Background & Facts
Samuel Worcester was a Christian missionary living among the Cherokee Nation in what was then claimed by Georgia as the territory of Cherokee Country. Georgia had enacted a series of laws purporting to extend state authority over Cherokee lands and requiring all non-Indians residing in Cherokee Country to obtain a license from the state and swear an oath of allegiance.
Worcester refused. He was arrested, convicted of violating Georgia's licensing law, and sentenced to four years of hard labor. He appealed to the United States Supreme Court, arguing that Georgia had no authority to extend state law into Cherokee Country in the first place.
The case was decided in the shadow of President Andrew Jackson's removal policy and is the second of the "Marshall Trilogy" (after Cherokee Nation v. Georgia, 1831). It is the most consequential statement of tribal sovereignty in U.S. constitutional history.
The Court's Holding
Chief Justice Marshall, writing for the Court, held that Georgia had no authority whatsoever to extend its laws into Cherokee Country. The Cherokee Nation was a "distinct community" with sovereign authority over its own territory, recognized by federal treaties, and the laws of Georgia "can have no force" within Cherokee borders. Worcester's conviction was reversed.
Key Holding:
Indian nations are "distinct, independent political communities, retaining their original natural rights." States have NO inherent jurisdiction over Indian Country. Any state authority over tribal land must come from federal law and tribal consent — not from the state's own initiative. Worcester is the constitutional bedrock of federal Indian law.
Key Language
"The Cherokee nation, then, is a distinct community, occupying its own territory, with boundaries accurately described, in which the laws of Georgia can have no force, and which the citizens of Georgia have no right to enter, but with the assent of the Cherokees themselves, or in conformity with treaties, and with the acts of congress."
"The whole intercourse between the United States and this nation, is, by our constitution and laws, vested in the government of the United States."
"Indian nations had always been considered as distinct, independent political communities, retaining their original natural rights, as the undisputed possessors of the soil, from time immemorial."
How Worcester Defeats P.L. 280
Worcester is the answer to every state-jurisdiction argument California has ever made. States possess zero inherent authority over Indian Country. Whatever authority California exercises — under P.L. 280 or otherwise — must come from a valid federal grant, and that federal grant must be measured against the foundational principle Marshall established 193 years ago.
The structural argument:
- 1. Worcester establishes that states have NO inherent jurisdiction over tribal land.
- 2. Any state authority must come from a federal grant.
- 3. That federal grant must be express, narrow, and consistent with tribal sovereignty.
- 4. P.L. 280 was enacted without tribal consent — violating the consent principle Marshall expressly identified ("with the assent of the Cherokees themselves").
- 5. A federal statute that violates the foundational structural principle of federal Indian law cannot validly extend state authority into Indian Country.
Worcester is also the explicit textual source for the consent principle. Marshall did not merely say states cannot enter Indian Country — he said they cannot enter "but with the assent of the Cherokees themselves, or in conformity with treaties." Consent is in the foundational language of federal Indian law itself. P.L. 280 had neither tribal assent nor treaty conformity. Under Worcester's own words, it cannot stand.
