Arizona Proposition 107 was a proposed same-sex marriage ban, put before voters by ballot initiative in the 2006 general election. If passed, it would have prohibited the state of Arizona from recognizing same-sex marriages or civil unions. The state already had a statute defining marriage as the union of a man and a woman and prohibiting the recognition of same-sex marriages performed elsewhere. This proposed amendment to the Arizona Constitution failed, with 48.2% voting in favor and 51.8% opposed, making Arizona the first U.S. state to defeat a state constitutional amendment banning same-sex marriage. Several states approved similar measures between 1998 and 2006. The proposition was backed by the Protect Marriage Arizona coalition, which included the Center for Arizona Policy and United Families Arizona. The proposition was primarily opposed by the Arizona Together coalition, which included the Arizona Human Rights Fund and the Human Rights Campaign. Voters approved a more limited constitutional amendment which banned same-sex marriage but not state-recognized civil unions or domestic partnerships, 2008 Arizona Proposition 102, in 2008 with 56% of the vote.
