Mont. Code § 33-11-121
The commissioner is authorized to use any powers established under this title to enforce the laws of this state so long as those powers are not specifically preempted by the federal Liability Risk Retention Act of 1986 ( 15 U.S.C. 3901, et seq.). The commissioner's powers include but are not limited to the commissioner'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 commissioner may rely on the procedural law and regulations of the state. The injunctive authority of the commissioner in regard to risk retention groups is restricted by the requirement that any injunction be issued by a court of competent jurisdiction.
