Ohio Rev. Code § 4903.18
In case the supreme court stays or suspends any order or decision of the public utilities commission lowering any rate, joint rate, fare, toll, rental, charge, or classification, the commission, upon the execution and approval of the suspending bond required by section 4903.16 of the Revised Code, may require the public utility or railroad affected, under penalty of the immediate enforcement of the order or decision of the commission, pending review, to keep such accounts, verified by oath, as are, in the judgment of the commission, sufficient to show the amounts being charged or received by such public utility or railroad in excess of the charges allowed by the order or decision of the commission, together with the names and addresses of the corporations or persons to whom overcharges will be refundable in case the charges made by the public utility or railroad pending review are not sustained by the supreme court.
