Michigan Compiled Laws, Chapter 450. Corporations § 450.4409

Sec. 409. (1) Except as otherwise provided in an operating agreement, a transaction in which a manager or agent of a limited liability company is determined to have an interest shall not, because of the interest, be enjoined, be set aside, or give rise to an award of damages or other sanctions, in a proceeding by a member or by or in the right of the company, if the manager or agent interested in the transaction establishes any of the following:

(2) Except as otherwise provided in the articles of organization or an operating agreement, a transaction is authorized, approved, or ratified for purposes of subsection (1)(b) if it receives the affirmative vote of a majority of the managers that have no interest in the transaction. The presence of, or a vote cast by, a manager with an interest in the transaction does not affect the validity of an action taken under subsection (1)(b).

(3) Except as otherwise provided in the articles of organization or an operating agreement, a transaction is authorized, approved, or ratified for purposes of subsection (1)(c) if it receives a majority of votes cast by the members entitled to vote that do not have an interest in the transaction.

(4) Satisfying the requirements of subsection (1) does not preclude other claims relating to a transaction in which a manager or agent is determined to have an interest. Those claims shall be evaluated under principles of law applicable to a transaction in which a similarly situated person does not have an interest.
