In multi-judge circuits, unless a majority of the judges in a circuit elect to adopt a different system, all actions, civil and criminal, shall be assigned by the clerk of each superior court according to a plan approved by such judges to the end that each judge is allocated an equal number of cases. The clerk shall have no power or discretion in determining the judge to whom any case is assigned; the clerk’s duties are ministerial only in this respect and the clerk’s responsibility is to carry out the method of assignment established by the judges. The assignment system is designed to prevent any persons choosing the judge to whom an action is to be assigned; all persons are directed to refrain from attempting to affect such assignment in any way. If the order or the timing of filing is a factor in determining case assignment, neither the clerk nor any member of the clerk’s staff shall disclose to any person the judge to whom a case is or will be assigned until such time as the case is in fact filed and assigned.
