Ohio Rev. Code Ann. § 745.11

When an ordinance granting an indeterminate permit contains no provisions whatever relative to appeal from or arbitration concerning the orders of the municipal corporation, the utility may appeal to the public utilities commission from any order of the municipal corporation which is in violation of law or of the permit, or from any unreasonable order concerning matters upon which the parties have not agreed in the permit itself. Such appeal shall be by petition filed within thirty days from the issuance of the order. The filing of any such appeal shall not suspend the operation of the order appealed from unless the public utility gives an undertaking payable to the municipal corporation in such amount and containing such conditions as are fixed by the commission.
