(a) The presiding officer shall determine a claim of privilege in any proceeding in the same manner as a court determines such a claim under Article 2 (commencing with Section 400) of Chapter 4 of Division 3.
(b) No person may be held in contempt for failure to disclose information claimed to be privileged unless he has failed to comply with an order of a court that he disclose such information. This subdivision does not apply to any governmental agency that has constitutional contempt power, nor does it apply to hearings and investigations of the Industrial Accident Commission, nor does it impliedly repeal Chapter 4 (commencing with Section 9400) of Part 1 of Division 2 of Title 2 of the Government Code. If no other statutory procedure is applicable, the procedure prescribed by Section 1991 of the Code of Civil Procedure shall be followed in seeking an order of a court that the person disclose the information claimed to be privileged.
