Michigan Compiled Laws, Chapter 450. Corporations § 450.1521

Sec. 521. (1) Regular or special meetings of a board may be held either in or outside this state.

(2) A regular meeting may be held with or without notice as prescribed in the bylaws. A special meeting shall be held upon notice as prescribed in the bylaws. A director's attendance at or participation in a meeting waives any required notice to him or her of the meeting unless he or she at the beginning of the meeting, or upon his or her arrival, objects to the meeting or the transacting of business at the meeting and does not thereafter vote for or assent to any action taken at the meeting. Unless required by the bylaws, neither the business to be transacted at, nor the purpose of, a regular or special meeting need be specified in the notice or waiver of notice of the meeting.

(3) Unless otherwise restricted by the articles of incorporation or bylaws, a member of the board or of a committee designated by the board may participate in a meeting by means of conference telephone or other means of remote communication through which all persons participating in the meeting can communicate with the other participants. Participation in a meeting pursuant to this subsection constitutes presence in person at the meeting.
