33-16-113. Appeal from order or decision of commissioner. Any person, insurer, or rating organization aggrieved by any order or decision made by the commissioner under this chapter may appeal to the district court of the county where the aggrieved party may reside or has a principal place of business in this state or to the district court of Lewis and Clark County, Montana. The appeal must be taken within 30 days from the making and filing of the order or decision by filing in the office of the commissioner a notice of the appeal in writing. The commissioner shall, within 20 days after filing of the notice, make and return to the district court a full and complete certified transcript of the finding and order appealed from and of all parts relative to the finding and order on file in the commissioner's office, including the notice of appeal. Upon filing of the certified transcript, all matters involved in the appeal must be brought on for trial upon the merits at the next term of the court after the filing of the transcript unless otherwise ordered by the court. Upon the trial, the findings of fact on which the order is based must be prima facie evidence of the matters stated. During the pendency of the proceedings upon review, the order of the commissioner is suspended, but in the event of a final determination against any insurer, any overcharge by the insurer during review must be refunded to the persons entitled to the refund.
