592 F.2d 575 (1st Cir. 1979)
The case of Mashpee Tribe v. New Seabury Corp.
Whether the Mashpee Tribe qualified as a 'tribe' under federal law, thus invoking protections of the Non-Intercourse Act for their land claims.
A group must demonstrate that it has been a distinct, continuous community with political authority from historical times to qualify as an Indian tribe under federal law.
The court held that the Mashpee Tribe did not qualify as a continuous tribal entity under federal law and consequently, could not invoke the protections of the Indian Non-Intercourse Act.
This case is a cornerstone for understanding the legal complexities around tribal recognition and historical land claims under American Indian law. It highlights the significant challenges inherent in proving uninterrupted tribal status, which is crucial for accessing certain legal protections. Law students must recognize the implications of evidentiary requirements in establishing historical and cultural continuity for tribes to assert and protect their legal rights.
