A court may adopt rules for the conduct of criminal proceedings before it, not in conflict with provisions of this Code or of other laws. When a court has more than one judge, its rules shall be adopted or amended by a majority of the judges thereof, sitting en banc.
The rules shall be entered on the minutes of the court, and a copy shall be furnished on request to any attorney licensed to practice law in this state.
