ARIZONA ET AL. v. NAVAJO NATION ET AL. CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR THE NINTH CIRCUIT No. 21–1484. Argued March 20, 2023—Decided June 22, 2023
An 1868 peace treaty between the United States and the Navajo Tribe established the Navajo Reservation that today spans some 17 million acres, almost entirely in the Colorado River Basin of the western United States. The Federal Government’s reservation of land for an Indian tribe implicitly reserves the right to use needed water from various sources—such as groundwater, rivers, streams, lakes, and springs—that arise on, border, cross, underlie, or are encompassed within the reservation. See Winters v. United States, 207 U. S. 564, 576–577. While the Tribe has the right to use needed water from the reservation’s numerous water sources, the Navajos face the same water scarcity problem that many in the western United States face. In the Navajos’ view, the Federal Government’s efforts to assist the Navajos with their water needs did not fully satisfy the trust obligations of the United States under the 1868 treaty. The Navajos filed suit seeking to compel the United States to take affirmative steps to secure needed water for the Tribe—including by assessing the Tribe’s water needs, developing a plan to secure the needed water, and potentially building pipelines, pumps, wells, or other water infrastructure. The States of Arizona, Nevada, and Colorado intervened against the Tribe to protect those States’ interests in water from the Colorado River. The U. S. District Court for the District of Arizona dismissed the Navajo Tribe’s complaint, but the Ninth Circuit reversed, holding in relevant part that the United States has a duty under the 1868 treaty to take affirmative steps to secure water for the Navajos.
Held: The 1868 treaty establishing the Navajo Reservation reserved necessary water to accomplish the purpose of the Navajo Reservation but did not require the United States to take affirmative steps to secure water for the Tribe. Pp. 6–13.
(a) The Tribe asserts a breach-of-trust claim based on its view that the 1868 treaty imposed a duty on the United States to take affirmative steps to secure water for the Navajos. To maintain such a claim here, the Tribe must establish, among other things, that the text of a treaty, statute, or regulation imposed certain duties on the United States. See United States v. Jicarilla Apache Nation, 564 U. S. 162, 173–174, 177–178. The Federal Government owes judicially enforceable duties to a tribe “only to the extent it expressly accepts those responsibilities.” Id., at 177. Whether the Government has expressly accepted such obligations “must train on specific rights-creating or duty-imposing” language in a treaty, statute, or regulation. United States v. Navajo Nation, 537 U. S. 488, 506.
Here, while the 1868 treaty “set apart” a reservation for the “use and occupation of the Navajo tribe,” 15 Stat. 668, it contains no language imposing a duty on the United States to take affirmative steps to secure water for the Tribe. See Navajo Nation, 537 U. S., at 506. Notably, the 1868 treaty did impose a number of specific duties on the United States, but the treaty said nothing about any affirmative duty for the United States to secure water. As this Court has stated, “Indian treaties cannot be rewritten or expanded beyond their clear terms.” Choctaw Nation v. United States, 318 U. S. 423, 432.
To be sure, this Court’s precedents have stated that the United States maintains a general trust relationship with Indian tribes, including the Navajos. Jicarilla, 564 U. S., at 176. But unless Congress has created a conventional trust relationship with a tribe as to a particular trust asset, this Court will not “apply common-law trust principles” to infer duties not found in the text of a treaty, statute, or regulation. Id., at 178. Here, nothing in the 1868 treaty establishes a conventional trust relationship with respect to water. And it is unsurprising that a treaty enacted in 1868 did not provide for all of the Navajos’ current water needs 155 years later. Under the Constitution, Congress and the President have the responsibility to update federal law as they see fit in light of the competing contemporary needs for water.

| The "slip" opinion is the second version of an opinion. It is sent to the printer later in the day on which the "bench" opinion is released by the Court.

Caution: These electronic opinions may contain computer-generated errors or other deviations from the official printed slip opinion pamphlets. Moreover, a slip opinion is replaced within a few months by a paginated version of the case in the preliminary print, and—one year after the issuance of that print—by the final version of the case in a U.

In case of discrepancies between the slip opinion and any later official version of the opinion, the later version controls. (source: http://www.supremecourt.gov/opinions/slipopinions.aspx) ||
