1Any party may, by motion, for good cause shown, request the judge to disqualify a mediator. The request must state with particularity the basis for disqualification. Any order disqualifying a mediator shall name a substitute mediator. Nothing in this rule shall preclude mediators from disqualifying themselves or refusing any assignment. A mediator disqualifying herself or himself, or refusing an assignment shall do so informally by electronic mail to the Deputy Chief Judge. Thereupon, the Deputy Chief Judge shall re-assign the case to another mediator.
