Mich. Comp. Laws § 450.2441: Voting generally.

Sec. 441.

(1) Each outstanding share or member is entitled to 1 vote on each matter submitted to a vote, unless otherwise provided under section 303 or 304. A person may cast a vote at a meeting of the shareholders or members either orally or in writing, unless otherwise provided in the bylaws.

(2) If an action, other than the election of directors, is submitted for a vote of the shareholders or members, the action is approved or authorized if it receives the affirmative vote of a majority of the votes cast by the holders of shares or members entitled to vote on the action, unless a higher vote is required in the articles of incorporation or a higher or lower vote is required under another section of this act. Unless otherwise provided by the articles of incorporation, abstaining from a vote or submitting a ballot marked "abstain" with respect to an action is not a vote cast on that action. Except as otherwise provided in the articles of incorporation, directors are elected by a plurality of the votes cast at an election.
