The Supreme Court has ruled against the Navajo Nation in a dispute involving water from the drought-stricken Colorado River. States that draw water from the river — Arizona, Nevada and Colorado — and water districts in California had urged the court to decide for them, and that's what the justices did. Colorado said siding with the Navajo Nation would undermine existing agreements and disrupt the river's management. The Biden administration said that if the court ruled for the Navajo Nation, the government could face lawsuits from many other tribes. The Navajo Nation's president says the ruling is “disappointing" and lawyers are reviewing it. A lawyer who represented states opposing the tribe’s claims says the justices “ruled exactly right.”
