Tenn. Const. art. XI, § 9

The Legislature shall have the right to vest such powers in the Courts of Justice, with regard to private and local affairs, as may be expedient.

The General Assembly shall have no power to pass a special, local or private act having the effect of removing the incumbent from any municipal or county office or abridging the term or altering the salary prior to the end of the term for which such public officer was selected, and any act of the General Assembly private or local in form or effect applicable to a particular county or municipality either in its governmental or its proprietary capacity shall be void and of no effect unless the act by its terms either requires the approval of a two-thirds vote of the local legislative body of the municipality or county, or requires approval in an election by a majority of those voting in said election in the municipality or county affected.

Any municipality may by ordinance submit to its qualified voters in a general or special election the question: “Shall this municipality adopt home rule?”

In the event of an affirmative vote by a majority of the qualified voters voting thereon, and until the repeal thereof by the same procedure, such municipality shall be a home rule municipality, and the General Assembly shall act with respect to such home rule municipality only by laws which are general in terms and effect.

Any municipality after adopting home rule may continue to operate under its existing charter, or amend the same, or adopt and thereafter amend a new charter to provide for its governmental and proprietary powers, duties and functions, and for the form, structure, personnel and organization of its government, provided that no charter provision except with respect to compensation of municipal personnel shall be effective if inconsistent with any general act of the General Assembly and provided further that the power of taxation of such municipality shall not be enlarged or increased except by general act of the General Assembly. The General Assembly shall by general law provide the exclusive methods by which municipalities may be created, merged, consolidated and dissolved and by which municipal boundaries may be altered.

A charter or amendment may be proposed by ordinance of any home rule municipality, by a charter commission provided for by act of the General Assembly and elected by the qualified voters of a home rule municipality voting thereon or, in the absence of such act of the General Assembly, by a charter commission of seven (7) members, chosen at large not more often than once in two (2) years, in a municipal election pursuant to petition for such election signed by qualified voters of a home rule municipality not less in number than ten (10%) percent of those voting in the then most recent general municipal election.

It shall be the duty of the legislative body of such municipality to publish any proposal so made and to submit the same to its qualified voters at the first general state election which shall be held at least sixty (60) days after such publication and such proposal shall become effective sixty (60) days after approval by a majority of the qualified voters voting thereon.

The General Assembly shall not authorize any municipality to tax incomes, estates, or inheritances, or to impose any other tax not authorized by Sections 28 or 29 of Article II of this Constitution. Nothing herein shall be construed as invalidating the provisions of any municipal charter in existence at the time of the adoption of this amendment.

The General Assembly may provide for the consolidation of any or all of the governmental and corporate functions now or hereafter vested in municipal corporations with the governmental and corporate functions now or hereafter vested in the counties in which such municipal corporations are located; provided, such consolidations shall not become effective until submitted to the qualified voters residing within the municipal corporation and in the county outside thereof, and approved by a majority of those voting within the municipal corporation and by a majority of those voting in the county outside the municipal corporation.
