Tennessee Code Title 8. Public Officers and Employees § 8-10-109

(b)(1)(A) Notwithstanding any other law to the contrary, a county legislative body may, by adopting a resolution by a two-thirds ( 2/3 ) vote at two (2) consecutive meetings of the county legislative body, remove any law enforcement powers exercised by the constables of the county.

(B) Except as provided in subdivision (b)(1)(C), any such action by the county legislative body to remove such law enforcement powers shall apply to constables elected for terms of office following the expiration of the term of office of constables in office at the time such action is taken by the county legislative body.

(C) If during a constable's term of office, a constable is convicted of any felony or is removed from office under § 8-47-101 for knowingly or willfully committing misconduct in office, then with respect to such constable, the action of the county legislative body for removal of law enforcement powers shall become effective on the date such constable is removed from office or the date of the felony conviction; provided, however, that if the felony conviction is overturned and there is additional time remaining on the term of office for which the constable was elected, the law enforcement powers shall be restored to such constable until the end of such term of office.
