N.D. Cent. Code § 10-15-11

The initial bylaws of a cooperative may be adopted by the temporary board. Thereafter, bylaws may be adopted and amended only by the members, unless the members adopt a bylaw that permits the board to make and amend specified bylaws. Any bylaw adopted or amended by the board shall be reported at the next regular member meeting. Any such bylaw shall be at any time subject to amendment or repeal by the members. Unless the bylaws provide otherwise, any bylaw may be adopted, amended, or repealed by a majority of the members present at a meeting, provided that the members voting must be sufficient in number to constitute a quorum as provided in this chapter or the bylaws.
