Michigan Compiled Laws, Chapter 450. Corporations § 450.1511

Sec. 511. (1) The shareholders may remove 1 or more directors with or without cause unless the articles of incorporation provide that directors may be removed only for cause. The vote for removal shall be by a majority of shares entitled to vote at an election of directors except that the articles may require a higher vote for removal without cause. This section shall not invalidate any bylaw adopted before the effective date of the act which added this sentence insofar as the bylaw applies to removal without cause.

(2) In the case of a corporation having cumulative voting, if less than the entire board is to be removed, no 1 of the directors may be removed if the votes cast against his or her removal would be sufficient to elect him or her if then cumulatively voted at an election of the entire board of directors, or, if there are classes of directors, at an election of the class of directors of which he or she is a part.

(3) If holders of a class or series of stock or of bonds are entitled by the articles to elect 1 or more directors, this section applies, with respect to removal of a director so elected, to the vote of the holders of the outstanding shares of that class or series of stock or the holders of those bonds.
