Voting.  A majority of all the members constituting the county legislative body, and not simply a majority of the quorum, is required to take any action, including making appointments, filling vacancies, fixing salaries, appropriating money, and transacting any other business coming before the county legislative body in regular or special meetings.  T.C.A. §§ 5-5-108 and 5-5-109.  The majority vote requirement means a majority of the actual membership at the time and not a majority of the total authorized membership, so a vacancy would not be counted in determining the required majority.  Bailey v. Greer, 468 S.W.2d 327 (Tenn. Ct. App. 1971).

Questions often arise as to the effect of an abstention or “pass” vote.  If a member abstains from voting or “passes” for any reason other than a statutory conflict of interest, the vote has the practical effect of a “nay” vote.  It is not counted as one of the required “yea” votes necessary to meet the majority approval required for adoption, and yet it must be counted in determining the number necessary for a majority. Attorney General Opinion 86-17 (1/1/86).  If, however, a member abstains from voting because of a statutory conflict of interest, that member is not counted for purposes of determining the number necessary for a majority.  T.C.A. § 5-5-102(c)(3)(B).

While most business coming before the Commission requires a simple majority vote, some measures require a “supermajority” vote of two-thirds (2/3) of the members.  This is true for the approval of private acts, as well as for imposing some tax measures.  Where a supermajority is required, it will be stated in the enabling legislation (general law or private act).

The following chart illustrates the number of votes required for a majority of the county legislative body. 

For example, if your county commission has 19 members, 10 votes are needed to pass a resolution (unless there is a vacancy or a member abstains due to a T.C.A. § 12-4-101 conflict of interest, and announces that intention to the chairman of the legislative body). If 15 of the 19 members are present at the meeting, 10 votes are still needed. If a county legislative body has 15 members, 10 of whom are present for a meeting, all ten of those would have to vote in the affirmative in order to pass a measure requiring a two-thirds vote; eight of the ten present would constitute a majority.

Tie votes - If the County Commission is equally divided on any vote, then and only then a county mayor chair may, but is not required, to cast the deciding vote.  A member serving as chairman votes as a regular member and cannot vote a second time to break a tie. T.C.A. § 5-5-109.

Procedure - All business for action of the county legislative body must be presented to the chair who announces the business to the body and takes the vote which is recorded by the county clerk.  The body cannot act on any business which is not presented to the chair unless the body decides to do so by a majority of those present.  T.C.A. § 5-5-110.
