Note on use: Oliphant is a negative precedent for tribes — it stripped tribal courts of inherent criminal jurisdiction over non-Indians. ATN includes it because every modern tribal court argument has to navigate around it. Knowing exactly what Oliphant says (and what it does NOT say) is essential to understanding why VAWA 2013/2022, the Lara framework, and Lexington v. Smith all matter.
Background & Facts
Mark Oliphant, a non-Indian residing on the Port Madison Reservation, was arrested by Suquamish tribal police during a tribal celebration for assaulting a tribal officer and resisting arrest. A second non-Indian defendant, Daniel Belgarde, was charged with reckless endangerment after a high-speed chase ended in a collision with a tribal police vehicle.
Both men were charged in Suquamish Tribal Court under the tribe's criminal code. They challenged the tribal court's jurisdiction, arguing that an Indian tribe has no inherent power to try and punish non-Indians.
The Ninth Circuit upheld tribal jurisdiction. The Supreme Court reversed.
The Court's Holding
Justice Rehnquist held, 6-2, that Indian tribes do not have inherent criminal jurisdiction to try and punish non-Indians, and may not assume such jurisdiction unless Congress specifically authorizes it. The Court reasoned that tribes had implicitly given up criminal jurisdiction over non-Indians by their "dependent status" within the United States.
Key Holding (and Its Limits):
Tribes lack inherent criminal jurisdiction over non-Indians. But the Court expressly preserved Congress's power to restore that jurisdiction by statute. The holding is about the source of authority, not its ceiling — Congress can give back what Oliphant said the tribes had lost. VAWA 2013 and 2022 did exactly that.
Key Language
"Indian tribes do not have inherent jurisdiction to try and to punish non-Indians."
"Indian tribes are prohibited from exercising both those powers of autonomous states that are expressly terminated by Congress and those powers 'inconsistent with their status.'"
Justice Marshall, dissenting: "I agree with the court below that the 'power to preserve order on the reservation... is a sine qua non of the sovereignty that the Suquamish originally possessed.' In the absence of affirmative withdrawal by treaty or statute, I am of the view that Indian tribes enjoy as a necessary aspect of their retained sovereignty the right to try and punish all persons who commit offenses against tribal law within the reservation."
Why ATN Cares About Oliphant
Oliphant is a wound that Congress has been suturing ever since. For ATN, the decision matters in three ways — and each one points toward action, not surrender.
- 1. Oliphant is criminal-only. The decision says nothing about civil jurisdiction. Tribes retain inherent civil regulatory and adjudicatory authority over non-Indians under the Montana framework — see Montana v. United States and Lexington v. Smith. ATN's tribal court can hear civil cases against nonmember businesses, contractors, and parties to consensual relationships today.
- 2. Congress can override Oliphant. VAWA 2013 restored Special Domestic Violence Criminal Jurisdiction (SDVCJ); VAWA 2022 expanded it into Special Tribal Criminal Jurisdiction (STCJ) covering sexual violence, stalking, child violence, sex trafficking, obstruction, and assault on tribal officers. ATN can opt into STCJ and exercise criminal jurisdiction over non-Indians for these offenses without amending the Constitution.
- 3. Oliphant's reasoning is contested. Justice Marshall's dissent — joined by the Chief Justice — articulates the position ATN's broader sovereignty arguments embrace: that the power to preserve order on the reservation is a sine qua non of sovereignty, not a power tribes implicitly waived. Modern scholars and several sitting Justices (notably Gorsuch in McGirt) treat Oliphant skeptically. The decision is good law, but its foundation is shakier every year.
For PL280 specifically: Oliphant is often misread as evidence that tribal courts are weak. The opposite is true. Oliphant addressed only one narrow question (criminal jurisdiction over non-Indians) and explicitly preserved tribal sovereignty in every other dimension. PL280 added a layer of state criminal jurisdiction; Oliphant did not subtract anything from tribal authority over members or from tribal civil jurisdiction. The space ATN's tribal court can occupy under current law is much larger than the post-Oliphant rhetoric suggests.
