Gabriel Olivier, a street preacher in Mississippi, was arrested in 2021 for violating a city ordinance that required protesters to stay in a designated area near a public amphitheater. He pleaded no contest, paid a fine, and served no prison time, though he was placed on probation. Olivier subsequently filed a federal lawsuit under 42 U.S.C. §1983, alleging that the ordinance violated his First Amendment rights by restricting where he could preach. He sought only prospective relief: a declaration that the ordinance was unconstitutional and an injunction preventing its future enforcement. He explicitly did not seek to overturn his prior conviction or obtain damages. The District Court and the Fifth Circuit agreed with the City of Brandon that the suit was barred by Heck v. Humphrey, reasoning that a judgment in Olivier's favor would necessarily imply the invalidity of his prior conviction. The Supreme Court granted certiorari to resolve whether Heck precludes such purely prospective challenges.
Justice Kagan, writing for a unanimous Court, distinguished the present case from Heck v. Humphrey by focusing on the nature of the relief sought. The Court explained that Heck was designed to prevent §1983 suits that function as collateral attacks on a conviction to secure release from custody or monetary damages, as such suits would intrude on the domain of habeas corpus and risk conflicting judgments. However, the Court noted that prior decisions, including Wooley v. Maynard, Edwards v. Balisok, and Wilkinson v. Dotson, established that §1983 remains available for claims seeking 'wholly prospective' relief. In this case, Olivier sought only to be free from future prosecutions, not to annul his past conviction. The Court reasoned that because Olivier's suit did not challenge the validity of his conviction for the purpose of release or damages, it did not fall within the core concerns of Heck. The Court addressed the City's argument that the 'necessarily imply' language in Heck should bar the suit, noting that general language must be read in context. The Court found that applying the City's logic would lead to untenable results, such as barring a citizen with a clean record from challenging the same ordinance. Therefore, the Court held that Olivier's suit, which looks forward to preventing future enforcement, is not barred by Heck and may proceed.
The decision allows individuals with prior convictions to challenge the constitutionality of statutes under §1983 if they seek only prospective injunctive relief to prevent future enforcement. This clarifies the scope of the Heck bar, ensuring that plaintiffs are not forced to choose between flouting the law or forgoing their constitutional rights. The case is remanded to the lower courts for further proceedings consistent with the opinion, allowing Olivier to pursue his First Amendment challenge.
