(A) Judges elected under section 2301.03 of the Revised Code as judges of the court of common pleas, division of domestic relations, shall hear all conciliation cases. (B) In counties having more than one judge of the court of common pleas, but no division of domestic relations, the presiding judge or the judges of that court shall designate, in January of each year, one or more of their number to hear all conciliation cases. A conciliation judge may request that any case before him be assigned by the presiding judge for hearing or other proceedings by any other common pleas judge, whenever in the opinion of the conciliation judge the assignment is necessary to expedite any case. When any case is so assigned, the judge to whom it is assigned acts as a conciliation judge. (C) The presiding judge of the court of common pleas may appoint a judge of the court of common pleas to act as conciliation judge during any period when a conciliation judge is on vacation, is absent, or is for any reason unable to perform his duties.
