18 USC 1152: The General Crimes Act in Indian Country

18 U.S.C. 1152, known as the General Crimes Act, extends most federal criminal laws into Indian Country whenever a crime crosses the line between Native and non-Native people. It is the statute that lets a U.S. Attorney charge a non-Indian who commits a crime against an Indian on tribal land, and it is also the statute that keeps the federal government out of purely Indian-on-Indian matters. The rule is narrow in some places and surprisingly broad in others, and getting the categories right decides which courthouse a case lands in.

What 18 U.S.C. 1152 Does

The statute takes the body of federal criminal law that applies to places under exclusive federal jurisdiction, such as military bases and national parks, and applies that same law inside Indian Country.¹ Those federal enclave statutes cover murder, manslaughter, assault, arson, theft, sexual offenses, and receiving stolen property, among others.²

It also pulls in the Assimilative Crimes Act, 18 U.S.C. 13, which fills gaps by borrowing state criminal statutes. If someone commits an act in Indian Country that violates state law but no specific federal statute reaches it, the Assimilative Crimes Act converts it into a federal offense punishable under the law of the state where the Indian Country sits.² Between the enclave statutes and the borrowed state offenses, federal prosecutors have a wide toolkit under 1152.

Who and Where It Applies

Two questions decide whether 1152 governs a case: is the crime in Indian Country, and what are the Indian statuses of the defendant and the victim?

Indian Country is defined at 18 U.S.C. 1151 as three categories of land: all land within an Indian reservation under federal jurisdiction, including rights-of-way running through it; all dependent Indian communities within U.S. borders; and all Indian allotments whose titles have not been extinguished.³ That reaches further than most people expect. Trust allotments and dependent communities scattered across a state qualify, and the Supreme Court’s 2020 decision in McGirt v. Oklahoma confirmed that a reservation Congress never formally disestablished remains Indian Country even when the surrounding state has long treated it otherwise.⁴ It also does not reach as far as some assume. Under Alaska v. Native Village of Venetie Tribal Government (1998), a dependent Indian community must have been set aside by the federal government for use by Indians and remain under federal superintendence, so land a tribe simply purchased on the open market does not automatically qualify.⁵

Once the location fits, the statute’s practical reach is best understood by defendant and victim:

Non-Indian defendant, Indian victim: the classic 1152 case.
Indian defendant, non-Indian victim: covered by 1152 for offenses not on the Major Crimes Act list.
Indian defendant, Indian victim: excluded from 1152 by the statute itself.
Non-Indian defendant, non-Indian victim: excluded by United States v. McBratney (1882), which held that states have exclusive jurisdiction over non-Indian-on-non-Indian crimes in Indian Country.⁶

The Three Exceptions Written Into the Statute

Section 1152 lists three situations where it does not apply, and each has real consequences.

The first is offenses committed by one Indian against another Indian’s person or property. Congress removed those from 1152 and left them to tribal courts or, for the specific felonies enumerated in the Major Crimes Act, to federal prosecution under a different statute.¹

The second is prior tribal punishment. If a tribal member has already been punished under tribal law for the same offense, the federal government cannot pursue the case under 1152. This is a statutory bar in the text of the law, not a constitutional double jeopardy protection. That distinction matters, because dual sovereignty ordinarily allows a tribe and the federal government to prosecute the same person for the same conduct. Under 1152, Congress chose to block that possibility when tribal punishment came first.¹

The third is treaty-based exclusive tribal jurisdiction. Where a treaty gives a tribe exclusive jurisdiction over specific offenses, 1152 steps aside. Few treaties still contain such provisions, but the exception remains on the books.¹

How It Differs From the Major Crimes Act

Section 1152 works alongside 18 U.S.C. 1153, the Major Crimes Act, and the two are routinely confused. The Major Crimes Act targets Indian defendants who commit any of a specific list of serious felonies in Indian Country, regardless of whether the victim is Indian or non-Indian. Its enumerated offenses include murder, manslaughter, kidnapping, maiming, certain sexual offenses, incest, felony assault, assault on a child under 16, felony child abuse or neglect, arson, burglary, robbery, and felony theft.⁷

The rough sorting rule: if the defendant is Indian and the crime is on the Major Crimes Act list, jurisdiction runs through 1153. If the defendant is non-Indian, or if the crime is not on that list, 1152 is the more likely vehicle. An Indian defendant who commits a non-enumerated offense against a non-Indian can still be prosecuted under 1152, because the Indian-on-Indian exclusion is not in play. The two statutes overlap at the edges, which is part of why jurisdictional fights in Indian Country never quite settle.

Proving Someone Is “Indian”

Because jurisdiction under 1152 turns on the Indian status of the defendant and the victim, that status is a fact the prosecution must prove. Federal courts generally require the government to establish two elements beyond a reasonable doubt: that the person has some degree of Indian blood, and that the person was a member of, or affiliated with, a federally recognized tribe at the time of the offense.⁸

Enrollment in a federally recognized tribe is strong evidence but not the only route. Courts have found individuals to be Indian for jurisdictional purposes based on social and cultural ties to a tribe, even without formal enrollment. Distant Indian ancestry with no tribal connection, on the other hand, is not enough. A failure to prove Indian status can undo an entire prosecution.

Where States Fit In

The old baseline, from Worcester v. Georgia (1832), was that state law had no force on tribal lands.⁹ Two things have changed that picture.

Congress created the first big exception in 1953 with Public Law 280, which required six states to assume criminal jurisdiction over Indian Country within their borders: Alaska, California, Minnesota (except Red Lake Reservation), Nebraska, Oregon (except Warm Springs Reservation), and Wisconsin. Several other states later opted into full or partial jurisdiction.¹⁰ In those states, many crimes that would otherwise be federal under 1152 are prosecuted by state courts instead.

The Supreme Court then reshaped the map again in Oklahoma v. Castro-Huerta (2022), holding that states have concurrent jurisdiction with the federal government to prosecute crimes committed by non-Indians against Indians in Indian Country.¹¹ The majority framed state criminal jurisdiction in Indian Country as the default unless Congress has preempted it. That was a sharp departure from the prior understanding that federal jurisdiction over the core 1152 scenario was exclusive outside Public Law 280 states.

The practical upshot is that in the most common 1152 case, a non-Indian defendant charged with a crime against an Indian victim, the local U.S. Attorney and the state district attorney may both have authority. Which office actually brings charges often comes down to resources, the severity of the offense, and the working relationship between federal and state law enforcement in that area.

Investigation, Prosecution, and Declination

When a case triggers 1152, the FBI is the principal investigating agency for serious offenses, working with the Bureau of Indian Affairs Office of Justice Services.¹² Tribal police often make the initial response, but cases headed to U.S. District Court are handled by federal agents and prosecuted by the U.S. Attorney’s Office for the judicial district covering that Indian Country. Defendants receive the standard federal criminal protections: grand jury indictment, right to counsel, and jury trial.

Declination is a persistent issue. In 2021, the U.S. Attorney declination rate for Indian Country matters was roughly 18 percent, with insufficient evidence cited in 56 percent of declinations.¹³ When a U.S. Attorney declines to prosecute, federal law requires coordination with tribal justice officials so that evidence can be used in tribal court if the tribe has jurisdiction. The U.S. Attorney must also report declination data annually, including offense types, the Indian or non-Indian status of the accused and victim, and the reasons for declining.¹⁴

The statute of limitations is the ordinary federal one. Under 18 U.S.C. 3282, non-capital offenses must be charged within five years of the commission of the crime, not from discovery or reporting. Capital offenses have no time limit.

Penalties and Restitution

A conviction under 1152 is a federal conviction, and sentencing runs through the U.S. Sentencing Guidelines. Judges weigh the offense conduct, the defendant’s criminal history, and any aggravating or mitigating circumstances, with discretion to vary from the guideline range. Penalties can include federal prison, supervised release, and fines. Because federal ranges are typically much longer than what a tribal court could impose for comparable conduct, a defendant prosecuted federally under 1152 often faces a sentence several times what a tribal proceeding could produce for the same underlying acts.

Restitution is mandatory in cases involving crimes of violence and property offenses with an identifiable victim who suffered physical injury or financial loss. The order can cover medical expenses, lost income, funeral costs in death cases, and the value of damaged or destroyed property, as well as costs of participating in the investigation and prosecution such as transportation and childcare.¹⁵ Where an offense qualifies, the judge has no discretion to skip it.
