Modern Mootness Doctrine: General Criteria of Mootness

The Judicial Power shall extend to all Cases, in Law and Equity, arising under this Constitution, the Laws of the United States, and Treaties made, or which shall be made, under their Authority;—to all Cases affecting Ambassadors, other public Ministers and Consuls;—to all Cases of admiralty and maritime Jurisdiction; to Controversies to which the United States shall be a Party;—to Controversies between two or more States; between a State and Citizens of another State; between Citizens of different States,—between Citizens of the same State claiming Lands under Grants of different States, and between a State, or the Citizens thereof, and foreign States, Citizens or Subjects.

Under current law, “a case is moot when the issues presented are no longer 'live' or the parties lack a cognizable interest in the outcome.” 1 Footnote

Ctr. , 568 U.S. 597, 609 (2013) ( “It is a basic principle of Article III that a justiciable case or controversy must remain extant at all stages of review, not merely at the time the complaint is filed.” ) (quoting Juvenile Male , 564 U.S. at 936 ); Lewis v. Cont'l Bank Corp., 494 U.S. 472, 477–78 (1990) ( “To sustain our jurisdiction . . . it is not enough that a dispute was very much alive when suit was filed, or when review was obtained in the Court of Appeals.” ); Honig v. Doe, 484 U.S. 305, 317 (1988) ( “That the dispute between parties was very much alive when suit was filed . . . cannot substitute for the actual case or controversy that an exercise of this Court's jurisdiction requires.” ); Burke v. Barnes, 479 U.S. 361, 363 (1987) ( “Article III of the Constitution requires that there be a live case or controversy at the time that a federal court decides the case; it is not enough that there may have been a live case or controversy when the case was decided by the court whose judgment we are reviewing.” ). Thus, “[i]f an intervening circumstance deprives the plaintiff of a 'personal stake in the outcome of the lawsuit[]' at any point during litigation, the action can no longer proceed and must be dismissed as moot.” 3 Footnote
Campbell-Ewald Co. v. Gomez , 577 U.S. 153, 161 (2016) (quoting Genesis Healthcare Corp. v. Symczyk , 569 U.S. 66, 72 (2013) ). See also Calderon v. Moore, 518 U.S. 149, 150 (1996) (per curiam) ( “[M]ootness can arise at any stage of litigation.” ). “A case becomes moot only when it is impossible for a court to grant any effectual relief whatever to the prevailing party.” 4 Footnote
Knox v. Serv. Emps. Int'l Union, Local 1000 , 567 U.S. 298, 307 (2012) (quoting City of Erie , 529 U.S. at 287 ) (internal quotation marks omitted). See also, e.g., Mission Prod. Holdings, Inc. v. Tempnology, LLC , 139 S. Ct. 1652, 1660 (2019) (same); Campbell-Ewald , 577 U.S. at 161 (same); Decker , 568 U.S. at 609 (same); Chafin , 568 U.S. at 172 (same). When (1) “it can be said with assurance that there is no reasonable expectation that the alleged violation will recur;” and (2) “interim relief or events have completely and irrevocably eradicated the effects of the alleged violation,” then “the case is moot because neither party has a legally cognizable interest in the final determination of the underlying questions of fact and law.” 5 Footnote
Cty. of Los Angeles , 440 U.S. at 631 . See also, e.g., City of Erie , 529 U.S. at 287 (holding that a case becomes moot “when the challenged conduct ceases such that 'there is no reasonable expectation that the wrong will be repeated'” ) (quoting United States v. W.T. Grant Co., 345 U.S. 629, 633 (1953) ).

Significantly, however, a case does not necessarily become moot simply because intervening events make it impossible for a federal court to issue the exact form of relief that the plaintiff requests.6 Footnote
See Chafin , 568 U.S. at 177 ( “Such relief would of course not be fully satisfactory, but with respect to the case as a whole, even the availability of a partial remedy is sufficient to prevent a case from being moot.” ) (quoting Calderon , 518 U.S. at 150 ) (brackets and internal quotation marks omitted); Church of Scientology of Cal. v. United States, 506 U.S. 9, 12–13 (1992) ( “While a court may not be able to return the parties to the status quo ante . . . a court can fashion some form of meaningful relief in circumstances such as these . . . The availability of this possible remedy is sufficient to prevent this case from being moot.” ). As long as the court retains the ability to “fashion some form of meaningful relief, “then that” is sufficient to prevent th[e] case from being moot.” 7 Footnote
Church of Scientology , 506 U.S. at 12–13 . See also, e.g., Chafin , 568 U.S. at 177 ( “[E]ven the availability of a partial remedy is sufficient to prevent a case from being moot.” ) (quoting Calderon , 518 U.S. at 150 ) (brackets and internal quotation marks omitted). To illustrate, “[i]f there is any chance of money changing hands” as a result of the lawsuit, then the “suit remains live.” 8 Footnote
Mission Prod. Holdings , 139 S. Ct. at 1660 . Similarly, even if it is uncertain that the relief granted by the court will ultimately have any meaningful practical impact on the plaintiff, that does not itself render the case moot.9 Footnote
See Chafin , 568 U.S. at 175 ( “Enforcement of the order may be uncertain if Ms. Chafin chooses to defy it, but such uncertainty does not typically render cases moot. Courts often adjudicate disputes where the practical impact of any decision is not assured.” ).

The Court's 1974 opinion in DeFunis v. Odegaard illustrates how the aforementioned legal principles apply in practice.13 Footnote
416 U.S. 312 (1974) (per curiam) . The petitioner in DeFunis applied for admission at a public law school.14 Footnote
Id. at 314 . After the school rejected his application, the petitioner filed suit, “contending that the procedures and criteria employed by the Law School Admissions Committee invidiously discriminated against him on account of his race.” 15 Footnote
Id. See also infra Amdt14.S1.4.1.3.1.3.1.1 Appropriate Level of Scrutiny: Early Doctrine and Amdt14.S1.4.1.3.1.3.1.2 Appropriate Level of Scrutiny: Current Doctrine (discussing constitutional challenges to educational admissions practices that allegedly discriminate on the basis of race). The trial court agreed and ordered the law school to admit the petitioner.16 Footnote
Id. at 314–15 . The petitioner accordingly started taking classes at the law school while the case was on appeal.17 Footnote
Id. at 315 . By the time the case reached the Supreme Court, the petitioner had almost completed his law degree,18 Footnote
See id. such that the petitioner stood to “receive his diploma regardless of any decision th[e] Court might reach on the merits of [h]is case.” 19 Footnote
Id. at 317 . Because the petitioner would “complete his law school studies at the end of the term . . . regardless of any decision th[e] Court might reach on the merits,” the Court concluded that the case was moot.20 Footnote
Id. at 319–20 .

The Supreme Court has noted, however, “the decision whether to vacate” a moot case pursuant to Munsingwear “turns on 'the conditions and circumstances of the particular case.'” 36 Footnote
Azar , 138 S. Ct. at 1792 (quoting United States v. Hamburg-Amerikanische Packetfahrt-Actien Gesellschaft, 239 U.S. 466, 478 (1916) ). To that end, the Supreme Court has crafted several exceptions to the Munsingwear rule.37 Footnote
See, e.g., Camreta , 563 U.S. at 712 (explaining that, although the Munsingwear rule provides the “established” practice for resolving a civil case that “becomes moot pending appeal,” the Munsingwear doctrine is “not exceptionless” ). For one, the Supreme Court has specified that “vacatur is in order” under Munsingwear only when mootness occurs through “happenstance” —that is, “circumstances not attributable to the parties” —or “the 'unilateral action of the party who prevailed in the lower court.'” 38 Footnote
Arizonans for Official English , 520 U.S. at 71–72 (quoting U.S. Bancorp , 513 U.S. at 23 ). See also Azar , 138 S. Ct. at 1792 ( “One clear example where vacatur is in order is when mootness occurs through the unilateral action of the party who prevailed in the lower court.” ) (brackets and internal citations quotation marks omitted); Karcher v. May, 484 U.S. 72, 83 (1987) ( “Th[e] controversy did not become moot due to circumstances unattributable to any of the parties. The controversy ended when the losing party . . . declined to pursue its appeal. Accordingly, the Munsingwear procedure is inapplicable to this case.” ). Thus, if a case becomes moot as a result of the parties' mutual agreement to settle the case, the Court has held that federal courts should generally not vacate the judgment.39 Footnote
U.S. Bancorp , 513 U.S. at 29 . See also, e.g., Alvarez v. Smith , 558 U.S. 87, 94–97 (2009) (analyzing the interplay between Munsingwear and U.S. Bancorp ). The Court has justified this exception by explaining that “where mootness results from settlement . . . the losing party has voluntarily forfeited his legal remedy by the ordinary processes of appeal or certiorari, thereby surrendering his claim to the . . . remedy of vacatur.” 40 Footnote
U.S. Bancorp , 513 U.S. at 25 . Such cases are therefore “not unreviewable, but simply unreviewed” as a result of the losing party's “own choice.” 41 Footnote
Id. Likewise, the Court has ruled that it is inappropriate to “clear[] the path for future relitigation of the issues between the parties” 42 Footnote
See Munsingwear , 340 U.S. at 40 . when the plaintiff renders the case moot by voluntarily agreeing to permanently withdraw its claims against the defendant.43 Footnote
See Webster v. Reprod. Health Servs., 492 U.S. 490, 513 (1989) ; Deakins v. Monaghan, 484 U.S. 193, 199–200 (1988) . In such instances, rather than wiping the slate clean in the manner contemplated by Munsingwear , the Court has ordered that the case be dismissed with prejudice to refiling so that “it cannot be resumed in this or any subsequent action.” 44 Footnote
Deakins , 484 U.S. at 200 n.4 . See also Webster , 492 U.S. at 513 ( “Because this dispute was rendered moot in part by appellees' willingness permanently to withdraw their equitable claims from their federal action, a dismissal with prejudice is indicated.” ) (quoting Deakins , 484 U.S. at 200 ) (brackets omitted). Dismissing the case with prejudice thereby “prevent[s] the regeneration of the controversy” if the plaintiff later changes its mind and attempts to relitigate the dismissed claims in federal court.45 Footnote
Deakins , 484 U.S. at 200 .

Nor does the Court follow its usual practice of vacating the judgment with directions to dismiss when a case has become moot due to an intervening change in the governing law.46 Footnote
E.g., Lewis v. Cont'l Bank Corp., 494 U.S. 472, 482 (1990) ( “Our ordinary practice in disposing of a case that has become moot on appeal is to vacate the judgment with directions to dismiss. However, in instances where the mootness is attributable to a change in the legal framework governing the case, and where the plaintiff may have some residual claim under the new framework that was understandably not asserted previously, our practice is to vacate the judgment and remand for further proceedings in which the parties may, if necessary, amend their pleadings or develop the record more fully.” ) (internal citations omitted). Instead, the Court ordinarily “remand[s] for further proceedings in which the parties may, if necessary, amend their pleadings or develop the record more fully” to respond to the intervening change in law.47 Footnote
Id. See also U.S. Dep’t of Treasury, Bureau of Alcohol, Tobacco & Firearms v. Galioto, 477 U.S. 556, 559–60 (1986) (remanding case for further proceedings following amendment of statutory provision at issue); Crowell v. Mader, 444 U.S. 505, 505–06 (1980) ( “Appellees may still wish to attack the newly enacted legislation . . . [W]e direct that the judgment of the District Court be vacated without prejudice to such further proceedings in the District Court as may be appropriate.” ). For instance, in Diffenderfer v. Central Baptist Church of Miami, Florida, Inc. , the plaintiff challenged a Florida statute as unconstitutional.48 Footnote
404 U.S. 412, 412–14 (1972) (per curiam). While the litigation was pending, however, the Florida legislature repealed the challenged statute and enacted a new statute in its place.49 Footnote
Id. at 414 . “[R]ather than remanding the case to the District Court for dismissal” in the manner contemplated by Munsingwear , the Supreme Court “remand[ed] the case to the District Court with leave to the appellants to amend their pleadings.” 50 Footnote
Id. at 415 . Resolving the case in this way thereby afforded the appellants an opportunity “to demonstrate that the repealed statute retain[ed] some continuing force or to attack the newly enacted legislation.” 51 Footnote
Id.

Finally, “[t]he Court's treatment of cases that become moot on review from the lower federal courts” differs from its treatment of moot cases arising from state courts.52 Footnote
ASARCO Inc. v. Kadish, 490 U.S. 605, 621 n.1 (1989) . The Court's “regular practice in the latter situation has been to dismiss the case and leave the judgment of the state court undisturbed,” rather than to vacate the judgment in the manner contemplated by Munsingwear .53 Footnote
Id. (citing Kan. Gas & Elec. Co. v. State Corp. Comm'n of Kan. , 481 U.S. 1044 (1987) ; Times-Picayune Publ'g Corp. v. Schulingkamp , 420 U.S. 985 (1975) ). According to the Court, allowing state court judgments in moot cases to stand “evinces a proper recognition that in the absence of any live case or controversy, [the Court] lack[s] jurisdiction and thus also the power to disturb the state court's judgment.” 54 Footnote
Id.
