Ohio Revised Code Title XXXIX. Insurance § 3935.07

Every member of, or subscriber to, a rating bureau shall adhere to the filings made on its behalf by the bureau, except that any insurer who is such a member or subscriber may make written application to the superintendent of insurance for permission to file a deviation from the class rates, schedules, rating plans, or rules respecting any kind of insurance or class of risk within a kind of insurance, or combination thereof. Such application shall specify the basis for the modification, and a copy of the application shall be sent simultaneously to the rating bureau. The superintendent shall set a time and place for a hearing at which the insurer and the rating bureau may be heard, and shall give them not less than ten days' written notice thereof. If the superintendent is advised by the rating bureau that it does not desire a hearing, he may, upon the consent of the applicant, waive the hearing. In considering the application for permission to file the deviation, the superintendent shall give consideration to the available statistics and the principles for rate making as provided in section 3935.03 of the Revised Code. The superintendent shall issue an order permitting the deviation for such insurer to be filed if he finds it is justified, and it shall thereupon become effective. He shall issue an order denying such application if he finds that the resulting premiums would be excessive, inadequate, or unfairly discriminatory. Each deviation permitted to be filed shall be effective until terminated with the approval of the superintendent or as may otherwise be permitted or required by law.
