Lozman v. Riviera Beach

Background

Fane Lozman was a resident who lived on a floating home in the city marina. He opposed the city's plan to seize waterfront homes for private development and sued under Florida open-meetings laws. In a closed-door council meeting a member suggested using city resources to “intimidate” him, and the record shows others agreed. Months later during a public-comment session Lozman spoke about arrests of other officials, refused an order to stop, and a councilmember told an officer to “carry him out.” He was handcuffed and removed; the state later dismissed charges after finding probable cause. Lozman sued the city under federal law, alleging the arrest was retaliation for his speech; a jury found for the city.

Reasoning

The Court took a narrow issue: whether the existence of probable cause always defeats a First Amendment retaliatory-arrest claim against a city. The Court assumed probable cause existed but said this case differs because Lozman alleges the city itself adopted an official policy to retaliate. When a plaintiff shows an official municipal policy motivated by retaliation, the Mt. Healthy but‑for causation test applies instead of an automatic probable‑cause bar. The Court vacated the appeals court judgment and remanded for further fact-finding under that standard.

Real world impact

This ruling means people who claim a city adopted an official policy to punish their protected speech can pursue damages even if an arrest had probable cause. The decision is narrow and applies where the alleged retaliation was a city policy and is supported by objective evidence. On remand the appeals court must decide whether a reasonable jury could find the city formed and enforced a retaliatory policy in this case.

Dissents or concurrances

Justice Thomas dissented, arguing the Court should have held that plaintiffs must prove lack of probable cause to bring any retaliatory-arrest claim and would have required absence of probable cause in all such cases.
