What is the current standard for disclosure of confidential police files?

We begin with the well-settled standards for disclosure of confidential personnel records pursuant to Pitchess, which established that "a criminal defendant could 'compel discovery' of certain relevant information in the personnel files of police officers by making 'general allegations which establish some cause for discovery' of that information and by showing how it would support a defense to the charge against him." (Warrick v. Superior Court (2005) 35 Cal.4th 1011, 1018-1019 (Warrick); Pen. Code, 832.7, 832.8; Evid. Code, 1043-1045.)
