In Arizona v. Navajo Nation, the U.S. Supreme Court rejected the Navajo Nation’s claim that the 1868 treaty establishing the Navajo Reservation required the United States to take affirmative steps to secure water for the Tribe. In a 5-4 opinion, the Court reversed the Ninth Circuit and concluded that, although it is well-settled that reservations of lands for Indian Tribes implicitly include the right to use water necessary to accomplish the purposes of the reservation, the Navajo Nation could not maintain its action for breach of trust because the relevant 1868 treaty between the Navajo Nation and the United States did not include language imposing an affirmative duty on the United States to secure that water.
The Navajo Nation brought a claim related to the Colorado River, asserting that the “permanent home” language from the 1868 treaty included a water supply adequate to sustain agriculture and livestock on the Reservation. According to the Navajo Nation, by failing to take affirmative steps to secure water for those purposes, the United States, which holds water rights in trust for the Navajo Nation, had breached its fiduciary duty.
The Court concluded that, to sustain its breach-of-trust claim, the Navajo Nation needed to identify the text of a treaty, statute, or regulation imposing on the United States an affirmative duty to secure water for the Navajo Nation. Although the 1868 treaty imposed certain affirmative duties on the federal government, including for the supply of seeds and agricultural implements for up to three years, it did not contain language recognizing an affirmative duty to secure water for such purposes. According to the Court, although the United States has a general trust relationship with Indian Tribes, including the Navajos, that relationship does not include “all the fiduciary duties of a private trustee,” and the Court would not infer a conventional trust relationship with regard to a particular trust asset (such as water) without express language creating that duty.
Notably, this could affect hydropower developments when dealing with challenges to water use brought by Tribal nations by eliminating some insecurity as to the viability and extent of such claims. It is also consistent with FERC’s longstanding view that it fulfills its trust responsibilities to Tribes by accommodating Tribal interests to the extent Congress has directed in the Federal Power Act and not by prioritizing those interests.
