What Will the U.S. Supreme Court’s Decision on a Navajo Nation Water Rights Case Mean for Other Tribes?

The U.S. Supreme Court heard arguments Monday on a case that focuses on water access for the Navajo Nation but could impact battles for the resource across the West.

For 20 years, the Navajo Nation’s fight for water has been circulating through lower courts. The foundation of the case reaches back more than 150 years, involving the treaties that established the reservation, decades of court decisions and the United States’ legal responsibilities to the Navajo Nation.
