California Code, Welfare and Institutions Code - WIC § 5328.9

If at such time as a patient's hospital records are required by an employer to whom the patient has applied for employment, such records shall be forwarded to a qualified physician or psychiatrist representing the employer upon the request of the patient unless the physician or administrative officer responsible for the patient deems the release of such records contrary to the best interest of the patient.

If the physician or administrative officer responsible for a patient deems the release of such records contrary to the best interest of the patient, he shall notify the patient within five days.  In the event that the disclosure of the patient's records to the patient himself would not serve his best interests, the physician or administrative officer in question shall render formal notice of his decision to the superior court of the county in which the patient resides.
