(a) Except as provided in paragraph (b), the quorum for a members' meeting to transact business is:
(1) ten percent of the total number of members for a cooperative with 500 or less members; or
(2) 50 members for cooperatives with more than 500 members.
(b) The quorum provisions of paragraph (a) apply notwithstanding quorum requirements of the articles or the bylaws, except for:
(1) a larger quorum in articles filed by a cooperative after March 26, 1949; or
(2) a larger quorum provided by amending the articles or bylaws after May 1, 1959.
In determining a quorum at a meeting, on a question submitted to a vote by mail, members present in person or represented by mail vote shall be counted. The attendance of a sufficient number of members to constitute a quorum shall be established by a registration of the members of the cooperative present at the meeting. The registration shall be verified by the president and secretary of the cooperative and shall be reported in the minutes of the meeting.
An action by a cooperative is not valid or legal in the absence of a quorum at the meeting at which the action was taken.
