Arizona v. Navajo Nation where a 5-4 majority ruled that the U.S. government has no affirmative duty to secure water for the Navajo Tribe under its 1868 treaty with the United States. The majority’s decision in Navajo Nation mischaracterizes the Navajo’s claims, applies an unsuitable legal framework, and undermines the trust obligations traditionally held by the federal government toward Indigenous tribes. Located in an arid region with severe water scarcity exacerbated by climate change, the Navajo Nation struggles with inadequate access to water, directly impacting a significant portion of its residents.
After a critique of the majority opinion, this Note explores Navajo Nation’s detrimental impact on tribal water rights and the federal trust relationship. It provides a historical context of tribal water rights under the Winters doctrine and examines the complex legal framework of the “Law of the River,” detailing how tribes, including the Navajo, were systematically excluded from the Colorado River Compact and other agreements critical to regional water allocation. This backdrop highlights the Navajo Nation’s longstanding struggle for water access and the federal government’s historical role in the crisis. The Court’s decision not only denies meaningful judicial recourse for the Navajo Nation but also signals a concerning shift in the federal trust relationship and tribal water rights. This Note concludes by considering what recourse the Navajo Nation have, and advocates for the judiciary to analyze the scope of the federal government’s trust responsibility in a manner that ensures the United States honors its treaty obligations.
