Congressional & Legislative
Primary Authority: Congressional and legislative maps are enacted by the Tennessee General Assembly, subject to the Governor’s veto. The General Assembly can override a veto with a majority vote in each chamber. Republicans currently have a veto-proof majority in both chambers. [Tenn. Const. art. II, §§ 3 – 6; Tenn. Code Ann. §§ 3-1-101 – 3-1-103]
If a bill is presented to the governor during or after session, the governor has 10 days to sign or veto it; otherwise, it becomes law without signature. Sundays and days of delivery are excluded from these calculations.
Mapping Timeline: Not specified for congressional plans. The General Assembly is generally required to enact legislative plans after the decennial census results are available, but no deadline is specified. [Tenn. Const. art. II, § 4]
Redistricting Criteria: Contiguous; No counties divided unless necessary (max 30 counties split); Substantially equal population; No split precincts (must be changed after maps passed to conform). [Tenn. Const. art. II, §§ 4 – 6; Tenn. Code Ann. §§ 3-1-102 – 3-1-103]
Map Challenges: Not specified.
Ballot Measure & Referendum Processes
Types of Measures: Only the Tennessee General Assembly can refer amendments to the ballot. There is no initiative or referendum process. [Tenn. Const. art. XI, § 3]
