Henkel v. United States

Background

A family who lived on about 800 acres inside the Blackfeet (Piegan) Reservation had built homes and improvements. In November 1906 the mother and her children signed a written relinquishment to the Commissioner of Indian Affairs, conditioned on payment of $7,500 for improvements and the right to later select replacement allotments. The United States paid $7,500 in February 1907 and later sought possession of the land to build a dam and reservoir as part of the Milk River reclamation project.

Reasoning

The Court addressed whether federal law allowed the Government to acquire these reservation lands despite earlier allotment statutes and a 1895 agreement that kept the reservation for communal grazing. It examined the 1902 Reclamation Act, which authorizes the Interior Secretary to acquire rights by purchase or condemnation and to take necessary actions to carry out irrigation projects, and the agreement language that reserved governmental rights for public improvements with compensation. The Court concluded Congress gave broad authority to acquire rights needed for reclamation, that the Secretary’s purchase and the written relinquishments were valid, and that the Secretary acted within his authority. The Court also accepted the Interior Department’s practice that a natural guardian may validly sign relinquishments for minor children.

Real world impact

The ruling affirms that federal reclamation projects can obtain reservation land when needed for public works, provided compensation and offers of replacement allotments are made. It supports Department practices about guardians signing for minors and affects tribal families who have occupied and improved reservation land. The decision clears the way for the Government to proceed with the Milk River reservoir project.
