WASHINGTON (AP) – The Supreme Court has refused to get involved in a long-running dispute on the continued existence of the Yankton Sioux Tribe and the extent of its lands in South Dakota.

The justices on Monday let stand several rulings involving the tribe, including an appeals court decision saying the reservation covers more than 30,000 acres, which is mostly land the federal government holds in trust for the tribe and individual tribal members.

The high court also rejected an appeal from the tribe to block the transfer of two federal recreation areas along the Missouri River to the state of South Dakota.

The cases are Daugaard v. Yankton Sioux Tribe, 10-929; Southern Missouri Recycling v. Yankton Sioux Tribe, 10-931; Hein v. Yankton Sioux Tribe, 10-932; and Yankton Sioux Tribe v. Daugaard, 10-1058.
