In Oliphant v. Suquamish Indian Tribe, 435 U.S. 191 (1978), the U.S. Supreme Court ruled 6–2 that Indian tribal courts have no inherent criminal jurisdiction over non-Indians and cannot prosecute them unless Congress specifically grants that power. The decision pushed criminal cases against non-Indian defendants on reservation land into the federal and state court systems, and it remains the default rule today despite narrow congressional carve-outs for certain violent offenses.1Justia. Oliphant v. Suquamish Indian Tribe, 435 US 191 (1978)
How the Case Reached the Supreme Court
The dispute grew out of two arrests during the Chief Seattle Days celebration on the Port Madison Reservation in Washington State. Tribal police arrested Mark David Oliphant, charging him with assaulting a tribal officer and resisting arrest. In a separate incident, Daniel B. Belgarde led tribal police on a high-speed chase that ended when he crashed into a patrol car; he was charged with reckless endangerment and damaging tribal property.
Both men were non-Indians, and both were scheduled for trial before the Suquamish Indian Provisional Court. Under the Indian Civil Rights Act of 1968, the tribal court could impose no more than six months in jail or a $500 fine.2Office of the Law Revision Counsel. 25 USC 1302 – Constitutional Rights Rather than answer the charges, they filed habeas corpus petitions in federal court under 28 U.S.C. § 2241, arguing the tribe had no authority to try them at all.3Office of the Law Revision Counsel. 28 USC 2241 – Power To Grant Writ The federal district court agreed with the two men. The Ninth Circuit reversed and upheld the tribe’s jurisdiction. The Supreme Court then took the case.1Justia. Oliphant v. Suquamish Indian Tribe, 435 US 191 (1978)
What the Court Held
Justice William Rehnquist wrote for the majority. The holding was direct: Indian tribal courts do not have inherent criminal jurisdiction to try and punish non-Indians, and they cannot assume that authority unless Congress affirmatively delegates it.1Justia. Oliphant v. Suquamish Indian Tribe, 435 US 191 (1978) The rule applied to every reservation and every criminal charge involving a non-Indian defendant.
The practical consequence was immediate. A tribal officer could still detain a non-Indian caught committing a crime on reservation land, but the tribe had to hand the case off to federal or state prosecutors. Anything those outside authorities declined to pursue would go unprosecuted.
The Court’s Reasoning
The majority grounded the decision in a doctrine it called implicit divestiture. Tribes retain sovereignty, the Court said, but by coming under the protection of the United States they surrendered certain sovereign powers by implication, even without a treaty or statute expressly taking those powers away. Criminal jurisdiction over non-Indians was one of them.
Rehnquist walked through early treaties, congressional enactments, and executive branch statements that, in the majority’s reading, assumed non-Indians on tribal land would answer only to federal or state law. The opinion pointed to the Treaty of Point Elliott, signed by the Suquamish, as evidence that the tribe had recognized the overriding sovereignty of the United States.1Justia. Oliphant v. Suquamish Indian Tribe, 435 US 191 (1978) Tribes, described as “domestic dependent nations,” could govern their own members but could not exercise criminal authority over U.S. citizens outside the tribe. The majority also flagged concern that non-Indians tried in tribal court might not receive the full protections of the Bill of Rights.
That framing was itself a shift. The traditional presumption in federal Indian law had been that tribes retain all sovereign powers not explicitly stripped away by Congress. For criminal jurisdiction over non-Indians, the Court reversed the presumption.
The Dissent
Justice Thurgood Marshall dissented, joined by Chief Justice Warren Burger. Justice William Brennan took no part in the case.1Justia. Oliphant v. Suquamish Indian Tribe, 435 US 191 (1978) Marshall argued that the power to keep order within its own territory is a basic attribute of any sovereign, and that unless Congress specifically takes that power from a tribe, it remains with the tribe. In his view, implicit divestiture invented a limitation the precedents did not support and left reservation communities without a way to hold outside offenders accountable.
Who Prosecutes Crimes on Reservations After Oliphant
Because tribal courts lost the ability to prosecute non-Indians, jurisdiction over reservation crime now depends on who the defendant is, who the victim is, and whether Congress has given the state a role.
The General Crimes Act
The General Crimes Act, 18 U.S.C. § 1152, extends most federal criminal laws into Indian country and is the main vehicle for prosecuting non-Indians who commit crimes against Indian victims on reservations.4Office of the Law Revision Counsel. 18 USC 1152 – Laws Governing Crimes between two non-Indians on tribal land generally fall to the state. Crimes between two Indians go to the tribe, or to federal court for serious offenses.
The Major Crimes Act
Under the Major Crimes Act, 18 U.S.C. § 1153, federal courts have jurisdiction when an Indian commits any of roughly a dozen serious offenses in Indian country, including murder, kidnapping, arson, burglary, robbery, and several sexual offenses. The victim may be Indian or non-Indian.5Office of the Law Revision Counsel. 18 USC 1153 – Offenses Committed Within Indian Country
Public Law 280
Congress transferred most criminal jurisdiction over Indian country to state courts in six states: Alaska, California, Minnesota, Nebraska, Oregon, and Wisconsin. Other states later assumed partial jurisdiction.6Bureau of Indian Affairs. What Is Public Law 280 and Where Does It Apply Washington was not among the mandatory Public Law 280 states, which is part of why the Suquamish jurisdictional dispute reached the Supreme Court.
The Prosecution Gap
In practice, cases involving non-Indian offenders often stall. Tribal police can arrest, but the file goes to federal prosecutors who may be hundreds of miles away and working through crowded dockets. A Government Accountability Office review found that from 2005 to 2009, U.S. Attorneys declined 50 percent of all Indian country criminal referrals. For violent crimes, the declination rate was 52 percent. For sexual abuse cases, 67 percent were declined.7Government Accountability Office. US Department of Justice Declinations of Indian Country Criminal Matters When federal prosecutors pass, the tribe cannot step in, so many of those cases end without any prosecution at all. That outcome is the most criticized legacy of the decision.
What Congress Has Changed Since 1978
Congress has narrowed Oliphant’s reach in two ways, though the core holding is still in place.
The Duro Fix
In Duro v. Reina, 495 U.S. 676 (1990), the Supreme Court extended Oliphant’s logic to hold that tribes also lack criminal jurisdiction over Indians who are members of a different tribe.8Justia. Duro v. Reina, 495 US 676 (1990) Congress reversed that result within months, amending the Indian Civil Rights Act to recognize and affirm the inherent power of tribes “to exercise criminal jurisdiction over all Indians.”9Office of the Law Revision Counsel. 25 USC 1301 – Definitions The Supreme Court upheld the fix in United States v. Lara (2004).10Legal Information Institute. United States v. Lara The Duro fix did nothing for non-Indian defendants.
VAWA 2013 and 2022
The first congressional reversal of Oliphant for non-Indian defendants came in the Violence Against Women Reauthorization Act of 2013, which recognized tribal “special domestic violence criminal jurisdiction” over non-Indians for domestic violence, dating violence, and violations of protection orders.11U.S. Department of Justice. 2013 and 2022 Reauthorizations of the Violence Against Women Act (VAWA) The 2022 reauthorization broadened the list to nine categories of covered crimes: domestic violence, dating violence, sexual violence, stalking, child violence, sex trafficking, assault of tribal justice personnel, obstruction of justice, and violations of protection orders.
For most of these offenses, the victim must be Indian. Two exceptions — obstruction of justice and assault of tribal justice personnel — allow prosecution even when both defendant and victim are non-Indian. Participation is voluntary, and participating tribes must give defendants the right to counsel, a law-trained judge, and a jury drawn from a fair cross section of the community that includes non-Indians.12Office of the Law Revision Counsel. 25 USC 1304 – Tribal Jurisdiction Over Covered Crimes Drug offenses, property crimes, and most other offenses by non-Indians on reservations remain outside tribal criminal authority.
Civil Cases Are Governed by a Different Rule
Oliphant addressed criminal jurisdiction only. Tribal authority over non-Indians in civil matters runs on a separate framework set by Montana v. United States, 450 U.S. 544 (1981). Under Montana, tribes generally lack civil authority over non-members on non-Indian-owned land within a reservation, with two exceptions: non-Indians who enter consensual relationships with the tribe through commercial dealings, contracts, or leases, and non-Indian conduct that directly threatens the political integrity, economic security, or health and welfare of the tribe.13Justia. Montana v. United States, 450 US 544 (1981) So a non-Indian who cannot be criminally prosecuted in tribal court may still face tribal regulatory enforcement, contract claims, or civil penalties in some circumstances.
Where the Rule Stands Today
Nearly five decades on, Oliphant is still the starting point for any question about criminal jurisdiction over non-Indians on tribal land. Congress has cut back its reach for nonmember Indians through the Duro fix and for specific violent offenses through the VAWA reauthorizations, but each expansion has required tribes to adopt procedural protections that go beyond what the Constitution demands of state courts. Outside those categories, the rule the Court announced in 1978 controls: without an act of Congress, a tribe cannot criminally prosecute a non-Indian, and the case belongs to federal or state authorities or to no one at all.
