What it's about

The Winnemucca Indian Colony asks the Supreme Court to review the dismissal of its claim that the federal government breached trust duties by failing to protect water and other natural resources on the Tribe’s trust lands from third-party trespass and theft. The case concerns whether federal laws, regulations, and the government’s control over Indian water resources allow the Tribe to seek money damages from the United States.

Question presented

1. Is the United States’ promise to provide the Winnemucca Indian Colony, a federally recognized Tribe with lands held in trust established by an Executive Order and a separate legislative act, coupled with the government’s nearly exclusive statutory and regulatory control over the water on Indian lands, sufficient to entitle an Indian tribe to money damages when the United States breaches its fiduciary duty to protect the natural resources on those Indian lands? 2. Did the Federal Court of Appeals, Federal Circuit, err when it affirmed dismissal of the Winnemucca Indian Colony’s third claim for relief – Breach of Trust – Water? 3. Can the Winnemucca Indian Colony state a cognizable claim for breach of trust against the United States in relation to BIA failure to prevent trespass and theft of natural resources by third parties, under the Winters doctrine and 25 C.F.R. § 152.22?
