Mont. Code § 35-16-311
At the organization meeting or any meeting of the stockholders or members of a corporation or district organized under the provisions of this chapter, each member and each unit of membership in acres, production, or other evidence of membership is entitled to vote in person or by proxy. Corporate action at a meeting must be determined by a majority of the membership and a majority of the acres, production, or units of membership, as may have been adopted. Any group of members of a subdivision or subdistrict of the corporation or district as may be defined and designated by the board of directors or the bylaws shall, at a subdivision or subdistrict meeting called for the purpose, elect a delegate or proxy to represent all of the membership in the subdivision or subdistrict at any organization meeting or meeting of the stockholders or members. If any subdivision or subdistrict fails to elect a delegate, any individual member may give a proxy. However, a person who is not a member of the corporation or district and a resident agricultural or horticultural freeholder in the state of Montana for at least 3 years immediately preceding the meeting is not entitled to act as proxy.
