California Code, Welfare and Institutions Code - WIC § 5326.91

In any facility in which convulsive treatment is performed on a person whether admitted to the facility as an involuntary or voluntary patient, the facility will designate a qualified committee to review all such treatments and to verify the appropriateness and need for such treatment. The local mental health director shall establish a postaudit review committee for convulsive treatments administered anywhere other than in any facility as defined in Section 1250 of the Health and Safety Code in which psychiatric evaluation or treatment is offered. Records of these committees will be subject to availability in the same manner as are the records of other hospital utilization and audit committees and to other regulations. Persons serving on these review committees will enjoy the same immunities as other persons serving on utilization, peer review, and audit committees of health care facilities.
