North Dakota Constitution Art. IV, § 12

A majority of the members elected to each house constitutes a quorum. A smaller number may adjourn from day to day and may compel attendance of absent members in a manner, and under a penalty, as may be provided by law.

Each house is the judge of the qualifications of its members, but election contests are subject to judicial review as provided by law. If two or more candidates for the same office receive an equal and highest number of votes, the secretary of state shall choose one of them by the toss of a coin.

Each house shall determine its rules of procedure, and may punish its members or other persons for contempt or disorderly behavior in its presence. With the concurrence of two-thirds of its elected members, either house may expel a member.
