Tennessee Amendment 1 of 2006 (also known as the Tennessee Marriage Protection Amendment) is a state constitutional amendment banning same-sex unions. The referendum was approved by 81% of voters. It specifies that only a marriage between a man and a woman can be legally recognized in the state of Tennessee. This effectively prohibits same-sex marriages within the state, reinforcing previously existing statutes to the same effect.
