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 couples.
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.
The Tennessee Marriage Protection Amendment, also known as Tennessee Amendment 1 of 2006, is a state constitutional amendment banning same-sex unions. The referendum was approved by 81% of voters. It specified that only a marriage between a man and a woman could be legally recognized in the state of Tennessee. 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.
Wisconsin Referendum 1 of 2006 was a referendum on an amendment to the Wisconsin Constitution that would invalidate same-sex marriages or any substantially similar legal status. The referendum was approved by 59% of voters during the general elections in November 2006. All counties in the state voted for the amendment except Dane County, which opposed it. 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.
South Dakota Amendment C of 2006 is an amendment to the South Dakota Constitution to make it unconstitutional for the state to recognize or perform same-sex marriages, or to recognize civil unions, domestic partnerships, or other quasi-marital relationships regardless of gender. The referendum was approved on 7 November 2006 by 52% of the state's voters.
Proposition 2 was a referendum for a state constitutional amendment placed on the ballot by the Texas legislature and approved by the voters at the November 8, 2005 general election. The measure added a new provision to the Texas Constitution, Article 1, Section 32, which provides that "Marriage in this state shall consist only of the union of one man and one woman", and "This state or a political subdivision of this state may not create or recognize any legal status identical or similar to marriage." Texas thus became the nineteenth US state to adopt constitutional amendment banning same-sex marriage. It was the most populous state to adopt a constitutional ban on same-sex marriage until California passed its ban in November 2008. The amendment was later invalidated in June 2015 after the Supreme Court legalized same-sex marriage nationwide in the Obergefell v. Hodges decision, though the amendment remains in the Texas Constitution.
Nebraska Initiative 416, officially titled "Ban Same-Sex Marriage Act", was a 2000 ballot initiative that amended the Nebraska Constitution to make it unconstitutional for the state to recognize or perform same-sex marriage, same-sex civil unions or domestic partnerships. The referendum was approved on November 7, 2000, by 70% of the voters. The initiative has since been struck down in federal court and same-sex marriage is now legally recognized in the state of Nebraska.
Kentucky Constitutional Amendment 1 of 2004, is an amendment to the Kentucky Constitution that made it unconstitutional for the state to recognize or perform same-sex marriages or civil unions. The referendum was approved by 75% of the voters.
The Constitution of the State of Colorado is the foundation of the laws and government of the U.S. state of Colorado. The Colorado State Constitution was drafted on March 14, 1876; approved by Colorado voters on July 1, 1876; and took effect upon the statehood of Colorado on August 1, 1876. As of 2020, the constitution has been amended at least 166 times. The Constitution of Colorado derives its authority from the sovereignty of the people. As such, the people of Colorado reserved specific powers in governing Colorado directly; in addition to providing for voting for Governor, state legislators, and judges, the people of Colorado have reserved initiative of laws and referendum of laws enacted by the legislature to themselves, provided for recall of office holders, and limit tax increases beyond set amounts without explicit voter approval, and must explicitly approve any change to the constitution, often with a 55% majority. The Colorado state constitution is one of the longest in the United States.
Florida Amendment 2 is an amendment made to the constitution of the U.S. state of Florida in 2008. It added Article I, Section 27 to the constitution, which defines marriage as a union only between one man and one woman, and thus bans the creation of similar unions, such as civil unions or same-sex marriage.
Same-sex marriage has been legally recognized in Colorado since October 7, 2014. Colorado's state constitutional ban on same-sex marriage was struck down in state district court on July 9, 2014, and by the U.S. District Court for the District of Colorado on July 23, 2014. The Tenth Circuit Court of Appeals had already made similar rulings with respect to such bans in Utah on June 25 and Oklahoma on July 18, which are binding precedents on courts in Colorado. On October 6, 2014, the U.S. Supreme Court declined to hear the Tenth Circuit cases, and the Tenth Circuit lifted its stay. On October 7, the Colorado Supreme Court and the Tenth Circuit cleared the way for same-sex marriages to begin in Colorado.
Same-sex marriage has been legally recognized in Nevada since October 9, 2014, when a federal district court judge issued an injunction against enforcement of Nevada's same-sex marriage ban, acting on order from the Ninth Circuit Court of Appeals. A unanimous three-judge panel of the Ninth Circuit had ruled two days earlier that the state's ban on same-sex marriage was unconstitutional. Same-sex marriage was previously banned by an amendment to the Constitution of Nevada, which was approved by voters in 2002. The statutory ban on same-sex marriages was repealed by the Nevada Legislature in 2017, and the constitutional ban was repealed by voters in 2020 by 62–38 percent.
Same-sex marriage has been legal in Michigan since the U.S. Supreme Court's ruling in Obergefell v. Hodges on June 26, 2015. The U.S. state of Michigan had previously banned the recognition of same-sex unions in any form after a popular vote added an amendment to the Constitution of Michigan in 2004. A statute enacted in 1996 also banned both the licensing of same-sex marriages and the recognition of same-sex marriages from other jurisdictions.
Same-sex marriage has been legal in Ohio since the U.S. Supreme Court's ruling in Obergefell v. Hodges, a landmark decision in which the court struck down the state's statutory and constitutional bans on same-sex marriage on June 26, 2015. The case was named after plaintiff Jim Obergefell, who sued the state of Ohio after officials refused to recognize his marriage on the death certificate of his husband. Same-sex marriages were performed in Ohio beginning shortly after the Supreme Court released its ruling, as local officials implemented the order.
North Carolina Amendment 1 is a partially overturned legislatively referred constitutional amendment in North Carolina that amended the Constitution of North Carolina to add ARTICLE XIV, Section 6, which prohibit the state from recognizing or performing same-sex marriages, civil unions or civil union equivalents by defining male–female marriage as "the only domestic legal union" considered valid or recognized in the state. It did not prohibit domestic partnerships in the state and also constitutionally protected same-sex and opposite-sex prenuptial agreements, which is the only part that is still in effect today. On May 8, 2012, North Carolina voters approved the amendment, 61% to 39%, with a voter turnout of 35%. On May 23, 2012, the amendment took effect.
Same-sex marriage has been legal in Tennessee since the U.S. Supreme Court's ruling in Obergefell v. Hodges on June 26, 2015. Governor Bill Haslam quickly announced that the state would abide by the court's decision, and same-sex couples began to marry in Tennessee. Previously, Tennessee had banned same-sex marriage both by statute and its State Constitution.
Same-sex marriage has been legal in Virginia since October 6, 2014, following the decision of the U.S. Supreme Court not to hear an appeal of the Fourth Circuit Court of Appeals' ruling in Bostic v. Schaefer. Same-sex marriages subsequently began at 1:00 p.m. on October 6 after the Fourth Circuit issued its mandate, and since then Virginia has performed legal marriages of same-sex couples and recognized out-of-state same-sex marriages. Previously, the state had passed a statute prohibiting same-sex marriage in 1975, and further restrictions were added in 1997 and 2004, which made "void and unenforceable" any arrangements between same-sex couples bestowing the "privileges or obligations of marriage". Voters approved an amendment to the Constitution of Virginia reinforcing the existing laws in 2006. On January 14, 2014, a U.S. district court judge ruled in Bostic that Virginia's statutory and constitutional bans on the state recognition of same-sex marriages were unconstitutional, a decision upheld by the Fourth Circuit on July 28, 2014.
Same-sex marriage has been legal in Arkansas since the U.S. Supreme Court's landmark decision in Obergefell v. Hodges on June 26, 2015, striking down same-sex marriage bans nationwide. Prior to this, same-sex marriage in Arkansas was briefly legal for a period beginning on May 9, 2014, as a result of a ruling by Sixth Judicial Circuit Judge Chris Piazza striking down the state's constitutional and statutory bans on same-sex marriage as violating the U.S. Constitution. Approximately 541 same-sex couples received marriage licenses in several counties before the Arkansas Supreme Court stayed his ruling pending appeal on May 16, 2014.
Proposition 3, titled Constitutional Right to Marry, was a California ballot proposition and legislative statutes that passed by vote on in the 2024 general election on November 5, 2024. The proposition repealed Proposition 8 passed during the 2008 general election and amend the state constitution to declare that the "right to marry is a fundamental right". It also ensured that same-sex couples would have the right to marry in California in case the United States Supreme Court ever withdraws that federal right.
A referendum on the Amendment 1 to the Constitution of Hawaii was held on 5 November 2024. The amendment repealed the Hawaii's legislature's ability to limit marriage to heterosexual couples, reversing the 1998 Hawaii Amendment 2. The voters backed the measure by 51.3% of the valid votes; it succeeded in all four of Hawaii's major counties. The amendment passed simultaneously with similar ones in California and Colorado.
