CA Gov't Code Section 11455.20

(a)

The presiding officer or agency head may certify the facts that justify the contempt sanction against a person to the superior court in and for the county where the proceeding is conducted. The court shall thereupon issue an order directing the person to appear before the court at a specified time and place, and then and there to show cause why the person should not be punished for contempt. The order and a copy of the certified statement shall be served on the person. Upon service of the order and a copy of the certified statement, the court has jurisdiction of the matter.

(b)

The same proceedings shall be had, the same penalties may be imposed, and the person charged may purge the contempt in the same way, as in the case of a person who has committed a contempt in the trial of a civil action before a superior court.
