Several state law enforcement agencies would like to inform prosecutors if officers have misconduct on their records, so prosecutors can seek and give to defendants any potential exculpatory evidence, as required by 'Brady v. Maryland.' But California's 'Pitchess' laws say officer personnel files can only be opened in response to court orders. This week's guests offered arguments Wednesday before the state high court on how to resolve this seeming puzzle. Geoffrey Sheldon (Liebert Cassidy Whitmore) argued on behalf of the information-sharing policy; Judy Posner (Benedon & Serlin) and Elizabeth Gibbons (The Gibbons Firm) represented a union of sheriff's deputies, and argued against it.
