TN Code § 6-20-102 (2021)
2021 Tennessee Code|Title 6 - Cities and Towns|Chapter 20 - Commissioners and Mayor Under City Manager-Commission Charter|Part 1 - Election of Commissioners|§ 6-20-102. Date of Elections

  The first election of commissioners in any city under Chapters 18 22 of this title shall be held on the fourth Tuesday following the election at which these chapters have been adopted. The board of commissioners shall fix the date of all subsequent elections; provided, that any date so designated shall fall within ninety (90) days of the annual anniversary of the first election of the board of commissioners.   In any city having a population of not less than three hundred seventy-five (375) nor more than four hundred twenty-five (425), in any county having a population of not less than twenty-eight thousand (28,000) nor more than twenty-eight thousand one hundred (28,100), all according to the 1970 federal census or any subsequent federal census, the board of commissioners shall fix the date of all subsequent elections; provided, that any date so designated shall be set at least one hundred twenty (120) days prior to the date such election is to be held. The presiding officer of the board of commissioners shall certify such election date, or any subsequent change thereto, to the secretary of state.    The board of commissioners may by ordinance change the date of municipal elections to coincide with the August or November general election. The ordinance changing the election date shall provide for the extension of the terms of members of the board necessary to meet the election date, but no term may be extended for more than two (2) years beyond its regular expiration date.   Nothing in subdivision (c)(1) shall be construed to remove any incumbent from office or abridge the term of any incumbent prior to the end of the term for which an elected official was selected.   If the board of commissioners changes the date of municipal elections pursuant to subdivision (c)(1), the board may at a later date change the election date back to what such date was prior to moving the election date to coincide with the August or November general election. The board may only make an election date change under this subdivision (c)(3) one (1) time. Terms of incumbent members of the board shall not be abridged to accomplish an election date change under this subsection (c); however, members elected at a date change pursuant to this subsection (c) may take office at a later date so as to not abridge terms of incumbent members. If such members take office at a later date, their term may be abridged due to such members having to take office at the later date.      In addition to the authority granted by subsections (a), (b) and (c), the board of commissioners of any municipality incorporated under the general laws of this state and having a population of not less than four hundred fifty (450) nor more than four hundred sixty (460), or not less than four hundred eight-five (485) nor more than four hundred ninety-four (494), that is located in any county having a population of not less than fifty-one thousand two hundred (51,200) nor more than fifty-one thousand three hundred (51,300), all according to the 2000 federal census or any subsequent federal census, may, by an ordinance approved by an affirmative two-thirds (2/3) vote of its membership, fix the date of subsequent regular municipal elections as the date of the regular November election as defined in § 2-1-104, by one (1) of the following alternative methods specified in the ordinance:  The terms of office of the incumbent members of the board of commissioners and popularly-elected mayor, if there is one, that would have expired on the date of the first regular municipal election occurring after the adoption of the ordinance shall be extended to the date of the regular state November election occurring thereafter. The terms of office of the incumbent members of the board of commissioners and popularly-elected mayor, if there is one, that would have expired on the date of the second regular municipal election occurring after the adoption of the ordinance shall be extended to the date of the regular state November election occurring thereafter; or   The terms of incumbent members of the board of commissioners, and the popularly-elected mayor, if there is one, that expire six (6) months or less before a regular state November election, shall be extended to the date of that state election. The terms of members of the board of commissioners and the popularly-elected mayor, if there is one, that expire more than six (6) months before a regular state November election shall be filled at the regular city election pertinent to those offices for terms extending to the next regular state November election.     Members of the board of commissioners, and the popularly-elected mayor, if there is one, shall be elected for terms of four (4) years, except for the transitional term provided for in subdivision (d)(1)(B).   Nothing in this subsection (d) shall be construed to remove any incumbent from office or abridge the term of any incumbent prior to the end of the term for which an elected official was selected.
