Is there any need for an independent review of the sealed records on the Pitchess proceedings?

Appellant contends, and respondent agrees, that we should conduct an independent review of the sealed records on the Pitchess proceedings to determine whether the trial court inquired about the completeness of the records produced for inspection, whether the court administered the oath to a custodian of records, and whether the trial court abused its discretion in ruling there was no discoverable information. (Pitchess v. Superior Court, supra, 11 Cal.3d 531.)
