Los Angeles County, California v. Mendez

Issues: (1) Whether the U.S. Court of Appeals for the 9th Circuit disregarded the Supreme Court’s clear directives on remand and whether, in a 42 U.S.C. § 1983 action, a plaintiff’s injuries resulting from a police officer’s use of force may be proximately caused by the officer’s failure to secure a search warrant; (2) whether, in an action brought under 42 U.S.C. § 1983, conduct giving rise to an officer’s reasonable use of force is an intervening, superseding event which breaks the chain of causation for damages stemming from the officer’s failure to secure a warrant; and (3) whether a federal court of appeals may reverse a district court’s determination under Rule 52(a) of the Federal Rules of Civil Procedure that an officer did not breach his duty of care to use reasonable force in a negligence action without applying a clearly erroneous standard of review.
