The Statutory Text (Current)
"No purchase, grant, lease, or other conveyance of lands, or of any title or claim thereto, from any Indian nation or tribe of Indians, shall be of any validity in law or equity, unless the same be made by treaty or convention entered into pursuant to the Constitution."
In plain English: no one can buy, lease, or take Indian land without federal approval. Any transfer made without congressional authorization is void — not voidable, but void. This has been federal law since George Washington signed the first Trade and Intercourse Act in 1790.
How the Nonintercourse Act Works
Voids Unauthorized Transfers
Any state, county, corporation, or individual that purchased or took Indian land without federal treaty or statutory authorization holds void title. The land was never legally transferred. This is the basis for all eastern Indian land claims (Oneida I, Oneida II, Mashpee, Passamaquoddy).
No Statute of Limitations
Oneida II (1985) held that there is no federal statute of limitations for Nonintercourse Act claims. The void transfer remains void regardless of how much time has passed — though Sherrill (2005) later imposed equitable defenses (laches, acquiescence) on certain remedies.
Federal Question Jurisdiction
Oneida I (1974) held that claims under the Nonintercourse Act present a federal question — giving tribes access to federal courts for land claims.
How This Protects ATN's Mendocino Reservation
- 1. Mendocino Reservation land is federally protected. Any historical transfer of Mendocino Indian Reservation land that occurred without federal authorization is void under the Nonintercourse Act — regardless of how long ago it happened.
- 2. California's unratified treaties. The 18 treaties of 1851-52 were never ratified — meaning the land cessions they contemplated never took legal effect. Any California land taken from tribes outside those (non-existent) treaty cessions may violate the Nonintercourse Act.
- 3. Foundation for land-back claims. If ATN can identify parcels of the original Mendocino Indian Reservation that were transferred without proper federal authorization, the Nonintercourse Act voids those transfers.
- 4. Trust land is doubly protected. Land held in trust by the United States for ATN cannot be alienated without congressional authorization — the Nonintercourse Act plus trust law create overlapping protections.
- 5. Oldest active federal Indian law. The Nonintercourse Act has been continuously in effect for 236 years. It predates the Constitution's ratification by states, making it among the very first laws of the United States.
