C.R.S. § 7-56-304: Quorum.

(1) A quorum for conducting business at all meetings of the members shall be five percent of the total number of members or thirty members present in person at the meeting, whichever is less. Members present and voting in person or in any other manner authorized by the cooperative pursuant to section 7-56-305 (1) shall be counted toward the quorum with respect to that matter. Nothing shall prevent the articles or the bylaws of a cooperative from requiring a greater number of members or percentage thereof as a quorum.

(2) An action by a cooperative is not valid in the absence of a quorum at the meeting at which the action was taken, unless the action taken is subsequently ratified by the required number of members.
