Ohio Revised Code Title XLI. Labor and Industry § 4121.26

If upon the trial of an action under section 4121.25 of the Revised Code it appears that all issues arising in the action have not theretofore been presented to the bureau of workers' compensation in the petition filed as provided in section 4121.23 of the Revised Code, or that the bureau has not theretofore had ample opportunity to hear and determine any of the issues raised in the action, or has for any reason not in fact heard and determined the issues raised, the court shall, before proceeding to render judgment, unless the parties to the action stipulate to the contrary, transmit to the bureau a full statement of the issues not adequately considered and shall stay further proceedings in the action for fifteen days from the date of transmission and may thereafter grant such further stay as is necessary.

Upon the receipt of the statement the bureau shall consider the issues not theretofore considered, and may alter, modify, amend, or rescind its order complained of in the action, and shall report its order thereon to the court within ten days from the receipt of the statement from the court for further hearing and consideration.

The court shall thereupon order such amendment or other proceeding as is necessary to raise the issues as changed by the modification of order as has been made by the bureau upon the hearing, if any modification has in fact been made, and shall thereupon proceed with the action in the manner provided by law for other civil actions.
