, dearth of case law from other jurisdictions, regarding free .and equal elections illustrates that Pennsylvania was a “trailblazer in- guaranteeing the right to vote,” noting that, of -the original 13 states, only the Pennsylvania, Delaware, and Massachusetts Constitutions contained a clause guaranteeing free and equal elections. Id. at 14. While Common Cause offers that at least one other state — Alaska—has found that its state constitution provides greater protection against gerrymandering than the federal Constitution, see Kenai Peninsula Borough v. State, 743 P.2d 1352, 1371 (Alaska 1987), Common Cause suggests that the general lack of comparable provisions in other state constitutions indicates that,. “[a]s in 1776, Pennsylvania should lead the states in declaring the right to free and fair elections, this time by stamping out gerrymandering.” Common Cause Brief at 14.

Lastly, Common Cause asserts that the Pennsylvania Constitution defeats traditional policy arguments made in support of the practice of gerrymandering, such as the purported difficulty in identifying a workable standard to assess constitutional violations and the notion of legislative deference in drawing congressional districts. More specifically, with respect to the difficulty of identifying a standard, Common Cause submits that the three criteria long used for drawing voting districts in Pennsylvania — compactness, contiguity, and integrity of political subdivisions — provide a sufficient standard by which to assess whether an electoral map violates the Free and Equal Elections Clause. Common Cause stresses that, because these criteria are specifically written into the Pennsylvania Constitution, see Pa Const, art. II, § 16 (“representative districts ... shall be composed of .compact and continuous territory as nearly equal in population as practicable .... Unless absolutely necessary no county, city, incorporated town, borough, township or ward shall be divided in forming either a senatorial or representative district”), and have provided the basis for invalidating state legislative district maps in the past, see- Holt I, supra, they are sufficiently precise as to present a feasible standard for evaluating the constitutionality of a congressional district map under the Free and Equal Elections Clause. Additionally, regarding the principle of legislative deference, Common Cause argues that legislative deference does not give the General Assembly unfettered discretion to engage in partisan gerrymandering without judicial interference, noting that, unlike the federal Constitution, Pennsylvania’s Constitution specifically requires the Court to review challenges to state legislative district maps. See Pa. Const, art. II, § 17(d). While Common Cause concedes that the legislature typically enjoys substantial deference in redistricting matters, it maintains that such deference is not warranted in circumstances, such as in the instant case, where the “faction in control of the legislature” used its authority to create political advantage, rather than to create a map which reflects the “true will of the people.” Common Cause Brief at 17.

Asserting that the four Edmunds factors support giving the Free and Equal Elections Clause independent effect, Common Cause concludes that the 2011 Plan violates that provision because, as exhibited by Petitioners’ evidence, it is not compact or contiguous, nor does it respect political subdivision boundaries. Moreover, Common Cause asserts that the secretive manner in which the Plan was created strongly suggests that the legislature drew the congressional districts with the improper, highly partisan motive of benefit-ting the Republican Party, rather than doing so with the will of the people in mind. Under these circumstances, Common Cause argues that this Court should uphold the democratic principles of the Pennsylvania Constitution and strike down the gerrymandered Plan pursuant to the Free and Equal Elections Clause.

Amicus Brennan Center for Justice (“Brennan Center”) likewise argues on behalf of Petitioners that this Court can, and indeed should, strike down the 2011 Plan as unconstitutional. In so asserting, Brennan Center emphasizes that, although some degree of good faith political “give- and-take” is bound to occur with the redistricting process, this case presents a particularly extreme, unconstitutional form of partisan gerrymander which must be remedied by this Court. While the Commonwealth Court below highlighted the difficulty with identifying a workable standard to assess when, precisely, partisan gerrymandering becomes unconstitutional, Brennan Center maintains that “judicial action to stamp out extreme gerrymanders can be focused and limited,” Brennan Center Brief at 6, explaining that cases of extreme, unconstitutional gerrymandering are relatively rare and are easily detectable based upon two, objective indicia: single-party control of the redistricting process and a recent history of competitive statewide elections. Id. at 7. Brennan Center observes that these factors have been present in every state in the past decade which had a congressional districting map showing extreme partisan bias, including Pennsylvania during the creation of the 2011 Plan. Brennan Center further offers that other accepted quantitative metrics, such as the efficiency gap, the seats-to-votes curve, and the mean-median vote share, can measure the level of partisan bias in a state and assist in identifying extreme gerrymandering, noting that the 2011 Plan performed poorly under each of these metrics.

While Brennan Center acknowledges that federal courts have been hesitant to exercise jurisdiction over partisan gerrymandering claims because of concerns over federalism and excessive burdens on the federal docket, Brennan Center suggests that this Court is not subject to the same constraints. Moreover, Brennan Center highlights that the political question doctrine, which has also hamstrung federal courts in partisan gerrymandering cases, does not restrict this Court from acting in such cases, as this Court held that the political question doctrine renders a case non-justiciable only when the Pennsylvania Constitution “explicitly or implicitly” demonstrates “the clear intent to entrust the legislature with the sole prerogative to assess the adequacy of its own effort[s],” id. at 19 (quoting William Penn Sch. Dist. v. Pa. Dep’t of Educ., — Pa. -, 170 A.3d 414, 439 (2017)), and the Pennsylvania Constitution contains no such limitation with regard to interpreting the constitutionality of partisan congressional redistricting.

Finally, Brennan Center contends that extreme partisan gerrymandering, such as in the instant case, is “contrary to fundamental constitutional and democratic values,” undermining both legislative accountability to the people and legislative representativeness. Id. at 15. Brennan Center asserts that finding the Plan unconstitutional in this case will “enhance the legitimacy of Pennsylvania’s democracy” and restore confidence among Pennsylvanians in the political process. Id. at 23.

Similar to the points raised by Petitioners, as amicus, the AFL-CIO argues that the 2011 Plan is unconstitutional under Article I, Sections 7 and 20 and Article I, Section 5 of the Pennsylvania Constitution, which it asserts provides an independent basis for relief. The AFL-CIO further suggests that Article I, Section 1 of the Pennsylvania Constitution, which ensures equality under the law, and Article I, Section 26 of the Pennsylvania Constitution, which protects Pennsylvanians against the denial or discrimination of their civil rights, provide additional bases for relief under state law and support reviewing the Plan under strict scrutiny.

Analyzing each of these provisions pursuant to the Edmunds factors, the AFL-CIO highlights the rich history of the Pennsylvania Constitution, including, most notably, that the Pennsylvania Constitution was at the forefront of-ensuring robust rights associated with representational democracy, such as the-right to freedom of speech and association, the right to equality under the law, and the right to vote in free and equal elections, which, the AFL-CIO notes Pennsylvania, extended, quite remarkably, to those individuals who did not own property. Moreover, with respect to the Free and Equal Elections Clause, the AFL-CIO emphasizes that this Court has specifically stated that elections are free and equal:

when they are public and open to all qualified electors alike: when every voter has the same right as any other voter; when each voter under the law has the right to cast his ballot and have it honestly counted; when the regulation of the right to exercise the franchise does not deny the franchise itself, or make it so difficult as to amount to a denial; and when no constitutional right of the qualified elector is subverted or denied him.

AFL-CIO Brief at 20-21 (quoting Winston v. Moore, 244 Pa. 447, 91 A. 520 at 523 (1914)). The AFL-CIO maintains that the unique history of these provisions demonstrates that they "provide heightened protections beyond any analogous provisions in the federal constitution,” and, thus, provide a separate legal basis for finding the 2011 Plan unconstitutional. Id. at 4.

Amici Bernard Grofman, professor of political science at the University of California, and Keith Gaddie, professor of political science at the University of Oklahoma, echo the call of Petitioners, Executive Respondents, and other amici for this Court to act and provide a check on extreme partisan gerrymandering, highlighting its pernicious nature. Grof-man and Gaddie also provide a suggested standard for assessing partisan gerrymandering cases, proposing that a partisan gerrymander is unconstitutional if each of the following three elements is shown: (1) partisan asymmetry, meaning the districting map had a “disparate impact on voters based on political affiliar tion,” as measured by degree of partisan bias and mean-median gap, Grofman Gaddie Brief at 14; (2) lack of responsiveness of electoral outcomes to voters’ decisions, meaning. representation does not. change despite a change in voter preference from one political party to another; and.(3) causation, meaning intentional discrimination, rather than other, neutral causes, led to the asymmetry and lack of responsiveness, Grofman and Gaddie maintain that their standard is judicially manageable, as it can be applied by courts “coherently and consistently” across cases, and they urge this Court to adopt it. Id. at 36.

Also, as amicus, the American Civil Liberties Union (“ACLU”) argues in support of Petitioners that the 2011 Plan violates the free expression and association clauses of the Pennsylvania Constitution, asserting, consistent with Petitioners’ position, that the Pennsylvania Constitution provides greater protections for these rights than, does the First Amendment to the United States Constitution. The ACLU also notes the unique nature of the Pennsylvania Constitution’s Free and Equal Elections Clause, which, it suggests, grants more robust protections for the right to vote than the- federal Constitution. Further, as a matter of policy, the ACLU suggests that greater protections for speech, associational, and voting rights are consistent with the “marketplace of ideas” concept developed by Justice Oliver Wendell Holmes, which, the ACLU notes, highlights the importance of government view point neutrality in maintaining the free exchange of ideas critical to our democracy, particularly where the electoral proqess is at stake. ACLU Brief at 6-9.

Similar to Petitioners, the ACLU maintains that extreme partisan gerrymandering is unconstitutional, explaining that unconstitutional partisan gerrymandering is “distinct from the inevitable incidental political considerations and partisan effects that may occur,” id. at 22, and, instead, occurs when a state acts with an intent to “entrench” by drawing district “lines for the purpose of locking in partisan advantage regardless of the voters’ likely choices.” Id. at 22-23 (citing Arizona State Legislature, 135 S.Ct. at 2658). The ACLU suggests that such political entrenchment was present in the instant case, and it maintains that the General Assembly’s deliberate effort to discriminate against minority-party voters triggers strict scrutiny, which the ACLU notes the Legislative Respondents have made no effort to satisfy. Thus, the ACLU argues that this Court should find the Plan violates the Pennsylvania Constitution.

Additionally, Political Science Professors, the Pittsburgh Foundation, and Campaign Legal Center have each -filed amicus curiae briefs in support of Petitioners. These amici focus largely on the increasing prevalence of partisan gerrymandering occurring across the United States, which they attribute to sophisticated, ever-evolving technology which makes it more feasible than ever to gather specific data about voters and to utilize that data to “tailor durably biased maps.” Political Science Professors’ Brief at 12. These am-ici warn that instances of extreme partisan gerrymandering will only' worsen as this technology continués to develop.

Turning to the 2011 Plan, these amici all agree that it represents a particularly egregious form of partisan gerrymandering. They suggest that the challenge to the Plan is justiciable under the Pennsylvania Constitution, and they assert that judicially manageable standards exist by which to assess the constitutionality of the Plan. More specifically, the Pittsburgh Foundation offers that a congressional redistricting plan is unconstitutional' if it: “(1) was intentionally designed predominantly to attain a partisan result; (2) largely disregards traditional and accepted districting criteria; and (3) has been demonstrated (or is reliably predicted) to have an actual disparate and unfair impact on a substantial number- of Pennsylvania voters.” Pittsburgh Foundation Brief at 13. Political Science Professors submit that courts should use computer simulations, as well as objective, social science measures, to assess a districting map’s partisan bias, such as the efficiency gap and the mean-median difference. Lastly, Campaign Legal Center argues that this Court should adopt Petitioners’ proposed standard.

B. Legislative Respondents

We now turn to the arguments of the .Legislative Respondents. They contend that districting legislation, such as the 2011 Plan at issue, does not implicate, let alone violate, free speech or associational lights because it “is not directed to voter speech or conduct.” Legislative Respondents’ Brief at 23. Rather, according to Legislative Respondents, the Plan creates “18 equipopulous districts,” giving Petitioners’ votes the same weight as other Pennsylvania voters and fully allowing Petitioners to participate in the political process by voting for the candidate of their choice and associating with any political party or candidate they so choose. Id.

Regarding Petitioners’ reliance on cases involving laws which made speech less effective, Legislative Respondents suggest those decisions are inapplicable to the case at bar because they concern laws which actually restricted speech, whereas the Plan in the instant case allows Democrats to communicate as desired through such means as voting for their preferred candidates, joining the Democratic Party, contacting their representatives, and financially supporting causes they care about. Although Legislative Respondents concede that the Plan might make it more difficult for Petitioners to “persuade a majority of the other 705,000+ voters in their districts to agree with them on the candidate they prefer,” id. at 25, they emphasize that Petitioners have no free speech or associational right to “an agreeable or more persuadable audience,” id. at 26, citing a variety of federal cases holding that the redistricting plans challenged therein did not violate voters’ First Amendment rights. Id. (citing, e.g., League of Women Voters v. Quinn, No. 1:11-CV-5569, 2011 WL 5143044, *2-3 (N.D. Ill. Oct. 28, 2011); Comm. for a Fair and Balanced Map v. Ill. State Bd. of Elections, 835 F.Supp.2d 563, 575 (N.D. Ill. 2011)).

Moreover, relying on this Court’s decision in Holt v. 2011 Reapportionment Commission, 620 Pa. 373, 67 A.3d 1211 (2013) (“Holt II"), Legislative Respondents highlight the “inherently political” nature of redistricting, which, they note, this Court found constitutionally permissible. Legislative Respondents’ Brief at 27 (quoting Holt II, 67 A.3d at 1234). Further, to the extent that Petitioners distinguish in their argument between permissible “political considerations” and what they deem impermissible “partisan intent,” Respondents maintain that “the two concepts are inextricably intertwined,” as “political parties are comprised of constituencies, which in part includes ‘communities of interest’— what Petitioners argue is the ‘good’ side of ‘political’ ” Id. at 28. As such, Legislative Respondents contend that Petitioners’ argument that no partisan considerations should be permitted during the redistricting process runs afoul of Holt II and necessarily must fail. They suggest that, to find otherwise, would allow any Pennsylvania voter to challenge, and potentially invalidate, a plan designed to protect an incumbent or to protect “corhmunities of interest” — a “sweeping rule” that Respondents contend is not justified by the law, the facts, or public policy. Id. at 29-30.

Next, Respondents assert that Petitioners cannot satisfy the requirements of a retaliation claim. Relying upon the Union-town Newspapers test, Legislative Respondents first argue that Petitioners fail to provide record evidence establishing that the 2011 Plan was enacted with a retaliatory motive to coerce Democratic voters into voting differently than they would otherwise vote. To the contrary, Respondents maintain that no legislature would reasonably believe that gerrymandering would coerce voters to vote differently, and they further submit that the record demonstrates that the Plan was passed with bipartisan support, indicating the Plan was not drawn with a “dastardly motive.” Id. at 31. Respondents also contend that Petitioners failed to prove that the Plan “chilled” a person from continuing to participate in the political process, as the evidence of record did not show a decrease in voter turnout or civil participation following the Plan’s enactment. Lastly, Legislative Respondents highlight the fact that political gerrymandering is not typically the type of government conduct associated with a case of retaliation; rather, Respondents note that retaliation claims typically involve overt actions intended to invoke fear in the target, such as police intimidation tactics or organized harassment campaigns.

Next, Legislative Respondents assert that Petitioners failed to prove that the 2011 Plan violated the equal protection and Free and Equal Elections clauses of the Pennsylvania Constitution. Relying upon Erfer, Respondents contend that Petitioners produced no evidence that the Plan was designed to intentionally discriminate against Democratic voters, emphasizing the bipartisan manner in which the Plan was adopted, and claiming that Petitioners’ statistical data does not account for the various nonpartisan factors considered in drawing the Plan, such as preserving the core of existing districts, preserving communities of interest, and protecting incumbents. Respondents also suggest that Democratic voters do not constitute an “identifiable political group” because they encompass a wide range of people beyond those who belong to the Democratic Party, and because Pennsylvania voters frequently split their tickets between Democratic and Republican candidates, making it difficult to clearly identify a voter as solely “Democratic.”

With respect to the second Erfer prong, Respondents maintain that Petitioners failed to establish that the Plan had a discriminatory effect on Democratic voters and, more specifically, failed to prove that the Plan resulted in a lack of political power which .effectively shut out Democrats from the political process. Respondents argue that, contrary to Petitioners’ assertions, this Court specifically found that merely voting .for a political candidate who loses an election does not shut out a voter from the political process, see Erfer, 794 A.2d at 333, and they submit that, in any event, the five “safe” Democratic seats in the congressional delegation demonstrate that Democrats are not shut out. Respondents further observe that, although Petitioners suggest, due to congressional polarization, that Democrats’ interests are not adequately represented by their congressmen, they fail to provide evidence substantiating this claim and fail to identify the interests of Democratic voters which allegedly are not represented in congress, particularly those Democrats who are “split ticket” voters.

Moreover, to the extent that Petitioners suggest that the .second element of the Erfer test should be eliminated as unworkable, Respondents maintain that we.should deny their request, claiming that Petitioners seek to eliminate that element because they are simply unable to meet it. Respondents further argue that, in advocating for the removal of the . second element, Petitioners essentially are seeking a state constitutional right to proportional representation, which the.United States Supreme Court expressly rejected in Bandemer. See Bandemer, 478 U.S. at 139, 106 S.Ct. 2797. In any event, Respondents emphasize that Petitioners have not met their burden of establishing that this Court should depart from Erfer and the federal precedent upon which it relies, as the equal protection guarantees under the United States and Pennsylvania Constitutions are coterminous, and Petitioners do not suggest otherwise.

Respondents further assert that, even if this Court were to abandon the standard articulated in Erfer, Petitioners’ claim would nevertheless fail because, pursuant to recent United States Supreme Court precedent, there is no judicially manageable standard by which to evaluate claims involving equal protection violations due to partisan gerrymandering. See Vieth, 541 U.S. at 292, 124 S.Ct. 1769. Respondents observe that Petitioners do not attempt to offer a judicially manageable standard to apply in place of the Erfer standard, and they nóte that the standards proposed by amici are similarly unavailing, as they each are incompatible with each other.

Additionally, Legislative Respondents contend that policy considerations weigh heavily against this Court creating a new standard, for evaluating partisan gerry-’ mandering claims under Pennsylvania’s equal protection clause, as they claim the legislature is uniquely competent to engage in redistricting, and judicial oversight in this area implicates separation-of-powers concerns. Respondents further suggest that there are a variety of positive elements to using political considerations in redistricting, including preserving “core constituencies’’ and incumbency, as well as the states’ right to establish their districts in the manner they so choose. Moreover, Legislative Respondents highlight various checks on the state redistricting process, such as the “Make -or Alter” provision of the federal Elections Clause of the United States Constitution, the threat of political retaliation when' the political tides turn, and, as in Pennsylvania, legislation which establishes a bi-partisan commission to draw district lines. Nevertheless, ’ should this Court decide to select a new standard, Legislative Respondents submit that they should receive a new trial.

Legislative Respondents conclude by cautioning that this Court should not adopt legal criteria for redistricting beyond those in Pennsylvania’s Constitution, claiming that doing so would infringe on the legislative function and run afoul of the federal Elections Clause. Accordingly, Respondents ask our Court to affirm the Commonwealth Court’s decision and find that Petitioners did not demonstrate that the 2011 Plan clearly, plainly, and palpably violates the Constitution.

C. Intervenors

Intervenors — Republican voters, candidates for office, committee chairpersons, and other active members of the Republican Party — stress that they have invested substantial time, money, and effort in preparing for the upcoming election deadlines based upon the 2011 Plan, and they suggest that this Court should not require a new congressional’ map before the 2018 primaries, as it would be a “monumental task” to educate voters about changes in the congressional districts in time for the election. Intervenors’ Brief at 17. Interve-nors also highlight potential problems with overall voter confusion, as well as various challenges congressional candidates would face as a result of changes to the 2011 Plan during this election cycle, including potentially having to circulate new nomination petitions and having to direct their campaign activities to potentially new voters and demographics. While Executive Respondents maintain 'that the date of the primary could be extended, Intervenors contend that an extension imposed this late in the election cycle would “result in significant logistical challenges for county election administrators,” as well as substantially increase the costs borne by state and county governments. Id, at 29. According to Intervenors, the above-described challenges would be particularly pronounced with respect to the special election for the 18th Congressional District, scheduled for March 13 of this year.

While Intervenors would find, based upon Vieth, that Petitioners have not shown' that their partisan gerrymandering claims are justiciable, should this Court nevertheless find the claims justiciable and the 2011 Plan unconstitutional, they argue that we must give the legislature the first opportunity to correct the Plan, as ordering new districts without giving the legislature the chance to rectify any constitutional violations would raise separation-of-powers concerns. In doing so, Intervenors assert that our Court should follow the standard for relief that this Court endorsed in Butcher v. Bloom, 415 Pa. 438, 203 A.2d 556 (1964), wherein, after finding that the state redistricting plan violated Reynolds, supra, our Court declined to order immediate redistricting in light of the “[sjerious disruption of orderly state election processes and basic governmental functions” that would result from the Court’s immediate action. Intervenors’ Brief at 17 (quoting Butcher, 203 A.2d at 568). Instead, Intervenors note this Court opted to leave the plan in place until after the upcoming election so as to allow the legislature to have a “reasonable opportunity to enact new reapportionment legislation,” giving the legislature almost a full year to do so. Id. at 23 (quoting Butcher, 203 A.2d at 569).

Claiming that the same concerns in Butcher are present in the instant case, Intervenors submit that we should likewise give the legislature a reasonable and adequate time in which to correct the Plan, which they suggest could be in place for the 2020 elections. Further counseling against the immediate remedying of the 2011 Plan’s constitutional deficiencies, In-tervenors highlight the fact that Petitioners, without explanation, waited three election cycles (almost seven years) to bring their claims, indicating that any constitutional issues are not pressing. Intervenors also cite the United States Supreme Court’s pending decision in Gill, which they note may impact the resolution of this case.

V. Analysis

We begin our analysis of the challenge to the 2011 Plan with the presumption that the General Assembly did not intend to violate the Pennsylvania Constitution, “in part because there exists a judicial presumption that our sister branches take seriously their constitutional oaths.” Stilp v. Commonwealth, 588 Pa. 539, 905 A.2d 918, 938-39 (2006); see also 1 Pa.C.S. § 1922(3). Accordingly, a statute is presumed to be valid, and will be declared unconstitutional only ‘ if the challenging parties carry the heavy burden of proof that the enactment “clearly, palpably, and plainly violates the Constitution.” See West Mifflin Area School District v. Zahorchak, 607 Pa. 153, 4 A.3d 1042, 1048 (2010).

Upon review, and for the following reasons, we are persuaded by Petitioners and the other presentation's before us that the 2011 Han clearly, plainly, and palpably violates the Free and Equal Elections Clause of our Constitution.

A. Free and Equal Elections Clause

Pennsylvania’s Constitution, when adopted in 1776, was widely viewed as “the most radically democratic of all the early state constitutions.” Ken Gormley, “Overview of Pennsylvania Constitutional Law,” as appearing in Ken Gormley, ed., The Pennsylvania Constitution A Treatise on Rights and Liberties, 3 (2004). Indeed, our Constitution, which was adopted over a full decade before the United States Constitution, served as the foundation — the template — for the federal charter. Id, Our autonomous state Constitution, rather than a “reaction” to federal constitutional jurisprudence, stands as a self-contained and self-governing body of constitutional law, and acts as a wholly independent protector of the rights of the citizens of our Commonwealth.

The touchstone of interpretation of a constitutional provision is the actual language of the Constitution itself. Ieropoli v. AC & S Corp., 577 Pa. 138, 842 A.2d 919, 925 (2004). “[T]he Constitution’s language controls and must be interpreted in its popular sense, as understood by the people when they voted on its adoption.” Id. In doing so, reading the provisions of the Constitution in any “strained or technical manner” is to be avoided. Jubelirer v. Rendell, 598 Pa. 16, 953 A.2d 514, 528 (2008). Consistent therewith, “we must favor a natural reading which avoids contradictions and difficulties in implementation, which completely conforms to the intent of the framers and which reflects the views of the ratifying voter.” Commonwealth ex rel. Paulinski v. Isaac, 483 Pa. 467, 397 A.2d 760, 766 (1979).

Further, if, in the process of undertaking explication of a provision of the Pennsylvania Constitution, any ambiguity becomes apparent in the plain language of the provision, we follow the rules of interpretation similar to those generally applicable when construing statutes. See, e.g., Robinson Township v. Commonwealth, 623 Pa. 564, 83 A.3d 901, 945 (2013); Commonwealth v. Omar, 602 Pa. 595, 981 A.2d 179, 185 (2009). If the constitutional language is clear and explicit, we will not “delimit the meaning of the words used by reference to a supposed intent.” Robinson Township, 83 A.3d at 945 (quoting Commonwealth ex rel. Mac Galium v. Acker, 308 Pa. 29, 162 A. 159, 160 (1932)). If the words of a constitutional provision are not explicit, we may resort to considerations other than the plain language to discern intent, including, in this context, the occasion and necessity for the provision; the circumstances under which the amendment was ratified; the mischief to be remedied; the object to be attained; and the contemporaneous legislative history. 1 Pa.C.S. §§ 1921, 1922; accord Robert F. Williams, The Brennan Lecture: Interpreting State Constitutions as Unique Legal Documents, 27 Okla. City U. L. Rev. 189, 195 & 200 (2002) (state constitutions, ratified by electorate, are characterized as “voice of the people,” which invites inquiry into “common understanding” of provision; relevant considerations include constitutional convention debates that reflect collective intent of body, circumstances leading to adoption of provision, and purpose sought to be accomplished).

Moreover, the Free and Equal Elections Clause has no federal counterpart, and, thus, our seminal comparative review standard described in Commonwealth v. Edmunds, supra, is not directly applicable. Nonetheless, certain of the Edmunds factors obviously may assist us in our analysis. Jubelirer, 953 A.2d at 524-25; Edmunds, 586 A.2d at 895. Indeed, we have recently employed certain of these factors when analyzing the Environmental Rights Amendment. See Robinson Township 83 A.3d at 944 (“The Environmental Rights Amendment has no counterpart in the federal charter and, as a result, the seminal, comparative review standard described in [Edmunds] is not strictly applicable here. Nonetheless, some of the Ed-munds factors obviously are helpful in our analysis”). Thus, in addition to our analysis of the plain language, we may consider, as necessary, any relevant decisional law and policy considerations argued by the parties, and any extra-jurisdictional case law from states that have identical or similar provisions, which may be helpful and persuasive. See Jubelirer, 953 A.2d at 525 n.12.

Finally, we emphasize that Article I is the Commonwealth’s Declaration of Rights, which spells out the social contract between government and the people and which is of such “general, great and essential” quality as to be ensconced as “inviolate.” Pa. Const, art. I, Preamble & § 25; see also Pa. Const, art. I, § 2 (“All power is inherent in the people, and all free governments are founded on their authority and instituted for their peace, safety and happiness.”). Although plenary, the General Assembly’s police power is not absolute, as legislative power is subject to restrictions enumerated in the Constitution and to limitations inherent in the form of government chosen by the people of this Commonwealth. See Pa. Const, art. Ill, §§ 28-32 (enumerating restrictions). Specifically, under our Constitution, the people have delegated general power to the General Assembly, with the express exception of certain fundamental rights reserved to the people in Article I of our Constitution. See Pa. Const, art. I, § 25 (“[t]o guard against transgressions of the high powers which we have delegated, we declare that everything in this article is excepted out of the general powers of government and shall forever remain inviolate.”); see generally Robinson Township, 83 A.3d at 946-48.

Thus, with this context in hand, we begin with the actual language of Article I, Section 5.

1. Language

Article I, Section 5 of the Pennsylvania Constitution, entitled “Elections,” is contained within the Pennsylvania Constitution’s “Declaration of Rights,” which, as noted above, is an enumeration of the fundamental individual human rights possessed by the people of this Commonwealth that are specifically exempted from the powers of Commonwealth government to diminish. As noted above, this section provides:

Elections shall be free and equal; and no power, civil or military, shall at any time interfere to prevent the free exercise of the right of suffrage.

Pa. Const, art. I, § 5. This clause first appeared, albeit in different form, in our Commonwealth’s first organic charter of governance adopted in 1776, 11 years before the United States .Constitution was adopted. By contrast, the United States Constitution — which furnishes no explicit protections for an individual’s electoral rights, nor sets any minimum standards for a state’s conduct.of the electoral process-does not contain, nor has it ever contained, an analogous provision. See Joshua A. Douglas, The Right to Vote Under State Constitutions, 67 Vand. L. Rev. 89, 100 (2014) (observing that “the U.S. Constitution does not grant the right to vote. It instead defines the right through a negative gloss, detailing the various reasons states cannot limit the franchise,”).

The broad text of the first clause of this provision mandates clearly and unambiguously, and in the broadest possible terms, that all elections conducted in this Commonwealth must be “free and equal.” In accordance with the plain and expansive sweep of the words “free and equal,” we view them as indicative of the framers’ intent that all aspects of the electoral process, to the greatest degree possible, be kept open and unrestricted to the voters of our Commonwealth, and, also, conducted in a manner which guarantees, to the greatest degree possible, a voter’s right to equal participation in the electoral process for the selection of his or her representatives in government. Thus, Article I, Section 6- guarantees our citizens an equal right, on par with every .other citizen, to elect their representatives. Stated another way, the. actual and plain language of Section 5 mandates that all voters have an equal opportunity to translate their votes into representation. This interpretation is consistent with both the historical reasons for the inclusion of this provision in our Commonwealth’s Constitution and the meaning we have ascribed to it through our-caselaw.

2. History

Our Commonwealth’s centuries-old and unique history has influenced the evolution of the text of the Free and Equal Elections Clause, as well as our Court’s interpretation of that provision. Although the general character of our Commonwealth during the colonial era was reflective of the fundamental desire of Pennsylvania’s founder, William Penn, that'it be a haven of tolerance and non-discrimination for adherents of various religious beliefs, the manner in which the colony was governed from its inception nevertheless excluded certain groups from participation in its official government. Roman Catholics, for example, could not hold office in the colony from 1693 to 1776, due to the requirement in the Charter of Privileges, a precursor to our Constitution in which Penn set forth the manner of governance for the colony, that every candidate for office was required to swear “that he did-not believe in the doctrine of transubstantiation, that he regarded the invocation of the Virgin Mary and the saints as superstitious and the Popish Mass as idolatrous,” J. Paul Sel-sam, The Pennsylvania Constitution of 1776, 179 (1971). Thus, although successive waves of European immigrants were attracted to the Pennsylvania colony after its founding by the promise of religious tolerance, not every group which settled in Pennsylvania was afforded the equal legal right to participate in its governance. Related thereto, the colony became divided over time by the geographical areas in which these immigrants settled, as well as their religious beliefs.

English and Quaker immigrants fleeing persecution in England were the first to arrive, and settled in the eastern part- of the colony in and around the City of Philadelphia and in Chester and Bucks Counties. German immigrants .arrived thereafter in sizable numbers and settled primarily in the central and northeastern part of the colony, and finally came a large influx of Scots-Irish Presbyterians who lived primarily in .the interior and frontier regions of the colony: first in Lancaster, York and Cumberland Counties, and then expanding westward to the areas beyond the Allegheny mountains, congregating in and near the settlement which became modern day Pittsburgh. Id. at 4-5.

These groups were divided along economic and religious- lines. The English and Quakers who engaged in extensive commerce and banking became the most wealthy and aristocratic elements in the colony. Id at 6. German immigrants reaped a comfortable living from farming, the fertile lands of their ..settlement. Rosalind Branning, Pennsylvania Constitutional Development, 10 (1960). The Scots-Irish, who, occupied the frontier regions, eked out an existence through hunting, trapping, and subsistence farming; however, they also became skilled tradesmen, highly proficient in construction, masonry, and ironworking, and began to be described as “the leather aprons,” which, although intended as a pejorative by members of the colony’s aristocracy, they proudly adopted as a badge of honor reflective of their" considerable skills and abilities in their chosen professions. Robert Brunhouse, The Counter-Revolution in Pennsylvania 1776-1790, 16 (1942).

These various groups began to align themselves into nascent political factions which, by. the 1760s, exerted varying degrees of control over the colonial government. The eastern Presbyterian adherents formed a group known as “the Proprietary Party,”, so named because- of .their faithfulness to the tenets of-William Penn’s religious and political philosophy, and they were joined by the Anglicans who had also settled in the Philadelphia region. The Quakers, disillusioned by Penn’s embrace ■of the Anglican faith, united with German pietistic religious sects to form a party known as the Quaker or “Anti-Proprietary Party.” Selsam at 6-7; Branning, at 10. .The Scots-Irish, who were angry at .having their pleas for assistance during the French and Indian War. ignored by the colonial assembly, which was dominated by the Proprietary Party, aligned with the Anti-Proprietary party as a means of achieving their goal of fair representation in the assembly. Branning at 10.

Although these political alliances remained intact until the early 1770s, they began to unravel with the tensions occasioned by the general colonial revulsion at the heavy-handed. tactics of the British Crown — e.g., the imposition of the Stamp Act and the use of writs of assistance to enforce the Revenue Act — which ultimately culminated in‘the-Revolutionary War. The Quakers and the Anglicans remained loyal to the British Crown as these tensions rose. However, the Scots-Irish in the western region, who dominated the Anti-Proprietary Party, were strongly supportive of the cause of the opponents of the crown, and they began to demand reforms be made by the colonial assembly, controlled by the Proprietary Party, including reapportionment of representation to the west. Id. at 11. They were joined in this effort by a large segment of the working-class population of the City of Philadelphia, disenfranchised by the requirement of the Charter of Privileges that imposed a property ownership requirement for the right to vote. This, coupled with the Charter’s restriction of representation in the assembly to counties,- resulted in the un-derrepresentation of the City of Philadeh phia in colonial affairs, as well as the denial of representation to the western region due to the assembly’s deliberately slow pace in recognizing new counties in that area. Id. Thus, by the early 1700s, colonial government remained dominated by the counties of Philadelphia, Chester, and Bucks, even though they had been eclipsed in population by the western regions of the colony and the City of Philadelphia. Sel-sam at 31-33. Although, in an effort to placate these groups, the assembly granted a concession by giving the west 28 seats in the assembly, while retaining 30 for the east, this did little to mollify the fervor of these groups for further reform. Branning at 11.

The opportunity for such reform arose with the formal adoption of the Declaration of Independence by the Continental Congress in 1776. This same Congress also adopted a resolution suggesting that the colonies adopt constitutions in the event that they had “no government sufficient to the exigencies of their affairs.” Id. at 12. For the Pennsylvania colony, this was the catalyst which enabled the reformers from the western regions and the City of Philadelphia, who were now known as “the radicals,” to achieve the calling of a constitutional convention. This convention, which was presided over by Benjamin Franklin, who also was serving at the same time in the Continental Congress, adopted our Commonwealth’s Constitution of 1776, which, for its time, was considered very forward thinking. Id. at 13. Many of its provisions reflected the prevailing sentiment of the radical delegates from the frontier and the City of Philadelphia for a devolution of centralized political power from the hands of a very few, in order to form a government more directly responsive to the needs of the people. Thus, it adopted a unicameral legislature on the belief that bicameral legislatures with one house dominated by elites who were elected on the basis of monetary or property qualifications would thwart the will of the people, as expressed'through their representatives in the lower chamber, whose members were elected by those whose right of' suffrage was not similarly constrained. Joseph S. Foster, The Politics of Ideology: The Pennsylvania Constitutional Convention of 1789-1790, 123 Pennsylvania J. of History, Vol. 59, No. 2 (April 1992). Even though concerned with foundational matters such as the structure of government, the delegates, in response to their experience of being excluded from participation in the colonial government, included two explicit provisions to establish protections of the right of the people to fair and equal representation in the governance of their affairs.

The first requirement was that representation be proportional to population and that reapportionment of legislative seats be done every seven years. See Pa. Const, of 1776, art. I, § IV. As noted by one commentator, this was the direct product of the personal history of the majority of the delegates, and the requirement of equal representation was, thus, intended to protect future individuals against the exclusion from the legislative process “by persons who gained power and intended to keep it.” John L. Gedid, “History of the Pennsylvania Constitution” as appearing in Ken Gormley, ed., “The Pennsylvania Constitution A Treatise on Rights and Liberties, 48 (2004).

Concomitant with this requirement, the delegates also deliberately incorporated into that Constitution the Declaration of Rights — -which they considered to be an integral part of its framework — and therein the first version of Article I, Section 5, which "declared that “all elections ought to be free; and that all free men having a sufficient evident common interest -with; and attachment to the community, have a right to elect officers, or to be elected into office.” Pa. Const, of 1776, art. I, § VII.

This section reflected the delegates’ desire to secure access to the election process by all people with an interest in the communities in which they lived — universal suffrage — by prohibiting exclusion from the election process of those without property or financial means. It, thus, established a critical “leveling” protection in an effort to establish the uniform right of the people of this Commonwealth to select their representatives in government. It sought to ensure that this right of the people would forever remain equal no matter their financial situation or social class. Gedid, at 51; see also Selsam, at 190 (“The long struggle by the people for the control of their affairs was -finally rewarded”).

Opposition to the new Constitution arose almost immediately, driven chiefly by the Quakers, Episcopalians, and Germans who had not fought in the Revolution, and the commercial interests in the City of Philadelphia. Branning at 17. These groups felt excluded from participation in the new government just as the factions who had written the 1776 Constitution previously did. Moreover, significant resentment grew over the increasing political power and attainment of elected office by those of lower socioeconomic status in the period after 1776. The social and commercial aristocracy of the Commonwealth resented the acquisition of political control of state government by the “leather aprons.” Brun-' house at 16. Further, the exclusion of some of the population through the requirement of “test oaths” in the 1776 Constitution, which required all voters, candidates for office, and office holders to swear allegiance to uphold the new frame of government, further alienated those groups, chiefly from the eastern' part of the state,' for whom such oaths violated their religious beliefs. Id. These groups united and became known as- the “Anti-Constitutionalists,” and later by the designation Republicans and, later still, Federalists. Supporters of the new charter of governance were allied into a political faction known as the Constitutionalists.

The strife between these two groups, and deficiencies in the structure of the new government — ie., the lack of a strong executive and an ill-defined role for a putative executive body created by the 1776 Constitution and given power over the legislature, the Council of Censors — rapidly intensified, such that the Commonwealth’s government became paralyzed- by dysfunction, so much so that the Continental Congress threatened to take it over. Gedid, at 52. These two factions -vied for control of the- Council of Censors and the General Assembly throughout the late 1770s and 1780s. The Republicans, though well represented on the Council of Censors, could not garner the necessary votes to call a constitutional convention under its rules. However, popular dissatisfaction with the chaotic state of the Commonwealth’s governance grew to such a degree that the Republicans gained control of the General Assembly in 1788, and, in November 1789, they passed legislation to call a constitutional convention. Branning, at 19.

Although there was some opposition to the calling of the convention by the Constitutionalists, given that the 1776 Constitution contained no explicit authorization for the assembly to do so, they, nevertheless, agreed to participate in the convention which began on November 24,1789, Rather than continuing the internecine strife that had continually threatened the new Commonwealth’s government, the leaders of the Constitutionalists, who were prominent political leaders with deep experience, serving in the Commonwealth government, such as William Findley, forged what was regarded as an unexpected alliance with powerful members of the leadership of the Republicans, particularly- James Wilson. Foster, at 128-29. The coalition of delegates shepherded by Findley and Wilson in producing a new Constitution was remarkable, given the regional and ideological strife which had preceded the convention. Its members represented 16 of the state’s 21 counties, and they came from widely divergent geographic regions of the Commonwealth,' ranging from Northampton County in the northeastern region of the state to - Allegheny and Washington counties in the west. These delegates thus represented a wide spectrum of people with diverse political, ideological, and religious .-views. Id, at 131, Their work yielded a- Constitution which, while making the structural reforms to the Commonwealths government favored by the Republicans, such as the-adoption-of a bicameral legislature and the creation of the office of chief executive with .veto power over legislation, also preserved the principle cherished most by the .Constitutionalists — namely, popular elections in which the people’s right .to elect their representatives in gov-, ernment would be equally available to all, and would, hereinafter, not be intentionally diminished by laws that discriminated against a voter based on his social or economic status, geography of his residence, or his religious and political beliefs. Id. at 137-38. ■

Consequently, popular election of representatives was maintained by the new Constitution, and applicable in all elections for both houses of the bicameral legislature. Importantly, consistent with the evident desire of the delegates.to neutralize the factors which had formerly given rise to such rancorous division amongst the people in the selection of their representatives, the language, of Article I, Section 5 was revised to remove all prior ambiguous qualifying language. In its place, the delegates adopted the present language of the first clause of Article I, Section 5, which has remained unchanged to this day by the people of this Commonwealth. It states, simply and plainly, that “elections shall be free and equal.”

When viewed against the backdrop of the intense and seemingly unending regional, ideological, and sectarian strife detailed above, - which bitterly divided the people of various regions of our state, this provision must be -understood then as a salutary effort by the learned delegates to the 1790 convention to end, once and for all, the primary cause of popular dissatisfaction which undermined the governance of Pennsylvania: namely, the dilution of the right of the people of this Commonwealth to select representatives to govern their affairs based on considerations of the region of the state in which they lived, and the religious and political béliefs to which they adhered. These historical motivations of the framers have undergirded our Court’s interpretation of the Free and Equal Elections Clause throughout the years since its inclusion in our Constitution.

3. Pennsylvania Case Law

As one noted commentator on the Pennsylvania Constitution, Charles Buckalew, himself a delegate to the 1873 Constitutional Convention, opined, given the aforementioned history, the words “free and equal” as used in Article I, Section 5 have a broad and wide sweep:

They strike not only at privacy and partiality in popular elections, but also at corruption, compulsion, and other undue influences by which elections may be assailed; at all regulations of law which shall impair the right of suffrage rather than facilitate or reasonably direct the manner of its exercise, and at all its limitations, unproclaimed by the Constitution, upon the eligibility of the electors for office. And they exclude not only all invidious discriminations between individual electors, or classes of electors, but also between different sections or places in the State.

Charles R. Buckalew, An Examination of the Constitution of Pennsylvania. Exhibiting The Derivation and History of Its Several Provisions, Article I at 10 (1883).

Our Court has ascribed the same expansive meaning to the terms “free and equal” in Article I, Section 5. Although our Court has infrequently relied on this provision to strike down acts of the legislature pertaining to the conduct of elections, the qualifications of voters to participate therein, or the creation-of electoral districts, our view as to what constraints Article I, Section 5 places on the legislature in these areas has been consistent over the years. Indeed, nearly 150 years ago, in considering a challenge to an act of the legislature establishing eligibility qualifications for electors to vote in all elections held in Philadelphia, and specifying the manner in which those elections are to be conducted, we recognized that, while our Constitution gives to the General Assembly the power to promulgate laws governing elections, those enactments .are nonetheless subject to the requirements of the Free and Equal Elections' Clause of ■ our Constitution, and, hence, may be invalidated by our Court “in a case of plain; palpable and clear abuse of the power which actually infringes ■ the rights of the electors,” Patterson, 60 Pa. at 75.

In answering the question of how elections must ]oe made equal, we stated: “Clearly by laws which shall arrange all the-qualified electors into 'suitable districts, and make their votes equally potent in the election; so that some shall not have more votes than others, and that all shall have an equal share in filling the offices of the Commonwealth.” Id. Thus, with this decision, our Court established that 'any legislative scheme'which has the effect'of impermissibly diluting, the potency of ’an individual’s vote for candidates for elective office .relative to. that of other voters will violate the guarantee of “free and equal” elections- afforded by Article I, Section 5. See City of Bethlehem, 515 A.2d at 1323-24 (recognizing that a legislative enactment which “dilutes the vote of any segment of the constituency” will violate Article I, Section 5). .This interpretation is wholly consonant with the intent of the framers of the 1790 Constitution to ensure that each voter will have an equally effective power to select the represéntative of his or. her choice, free from any discrimination on the basis of his or her particular beliefs or views.

In the nearly 150. year a since Patterson, our Court has not retreated from, this interpretation of the Free and Equal Elections Clause. In 1914, our Court, in the case of Winston, supra, considered a challenge under the Free and Equal Elections Clause to an .act of the legislature which set standards regulating the nominations and elections for judges and elective offices in the City of Philadelphia. Although our Court ultimately ruled that the act did not violate this clause, we again reaffirmed that the clause protected a voter’s individual right to an equal, nondiscriminatory electoral process. In describing the minimum requirements for “free and fair” elections, we stated:

[Ejections are free and equal within the meaning of the Constitution when they are public and open to . all qualified electors alike; when every voter has the same right as every other voter; when each voter under the law has the right to cast his ballot and have it honestly counted; when the .regulation of the right to exercise the franchise does not deny the franchise itself, or make it so difficult as to amount to a denial; and when no constitutional right of the qualified elector is subverted or denied him.

Winston, 91 A. at 523.

We relied on these principles in the case of In re New Britain Borough School District, 295 Pa. 478, 145 A. 597 (1929), to strike down the legislative creation of voting districts for elective office which, although not overtly depriving electors therein of their right to choose candidates for office secured by the Free and Equal Elections Clause, nevertheless operated to impair that right. In that case, the legislature created a new borough from parts of two existing townships and created a school district which overlapped the boundaries of the new borough. The new district, thus, encompassed part of the school district in each of the townships from which it was created. Pursuant to other acts of the legislature then in force, the court of common pleas of the county in which the district was situated, upon petition of taxpayers and electors in the newly created borough, appointed a board of school directors. The creation of the new school district was ultimately not approved as required by other legislation mandating the assent of the state board of elections for the creation of the district, and, thus, technically the residents of the new borough remained within their old school districts.

Residents of each of the former townships challenged the constitutionality of the effect of the combination of their former respective school districts under the Free and Equal Elections Clause, arguing that they had been deprived of their right to select school directors. Our Court agreed, and found that the residents of the two formér school districts were effectively denied their right to elect representatives of their choosing to represent them on a body which would decide how their tax monies were spent. We noted that the residents of the newly created school district could not lawfully vote for representatives on the school boards of their prior districts, given that they were no longer legally residents thereof, and they also could not lawfully vote for school directors in the newly created school district, given that the ballot for every voter was required to be the same, and, because the new school district had not been approved, the two groups of borough residents would each have to be given separate ballots for their former districts. In our discussion of the Free and Equal Elections Clause, our Court emphasized that the rights protected by this provision may not be taken away by an act of the legislature, and that that body is prohibited by this clause from interfering with the exercise of those rights, even if the interference occurs by inadvertence. Id. at 599.

While it is true that our Court has not heretofore held that a redistricting plan violates the Free and Equal Elections Clause — for example, because it is the product of politically-motivated gerrymandering — -we have never precluded such a claim in our jurisprudence. Our Court considered a challenge under Article I, Section 5 rooted in alleged political gerrymandering in the creation of state legislative districts in In re 1991 Pennsylvania Legislative Reapportionment Comm’n, supra. In that case, we entertained and rejected a claim that political gerrymandering operated to deny a candidate’s claimed right to run for state legislative office under this provision. We found that the individual’s constitutionally protected right to run for state legislative office was protected by the redistricting plan, but concluded that right did not extend so far as to require that a reapportionment plan be tailored to allow him to challenge the incumbent of his choice.

More saliently, in Erfer, our Court specifically held that challenges to the enactment of a congressional redistricting plan predicated on claims of impermissible political gerrymandering may be brought under Article I, Section 5. Therein, we rebuffed the argument that Article I, Section 5 was limited in its scope of application to only elections of Commonwealth officials, inasmuch as there was nothing in the plain text of this provision which would so limit it. Likewise, our own review of the historical circumstances surrounding its inclusion in the 1790 Constitution, discussed above, supports our interpretation.

Moreover, in Erfer, we rejected the argument, advanced by Legislative Respondents in their post-argument filing seeking a stay of our Court’s order of January 22, 2018, that, because Article I, Section 4 of the United States Constitution confers on state legislatures the power to enact congressional redistricting plans, such plans are not subject to the requirements of the Pennsylvania Constitution:

It is true that the U.S. Constitution has granted our legislature the power to craft congressional reapportionment plans. Yet, we see no indication that such a grant of power simultaneously suspended the constitution of our Commonwealth vis & vis congressional reapportionment. Without clear support for the radical conclusion that our Commonwealth’s Constitution is nullified in challenges to congressional reapportionment plans, it would be highly inappropriate for us to circumscribe the operation of the organic legal document of our Commonwealth.

Id. at 331.

Ultimately, in Erfer, we did not opine on whether, under our prior decisions interpreting Article I, Section 5, a congressional redistricting plan would be, violative of the Free and Equal Elections Clause because of political gerrymandering. Although the petitioners in that case alleged that the redistrieting plan at issue therein violated Article I, Section 5, our Court determined' that they had not provided sufficient reasons for us to interpret -our constitutional provision as furnishing additional protections of the right to vote beyond those recognized by the United States Supreme Court as conferred by the Equal Protection Clause of the United States Constitution. See id. at 332 (“Petitioners provide us with no persuasive argument as 'to why we should, at this juncture, interpret our constitution in such a fashion that the right to vote is more expansive than the guarantee found in the federal constitution.”). Thus, we adjudicated the Article I, Section 5 challenge in that case solely on federal equal protection grounds, and rejected it, based on the test for such claims articulated by the plurality of the United States Supreme Court in Bandemer, supra.

Importantly, however, our Court in Er-fer did not foreclose future challenges under Article I, Section 5 resting solely on independent state grounds. Indeed, the unique historical reasons discussed above, which were the genesis of Article I, Section 5, and its straightforward directive that “elections shall be free and equal” suggests such a separate analysis is warranted. The Free and Equal Elections Clause was specifically intended to equalize the power of voters in our Commonwealth’s election process, and it explicitly confers this guarantee; by contrast, the Equal Protection Clause was added to the United States Constitution 78 years later with the ratification of the Fourteenth Amendment to address manifest legal inequities which were contributing causes of the Civil War, and which persisted in its aftermath, and it contains no such unambiguous protections.

Moreover, and importantly, when properly presented with the argument, our Court entertains as distinct claims brought under the Free, and Equal Elections Clause of our Constitution and the federal Equal, Protection Clause, and we adjudicate them separately, utilizing the relevant Pennsylvania and federal standards. In Shankey v. Staisey, 436 Pa. 65, 257 A.2d 897 (1969), a group of third-party voters challenged a Pennsylvania election statute which specified that, in order for an individual’s vote for a third-party candidate for a particular office in the primary election to be counted, the total number of aggregate votes by third-party voters for that office had to equal or exceed the number of signatures required on a nominating petition to be listed on the ballot as a candidate for that office. The voters’ challenge, which was brought under both the Free and Equal Elections Clause of the Pennsylvania Constitution and the Equal Protection Clause of the United States Constitution, alleged that these requirements wrongfully equated public petitions with ballots, thereby imposing a more stringent standard' for their vote to be counted than that which voters casting ballots for major party candidates had to meet.

Our Court applied different constitutional standards in deciding these claims. In considering and rejecting the Article I, Section 5 claim — that the third-party candidates’ right to vote was diminished because of these special requirements — our Court applied the interpretation of the Free and Equal Elections Clause set forth in Winston, supra, and ruled that, because the statute required major party candidates and third party candidates to demonstrate the same numerical level of voter support for their votes to be counted, the fact thát this demonstration was made by ballot as opposed" to by petition did not render the election process unequal. By contrast, in adjudicating the equal protection claim, our Court utilized the test for an equal protection clause violation articulated by the'United States Supreme Court and examined whether the statute served to impermissibly classify voters without a reasonable basis to do so.

Given the nature of the petitioners’ argument in E-rfer, which was founded on their apparent belief that the protections of Article I, Section 5 and Article 1, Section 26 were coextensive, our Court was not called upon, therein, to reassess the validity of the Shankey Court’s use of a separate and distinct standard for adjudicating a claim that a particular legislative enactment involving the electoral process violates the Free and Equal Elections Clause, from that used to determine if the enactment violates the federal Equal Protection Clause. Thus, we reject Justice Mundos assertion that Erfer requires us, under the principles of stare decisis, to utilize the same standard to adjudicate a claim of violation of the Free and Equal Elections Clause and the federal Equal Protection Clause. See Dissenting Opinion (Mundy, J.) at 834-35. To the extent that Erfer can be read for that proposition, we expressly disavow it, and presently reaffirm that, in accord with Sharkey and the particular history of the Free and Equal Elections Clause, recounted above, the two distinct claims remain subject to entirely separate jurisprudential considerations.

4. Other Considerations

In addition to the occasion for the adoption of the Free and Equal Elections Clause, the circumstances in which the provision was adopted, the mischief to be remedied, and the object to be obtained, as described above, the consequences of a particular interpretation are also relevant in our analysis. Specifically, partisan gerrymandering dilutes the votes of those who in prior elections voted for the party not in power to give the party in power a lasting electoral advantage. By placing voters preferring one party’s candidates in districts where their votes are wasted on candidates likely to lose (cracking), or by placing such voters in districts where their votes are cast for candidates destined to win (packing), the non-favored party’s votes are diluted. It is axiomatic that a diluted vote is not an equal vote, as all voters do not have an equal opportunity to translate their votes into representation. This is the antithesis of a healthy representative democracy. Indeed, for our form of government to operate as intended, each and every Pennsylvania voter must have the same free and equal opportunity to select his or her representatives. As our foregoing discussion has illustrated, our Commonwealth’s commitment to neutralizing factors which unfairly impede or dilute individuals’ rights to select their representatives was borne of our forebears’ bitter personal experience suffering the pernicious effects resulting from previous electoral schemes that sanctioned such discrimination. Furthermore, adoption of a broad interpretation guards against the risk of unfairly rendering votes nugatory, artificially entrenching representative power, and discouraging voters from participating in the electoral process because they have come to believe that the power of their individual vote has been diminished to the point that it “does not count.” A broad and robust interpretation of Article I, Section 5 serves as a bulwark against the adverse consequences of partisan gerrymandering.

5. Conclusion

The above analysis of the Free and Equal Elections Clause — its plain language, its history, the occasion for the provision and the circumstances in which it was adopted, the case law interpreting this clause, and consideration of the consequences of our interpretation — leads us to conclude the Clause should be given the broadest interpretation, one which governs all aspects of the electoral process, and which provides the people of this Commonwealth an equally effective power to select the representative of his or her choice, and bars the dilution of the people’s power to do so.

B. Measurement of Compliance with Article I, Section 5

We turn now to the question of what measures should be utilized to assess a dilution claim under the Free and Equal Elections Clause of the Pennsylvania Constitution. Neither Article I, Section 5, nor any other provision of our Constitution,articulates explicit standards which are to be used in the creation of congressional districts. However, since the inclusion of the Free and Equal Elections Clause in our Constitution in 1790, certain neutral criteria have, as a general matter, been traditionally utilized to guide the formation of our Commonwealth’s legislative districts in order to prevent the dilution of an individual’s vote for a representative in the General Assembly. These standards place the greatest emphasis on creating representational districts that both maintain the geographical and social cohesion of the communities in which people live and conduct the majority of their day-to-day affairs, and accord equal weight to the votes of residents in each of the various districts in determining the ultimate composition of the state legislature.

Significantly, the framers of the 1790 constitution who authored the Free and Equal Elections Clause also included a mandatory requirement therein for the legislature’s formation of state senatorial districts covering multiple counties, namely that the counties must adjoin one another. Also, the architects of that charter expressly prohibited the division of any county of the Commonwealth, or the City of Philadelphia, in the formation of such districts. Pa. Const, of 1776, § 7. Thus, as preventing the dilution of an individual’s vote was of paramount concern to that august group, it is evident that they considered maintaining the geographical contiguity of political subdivisions, and barring the splitting thereof in the process of creating legislative districts, to afford important safeguards against that pernicious prospect.

In the eight-plus decades after the 1790 Constitution became our Commonwealth’s fundamental plan of governance, many problems arose from the corruption of the political process by well-heeled special interest groups who rendered our representative democracy deeply dysfunctional by weakening the power of an individual’s vote through, inter alia, their selection, and financial backing in the electoral process, of representatives who exclusively served their narrow interests and not those of the people as a whole. Gedid, supra, at 61-63. One of the methods by which the electoral process was manipulated by these interest groups to attain those objectives was the practice of gerrymandering, popular revulsion of which became one of the driving factors behind the populace’s demand for the calling of the 1873 Constitutional Convention.

As noted by an eminent authority on Pennsylvania constitutional law, by the time of that convention, gerrymandering was regarded as “one of the most flagrant evils and scandals of the time, involving notorious wrong to the people and open disgrace to republican institutions.” Thomas Raeburn White, Commentaries on the Constitution of Pennsylvania 61 (1907). Although the delegates to that convention did not completely eliminate this practice through the charter of governance which they adopted, and which the voters subsequently approved, they nevertheless included significant protections against its occurrence through the explicit adoption of certain requirements which all state legislative districts were, thereafter, required to meet: (1) the population of such districts must be equal, to the extent possible; (2) the district that is created must be comprised of compact and contiguous geographical territory; and (3) the district respects the boundaries of existing political subdivisions contained therein, such that the district divides as few of those subdivisions as'possible. Pa. Const, of 1874, art. 2, § 16. Given the great concern of the delegates over the practice of gerrymandering occasioned by their recognition of the corrosive effects on our entire democratic process through the deliberate dilution of our citizenry’s individual votes, the focus on these neutral factors must be viewed, then, as part of a broader effort by the delegates to that convention to establish “the best methods of representation to secure a just expression of the popular will.” Branning at 59 (quoting Wayne Mac Veach, Debates of the Convention to Amend the Constitution of Pennsylvania, Volume I at 45 (1873)). Consequently, these factors have broader applicability beyond setting standards for the drawing of electoral districts for state legislative office.

The utility of these requirements to prevent vote dilution through gerrymandering retains continuing vitality, as evidenced by our present Constitution, adopted in 1968. In that charter, these basic requirements for the creation of senatorial districts were not only retained, but, indeed, were expanded by the voters to govern the establishment of election districts for the selection of their representatives in the state House of Representatives. Pa. Const., art. 2, §16;

Because these factors are deeply rooted in the organic law of our Commonwealth, and continue to be the foundational requirements which state legislative districts must meet under the Pennsylvania Constitution, we find these neutral benchmarks to be particularly suitable as a measure in assessing whether a congressional districting plan dilutes the potency of an individual's ability to select the congressional representative of his or her choice, and thereby violates the Free and Equal Elections Clause. In our judgment, they are wholly consistent with the overarching intent of the framers of the 1790 Constitution that an individual’s electoral power not be diminished through any law which discriminatorily dilutes the power of his or her vote, and, thus, they are a measure by which to assess whether .the guarantee to our citizenry of “free and equal” elections; promised by Article, I Section 5 in the selection of their congressional representative has been violated. Because the character of these factors is fundamentally impartial in nature, their utilization reduces the likelihood of the creation of congressional districts which confer on any voter an unequal advantage by giving his or her vote greater weight in the-selection of a congressional representative as prohibited by Article I, Section 5. Thus, use of these objective factors substantially reduces the risk that a voter in a. particular congressional district will unfairly suffer the dilution of the power of his or her vote.

Moreover, rather than impermissibly lessening the power of an individual’s vote-based on the geographical area .-in which the individual resides — which, as explained above, Article I, Section 5 also prohibits— the use of compactness, contiguity, and the maintenance of the integrity of the boundaries of political subdivisions maintains the strength of an individual’s vote in electing a congressional representative. When an individual is grouped with other members of his or her community in a congressional district for purposes of voting, the commonality of the interests shared with the other voters in the community increases the ability of the individual to elect a congressional representative for the district who reflects his or her personal preferences. This approach inures to no political party’s benefit or detriment. It simply achieves the constitutional goal of fair and equal elections for all of our Commonwealth’s voters. Finally, these standards also comport, with the minimum requirements for congressional districts guaranteed .by the United States Constitution, as interpreted by the United States Supreme Court, See Wesberry v. Sanders, 376 U.S. 1, 18, 84 S.Ct. 526, 11 L.Ed.2d 481 (1964) (holding that, the plain objective of the United. States Constitution is to make “equal representation for equal numbers of people the fundamental goal for the House of Representatives.”).

Consequently, for all of these reasons, and as expressly set forth in our Order of January 22, 2018, we adopt these measures as appropriate in determining whether a congressional redistricting plan violates the Free arid Equal Elections Clause of the Pennsylvania Constitution. Therefore, an essential part of such an inquiry is an examination of whether the congressional districts created under a redistricting plan are:

composed of compact and contiguous territory; as nearly equal in population as practicable; and which do not divide any county, city, incorporated town, borough, township, or ward, except where necessary to ensure equality of population.

Order, 1/22/19, at ¶ “Fourth.”

'We recognize that other factors have historically played a role in the drawing of legislative districts, such as the preservation of prior district lines, protection of incumbents, or the maintenance of the political balance' which existed after the prior reapportionment. See, e.g., Holt I, 38 A.3d at 1235. However, we view these factors to be wholly subordinate to the neutral criteria of compactness, contiguity, minimization of the division of political subdivisions,. and maintenance of population equality among congressional districts. These neutral criteria provide a “floor” of protection for an individual against the dilution of his or her vote in the creation of such districts.

When, however, it is demonstrated that, in the creation of congressional districts, these neutral criteria have been subordinated, in whole or in part, to extraneous considerations such as gerrymandering for unfair partisan political advantage, a congressional redistricting plan violates Article I, Section 5 of the Pennsylvania Constitution. We note that, consistent with our prior interpretation of Article I, Section 5, see In re New Britain Borough School District, supra, this standard does not require a showing that the creators of congressional districts intentionally subordinated these traditional criteria to other considerations in the creation of the district in order for it to violate Article I, Section 5; rather, it is sufficient to, establish a violation of this section to show .that these traditional criteria were subordinated to. other factors.

However, this is not the exclusive means by which a violation of Article I, Section 5 may be established. As we have repeatedly emphasized throughout our discussion, the overarching objective of this provision of our constitution is to prevent dilution of an individual’s vote by mandating that the power of his or her vote in the selection of representatives be equalized to the greatest degree possible with all other Pennsylvania citizens. We recognize, then, that there exists the possibility that advances in map drawing technology and analytical software can potentially allow maprtiakers, in the future, to engineer congressional districting maps, which, although minimally comporting with these neutral “floor” criteria, nevertheless operate to unfairly dilute the power of a particular group’s vote for a congressional representative. See Ñ.T. Trial, 12/13/17, at 839-42 '(Dr. Warshaw discussing the concept of an efficiency gap based on the number of “wasted” votes for the minority political party under a particular redistricting plan). However, as the case at bar may be resolved solely on the basis of consideration of the degree to which neutral criteria were subordinated to the pursuit of partisan political advantage, as discussed below) we need not address at this juncture the possibility of such future claims.'

We are confident, however, that, technology can also be employed to aid in the expeditious development of districting maps, the boundaries of which are drawn to scrupulously adhere to neutral criteria. Indeed, as this Court highlighted in Holt I, “the development of computer technology appears to have substantially allayed the initial, extraordinary difficulties in” meeting such criteria. Holt I, 38 A.3d at 760; see also id. at 750 (noting that, since 1991, technology has provided tools allowing mapmakers to “achieve increasingly ‘ideal’ districts”) (citing Gormley, Legislative Reapportionment, at 26-27, 45-47); see also Larios v. Cox, 305 F.Supp.2d 1335, 1342 (N.D. Ga. 2004) (“given recent advances in computer technology, constitutional plans can be crafted in as short a period as one day”). As this Court views the record in this case,, in the context of the computer technology of 2018, this thesis has clearly been proven.

C. Application to the 2011 Plan

Having established the means by which we measure a violation of Article I, Section 5, we now apply that measure to the 2011 Plan. Doing so, it is clear, plain, and palpable that the 2011 Plan subordinates the traditional redistricting criteria in the service of partisan advantage, and thereby deprives Petitioners of their state constitutional right to free and equal elections. See West Mifflin Area School District, 4 A.3d at 1048. Indeed, the compelling expert statistical evidence presented before the Commonwealth Court, in combination with and illustrated by an examination of the Plan itself and the remainder of the evidence presented below, demonstrates that the Plan cannot plausibly be directed at drawing equally populous, compact, and contiguous districts which divide political subdivisions only as necessary to ensure equal population.

Perhaps the most compelling evidence concerning the 2011 Plan derives from Dr. Chen’s expert testimony. As detailed above, Dr. Chen created two sets of 500 computer-simulated Pennsylvania redistricting plans, the first of which — Simulated Set 1 — employed the traditional redistricting criteria of population equality, compactness, contiguousness, and political-subdivision integrity — ie., a simulation of the potential range of redistricting plans attempting to apply the traditional redistricting criteria. Dr. Chen’s Simulated Set 1 plans achieved population equality and contiguity; had a range of Reock Compactness Scores from approximately .31 to .46, which was significantly more compact than the 2011 Plan’s score of .278; and had a range of Popper-Polsby Compactness Scores from approximately .29 to .35, which was significantly more compact than the 2011 Plan’s score of .164. Further, his simulated plans generally split between 12-14 counties and 40-58 municipalities, in sharp contrast to the 2011 Plan’s far greater 28 county splits and 68 municipality splits. In other words, all of Dr. Chen’s Simulated Set 1 plans, which were, again, a simulation of the potential range of redistricting plans attempting to apply the traditional redistricting criteria, were more compact and split fewer political subdivisions than the 2011 Plan, establishing that a process satisfying these traditional crite-lia would not lead to the 2011 Plan’s adoption. Thus, Dr. Chen unsurprisingly opined that the 2011 Plan subordinated the goals of compactness and political-subdivision integrity to other considerations. Dr. Chen’s testimony in this regard establishes that the 2011 Plan did not primarily consider, much less endeavor to satisfy, the traditional redistricting criteria.

Dr. Chen’s testimony in this regard comports with a lay examination of the Plan, which reveals tortuously' drawn districts that cause plainly unnecessary political-subdivision splits. In terms of compactness, a rudimentary review reveals a map comprised of oddly shaped, sprawling districts which wander seemingly arbitrarily across Pennsylvania, leaving 28 counties, 68 political subdivisions, and numerous wards, divided among as many as five congressional districts, in their wakes. Significantly, these districts often rend municipalities from their surrounding metropolitan areas and quizzically divide small municipalities which could easily be incorporated into single districts without detriment to the traditional redistricting criteria. As Dr. Kennedy explained below, the 7th Congressional District, pictured above, has been referred to as resembling “Goofy kicking Donald Duck,” and is perhaps chief among a number of rivals in this regard, ambling from Philadelphia’s suburbs in central Montgomery County, where it borders four other districts, south into Delaware County, where it abuts a fifth, then west into Chester County, where it abuts another district and travels northwest before jutting out in both northerly and southerly directions into Berks and Lancaster Counties. Indeed, it is difficult to imagine how a district as Rorschachian and sprawling, which’is contiguous in two-locations only by virtue of a medical facility and a seafood/steakhouse, respectively, might plausibly be referred to as “compact.” Moreover, in terms of political subdivision splits, the 7th Congressional District splits each of the five counties in its path and some 26 separate political subdivisions between multiple congressional districts. In other words, the 7th Congressional District is itself responsible for 17% of the 2011 Plan’s county splits and 38% of its municipality splits.

The 7th Congressional District, however, is merely the starkest example of the 2011 Plan’s overall composition. As pictured above, and as discussed below, many of the 2011 Plan’s congressional districts similarly sprawl through Pennsylvania’s landscape, often contain “isthmuses” and “tentacles,” and almost entirely ignore the integrity of political subdivisions in their trajectories. Although the 2011 Plan’s odd shapes and seemingly arbitrary political subdivision splits are not themselves sufficient to conclude it is not predicated on the traditional redistricting factors, Dr. Chen’s cogent analysis, confirms that these anomalous shapes are neither necessary to, nor within the ordinary range of, plans generated with solicitude toward applying traditional redistricting considerations.

The fact that the 2011 Plan cannot, as a statistical matter, be a plan directed .at complying with traditional redistricting requirements is sufficient to establish that it violates the Free and Equal Elections Clause. Nevertheless, we acknowledge the multitude of evidence introduced in the Commonwealth Court showing that its deviation from’these traditional requirements was in service of, and effectively works to, the unfair partisan advantage of Republican candidates ’ in future - congressional elections and, conversely, dilutes Petitioners’ power to vote for congressional representatives who represent their views. Dr. Chen explained that, while his simulated plans created a range of up to 10 safe Republican districts with a mean-median vote gap of 0 to 4%, the 2011 Plan creates 13 safe Republican districts with a mean-median vote gap of 5.9%. Dr. Chen also credibly rejected the notion that the 2011 Plan’s outlier status in this regard was attributable to an attempt to account for Pennsylvania’s political geography, to protect incumbent congresspersons, or to establish the 2011 Plan’s majority-African American district. Indeed, he explicitly concluded that the traditional redistricting criteria were jettisoned in favor of unfair partisan gain. Dr. Warshaw’s testimony similarly detailed how the 2011 Plan not only preserves the modest natural advantage, or vote efficiency gap, in favor of Republican congressional candidates relative to Republicans’ statewide vote share— which owes to the fact that historically Democratic voters tend to self-sort into metropolitan areas and which he testified, until the 2011 Plan, was “never far from zero” percent — but also ' creates’ districts that increase that advantage to between 15 to 24% relative to statewide vote share. In other words, in its disregard of the traditional redistricting factors, the 2011 Plan consistently works toward and accomplishes the concentration of the power of historically-Republiean voters and, conversely, the corresponding dilution of Petitioners’ power to elect'their chosen representatives.

Indeed, these statistical analyses are illustrated to some degree by .Dr. Kennedy’s discussion of the 2011 Plan’s particulars. Dr. Kennedy, for example, explained that, at the district-by-district level, the 2011 Plan’s geospatial oddities and divisions of political subdivisions and their wards effectively serve to establish a.few overwhelmingly Democratic districts and a large majority of less strong, but nevertheless likely Republican districts. For example, the 1st Congressional District, beginning in Northeast Philadelphia and largely tracking the Delaware River, occasionally reaches “tentacles” inland, incorporating Chester, Swarthmore, and other historically Democratic regions. Contrariwise, although.the 3rd Congressional District formerly contained traditionally-Democratic Erie County in its entirety, the 2011 Plan’s 3rd and 5th Congressional Districts now divide that constituency, making both districts likely to elect Republican candidates. Additionally, it is notable that the 2011 Plan’s accommodation for Pennsylvania’s loss ■ of one congressional seat took the form of redrawing its 12th Congressional District, a 120-mile-long district that abuts four others and pitted two Democratic incumbent congressmen against one another in the next cycle’s primary election, after which the victor of that contest lost to a Republican candidate who gleaned 51.2% of the general election vote. These geographic idiosyncrasies, the evidentiary record shows, served to strengthen the votes of voters inclined to vote for Republicans in congressional races and weaken those inclined to vote for Democrats.

In sum, we conclude that the evidence detailed above and the remaining evidence of the record as a whole demonstrates that Petitioners have established that the 2011 Plan subordinates the traditional redistricting criteria in service of achieving unfair partisan advantage, and, thus, violates the Free and Equal • Elections Clause of the Pennsylvania Constitution. Such a plan, aimed at achieving unfair partisan gain, undermines voters’ ability to exercise their right to vote in free and “equal” elections if the term is to be interpreted in any credible way.

An election corrupted by extensive, sophisticated gerrymandering and partisan dilution of votes is not “free and equal.” In such circumstances, a “power, civil or military,” to wit, the General Assembly, has in fact “interfere[d] to prevent the free exercise of the right of suffrage.” Pa. Const, art. 1, § 5.

VI. Remedy

Having set forth why the 2011 Plan is constitutionally infirm, we turn to our January 22, 2018 Order which directed a remedy for the illegal plan. Therein, our Court initially invited our sister branches — the legislative and executive branches — to take action, through the enactment of a remedial congressional districting plan; however, recognizing the possibility that the legislature and executive would be unwilling or unable to act, we indicated in our. Order that, in that eventuality, .we would fashion a-judicial remedial plan:

Second, should the Pennsylvania General Assembly choose to submit a congressional districting plan that satisfies the requirements of the Pennsylvania Constitution, it shall submit such plan for consideration by the Governor on or before February 9, 2018; If the Governor accepts the General Assembly’s congressional. districting plan, it shall be submitted to this Court on or before February 15, 2018.
Third, should the General'Assembly not submit a congressional districting plan on or before February 9, 2018, or should the Governor not approve the General Assembly’s plan on or before February 15, 2018, this Court shall proceed expeditiously to adopt a plan based on the evidentiary recorcf developed in the Commonwealth Court. In anticipation of that eventuality, ,the parties shall have the opportunity to be. heard; to wit, all parties and intervenors may submit to, the Court proposed remedial district-ing plans on or before February 15, 2018.

Order, 1/22/18, at ¶¶ “Second” and “Third.”

As to the initial and preferred path of legislative and executive action, we note that the primary responsibility and authority for drawing federal congressional legislative districts rests squarely with the state legislature. See U.S. Const, art. I, § 4; Butcher, 216 A.2d at 458 (“[W]e considered it appropriate that the Legislature, the organ of government with the primary responsibility for the task of reappprtionment, be afforded an additional opportunity to enact a constitutional reapportionment plan.”); Growe v. Emison, 507 U.S. 25, 34, 113 S.Ct. 1075, 122 L.Ed.2d 388 (1993) (stating that “the Constitution leaves with the States primary responsibility for apportionment of their federal congressional and state legislative districts”); Wise v. Lipscomb, 437 U.S. 535, 539, 98 S.Ct. 2493, 57 L.Ed.2d 411 (1978); Reynolds, 377 U.S. at 586, 84 S.Ct. 1362. Thus, in recognizing this foundational tenet, but also considering both the constitutionally infirm districting plan and the imminent approaching primary elections for 2018, we requested that these sister branches enact legislation regarding a new districting plan, providing a deadline to do so approximately three weeks from the date of our Order. Indeed, if the legislature and executive timely enact a remedial plan and submit it to our Court, our role in this matter concludes, unless and until the constitutionality of the new plan is challenged.

When, however, the legislature is unable or chooses not to act, it becomes the judiciary’s role to determine the appropriate redistricting plan. Specifically, while statutes are cloaked with' the presumption of constitutionality, it is the duty of this Court, as a co-equal branch of government, to declare, when appropriate, certain acts unconstitutional. Indeed, matters concerning the proper interpretation and application of our Commonwealth’s organic charter are at the end of the day for this Court — and only this Court. Pap’s II, 812 A.2d at 611 (noting Supreme Court has final word on meaning of Pennsylvania Constitution). Further, our Court possesses broad authority to craft meaningful remedies when required. Pa. Const. art. V, §§ 1, 2, 10;. 42 Pa.C.S. § 726 (granting power to “enter a final order or otherwise cause right and justice to be done”).

Thus, as an alternative to the preferable legislative route for creating a remedial redistricting plan, in our Order, we considered the possibility that the legislature and Governor would not agree upon legislation providing for a remedial plan, and, thus, we allowed for the prospect of a judicially-imposed remedial plan. Our narrowly crafted contingency, which afforded all parties and Intervenors a full and fair opportunity to submit proposed remedial plans for our consideration, was well with-iil our judicial authority, and supported by ■not only our Constitution and statutes as noted above, but by Commonwealth and federal precedent, as well as similar remedies provided by the high courts of other states acting when their sister branches fail to remedy an unconstitutional plan.

Perhaps the clearest balancing of the legislature’s primary role in districting against the court’s ultimate obligation .to ensure a constitutional plan was set forth in our decision in Butcher. In that matter, our Court, after concluding a constitutionally infirm redistricting of both houses of the General Assembly resulted in an impairment of our citizens’ right to vote, found it prudent to allow the legislature an additional opportunity to enact a legal remedial plan. Butcher, 216 A.2d at 457-58. Yet, we also made clear that a failure to act by the General Assembly by a date certain would result in judicial action “to ensure that the individual voters of this Commonwealth are afforded their constitutional right to cast an equally weighted vote.” Id. at 458-59. After the deadline passed without enactment of the required statute, we fashioned affirmative relief, after the submission of proposals by the parties. Id. at 459. Our Order in this matter, cited above, is entirely consistent with our remedy in Butcher. See also Mellow v. Mitchell, 530 Pa. 44, 607 A.2d 204, 205-06 (1992) (designating master in wake of legislative failure to remedy redistricting of seats for the Pennsylvania House of Representatives which was held to be unconstitutional).

Our approach is also buttressed by, and entirely consistent with, the United States Supreme Court’s landmark ruling in Baker v. Carr, 369 U.S. 186, 82 S.Ct. 691, 7 L.Ed.2d 663 (1962), and more recent decisions from the United States Supreme Court which make concrete the state judiciary’s ability to formulate a redistricting plan, when necessary. See, e.g., Growe; Scott v. Germano, 381 U.S. 407, 85 S.Ct. 1525, 14 L.Ed.2d 477 (1965) (per curiam). As described by the high Court in Wise, “Legislative bodies should not leave their reapportionment tasks to the federal courts; but when those with legislative responsibilities do not respond, or the imminence of a state election makes it impractical for them to do so, it becomes the ‘unwelcome obligation,’ Connor v. Finch, [ 431 U.S. 407, 415, 97 S.Ct. 1828, 52 L.Ed.2d 465 (1977) ], of the federal court to devise and impose a reapportionment plan pending later legislative action.” Wise, 437 U.S. at 540, 98 S.Ct. 2493. The same authority to act is inherent in the state judiciary.

Specifically, in Growe, the United States Supreme Court was faced with the issue of concurrent jurisdiction between a federal district court and the Minnesota judiciary regarding Minnesota’s state legislative and federal congressional districts. The high Court, in a unanimous decision authored by Justice Scalia, specifically recognized the role of the state judiciary in crafting relief: “In the reapportionment context, the Court has required federal judges to defer [to] consideration of disputes involving redistricting where the State, through its legislative or judicial branch, has begun to address that highly political task itself.” Growe, 507 U.S. at 33, 113 S.Ct. 1075 (emphasis original). As an even more pointed endorsement of the state judiciary’s ability to craft appropriate relief— indeed, encouraging action by the state judiciary — the Growe Court quoted its pri- or decision in Scott:

The power of the judiciary of a State to require valid reapportionment or to formulate a valid redistricting plan has not only been recognized by this Court but appropriate action by the States in such cases has been specifically encouraged.

Id. at 33 (quoting Scott, 381 U.S. at 409, 85 S.Ct. 1525) (emphasis added).

Thus, the Growe Court made clear the important role of the state judiciary in ensuring valid reapportionment schemes, not only through an assessment of constitutionality, but also through the enactment of valid legislative redistricting plans. Pursuant to Growe, therefore, although the legislature has initial responsibility to act in redistricting matters, that responsibility can shift to the state judiciary if a state legislature is unable or unwilling to act, and then to the federal judiciary only once the state legislature or state judiciary have not undertaken to remedy a constitutionally infirm plan.

Finally, virtually every other state that has considered the issue looked, when necessary, to the state judiciary to exercise its power to craft an affirmative remedy and formulate a valid reapportionment plan. See, e.g., People ex rel. Salazar v. Davidson, 79 P.3d 1221, 1229 (Colo. 2003) (offering, in addressing the issue of how frequently the legislature can draw congressional districts, that United States Supreme Court is clear that states have the primary responsibility in congressional redistricting, and that federal courts must defer to the states, including state courts, especially in matters turning on state constitution); Hippert v. Ritchie, 813 N.W.2d 374, 378 (Minn. 2012) (explaining that, as legislature and Governor failed to enact a legislative redistricting plan by deadline, it was up to the state judiciary to prepare a valid legislative plan and order its adoption, citing Growe as “precisely the sort of state judicial supervision of redistricting” that the United States Supreme Court has encouraged); Brown v. Butterworth, 831 So.2d 683, 688-89, (D.C. App. Fla 2002) (emphasizing constitutional power of state judiciary to require valid reapportionment); Stephenson v. Bartlett, 355 N.C. 354, 562 S.E.2d 377, 384 (2002) (noting that it is only the Supreme Court of North Carolina that can answer state constitutional questions with finality, and that, “within the context of state redistricting and reapportionment disputes, it is well within the ‘power of the judiciary of a State to, require valid reapportionment or to formulate, a valid redistricting plan’” (quoting Germano, 381 U.S. at 409, 85 S.Ct. 1525)); Wilson v. Fallin, 262 P.3d 741, 745 (Okla. 2011) (holding that three decades after Baker v. Carr, the United States Supreme Court in Growe was clear that state courts may exercise jurisdiction over legislative redistricting and that federal courts should defer to state action over questions of state redistricting by state legislatures and state courts); Alexander v. Taylor, 51 P.3d 1204, 1208. (Okla. 2002) (“It is clear to us that [Baker and Growe], ... stand for the proposition that Art. 1, § 4 does not prevent either federal or state courts from resolving redistricting disputes in a proper case.”); Bone Shirt v. Hazeltine, 700 N.W.2d 746, 755 (S.D. 2005) (Konenkamp, J., concurring) (opining that the Supreme Court recognized that “[t]he power of the judiciary of a State to require valid reapportionment or to formulate a valid redistricting plan has not only been recognized by this Court but appro priate action by the States in such cases has been specifically encouraged!’ and that both “[rjeason and experience argue that courts empowered to invalidate an apportionment statute which transgresses constitutional mandates cannot be left without the means to order appropriate relief.”); Jensen v. Wisconsin Board of Elections, 249 Wis.2d 706, 639 N.W.2d 537, 542 (2002) (per curiam) (noting deference of federal courts regarding “consideration of disputes involving redistricting where the State, through its legislative or judicial branch, has begun to address that highly political task itself’ and that “any redistricting plan judicially ‘enacted’ by a state court (just like one enacted by a state legislature) would be entitled to presumptive full-faith-and-credit legal effect in federal court.”); but see Mauldin v. Branch, 866 So.2d 429 (Miss. 2003) (finding, under Mississippi statute, no Mississippi court had jurisdiction to draw plans for congressional districting).

Thus, it is beyond peradventure that it is the legislature, in the first instance, that is primarily charged with the task of reapportionment. However, the Pennsylvania Constitution, statutory law, our Court’s decisions, federal precedent, and case law from our sister states, all serve as a bedrock foundation on which stands the au-1 thority of the state judiciary to formulate a valid redistricting plan when necessary. Our prior Order, and this Opinion, are entirely consistent with such authority.

VII. Conclusion

For all of these reasons, the Court entered its Order of January 22, 2018, striking as unconstitutional the Congressional Redistricting Act of 2011, and setting forth a process assuring that' a remedial redistricting plan would be in place in time for the 2018 Primary Elections.

CONCURRING AND DISSENTING OPINION

JUSTICE BAER

I respectfully offer this response to the Court’s opinion in support of its order of January 22, 2018 (January 22nd Order). I continue to join the Majority’s conclusion that the Pennsylvania Congressional Redistricting Act of 2011 (2011 Plan) violates the Pennsylvania Constitution, as originally set forth in the first sentence of Paragraph First of the Court’s January 22nd Order. Moreover, I concur with the Majority’s erudite explication of Article I, Section 5 of the Pennsylvania Constitution (the Free and Equal Election Clause), Pa, Const, art. I, § 5, and the Court’s ultimate conclusion that the 2011 Plan violates the rights protected by that provision.

For the reasons explained below and similar to concerns expressed by Chief Justice Saylor and Justice Mundy, I diverge from the Majority, which I read to impose court-designated districting criteria on the Legislature. I, nevertheless, conclude that Pennsylvania’s Free and Equal Election Clause protects Pennsylvanians’ right to vote from dilution resulting from extreme partisan gerrymandering. As elucidated infra, I would hold that extreme partisan gerrymandering occurs when, in the creation of a districting plan, partisan considerations predominate over all other valid districting criteria relevant to the voting community and result in the dilution of a particular group’s vote.

In conformity with the other dissenting-justices, I additionally dissent from the portions of the Majority Opinion supporting the remainder of the January 22nd Order, which enjoin the use of the 2011 Plan for the 2018 election cycle and set forth a procedure for implementing a new map for the May 2018 primary. In my view, as explained below, the Court’s remedy threatens the separation of powers dictated by Article I, Section 4 of the United States Constitution by failing to allow our sister branches sufficient time to legislate a new congressional districting map,. potentially impinges upon the due process rights of the parties at bar as well as other interested parties, and foments unnecessary confusion in the current election cycle.

First, I address my concerns with the “measurement of compliance” discussion set forth in Part V. B, which I interpret as dictating criteria for the Legislature to utilize in redistricting. Article I, Section 4 of the United States Constitution unambiguously provides state legislatures with the authority and responsibility for regulating the election of Senators and Representatives to the United States Congress, subject to any enactment by Congress. Specifically, Article I, Section 4 provides:

The Times, Places and Manner of holding Elections for Senators and Representatives, shall be prescribed in each State by the Legislature thereof; but the Congress may at any time by Law make or alter such Regulations, except as to the Places of [choosing] Senators.

U.S. Const, art. I, § 4. Recently, the United States Supreme Court concluded that the “legislature” designated in Section 4 includes not only the state legislative assembly but also legislative acts of the peo-pie through referenda to amend their state constitutions, such as provisions for independent commissions to draw congressional election districts.

Arizona State Legislature v. Arizona Indep. Redistricting Comm’n, — U.S. -, 135 S.Ct. 2652, 2659, 192 L.Ed.2d 704 (2015). Section 4’s use of the term “legislature,” however, clearly does not encompass the judicial branch, and thus, courts lack the authority to prescribe the “times, places, and manner of holding” congressional elections.

As reiterated by the Majority Opinion, this Court’s January 22nd Order indicated the following:

[T]o comply with this Order, any congressional districting plan shall consist of: congressional districts composed of compact and contiguous territory; as nearly equal in population as practicable; and which do not divide any county, city, incorporated town, borough, township, or ward, except where necessary to ensure equality of population.

January 22nd Order, ¶ “Fourth.” The Majority ably traces the history of the adoption of nearly identical criteria by the framers of the Pennsylvania Constitution for purposes of state senatorial and representative districts. Pa. Const, art. II, § 16. Indeed, the language was also incorporated in regard to municipal election districts. Pa. Const, art. IX, § 11.

In contrast to the state legislative and municipal districts, the Constitution is silent in regard to the criteria to be applied by the Legislature in establishing congressional districts for Representatives to the United States Congress. The designated criteria are also notably absent from the Free and Equal Election Clause, which with elegant simplicity, provides as follows:

Elections shall be free and equal; and no power, civil or military, shall at any time interfere to prevent the free exercise of the right of suffrage.

Pa. Const, art. I, § 5. This language obviously does not address the size or shape of districts. Moreover, there is nothing inherent in a compact or contiguous district that insures a free and equal election, as is evidenced by claims of unconstitutional gerrymandering raised in challenges to redistricting plans of other states which employ maps created in compliance with the traditional districting criteria of compact and contiguous territory, equality of population, and minimization of municipal line division. See, e.g., Whitford v. Gill, 218 F.Supp.3d 837 (W.D. Wis. 2016).

Accordingly, I am unwilling to engraft into the Pennsylvania Constitution criteria for the drawing of congressional districts when the framers chose not to include such provisions despite unquestionably being aware of both the General Assembly’s responsibility for congressional redistricting and the dangers of gerrymandering. It is not this Court’s role to instruct the Legislature as to the “manner of holding elections,” including the relative weight of districting criteria.

I nonetheless agree with the Majority’s holding that the Free and Equal Election Clause protects against the dilution of votes because “a diluted vote is not an equal vote.” Id. at 814. Moreover, I adopt the Majority’s explanation of how extreme partisan gerrymandering “dilutes the votes of those who in prior elections voted for the party not in power to give the party in power a lasting electoral advantage ... [b]y placing voters preferring one party’s candidates in districts where their votes are wasted on candidates likely to lose (cracking), or by placing such voters in districts where their votes are cast for candidates destined to win (packing).” Maj. Op. at 814. Accordingly, I concur with the Majority’s holding that “[a]n election corrupted by extensive, sophisticated gerrymandering and partisan dilution of votes is not “free and equal.” Maj. Op. at 820. Therefore, I conclude that the Free and Equal Clause is violated by .the use of extreme partisan gerrymandering by the Legislature and Governor because it constitutes unconstitutional interference by a civil power “to prevent the free exercise of the right to suffrage” through vote dilution. Pa. Cpnst, art. I, § 5.

■ To evaluate a challenge, to a congressional districting plan, I would hold that a challenger has the burden, to prove that the plan clearly, plainly, .and palpably violates the Free and Equal'Election Clause by demonstrating that the plan resulted from extreme partisan gerrymandering, Stilp v, Commonwealth, 588 Pa. 539, 905 A,2d 918, 939 (2006) (holding that a “legislative enactment will not be deemed unconstitutional unless it clearly, palpably, and plainly violates the Constitution”). I propose that extreme partisan gerrymandering can, in turn, be proven by evidence that partisan considerations predominated over all other valid districting criteria relevant to the voting community and resulted in the dilution of a particular group’s vote.

I further recognize that a fully developed record establishing the absence of traditional districting criteria is indicative of extreme partisan gerrymandering for purposes of vote dilution. As explained by the Majority, because traditional district-ing criteria are “fundamentally impartial in nature, their utilization reduces the likelihood of the creation of congressional districts which confer on any voter ah unequal advantage by giving his or her vote greater weight in the selection of a congressional representative as prohibited by Article I, Section 5.” Maj. Op. at 816. Moreover, I agree that the use of tradi- ■ 'i tional districting criteria “substantially reduces the risk that a voter in a particular congressional-- district will unfairly suffer the dilution of the power of his or her vote.” Id,

■ I do not view, however, the utilization of traditional districting criteria as dispositive in every redistricting case. A map may fail to satisfy all of the traditional criteria and yet pass constitutional muster under the Free and Equal Election Clause, such as where a district is less compact due to a dispersed community of interest. Similarly, traditional districting criteria could be satisfied in a particular case and yet a totality of the evidence could still demonstrate that partisan considerations predominated in the drawing of the map as a result of extreme partisan gerrymandering.

As occurred here, a petitioner may establish that partisan considerations predominated in the drawing of the map by, inter alia, introducing expert analysis and testimony that the adopted map is a statistical outlier in contrast with other maps drawn utilizing traditional districting criteria and that the adopted map was not the product of other legitimate districting considerations such as. the need to protect communities of interest or promote other interests relevant to the voting community. The extensive statistical evidence outlined in detail by Judge Brobsoh in the Commonwealth Court and recounted in the Majority Opinion demonstrates that the 2011 Plan resulted from extreme partisan gerrymandering and, in fact, establishes that this map is one of the most gerrymandered in the nation. On this basis, Petitioners in the case at bar clearly, plainly and palpably demonstrated that partisan considerations predominated over other relevant districting criteria in the drawing of the 2011 Plan and resulted in extreme partisan gerrymandering in violation of Pennsylvania’s Free and Equal Election Clause.

As I join the Court’s conclusion that the 2011 Plan violates the Pennsylvania Constitution’s Free and Equal Election Clause, I turn next to the remedy provided by the Majority in the January 22nd Order, as explained in Part VI of the Majority Opinion. For the reasons set forth in my concurring and dissenting statement to the January 22nd Order, I object to the development of a new redistricting plan for the 2018 election cycle. I continue to suggest respectfully that the Court reconsider its decision given the substantial uncertainty, if not outright chaos, currently unfolding in this Commonwealth regarding the impending elections, in addition to the likely further delays that will result from the continuing litigation before this Court and, potentially, the United States Supreme Court, as well as from the map-drawing process and the litigation that process will inevitably engender.

The Majority correctly observes that'“it is beyond peradventure that it is the legislature, in the first instance, that is primarily charged with the task of reapportionment.” Maj. Op. at 824. Unfortunately, the Legislature does not have a fair opportunity to act “in the first instance” where it has less than three weeks to develop a plan. While it is true that the Legislature technically enacted the 2011 Plan in two weeks, it is naive to think that the legislators created the map in that short period of time, as opposed to developing and negotiating details of . the map over prior months. In fact, the Majority observes that the Legislature began hearings on the dis-tricting map as early as May of 2011 before the December passage of the 2011 Plan, suggesting that the development of the map spanned at least eight .months. • Maj. Op. at 743.

Rather than providing the General Assembly a reasonable opportunity to create a map and pass legislation to adopt it, the Majority has taken steps in preparation for the “possible eventuality” that the Legislature cannot act in this compressed time frame. Order, 1/26/18. Over the objection set forth in Justice Mundy’s dissent, the Majority posits that state courts have the authority under United States Supreme .Court precedent “to devise and impose a reapportionment pjan pending later legislative action” when the legislative bodies fail to act or when “the imminence of a state election makes it impractical for [the legislature] to do so.” Maj, Op. at 823 (internal citations omitted). After reviewing precedent from our sister states and the federal courts, the Majority opines that the precedent serves “as a bedrock foundation on which stands the authority of the state judiciary to formulate a valid redistricting plan when necessary.” Id. at 824.

Respectfully, the circumstances at present do not make it “necessary” for this Court to formulate a redistricting plan for the impending 2018 elections. Instead, the unambiguous grant of redistricting authority to the state legislature under Article I, Section 4 of the Federal Constitution mandates judicial restraint to allow a legislature a reasonable period of time, which should be measured in months rather than weeks, to redistrict following a determination of unconstitutionality by a court, which preferably would provide the legislative bodies with a clear understanding of the nature of the original, plan’s unconstitutionality.

This case does not present a situation where the election cannot go forward under the current map, such as presumably would occur if the plan provided for more representatives than could, be seated in Congress. Indeed, the current map has been utilized for three election cycles, and the Majority is allowing it to be employed again in the upcoming special election for the 18th District. It is, therefore, unnecessary to act prior to the 2018 elections.

In support of its decision to impose a judicially created map in the event that our sister branches fail to enact a plan by February 15th, my colleagues further rely upon this Court’s decision in Butcher v. Bloom, 420 Pa. 305, 216 A.2d 457 (1966). In Butcher, however, the Court in 1964 had provided the Legislature nearly one year to enact a valid map. Butcher v. Bloom, 415 Pa. 438, 203 A.2d 556, 573 (1964). Only after the Legislature failed to pass a constitutional plan during that year did this Court impose a judicially-chosen map. In contrast, this Court has provided the Legislature three weeks from the initial order to produce a new map. In my view, this does not constitute a reasonable time for the Legislature to act.

I also have grave concerns regarding the Court’s procedure for drawing the map should the Legislature and Governor fail to produce one by the dates set forth in the January 22nd Order, and as supple-merited by the January 26th Order, to which I filed a concurring and dissenting statement. The Majority asserts that it has afforded all parties and Intervenors a “full and fair opportunity to submit proposed remedial plans for our consideration.” Maj. Op. at 822.1 do not agree that allowing parties to submit a map comports with due process absent their ability to respond to alternative plans, potentially by submitting additional evidence or cross-examining witnesses. Moreover, the Majority’s remedy lacks any provision for the parties to object following the release of the Court’s map, which may indeed be necessary to advise the Court of any potential oversights or infirmities in the map itself.

Additionally, it is unclear from the Court’s orders whether the Court will “adopt a plan based on the evidentiary record developed in the Commonwealth Court” as set forth in the January 22nd Order, Paragraph Third, or whether the Court will be adopting a map based upon additional evidence submitted by the parties pursuant to the January 26th Order, obtained from the Commonwealth’s public databases, or from sources extrinsic to the record utilized by Professor Persily, which have not been subjected to the rigors of evidentiary challenges either for admissibility or accuracy, as tested through cross-examination. I object to the lack of transparency of this process and urge the Court to provide the parties and the public constitutionally-mandated due process by allowing an opportunity to object to any plan that the Court may adopt.

Finally, as noted in my original concurring and dissenting statement to the January 22nd Order, I have significant concerns that this Court’s unnecessarily compressed timeframe may result in the “[sjerious disruption of orderly state election processes and basic governmental functions.” Butcher, 203 A.2d at 568-69. Indeed, I fear that candidates will be harmed by the shortened time period and that voters will be confused as to their district. The litigation and resulting confusion that has ensued since the release of the January 22nd Order confirm my initial concerns.

DISSENTING OPINION

CHIEF JUSTICE SAYLOR

I incorporate by reference my dissenting statement to the Order of January 22, 2018, per which the majority invalidated Pennsylvania’s current congressional dis-tricting scheme. In summary, I believe that: the present exercise of extraordinary jurisdiction was improvident; this Court’s review would benefit from anticipated guidance from the Supreme Court of the United States; awaiting such guidance is particularly appropriate given the delay, until 2017, of Petitioners’ challenge to a 2011 redistricting plan; and the appropriate litmus for judicial review of redistricting should take into account the inherently political character of the work of the General Assembly, to which the task of redistricting has been assigned by the United States Constitution. See League of Women Voters of Pa. v. Commonwealth, — Pa. -,-, 175 A.3d 282, 284 (2018) (mem.) (Saylor, C.J., dissenting).

Further, I respectfully disagree with the majority opinion in many other material respects. Initially, I certainly have no cause to differ with the broader strokes comprising the bulk of the opinion, including the historical accounts and the confirmation of “a voter’s right to equal protection in the electoral process for the selection of his or her representatives in government,” Majority Opinion, at 804, which is a right that is also recognized under federal constitutional law. See Vieth v. Jubelirer, 541 U.S. 267, 292, 124 S.Ct. 1769, 1785, 158 L.Ed.2d 546 (2004) (plurality) (expressing agreement with a dissenting Justice that severe partisan gerrymanders are inconsistent with democratic principles and may violate the Equal Protection Clause, albeit maintaining that the judiciary is incapable of devising manageable standards for the assessments of degree).

The Supreme Court of the United States has also emphasized, however, that redistricting is committed to the political branch and is inherently political. In this regard, the application of constitutional principles governing individual rights in the context of legislative redistricting is sui generis, given the inevitable- tension between the power allocated to the Legislature to make political choices and the individual rights of voters relative to. the exercise of the franchise. Moreover, in terms of the individual-rights component— and contrary to the majority’s perspective — there is no right to an “equally effective power" of voters in elections, Majority Opinion, at 809. Cf. Vieth, 541 U.S. at 288, 124 S.Ct. at 1782 (“[T]he [federal] Constitution ... guarantees equal protection of the law to persons, not equal representation in government to equivalently sized groups. It nowhere says that farmers or urban dwellers, Christian fundamentalists or Jews, Republicans or Democrats, must be accorded political strength proportionate to their numbers.’’). For example, the phenomenon of “packing,” and the corresponding dilution of the effect of some votes, will occur naturally as a result of population distribution, particularly in urban areas where there is often an aggregation of similar-minded voters. See Vieth, 541 U.S. at 290-91,124 S.Ct. at 1783'; id. at 359, 124 S.Ct. at 1824 (Breyer, J., dissenting).

Given the political character of redistricting, the pervading question relating to partisan considerations, with which courts have had great difficulty, is “how much is too'much?” Id. at 298, 124 S.Ct. at 1788 (quoting id. at 344, 124 S.Ct. at 1815 (Souter, J., dissenting)); accord id. at 313, 124 S.Ct. at 1796 (Kennedy, J., concurring) (commenting on the search for “suitable standards with which to measure the burden a gerrymander imposes on representa-tiohal rights”). Rather than engaging this question in these conventional terms, the majority proceeds to overlay factors delineated by the Pennsylvania Constitution, in. relation to. state-level reapportionment upon congressional redistricting. See Majority Opinion, at 814-17 (prioritizing the factors delineated in Article II, Section 16 of the Pennsylvania Constitution). Since these considerations are not constitutional commands applicable to congressional redistricting, the majority’s approach amounts to a non-textual, judicial imposition of a prophylactic rule.

In this regards it ⅛ significant that the majority’s new rule is oyerprotective, in that it guards not only against intentional discrimination; but also against legislative prioritization of any factor or factors other than those delineated in Article II, Section 16, including legitimate ones. See generally Duckworth v. Eagan, 492 U.S. 195, 209, 109 S.Ct. 2875, 2883, 106 L.Ed.2d 166 (1989) (O’Connor, J., concurring) (explaining that prophylactic rules “overprotect[ ]” the value at stake). Significantly, such additional factors include other traditional districting criteria appropriate to political consideration — such as the preservation of communities of interest, avoidance of pitting incumbents against each other,' and maintenance of the core of prior district lines. See League of Women Voters, — Pa. at —, 175 A.3d at 284 (Saylor, C.J., dissenting) (citing Evenwel v. Abbott, — U.S. —, 136 S.Ct. 1120, 1124, 194 L.Ed.2d 291 (2016), Karcher v. Daggett, 462 U.S. 725, 740, 103 S.Ct. 2653, 2663, 77 L.Ed.2d 133 (1983), and Holt v. 2011 Legislative Reapportionment Comm’n, 620 Pa. 373, 422-23, 67 A.3d 1211, 1241 (2013)).

I do not dispute that prophylactic rules may be legitimate in certain contexts. But they are, by their nature, vulnerable to claims of illegitimacy. See, e.g., Dickerson v. United States, 530 U.S. 428, 465, 120 S.Ct. 2326, 2348, 147 L.Ed.2d 405 (2000) (Scalia, J., dissenting) (depicting a prophylactic rule imposed by the Supreme Court of the United States as an example of “judicial' overreaching”). The consideration of whether this sort of rule should be imposed by the judiciary upon a process committed by the federal Constitution to another branch of government seems to me to require particular caution and restraint. Accord Vieth, 641 U.S. at 301, 124 S.Ct. at 1789 (discussing the drawbacks of “insertion of the judiciary into districting,” including “the delay and uncertainty [it] brings to the political process and the partisan enmity it brings upon the courts”); id. at 291; 124 S.Ct. at 1784 (alluding to the interests in “meaningfully constrain[ing] the discretion of the courts, and to win public acceptance for the courts’ intrusion into a process that is the very foundation of democratic decisionmaking”).

Quite clearly, the character of redistricting, and concomitant separation-of-powers concerns, warrant special caution on the part of the judiciary in considering regulation and intervention. See generally Colo. Gen. Assembly v. Salazar, 541 U.S. 1093, 1095, 124 S.Ct. 2228, 2229,159 L.Ed.2d 260 (2004) (Rehnquist, C.J., dissenting from denial of certiorari) (observing, in the context of a state supreme court’s broad insertion of the judiciary into the, redistricting process, that the constitutional “words, ‘shall be prescribed in each State by the Legislature thereof operate as a limitation on the State” (emphasis in original)), Indeed, as Justice Kennedy of the Supreme Court of the United States has opined: “A decision ordering the correction of all election district lines drawn for partisan reasons would commit federal and state courts to. unprecedented intervention in the American political process[,]” yielding “substantial intrusion into the Nation’s political life.” Vieth, 541 U,S. at 306, 124 S.Ct. at 1792-93 (Kennedy, J., concurring).

From my point of view, the majority opinion fails to sufficiently account for the fundamental character of redistricting, its allocation under the United States Constitution to the political branch, and the many drawbacks of constitutionalizing a non-textual judicial rule. For my own part, I would abide by the Court’s previous determination, in the redistricting setting, that the Free and Equal Elections Clause provides no greater protection than the state charter’s Equal Protection Clauses, which have been deemed coterminous with the protection provided by the United States Constitution. See Erfer v. Commonwealth, 568 Pa. 128, 138-39, 794 A.2d 325, 332 (2002). I find that the majority’s focus on a limited range of traditional districting factors allocates too much discretion to the judiciary, to discern violations in the absence of proof of intentional discrimination. Instead, I believe that, under the state and federal charters, the discretion belongs to the Legislature, which should be 'accorded appropriate deference and comity, as reflected in the majority’s initial articulation of the presumption of constitutionality and the heavy burden borne by challengers. See Majority Opinion, at 801.

As I said in my previous dissenting statement, I appreciate that the recommended factual findings of Judge Brobson of the Commonwealth Court suggest that the Court may be faced with a scenario involving extreme partisan gerrymandering. Were the present process an ordinary deliberative one, I would proceed to sift through the array of potential standards to determine if there was one which I could conclude would be judicially manageable. See generally Vieth, 541 U.S. at 292, 124 S.Ct. at 1784 (observing that, among the expressions of the four dissenting Justices in Vieth, three different standards had emerged). In my judgment, however, the acceptance of Petitioners’ entreaty to proceed with extreme exigency presents too great of an impingement on the deliberative process to allow for a considered judgment on my part in this complex and politically-charged area of the law.

Finally, as to the remedy, I disapprove of the imposition of a judicially-drawn map for the above reasons. Furthermore, as Justice Baer discusses at length, the per curiam Order inviting the Legislature to redraw Pennsylvania’s congressional districts provided very little time and guidance in the enterprise. See Concurring and Dissenting Opinion, at 826, 828-31 (Baer, J.). Although I do not dispute that judicial intervention may possibly be appropriate — where a constitutional violation is established based on the application of clear standards pertaining to intentional discrimination and dilution of voting power, and the Legislature has been adequately apprised of what is being required of it and afforded sufficient time to comply— regrettably, I submit that this is simply not what has happened here.

Justice Mundy joins this dissenting opinion.

DISSENTING OPINION

JUSTICE MUNDY

I respectfully dissent. Today the Majority announces that the Pennsylvania Congressional Redistricting Act of 2011 clearly, plainly and palpably violates the Pennsylvania Constitution on the basis of the Free and Equal Elections Clause. See generally Pa. Const, art. I, § 5. The claim here is not that voters were unable to cast their vote, but rather that the power of the individual voters was diluted, thus preventing them from electing candidates of their choice. The Majority concedes, “[n]either Article 1, Section 5, nor any other provision of our Constitution, articulates explicit standards which are to be used in the creation of congressional districts.” Majority Op. at 814. Nevertheless, the Majority holds that “certain neutral criteria” are to be utilized in drawing congressional districts in this Commonwealth. Id.

In Erfer v. Commonwealth, 568 Pa. 128, 794 A.2d 325 (2002), a partisan gerrymandering case, this Court rejected the “[petitioners’ claim that the Pennsylvania Constitution’s free and equal elections clause provides further protection to the right to vote than does the Equal Protection Clause.” Id. at 332. The Court further noted that the petitioners had failed to persuade us “why we should, at this juncture, interpret our constitution in such a fashion -that the right to vote is more expansive than the guarantee found in the federal constitution.” Id. Despite the fact that Erfer established the Free and Equal Elections Clause did not provide any heightened protections to Pennsylvania voters, the Majority fails to provide legal justification for its disapproval of Erfer, other than citing to Shankey v. Staisey, 436 Pa. 65, 257 A.2d 897 (1969), which predates Erfer by 33 years. In my view, stare decisis principles require us to give Erfer full effect.

Recognizing that the Pennsylvania Constitution does not articulate explicit standards to be used in the creation of congressional districts, the Majority fashions a three part test: “(1) the population of such districts must be equal, to the extent possible; (2) the district that is created must be comprised of compact and contiguous geographical territory, and (3) the district respects the boundaries of existing political subdivisions contained therein, such that the district divides as few of those subdivisions as possible.” Majority Op. at 815. These vague judicially-created “neutral criteria” are now the guideposts against which all future congressional redistricting maps will be evaluated, with this Court as the final arbiter of what constitutes too partisan an influence. Id. at 816.

In this regard, the Majority acknowledges that these “neutral criteria”, only establish a constitutional floor. Majority Op. at 816. However, the Majority admits that it is possible for the General Assembly to draw a map that fully complies with the Majority’s “neutral criteria” but still “operate[s] to -unfairly dilute the power of a particular group’s vote for á congressional representative.” Id. at 817. This undermines the conclusion that there is a clear, plain, and palpable constitutional violation in this case.

As I. explained in my January 22, 2018 Dissenting, Statement, I also have grave concerns about the Majority’s remedy. I agree with the Majority that we have the authority to direct the legislative and executive branches of our government to draw new maps to remedy any violation of law. However, I am troubled by the Majority’s decision to strike down the 2011 congressional map on the eve of the 2018 midterm election. Particularly its disregard for precedent which supports, deferring redistricting until after the 2018 election. See generally Butcher v. Bloom, 415 Pa. 438, 203 A.2d 556, 568 (1964). I further share the concerns expressed by the dissenting opinion of Chief Justice Saylor and • the dissenting portion of the concurring and dissenting opinion of Justice Baer that this is a political process the General Assembly should be afforded the full opportunity and adequate time to address. I write further only to address the remedy suggested by the Majority of bestowing the task of drawing a new Congressional map onto itself, in the face of a clear legislative alternative,

The Majority states it fully supports the “preferred path of legislative and executive action,” and concedes “that the primary responsibility and authority for drawing federal congressional legislative districts rests squarely with the state legislature.” Majority Op. at 821. Notwithstanding this, the Majority declares its remedy “was well within our judicial authority, and supported by not only our Constitution and statutes .,. but by Commonwealth and federal precedent, as well as similar remedies provided by the high courts of ..other states, acting when their sister branches fail to remedy an unconstitutional plan.” Id. at .822.

The Majority cites Butcher as support for its remedy, but omits that the Court in Butcher granted the General Assembly 11 months to draft a new map before intervening, yet it nevertheless concludes its remedy is - “entirely consistent with ... Butcher.” Id. This Court has always had the pragmatic option to utilize the current congressional maps for the 2018 election, while allowing the General Assembly the appropriate amount of time to redraw our legislative districts. Further, as I discuss below, the magnitude and breadth of the Majority’s remedy is inconsistent with the restraints imposed by federal law.

The Elections Clause of the Federal Constitution states that “[t]he Times, Places and Manner of holding' Elections for Senators and Representatives, shall be prescribed in each State by the Legislature thereof; but the Congress may at any time by Law make or alter such Regulations, except as to the Places of chusing Senators.” U.S. Const, art I, § 4, cl. 1 (emphasis added). The Elections Clause at its core, grants the authority to draw á state’s congressional districts to the state legislatures', ‘Congress, or an independent redistrictirig commission. Ariz. State Leg- Mature v. Ariz. Indep. Redist. Comm’n, — U.S. —, 135 S.Ct. 2652, 2667-68, 192 L.Ed.2d 704 (2015). As the Supreme Court of the United States recognized, “redistricting is a legislative function, to be performed in accordance with the State’s prescriptions for lawmaking, which may include the referendum and the Governor’s veto.” Id. at 2668. It is a truism that this Court possesses neither legislative function, nor authority. While this Court is certainly the final arbiter of the meaning of the Pennsylvania Constitution, it may not remedy any violations of our state charter, in a manner, that the Federal Constitution prohibits. After all, federal law ,is supreme. U.S. Const, art. VI, cl. 2.

The Majority points to certain cases that in its view “make concrete the state’judiciary’s ability to formulate a redistricting plan, when necessary.” Majority Op. at 823. At the outset, on this point, we can set aside Butcher v. Bloom, 420 Pa. 305, 216 A.2d 457 (1966), which pertains to the state legislative districts of the General Assembly. Butcher, 216 A.2d at 457-58. The Elections Clause does not itself circumscribe this Court’s authority in drawing a state legislative map, as the Elections Clause only refers to “[t]he Times, Places and Manner of holding Elections for Senators .and Representatives[.]” U.S. Const, art I, § 4, cl. 1; see also Clingman v. Beaver, 544 U.S. 581, 586, 125 S.Ct. 2029, 161 L.Ed.2d 920 (2005) (stating, that the power granted to the States under the Elections Clause “is matched by state control over the election process for state offices.”).

Turning to the cases of the Supreme Court of the United States cited by the Majority, none of them support the remedy contemplated here. In Scott v. Germano, 381 U.S. 407, 85 S.Ct. 1525, 14 L.Ed.2d 477 (1965), the Supreme Court issued an unsigned per curiam opinion pertaining to apportionment among the Illinois Senate and the Illinois House of Representatives, which is outside the purview of the Elections Clause. Scott, 381 U.S. at 408, 85 5.Ct. 1525.

Nor did the Court contemplate the Elections Clause in Growe v. Emison, 507 U.S. 25, 113. S.Ct. 1075, 122 L.Ed.2d 388 (1993). In Growe, the Court, in an opinion authored by- Justice Scalia, only considered the question of Pullman abstention. Briefly, there was dueling federal and state litigation about Minnesota’s state and federal legislative districts. Growe, 507 U.S. at 27-28, 113 S.Ct. 1075. The Court held the federal district court should have deferred any judicial intervention until the Minnesota courts had fully resolved its case. The Elections Clause was not an issue in Growe, the Court merely observed what the Minnesota judiciary had done, and it did not hold it to be constitutionally valid. The Court’s opinion in Growe sheds no light on whether a state court’may take on the task of drawing a federal congressional map in the first instance.

The Court points out that in Wise v. Lipscomb, 437 U.S. 535, 98 S.Ct. 2493, 57 L.Ed.2d 411 (1978), the Supreme Court stated, “[¡legislative bodies should not leave their reapportionment tasks to the federal courts; but when those with legislative responsibilities do not respond, or the imminence of a state election makes it impractical for them to do so, it becomes the ‘unwelcome obligation,’ ... of the federal court to devise and impose a reapportionment plan pending later legislative action.” Wise, 437 U.S. at 540, 98 S.Ct. 2493; see also Majority Op. at 823. The Majority’s reliance on this sentence is misplaced for two reasons. First, like the other cases, Wise pertained to a Texas local districting scheme for the Dallas City Council, which is outside the Elections Clause’s sphere of concern. Id. at 537-38, 98 S.Ct. 2493; see also U.S. Const, art I, § 4, cl. 1.

More importantly, Wise arose out of a federal court action. As noted above, by its very text, the Elections Clause leaves the task of apportionment to state legislatures. However, the Clause also explicitly contemplates that Congress may override state legislatures as it wishes in this area. See Ariz. State Legislature, 135 S.Ct. at 2670 (stating, “[tjhere can be no dispute that Congress itself may draw a State’s congressional-district boundaries.”); accord Vieth v. Jubelirer, 541 U.S. 267, 275, 124 S.Ct. 1769, 158 L.Ed.2d 546 (2004) (plurality). Of course, that same Congress is empowered to shape the jurisdiction of the federal judiciary, with certain exceptions not relevant here. See generally U.S. Const. art. Ill, § 1. It is therefore unsurprising that Congress may empower the federal judiciary to entertain civil suits and grant relief in a manner that overrides the maps drawn by state legislatures, where Congress may do the same directly through legislation. Indeed, the Court has expressly observed the Voting Rights Act of 1965 contemplates such relief. See Branch v. Smith, 538 U.S. 254, 268, 123 S.Ct. 1429, 155 L.Ed.2d 407 (2003).

For the foregoing reasons, I respectfully dissent.

      . On November 17, 2017, the Commonwealth Court dismissed the League of Women Voters from the case based on a lack of standing. On the presentations before us, see Petitioners’ Brief at 41 n.5, and given our resolution of this matter, we do not revisit that decision.-
     
      
      . A similar challenge, under federal law, was brought by citizen-petitioners against the Governor, the Secretary, and the Commissioner in federal district court, contending that Plan violates the Elections Clause, Article I, Section 4, of the federal Constitution. Trial in that case was held in December, one week prior to the trial in the instant matter. In a 2-1 decision, on January 10, 2018, the three-judge panel of the United States District Court for the Eastern District of Pennsylvania rejected the petitioners' challenge. See Agre v. Wolf, 284 F.Supp,3d 591, 2Ó18 WL 351603 (E.D. Pa. 2018).
     
      
      .On November 13, 2017, the Commonwealth Court permitted to intervene certain- regis- ■ téred Republican voters' from each district, including announced or potential candidates for Congress and other active members of the Republican Party (the “Intervenors”).
     
      
      . To our Order, Justice Baer filed a Concurring and Dissenting Statement, Chief Justice Saylor filed a Dissenting Statement, joined by Justice Mundy, and Justice Mundy filed a Dissenting Statement.
     
      
      . In our order, we excepted .the March 13,. 2018 special election for Pennsylvania's 18th Congressional District. See Ordér, 1/22/18, . ¶ “Sixth.”
     
      
      . On January 23, 2018, Legislative Respondents filed with this Court an application for a stay of our Order, alleging the Order would have a chaotic effect on the 2018 elections, and arguing the Order implicated an important question of federal law on which they would base an appeal to the United States Supreme Court. Intervenors filed a similar application. Both applications were denied on January 25, 2018, with dissents noted by Chief Justice Saylor, and Justices Baer and Mundy. On January 26, 2018, Legislative Respondents filed with the United States Supreme Court an emergency application for a stay of this Court's January 22, 2018 Order; the application was denied on February 5, 2018.
     
      
      . A brief description of the Court’s process in issuing orders with opinions to follow is instructive. Upon agreement of the majority of the Court, the Court may enter, shortly after briefing and argument, a per curiam order setting forth the court’s mandate, so that the parties are aware of the court’s ultimate decision and may act accordingly. This is particularly so in election matters, where time is of the essence. Justices in the minority, or who disagree with any part of the order, may issue brief concurring or dissenting statements, or may simply note their concurrence with or dissent from the order.
      The Court is, however, still a deliberative body, meaning there is a back-and-forth nature not only to decision-making, but to legal analysis. Many analyses, such as those in this case, are complex and nuanced. Thus, the Court's process involves, in the first instance, the drafting of an opinion by the majority author, and, of course, involves exhaustive research and multiple interactions with other Justices. Once a majority opinion is completed, it is circulated to all of the other Justices for their review and comment. At that point, each of the other Justices has the opportunity to write his or her own concurring or dissenting opinions, expressing that Justice’s ultimate views on the issues presented. These responsive opinions are then circulated to the other Justices for their responses, if any. Only then, after every member of the Court has been afforded the time and opportunity to express his or her views, are the opinions finalized. At that point, a majority opinion, along with any concurring and dissenting opinions, are filed with our Prothonotary and released to the public. It is a process, and it is one to which this Court rigorously adheres.
     
      
      . Public Law 94-171, enacted by Congress in 1975, requires the Census Bureau to deliver redistricting results to state officials for legislative redistricting. See 13 U.S.C. § 141. For the 2010 federal census, the Census Bureau was required to deliver redistricting data to the states no later than April 1, 2011,
     
      
      . By contrast, the state legislative lines are drawn by a five-member commission pursuant to the Pennsylvania Constitution, See Pa. Const, art. II, § 17.
     
      
      . Both the Elections Clause and Section 2a have been interpreted as envisioning that the redistricting process will be subject to state law restrictions, including gubernatorial veto, judicial remedies, citizen referenda, and even the reconstitution, via citizen initiative, of the authority to redistrict into independent redistricting agencies. The role of courts generally, and this Court in particular, in fashioning congressional districts is a matter we discuss more fully below in Part VI, "Remedy.”
     
      
      . This history is based on the joint stipulation of the parties. See Joint Stipulation of Facts, 12/8/17.
     
      
      ., Notably, 33 of the 36 Democrats who voted in favor of passage serve districts within the 1st, 2nd, 13th, 14th, or 17th Congressional Districts, which, as detailed herein, are safe Democratic districts under the 2011 Plan.
     
      
      . As with the legislative history of the 2011 Plan, this description is based upon the joint stipulation of the parties.
     
      
      . The 2011 Plan also consolidates previously split counties: prior to the 2011 Plan, Armstrong, Butler, Mercer, Venango, and Warren Counties were split between congressional districts, whereas, under the 2011 Plan, they are not.
     
      
      .- The City of Reading is separated from the remainder of Berks County. From at least 1962 to 2002, Berks County was situated entirely within a single congressional district.
     
      
      . The City of Coatesville is separated from the remainder of Chester County.
     
      
      . From at least 1931 until 2011, Erie County was not split between congressional districts.
     
      
      . The City of Easton is separated from the remainder of Northampton County.
     
      
      . In total, 11 of the 18 congressional districts contain more than three counties which are divided among multiple congressional districts.
     
      
      .The municipalities include Archbald, Barr, Bethlehem, Cain, Carbondale, Chester, Cuna-ra, Darby, East Bradford, East Carroll, East Norriton, Fallowfield, Glenolden, Harrisburg, Harrison, Hatfield, Hereford, Horsham, Ken-nett, Laureldale, Lebanon, Lower Alsace, Lower Gwynedd, Lower Merion, Mechanics-burg, Millcreek, Monroeville, Morgan, Muh-lenberg, North Lebanon, Northern Cambria, Olyphant, Penn, Pennsbury, Perkiomen, Philadelphia, Piney, Plainfield, Plymouth Township, Ridley, Riverside, Robinson, Sadsbury, Seven Springs, Shippen, Shippensburg, Shirley, Spring, Springfield, Stroud, Susquehanna, Throop, Tinicum, Trafford, Upper Allen, Upper Darby, Upper Dublin, Upper Gwynedd, Upper Hanover, Upper Merion, Upper Nazareth, West Bradford, West Hanover, West Norriton, Whitehall, Whitemarsh, Whitpain, and Wyomissing. Monroeville, Cain, Cumra, and Spring Township are split into three separate congressional districts. Three of these municipalities — Seven Springs, Shippens-burg, and Trafford — are naturally divided between multiple counties, and Cumra is naturally noncontiguous. Additionally, wards in Bethlehem and Harrisburg are split between congressional districts.

      . One elective representative, Thomas M. Foglietta, was not elected as either a Democrat or Republican in 1980.
     
      
      . Specifically, in 2012, Democratic candidates won in the 1st Congressional District with 84.9% of the vote; the 2nd Congressional District with 90.5% of the vote; the 13th Congressional District with 69.1% of the vote; the 14th Congressional District with 76.9% of the vote; and the 17th Congressional District with 60.3% of the vote. On the other hand, Republican candidates won in the 3rd Congressional District with 57.2% of the vote; the 4th Congressional District with 63.4% of the vote; the 5th Congressional District with 62.9% of the vote; the 6th Congressional District with 57.1% of the vote; the 7th Congressional District with 59.4% of the vote; the 8th Congressional District with 56.6% of the vote; the 9th Congressional District with 61.7% of the vote; the 10th Congressional District with 65.6% of the vote; the 11th Congressional District with 58.5% of the vote; the 12th Congressional District with 51.7% of the vote; the 15th Congressional District with 56.8% of the vote; the 16th Congressional District with 58.4% of the vote; and the 18th Congressional District with 64.0% of the vote.
     
      
      . Specifically, in 2014, Democrats won in the 1st Congressional District with 82.8% of the vote; the 2nd Congressional district with 87.7% of the vote; the 13th Congressional District with 67.1% of the vote; the 14th Congressional District, which was uncontested, with 100% of the vote; and the 17th Congressional District with 56.8% of the vote. Republican candidates won in the 3rd Congressional District with 60.6% of the vote; the 4th Congressional District with 74.5% of the vote; the 5th Congressional District with 63.6% of the vote; the 6th Congressional district with 56.3% of the vote; the 7th Congressional District with 62.0% of the vote; the 8th Congressional District with 61.9% of the vote; the 9th Congressional District with 63.5% of the vote; the 10th Congressional District with 71.6% of the vote; the 11th Congressional District with 66.3% of the vote; the 12th Congressional District with 59.3% of the vote; the 15th Congressional District, which was uncoritested, with 100% of the vote; the 16th Congressional District with 57.7% of the vote; and the 18th Congressional District, which was uncontested, with 100% of the vote.
     
      
      .Specifically, in 2016, Democrats again prevailed in the 1st Congressional District with 82.2% of the vote; the 2nd Congressional District with 90.2% of the vote; the 13th Congressional District, which was uncontested, with 100% of the vote; the 14th Congressional District with 74.4% of the vote; and the 17th Congressional District with 53.8% of the vote. Republicans again prevailed in the remainder of the districts; in the 3rd Congressional district, which was uncontested, with 100% of the vote; in the 4th Congressional District with 66.1% of the vote; in the 5th Congressional District with 67.2% of the vote; in the 6th Congressional District with 67.2% of the vote; in the 7th Congressional District with 59.5% of the vote; in the 8th Congressional District with 54.4% of the vote; in the 9th Congressional District with 63,3% of the vote; in the 10th Congressional District with 70.2% of the vote; in the 11th Congressional District with 63.7% of the vote; in the 12th Congressional District with 61.8% of the vote; in the 15th Congressional District with 60.6% of the vote; in the 16th Congressional District with 55.6% of the vote; and in the 18th Congressional District, which was uncontested, with 100% of the vote.
     
      
      .Notably, voters in the 6th and 7th Congressional Districts reelected Republican congressmen while simultaneously voting for Democratic nominee and former Secretary of State Hillary Clinton for president. Contrariwise, voters in the 17th Congressional District reelected a Democratic congressman while voting for Republican nominee Donald Trump for president. Additionally, several traditionally Democratic counties voted for now-President Trump.
     
      
      . Petitioners challenged, and before us continue to challenge, the Plan as a whole. Whether such challenges are properly brought statewide, or must be district specif- ' ic, is an open question. See Vieth v. Jubelirer, 541 U.S. 267, 124 S.Ct. 1769, 158 L.Ed.2d 546 (2004). However, no such objection is presented to us,

      . The court’s December 29, 2017 Recommended Findings of Fact and Conclusions of Law is broken into two principal, self-explanatory parts. Herein, we refer to those two parts as "Findings of Fact” and "Conclusions of Law.”
     
      
      . The Speech and Debate Clause provides: The members of the General Assembly shall in all cases, except treason, felony, violátion of their oath of office, and breach or surety of the peace, be privileged from arrest during their attendance at the sessions of their respective Houses and in going to and returning from the same; and for any speech or debate in either House they shall not be questioned in any other place. Pa. Const, art. II, § 15.
     
      
      . Petitioners sought discovery from various third parties, including, inter alia, the Republican National Committee, the National Republican Congressional Committee, the Republican State Leadership Committee, the State Government Leadership Foundation, and former Governor Corbett, requesting all documents pertaining to the 2011 Plan, all documents pertaining the Redistricting Majority Project (REDMAP), all communications and reports to donors that refer to or discuss the strategy behind REDMAP or evaluate its success, and any training materials on redistricting presented to members, agents, employees, consultants or representatives of the Pennsylvania General Assembly and former Governor Corbett. The discoveiy request was made for the purpose of establishing the intent of Legislative Respondents to dilute the vote of citizens who historically cast their vote for Democratic candidates. Legislative Respondents opppsed the request, asserting, in relevant part, that the information sought was privileged under the Speech and Debate Clause of Article I, Section 15 of the Pennsylvania Constitution. Agreeing with Legislative Respondents, the Commonwealth Court denied the discovery request, excluding any documents that reflected communications with members of the General Assembly or “the intentions, motivations, and activities of- state legislators and their staff with respect to the consideration and passage of- [the 2011 Plan],” see Commonwealth Court Opinion, 11/22/17, at 11-13, and later denied the admission of such information produced in the federal court action.,
      Given the other unrebutted evidence of the intent to dilute the vote of citizens who historically voted for Democratic candidates, we need not resolve the question of whether our Speech and Debate Clause confers a privilege protecting this information from discovery and use at trial in a case, such as this one, involving a challenge to the constitutionality of a statute. However, we caution against reliance on the Commonwealth Court’s ruling. This Court has never interpreted our Speech and Debate. Clause as providing, anything more' than immunity from suit, in certain circumstances, for individual members of the General Assembly. See, e.g., Sweeney v. Tucker, 473 Pa. 493, 375 A.2d 698 (1977). Although not bound by decisions interpreting the federal Speech or Debate Clause in Article I, Section 6 of the United States Constitution, see id. at 703 n.14, we note that the high Court has recognized an evidentiary privilege only in cases where an individual legislator is facing criminal charges. See, e.g., United States v. Johnson, 383 U.S. 169, 86 S.Ct. 749, 15 L.Ed.2d 681 (1966); United States v. Helstoski, 442 U.S. 477, 99 S.Ct. 2432, 61 L.Ed.2d 12 (1979). To date, the United States Supreme Court has never held that an eviden-tiary privilege exists under the Speech or Debate Clause in lawsuits challenging the constitutionality of a statute. Further, we are not aware of any precedent to support the application of any such privilege to information in the possession of third parties, not legislators.

Generally, the testimony of the aforementioned Petitioners demonstrates a belief that the 2011 Plan has negatively affected their ability to influence the political process and/or elect a candidate who represents their interests. See Findings of Fact at ¶¶ 221-34, Petitioners also introduced excerpts from the trial testimony of State Senator Andrew E. Dinniman in Agre v. Wolf, Petitioners’ Exhibit 178, and excerpts from the deposition testimony of State Representative Gregory Vitali, Petitioners’ Exhibit 179. Senator Dinniman and Representative Vitali both testified as to the circumstances surrounding the enactment of the 2011 Plan.

      . Following the presentation of Dr. War-shaw’s testimony, Petitioners requested permission to admit into the record'Several documents, including: Petitioners’ Exhibit 124 (Declaration of Stacie Goede, Republican State Leadership Conference); Petitioners’ Exhibit 126 (Redistricting 2010 Preparing for Success); Petitioners’ Exhibit 127 (RSLC Announces Redistricting Majority Project (REDMAP); Petitioners’ Exhibit 128 (REDistricting Majority Project); Petitioners’ Exhibit 129 (REDMAP Political Report: July 2010); Petitioners’ Exhibit 131 (REDMAP 2012 Summaiy Report); Petitioners’ Exhibit 132 (REDMAP Political Report: Final Report); Petitioners' Exhibit 133 (2012 RSLC Year in Review); Petitioners' Exhibit 134 (REDMAP fundraising letter); and Petitioners' Exhibit 140. (“Map-CD18 Maximized”). As noted above, the Commonwealth Court sustained Respondents’ objections to the admission of these documents, but admitted them under seal "for the sole purpose of ... allowing the Supreme Court to revisit my evidentiary ruling if it so chooses.” N.T. Trial, 12/13/17, at 1061; see id. at 1070. Petitioners also moved for the admission of Exhibits 27, 28, 29, 30, 31, and 33. The court refused to admit Exhibits 27, 28, 29, 30, and 31, and reiterated that it had previously ruled on Exhibit 33 and held it was not admissible. Id. at 1077. The court also refused to admit Exhibits 135, 136, 137, 138, 139, and 141-161. Id. at 1083.
     
      
      . The court contrasted the General Assem--bly’s freedom in this regard with the Legislative Reapportionment Commission's relatively lesser freedom in performing state legislative redistricting, which, as noted above, is governed by Article II, Section 16 of the Pennsylvania Constitution; political subdivisions’ lesser freedom in performing political-subdivision redistricting, which is governed by Article IX, Section 11 of the Pennsylvania Constitution; and other states’ lesser freedom in performing congressional redistricting subject to their own state restrictions, see Conclusions of Law at ¶ 7 (citing, as an example, Va. Const, art. II, § 6 (requiring Virginia's Congressional districts to be contiguous and compact)).
     
      
      . Actually, such a claim’s justiciability under federal law is, at best, unclear. In Bandemer, the United States Supreme Court held that such claims are justiciable under the Equal Protection Clause, but was unable to agree on an adjudicative-standard. However,, in Vieth, the- court revisited the issue, and a four-Justice plurality indicated they would overrule Bandemer's holding, with an equal- number of Justices indicating they would reaffirm it, although they remained unable to agree on an adjudicative standard. See Vieth, 541 U.S. at 270-306, 124 S.Ct. 1769 (plurality opinion) (Scalia, J., joined by Rehnquist, C.J., O’Con-nor, J., and Thomas, J.); id. at 317, 124 S.Ct. 1769 (Stevens, J. dissenting); id. at 342-55, 124 S.Ct. 1769 (Souter, X, joined by Ginsburg, X, dissenting); id. at 355-68, 124 S.Ct. 1769 (Breyer, J„ dissenting). Justice Kennedy, concurring in the judgment, agreed with the plurality that the claim at bar was nonjusticia-ble, insofar as he viewed some political partisan or political classifications as permissible and, largely due to that circumstance, could not glean an appropriate adjudicative standard, but declined to foreclose future claims for which he expressed optimism that such a standard might be determined. See id. at 308-17, 124 S.Ct. 1769 (Kennedy, X, concurring in the judgment).
     
      
      . Later, the Commonwealth Court explained:
      [s]ome unanswered questions that arise based on Petitioners' presentation include: (1) what is a constitutionally permissible efficiency gap; (2) how many districts must be competitive in order for a plan to pass constitutional muster (realizing that a corn-petitive district would result in a skewed efficiency gap); (3) how is a "competitive” district defined; (4) how is a "fair” district defined; and (5) must a plan guarantee a minimum number of congressional seats in favor of one party or another to be constitutional

      . The court further opined that Erfer was “consistent with decades of Pennsylvania Supreme Court precedent holding that the ‘equal protection provisions of the Pennsylvania Constitution are analyzed .,. under the same standards used by the United States Supreme Court when reviewing equal protection claims under the Fourteenth Amendment to the United States Constitution.’ ” Conclusions of Law at ¶ 45 (quoting Love, 597 A.2d at 1139; citing Commonwealth v. Albert, 563 Pa. 133, 758 A.2d 1149, 1151 (2000); James v.

      . Notably, in Erfer, our determination that the Equal Protection Guarantee was to be adjudicated as coterminous with the Equal Protection Clause of the Fourteenth Amendment to the United States Constitution was predicated on Love, in which we merely remarked that the Equal Protection Guarantee and Equal Protection Clause involve the same jurisprudential framework — i.e., a means-ends test taking into account a law’s use of suspect classification, burdening of fundamental rights, and its justification in light of its objectives, See Erfer, 794 A.2d at 331-32; Love, 597 A.2d at 1139. The same was true in Kramer, where we remarked that we had previously employed “the same standards applicable to federal equal protection claims” and that the parties therein did not dispute “that the protections [were] ’coterminous[.]” Kramer, 883 A.2d at 532. ■ Moreover, our affirmance in Zauflik was rooted in the parties’ failure to conduct an analysis under Commonwealth v. Edmunds, 526 Pa, 374, 586 A.2d 887 (1991). See Zauflik, 104 A.3d at 1117 n.10; infra note 53. Finally, concerning Doe, the issue was not meaningfully litigated before the Commonwealth Court, and, in any event, this Court affirmed its decision per curiam, rendering it of no salient precedential value in the instant case. See Commonwealth v. Tilghman, 543 Pa. 578, 673 A.2d 898, 903-03 (1996) (noting that orders affirming a lower courts decisión, as opposed to its opinion, per curiam should not be construed as endorsing its reasoning).
     
      
      . Notably, as discussed below, although we did reject in Erfer the suggestion that the Free and Equal Elections Clause provided greater protection of the right to vote than the Equal Protection Guarantee, our rejection was predicated on the lack of a persuasive argument to ' that end. Erfer, 794 A.2d at 331-32,
     
      
      . On the court's last point, one imagines that Petitioners find cold comfort in their right to protest and advocate for change in an electoral system that they allege has been structurally designed to marginalize their efforts in perpetuity.
     
      
      .' Edmunds instructs that an analysis of whether a right under the Pennsylvania Constitution affords greater protection than the United States Constitution encompasses the following four factors:
      1) text of the Pennsylvania constitutional •provision;
      2) history of the provision, including Pennsylvania case-law;
      3)related case-law from other states;
      '4) policy considerations, including unique issues of state and local concern, and applicability within modern Pennsylvania jurisprudence,

      . As noted above, in our landmark decision in Edmunds, our Court set forth a four-part test which we routinely follow in examining and interpreting a provision of our Commonwealth's organic charter. This test examines (1) the relevant text of the provision of Pennsylvania Constitution; (2) the history of the provision, including Pennsylvania case law; (3) relevant case law from other jurisdictions interpreting similar provisions of that jurisdiction's constitution; and (4) policy considerations.

      . The 1790 Constitution was never ratified by popular vote; however, all subsequent constitutions in which this language is included have been ratified by the people of the Commonwealth,
     
      
      . Indeed, the majority of delegates expressly rejected a proposal to remove the “and equal” language from the revised am'endment. Minutes of the Constitutional Convention of 1789 at 377. Ours, thus, became the first constitution to utilize this language, and other states such as Delaware, following our lead, adopted the same language into their constitution a mere two years later in 1792. Eleven other states since then have included a "free and equal” clause in their constitutions.
     
      
      . See supra note 8.
     
      
      . Like Pennsylvania, a number of other states go further than merely recognizing the right to vote, and provide additional and independent protections through provisions in their constitutions guaranteeing that their elections shall be "free and equal." Pa, Const, art. I, § 5. More specifically, the constitutions of twelve additional states contain election clauses identical to our charter, requiring elections to be “free and equal.” These twelve other states are: Arizona, Ariz, Const, art. II, § 21; Arkansas, Ark. Const, art. 3, § 2; Delaware, Del. Const, art.- I, § 3; Illinois, Ill, Const, art. Ill, § 3; Indiana, Ind. Const, art. 2, § 1; Kentucky, Ky. Const. § 6; Oklahoma, Okla. Const, art. Ill, § 5; Oregon, Or. Const, art. II, § 1; South Dakota, S.D. Const art. VI, § 19; Tennessee, Tenn. Const, art. T, § 5; Washington, Wash. Const, art. I, § 19; and Wyoming, Wy. Const, art. I, § 27. While few have faced reapportionment challenges, state courts have breathed meaning into these unique constitutional provisions, a few of which are set forth below by way of example. Specifically, last year, the Court of Chancery of Delaware, in an in-depth treatment of Delaware's Constitution, much like that engaged in by our Court today, considered a challenge to family-focused events at polling places on election day which induced parents of students to vote, but which operated as impediments to voting by the elderly and disabled. . In concluding such conduct violated the Delaware Constitution’s Elections Clause, the court reasoned that an election which provided a targeted group specific incentives to vote was neither free nor equal, noting the historical concerns in Delaware regarding the integrity of the election process. Young v. Red Clay Consolidated School, 159 A.3d 713, 758, 763 (Del. Ch. 2017).
      Even more apt, two states, Illinois and Ken-tubky, have long traditions regarding the application and interpretation of their elections clauses. In an early Illinois decision, the Illinois Supreme Court, considering a challenge to a congressional apportionment statute, cited to the Illinois Constitution and concluded: “[a]n election is free where the voters are exposed to no intimidation or improper influence and where each voter is allowed to cast his ballot as his own conscience dictates. Elections are equal when the vote of each voter is equal in its influence upon the result to the vote of every other elector — where each ballot is as effective as every other ballot.” Moran v. Bowley, 347 Ill. 148, 179 N.E. 526, 531 (1932). Similarly, in an early Kentucky decision involving the lack of printed ballots leaving numerous voters unable to exercise the franchise, that state’s high court offered that “[t]he very purpose of elections is to obtain a full, fair, and free expression of the popular will upon the matter, whatever it may be, submitted to the people for their approval or rejection; and when any substantial, number of legal voters are, from any cause, denied the right to vote, the election is not free and equal, in the meaning of the [Kentucky] Con-stitution." Walbrecht v. Ingram, 164 Ky. 463, 175 S.W. 1022, 1026 (1915).
      Thus, other states with identical constitutional provisions have considered and applied their elections clauses to a variety of election challenges, providing important protections for their voters. While those states whose constitutions have identical "free and equal” language to that of the Pennsylvania Constitution have not addressed the identical issue before us today, they, and other states, have been willing to consider and invigorate their provisions similarly, providing an equal right to each citizen, on par with every other citizen, to elect their representatives.
     
      
      . Nothing herein is intended to suggest that congressional' district maps must not also comply with federal law, and, most specifically, the Voting Rights Act, 52 U.S.C. § 10301.
     
      
      . In her dissenting opinion, Justice Mundy inexplicably contends that our allowance for the possibility that a future challenge to a future plan might show dilution even though the neutral redistricting criteria were adhered to "undermines the conclusion” that there is a violation in this case. Dissenting Opinion (Mundy, J.) at 835. However, as we state aboye, and as we discuss further below, assessment of those criteria fully, and solely, supports our conclusion in this case.
     
      
      . Dr. Chen also credibly rebutted the notion that the 2011 Plan’s outlier status derived from a hypothetical attempt to protect congressional incumbents — which attempt still, in any event, subordinated the traditional redistricting factors to others — or an attempt to establish the 2011 Plan's majority African-American district.
     
      
      . Indeed, the advent of advanced technology and increased computing power underlying Dr. Chen's compelling analysis shows such technology need not be employed, as the record shows herein, for illicit partisan gerrymandering. As discussed above, such tools will, just as powerfully, aid the legislature in performing its redistricting function in comportment with traditional redistricting factors and their constituents' constitutional rights, as-well as aiding courts in their evaluations of whether the legislature satisfied its obligations in this regard.
     
      
      . Indeed, the bulk of the 2011 Plan’s districts make then-Massachusetts Governor Elbridge Gerry’s eponymous 1812 partisan redistricting plan, criticized at the time for its salamander-like appearance — hence, "Gerrymander” — -and designed to dilute extant Federalist political power, appear relatively benign in comparison. See generally Jennifer Davis, "Elbridge Gerry and the Monstrous Gerrymander,” https://blogs.loc.gov/law/2017/ 02/elbridge-gerry-and-the-monstrous-gerrymander (Feb. 10, 2017).
     
      
      . Notably, in the last three congressional elections, voters in the 1st Congressional Dis- ’. trict elected a Democratic candidate with 84.9%, 82.8%, and 82.2% of the vote, respectively.
     
      
      . In the 2012 and 2014 congressional elections, voters in the 3rd Congressional District elected a Republican candidate with 57.1% and 60.6% of the vote, respectively, and, by 2016, the Republican candidate ran unopposed,
     
      
      . Justice Mundy, in her dissent, seemingly reads the federal Elections Clause in a vacuum, and, to the extent that she suggests an inability, or severely circumscribed ability, of state courts generally, or of our Court sub judies, to act, this approach has not been embraced or suggested by the United States Supreme Court or the Pennsylvania Supreme Court for over a half century. Indeed, to read the federal Constitution in a way that limits our Court in its power to remedy violations of our Commonwealth’s Constitution is misguided and directly contrary to bedrock notions of federalism embraced in our federal Constitution, and evinces a lack of respect for state rights. In sum, and as fully set forth above, in light of interpretations of the Elections Clause like that found in Growe — which encourage federal courts to defer to state redistricting efforts, including congressional redistricting, and expressly permit the judicial creation of redistricting maps when a legislature fails to act — as well as essential jurisprudential concepts of comity and federalism, it is beyond peradventure that state courts possess the authority to grant equitable remedies for constitutional violations, including the drawing of congressional maps (of course, subject to federal safeguards and, principally, the Voting Rights Act).
     
      
      . The Free and Equal Election Clause is set forth in full infra at 827.
     
      
      . Petitioners' argument on the Free and Equal Elections Clause appears to be tethered to their claim that the 2011 Plan violates the equal protection guarantees of the Pennsylvania Constitution provided in Article I, Sections 1 and 26. That being said, it is clear that Petitioners allege a violation of the Free and Equal Elections Clause, and thus, such claim is before the Court. Accordingly, I offer this opinion in response to the Majority’s analysis of that clause.
     
      
      . As I would not apply the finding of unconstitutionality to the May 2018 primary, I concur in Paragraph Sixth of the Court’s January 22nd Order allowing the March 2018 special election in Pennsylvania’s 18th Congressional District to be held under the 2011 Plan.
     
      
      . Article I, Section 4 of the United States Constitution is set forth in relevant part infra at 826.
     
      
      .To be precise, I concur in the Majority’s comprehensive recitation of the background of this case in Part I, the description of this action in Part II, Part Ill’s summary of the thorough proceedings in the Commonwealth Court including the factual findings and conclusions of law of Judge Brobson, and the presentation of the parties’ and amici’s arguments in Part IV. As said, I concur with the Majority’s analysis of the Free and Equal Election Clause in Part V. A. I dissent, however, from Part V. B, which I view as requiring the Legislature to utilize specified districting criteria in drafting a redistricting map, and concur only in the holding of Part V. C that the 2011 Plan is unconstitutional. Finally, I dissent to the remedy provided in Part VI,
     
      
      . I’agree with the Majority that Pennsylvania’s congressional districts must also meet the requirements set forth by the federal Constitution and related statutory enactments.
     
      
      . Indeed, Professor Nathaniel Persily, the expert this Court engaged in its Order of January 26th, has observed that "[a] quick plan, however, is not necessarily a good plan. Indeed, a computer can draw a statewide equi-populous plan by itself in a matter of hours or even minutes, but it is unlikely to be one a court (or anyone) would want to adopt.” Nathaniel Persily, When Judges Carve Democracies: A Primer on Court-Drawm Redistricting ■Plans, 73 Geo. Wash. L, Rev. 1131, 1147 (2005). A good redistricting plan takes time and thoughtful consideration by legislators who know the communities impacted by the plan.
     
      
      . Despite my disagreement with the remedy provided, I concur with the Majority’s clarification that, if the Legislature and the Governor agree to a plan, then this Court’s “role in this matter concludes, unless and until the constitutionality of the plan is challenged.” Maj. Op. at 822.
     
      
      .In contrast, Professor Persily has previously recommended that an ideal timeframe would provide for a court to begin drawing a' map three months prior to the beginning of ballot qualification, allowing one month for development of the map and one month for hearings on the proposed map. Persily, 73 Geo. Wash. L. Rev. at 1147-48. He additionally observes that a reasonable goal would provide for "releasing the final version of a plan one month prior to the beginning of the petitioning period” to "give potential candidates sufficient notice as to the location of their districts and a reasonable time to decide whether they wish to run.” Id. at 1147 n.88.
     
      
      . See generally Vieth, 541 U.S. at 274-77, 124 S.Ct. at 1774-76 (discussing the history of political gerrymandering in the United States); id. at 285, 124 S.Ct. at 1781 ("The Constitution clearly contemplates districting by political entities, and unsurprisingly that turns out to be root-and-branch a matter of politics.”); id. at 344, 124 S.Ct. at 1815 (Souter, J.) (observing "some intent to gain political advantage is inescapable whenever political bodies devise a district plan, and some effect results from the intent”); id. at 358, 124 S.Ct. at 1823 (Breyer, J.) (explaining that "political considerations will likely play an important, and proper, role in the drawing of district boundaries”); Gaffney v. Cummings, 412 U.S. 735, 753, 93 S.Ct. 2321, 2331, 37 L.Ed.2d 298 (1973) ("Politics and political considerations are inseparable from district-ing and apportionment.”).
     
      
      . Cf. Vieth, 541 U.S. at 360,124 S.Ct. at 1824 (Breyer, J„ dissenting) (depicting traditional or historically based voting-district boundaries as “an uneasy truce, sanctioned by tradition, among different parties seeking political advantage”),
     
      
      . I am in no way suggesting that the factors prioritized by the majority are not traditional districting criteria or that they lack relevance to the claims of discrimination. My concern is with the manner in which the majority rigidities these factors in the congressional redistricting context.
      In this regard, the majority’s standard would seem to operate more stringently than that suggested by Petitioners themselves, who urge this Court to set forth a test under Article I, Section 5 embodying a more conventional equal protection litmus — that is, one in which a challenger may prevail by demonstrating an intent to discriminate combined with a discriminatory effect. See Brief for Petitioners at 68 (stating this Court should adopt a standard whereby the challenger must show "intentional discrimination plus [a changed] outcome of an actual congressional election”).
      It is also not clear whether the requirement devised by the majority, as applied to state legislative reapportionment, would alter the review in the relevant line of cases. For example, I suspect that the state congressional redistricting plan approved in this Court’s Holt decision would fail under the new regime imposed by the majority, since, there, the Court found that the challengers had not established that a reapportionment plan encompassing numerous political-subdivision splits violated Article II, Section 16 of the Pennsylvania Constitution. See Holt, 620 Pa. at 383, 67 A.3d at 1217 (explaining that the unsuccessful challenge to the 2012 state legislative reapportionment plan,was brought by voters "who live in the Commonwealth’s wards, municipalities, and counties the [2012 Final Plan] split, often multiple times, to form Senate and House of Representatives Districts”), This cirtíumstance appears particularly troublesome because, although the state charter speaks directly to .the constraints for state legislative districts, it does riot mention congressional districts at all.'
     
      
      . ■ Notably, this Court has previously recognized the more limited significance of the Article II, Section 16 factors relative to congressional redistricting. See Erfer v. Common
        wealth, 568 Pa. 128, 142 n.4, 794 A.2d 325, 334 n.4 (2002).
      
     
      
      . The Majority does not say whether any Court-created map remains in effect just through the 2018 elections, also through 2020, and any special elections that may arise in between, until after the 2020 census, or some other point in time,
     
      
      . The Supreme Court has described the Elections Clause as broad in scope, but has also noted it is a specific grant of power to the States directly. Cook v. Gralike, 531 U.S. 510, 523, 121 S.Ct. 1029, 149 L.Ed.2d 44 (2001). The power of the States to regulate federal elections does not arise as a power “reserved” to the States under the Tenth Amendment. Id.; see also, e.g., U.S. Const, amend. X. In other words, “the States may regulate the incidents- of such elections ... only within the exclusive delegation of power under the Elections Clause,” Cook, 531 U.S. at 523, 121 S.Ct. 1029.
      In discussing “state rights” and "federalism,” the Majority, appears to operate on the assumption that a state legislature’s redistricting authority over federal elections is indeed such a Tenth Amendment power, Majority Op. at 824 n.79.- However, other- than the Elections Clause, "[n]o other constitutional provision gives the States authority over congressional elections, and no such authority could be reserved under the Tenth Amendment.” Cook, 531 U.S. at 522-23, 121 S.Ct. 1029. The Elections'Clause is’both an express grant of,, and a limitation on, the power of state governments in federal elections, including the judiciary, and as I discuss infra, the cases cited by the Majority are not "concrete” and do not form “a bedrock foundation.” Majority Op. at 822, 824. This is not reading the Elections Clause “in a vacuum.” Id. at 824 n.79. ‘
     
      
      .The Majority misconstrues my view of the Elections Clause,' See Majority Op. at 824 n.79. If this Court concluded that a congressional map was unconstitutional, and if the General Assembly was given sufficient time to act (which is not the case here) and it fails to act, a circumstance may arise where this Court could draw a map on a temporary remedial basis pending further state or federal legislative action. But it is quite another matter for this Court to put the General Assembly on a three-week timeline without articulating the complete criteria necessary to . be constitutionally compliant.
     
      
      . Indeed, the cases cited in Scott as examples of state judicial intervention only pertain to state legislative districts. See Scott, 381 U.S: at 409, 85 S.Ct. 1525 (collecting cases).
     
      
      . Generally, under Pullman abstention, named for R.R. Comm'n of Tex. v. Pullman Co., 312 U.S. 496, 61 S.Ct. 643, 85 L.Ed. 971 (1941), a federal court is required to defer to pending state court litigation “when a constitutional issue in the federal action will be mooted or presented in a different posture following conclusion of the state-court case.” Growe, 507 U.S. at 32, 113 S.Ct. 1075.
     
      
      . Indeed, the Court explicitly stated that after the Supreme Court of Minnesota adopted its own redistricting plan, the federal district court would then be permitted to resolve any and all .claims regarding the state court's plan. Growe, 507 U.S. at 36, 113 S.Ct. 1075.
     
      
      . Eleven years later, Justice Scalia dissented from the Court denying certiorari in Colo. Gen. Assembly v. Salazar, 541 U.S. 1093, 124 S.Ct. 2228, 159 L.Ed.2d 260 (2004), which presented this very question of whether the Elections Clause permits congressional maps drawn by state courts. While I recognize such dissents are of limited value, my point is only that it would seem odd for Justice Scalia to affirmatively wish for the Court to decide a constitutional question that he himself had supposedly just decided 11 years prior.
     
      
      . In Agre v. Wolf, 284 F.Supp.3d 591, 2018 WL 351603 (E.D. Pa. 2018), a federal court action was filed in the Eastern District of Pennsylvania, challenging the same congressional map that is before us in this case. On January 10, 2018, a three-judge district court entered judgment in favor of the state legislative and executive named defendants, There is an appeal currently pending.
     
      
      
        .Branch, also authored by Justice Scalia, dealt with a federal court-authored congressional map for Mississippi’s districts following the 2000 census. The Court observed that Congress enacted 2 U.S.C. § 2c to require single-member congressional districts, the boundaries of which "shall be established by law.” 2 U.S.C. § 2c, Branch observed that this express congressional authorization, also authorized state and federal courts to enforce its mandate. Branch, 538 U.S. at 272, 123 S.Ct. 1429. Interestingly, Branch also declined to address the district court’s separate conclusion that a state-court-drawn map was unconstitutional under the Elections Clause. Id. at 265, 123 S.Ct. 1429. In any event, there is no alleged violation of Section 2c in this case, nor is there any other congressional statute addressing partisan considerations in congressional districting.
