Any insurer or rating organization aggrieved by any order or decision of the superintendent of insurance made without a hearing, may, within thirty days after notice of the order to the insurer or organization, make written request to the superintendent for a hearing thereon. The superintendent shall hear such party within twenty days after receipt of such request and shall not give less than ten days' written notice of the time and place of the hearing. Within fifteen days after such hearing the superintendent shall affirm, reverse, or modify his previous action, and specify his reasons therefor. Pending such hearing and decision the superintendent may suspend or postpone the effective date of his previous action.
Sections 3937.01 to 3937.17, inclusive, of the Revised Code do not require the observance at any hearing of formal rules of pleading or evidence.
Any order or decision of the superintendent, under such sections, is subject to review by the courts of this state and proceedings on review shall be de novo. No order or decision of the superintendent which is submitted for judicial review may become effective until after final action or decision by the court.
