A court may adopt rules for the conduct of judicial business before it, including those governing matters of practice and procedure which are not contrary to the rules provided by law. 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 may provide that the court may call a special session of court during vacation, and that any action, proceeding, or matter otherwise required by law to be tried or heard in open court during the regular session may be tried or heard during the special session.

The rules shall be entered on the minutes of the court. Rules adopted by an appellate court shall be published in the manner which the court considers most effective and practicable. Rules adopted by a district court shall be printed in pamphlet form, and a copy shall be furnished on request to any attorney licensed to practice law in this state.
