On January 13, 2024, the U.S. Supreme Court decided the Walen v. Burgum redistricting lawsuit and affirmed the U.S. District Court for the District of North Dakota decision that preserves North Dakota House District 4A, a subdistrict that gives Mandan, Hidatsa, and Arikara Nation voters a long-awaited opportunity to elect representatives of their choice. The lower court determined that state legislators were endeavoring to comply with Section 2 of the Voting Rights Act and redistricting best practices by creating an election subdistrict along the boundaries of the MHA reservation as part of 2021 redistricting.
While the MHA Nation sided with the state to defend subdistrict 4A, North Dakota abandoned its own win during the appeal to the Supreme Court, failing to advocate for the state legislature’s voting map and citizens’ rights.
