The Supreme Court has ruled against the Navajo Nation in a case centered on the tribe鈥檚 rights to the drying Colorado River. 

The tribe claimed it was the federal government鈥檚 legal duty to help figure out their future water needs, and aid them in using their rights. But in a 5-4 decision, the justices said an 1868 treaty included no such promises.

In the majority opinion comprised of the court鈥檚 conservative wing, Justice Brett Kavanaugh wrote that the agreement between the Navajo Nation and the federal government set aside water for use on the reservation that stretches more than 25,000 square miles across an arid reach of Utah, Arizona and New Mexico, but it did not create a duty for the federal government to help the tribe secure that water.

鈥淭he 1868 treaty reserved necessary water to accomplish the purpose of the Navajo Reservation,鈥� Kavanaugh wrote. 鈥淏ut the treaty did not require the United States to take affirmative steps to secure water for the Tribe.鈥�

In a dissenting opinion, Justice Neil Gorsuch wrote that the majority both misunderstands the tribe鈥檚 claims and applies an incorrect legal framework in making its decision. The tribe has tried different legal avenues to gain the assistance it needs and work to quantify its water rights, he wrote.

鈥淲here do the Navajo go from here?鈥� Gorsuch wrote in his opinion. 鈥淭o date, their efforts to find out what water rights the United States holds for them have produced an experience familiar to any American who has spent time at the Department of Motor Vehicles. The Navajo have waited patiently for someone, anyone, to help them, only to be told (repeatedly) that they have been standing in the wrong line and must try another.鈥�

More than a third of Navajo Nation residents lack access to clean water in their homes. The tribe experienced some of the highest infection rates in the country during the COVID-19 pandemic, which spurred a new sense of urgency around public health and hygiene and to address the tribe鈥檚 gap between water supply and demand.

Some of the tribe鈥檚 water rights in the Colorado River basin have been quantified, such as in the portions of the reservation in Utah and New Mexico. But in Arizona, where the vast majority of the reservation lies, the tribe鈥檚 water is not quantified and settled, which leaves unanswered questions about how much water the tribe might end up using from the Colorado River. That uncertainty over future river management spurred the states of Colorado, Nevada and Arizona to urge the Supreme Court to decide in their favor.

鈥淭oday鈥檚 ruling is disappointing and I am encouraged that the ruling was 5-4," said Navajo Nation president Buu Nygren in a statement. "It is reassuring that four justices understood our case and our arguments. As our lawyers continue to analyze the opinion and determine what it means for this particular lawsuit, I remain undeterred in obtaining quantified water rights for the Navajo Nation in Arizona. The Navajo Nation established a water rights negotiation team earlier this year and we are working very hard to settle our water rights in Arizona."

The process to quantify and settle water rights varies from tribe to tribe but can drag on for decades, depending on their complexity and the number of stakeholders involved.

鈥淓ver since this case started, what the issue is has been framed in a lot of different ways,鈥� said Heather Tanana, a University of Utah law professor and citizen of the Navajo Nation. 鈥滻t鈥檚 that misframing and warping of what the Nation was actually asking that resulted in that, in my opinion, wrong decision.鈥�

This new ruling will not lead to immediate on-the-ground effects in the tribe鈥檚 desire to use its water rights, Tanana said. Recently allocated funds from the Bipartisan Infrastructure and Jobs Act and the Inflation Reduction Act have begun to flow to some tribes, including the Navajo Nation, to build water supply projects. The burden will remain on tribes to plan for their future uses and to secure and use the water they are legally entitled to, she said.

鈥淭he status quo is going to continue,鈥� Tanana said. 鈥淏eing disappointed by the federal government is nothing new in Indian Country.鈥�
