Wisconsin Statutes Insurance (Ch. 600 to 655) § 626.22. Disapproval of rates

(1) Order in event of violation. If the commissioner finds after a hearing that a filing already in effect under s. 626.13 fails to meet the requirements of the law, the commissioner shall order that its use be discontinued for any policy issued or renewed after a date specified in the order.

(2) Timing of order. The commissioner shall issue an order under s. 626.13 within 30 days after the filing and issue an order under sub. (1) within 30 days after the close of the hearing. In either case the commissioner may extend the period for a reasonable time by written order prior to the expiration of the time limit.

(3) Interim rates. Whenever an insurer has no legally effective rates as a result of an order by the commissioner under s. 626.13 or sub. (1), the commissioner shall on request specify interim rates for the insurer and may order that a specified portion of the premiums be placed in an escrow account approved by the commissioner. When new rates become legally effective, the commissioner shall order the escrowed funds or any overcharge in the interim rates to be distributed appropriately, except that refunds that are trifling shall not be required.
