What is the test for discovery of confidential personnel records of a peace officer accused of misconduct against a defendant?

Under Pitchess, "on a showing of good cause, a criminal defendant is entitled to discovery of relevant documents or information in the confidential personnel records of a peace officer accused of misconduct against the defendant. [Citation.] . . . If the defendant establishes good cause, the court must review the requested records in camera to determine what information, if any, should be disclosed. [Citation.] Subject to certain statutory exceptions and limitations [citation], 'the trial court should then disclose to the defendant "such information [that is relevant to the subject matter involved in the pending litigation."' [Citations.]" (People v. Gaines (2009) 46 Cal.4th 172, 179.)
