California Code, Government Code - GOV § 66639

(a) Within 30 days after service of a copy of a cease and desist order issued by the executive director under Section 66637 or the commission under Section 66638, any aggrieved party may file with the superior court a petition for writ of mandate for review thereof pursuant to Section 1094.5 of the Code of Civil Procedure. Failure to file such an action shall not preclude a party from challenging the reasonableness and validity of an order of the executive director or the commission in any judicial proceedings brought to enforce such order or for other civil remedies.

(b) The evidence before the court in any proceeding to review an order of the commission described in subdivision (a) shall consist of the record before the commission, and in cases where it is claimed that the findings are not supported by the evidence, abuse of discretion is established only if the court determines that the findings are not supported by substantial evidence in the light of the whole record.
