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, and it became Article I-29 of the state's Constitution. The initiative has since been struck down in federal court and same-sex marriage is now legally recognized in the state of Nebraska.
As of April 2025, Article I-29 of the Nebraska Constitution remains an unconstitutional constitutional amendment. It can repealed by either an initiated constitutional amendment, a state constitutional convention, or by a legislatively referred constitutional amendment that requires a three-fifths vote in the Nebraska Legislature and a majority vote in a referendum.
