Tennessee Code Title 3. Legislature § 3-18-112

(a) The commissioners within the delegation, including any alternate commissioners filling a vacancy, shall choose from among them a chair of the delegation, a person who must cast the state's vote on the convention floor, and a person to speak to the media on behalf of the delegation.  If the delegation so decides, the same person may exercise any or all such functions.  The delegation may designate a different commissioner to perform any function at any time.

(b) Each commissioner shall take care to avoid communicating the impression to a person outside of the delegation that the delegation is divided on a question on which the delegation has taken a formal position, including, but not limited to, whether to cast a vote for or against a proposal.

(c) Except for the commissioner designated to communicate with the media on behalf of the delegation, a commissioner shall not communicate with the media about convention business during the convention or during any temporary recess or temporary adjournment.

(d) A commissioner who violates subsection (b) or (c) may be suspended, recalled, or removed by the general assembly or the advisory committee.

(e) Subsections (b) and (c) must not be construed to prevent a commissioner from presenting the commissioner's opinions at the convention or debating a matter at the convention on which the commissioner's delegation has not formally taken a position.

(f) The quorum for decision by the delegation, including the designation of commissioners for particular duties or functions and the determination of how the state's vote will be cast, is a majority present and voting at the time the delegation is polled.  A decision must not be made and a vote must not be cast if less than a majority of the delegation votes in the poll.

(g) The rule of decision for the delegation, a quorum being present, is that a majority of commissioners must be present and voting at the time of polling.
