Ohio Rev. Code § 3935.08
Any member of, or subscriber to, a rating bureau may appeal to the superintendent of insurance from the action of such rating bureau in approving or rejecting any proposed change in, or addition to, the filings of such rating bureau. The superintendent shall, after a hearing held upon not less than ten days' written notice to the appellant and to such rating bureau, issue an order approving the action of such rating organization or directing it to give further consideration to such proposal. If such appeal is from the action of the rating bureau in rejecting a proposed addition to its filings, the superintendent may, if he finds that such action was unreasonable, issue an order directing the rating organization to make an addition to its filings on behalf its members and subscribers, in a manner consistent with his findings and within a reasonable time after the issuance of such order.
