Yankton Sioux Tribe v. U.S. Army Corps of Engineers

Issue: The court of appeals held in this case that land transfers by the United States Army Corps of Engineers to the State of South Dakota pursuant to the Water Resources Development Act of 1999 did not violate §§ 605(b)(3) and (c)(1)(B) of that Act because they did not include lands within the “external boundaries”? of the Yankton Sioux Reservation. The petitions and conditional cross-petition for a writ of certiorari in Nos. 10-929, 10-931, and 10-932 concern the boundaries of that reservation. The question presented is whether to hold this petition and then dispose of it as appropriate in light of the Court's disposition of those other petitions.
