Tennessee Code Title 4. State Government § 4-29-103

(a) The speakers of the senate and the house of representatives shall designate appropriate committees in their respective houses to conduct the review of governmental entities as provided in this chapter.

(b) The chairs of such committees shall appoint a subcommittee to conduct the review of each governmental entity.

(c) The appropriate subcommittees appointed in the senate and in the house of representatives shall meet as a joint committee as the evaluation committee to review each governmental entity assigned to such committee. There shall be an equal number of senators and representatives on the two (2) subcommittees and committees when meeting as a joint evaluation committee for the review of any specific governmental entity.

(d) Members of the evaluation committee shall serve until their successors are appointed in accordance with this section so long as such members remain members of the general assembly. Any member of the evaluation committee who ceases to be a member of the general assembly shall cease to be a member of the evaluation committee on the same date such member's membership in the general assembly ceases, as provided in the Constitution of Tennessee. In the event a majority of the membership of any subcommittee comprising an evaluation committee shall cease to be members of the general assembly, the speaker of the house in which such vacancies occur shall designate members of that house to interim appointments until such time as the evaluation committee is reconstituted as provided in this section.
