CA Gov't Code Section 11370.3

The director shall appoint and maintain a staff of full-time, and may appoint pro tempore part-time, administrative law judges qualified under Section 11502 which is sufficient to fill the needs of the various state agencies. The director shall also appoint any other technical and clerical personnel as may be required to perform the duties of the office. The director shall assign an administrative law judge for any proceeding arising under Chapter 5 (commencing with Section 11500) and, upon request from any agency, may assign an administrative law judge to conduct other administrative proceedings not arising under that chapter and shall assign hearing reporters as required. Any administrative law judge or other employee so assigned shall be deemed an employee of the office and not of the agency to which he or she is assigned. When not engaged in hearing cases, administrative law judges may be assigned by the director to perform other duties vested in or required of the office, including those provided for in Section 11370.5.
