What are the requirements of the custodian of a law enforcement officer's personnel file for in camera review?

"When a trial court concludes a defendant's Pitchess motion shows good cause for discovery of relevant evidence contained in a law enforcement officer's personnel files, the custodian of the records is obligated to bring to the trial court all 'potentially relevant' documents to permit the trial court to examine them for itself. [Citation.] [An] officer's personnel record will commonly contain many documents that would, in the normal case, be irrelevant to a Pitchess motion, including those describing marital status and identifying family members, employment applications, letters of recommendation, promotion records, and health records. [Citation.] Documents clearly irrelevant to a defendant's Pitchess request need not be presented to the trial court for in camera review." (People v. Mooc (2001) 26 Cal.4th 1216, 1228-1229 (Mooc).)
