Cal. VEH § 12209

If the recovery corporation denies the claim, the recovery corporation shall notify the applicant in writing of the denial, the legal and factual bases for the denial, and the applicant’s right to contest the denial in writing within 60 days or any longer period permitted by the recovery corporation. If the applicant does not contest the denial within 60 days or an additional period reasonably requested by the consumer, the decision shall be final. The recovery corporation shall act on the applicant’s objection within 30 days. If the claim is denied in whole or in part, the applicant may seek review in the superior court of any of the following counties in which the office of the Attorney General maintains an office: Sacramento, San Francisco, Los Angeles, or San Diego. Review shall be limited to the written record before the recovery corporation and any relevant evidence that could not have been previously presented to the recovery corporation despite the applicant’s reasonable diligence. The superior court shall affirm the decision of the recovery corporation if it is supported by substantial evidence.
