The Federal Marriage Amendment (FMA), also referred to by proponents as the Marriage Protection Amendment, was a proposed amendment to the United States Constitution that would legally define marriage as a union of one man and one woman. The FMA would also prevent judicial extension of marriage rights to same-sex (gay) or other unmarried homosexual couples.
Ballot Measure 36 was a 2004 initiative in the U.S. state of Oregon. It amended the Oregon Constitution to define marriage as a union of one man and one woman. The initiative passed with 1,028,546 votes in favor, and 787,556 votes against in the November 2, 2004 general election. It is one of a number of U.S. state constitutional amendments banning same-sex marriage. However, unlike other similar ballot measures passed on or near the same election date, the amendment did not explicitly ban civil unions between same-sex couples.
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.
Prior to the Supreme Court's decision in Obergefell v. Hodges (2015), U.S. state constitutional amendments banning same-sex unions of several different types passed, banning legal recognition of same-sex unions in U.S. state constitutions, referred to by proponents as "defense of marriage amendments" or "marriage protection amendments." These state amendments are different from the proposed Federal Marriage Amendment, which would ban same-sex marriage in every U.S. state, and Section 2 of the Defense of Marriage Act, more commonly known as DOMA, which allowed the states not to recognize same-sex marriages from other states. The amendments define marriage as a union between one man and one woman and prevent civil unions or same-sex marriages from being legalized, though some of the amendments bar only the latter. The Obergefell decision in June 2015 invalidated these state constitutional amendments insofar as they prevented same-sex couples from marrying, even though the actual text of these amendments remain written into the state constitutions.

This prohibited same-sex marriages within the state, reinforcing previously existing statutes to the same effect until it was overturned by the Obergefell v. Hodges ruling in June 2015.

The constitutional amendment created by Referendum 1 has been effectively nullified since June 26, 2015, when the United States Supreme Court ruled in Obergefell v. Hodges that state-level bans on same-sex marriage are unconstitutional.
