Lozman v. Riviera Beach

Fane Lozman was arrested at a Riviera Beach city council meeting after he spoke critically about alleged corruption among local officials. The criminal charges against him were eventually dropped. Lozman then filed a federal lawsuit under 42 U.S.C. § 1983, claiming the arrest was an act of retaliation for his protected speech in violation of the First Amendment. The district court and the U.S. Court of Appeals for the Eleventh Circuit ruled against him, holding that the existence of probable cause for the arrest defeated his retaliatory-arrest claim as a matter of law. The Supreme Court granted certiorari to resolve a circuit split on whether probable cause acts as an absolute bar to such claims.

In an 8-1 decision authored by Justice Anthony M. Kennedy, the Supreme Court held that the presence of probable cause does not automatically bar a First Amendment retaliatory-arrest claim. The Court ruled that a plaintiff may still pursue such a claim if they can demonstrate that the arrest was substantially motivated by retaliation against protected speech. The judgment of the Eleventh Circuit was vacated, and the case was remanded for further proceedings consistent with this opinion. Justice Clarence Thomas dissented.

Whether the existence of probable cause for an arrest categorically defeats a First Amendment retaliatory-arrest claim brought under 42 U.S.C. § 1983.

The ruling significantly strengthened First Amendment protections by ensuring that law enforcement cannot use the existence of probable cause as an absolute shield against claims of retaliatory arrest. It clarified that citizens retain the right to challenge arrests motivated by a desire to suppress speech, thereby reinforcing public participation at government meetings and accountability for local governments. The decision resolved a longstanding circuit split and shaped the landscape of civil rights litigation involving police retaliation.
