(A) Authority of Commission. The commission has all the powers provided for under Const 1963, art 6, § 30, and further powers provided by Supreme Court rule. Proceedings before the commission or a master are governed by these rules. The commission may adopt and publish administrative rules for its internal operation and the administration of its proceedings that do not conflict with this subchapter and shall submit them to the Supreme Court for approval.
(B) Review as an Appellate Court. The commission may not function as an appellate court to review the decision of a court or to exercise superintending or administrative control of a court, but may examine decisions incident to a complaint of judicial misconduct, disability, or other circumstance that the commission may undertake to investigate under Const 1963, art 6, § 30, and MCR 9.207. An erroneous decision by a judge made in good faith and with due diligence is not judicial misconduct.
(C) Control of Commission Action. Proceedings under these rules are subject to the direct and exclusive superintending control of the Supreme Court. No other court has jurisdiction to restrict, control, or review the orders of the master or the commission.
(D) Errors and Irregularities. An investigation or proceeding under this subchapter may not be held invalid by reason of a nonprejudicial irregularity or for an error not resulting in a miscarriage of justice.
(E) Jurisdiction Over Visiting Judges. Notwithstanding MCR 9.116(B), the Attorney Grievance Commission may take action immediately with regard to a visiting judge who currently holds no other judicial office if the allegations pertain to professional or personal activities unrelated to the judge’s activities as a judge.
