Narrative Opinion Summary
This case delves into the legal determination of whether the Yankton Sioux Reservation was diminished by the 1894 Act, which ratified the 1892 agreement between the Yankton Sioux Tribe and the United States for the cession of unallotted tribal lands in exchange for $600,000. The Tribe and the federal government argued that the reservation boundaries remained intact, whereas the State claimed that the Act diminished the reservation, thus assuming jurisdiction over the land. The District Court ruled in favor of the Tribe, maintaining reservation boundaries, a decision upheld by the Eighth Circuit. However, the Supreme Court reversed this decision, concluding that the language of the 1894 Act clearly indicated congressional intent to diminish the reservation. The Court emphasized that the cession of unallotted lands and fixed payment created a strong presumption of diminishment, with state jurisdiction applying to these lands. The decision was based on the statutory language, historical context, and the subsequent treatment of the land, despite ambiguous references in legislative and executive actions. This ruling clarifies that the landfill site, previously within the reservation's original boundaries, is no longer classified as 'Indian country,' granting primary jurisdiction to the State. The Court's decision underscores the necessity of explicit congressional intent in altering tribal land status and the importance of resolving ambiguities in favor of tribes, while also acknowledging the impact of historical policies on current jurisdictional challenges.
