(a) Each member has one vote except that bylaws may authorize voting according to actual, estimated or potential patronage, or a combination of these plans of voting. Shares of stock may not be given voting power except in the specific instances authorized by this chapter.

(b) Members may not vote by proxy. However, a member that is a corporation, association or partnership may designate a representative to cast its vote. In the absence of written notice that a person has been designated to represent a member which is other than a natural person, the member may be represented by any of its principal officers.

(c) If the bylaws of a cooperative provide for the formation of districts and the election of delegates at district meetings to represent their districts in member meetings, this representation is not considered voting by proxy. The delegates shall cast the votes to which members represented by them are entitled on those matters not covered by mail ballots submitted to all members.

(d) If the bylaws so provide, the board may have submitted by mail ballot any question to be voted on at a member meeting, including the election of directors. In this event the secretary shall mail to each member, along with the notice of the meeting, the ballot on each question and a voting envelope. The ballot shall be cast in a sealed envelope authenticated by the member's signature. A vote cast by mail shall be counted as if the member were present and voting in person.

(e) The bylaws may set forth provisions, not inconsistent with this chapter, relating to the methods and procedures for voting.
