If, prior to the filing of an action under Chapter 2731. of the Revised Code or during the pendency of the action, the judge exercises the judge’s contempt power in order to obtain the sum of money in dispute, the judge shall not order the imprisonment of any member of the board of county commissioners notwithstanding sections 2705.02 to 2705.06 of the Revised Code.
