Background & Purpose
The Indian Reorganization Act of 1934 was a watershed in federal Indian policy — the "Indian New Deal." It reversed the catastrophic allotment policy of the Dawes Act (1887), which had broken up communal tribal lands into individual parcels, resulting in the loss of nearly 90 million acres of tribal land (two-thirds of the 1887 tribal land base).
Commissioner of Indian Affairs John Collier championed the IRA as a return to tribal self-governance and communal land ownership. The Act ended further allotment, authorized the Secretary of the Interior to acquire land in trust for tribes, and encouraged tribes to adopt constitutions and form business corporations.
The IRA fundamentally reshaped the federal-tribal relationship from one of forced assimilation to one of (at least partial) self-determination — though full self-determination policy would not arrive until ISDEAA in 1975.
Key Provisions
§ 5101 — End of Allotment
No more individual allotments. Surplus lands restored to tribal ownership. Existing trust periods on allotments extended indefinitely — preventing forced fee patents and subsequent land loss.
§ 5108 — Land into Trust (Section 5)
The Secretary of the Interior "is authorized... to acquire... any interest in lands... within or without existing reservations... for the purpose of providing land for Indians." This is the legal basis for trust land acquisitions — the provision at issue in Carcieri v. Salazar.
§ 5123 — Tribal Constitutions (Section 16)
Tribes may organize and adopt constitutions approved by the Secretary of the Interior. Constitutional tribes exercise "all powers vested in any Indian tribe or tribal council by existing law" plus powers granted by the constitution.
§ 5124 — Tribal Corporations (Section 17)
Tribes may incorporate under federal charters for business purposes. Section 17 corporations can own property, enter contracts, and conduct business — with sovereign immunity extending to the corporation as an arm of the tribe.
§ 5129 — Definition of "Indian" (Section 19)
Defines "Indian" for IRA purposes to include "members of any recognized Indian tribe now under Federal jurisdiction." This "now under Federal jurisdiction" language was interpreted in Carcieri v. Salazar (2009) to mean "in 1934."
How the IRA Supports ATN
The IRA is the statutory backbone of tribal governance and land protection.
- 1. Land-into-trust authority. Section 5 authorizes the Secretary to take land into trust for ATN. The Mendocino Indian Reservation was established in 1856 — well before 1934 — satisfying Carcieri's "under federal jurisdiction in 1934" requirement.
- 2. Tribal constitution and governance. Section 16 authorizes ATN to adopt a constitution exercising all powers of self-governance. ATN's Constitution (2025) operates under this framework.
- 3. Business corporations. Section 17 allows ATN to charter tribal corporations for cannabis licensing, economic development, and other business operations — with sovereign immunity protection.
- 4. Trust land protection. Section 5's trust status protects ATN land from state taxation (Mescalero v. Jones), state regulation (Cabazon), and adverse possession (Upper Skagit). Trust land is the foundation of ATN's sovereignty.
- 5. Tax exemption. Section 5 provides that trust land "shall be exempt from State and local taxation." This is the statutory basis for ATN's property tax exemption.
