Mich. Comp. Laws § 450.1641

Sec. 641.

(2) Any of the following may adopt restated articles of incorporation for a corporation, as applicable: (a) Before the first meeting of the board, all of the incorporators, by complying with the provisions of sections 611(1)(a), 642, and 643(1). (b) If the restated articles of incorporation merely restate and integrate, but do not further amend the articles as amended, the restated articles of incorporation may be adopted by the board without a vote of the shareholders. (c) If the restated articles of incorporation restate, integrate, and also further amend the articles of incorporation, but the amendments include only amendments adopted under section 611(1)(b) or (2), the board may adopt the restated articles of incorporation without a vote of the shareholders. (d) If the restated articles of incorporation restate, integrate, and amend the articles of incorporation and subdivisions (a), (b), and (c) do not apply, the shareholders must adopt the restated articles of incorporation under section 611. (3) An amendment made to the articles of incorporation in connection with the restatement and integration of the articles of incorporation is subject to any other provision of this act, not inconsistent with this section, that would apply if a certificate of amendment were filed to effect that amendment.
