Supreme Court of the Navajo Nation

The Supreme Court of the Navajo Nation is the highest judicial Native American authority of the Navajo Nation, the largest American Indian nation in the United States. According to Harvard Law School, "the judicial system of the Navajo Nation is the most active tribal judicial system in the United States, with a case load that rivals, and in some instances exceeds, many municipal, county, and state judicial systems."

The Supreme Court of the Navajo Nation sits in Window Rock. It is a three-member body consisting of the Chief Justice JoAnn Jayne, and Associate Justices Eleanor Shirley and Tina Tsinigine.

History
The Supreme Court of the Navajo Nation was originally created as the Navajo Tribal Court of Appeals on 1 April 1959 as part of the implementation of the Navajo Tribal Council's establishment of the judiciary as a separate branch of government, the "Judicial Branch of the Navajo Nation Government". Originally it was the court of last resort on the Navajo Nation. From 1978 to 1985 the "Supreme Judicial Council", a political body rather than a court, could hear appeals, on a discretionary basis, from the Navajo Tribal Court of Appeals.

In December 1985 the Supreme Judicial Council was eliminated and the Navajo Tribal Court of Appeals became the Supreme Court of the Navajo Nation. It was expressly made the court of last resort.
