Reduction of rates effective upon filing

With respect to any filing which, if approved, would result in a reduction of rates, the commissioner shall immediately order the proposed rates to be effective. If upon the commissioner's review of the filing or as a result of a public hearing it appears that the proposed rates should be further reduced, the commissioner may order the insurer or rating organization to show cause within thirty (30) days why such rates should not be further reduced in accordance with the order.
