   OPINION

JUSTICE WECHT

In 2002, David Chmiel was convicted and sentenced to death for the murder of three elderly siblings. At Chmiel’s 2002 trial, the Commonwealth relied upon, the testimony of a state police forensic examiner, who opined that hair found at the crime scene was microscopically similar to Chmiel’s hair. On April 20,- 2015, the Federal Bureau of Investigation (“FBI”) issued a. press release admitting, for the first time, that testimony by FBI analysts regarding microscopic hair analysis in criminal trials, was erroneous. in the yast .majority of cases (hereinafter, “FBI press release”). The FBI further admitted that it had, over the course of twenty-five years, conducted multiple training courses for state and local forensic examiners throughout the country that'incorporated some of the same flawed language that the FBI examiners had used in lab reports and trial testimony. Appendix C at 2.

On June 18, 2015, Chmiel filed a petition pursuant to the PCRA, asserting that his conviction and death sentence rested upon unreliable microscopic hair comparison evidence. Recognizing that his petition facially was untimely, Chmiel asserted that the FBI press release constituted a newly discovered fact that satisfied the timeliness exception set forth in Section 9545(b)(l)(ii). The PCRA court rejected ChmieFs reliance upon the FBI press release as a newly discovered fact, and dismissed the petition as untimely. We reverse, and we remand for further proceedings.

George Surma was a Pennsylvania State Police (“PSP”) forensic scientist who testified for the Commonwealth at Chmiel’s trial. At that time, Surma had been a forensic scientist with the PSP for twenty-seven years and had testified as an expert in forensic microscopy or electrophoresis on three to four hundred prior occasions. Commonwealth v. Chmiel, 612 Pa. 333, 30 A.3d 1111, 1137 (2011) (“Chmiel II”); Notes of Testimony (“N.T.”), 8/27/2002, at 5-6. Surma testified that he had received extensive training in the field of forensic science and had engaged in “advanced work in the analysis of blood, electrophoresis of blood and miscroscopy.” Id. at 5.

Surma microscopically analyzed six hairs retrieved from a sweater sleeve mask that was found at the crime scene. This mask had been cut from a sweater and used to conceal the intruder’s identity during the murders. Commonwealth v. Chmiel, 585 Pa. 547, 889 A.2d 501, 510 (2005) (“Chmiel I”). The police were able to trace the sweater sleeve mask to Martin Chmiel, Chmiel’s brother. Id. At trial, Surma testified that he used a comparison microscope to detect up to fourteen possible features of the cuticle, cortex, and medulla of the hair. Chmiel II, 30 A.3d at 1124; N.T., 8/27/2002, at 14-23. Surma subjectively selected these fourteen bases of comparison by considering “whatever features or characteristics [he found] in that particular hair.” Id. at 19. Surma did not explain how many features had to be similar to warrant a conclusion of microscopic similarity, or dissimilar to preclude such a conclusion. Nevertheless, Surma concluded that two hairs found on the sweater sleeve mask were “microscopically similar” to hair samples obtained from Chmiel, but not to those obtained from Chmiel’s brother, Martin, or to the victims. Chmiel II, 30 A.3d at 1124; N.T., 8/27/2002, at 20, 26, 56. The prosecutor exaggerated Surma’s conclusions in his' opening and closing statements, promising a “microscopic match,” between Chmiel’s hairs and those found at the crime scenes N.T., 8/19/2002, at 79, and arguing that Surma’s testimony had established such a “match.” N.T., 9/6/2002, at 175-77.

On March 21, 2007, Chmiel filed his first PCRA petition. Chmiel raised numerous claims, including a claim that trial counsel was ineffective for failing to challenge the admissibility of Surma’s testimony pursuant to Frye v. United States, 293 F. 1013 (D.C. Cir. 1923), and for failing to obtain an expert witness to rebut. Surma’s testimony. Chmiel II, 30 A.3d at 1138. This Court found no merit to these ineffectiveness claims.

On June 18, 2015, Chmiel filed the present PCRA petition, asserting that his conviction and death sentence rested upon unreliable hair comparison evidence in violation of the Sixth, Eighth, and Fourteenth Amendments to the United States Constitution and Article I, Section 9 of the Pennsylvania Constitution. Chmiel also sought discovery from the Commonwealth pursuant to Pa.R.Crim.P. 902(E)(1).

Recognizing that his petition was untimely on its face, Chmiel relied upon the timeliness exception for newly discovered facts, 42 Pa.C.S. § 9545(b)(l)(ii), Chmiel asserted that his claim was predicated upon the April 20, 2015 FBI press release, and that he could not previously have ascertained the facts contained therein by the exercise of due diligence. As support for his position that the press release revealed newly discovered facts, Chmiel relied upon an April 18, 2015 article in The Washington Post about the FBI press release. Chmiel filed his PCRA petition within sixty days of the FBI press release. See 42 Pa.C.S. § 9545(b)(2). Because the FBI press release and the Washington Post article describing the FBI’s findings are the basis of Chmiel’s attempt to overcome the PCRA’s time restrictions, they warrant close review.

The FBI press release is entitled “FBI Testimony on Microscopic Hair Analysis Contained Errors in at Least 90 Percent of Cases in Ongoing Review.” Appendix C at 1. In the press release, the FBI publicly disclosed the initial findings of an ongoing investigation undertaken jointly by the Department of justice (“DOJ”), the FBI, the Innocence Project, and the National Association of Criminal Defense Lawyers (“NACDL”). The investigation scrutinized the testimony of FBI analysts concerning microscopic' hair comparison analysis prior to 2000, the point at which mitochondrial DNA testing became routine in the FBI. The review was prompted by exonerations of three men who had been convicted, in part, based upon the scientifically flawed testimony of three FBI hair examiners. The review encompassed cases in which FBI microscopic hair comparison was used to link a defendant to a crime in both the federal and state systems. The FBI concluded that its examiners’ testimony in at least 90% of cases contained erroneous statements. The FBI’s findings “confirm[ed], that the FBI microscopic hair analysts committed widespread, systematic error, grossly exaggerating the significance of their data under oath with the consequence of unfairly bolstering the prosecution’s case....” Appendix C at 1.

The FBI press release quoted, Peter Neufeld, co-director of the Innocence Project, as saying that the results of the FBI’s review demonstrated an “epic miscarriage of justice.” Id. The press release also quoted Norman L. Reimer, Executive Director of NACDL, as stating that, although “[i]t will be many months before we can know how many people were wrongly convicted based, on this flawed evidence," he was certain that there were “many whose liberty was deprived and lives destroyed by prosecutorial reliance on this flawed, albeit highly persuasive evidence.” Id, Mr. Reimer called upon lawmakers to prevent similar systemic failures, and upon the courts to “give those who were impacted by this evidence a second look at their convictions.” Id. The FBI committed to “addressing] errors made in' statements by FBI examiners regarding microscopic hair analysis in the context of testimony and laboratory reports.” Id.

The FBI press release also described the FBI’s efforts to train state and local hair, examiners in such “invalid” and “faulty” evidence:

Over the course of 25 years, the FBI conducted multiple two-week training courses that reached several hundred state and local hair examiners throughout the country and. that incorporated some of the same. scientifically flawed language that the FBI’s examiners had used in some lab reports and often in trial testimony. In response to the FBI/ DOJ review, the Texas Forensic Scientific Commission has already begun a review of cases handled by analysts at state and local crime labs. Similar audits are needed in most other states.

Id. at 2. The press release stated that the FBI’s review did. not include cases in which hair comparison was conducted by state and local crime labs. The findings prompted the FBI to commit to “[s]trongly encouraging] the states again to conduct their own independent reviews where its examiners were trained by the FBI.” Id.

The April 18, 2015 edition of The Washington Post reported upon the FBI’s findings in an article entitled “FBI admits flaws in hair analysis over decades.” See Appendix B. The article reported that the FBI and DOJ formally had acknowledged that “nearly every examiner in an elite FBI forensic unit gave flawed testimony in almost all trials in which.they offered evidence against criminal defendants over more than a two-decade period before 2000.” Id. at 1. The Washington Post quoted legal analysts as characterizing the FBI’s review as “a watershed in one of the country’s largest forensic scandals, highlighting the .failure of the nation’s courts for decades to keep bogus scientific information from juries. ...” Id. The questions following the FBI’s review, according to the article, included how the courts will respond to findings that “confirm long-suspected problems with subjective, pattern-based 'forensic techniques — like hair and bite-mark comparisons — that have contributed to wrongful convictions in more than one-quarter of 329 DNA-exoneration cases since 19891” Id. The article indicated that, although “unnamed federal officials previously acknowledged widespread problems, the FBI until now has withheld comment because findings might not be representative.” Id. at 2.

The Washington Post article explained that, until 2012, hair examiners lacked written standards defining scientifically accurate ways to explain hair analysis results in court. Prior to such standards, FBI hair analysts routinely testified to the “near-certainty of ‘matches’ of crime scene hairs,” id. at 2, supporting their conclusions with incomplete or misleading statistics. Id. In truth, there' was no accepted research on the frequency with which hah’ from different individuals may appear the same. According to the article, warnings about the problems with hair analysis had been mounting since 2002, when the FBI reported that its own DNA testing revealed that examiners reported false hair matches 11% of the time. Id, at 3. Like the FBI press release, the article reported that “the same FBI examiners whose work is under review taught 500 to 1,000 state and local crime lab analysts to testify in the same ways.” Id. at 3-4.

Relying upon the FBI press release to satisfy the PCRA’s newly discovered facts exception, Chmiel asserted in his petition that Surma was trained by the FBI and provided the same scientifically unsupportable testimony that the FBI now disclaims, linking the hairs recovered from the sweater sleeve mask to Chmiel, while also ■excluding Martin Chmiel. In tandem with his PCRA petition, Chmiel sought discovery pursuant to Rule 902(E)(1), which provides that “no discovery shall be permitted at any stage of the proceedings, except upon leave of court after a showing of exceptional circumstances.” Pa.R.Crim.P. 902(E)(1). Chmiel asserted that he had established exceptional circumstances to depose Surma, to take discovery regarding every other case in which Surma had testified, and to obtain documentary evidence in the FBI’s possession regarding the FBI’s internal review of 'the use of hair comparison evidence.

The PCRA court dismissed Chmiel’s PCRA petition as untimely. According to the PCRA court, our decision in Commonwealth v. Edmiston, 619 Pa. 549, 65 A.3d 339 (2013), controlled the timeliness inquiry. Edmiston involved a PCRA petition filed by a capital defendant who, like Chmiel, was convicted following the introduction of hair comparison analysis testimony at trial. On February 18, 2009, the National Academy of Sciences published a report entitled “Strengthening Forensic Science in the United States: A Path Forward” (hereinafter, “the NAS Report”). The NAS Report was.a.review of prior studies and articles, as well as the National Academy of Sciences’ conclusion that “there was no scientific support for the use of microscopic hair analysis for individualization that is not accompanied by mitochondrial DNA analysis.” Edmiston, 65 A.3d at 351.

On April 17, 2009, Edmiston raised a facially untimely claim for post-conviction relief premised upon the NAS Report. Edmiston, 65 A.3d at 344. Edmiston relied upon the NAS Report in attempting to establish the newly discovered fact exception to the one-year time bar. Edmiston, 65 A.3d at 360-51; 42 Pa.C.S'. § 9545(b)(1)(h). Edmiston asserted that the NAS Report was a newly discovered fact that supported his claim of actual innocence, because it demonstrated that the Commonwealth’s ■ hair analysis ' evidence was “false, misleading, and unreliable.” Edmiston, 65 A.3d at 351.

On appeal from the PCRA court’s dismissal of Edmiston’s petition as untimely, this Court addressed the applicability of the newly discovered facts exception to the PCRA’s jurisdictional time ' restrictions. See 42 Pa.C.S. § 9545(b)(1)(h). We observed that, “to constitute facts which, were unknown to a petitioner and could not have been ascertained by the exercise of due diligence, the information must not be of public record and must not be facts that were previously known but are now presented through a newly discovered source.” Edmiston, 65 A.3d at 352. Evaluating Edmiston’s reliance upon the NAS Report as a newly discovered fact, this Court explained that “the ‘fact’ [that Ed-miston] relies upon as newly discovered is not the publication of the NAS Report, but the analysis of the scientific principles supporting hair comparison analysis.” Id. This Court held that the “fact” contained within the NAS Report was not new, as questions about the reliability of hair comparison analysis had existed in various sources pri- or to publication of the NAS Report: “Specifically, the NAS Report refers to various studies and reports published in the public domain as early as 1974 and as recently as 2007. As such, the information relied upon by [Edmiston] in the Report constitutes facts that were in the public domain and could have been discovered by [Edmiston] through the exercise of due diligence prior to the filing of his ... Petition.” Edmiston, 65 A.3d at 352. This analysis led the Court to conclude that the NAS Report failed to satisfy the timeliness exception for newly discovered facts.

In the instant case, the PCRA court analogized the FBI press release to the NA£[ Report in Edmiston, reasoning that the information contained within the FBI press release was available in the public domain prior to 2015, and that Chmiel could have discovered it through the exercise of due diligence more than sixty days prior to filing the PCRA petition on June 18, 2015. In particular, the PCRA court relied upon an article from the Washington Post dated April 16, 2012, reporting that the DOJ had begun to review internally numerous cases after reports that sloppy work by FBI forensic examiners were producing unreliable hair comparison evidence at trials. PCRA Court Opinion at 28-29. The article reported that the DOJ had disclosed the results of the review to the defendants in fewer than half of approximately “250-plus questioned cases” included in the review. Id. at 29. On July 10, 2012, the Washington Post confirmed that the DOJ and FBI had launched a review of thousands of criminal cases that included microscopic hair examination by the FBI. On July 29, 2014, the Washington Post reported that the DOJ and the FBI were in the midst of their internal review, that most of the cases under review included flawed forensic testimony from the FBI, and that the DOJ had begun to notify affected defendants. Id. at 30-31.

Assuming, arguendo, that the FBI press release satisfied the timeliness exception for newly discovered facts, the PCRA court held that Chmiel was not entitled to relief because his claim was previously litigated. See 42 Pa.C.S. § 9544(a)(3). According to the PCRA court, Chmiel already had challenged the scientific validity of Surma’s hair comparison evidence and methodology in his prior PCRA petition, when he raised a claim of counsel ineffectiveness for failing to move for exclusion of such evidence pursuant to Frye, and for failing to hire an expert to counter Sur-ma’s testimony. Finally, the PCRA court held that Chmiel had failed to establish exceptional circumstances to warrant discovery pursuant to Rule 902(E)(1).

We have exclusive jurisdiction over appeals of determinations made in death penalty cases. 42 Pa.C.S. § 722(4); 42 Pa.C.S. § 9546(d). “Our review of a PCRA court’s decision is limited to examining whether the PCRA court’s findings of fact are supported by the record, and whether its conclusions of law are free from legal error.” Commonwealth v. Koehler, 614 Pa. 159, 36 A.3d 121, 131 (2012). Our review of questions of law is de novo. Commonwealth v. Fahy, 598 Pa. 584, 959 A.2d 312, 316 (2008). Our scope of review is limited to the PCRA court’s findings and the evidence of record, viewed in the light most favorable to the Commonwealth as the prevailing party. Id.

To be eligible for post-conviction relief, a petitioner must prove by a preponderance of the evidence that his conviction or sentence resulted from one of several enumerated circumstances, see 42 Pa.C.S. § 9543(a)(2), and that the issues have not been previously litigated or waived, id. § 9543(a)(3). “A PCRA petition, including a second or subsequent petition, must be filed within one year of a final judgment, unless the petitioner alleges and proves that he is entitled to one of three exceptions to this general rule, and that the petition was filed within 60 days of the date the claim could have been presented.” Edmiston, 65 A.3d at 345; 42 Pa.C.S. § 9545(b). This is a jurisdictional limitation. Commonwealth v. Bennett, 593 Pa. 382, 930 A.2d 1264, 1267 (2007).

As noted, Chmiel relies upon the timeliness exception for newly discovered facts. See 42 Pa.C.S. § 9545(b)(l)(ii). This exception “requires that the ‘facts’ upon which such a claim is predicated must not have been known to appellant, nor could they have been ascertained by due diligence.” Commonwealth v. Lambert, 584 Pa. 461, 884 A.2d 848, 852 (2005). As this Court explained in Edmiston, to fall within this exception, the factual predicate of the claim “must not be of public record and must not be facts that were previously known but are now presented through a newly discovered source.” Edmiston, 65 A.3d at 352.

The PCRA court narrowly construed the newly discovered facts exception in holding that the underlying information contained in the FBI press release was simply confirmation of information that was already available in the public domain. In this conclusion, the PCRA court erred.

There are two newly discovered facts upon which Chmiel’s underlying claim is predicated, both of which were made public for the first time in the Washington Post article and the FBI press release. First, the FBI' publicly admitted that the testimony and statements provided by its analysts about microscopic hair comparison analysis were erroneous in the vast majority of cases. The FBI’s revelation reverberated throughout' the country, marking a “watershed in one of the country’s largest forensic scandals,” see Appendix B at 1, precisely because it constituted a public admission by the government agency that had propounded the widespread use of such scientifically flawed testimony. The revelation was the first time the FBI acknowledged that its microscopic hair analysts committed widespread, systemic error by grossly exaggerating the significance of their data in criminal trials. The Washington Post article acknowledged the novelty of the FBI’s disclosures: “While unnamed federal officials previously acknowledged widespread problems, the FBI until now has withheld comment because findings might not be representative.” See Appendix B at 2. Second, the FBI press release included the revelation that the FBI had trained many state and local analysts to provide the same scientifically flawed opinions in state criminal trials.

With these newly discovered, material facts, the FBI press release indicates that Surma’s trial testimony may have exceeded the limits of science and overstated to the jury the significance of the microscopic hair analysis. Surma used microscopic hair analysis in an attempt to link Chmiel to the crime. The FBI now has publicly repudiated, the use of microscopic hair analysis to “link a criminal defendant to a crime.” See Appendix C at 1. The FBI’s repudiation and disclosure about its role in training state and local forensic examiners satisfies Section 9545(b)(l)(ii), and entitles Chmiel to a merits determination of his underlying claim.

Contrary to the PCRA court’s opinion and the dissenting opinion by Justice Mun-dy, see Dissenting Opinion at 632-33, the fact that the FBI was internally reviewing the accuracy of microscopic hair analysis or testimony is not the newly discovered fact upon which Chmiel’s claim is based. Rather, the newly discovered facts are the FBI’s admissions, as the proponent of microscopic hair analysis, that its examiners gave flawed and scientifically unsupportable testimony, and spread its flawed methodology to state and local analysts. Although the existence of the FBI’s internal investigation was known, the press release marked the first public admission by the FBI regarding its conclusions about testimony premised upon microscopic hair analysis and the dissemination of such scientifically flawed language to state and local analysts.

Moreover, this Court’s analysis of the NAS Report in Edmiston does not control the timeliness of Chmiel’s second PCRA petition. With respect to hair analysis, “the [NAS] Report reviewed prior studies and articles , to conclude that there was no scientific support for the use of microscopic hair analysis for individualization that is not accompanied by mitochondrial DNA analysis.” Edmiston, 65 A.3d at 351. This Court concluded that the facts proffered in the. NAS Report were not new, and had existed in various sources prior to publicar tion of the report.

Although , the NAS Report compiled preexisting public data and studies and questioned the science underlying microscopic hair analysis, it unquestionably was not an admission by .the authority behind the science that the science and related testimony were, in fact, flawed. In contrast, the FBI press release is not old wine in a new bottle, see Appellant’s Brief at 17; it was a public admission by the FBI, as the nation’s premier law enforcement agency and the proponent of this forensic technique, of widespread error. It is this concession, not the suspected unreliability of the forensic evidence as developed through scientific advancements, that triggers the sixty-day window within which Ghmiel was required to file his claim. This concession did' not exist in* the public domain prior to April 20, 2015.

The accepted understanding in the forensic science community of microscopic hair comparison analysis has shifted since Chmiel’s conviction. This shift in understanding reveals a recognition of the flawed scientific premise that microscopic hair comparison could be used definitively to link a criminal defendant to a crime. Although the scientific foundation of such conclusory assertions was called into question beginning as early as 1974, Edmiston, 65 A.3d at 352, and continually thereafter, this substantial shift in understanding was not embraced or acknowledged by the FBI until it went public with the preliminary results of its independent review. Scientific breakthroughs in rejecting the ability of a forensic hair analyst to opine about statistical significance, or to link a defendant to a crime, reached a tipping point with the 2009 NAS Report. At that time, however, the FBI remained' silent on the reliability of what it now concedes is “invalid,” “flawed,” and “faulty” evidence. See Appendix C at 1-2. The FBI’s view in April 2015 stands in sharp contrast to its flawed understanding of the significance of microscopic hair comparison analysis in the early 2000s.

-Nor are Ghmiel’s claims previously litigated, as' the PCRA court held. Section 9543(a)(3) of the PCRA provides that “an issue” has been previously litigated if “the highest appellate court in which the petitioner could have had review as a matter of right has ruled on the merits of the issue.” 42 Pa.C.S. § 9544(a)(2); Commonwealth v. Beasley, 544 Pa. 554, 678 A.2d 773, 778 (1996). In this context, “issue” is “the discrete legal ground” that was forwarded to the highest - appellate court and which would have entitled the defendant to relief. Commonwealth v. Collins, 585 Pa. 45, 888 A.2d 564, 570 (2005). Although there can be many theories and allegations in support'of a single issue, Section 9544 refers to the discrete legal ground already raised and decided. Id. An issue is not previously litigated when it does not rely solely upon previously litigated evidence. Commonwealth v. Miller, 560 Pa. 500, 746 A.2d 592, 602 n.9 & 10 (2000).

In his first PCRA petition,. Chmiel argued that .his counsel was ineffective for failing to challenge the admissibility of Surma’s testimony pursuant to Frye, and for failing to rebut Surma’s testimony with an expert witness. Chmiel II, 30 A.3d at 1138. In support of this claim, Chmiel presented a forensic chemical microscopist, Samuel James Palenik. Palenik testified that, although’ microscopic hair analysis has value as an investigative tool, it cannot be used for positive identification. Id. at 1139. Palenik also testified about the flaws in Surma’s procedures. For example, Pal-enik testified that Surma’s findings were not verified by an independent microscopist as was required by the' industry guidelines that were in existence at the time of Chmiel’s trial. Chmiel also supported his claim by relying upon a series of forensic science journals, law review articles, and newspaper reports disputing the accuracy of hair comparison evidence’. Chmiel included an FBI study comparing microscopic hair analysis to mitochondrial DNA analysis, and identifying error rates for microscopic hair analysis.

The Frye test is essentially a.-test for the admissibility of novel science, providing that the “[a]dmissibility .of [ ] scientific evidence depends upon the general acceptance of its validity by those scientists active in the field to- which the evidence belongs.” Commonwealth v. Dengler, 586 Pa. 54, 890 A.2d 372, 381 (2005) (quoting Commonwealth v. Topa, 471 Pa. 223, 369 A.2d 1277, 1281 (1977)). Chmiel’s prior post-conviction attack on the Commonwealth’s hair analysis evidence was a challenge to the admissibility of the science of hair microscopy, and to counsel’s failure to challenge the admissibility on this basis. Chmiel II, 30 A.3d at 1141. In rejecting his ineffectiveness claim, this Court observed that “many jurisdictions [], prior to [Chmiel’s] 2002 trial, had determined that human hair analysis by microscopical comparison is an accepted and reliable scientific method or technique.” Chmiel II, 30 A.3d at 1141. We were careful not to “discredit the notion ... that a once-viable science may lose its wide acceptance in the scientific community ....” Chmiel II, 30 A.3d at 1142. Our rejection of Chmiel’s claim was premised upon the lack of support for his view that, at the time of his 2002 trial, forensic hair microscopy was no longer an accepted science. Id. Indeed, at the time of Chmiel’s 2008 PCRA hearing, Palenik relied upon the same scientific methodology as did Surma to testify that hair microscopy was a recognized science to which a “minimal reserve of experts ... exists who can critically examine the validity of a scientific determination in a particular case.” Id. (quoting Dengler, 890 A.2d at 381 (describing one of the principal concerns of Frye)). We found no merit to Chmiel’s Frye-based ineffectiveness claim.

Chmiel’s current claim is premised upon the fact that, since the FBI’s April 20, 2015 admission, microscopic hair analysis no longer is considered to be scientifically reliable. This issue does not rest upon the evidence and arguments made in Chmiel’s prior PCRA ineffectiveness claim. Chmiel’s prior PCRA claim and the current claim are premised upon discrete legal grounds. See Collins, 888 A.2d at 570. The current claim is not previously litigated.

Accordingly, the information contained within the FBI’s press release did not exist in the public domain prior to publication of the press release. The FBI’s concessions in its press release triggered the sixty-day window within which Chmiel had to file his petition. See 42 Pa.C.S. § 9545(b)(2). Chmiel filed his petition within sixty days, on June 18, 2015. Accordingly, we reverse the order of the PCRA court dismissing Chmiel’s petition as untimely and previously litigated, and we remand for further proceedings.

CHIEF JUSTICE SAYLOR,

Concurring

I support the majority’s holding that jurisdiction lies. However, I have difficulty with the linchpin of its analysis, ie., that forensic examiner George Surma “used microscopic hair analysis in an attempt to link Chmiel to the crime[s]” of which he was accused, on the order of the linkage that has now been repudiated by the Federal Bureau of Investigation. Majority Opinion, at 625-26.

To the extent that the issue is whether Mr. Surma used hair comparison “definitively to link” Appellant to the crimes, id. at 626-27,1 do not believe that this is what occurred. In point of fact, the examiner explained to the jury that he could never say whether a particular hair derived from a specific person, see N.T., August 27, 2002, at 30; that he was engaged only in a “process of exclusion,” id., and that any hair sample could have the same microscopic characteristics as hair taken from multiple individuals. See id. at 31. Along these lines, Mr. Surma couched his conclusion in terms of the evidence-sample hairs being “a possible source from [Appellant’s] head.” See id. at 23.

As noted by a prominent commentator, the FBI’s revelations would appear to be “limited to the issue of overclaiming.” David H. Kaye, Ultracrepidarianism in Forensic Science: The Hair Evidence Debacle, 72 Wash. & Lee Rev. Online 227, 228-29 (2015). In other words, although the agency has disapproved the use of physical comparisons as definitive proof of identity, it has not discredited microscopic hair comparison analysis as “an entire invalid science.” Id. at 233, Indeed, the collaborators in the national review of criminal prosecutions in which such analysis was used have categorized the potential areas of concern as follows:

Error Type 1: The examiner stated or implied that the evidentiary hair could be associated with a specific individual to the exclusion of all others.
Error Type 2: The examiner assigned to the positive association a statistical weight or probability, or provided a likelihood that the questioned hair originated from a particular source, or rendered an opinion on the likelihood or rareness of the positive association that could lead the jury to believe that valid statistical weight can be assigned to a microscopic hair sample.
Error Type 3: The examiner cited the number of cases or hair analyses worked in the lab and the number of samples from different individuals that could not be distinguished from one another as a predictive value to bolster the conclusion that a hair belongs to a specific individual.

DOJ, 65 Forensic Science and Forensic Evidence I, at 6-7 (Jan. 2017). Notably, from my point of view at least, it would be difficult to attribute any of these errors to Mr. Surma’s testimony.

Despite the above reservations, I join the balance of the majority’s analysis on the basis of Commonwealth v. Bennett, 593 Pa. 382, 930 A.2d 1264 (2007), which decoupled the “facts” contemplated by Section 9545(b)(ii) of the PCRA from the “claims” serving as the explicit bases for statutory post-conviction relief per Section 9543(a). See id. at 402-10, 930 A.2d at 1275-80 (Saylor, J., dissenting). In this regard, I agree with the majority’s determination that the FBI’s press release and attendant admissions constitute a newly discovered fact triggering jurisdiction under Bennett. As I understand Bennett, no further analysis concerning the relationship between the newly-discovered fact and the underlying merits-based claim is necessary or appropriate in the jurisdictional assessment. See id.

Finally, I observe that the liberal conferral of jurisdiction, in this instance, is consistent with the approach of conscientious prosecutors who are not opposing post-conviction review to determine whether criminal cases may have been affected by the acknowledged systemic error in the FBI’s practices. See FBI Press Release, FBI Testimony on Microscopic Hair Analysis Contained Emrs in at Least 90 Percent of Cases in Ongoing Review, at 2 (Apr. 20, 2015).

JUSTICE DONOHUE,

Concurring

I join in full the well-reasoned majority opinion of Justice Wecht. I write separately to express my concern for the dubious strategy employed by the Pennsylvania Attorney General’s Office in this matter. In its April 20, 2015 press release, the FBI publicly disclosed that examiners in its microscopic hair comparison' unit had routinely provided opinions lacking scientific basis, and that- it had trained many state and local analysts to provide such scientifically flawed opinions. Majority Op. at 619-20. Accordingly, Chmiel filed a discovery motion seeking to learn whether the Commonwealth’s testifying forensic examiner at his trial (George Surma) was a recipient of such FBI training. In response, in both the PCRA court and again in this Court, the Pennsylvania Attorney General’s Office vigorously opposed the discovery request, repeatedly emphasizing Chmiel’s lack of “any direct, evidence” that Surma was (or was not) trained- in microscopic hair analysis by the FBI and arguing that Chmiel’s claim of a newly discovered fact is thus “based on sheer conjecture and rank speculation.” .PCRA Court Opinion, 12/30/2015, at 24; Commonwealth’s Brief at 20. Baséd upon these arguments, the PCRA court denied the discovery motion.

Justice Wecht notes that on remand, the PCRA court should reconsider Chmiel’s discovery request in light of this Court’s timeliness decision. Majority Op. at 628 n.8. In my view, however, Chmiel should not be forced into the discovery process to obtain this described information, as whether or not Surma was trained by the FBI is clearly within the knowledge and control of the prosecutors, in the-Pennsylvania Attorney General’s Office litigating the present PCRA petition. If Surma in fact received FBI training, these prosecutors, knowing that Chmiel. had been convicted on the basis of expert testimony that has been established to be unreliable and not scientifically supportable, should have immediately and voluntarily provided the information to Chmiel’s defense lawyers.

In the FBI’s press release that forms the basis for Chmiel’s current PCRA petition, the United States Department of Justice indicated that in federal cases, it “will not raise procedural objections, such as statute of limitations and procedural default claims, in response to defendants’ petitions seeking a new trial because of the faulty evidence.” -The Pennsylvania Attorney General’s Office clearly has not adopted this approach, and because of the jurisdictional requirements in Pennsylvania’s Post Conviction Relief Act, 42 Pa. C.S. § 9545(b)(1), I take no umbrage with the Attorney General’s Office’s decision to litigate the legal issue of.the timeliness of Chmiel’s PCRA petition. I am, however, greatly troubled by its decisions, to refuse to disclose factual-information to Chmiel relevant to the PCRA petition; to oppose Chmiel’s attempts to obtain this informar tion through discovery; and then to use Chmiel’s lack of this information as a basis for opposing his request for a new trial. In my view, it is neither fair game nor appropriate for a prosecutor to base an argument on the defendant’s lack of information about a fact that is in the full knowledge and control of the prosecutor in an attempt to prevent'a new trial after a conviction based on junk science.

Prosecutors have a unique role in our criminal justice system. This Court has codified the “Special Responsibilities of a Prosecutor” to provide that “[a] prosecutor has the responsibility of a minister of justice and not simply that of an advocate.” Pennsylvania Rules of Professional Conduct 3.8 (comment). We have further observed that “[a] defendant does not have a right not to be prosecuted; he does, however, have a right to have his case reviewed by an administrator of justice with his mind on the public purpose, not by an advocate whose judgment may be blurred by subjective reasons.” Commonwealth v. Eskridge, 529 Pa. 387, 604 A.2d 700, 701 (1992) (citing Commonwealth v. Dunlap, 335 A.2d 364, 368 (Pa. Super. 1975) (Hoffman, J., dissenting)); see also Commonwealth v. Briggs, 608 Pa. 430, 12 A.3d 291, 331 (2011). As aptly stated by the United States Supreme Court,

[The prosecutor] is the representative not of an ordinary party to a controversy, but of a sovereignty whose obligation to govern impartially is as compelling as its obligation to govern at all; and whose interest, therefore, in a criminal prosecution is not that it shall win a case, but that justice shall be done.

Berger v. United States, 295 U.S. 78, 88, 55 S.Ct. 629, 79 L.Ed. 1314 (1935) (emphasis added); see also Brady v. Maryland, 373 U.S. 83, 87, 83 S.Ct. 1194, 10 L.Ed.2d 215 (1963) (“Society wins not only when the guilty are convicted but when criminal trials are fair; our system of the administration of justice suffers when any accused is treated unfairly.”).

The prosecutor’s duty to seek justice trumps his or her role as an advocate to win cases for the Commonwealth. See Jonathan A. Rapping, Who’s Guarding the Henhouse? How the American Prosecutor Came to Devour Those He is Sworn to Protect, WASHBURN L.J. 513, 518 (2012). As a result, the prosecutors in the Pennsylvania Attorney General’s Office had an ethical obligation to inform Chmiel’s defense counsel as to whether or not the Commonwealth’s testifying expert had been trained by the FBI. The decision not to do so, and to instead use Chmiel’s lack of this information as a basis for denying him a new trial, was in derogation of the role of the prosecutor as a minister of justice. The integrity of our criminal justice system depends on all of the players fulfilling their roles. In my view, in this case, the prosecutor fell well short of what is required.

JUSTICE MUNDY,

Dissenting

The Majority concludes that Appellant has satisfied his burden under the newly-discovered fact exception of the Post Conviction Relief Act’s (PCRA) time-bar. Specifically, the Court inherently holds that the April 20, 2015 joint press release by the FBI and other entities underlies Appellant’s constitutional and after-discovered evidence claims in his PCRA petition. Because I conclude an unrelated federal agency’s press release does not render timely under the PCRA a collateral attack on a state conviction obtained through scientific analysis conducted by a state employee, I respectfully dissent.

As this Court recently explained, “[wjhen considering a claim seeking to invoke section 9545(b)(l)(ii), the petitioner must establish only that (1) the facts upon which the claim was predicated were unknown and (2) they could not have been ascertained by the exercise of due diligence.” Commonwealth v. Cox, 636 Pa. 603, 146 A.3d 221, 227 (2016) (citation omitted). Furthermore, this Court has explained that “[d]ue diligence does not require perfect vigilance and punctilious care, but merely a showing the party has put forth reasonable effort to obtain the information upon which a claim is based.” Id. at 230 (quoting Commonwealth v. Edmiston, 619 Pa. 549, 65 A.3d 339, 348 (2013)).

The Majority agrees with Appellant that the joint press release contains two new facts. First, the FBI’s admission that its own experts provided scientifically flawed testimony. Appellant’s Brief at 16. In this regard, the Majority stresses that “[i]t is this concession, not the suspected unreliability of the forensic evidence as developed through scientific advancements, that triggers the sixty-day window within which [Appellant] was required to file his claim.” Majority Op. at 626. Second, the Majority highlights the FBI’s acknowledgement that it instructed various state analysts over the years in similar methods. Id. at 626.

By its plain text, the newly-discovered fact exception applies only to facts that are crucial to the underlying claims. See 42 Pa.C.S. § 9545(b)(l)(ii) (stating that a petition will be considered timely where “the facts upon which the claim is predicated were unknown to the petitioner and could not have been ascertained by the exercise of due diligence”) (emphasis added). Here, Appellant’s underlying claims in his PCRA petition are premised on the notion that forensic examiner George Surma’s hair microscopy testimony was inaccurate and inadmissible.

Throughout the pendency of this case, Appellant has challenged the accuracy of hair microscopy analysis. Most importantly, Appellant’s 2008 amended PCRA petition explicitly stated that “[a]n FBI study comparing microscopic and mitochondrial DNA analysis of hair found that the former was -wrong approximately twelve percent of the time.” Appellant’s Amended PCRA Petition, 6/30/08, at ¶ 291. Further, an April 16, 2012 Washington Post article specifically stated that the DOJ “started reviewing cases in the 1990s after reports of sloppy work by examiners at the FBI lab was producing unreliable forensic evidence in court trials.” Commonwealth’s Answer, 10/19/15, Exhibit A, at 1 (emphasis added). In addition, a July 10, 2012 Washington Post article noted the DOJ and FBI “launched a [new] review of thousands of criminal cases to determine whether any defendants were wrongfully convicted or deserve a new trial because of flawed forensic evidence[.]” Id. at Exhibit C, at 1. The review targeted over 10,000 “cases ... where a microscopic hair examination conducted by the FBI was among the evidence in a case that resulted in a conviction.” Id. The Washington Post followed up in its July 29, 2014 article stating, “[n]early every criminal case reviewed by the FBI and the [DOJ] as part of a massive investigation[,] started in 2012[,] of problems at the FBI lab has included flawed forensic testimony from the agency[.]” Id. at Exhibit D, at 1. Up to that point, “the FBI had reviewed about 160 cases[.]” Id. The article continued that the DOJ notified 23 defendants, which included 14 death-penalty prisoners in August 2013. All of these materials, at a minimum, reveal that the FBI and the DOJ had questioned hair microscopy analysis long before the April 20, 2015 joint press release.

The Majority does not dispute this, but emphasizes that the FBI’s admissions and conclusions in the joint press release are the newly-discovered facts. See Majority Op. at 626-27. It is the Majority’s view that these are the facts “upon which [Appellant’s] claim[s are] predicated[.]” 42 Pa. C.S. § 9545(b)(l)(ii). The Majority does not explain how these facts are any more specific to Appellant’s case than ones from his previous PCRA petition. For the FBI’s admissions and conclusions to be considered newly-discovered facts, it must also be true that these purported new facts are so essential that the instant PCRA petition could not have been filed any earlier even with the exercise of due diligence. See Cox, 146 A.3d at 227 (citation omitted). As I stress above, Appellant was before this very Court in 2011 claiming Surma’s analysis in Ms specific case was flawed and “junk science.” See Commonwealth v. Chmiel, 612 Pa. 333, 30 A.3d 1111, 1137-42 (2011); Appellant’s Amended PCRA Petition, 6/30/08, at ¶291. The Majority cites no legal authority for the proposition that the FBI’s agreement with Appellant as to the science is an essential factual predicate to a legal claim for relief in a case where the FBI was not involved. See Majority Op. at 626-27. Absent a direct connection between the FBI’s press release and Appellant’s claim, I cannot agree that Appellant has met his burden under Section 9545(b)(1)(h). See Cox, 146 A.3d at 227.

Based on the foregoing, I conclude the PCRA court properly determined that Appellant’s petition was untimely filed, and the court lacked jurisdiction to address his claims. See id. Because I would affirm the order of the PCRA court, I respectfully dissent.

      . To the extent Chief Justice Saylor'believes that Surma’s testimony may in fact not have constituted the type of junk science that the FBI now has repudiated, see Concurring Opinion at 628-29, those considerations go to the merits of the underlying issue rather than to the timeliness of the PCRA petition. See Concurring Opinion at 629-30; Commonwealth v. Bennett, 593 Pa. 382, 930 A.2d 1264, 1271 (2007) ("the exception set forth in subsection (b)(l)(ii) does not require any merits analysis of the underlying claim.”).
      We disagree with Justice Mundy’s position that Chmiel must, at this juncture, demonstrate a more "direct connection” between the FBI press release and his underlying claim. See Dissenting Opinion at 633. Chmiel’s underlying claim is that his conviction rests upon unreliable hair comparison evidence in violation of the United States and Pennsylvania Constitutions. Pursuant to Bennett, all that Chmiel must demonstrate is that “1) ‘the facts upon which the claim was predicated were unknown’ and 2) ‘could not have been ascertained by the exercise of due diligence.’ ” Bennett, 930 A.2d at 1272 (citing 42 Pa.C.S. § 9545(b)( 1 )(ii)). As explained above, Chmiel’s claim is predicated upon the newly discovered facts contained within the FBI press release. Such facts could not have-been ascertained by the exercise of due diligence prior to the issuance of the FBI press release.
     
      
      . The PCRA court denied Chmiel’s request for discovery to ascertain whether Surma was trained by the FBI based upon its ruling that the underlying claim was time-barred. To the extent this question is necessary to resolve the merits of Chmiel’s underlying claim, the PCRA court should reconsider the discovery request in light of our timeliness conclusion.
     
      
      . As Appellant emphasizes, the prosecutor may have engaged in overclaiming, inter alia, via his assertion in his closing remarks that Mr. Surma’s testimony depicted that the two evidence-sample hairs "match[ed] up to” Appellant's hair. N.T., Sept. 6, 2002, at 175. However, any misstatements the prosecutor may have made to the jury concerning what Mr. Surma had said are not after-discovered facts, since they have been readily available for review since the time of trial.
      Significantly, as well, the collaborators' concerns do not appear to be with the use of microscopic hair comparison analysis as a means of exclusion, as occurred relative to Appellant's brother.
     
      
      . Surma’s trial testimony suggests to the contrary. When asked, "If you went to the FBI, the crime lab down there, would they be able to do anything different from what you were ■ doing,” Surma responded, "They-would have done basically what I did.” N.T., 10/16— 29/1984, Vol. II at 1381. This testimony provides a basis for concluding that Surma may have learned the microscopic hair comparison techniques he employed in this case from FBI training.

      . I point out this flaw in Appellant's argument not to show that his claims are previously litigated within the meaning of the PCRA, but rather to show that the FBI’s admissions are not a necessary predicate for Appellant to litigate his specific claims.
     
      
      . In addition, I agree with the Commonwealth that Appellant has not met his burden because the purported newly-discovered facts do not affect his case. Appellant has not averred that he was informed the expert testimony from his trial was reviewed by the FBI or the DOJ. To the contrary, the FBI neither conducted the relevant analysis in Appellant’s case, nor did an FBI analyst testify at trial. Surma was employed by the Pennsylvania State Police, and Appellant has not pointed to any evidence that supports the conclusion that Surma received training from the FBI.
      In his discovery motion, Appellant did not state that he ever contacted Surma or the Pennsylvania State Police to ask whether he was trained by the FBI. Additionally, Appellant's principal brief does not contain any argument pertaining to his motion for discovery. Appellant’s reply brief makes a reference to his discovery motion in the conclusion section, but does not raise any substantive argument. See Appellant’s Reply Brief at 5.
