Olivier v. City of Brandon: A Unanimous Decision On The Newly Defined Scope of §1983 and Collateral Attacks.

Introduction:
On March 20, 2026, Justice Kagan delivered the Court’s unanimous opinion in Olivier v. City of Brandon, which held that a prior conviction does not bar a petitioner from filing a Section 1983 suit if solely seeking prospective relief. In the context of Olivier’s case, the prospective — or future-focused — relief that the Court examines is an injunction that prohibits the future enforcement of an ordinance that is allegedly unconstitutional. Originating from the Civil Rights Act of 1871, Section 1983 (42 U.S.C. §1983) is a federal statute enabling individuals to sue state and local officials in federal court for civil rights violations and bring suits that seek damages or injunctions when officials violate constitutional or federal rights.

Kagan’s decision refines the holding established by the Court’s 1994 decision in Heck v. Humphrey, which has historically been invoked to prevent collateral attacks on the basis of Section 1983; these are essentially challenges brought by plaintiffs with criminal records who seek to file a new suit to circumvent the traditional routes of judicial review, habeas corpus or appellate proceedings, of their previous convictions. In the present decision, Justice Kagan clarifies this holding, asserting that the Heck standard has no bearing on plaintiffs who seek to purely enjoin the future enforcement of a law they argue to be unconstitutional and who do not seek to undo or obtain damages from their past conviction.

Case Question:
The case rests on a narrow question about the restriction and implementation of Heck v. Humphrey (1994): Does the standard established in Heck on the utilization of Section 1983 to prevent collateral attacks of a prior conviction extend to a suit that seeks relief that is wholly prospective?

Case Background & Procedural History:
A staunch Evangelical street preacher in Brandon, Mississippi, Gabriel Olivier maintained that the sharing of his religious beliefs in public is a core expression of his faith and, as such, is protected by the First Amendment. In 2021, Mr. Olivier was arrested for violating a City of Brandon ordinance, which required individuals engaged in “protests or demonstrations” near a local amphitheater during a scheduled event to remain within a specifically designated protest area. He pleaded no contest to the arrest, paid his $300 fine, and served his one year of sentenced probation. However, Mr. Olivier wanted to return to the amphitheater without fear of additional arrest and as such filed suit under 42 U.S.C. §1983, seeking a declarative judgement that the city’s ordinance violated the First Amendment and a concurrent injunction to prevent its future enforcement. Crucially, the plaintiff sought no damages or expungement of his prior conviction.

Both the District Court of Southern Mississippi and the US Court of Appeals For The Fifth Circuit held that Olivier’s suit was barred under the Heck Standard, as “judgment in favor of the plaintiff would necessarily imply the invalidity of his conviction.” The petitioner filed for a rehearing en banc, a request for the entire roster of judges in the circuit to hear the case, which was denied; however, eight — nearly half — of the Fifth Circuit’s judges dissented against the denial. The Supreme Court granted certiorari to resolve Olivier’s case.

The Arguments:
Anchoring its defense in Heck’s language, which maintained that when a section 1983 suit resulting in “judgment in favor of the plaintiff would necessarily imply the invalidity of his conviction,” The City of Brandon asserted the complaint must be dismissed. The city further contended that allowing the suit to continue would “intrude on the habeas statute’s domain” and “could lead to ‘parallel litigation’ and ‘conflicting’ judgments about the same conduct, with the §1983 suit suggesting that the plaintiff should be released even as criminal or habeas proceedings found the opposite.”

Contrastingly, Olivier argues the rule established in Heck “is subject to two limitations, either of which enables his suit to proceed.” Olivier first argues that “Heck does not apply (regardless of the relief sought) when the person suing was never in custody for his conviction,” meaning there was effectively no avenue of federal habeas proceedings for the plaintiff to pursue. Secondly, Olivier asserts that the holding does not “preclude a suit seeking wholly prospective relief, rather than relief relating to the prior conviction.” The Court resolved the case on the basis of Olivier’s second grounds alone, reasoning, “We need not address the former reason today because we agree with Olivier (and the Fifth Circuit’s dissenting judges) on the latter.”

Interestingly, Justice Kagen’s decision was heavily rooted in the Court’s 1977 decision in Wooley v. Maynard, in which the Court allowed a Section 1983 suit, following the plaintiff’s conviction under the challenged statute, that sought purely prospective relief. Kagan drew from the opinion, citing that a suit “in no way designed to annul the results of a state trial” could appropriately utilize Section 1983. As the Justice further explains, denying this vehicle would trap “‘the plaintiff…between the Scylla of intentionally flouting state law and the Charybdis of forgoing what he believes to be constitutionally protected activity.’” The opinion juxtaposes Wooley and Olivier, presenting the cases as structurally identical: entirely future-focused and producing no conflicting judgment with their prior convictions and consequently resolves Olivier’s case similarly. Finally, the Court emphasized the city’s overreach in their reading of Heck, highlighting that under their logic, the Heck standard would bar even a third party with no prior convictions that sought to enjoin the city’s ordinance, as a victory would equally invalidate Olivier’s conviction.

Conclusion:
In an increasingly divided court, the gravity of a unanimous decision can’t be ignored. Justice Kagen’s decision in this case dismantles the Fifth Circuit's expansive interpretation of Heck and effectively restores the function of Section 1983 as an avenue for constitutional challenges. Denying the challenges of anyone with a prior conviction under the law they seek to contest created precisely the trap that Wooley was working to prevent in forcing plaintiffs to choose between risking prosecution and silencing themselves and their constitutional challenges. The Court’s unanimous ruling crucially remands the question of whether the City of Brandon’s designated protest area is unconstitutional under the First Amendment, and ensures that the case will finally be heard; and for states utilizing prior convictions as a means to insulate their ordinances, that door is now closed.
