California Code, Government Code - GOV § 11371

(a) There is within the Office of Administrative Hearings a Medical Quality Hearing Panel, consisting of no fewer than five full-time administrative law judges. The administrative law judges shall have medical training as recommended by the Division of Medical Quality of the Medical Board of California and approved by the Director of the Office of Administrative Hearings.

(b) The director shall determine the qualifications of panel members, supervise their training, and coordinate the publication of a reporter of decisions pursuant to this section. The panel shall include only those persons specifically qualified and shall at no time constitute more than 25 percent of the total number of administrative law judges within the Office of Administrative Hearings. If the members of the panel do not have a full workload, they may be assigned work by the Director of the Office of Administrative Hearings. When the medically related case workload exceeds the capacity of the members of the panel, additional judges shall be requested to be added to the panels as appropriate. When this workload overflow occurs on a temporary basis, the Director of the Office of Administrative Hearings shall supply judges from the Office of Administrative Hearings to adjudicate the cases.

(c) The administrative law judges of the panel shall have panels of experts available. The panels of experts shall be appointed by the Director of the Office of Administrative Hearings, with the advice of the Medical Board of California. These panels of experts may be called as witnesses by the administrative law judges of the panel to testify on the record about any matter relevant to a proceeding and subject to cross-examination by all parties, and Section 11430.30 does not apply in a proceeding under this section. The administrative law judge may award reasonable expert witness fees to any person or persons serving on a panel of experts, which shall be paid from the Contingent Fund of the Medical Board of California upon appropriation by the Legislature.
