    Before: CABRANES, RAGGI, and CHIN, Circuit Judges.
   JOSÉ A. CABRANES, Circuit Judge:

Plaintiff Keepers, Inc. (“Keepers”) and defendant City of Milford, Connecticut (“Milford” or “the City”).appeal and cross-appeal, respectively, from partial summary judgment awards to each party by the United States District Court for the District of Connecticut (Alvin W. Thompson, Judge). This case presents two questions related to Chapter 2.3 Milford’s municipal code, which regulates “adult-oriented establishments.” The first is whether the District Court improperly considered the affidavit of Milford Chief of Police Keith Mello in granting partial summary judgment for the City. Keepers argues that the District Court should have struck the affidavit because it contradicted testimony given by Milford’s former city attorney in a deposition taken pursuant to Rule 30(b)(6) of the Federal Rules of Civil Procedure. We conclude that the District Court did not “abuse its discretion” in considering the affidavit, and we accordingly AFFIRM the District Court’s partial summary judgment award to the City.

The second question is whether the City’s requirement that sexually oriented businesses publicly post the names of their operators, officers, and significant owners violates the First Amendment. Keepers does not appeal a judgment by the District Court upholding that requirement with respect to individuals who operate, manage, or control such businesses, but Milford appeals the award of partial summary judgment in favor of Keepers holding the requirement unconstitutional with respect to passive owners and officers. The District Court should not have reached the merits of that issue, nor does this Court do so, because Keepers’ First Amendment challenge does not present a justiciable case or controversy under Article III of the U.S. Constitution. Accordingly, we VACATE the District Court’s partial judgment for Keepers insofar as it reached the merits of the public-posting requirement, and we .REMAND the cause to the District Court with direction to dismiss that claim for lack of subject-matter jurisdiction.

I. BACKGROUND

A. Milford’s Regulation of “Adult-Oriented Establishments”

Since 1996, Milford has regulated sexually oriented businesses (“SOBs” ) through its Ordinance Regulating Adults Oriented Establishments, which forms

Chapter 2.3 of its municipal code. In 2003, Milford amended Chapter 2.3 to add several new restrictions on SOBs, including regulations for live performances involving nudity, new licensing requirements for operators of SOBs, and periodic inspections. Most relevant here, the amended ordinance required an SOB to obtain an “adult-oriented establishment” license— which had to state the names of everyone who applied for it — and to post it “in a conspicuous place at or near the entrance ... so that it [could] be easily read at any time.”

Keepers fell within the scope of the 2003 ordinance. Keepers had been owned since 2001 by Joseph Regensberger, who initially operated the business as a restaurant and bar called Sidepockets. In 2002, however, Regensberger decided to convert Si-depockets into a “cabaret-style nightclub” featuring clothed and “seminude” female “dance entertainment.” He accordingly obtained from the City the necessary adult-entertainment license pursuant to Chapter 2.3.

In December 2003, shortly after Milford amended Chapter 2.3, Keepers filed suit in the District Court, challenging the ordinance’s constitutionality. The City agreed not to enforce the ordinance while the litigation was pending.

In 2007, Milford repealed and replaced the ordinance. Many of the provisions in the 2007 ordinance were similar to those they replaced, although .some requirements, such as those governing “adult arcades” — booths for viewing sexually explicit films — were stricter. Most relevant here, the 2007 ordinance introduced a more demanding public-posting requirement. Like the 2003 ordinance, the 2007 ordinance required an SOB to post its “adult-oriented establishment” license conspicuously near its entrance. But the 2007 ordinance expanded the list of individuals whose names had to appear on a license application — and, by extension, on the publicly posted license itself. Under the 2003 ordinance, the license had to include only the names of “operators” and “any other persons directly involved in the management or control of the adult-oriented establishment.” But the 2007 ordinance broadened that list to include “each person with an influential interest” in the SOB or in “a legal entity that controls” it. The 2007 ordinance defined “influential interest” to include “[a]ny of the following”:

(1)the actual power to operate the sexually oriented business or control the operation, management or policies of the sexually oriented business or legal entity which operates the sexually oriented business,
(2) ownership of a financial interest of thirty percent (30%) or more of a business or of any class of voting securities of a business, or
(3) holding an office (e.g., president, vice president,: secretary, treasurer, managing member, managing director, etc.) in a legal entity which operates the sexually oriented business.

In short, the 2007 ordinance required SOBs to publicly post the names of operators, managers, officers, and anyone owning at least thirty percent of the business.

Soon after Milford passed the 2007 ordinance, and while the earlier suit was still pending, Keepers brought a second lawsuit in the District Court, this time challenging the new law. Around the same time, Keepers changed owners. Regensberger had encountered several setbacks, including a brief suspension of his liquor license in 2003 as a result of alleged misbehavior by dancers at Keepers, and the loss of his liquor license in 2007 due to prostitution at another establishment he owned. In 2008, he sold Keepers to his bartender, Angela Silano, whom the record indicates to be the company’s president and sole owner.

In October 2008, the District Court consolidated Keepers’ first and second lawsuits, and both parties subsequently moved for summary judgment. In its motion, Keepers challenged the 2008 and 2007 ordinances on a number of constitutional grounds, and it also asserted that the ordinances violated the zoning requirements of Conn. Gen.Stat. § 8-2. Most relevant for this appeal, Keepers argued that the public-posting requirements of the 2003 and 2007 ordinances violated Keepers’ “owners’, employees’ and entertainers’ [First Amendment] right to anonymity while engaging in expressive activities.” Specifically, Keepers urged the District Court to apply so-called intermediate scrutiny and strike down the public-posting requirements because they did not further a substantial governmental interest.

In response, Milford argued that it had “a substantial interest in regulating those who control and operate sexually oriented businesses.” Specifically, Milford contended that the public-posting requirement allows “City officials and law enforcement agents to readily identify those who are responsible for the operation of a sexually oriented business for purposes of routine inspections and criminal investigations.”

On March 30, 2013, the District Court granted nearly all of Milford’s motion for summary judgment and denied nearly all of Keepers’ motion. Applying intermediate scrutiny, the Court agreed that Milford had a “substantial interest” in readily knowing who was responsible for operating an SOB, and that there was a “substantial relation between the City’s interest” and the requirement that SOBs display the names of their operators. The Court accordingly upheld the 2003 ordinance’s posting requirement.

The Court went on to find, however, that the 2007 ordinance’s posting requirement was “unconstitutionally broad.” Posting the names of owners and officers not involved in the actual operation of an SOB, the Court reasoned, lacked “a substantial relationship” to the City’s asserted interest Accordingly, the Court invalidated the 2007 ordinance insofar as it “require[d] the posting of the names of individuals who do not manage, operate or control the sexually oriented business.”

B. The Mello Affidavit

Keepers’ complaint alleged that various provisions of Chapter 2.3 were unconstitutionally vague. During discovery, Keepers sought to substantiate that allegation by developing evidence that City officials interpreted Chapter 2.3 in a manner inconsistent with its plain meaning or in a manner that gave inadequate notice of the conduct proscribed.

On December 5, 2008, Keepers served a notice of deposition on the City pursuant to Rule 30(b)(6) of the Federal Rules of Civil Procedure. Rule 30(b)(6) permits a party to depose an organization, including a governmental entity, by sending it a notice of deposition “describing] with reasonable particularity the matters for examination.” After receiving such notice, the organization must designate someone familiar with the matters described in the notice to testify on its behalf. If the organizational deponent fails to comply by “mak[ing] available such number of persons as will be able to give complete, knowledgeable and binding answers on its behalf,” a court may impose sanctions under Rule 87 of the Federal Rules of Civil Procedure, “including the preclusion of evidence.”

Keepers’ Rule 30(b)(6) notice of deposition listed thirty-one matters related to the drafting, passage, and enforcement of Chapter 2.3. Most relevant here, the notice identified as a matter for deposition “[t]he definition and interpretation of any provisions of Chapter 2.3 which are not specifically defined in that ordinance.” Neither Keepers’ complaint nor its notice of deposition identified which provisions of Chapter 2.3 Keepers believed to be vague, and its notice did not specifically identify which terms and provisions it planned to address during the deposition.

The City responded to Keepers’ notice of deposition by designating its former municipal attorney, Marilyn Lipton, who gave deposition testimony for Milford on January 8, 2009. At the start of the deposition, Milford’s attorney stated that, while Lipton had authority pursuant to Rule 30(b)(6) to testify on Milford’s behalf, she was “not authorized to contradict the ordinance text.”

During her deposition, Lipton was unable to answer various questions regarding the potential application and interpretation of Chapter 2.3. She was unable, for instance, to explain whether an “assistant manager” would fall within the 2007 ordinance’s definition of someone having an “influential interest” in an SOB; whether the City could revoke an SOB employee’s license for failing to stop another employee from “doing something wrong”; and whether mandated “buffer zones” between dancers and patrons would be measured from “front of body [to] front of body” or based on the distance between other body parts.

In its motion for summary judgment in August 2009, Keepers identified several provisions of Chapter 2.3 that it argued were unconstitutionally vague, relying on Lipton’s deposition for support. In its November 2009 response to Keepers’ motion, Milford filed an affidavit by Chief of Police Keith Mello (the “Mello Affidavit”), who was primarily responsible for administering the ordinance. The Mello Affidavit offered “additional guidelines regarding the interpretation and enforcement of Chapter 2.3,” with particular focus on those provisions that Keepers’ motion had identified as vague.

In December 2009, Keepers moved to strike the Mello Affidavit, arguing that it impermissibly contradicted Lipton’s deposition testimony. Keepers also moved for discovery sanctions. The District Court denied Keepers’ motions and relied on the Mello Affidavit in awarding summary judgment to the City on Keepers’ vagueness challenge. The District Court concluded that “[i]t would be unfair to ignore” the Mello Affidavit and to rely solely on the Lipton Deposition, “in which the plaintiffs succeeded in surprising a deponent not charged with enforcement of the ordinance with hypothetieals that served to ‘stump’ her.”

C. The Appeal

Both parties appealed the District Court’s partial grant and partial denial of summary judgment. Keepers appealed the denial of its motion to strike the Mello Affidavit and asked that the case be remanded for reconsideration of its vagueness challenge. Milford cross-appealed the District Court’s judgment that the 2007 ordinance’s public-posting requirement violates the First Amendment with respect to officers and shareholders not involved in the operation of an SOB.

In an Order entered on October 2, 2015, we identified nostra sponte two issues not addressed by the parties or the District Court: whether Keepers has “standing” to challenge the public-posting requirements; and, if Keepers does have standing, whether the public-posting requirements violate the First Amendment’s prohibition of “compelled speech.” We accordingly asked the parties to file supplemental letter briefs addressing these questions.

II. DISCUSSION

A. The District Court’s Consideration of the Mello Affidavit

We first address whether the District Court erred in considering the Mello Affidavit when awarding summary judgment to Milford with respect to Keepers’ vagueness challenge.

We review a district court’s evidentiary and discovery rulings for “abuse of discretion.” “A district court has abused its discretion if it based its ruling on an erroneous view of the law or on a clearly erroneous assessment of the evidence, or rendered a decision that cannot be located within the range of permissible decisions.”

On appeal, Keepers challenges the District Court’s decision to allow Milford to supplement the deposition testimony of its Rule 30(b)(6) witness with an affidavit from another witness. “Because the deponent’s answers constitute the official testimony of the governmental entity itself,” Keepers argues, “the government may not later contradict” the deponent’s testimony “with the affidavit of another official.” As a result, it asserts, the District Court should have refused to consider the Mello Affidavit.

Milford offers several counterarguments. First, it argues that even if a deponent’s factual conclusions bind an organizational deponent, its legal conclusions do not. Second, Milford asserts that Keepers’ notice of deposition failed to comply with Rule 30(b)(6)’s requirement that the deposing party “describe with reasonable particularity the matters for examination,” and that Milford was therefore entitled to supplement its deposition testimony on subjects about which it had received inadequate notice. Finally, Milford argues that even if the District Court erred in considering the affidavit, any error was harmless, because the Court would have reached the same conclusion in any event.

We affirm the District Court’s decision to consider the Mello Affidavit for two reasons. First, we agree with Milford that a Rule 30(b)(6) deponent may supplement or amend legal interpretations offered by its designated witness. Second, even if the District Court “abused its discretion” in considering the Mello Affidavit, any error was harmless.

1. The “Binding” Nature of Rule 30(b)(6) Testimony

Keepers misunderstands how testimony pursuant to Rule 30(b)(6) binds a party. Keepers rightly notes that an organization’s deposition testimony is “binding” in the sense that whatever its deponent says can be used against the organization. But Rule 30(b)(6) testimony is not “binding” in the sense that it precludes the deponent from correcting, explaining, or supplementing its statements. Nothing in the text of the Rule or in the Advisory Committee notes indicates that the Rule is meant to bind a corporate party irrevocably to whatever its designee happens to recollect during her testimony. Of course, a party whose testimony “evolves” risks its credibility, but that does not mean it has violated the Federal Rules of Civil Procedure.

Indeed, Keepers itself came to a similar conclusion earlier in this litigation. During the Lipton Deposition, Milford objected to questions requiring Lipton to give precise answers based on 2,000 pages of evidence. Its counsel emphasized that if Lipton answered a question with “I don’t know,” she should be taken to mean, “I don’t know without reviewing all 2,000 pages right now,” and that such an answer should “not preclude the city’s reliance on anything in the record at summary judgment.” The attorney for Keepers agreed: “I am sure that if there’s something that is in [the record] that is responsive to any arguments that we’re going to be making, you will pull it out in response to our motion for summary judgment.” Accordingly, the parties proceeded under the assumption that Lipton’s recollection did not limit what evidence Milford could present.

Although the parties’ exchange focused on Milford’s right to supply additional facts, a Rule 30(b)(6) deponent may also amend and expand its legal conclusions. Courts have held repeatedly that a party is “entitled to produce contrary evidence” that contradicts legal interpretations offered during a deposition. The statements to which Keepers seeks to bind Milford are primarily interpretations of law — whether or how Chapter 2.3 applies to various situations — rather than facts concerning the drafting or history of the ordinance. The rule that organizational deponents may supplement their Rule 30(b)(6) testimony thus applies with special force in the present ease.

Some deponents will, of course, try to abuse Rule 30(b)(6) by intentionally offering misleading or incomplete responses, then seeking to “correct” them by offering new evidence after discovery. Appropriate remedies are available for such situations. For instance, as Keepers points out, the “sham-affidavit rule” prevents a party from manufacturing an issue of fact “by submitting an affidavit in opposition to a summary judgment motion that, by omission or addition, contradicts the affiant’s previous deposition testimony.” But that rule has no relevance here. A subsequent witness does not “contradict” a Rule 30(b)(6) deponent when that witness offers information about which the deponent had disclaimed knowledge or expressed uncertainty. With one minor exception, the Mello Affidavit did not “contradict” Lipton’s earlier testimony but instead filled in its gaps.

Rule 37 also empowers district courts to correct abuses in the deposition process. If a deponent fails to satisfy Rule 30(b)(6) by refusing to designate a witness or producing an unprepared witness, the court may order sanctions, including the preclusion of evidence. But we cannot conclude that such sanctions would be appropriate here, much less that the District Court “abused its discretion” by failing to employ them against Milford.

Keepers identifies no authority that cuts against these settled principles. Indeed, the contrast between the instant case and Reilly v. Natwest Markets Group Inc., the principal case on which Keepers relies, is illuminating. In Reilly, a corporate defendant was served with a Rule 30(b)(6) notice asking it to produce representatives familiar with the work performed by the plaintiff, its former employee. In response, the defendant produced a single witness, “despite [the plaintiffs] complaints that [the witness] was not sufficiently knowledgeable,” in what was apparently an effort to frustrate the plaintiffs discovery. As a result, the district court refused to allow two other witnesses for the defendant — whom the defendant had declined to produce for its Rule 30(b)(6) deposition — to testify on the same subject at trial.

This case differs from Reilly in two important respects. First, unlike the corporate defendant in Reilly, Milford produced as its witness the person it considered to be most familiar with the subject matter at issue. Although Lipton’s testimony may have been inadequate, the District Court found that that inadequacy flowed not from the kind of willful obstruction apparent in Reilly but rather from Keepers’ decision to “surprisfe]” Lipton with “various hypothetical scenarios” not identified in the notice of deposition. Second, the defendant in Reilly wanted to frustrate discovery, but Milford had every incentive to be as forthcoming as possible in order to défeat Keepers’ claim of vagueness. Indeed, forcing Lipton to answer “I don’t know” was precisely what Keepers hoped to achieve.

As the District Court recognized, the process by which Milford ultimately answered Keepers’ questions was not “a route that is to be preferred.” Ideally— perhaps after receiving more particularized notice of what Keepers wanted to know — Lipton herself would have been prepared to offer more precise answers during her deposition. If Milford believed that Keepers’ Rule 30(b)(6) notice failed to describe the matters for deposition with adequate particularity, Milford could have objected prior to the deposition. Alternatively, Keepers might have requested an additional Rule 30(b)(6) deposition, perhaps of Mello. But the “management of discovery and trial” belongs “to the sound discretion of the district court.” We have no trouble concluding that the District Court did not “abuse” that discretion in admitting the Mello Affidavit.

2. Harmless Error

Even if the District Court erred by considering the Mello Affidavit, that error was harmless, because excluding the affidavit would not have affected the outcome of the case.

The District Court considered the Lipton Deposition and Mello Affidavit in connection with its evaluation of Keepers’ argument that certain provisions of Chapter 2.3 were unconstitutionally vague. An ordinance can be unconstitutionally vague “for either of two independent reasons”: (1) “if it fails to provide people of ordinary intelligence a reasonable opportunity to understand what conduct it prohibits,” or (2) if it “does not provide explicit standards for those who apply it.”

As the District Court noted, a court evaluating a challenge for vagueness must “begin[] with the text of the ordinance” itself. Based on its reading of Chapter 2.3 — without relying on the Lipton Deposition or the Mello Affidavit — the District Court concluded “that the ordinance here is clear on its face” and thus satisfied the first prong of the vagueness analysis.

In evaluating the second prong, the District Court again focused, as it should have, primarily on the ordinance’s plain meaning. The Court also considered whether Milford officials interpreted Chapter 2.3 in a manner “consistent with” its text. The Court concluded that the ordinance itself gave sufficiently clear guidance and that the officials charged with enforcing the ordinance had adopted an interpretation consistent with its text. Accordingly, the Court concluded that Chapter 2.3 also satisfied the second prong of the vagueness analysis.

The Court’s findings would not have changed had the Court excluded the Mello Affidavit. The Court concluded that the ordinance was clear on its face without relying on any extrinsic evidence at all. Had the Court relied solely on the Lipton Deposition in deciding whether the ordinance gave sufficient guidance to law enforcement, the most the Court could have concluded was that Milford lacked an “official position” on how to apply several provisions of Chapter 2.3 to various hypothetical situations. But that conclusion alone would not have supported a finding of vagueness. When the text of an ordinance is sufficiently clear to satisfy the Due Process Clause, a municipal official’s inability to supply precise answers regarding its hypothetical application is insufficient to render that ordinance unconstitutionally vague. The Mello Affidavit thus had no effect on the District Court’s ultimate conclusion. Accordingly, the judgment of the District Court in favor of Milford with respect to Keepers’ vagueness challenge is AFFIRMED.

B. The Public-Posting Requirement

We now turn to whether Milford’s public-posting requirements violate the First Amendment. Keepers does not appeal the District Court’s judgment insofar as it upheld the 2003 public-posting requirement and part of the 2007 requirement. Milford, however, urges us to reverse the District Court’s judgment insofar as it invalidated part of the 2007 ordinance. Milford argues that the District Court erred in assuming that mere ownership of an SOB is expressive conduct protected by the First .Amendment. It argues in the alternative that even if owning an SOB qualifies as expressive conduct, the posting requirement should nevertheless survive because it is narrowly tailored and advances an important governmental interest.

We need not — indeed, we cannot — resolve either issue today. Undertaking our constitutional duty to assure ourselves that this case is justiciable, we have determined that three distinct jurisdictional barriers preclude Keepers from challenging the public-posting requirements. We conclude that Keepers lacked both (1) prudential and (2) constitutional standing to challenge the public-posting requirements based on third parties’ rights to anonymous expression, and (3) even if Keepers had standing below based on its right against compelled speech, a justiciable controversy no longer exists at this stage of the litigation. Accordingly, we VACATE the judgment of the District Court with respect to the 2003 and 2007 public-posting requirements and REMAND with instructions to dismiss Keepers’ challenge to those requirements for lack of subject matter jurisdiction.

1. Whose First Amendment Rights Are at Stake?

Article III of the U.S. Constitution limits the jurisdiction of federal courts to “Cases” or “Controversies.” “One element of the case-or-controversy requirement is that plaintiffs must establish that they have standing to sue.” To establish constitutional standing, a plaintiff must demonstrate (1) that it has “suffered an injury in fact,” which is (2) “fairly traceable to the challenged action of the defendant,” and (3) “likely” to “be redressed by a favorable decision.” In addition to these core constitutional requirements, litigants must also satisfy “prudential standing,” which “embodies ‘judicially self-imposed limits on the exercise of federal jurisdiction.’ ” Prudential standing includes, inter alia, “the general prohibition on a litigant’s raising another person’s legal rights” and “the rule barring adjudication of generalized grievances more appropriately addressed in the representative branches [of government].” “The party invoking federal jurisdiction bears the burden of establishing” prudential and constitutional standing, but courts may raise the issue sua sponte, including for the first time on appeal.

One purpose of standing doctrine is to ensure that “the plaintiff at issue is the appropriate plaintiff to bring a claim.” It matters, in other words, whose rights a plaintiff asserts. The District Court assumed that the plaintiffs before it — a corporation and a limited liability company— were asserting “their First Amendment right to engage in speech anonymously.” But that would have been an odd claim indeed for a business like Keepers, which markets its services to “the consenting adult public.” Corporations sometimes seek to hide their identities, but not usually from their patrons.

A closer examination of Keepers’ filings reveals that the company has asserted not its own right to remain anonymous but that of its officers, shareholders, and other third parties. Before the District Court, for instance, Keepers argued that Milford’s public-posting requirements “impermissibly and severely infringe upon the owners’, employees’ and entertainers’ right to anonymity while engaging in expressive activities.” In its appellate brief, Keepers again stresses the right of “[o ]wners of adult businesses” “to fund sexually explicit expression” anonymously. Throughout its argument, Keepers refers either to an impersonal “right to anonymous free expression” or, more often, to the rights of “[pjassive [ojwners,” “shareholders,” and “officers.” Keepers’ brief even converts the District Court’s focus on Keepers ’ constitutional rights into a holding about the rights of “partial owners of sexually oriented businesses.” In short, Keepers has consistently asserted not its own right to anonymous expression — which would make little sense for a business that markets its services to the public — but the rights of third parties.

Therefore, to the extent that Keepers challenges the public-posting requirements based on a First Amendment right of anonymous expression, its challenge hinges on Keepers’ constitutional and prudential standing to assert the rights of its owners and officers. Corporations, like other organizations, sometimes have standing to assert the rights of third parties. But because a “corporation is a distinct legal entity” from its shareholders and officers, courts are not permitted to simply assume its standing to assert the rights of those third parties.

2. Prudential Standing

We begin by considering the “prudential standing rule” that “normally bars litigants from asserting the rights or legal interests of others in order to obtain relief from injury to themselves.”

Keepers argues that prudential standing concerns are irrelevant here because “[c]ourts have generally dispensed with the rule that a party [must] assert its own legal rights and not the rights of third parties when First Amendment free speech rights are at stake.” Keepers misunderstands the nature of that dispensation. Courts have relaxed prudential standing requirements to permit challenges based on First Amendment over-breadth. Keepers, however, has not advanced such a challenge here. Although Keepers’ supplemental brief repeatedly characterizes its claim as one of “over-breadth,” that word appears neither in its principal brief nor in the section of its summary judgment brief that addresses the public-posting requirement.

Keepers previously omitted mentioning overbreadth for a good reason: it has based its challenge on the “[q]uite different” basis of third-party (or jus tertii) standing. In an overbreadth challenge, a plaintiff “claims that although a statute did not violate his or her First Amendment rights, it would violate the First Amendment rights of hypothetical third parties if applied to them.” In contrast, a case based on third-party standing involves a plaintiffs claim “that a single application of a law both injures him and impinges upon the constitutional rights of third persons.” Keepers’ challenge is plainly of the latter variety.

“Typically, a plaintiff who asserts the claims of a third party can obtain standing by establishing (1) a close relationship to the injured party and (2) a barrier to the injured party’s ability to assert its own interests.” Even if we assume that Keepers and the relevant third parties have a sufficiently close relationship to satisfy the first prong of this test, Keepers has not shown, or even alleged, that its owners and officers would have any difficulty asserting their own interests. As a result, it has faded to offer any reason for us to lift the prudential bar against asserting the rights of others.

In reaching this conclusion, we emphasize the limited nature of our holding, which reflects the absence of any suggestion in the briefs or the record that Keepers’ owners or officers would face any difficulty in defending their own interests. We recognize that litigants seeking to protect their anonymity may have strong reasons for suing through a third-party organization rather than in their own names. But those reasons do not apply here. Keepers’ owners and officers have already identified themselves publicly during the course of this litigation, and we have seen no evidence that they would face “threats, harassment, or reprisals” from bringing a case in their own names. On the present record, then, Keepers has offered no reason to depart from the normal rule that a litigant must assert its own rights, not those of a third party.

3. Constitutional Standing

Even if we had reason to relax the prudential requirements of third-party standing, Keepers would still lack constitutional standing, because it has not satisfied Article Ill’s injury-in-fact requirement.

A litigant may assert the rights of others only if the litigant itself satisfies Article Ill’s requirements of injury-in-fact, causation, and redressability. The injury-in-fact requirement demands not only the existence of a legally cognizable injury, but also that the plaintiff itself be “among the injured.” In addition, “a plaintiff must demonstrate standing for each claim he seeks to press and for each form of relief that is sought.” In other words, Keepers’ undisputed standing to challenge Chapter 2.8 based on vagueness does not confer standing to challenge the public-posting requirements based on its officers’ and owners’ rights of anonymous expression.

In its motion for summary judgment, Keepers alleged several ways in which Milford’s ordinances have harmed its constitutional and economic interests. But neither in its appellate briefs nor before the District Court has Keepers explained how the alleged infringement of its officers’ and owners’ anonymity rights has caused it any harm. The closest it comes to doing so is through its suggestion that the public-posting requirements might “chill” Keepers’ expression. But “purely conjectural” assertions of a potential “chill” are insufficient, and Keepers offers no “objective evidence to substantiate [its] claim that the challenged regulation has deterred [it] from engaging in protected activity.”

Nor is Keepers able to claim constitutional standing based on its assertion that the public-posting requirement “injures Keepers directly by requiring it to participate in violating its owners’ right of privacy.” Even if Keepers’ statement were factually true, it would fail to give Keepers the kind of “particularized stake in the litigation” needed to satisfy Article III. Keepers asserts, in essence, that it is especially offended by Milford’s alleged violation of the First Amendment. But mere discomfort occasioned by an asserted constitutional violation, no matter how sharply felt, is insufficient to confer standing.

It is not difficult to imagine situations in which a burden on the First Amendment rights of a firm’s owners, officers, or employees might generate a legally cognizable injury to the firm itself. Standing, however, “cannot be inferred, but must affirmatively appear in the record,” and it is Keepers’ burden to demonstrate that the alleged infringement of third parties’ constitutional rights has injured Keepers itself. Keepers has not met that burden here.

4. Mootness on Appeal

In its supplemental brief, Keepers argues for the first time in this litigation that the public-posting requirement violates its First Amendment “right to be free from government-compelled expression.” According to Keepers, even if it lacked standing below to pursue a claim based on the right to anonymous expression, we can nonetheless uphold the District Court’s judgment on this alternative ground. Assuming arguendo that Keepers did not forfeit this argument by failing to present it below or in its principal brief, mootness precludes us from considering it.

“The case-or-controversy requirement subsists through all stages of federal judicial proceedings, trial and appellate.” A dispute that is live when suit is filed remains so only for as long as the parties continue to have a “concrete stake in the outcome.” There is “no case or controversy, and a suit becomes moot,” when the parties cease to have “a legally cognizable interest in the outcome” of the case.

When this litigation started, the alleged injury and the nature of the dispute would have been clear: Chapter 2.3 required Keepers to post names that it did not want to post. As a result, the requirement potentially implicated the right of Keepers’ owners and officers to express themselves anonymously, as well as Keepers’ own First Amendment right against compelled speech. At this stage of the litigation, however, that injury has disappeared.

The 2007 ordinance requires an SOB to post publicly the names of individuals who (1) have “actual power” to operate the business or control its “operation, management or policies”; (2) own at least thirty percent of the business; or (3) are officers of a legal entity that' operates the business. The District Court upheld this requirement except as it applies to individuals who “do not manage, operate or control the sexually oriented business.” Because Keepers does not appeal that decision, the only posting-related issue before this Court is the 2007 ordinance’s requirement that SOBs post the names of “[p]assive [o]wners” and officers. In other words, what is at stake in this appeal is whether Keepers must display the names of those individuals who fall within the scope of the 2007 ordinance’s public-posting requirement but “do not manage, operate or control” the business. We have seen no evidence that such persons exist. The record indicates that Keepers has no passive shareholders, but only a single owner, Angela Silano, who also serves as the company’s president and, as far as the record indicates, sole officer. Therefore, Keepers will have to display Silano’s name — regardless of the outcome of this appeal — under that part of the 2007 ordinance which the District Court upheld and which Keepers no longer challenges. That part of the 2007 public-posting requirement invalidated by the District Court has no effect on Silano’s anonymity, and Keepers has identified no other shareholders or officers whose anonymity might be implicated. As a result, we can identify no individual whose anonymity is potentially at stake in this appeal, nor will this appeal affect what information Keepers itself would be compelled to display.

In short, this appeal is moot, both with respect to Keepers’ third-party anonymity claim and its compelled-speech claim. Although Milford has a stake in defending the constitutionality of its ordinance, Keepers no longer has any concrete interest in the result of this appeal. As a result, this case now lacks “that concrete adverseness which sharpens the presentation of issues,” and which is necessary for a case to remain “fit for federal-court adjudication.”

5. Summary and Disposition of Keepers’ Challenge to the Public-Posting Requirements

We hold that Keepers lacks prudential and constitutional standing to challenge the public-posting requirements based on its owners’ and officers’ right of anonymous expression. We therefore VACATE the District Court’s judgment insofar as it reached the merits of this challenge and REMAND with direction to dismiss that claim. Insofar as Keepers urges us to uphold the judgment based on its own right against compelled speech, we find the appeal moot and DISMISS it accordingly.

III. CONCLUSION

To summarize, we hold as follows:

(1) The District Court did not “abuse its discretion” in considering the Mello Affidavit; and even if the District Court did err, its error was harmless, because it had no effect on the Court’s resolution of Keepers’ vagueness challenge.
(2) We do not reach the merits of Keepers’ First Amendment challenge to the public-posting requirements, because neither this Court nor the District Court has subject-matter jurisdiction to consider the issue.
a. Keepers challenged the public-posting requirement based on an asserted “First Amendment right to anonymous expression,” but the anonymity at stake is that of Keepers’ owners and officers, not that of Keepers itself.
b. The doctrine of “prudential standing” generally bars litigants from asserting the rights of third parties. Keepers has failed to show why we should permit it to assert the rights of its owners and officers in the present case.
c. Article III of the U.S. Constitution does not permit a plaintiff to sue unless it has suffered a legally cognizable injury. Keepers has failed to show that the public-posting requirement has injured the corporation itself — as opposed to its officers, owners, or related third parties.
d. Even if Keepers originally had standing to challenge the public-posting requirement in the District Court based on its asserted right against compelled speech, the case has become moot on appeal. Based on the record before us, Keepers’ president and sole owner will be required to list her name on Keepers’ posted license, regardless of who prevails before this Court. We'therefore lack jurisdiction to decide this appeal on the merits.

For the foregoing reasons, we AFFIRM the District Court’s March 30, 2013 judgment insofar as it denied Keepers’ motion to exclude the Mello Affidavit. We also VACATE that part of the March 30, 2013 judgment concerning plaintiffs First Amendment challenge to the public-posting requirements and REMAND to the District Court with direction to dismiss that claim for lack of subject-matter jurisdiction. Insofar as Keepers urges us to uphold the judgment based on its own claimed right against compelled speech, we DISMISS the appeal as moot.

The Milford ordinances usually refer to "adult-oriented establishments,” but they sometimes speak of "sexually oriented businesses” or "SOBs,” as do the parties and much of the relevant case law.

      . Id. It is not entirely clear whether the District Court held unconstitutional the 2007 ordinance’s requirement that the names of officers be posted. Its opinion suggests as much. See id. at 174 ("[P]osting the names of individuals based merely on their status as a 30% shareholder or an officer not involved in the management, operation or control of the sexually oriented business is not substantially related to the City’s interest in enforcing the ordinance.... Thus, the court concludes that § 2.3-5(c) of the 2007 ordinance is unconstitutional to the extent that it requires the posting of the names of individuals who do not manage, operate or control the sexually oriented business.” (emphasis supplied)). But in its subsequent Order of March 28, 2014, the Court declined to respond to Milford's argument about posting the names of officers "because the court did not find that requirement unconstitutional.” App. 151 n. 1. In this appeal, Milford seems to have adopted the interpretation provided by the March 28 Order— i.e., that the Court upheld its ordinance with respect to officers — while Keepers seems to have supposed the opposite. We assume that the District Court ruled as its opinion suggests, and that the Court struck down the 2007 public-posting requirement with respect to shareholders and officers "not involved in the management, operation or control of the sexually oriented business.” Keepers, 944 F.Supp.2d at 174. Nonetheless, our disposition of this appeal would not differ if the District Court had actually upheld the 2007 ordinance insofar as it applied to Keepers’ officers.

Fed.R.Civ.P. 37(a)(3)(B)(ii) permits a party seeking discovery to move for an order compelling designation if "a corporation or other entity fails to make a designation under Rule 30(b)(6).” If a corporation fails to comply with such an order, the court may impose the sanctions specified in Rule 37(b)(2)(A), which include
      (i) directing that the matters embraced in the order or other designated facts be taken as established for purposes of the action, as the prevailing party claims;
      (ii) prohibiting the disobedient party from supporting or opposing designated claims or defenses, or from introducing designated matters in evidence;
      (iii) striking pleadings in whole or in part;
      (iv) staying further proceedings until the order is obeyed;
      (v) dismissing the action or proceeding in whole or in part;
      (vi) rendering a default judgment against the disobedient party; or
      (vii)treating as contempt of court the failure to obey any order except an order to submit to a physical or mental examination.
      Rule 37(d)(l)(A)(i) provides for similar sanctions if "a person designated undér Rule 30(b)(6) ... fails, after being served with proper notice, to appear for that person’s deposition.” "Instead of or in addition to these sanctions, the court must require the party failing to act, the attorney advising that party, or both to pay the reasonable expenses, including attorney's fees, caused by the failure, unless the failure was substantially justified or other circumstances make an award of expenses unjust.” Fed.R.Civ.P. 37(d)(3).

Hobby Lobby Stores, Inc., — U.S. —, 134 S.Ct. 2751, 2768, 189 L.Ed.2d 675 (2014) ("An established body of law specifies the rights and obligations of the people (including shareholders, officers, and employees) who are associated with a corporation in one way or another. When rights, whether constitutional or statutory, are extended to corporations, the purpose is to protect the rights of these people.” (emphasis in original)); Doctor John's, Inc. v. City of Roy, 465 F.3d 1150, 1156 (10th Cir.2006) (finding that a sexually oriented business had standing to challenge an ordinance that directly harmed the business itself).

Patrickson, 538 U.S. 468, 474, 123 S.Ct. 1655, 155 L.Ed.2d 643 (2003) (“A basic tenet of American corporate law is that the corporation and its shareholders are distinct entities.”).

      Keepers cites Genusa v. City of Peoria, 619 F.2d 1203, 1216 (7th Cir.1980), for the proposition that a "coiporation ... ha[s] standing to challenge disclosure requirements that applied to officers, directors, and stockholders of a corporate licensing applicant.” Keepers Supp. Br. 3. Genusa, however, involved a suit brought by "owners of and employees in” a sexually oriented business, not by the business itself. See Genusa, 619 F.2d at 1208.

      . In contrast, Keepers attacked as over-broad the prohibition on minors’ entering SOBs, Keepers Br. Summ. J., Doc. 51, at 40-43; the requirement of a "buffer zone” between customers and "semi-nude” “employees,” id. at 51-52; and the "no-touch” provision, id. at 57.
      Although the District Court referred to the 2007 ordinance as "unconstitutionally broad,” context shows that the Court was referring to the absence of "a substantial relationship between [Milford’s asserted] governmental interest and the information required to be posted” — i.e., the ordinance’s failure to satisfy intermediate scrutiny — and not to the constitutional doctrine of over-breadth as relevant for standing purposes. See Keepers, 944 F.Supp.2d at 174. As noted above, the District Court never considered Keepers' standing to challenge the public-posting requirements; Keepers had not advanced an overbreadth argument; and the District Court invoked none of the typical overbreadth standards or doctrines in reaching its decision, see Milford Br. 36-37.

Nonetheless, we may affirm a district court "on any basis supported by the record, even one not relied on by the lower court,” and "[a]lthough it behooves appellees to raise all their defenses on appeal ... we are not aware of any case requiring them to do so.” Universal Church v. Geltzer, 463 F.3d 218, 229 (2d Cir.2006); cf. Int’l Trade Admin. v.

      We note that Silano would also have been required to post her name under the 2003 ordinance — if Milford had not repealed it — as an “officer or partner” of Keepers, since Sila-no is the only officer who appears in the record. See § 2.3-5 (2003).
     
      
      . In its supplemental brief, Keepers asserts for the first time that the current "president, secretary, and director of Keepers, Inc.” is not Silano but Julia Kish. Keepers Supp. Br. 4. As noted above, this assertion is irrelevant to our decision. Even if we were to relax our normal rule against considering new facts on appeal, see note 14, ante, Keepers has merely identified another third party who already lacks anonymity, not only because of this litigation, but because her name is already associated with Keepers on the website of the Connecticut Secretary of State. See Keepers Supp. Br. 4. Moreover, as "president, secretary, and director,” Kish would have to include her name on Keepers’ license as a person with "actual power to operate the sexually oriented business” or to control its operation. See §§ 2.3-2; 2.3-4(d) (2007). Keepers' supplemental brief did not identify any other shareholder or officer, besides Kish, whose anonymity might be implicated.
