North Dakota Constitutional Measure 1 of 2004, is an amendment to the North Dakota Constitution that makes it unconstitutional for the state to recognize or perform same-sex marriages or civil unions. The referendum was approved by 73% of the voters.
The text of the amendment states: <blockquote>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. </blockquote>Due to the Supreme Court's 2015 ruling in Obergefell v. Hodges (576 U.S. 644), which legalized same-sex marriage across the United States, this amendment is unenforceable.
