巴恩斯诉费利克斯案

On April 28, 2016, Harris County Deputy Roberto Felix Jr. pulled over Ashtian Barnes on the Sam Houston Tollway for suspected toll violations. During the stop, Felix ordered Barnes to exit the vehicle, but Barnes began to drive away. Felix jumped onto the car's doorsill and fired two shots, fatally wounding Barnes. Barnes's mother sued Felix under 42 U.S.C. § 1983, alleging violation of Barnes's Fourth Amendment right against excessive force. The District Court granted summary judgment to Felix applying the Fifth Circuit's "moment-of-threat" rule, and the Court of Appeals affirmed. The Supreme Court granted certiorari and issued its unanimous decision on May 15, 2025.

The Supreme Court unanimously vacated the Fifth Circuit's judgment and remanded the case for further proceedings. Justice Elena Kagan delivered the opinion for a unanimous Court, holding that the Fourth Amendment requires analyzing the "totality of the circumstances" with no time limit, including events leading up to the use of force. Justice Kavanaugh filed a concurring opinion joined by Justices Thomas, Alito, and Barrett. On remand, the Fifth Circuit affirmed that Officer Felix was entitled to qualified immunity.

The central dispute was whether the Fifth Circuit's "moment-of-threat" rule—which evaluates excessive force claims solely by examining whether the officer was in danger at the precise moment deadly force was used—is consistent with the Fourth Amendment's requirement that reasonableness be assessed under the "totality of the circumstances." The lower courts had confined their analysis to the two seconds Felix was on the moving car's doorsill, excluding all prior events. The Supreme Court addressed whether earlier facts and circumstances may bear on how a reasonable officer would have perceived and responded to the situation.

The decision unanimously rejected the Fifth Circuit's "moment-of-threat" doctrine, resolving a consequential circuit split. It clarified that courts evaluating excessive force claims must consider the full context of police-civilian encounters, not just split-second decisions. The ruling heightens the importance of comprehensive record-keeping and scenario-based training for law enforcement agencies, as prior interactions and situational developments can now be scrutinized in excessive force litigation.
