California Code, Insurance Code - INS § 11626

If the commissioner, after hearing upon not less than ten (10) days' notice, finds that any insurer has failed to perform any of the duties required of it by this article or by the plan, other than those duties enumerated in Section 11625, he may issue an order to such insurer specifying in what manner and to what extent he finds the insurer to have so failed and requiring, within a reasonable time, not less than 10 days, compliance with such requirements. If within the period specified in the order the insurer fails to comply with such order, such insurer shall, in addition to any other penalty provided by law, forfeit to the State a penalty of five hundred dollars ($500) for each such failure. The commissioner may bring an action in his own name against the insurer to collect the said penalty.
