Ohio. R. Superi. Ct. 36.011
The individual assignment system is defined by the rule as a system whereby, upon the filing or transfer of a civil case, or upon arraignment in a criminal case, the case is immediately assigned to a judge of the court. The rule sets forth three purposes of the individual assignment system. All multi-judge divisions of the court of common pleas and all multi-judge municipal and county courts, except as provided in Sup.R. 36.012 through 36.015, are required to adopt the individual assignment system. Courts or divisions are permitted to deviate from the individual assignment system only if the modifications satisfy the three stated purposes of the system and are adopted by local rule of court pursuant to Sup.R. 5. Permissible modifications include the assignment and consideration of cases involving the same criminal defendant, parties, family members, or subject-matter.
The distinguishing feature of the individual assignment system is that it places responsibility upon one judge for the disposition of cases. Once a case is assigned to a judge under this system, all matters pertaining to the case are to be submitted to that judge for determination. An exception is made where that judge is unavailable. In that instance, the administrative judge may act in the assigned judge's absence.
Under Sup.R. 36.011, the administrative judge is responsible for the assignment of cases to the individual judges of the court. Assignment may be made by the administrative judge personally or by court personnel at the administrative judge's direction. All assignments of cases to individual judges must be made by lot.
The purpose of the random assignment, by lot, of cases is to avoid judge-shopping on the part of counsel and to distribute the cases equitably among the judges.
