United States v. Kagama
The Court upheld a federal law making it a crime for one Indian to murder another Indian on a reservation inside a state, ruling that Congress had the constitutional power to pass it even though the Constitution never explicitly grants that authority.
The decision established that Congress has broad, largely unchecked power over Indian tribes because of their dependent and vulnerable status, a principle that would shape federal Indian law for generations.
How it got here: The trial judges of the federal Circuit Court in California disagreed on the law's validity, so they certified the disputed legal questions directly to the Supreme Court.
The Case in Depth
What happened
Two Indians, Kagama and Mahawaha, were indicted for murdering another Indian, Iyouse, on the Hoopa Valley Reservation in California. All three were members of the same tribe. The prosecution relied on a newly passed 1885 federal law criminalizing murder and other serious crimes committed by one Indian against another on a reservation within a state.
The question before the Court
Could Congress make it a federal crime for one Indian to murder another Indian on a reservation located entirely inside a state?
Why it matters
The ruling let the federal government, rather than the states, prosecute serious crimes committed by Indians against other Indians on reservations, a framework that still underlies federal criminal jurisdiction in Indian country today. It also cemented the idea that Congress holds sweeping authority over tribes as dependent wards rather than fully sovereign nations or ordinary citizens.
What changes now
The Court's answers to the certified questions resolve the legal dispute over the statute's validity, allowing the murder prosecution against Kagama and Mahawaha to proceed in the federal Circuit Court for the District of California. The ruling does not itself decide guilt or innocence; it simply confirms that the federal court has jurisdiction to try the case under the 1885 law.
What this does not decide
The opinion does not hold that Indian tribes are fully sovereign or fully subject to state law generally; it addresses only Congress's power to punish specific crimes among Indians on reservations within a state, leaving state authority over non-Indians and other tribal matters untouched.
How the Court got there
The legal reasoning, step by step
- The Court first asked whether any clause of the Constitution expressly gives Congress power to create a criminal code for Indians, and concluded that neither the apportionment clause nor the Indian Commerce Clause was written for that purpose, since regulating trade with tribes is not the same as punishing murder.
- Rather than finding an express textual grant, the Court reasoned that sovereignty over the entire geographic territory of the United States rests either with the federal government or the states, and Indian tribes occupy reservations within that territory without themselves being states or foreign nations.
- The Court described tribes as dependent, largely powerless communities that receive no protection from the states in which they live and are often treated with hostility by neighboring residents, which it treated as the source of a federal duty of protection.
- From that duty of protection the Court derived a corresponding federal power: because only the national government could practically enforce order and protect tribes across all reservations, the power to do so necessarily belonged to Congress alone.
- Applying this reasoning to the statute, the Court found the law only reached crimes among Indians on a reservation, left state courts' authority over non-Indians undisturbed, and therefore fit within the scope of federal authority over dependent tribes.
- The Court concluded that both branches of the 1885 statute — covering territories and covering reservations within states — were valid, and that the federal Circuit Court in California had jurisdiction over the murder charge.
