Whether the named plaintiffs had an Article III case or controversy supporting prospective injunctive relief against the city officials.
Holding
No. The individual plaintiffs did not show a real and immediate threat that they would again suffer injury attributable to the named officials' conduct.
Reasoning
Past exposure to unlawful police conduct, without a continuing present injury or a sufficiently immediate threat of repeated injury, does not itself establish standing to seek an injunction. The Court relied on O'Shea v. Littleton, which held that anticipated future exposure to unlawful official conduct cannot rest on speculation.
The asserted future injury was especially attenuated here. It depended on the possibility that an unidentified officer from a small minority of the force would later mistreat a plaintiff, based on that officer's perception of the department's disciplinary procedures. That chain of contingencies did not give the individual plaintiffs the necessary personal stake in an order restructuring those procedures.
Because the named plaintiffs lacked a live controversy with the officials, they ordinarily could not seek classwide relief. Although the case had proceeded to trial and the classes had been certified, the Court concluded that the lower courts' broader theory of § 1983 liability could not cure the absence of a sufficiently direct injury traceable to the defendants.
