US SUPREME COURT DECISIONS

Both the language and legislative history of the Acts of 1904, 1907, and 1910, whereby land in certain counties in South Dakota located within the boundaries of the Rosebud Sioux Reservation as defined in an 1889 Treaty was required to be ceded by the Reservation Indians to the Government for sale to settlers under the homestead and townsite laws with the proceeds to be credited to the Indians only as received or, with respect to certain parcels, for transfer to South Dakota for school use, held clearly to evidence a congressional intent to diminish the boundaries of the Reservation. Although such Acts were unilateral Acts of Congress without the consent of three-fourths of the Rosebud Sioux Tribe's adult male members, as was required by the original 1868 Treaty establishing the Reservation, that fact does not directly bear on the question whether Congress, by these later Acts, intended to diminish the Reservation boundaries. Nor is it conclusive with respect to congressional intent that these Acts changed the method of payment from an outright, fixed-sum payment to the Indians required by a 1901 Agreement that would have amended the 1889 Treaty and would have resulted in a diminution of the Reservation boundaries, but which, although approved by three-fourths of the Tribe's adult male members, was never ratified by Congress. Pp. 430 U. S. 586-615.
