California Code, Labor Code - LAB § 123.7

The appeals board may, by rule or regulation, establish procedures whereby attorneys who are either certified specialists in workers' compensation by the California State Bar, or are eligible for this certification, may be appointed by the presiding workers' compensation judge of each board office to serve as a pro tempore workers' compensation judge in a particular case, upon the stipulation of the employee or his or her representative, and the employer or the insurance carrier. Service in this capacity by an attorney shall be voluntary and without pay. It is the intent of the Legislature that the use of pro tempore workers' compensation judges pursuant to this section shall not result in a reduction of the number of permanent civil service employees or the number of authorized full-time equivalent positions.
