617.0823 Waiver of notice.—Notice of a meeting of the board of directors need not be given to any director who signs a waiver of notice either before or after the meeting. Attendance of a director at a meeting constitutes a waiver of notice of such meeting and a waiver of any objection to the date of the meeting, the place of the meeting, the time of the meeting, or the manner in which it has been called or convened, except when a director states, at the beginning of the meeting or promptly upon arrival at the meeting, any objection to holding the meeting or the transaction of affairs because the meeting is not lawfully called or convened and, after such objection, the director does not vote for or consent to action taken at the meeting.
