A supreme court justice is subject to impeachment by the legislature for malfeasance or misfeasance in the performance of official duties. Impeachment shall originate in the senate and shall be approved by a two-thirds vote of its members. The motion for impeachment must list fully the basis for the proceeding. Trial on impeachment shall be conducted by the house of representatives. A supreme court justice designated by the court shall preside at the trial. Concurrence of two-thirds of the members of the house is required for a judgment of impeachment. The judgment may not extend beyond removal from office, but does not prevent proceedings in the courts on the same or related charges.
