Mich. Comp. Laws § 450.1441

Sec. 441. (1) Each outstanding share is entitled to 1 vote on each matter submitted to a vote of the shareholders, unless otherwise provided in the articles of incorporation. A vote may be cast either orally or in writing, unless otherwise provided in the bylaws. (2) Other than the election of directors, if an action is to be taken by vote of the shareholders, it shall be authorized by a majority of the votes cast by the holders of shares entitled to vote on the action, unless a greater vote is required in the articles of incorporation or another section of this act. Unless otherwise provided in 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. Unless otherwise provided in the articles, directors shall be elected by a plurality of the votes cast at an election.
