Ohio Rev. Code Ann. § 1545.39

On receipt of notice of the filing of a petition with the county board of elections or an application for hearing or a notice of hearing from the probate court, the board of park commissioners shall cease all acquisition of land and the development of existing land unless valid options or contracts for which funds have been committed have been previously signed. No activity shall be resumed until the board of elections or the court determines, respectively, that the petition or application is invalid and the issue will not be voted on or heard, or the issue fails election, or the court finds against dissolution, whichever is earlier.
