North Dakota Century Code Title 10. Corporations § 10-15-18. Quorum

A quorum at a member meeting shall be ten percent of the first one hundred members plus five percent of additional members, present in person or represented by delegates. Unless the bylaws fix a larger number of members to constitute a quorum, a quorum shall never be more than fifty members nor less than five members, or a majority of all members, whichever is smaller. Members represented by signed vote may be counted in computing a quorum only on those questions as to which the signed vote is taken. The provisions of this section shall not apply to an electric generation or transmission cooperative as provided in subsection 10 of section 10-13-03 and a quorum for such cooperative at a meeting of its membership shall be as provided in its bylaws.
