Utah Constitutional Amendment 3 was an amendment to the Utah state constitution that sought to define marriage as a union exclusively between a man and woman. It passed in the November 2, 2004, election, as did similar amendments in ten other states.
The amendment, which added Article 1, Section 29, to the Utah Constitution, reads:
Marriage consists only of the legal union between a man and a woman.
No other domestic union, however denominated, may be recognized as a marriage or given the same or substantially equivalent legal effect.
