Any person violating any of the provisions of Section 17531.7 or 17531.8 may be enjoined by any superior court of competent jurisdiction upon action for injunction, brought by the Attorney General or any district attorney in this state, and the superior court shall, after proof of violation, issue an injunction or other appropriate order restraining such conduct. This injunctive remedy shall not be construed to limit the district attorney of the county wherein the violation occurred from prosecuting criminal action for any violations of Section 17531.7 or 17531.8.
