(a) Whenever the commissioner shall have reason to believe that any person engaged in the business of insurance is engaging in this state in any method of competition or in any act or practice in the conduct of the business that is not defined in Section 790.03, and that the method is unfair or that the act or practice is unfair or deceptive and that a proceeding by him or her in respect thereto would be in the interest of the public, he or she may issue and serve upon that person an order to show cause containing a statement of the methods, acts or practices alleged to be unfair or deceptive and a notice of hearing thereon to be held at a time and place fixed therein, which shall not be less than 30 days after the service thereof, for the purpose of determining whether the alleged methods, acts or practices or any of them should be declared to be unfair or deceptive within the meaning of this article. The order shall specify the reason why the method of competition is alleged to be unfair or the act or practice is alleged to be unfair or deceptive.
The hearings provided by this section shall be conducted in accordance with the Administrative Procedure Act (Chapter 5 (commencing with Section 11500) of Part 1 of Division 3 of Title 2 of the Government Code), except that the hearings may be conducted by an administrative law judge in the administrative law bureau when the proceedings involve a common question of law or fact with another proceeding arising under other Insurance Code sections that may be conducted by administrative law bureau administrative law judges. The commissioner and the appointed administrative law judge shall have all the powers granted under the Administrative Procedure Act. If the alleged methods, acts, or practices or any of them are found to be unfair or deceptive within the meaning of this article the commissioner shall issue and service upon that person his or her written report so declaring.
(b) If the report charges a violation of this article and if the method of competition, act or practice has not been discontinued, the commissioner may, through the Attorney General of this state, at any time after 30 days after the service of the report cause a petition to be filed in the superior court of this state within the county wherein the person resides or has his or her principal place of business, to enjoin and restrain the person from engaging in the method, act or practice. The court shall have jurisdiction of the proceeding and shall have power to make and enter appropriate orders in connection therewith and to issue any writs as are ancillary to its jurisdiction or are necessary in its judgment to prevent injury to the public pendente lite.
(c) A transcript of the proceedings before the commissioner, including all evidence taken and the report and findings shall be filed with the petition. If either party shall apply to the court for leave to adduce additional evidence and shall show, to the satisfaction of the court, that the additional evidence is material and there were reasonable grounds for the failure to adduce the evidence in the proceeding before the commissioner, the court may order the additional evidence to be taken before the commissioner and to be adduced upon the hearing in the manner and upon the terms and conditions as to the court may seem proper. The commissioner may modify his or her findings of fact or make new findings by reason of the additional evidence so taken, and shall file modified or new findings with the return of the additional evidence.
(d) If the court finds that the method of competition complained of is unfair or that the act or practice complained of is unfair or deceptive, that the proceeding by the commissioner with respect thereto is to the interest of the public and that the findings of the commissioner are supported by the weight of the evidence, it shall issue its order enjoining and restraining the continuance of the method of competition, act or practice.
