North Dakota Measure 1 was a 2024 North Dakota ballot initiative which, if allowed to be enforced, would prohibit the election or appointment of any individual who would turn 81 years old by December 31 of that year.
The initiative was passed in a landslide, but is currently blocked from enforcement by the U.S. Supreme Court's ruling in U.S. Term Limits, Inc. v. Thornton (1995).
The initiative requires that, "in the case of a court ruling blocking the enforcement of the age limit, any candidate who would be restricted from serving due to the age limit, would be barred from appearing on the ballot to be nominated or elected to serve in the House or Senate. If a court ruling requires such a candidate to appear on the ballot, the initiative would require a note on ballots next to the candidate's name stating the candidate's age at the end of their term." The initiative would require the North Dakota Attorney General to defend all portions of the law in state and federal court.
