Tennessee Code Title 48. Corporations and Associations § 48-239-113

(1) Unless the articles or operating agreement provides otherwise, an action required or permitted to be taken at a board of governors meeting may be taken without a meeting. If all governors consent to taking such action without a meeting, the affirmative vote of the number of governors that would be necessary to authorize or take such action at a meeting is the act of the board of governors. The action must be evidenced by one (1) or more written consents describing the action taken, signed by each governor in one (1) or more counterparts, indicating the signing governor's vote or abstention on the action, and shall be included in the minutes or filed with the LLC's records reflecting the action taken.

(2) Notwithstanding subdivision (a)(1), the articles or operating agreement may provide for written governor action to be taken without all governors consenting to the waiver of actual meeting, but such consent must be of at least two thirds ( 2/3 ) of the governors.
