Donnelly v. United States

Background

A white man was tried in federal court for the murder of Chickasaw, an Indian, at the edge of the Klamath River inside the area called the Extension of the Hoopa Valley Reservation. He was convicted and sentenced to life. He argued the court lacked jurisdiction because the killing took place in the river (outside the reservation) and because he was not an Indian; he also sought to admit testimony that another Indian, Joe Dick, had confessed to the killing.

Reasoning

The Court held that the 1891 presidential order lawfully extended the Hoopa Valley Reservation and that the description included the Klamath River bed. California law and historical practice showed the United States owned the riverbed, so it could be part of the reservation. The Court rejected mining‑claim and school‑district arguments as insufficient to defeat the extension. It concluded that land set apart from the public domain may be “Indian country” under the federal criminal statutes, so murder of an Indian by a non‑Indian on the reservation is punishable in federal court. The judge also properly excluded the out‑of‑court confession of Joe Dick as inadmissible hearsay.

Real world impact

The decision affirms federal authority to prosecute non‑Indians who kill Indians on federal reservations and upholds executive power to adjust reservation boundaries. Local land claims or county uses do not automatically override a lawful reservation. The ruling limits defenses based on third‑party out‑of‑court confessions, which remain generally inadmissible.

Dissents or concurrances

Justice Holmes (joined by Lurton and Hughes) dissented on the exclusion of the confession, arguing declarations against interest should sometimes be admitted; Justice Van Devanter concurred only in the result.
