The Tennessee Senate has the power to pass resolutions concerning essentially any issue regarding the state, country, or world.

According to the Tennessee constitution, a county is not to be joined to a portion of another county for purposes of creating a district; this provision has been overridden by the rulings of the Supreme Court of the United States in Baker v. Carr (369 U.S. 182, 1962) and Reynolds v. Sims (337 U.S. 356, 1964).

The Tennessee constitution has been amended to allow that if these rulings are ever changed or reversed, a referendum may be held to allow the senate districts to be drawn on a basis other than substantially equal population.

Districts are to be sequentially and consecutively numbered; the scheme basically runs from east to west and north to south.

According to Article III, Section 12 of the Constitution of the State of Tennessee, the speaker of the Senate assumes the office of governor in the event of a vacancy.

The current speaker of the Senate and lieutenant governor is Randy McNally, who was elected to the position in 2017.
