Supreme Court divided on Navajo Nation water rights case.

The Supreme Court is divided over a dispute between the Navajo Nation and the federal government regarding the tribe's water rights from the drought-stricken Colorado River. States and water districts urged the court to rule against the tribe, while the Navajo Nation argued for an assessment of their water needs. The federal government warned that siding with the tribe could lead to lawsuits from other tribes. The case involves two treaties signed in 1849 and 1868, with the Navajo Nation arguing that the second treaty promised a sufficient supply of water. A decision is expected by the end of June.
