Department of Interior v. Navajo Nation
The Facts
The Navajo Nation has struggled with severe water scarcity on its reservation for decades, many residents lack running water. The Nation sued the federal government, arguing that the trust relationship established by the 1868 Treaty of Bosque Redondo imposed an affirmative duty on the United States to secure water for the reservation. The Navajo sought a judicial declaration that the government must assess the Nation's water needs and develop a plan to meet them from the Colorado River and other sources.
The Conclusion
**The Supreme Court held 5-4 (Kavanaugh writing) that neither the 1868 treaty, relevant statutes, nor general trust principles impose a duty on the federal government to take affirmative steps to secure water for the Navajo Nation.** The treaty promised a reservation, not a guarantee of water. Decided June 22, 2023.
