Tennessee Code Title 40. Criminal Procedure § 40-20-114

(a) A person who has been convicted in this state of an infamous crime, as defined by § 40-20-112, other than one specified in subsection (b), or convicted under the laws of the United States or another state of an offense that would constitute an infamous crime if committed in this state, shall be disqualified from qualifying for, seeking election to or holding a public office in this state, unless and until that person's citizenship rights have been restored by a court of competent jurisdiction.

(b) Notwithstanding the provisions of subsection (a) to the contrary, a person convicted in this state of an infamous crime, as defined by § 40-20-112, or convicted under the laws of the United States or another state of an offense that would constitute an infamous crime if committed in this state, and the offense was committed while that person is holding an elected public office at the federal level, or in this or any other state or any political subdivision of this or any other state, shall be forever disqualified from qualifying for, seeking or holding any public office in this state or any political subdivision of this state, if the offense was committed in the person's official capacity or involved the duties of the person's office. This subsection (b) shall apply even if the person's citizenship rights have been restored, but shall not be construed as limiting the restoration of any other citizenship rights, including the right of suffrage provided for in § 2-2-139, § 2-19-143, or § 40-29-105.

(c) If a person is holding an elected public office and was convicted of an infamous crime pursuant to the qualifications in subsection (b) that was committed prior to July 1, 2007, the person shall be allowed to remain in office for the remainder of the term, but shall forever be prohibited from qualifying for, seeking or holding any public office in this state or political subdivision of this state after July 1, 2007, or when the term expires or when the person vacates the office, whichever is first.

(d) If a person is holding an elected public office and is convicted of an infamous crime pursuant to the qualifications in subsection (b) that was committed on or after July 1, 2007, the conviction shall be grounds for removal from office in the manner provided by law and the person shall forever be prohibited from qualifying for, seeking or holding any public office in this state or political subdivision of this state after July 1, 2007.

(e) A court shall not accept any plea agreement that allows an elected public official who is charged with an infamous crime involving an offense committed in the person's official capacity or involving the duties of the person's office, to qualify for, seek, or hold public office in this state or any political subdivision of this state at some point in the future. If an elected public official accepts a plea agreement for an offense committed in the person's official capacity or involving the duties of the person's office, the person is prohibited from qualifying for, seeking, or holding public office in this state or any political subdivision of this state at some point in the future after the plea agreement has been agreed to by all parties.

(f) If any provision of this section or the application of this section to any person or circumstance is held invalid, the invalidity shall not affect other provisions or applications of the section that can be given effect without the invalid provision or application, and to that end this section is declared to be severable.
