Chippewa Cree v. Chouteau County

On August 14, 2025, the Chippewa Cree Indians of the Rocky Boy’s Reservation and two Native voters filed a lawsuit in the U.S. District Court for the District of Montana challenging Chouteau County’s unfair, at-large voting system for the Board of County Commissioners. The suit alleges the system unlawfully dilutes the voting strength of Native voters and has denied them any representation on the county commission for more than a decade. Under the current at-large system, all voters in Chouteau County cast ballots for all three commissioners, instead of electing commissioners by district. As a result, Native voters — who now make up approximately one-third of the county’s voting-age population — have consistently been unable to elect a candidate of their choice. The three current commissioners have all been elected and re-elected under this system since at least 2010. For more information, read ACLU of Montana and NARF’s joint press release here.
