On March 20, 2023, the Supreme Court heard oral argument in the consolodated cases of Arizona v. Navajo Nation and Dep. of Interior v. Navajo Nation. At issue is whether the federal government has an affirmative duty to the Navajo Nation to assess and provide for the Nation's water needs from particular sources, given that such a duty was not expressly established in past treaties between the federal government and the Nation. Join us to hear from Prof. Tom Gede as he breaks down the case.
