CA Gov't Code Section 11350.3

Any interested person may obtain a judicial declaration as to the validity of a regulation or order of repeal which the office has disapproved pursuant to Section 11349.3, or 11349.6, or of a regulation that has been ordered repealed pursuant to Section 11349.7 by bringing an action for declaratory relief in the superior court in accordance with the Code of Civil Procedure. The court may declare the regulation valid if it determines that the regulation meets the standards set forth in Section 11349.1 and that the agency has complied with this chapter. If the court so determines, it may order the office to immediately file the regulation with the Secretary of State.
