The director is authorized to make use of any of the powers established under the Insurance Code to enforce the laws of this state so long as those powers are not specifically preempted by the federal Product Liability Risk Retention Act of 1981, as amended by the Risk Retention Amendments of 1986. This includes, but is not limited to, the director’s administrative authority to investigate, issue subpoenas, conduct depositions and hearings, issue orders and impose penalties. With regard to any investigation, administrative proceedings or litigation, the director may rely on the procedural law and rules of the state. The injunctive authority of the director in regard to risk retention groups is restricted by the requirement that any injunction be issued by a court of competent jurisdiction. [1987 c.774 § 106]
