The Supreme Court ruled 5-4 against the Navajo Nation in a dispute over water access from the Colorado River, saying that the 1868 treaty with the tribe did not require the U.S. government to take active steps to secure water access. The tribe had requested an assessment of their water rights, but the ruling means they will not receive the water access they had requested. Justice Brett Kavanaugh wrote for the majority, saying that it was not the judiciary's role to rewrite and update the 155-year-old treaty.
