Countywide officeholders, such as the county mayor, sheriff, trustee, register, county clerk, or assessor of property, are statutorily prohibited from being nominated for or elected to membership in the county legislative body.  T.C.A. § 5‑5‑102.  However, county employees may hold the office of county legislative body member.  Any county employee who is otherwise qualified may serve as a member of the county legislative body, notwithstanding the fact that such person is a county employee.  T.C.A. § 5‑5‑102.

In 2016, the Legislature enacted Public Chapter 1072, effective May 20, 2016. This new law changes the conflict of interest provisions for county commissioners who are county employees or whose spouses are county employees. Pursuant to the new law, no member of the county legislative body who is also an employee of the same county or whose spouse is an employee of the same county may vote on matters in which the member has a conflict of interest. The new law provides that a conflict of interest is created when a member is voting on a matter which, if approved by the legislative body, would increase the pay or benefits of that member or that member's spouse. However, the new law does not prohibit a member from voting on the budget, appropriation resolution, or tax rate resolution, or amendments thereto, unless the vote is on a specific amendment to the budget or a specific appropriation or resolution in which the member has a conflict of interest. If a member of a county governing body who is voting on a proposed budget, appropriation resolution, or tax rate resolution, or amendments thereto, has a conflict of interest, then the member must declare the conflict of interest at the meeting prior to casting the member’s vote. A member who abstains from voting for cause on any issue coming to a vote before the body is not counted for the purpose of determining a majority vote. These new provisions have been codified as T.C.A. § 5-5-112.
