Mellen v. Winn

The Ninth Circuit reversed the district court's grant of summary judgment to defendant based on qualified immunity grounds in a 42 U.S.C. 1983 action alleging that defendant failed to disclose evidence that would have cast serious doubt on the star prosecution witness in plaintiff's trial. The panel held that the record demonstrated as a matter of law that defendant withheld material impeachment evidence under Brady v. Maryland and Giglio v. United States, and raised a genuine issue of material fact as to whether defendant acted with deliberate indifference or reckless disregard for plaintiff's due process rights. The panel also held that the law at the time of the 1997–98 investigation clearly established that police officers investigating a criminal case were required to disclose material, impeachment evidence to the defense. Finally, the panel held that the district court abused its discretion by striking the declaration of plaintiff's police practices expert. The panel remanded for further proceedings. View "Mellen v.
