Cal. Government Code § 1097.5

(a) If the time for judicial review of a final Commission order or decision issued pursuant to Section 1097.2 has lapsed, or if all means of judicial review of the order or decision have been exhausted, the Commission may apply to the clerk of the superior court for a judgment to collect the penalties imposed by the order or decision, or the order as modified in accordance with a decision on judicial review. (1) The application, which shall include a certified copy of the order or decision, or the order as modified in accordance with a decision on judicial review, and proof of service of the order or decision, constitutes a sufficient showing to warrant issuance of the judgment to collect the penalties. The clerk of the court shall enter the judgment immediately in conformity with the application. (2) An application made pursuant to this section shall be made to the clerk of the superior court in the county where the monetary penalties, fees, or civil penalties were imposed by the Commission. (3) A judgment entered in accordance with this section has the same force and effect as, and is subject to all the provisions of law relating to, a judgment in a civil action and may be enforced in the same manner as any other judgment of the court in which it is entered. (4) The Commission may bring an application pursuant to this section only within four years after the date on which the monetary penalty, fee, or civil penalty was imposed. (b) The remedy available under this section is in addition to those available under Section 1097.4 or any other law.
