18 USC 1153: Major Crimes Act Jurisdiction and Penalties

18 U.S.C. § 1153, known as the Major Crimes Act, gives federal courts jurisdiction over thirteen categories of serious crime when a Native American commits one of them in Indian Country. Enacted in 1885 and amended several times since, the statute pulls the most serious offenses out of tribal courts and into the federal system. Whether it applies to a given case depends on three variables: what crime happened, where it happened, and whether the person accused is legally recognized as Indian.

The Thirteen Offenses

The Major Crimes Act lists specific crimes, not broad categories. If an offense is not on the list, § 1153 does not reach it, though another federal statute sometimes will. The covered offenses are:

  • Murder (first and second degree) and manslaughter (voluntary and involuntary)
  • Kidnapping
  • Maiming
  • Felony sexual abuse under chapter 109A of title 18, which covers aggravated sexual abuse, sexual abuse, sexual abuse of a minor or ward, and abusive sexual contact1Office of the Law Revision Counsel. 18 USC 1153 – Offenses Committed Within Indian Country
  • Incest
  • Felony assault under 18 U.S.C. § 113, including assault with a dangerous weapon and assault resulting in serious bodily injury
  • Assault against a child under 16
  • Felony child abuse or neglect
  • Arson
  • Burglary
  • Robbery
  • Felony theft of property worth more than $1,000, or theft from another person’s body regardless of value2Office of the Law Revision Counsel. 18 USC 661 – Within Special Maritime and Territorial Jurisdiction

Drug trafficking is a common assumption that turns out to be wrong. It is not an MCA offense. Drug crimes in Indian Country are charged under the Controlled Substances Act. Sexual exploitation of children (chapter 110 of title 18) also sits outside the MCA. The charging statute matters because the jurisdictional rules change with it.

The MCA does not create its own penalty scheme. Defendants face “the same law and penalties as all other persons” who commit those offenses within federal jurisdiction.

What Counts as Indian Country

Section 1153 only reaches conduct in “Indian country” as defined by 18 U.S.C. § 1151. Three categories of land qualify:

  • All land within the boundaries of any federally recognized reservation, including rights-of-way such as highways that pass through
  • Dependent Indian communities: areas set aside for Indian use under federal supervision without being formally designated as reservations
  • Indian allotments still held in trust or restricted status for an Indian owner3Office of the Law Revision Counsel. 18 USC 1151 – Indian Country Defined

Whether a particular tract fits one of these categories is often contested. The Supreme Court’s 2020 decision in McGirt v. Oklahoma confirmed that the Muscogee (Creek) Nation’s reservation had never been disestablished, and Oklahoma courts extended the same reasoning to at least nine additional tribal nations. That single ruling reshaped the jurisdictional map across much of eastern Oklahoma.

Who Qualifies as “Indian”

Section 1153 applies when “any Indian” commits a listed offense, but Congress never defined the term in the statute itself. Courts have built a two-part test: the person must have some degree of Indian blood, and they must be enrolled in or recognized as a member by a federally recognized tribe or the federal government.4United States Department of Justice Archives. Criminal Resource Manual 686 – Who Is An Indian Neither factor alone suffices. Someone with Indian ancestry and no tribal affiliation would not trigger MCA jurisdiction, and someone adopted into a tribe without any Indian blood generally would not either.

This threshold shows up in federal MCA cases more often than a casual reader might expect. Defense attorneys routinely challenge Indian status as a jurisdictional issue, and a successful challenge collapses the federal case. The Department of Justice defines “Indian” for these purposes as someone “enrolled or recognized as an Indian by a federally recognized tribe or the federal government and possessing some degree of Indian blood.”5Department of Justice.

How Jurisdiction Sorts Out

Criminal jurisdiction in Indian Country depends on the identities of the offender and the victim. The MCA is one piece of a layered system that also includes the General Crimes Act (18 U.S.C. § 1152), tribal law, and, in some places, state law.

Indian Offender, Indian Victim

Federal courts have jurisdiction over the listed MCA offenses. The tribe retains authority to prosecute any offense under tribal law, though tribal courts face sentencing caps that make federal prosecution the only realistic path to serious prison time for major crimes. States generally have no jurisdiction here.

Indian Offender, Non-Indian Victim

The MCA provides federal jurisdiction over the listed offenses. For crimes not on the list, the General Crimes Act may supply federal jurisdiction. After the Supreme Court’s 2022 decision in Oklahoma v. Castro-Huerta, states may also exercise concurrent jurisdiction in some circumstances.5Department of Justice. Indian Country Criminal Jurisdictional Chart

Non-Indian Offender, Indian Victim

The Major Crimes Act does not apply, because the offender is not Indian. Federal jurisdiction runs through the General Crimes Act instead. Tribal courts could not prosecute non-Indians at all after the Supreme Court’s 1978 ruling in Oliphant v. Suquamish Indian Tribe.6Library of Congress. Oliphant v. Suquamish Indian Tribe, 435 US 191 (1978) Congress partially reversed that bar in 2013 and expanded tribal authority further in 2022, letting tribes prosecute non-Indians for domestic violence, sexual violence, stalking, and several other offenses.7U.S. Department of Justice. 2013 and 2022 Reauthorizations of the Violence Against Women Act (VAWA)

Public Law 280 States

In 1953, Congress transferred criminal jurisdiction over much of Indian Country from the federal government to certain state governments. Six states were required to accept this jurisdiction, and others could opt in. In those states, the Major Crimes Act does not apply, and the state prosecutes what would otherwise be a federal case.8United States Department of Justice. Concurrent Tribal Authority Under Public Law 83-280 Identical crimes on different reservations can end up prosecuted by entirely different sovereigns depending on geography.

How McGirt and Castro-Huerta Changed the Picture

Two recent Supreme Court decisions redrew the jurisdictional map more dramatically than any legislation in decades.

In McGirt v. Oklahoma (2020), the Court held that the Muscogee (Creek) Nation’s reservation in eastern Oklahoma had never been disestablished by Congress. It remained Indian country for MCA purposes.9Justia Law. McGirt v. Oklahoma, 591 US (2020) Serious crimes committed by or against Indians across a large portion of eastern Oklahoma suddenly moved from state to federal jurisdiction. Oklahoma courts extended the reasoning to the Cherokee, Choctaw, Chickasaw, Seminole, and other nations.

Two years later, Oklahoma v. Castro-Huerta (2022) pulled some of that authority back toward the states. In a 5-4 decision, the Court held that states have concurrent jurisdiction to prosecute crimes committed by non-Indians against Indians in Indian Country, unless federal law specifically preempts state authority.10Justia Law. Oklahoma v. Castro-Huerta, 597 US (2022) Justice Kavanaugh’s majority opinion set a new default: states have criminal jurisdiction in Indian country unless it is preempted, reversing the longstanding assumption that states were excluded absent congressional invitation.

The combined effect is a landscape where more land counts as Indian country (expanding federal MCA reach) while states simultaneously have broader authority over non-Indian offenders. How this plays out on the ground varies by state and by working relationships among federal, state, and tribal prosecutors.

Penalties Under the MCA

Because § 1153 borrows the underlying federal penalty for each listed offense, the punishments are the same ones that apply anywhere federal criminal law reaches. For the most commonly prosecuted MCA offenses:

These penalties dwarf what tribal courts can impose. Under the Indian Civil Rights Act, tribal courts are generally limited to one year of imprisonment per offense. Tribes that meet enhanced sentencing requirements under the Tribal Law and Order Act can impose up to three years per offense and fines up to $15,000, but only if the tribe provides a licensed defense attorney to indigent defendants, uses a law-trained judge, publishes its criminal code, and maintains a record of proceedings.16Bureau of Justice Assistance. Tribal Law and Order Act Enhanced Sentencing Authority Quick Reference Checklist

Tribal Prosecution Alongside Federal Charges

A defendant prosecuted in tribal court can still be prosecuted in federal court for the same conduct without triggering double jeopardy. The Supreme Court affirmed this in United States v. Lara, holding that because tribes are separate sovereigns exercising inherent authority, successive tribal and federal prosecutions are permissible under the dual sovereignty doctrine.17Legal Information Institute. United States v. Lara

So a tribal court might prosecute an assault under tribal law and impose a sentence within its statutory cap, and the U.S. Attorney’s Office could then bring a separate federal case for the same assault under § 1153 with much steeper penalties. Tribal convictions generally do not count toward a defendant’s criminal history score under the federal sentencing guidelines, though a judge may consider them when deciding whether to depart upward from the advisory range.18U.S. Sentencing Commission. Report of the Tribal Issues Advisory Group

The Gap Between the Statute and Actual Prosecution

Section 1153 on paper reads like a straightforward federal takeover of serious crime in Indian Country. In practice, federal prosecutors decline to bring charges in a large share of cases referred to them. A Government Accountability Office review found that U.S. Attorney’s Offices declined roughly half of all Indian Country matters referred between 2005 and 2009. The declination rate for violent crimes was 52 percent. For sexual abuse cases, it reached 67 percent.19Government Accountability Office. GAO-11-167R – US Department of Justice Declinations of Indian Country Criminal Matters

The most common reasons were insufficient evidence (42 percent of declinations), no federal offense evident (18 percent), and witness problems (12 percent). When federal prosecutors decline, the tribe can still prosecute under tribal law, but with sentencing capped at one to three years, the practical result for serious violent crime is often a fraction of what federal law would allow. This gap is one of the driving forces behind legislative efforts to expand tribal court authority.

Statute of Limitations

For most offenses charged under § 1153, the government must indict within five years.20Office of the Law Revision Counsel. 18 US Code 3282 – Offenses Not Capital Murder has no time limit because it is a capital offense.21GovInfo. 18 USC 3281 – Capital Offenses For sexual abuse offenses under chapter 109A where the suspect’s identity is unknown, the government can file an indictment identifying the suspect by DNA profile, and the five-year clock does not start until the person is arrested or served.
