Oneida Indian Nation v. County of Oneida

Background

Two Oneida Indian Nations sued the counties that now occupy parts of their ancestral lands, alleging they once owned and occupied about six million acres in New York. The complaint said 18th‑century treaties and the federal Nonintercourse Act protected their right to possession and that a 1795 land cession lacked United States consent. They sought damages for fair rental value for 1968–1969. Lower federal courts dismissed for lack of a federal question.

Reasoning

The key question was whether the tribes’ asserted right to possession came from federal law rather than state law. The Court held the complaint did allege a present federal right to possession grounded in treaties and federal statutes, not merely a possible defense. Citing long‑standing doctrine that tribal occupancy and treaty protections are governed by federal law, the Court found jurisdiction under the federal civil‑question statute and under the statute allowing tribes to sue without an amount‑in‑controversy limit, reversed the Court of Appeals, and sent the case back for further federal proceedings.

Real world impact

The ruling means the Oneida tribes may pursue this land claim in federal court and that counties and state officials defending current possession will face federal litigation based on treaties and the Nonintercourse Acts. The decision is about jurisdiction, not the final merits, so the tribes may still lose on the facts or law later.

Dissents or concurrances

A concurrence stressed agreement with the result but warned the decision does not loosen federal courts’ traditional reluctance to hear ordinary ejectment suits; the narrow rules for routine land claims remain intact.
