Sioux Tribe Jurisdiction Ruling

Date: April 5, 1977 • Location: Bloomingdale, United States

The US Supreme Court rules that congressional legislation that diminished the size of the Sioux people's reservation thereby destroyed the tribe's jurisdictional authority over the area in Rosebud Sioux Tribe v. Kneip.

The Supreme Court of the United States (SCOTUS) is the highest court in the federal judiciary of the United States. It has ultimate appellate jurisdiction over all U.S. federal court cases, and over state court cases that turn on questions of U.S. constitutional or federal law. It also has original jurisdiction over a narrow range of cases, specifically "all Cases affecting Ambassadors, other public Ministers and Consuls, and those in which a State shall be Party". In 1803, the court asserted the power of judicial review, the ability to invalidate a statute for violating a provision of the Constitution. It is also able to strike down presidential directives for violating either the Constitution or statutory law.
