Ohio Rev. Code § 3937.35
Upon receipt of a notice of cancellation given pursuant to section 3937.33 of the Revised Code at any time prior to the effective date of cancellation of an automobile insurance policy, the insured may apply in writing to the superintendent of insurance for review of such cancellation. If the superintendent finds that there is cause to believe that such cancellation is based on erroneous information, or is contrary to law or the terms of the policy, the superintendent shall determine whether such cancellation is effective and shall give written notice of such finding to the insured and the insurer.
If the superintendent finds that such cancellation is in accordance with law and the terms of the policy, the superintendent shall issue a written finding approving such cancellation in such case.
If, upon review, the superintendent finds that such cancellation is contrary to law or the terms of the policy, the superintendent shall issue a written finding disapproving the cancellation and stating in what particulars the same is improper. In such case, the policy continues in force as provided in section 3937.33 of the Revised Code if the insured tenders to the insurer within ten days any premium refund made by the insurer.
