General Assembly - As introduced, authorizes the chair of a committee of the general assembly to require an executive branch employee to take an oath prior to testifying before the committee subject to the penalty of perjury; authorizes the chair of a committee or the executive director of fiscal review to require any documentation submitted by such employee for the purpose of evaluating the merits of a legislative measure or generating a fiscal note to submit an affidavit with such documentation attesting to the accuracy of the information subject to the penalty of perjury. - Amends TCA Title 3; Title 4; Title 29; Title 39 and Title 40.

SB 1721 requires state executive branch employees (such as department staff or governors' liaisons) to swear under oath that their testimony before legislative committees or their submitted fiscal documentation is truthful. If false statements are suspected, committee chairs or fiscal directors must notify legislative leaders, who may refer cases to district attorneys for potential perjury charges (classified as a Class C misdemeanor). The bill applies to all state departments and committees handling legislative measures or fiscal notes, directly affecting how executive branch staff provide information to lawmakers. It amends Tennessee Code Sections 3-3-121, 39-16-702, and related titles to establish this requirement and enforcement process. The law takes effect July 1, 2026.
