Whether the Oneidas could maintain a federal common-law action to vindicate possessory rights in tribal land allegedly conveyed in violation of the 1793 Nonintercourse Act.
Holding
Yes. The Oneidas had a federal common-law cause of action for unlawful possession of tribal land.
Reasoning
Federal law has long recognized that Indian tribes possess a protected right of occupancy and use in their lands. Under the discovery doctrine, only the sovereign could acquire Indian land or extinguish Indian title. After the Constitution, Indian relations became an exclusively federal concern, so the Oneidas’ claimed possessory interest was a federal right.
The Court’s earlier decisions recognized, at least implicitly, that tribes may sue to enforce aboriginal title. Johnson v. McIntosh treated unauthorized private purchases of Indian land as invalid; Marsh v. Brooks recognized ejectment based on an Indian right of occupancy; and Santa Fe Pacific recognized a tribal claim for rents and profits against trespassers. These authorities supported a federal common-law remedy for the Oneidas’ alleged wrongful dispossession.
Because this established common-law cause of action resolved the case, the Court did not decide whether the 1793 Act itself also created an implied private right of action.
