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."[1]
The Supreme Court of the Navajo Nation sits in Window Rock.[2] It is a three-member body consisting of the Chief Justice JoAnn Jayne, and Associate Justices Eleanor Shirley and Tina Tsinigine.[3]
