Cal. Gov. Code § 11523
Judicial review may be had by filing a petition for a writ of mandate in accordance with the provisions of the Code of Civil Procedure, subject, however, to the statutes relating to the particular agency. Except as otherwise provided in this section, the petition shall be filed within 30 days after the last day on which reconsideration can be ordered. The right to petition shall not be affected by the failure to seek reconsideration before the agency. On request of the petitioner for a record of the proceedings, the complete record of the proceedings, or the parts thereof as are designated by the petitioner in the request, shall be prepared by the Office of Administrative Hearings or the agency and shall be delivered to the petitioner, within 30 days after the request, which time shall be extended for good cause shown, upon the payment of the cost for the preparation of the transcript, the cost for preparation of other portions of the record and for certification thereof. The complete record includes the pleadings, all notices and orders issued by the agency, any proposed decision by an administrative law judge, the final decision, a transcript of all proceedings, the exhibits admitted or rejected, the written evidence and any other papers in the case. If the petitioner, within 10 days after the last day on which reconsideration can be ordered, requests the agency to prepare all or any part of the record, the time within which a petition may be filed shall be extended until 30 days after its delivery to him or her. The agency may file with the court the original of any document in the record in lieu of a copy thereof. If the petitioner prevails in overturning the administrative decision following judicial review, the agency shall reimburse the petitioner for all costs of transcript preparation, compilation of the record, and certification.
