Mich. Comp. Laws § 450.1467

Sec. 467. (1) A trustee who votes shares subject to a voting trust incurs no responsibility as shareholder, trustee or otherwise, except for his malfeasance. (2) Where 2 or more persons are designated as voting trustees, and the right and method of voting shares in their names at a meeting of shareholders are not fixed by the agreement appointing the trustees, the right to vote and the manner of voting the shares at the meeting shall be determined by a majority of the trustees. If the trustees are equally divided as to how the shares shall be voted, the vote shall be divided equally among the trustees.
