Ohio Rev. Code § 707.13: Filing, docketing, and hearing of petition.

The court of common pleas shall hear the petition not less than twenty days from the filing thereof and at such hearing the court may hear evidence upon the matters averred in the petition. If the court finds no error in the proceedings before the board of county commissioners and that the board's decision was reasonable and lawful, the petition for such injunction shall be dismissed. Thereupon the clerk shall return such papers to the county recorder, with a certified transcript of the order of the court, and the recorder shall immediately make a record and file a copy of the record with the secretary of state as provided in section 707.09 of the Revised Code.
