United States v. Brice: Generally Applicable Federal Criminal Statutes Apply to Indian-on-Indian Crimes in Indian Country, Unconstrained by the Major Crimes Act

I. Introduction

United States v. Sylvanis Brice (11th Cir. Feb. 27, 2026) consolidated the appeals of Uriah Waggerby, Sylvanis Brice, and Johan Holder after a jury trial in the Middle District of Florida. The prosecution arose from a planned robbery of Reuben Billie, Jr., a marijuana dealer, at his home on the Big Cypress Seminole Indian Reservation. During the attempted robbery, a bystander, Ronny Billie, Jr., was shot and killed, and the robbers fled without successfully stealing money or drugs.

The jury convicted:

  • Waggerby: conspiracy to commit Hobbs Act robbery (Count 1), acquitted on Counts 2 and 3.
  • Brice: conspiracy (Count 1) and attempted Hobbs Act robbery (Count 2), acquitted on Count 3.
  • Holder: conspiracy (Count 1) and attempted Hobbs Act robbery (Count 2), acquitted on Count 3.

Two issues dominated the appeal:

  1. Indian-country jurisdiction: whether federal courts have jurisdiction to prosecute an Indian for a generally applicable federal offense committed against another Indian in Indian country when the offense is not enumerated in the Major Crimes Act.
  2. Impeachment by prior convictions: whether the district court reversibly erred by admitting Brice’s prior convictions without conducting an on-the-record probative/prejudice balancing.

II. Summary of the Opinion

The Eleventh Circuit affirmed all convictions. It held that federal jurisdiction exists over crimes prosecuted under generally applicable federal criminal statutes (like the Hobbs Act), even when the defendant is Indian, the victim is Indian, and the conduct occurred in Indian country. The court also held the district court erred by failing to make an on-the-record balancing before admitting Brice’s prior convictions, but deemed the error harmless given the strength of the government’s evidence (including Brice’s recorded statements, corroborating ballistics, and cell-site/location evidence).

III. Analysis

A. Precedents Cited

1. The “patchwork” of Indian-country criminal jurisdiction

The court framed Indian-country jurisdiction as a “complex patchwork” by quoting Negonsott v. Samuels, 507 U.S. 99, 102 (1993). That framing matters: it justified the opinion’s careful sorting of federal statutes into categories (enclave statutes vs. generally applicable laws), instead of treating “Indian country” as a single jurisdictional switch that is either on or off for federal prosecutions.

2. Enclave statutes, the Indian Country Crimes Act, and the Major Crimes Act

The opinion used a line of cases about enclave-style statutes—where location is an element—to explain the role of the Indian Country Crimes Act and the Major Crimes Act.

  • United States v. Begay, 42 F.3d 486, 498 (9th Cir. 1994): cited for the definition of enclave statutes (situs as an element). This supported the opinion’s taxonomy: some federal criminal jurisdiction depends on where the conduct occurred.
  • United States v. Gaskell, 134 F.3d 1039, 1041 (11th Cir. 1998), and United States v. Pate, 321 F.3d 1373, 1374 (11th Cir. 2003): used to illustrate how the Assimilative Crimes Act operates (federal prosecution of state-law offenses on federal enclaves). These cases were not about Indian country directly; their function was conceptual, showing what it means for situs to be part of the crime’s structure.
  • Ex parte Crow Dog, 109 U.S. 556, 558–59 (1883), and United States v. Wadena, 152 F.3d 831, 840 (8th Cir. 1998): invoked to explain the historical impetus for the Major Crimes Act—Congress’s response to a jurisdictional gap perceived after Crow Dog.

Importantly, the panel treated Crow Dog as addressing the reach of enclave-linked federal law into Indian country (and the need for congressional clarity), not as a general restriction on all federal criminal statutes.

3. The key distinction: generally applicable federal statutes

The jurisdictional holding turned on a contrast between enclave statutes and federal laws that apply “to everyone, everywhere.” For that proposition, the court leaned on Supreme Court signals that general federal statutes include Indians unless Congress indicates otherwise:

  • Fed. Power Comm'n v. Tuscarora Indian Nation, 362 U.S. 99, 116 (1960): quoted for the proposition that “a general statute in terms applying to all persons includes Indians and their property interests.” This served as a doctrinal anchor for applying the Hobbs Act in Indian country without needing the Major Crimes Act.
  • United States v. Wheeler, 435 U.S. 313, 330 n.30, 331 n.31 (1978): cited for the Court’s recognition that federal jurisdiction extends to crimes “regardless of whether an Indian is involved” (e.g., assaulting a federal officer). The Eleventh Circuit treated this as strong confirmation that “generally applicable” federal crimes do not depend on the enclave/Indian-country jurisdictional machinery.

The panel also invoked its own Hobbs Act commerce precedent to reinforce that Hobbs Act robbery does not make location an element: United States v. Diaz, 248 F.3d 1065, 1084 (11th Cir. 2001).

4. Unanimous sister-circuit authority

Because the Eleventh Circuit had not previously decided the precise question, it relied heavily on uniform sister-circuit holdings that the Major Crimes Act does not limit prosecution under generally applicable federal criminal statutes:

  • United States v. Stone, 112 F.3d 971, 973 (8th Cir. 1997): general applicability where situs is not an element.
  • United States v. Top Sky, 547 F.2d 483, 484 (9th Cir. 1976): Major Crimes Act “has no bearing” on general laws criminalizing conduct wherever committed.
  • United States v. Boots, 80 F.3d 580, 593 (1st Cir. 1996), overruled in part on other grounds by Pasquantino v. United States, 544 U.S. 349, 354 (2005): cited as additional support for the general-statute rule (with careful note about partial overruling on other grounds).
  • United States v. Yannott, 42 F.3d 999, 1004 (6th Cir. 1994).
  • United States v. Barquin, 799 F.2d 619, 621 (10th Cir. 1986).

The Eleventh Circuit joined these circuits, effectively establishing binding circuit precedent on this jurisdictional point.

5. Addressing seemingly contrary Supreme Court language

Waggerby relied on passages suggesting that enumerating certain crimes implies exclusion of others. The court distinguished these as enclave/statute-specific rather than governing generally applicable federal criminal laws:

  • Ex parte Crow Dog, 109 U.S. at 572: “clear expression” language treated as directed to extending enclave-type laws and state criminal law into Indian country.
  • United States v. Quiver, 241 U.S. 602, 606 (1916): addressed a territorial statute (Edmunds-Tucker Act context), not a generally applicable federal statute.
  • United States v. Antelope, 430 U.S. 641, 643 n.2 (1977): described Major Crimes Act/enclave jurisdiction and tribal court jurisdiction, but the Eleventh Circuit read it as not speaking to “everyone, everywhere” statutes.

The court’s method was to confine these statements to the statutory domain they actually addressed (enclave-style federal criminal law and imported state law), leaving Wheeler and Tuscarora as the controlling guideposts for general statutes.

6. Tribal sovereignty and dual prosecutions

The court addressed Waggerby’s sovereignty concerns by analogizing to federal/state concurrent authority and federal/tribal concurrent authority:

  • Arizona v. United States, 567 U.S. 387, 416 (2012) (Scalia, J., concurring in part and dissenting in part), quoting Hinderlider v. La Plata River & Cherry Creek Ditch Co., 304 U.S. 92, 104 (1938): to emphasize the “indivisible Union” premise.
  • Heath v. Alabama, 474 U.S. 82, 87–89 (1985): cited for the proposition that separate sovereigns may prosecute the same act.
  • Denezpi v. United States, 596 U.S. 591, 598 (2022): invoked to show that tribal and federal prosecutions can coexist for the same conduct without negating sovereignty.

7. Evidentiary error: on-the-record balancing and harmlessness

On Brice’s prior convictions, the court treated the district court’s failure to balance on the record as legal error under binding precedent:

  • United States v. Pritchard, 973 F.2d 905, 908 (11th Cir. 1992): standard of review (abuse of discretion).
  • United States v. Preston, 608 F.2d 626, 639 (5th Cir. 1979): the key rule requiring “an on-the-record finding that the probative value ... outweighs its prejudicial effect,” and that the requirement “is not merely an idle gesture.” (Binding in the Eleventh Circuit via Bonner principles, though Bonner is not cited in the opinion.)
  • United States v. Augustin, 661 F.3d 1105, 1123 (11th Cir. 2011): harmless-error principle for evidentiary rulings.
  • United States v. Burston, 159 F.3d 1328, 1336 (11th Cir. 1998): error harmless if the government’s case is strong enough even apart from the challenged evidence.

8. Foreclosed issues (preserved but rejected)

The court noted additional arguments were conceded as foreclosed, and cited:

  • United States v. Isaacson, 752 F.3d 1291, 1300 (11th Cir. 2014): Speedy Trial Act waiver if no motion to dismiss.
  • United States v. Hano, 922 F.3d 1272, 1287 (11th Cir. 2019), and United States v. Underwood, 446 F.3d 1340, 1347 (11th Cir. 2006): Confrontation Clause applies to testimonial statements; admissions to a confidential informant are non-testimonial.

B. Legal Reasoning

1. The core holding: the Major Crimes Act is not a ceiling on federal jurisdiction

The opinion’s central move is structural: it treats the Major Crimes Act as an “exception to an exception” within a specific statutory framework, rather than as an exhaustive list defining the entire universe of federal criminal jurisdiction in Indian country.

The court reasoned as follows:

  1. The Indian Country Crimes Act extends to Indian country the “general laws ... as to the punishment of offenses committed” in the “sole and exclusive jurisdiction” of the United States—i.e., enclave-type laws—and then excludes Indian-on-Indian offenses.
  2. The Major Crimes Act then re-opens federal jurisdiction for Indian-on-Indian conduct for enumerated offenses that are themselves enclave/state-imported in character.
  3. Neither statute purports to limit the application of separate federal criminal statutes that apply “by their own terms” without making Indian country (or enclave situs) an element.
  4. Because the Hobbs Act is such a generally applicable statute—prohibiting robbery/extortion affecting commerce anywhere—its enforcement does not depend on the Major Crimes Act list.

This reasoning is reinforced by the court’s textual emphasis on the phrases “sole and exclusive jurisdiction” and “within the exclusive jurisdiction of the United States” in §§ 1152 and 1153, reading them as markers of enclave-type jurisdictional logic rather than general federal police power.

2. Limiting contrary dicta by subject matter

The court confronted language from Ex parte Crow Dog, United States v. Quiver, and United States v. Antelope that could be read to suggest that, absent Major Crimes Act enumeration, Indian-on-Indian crimes are exclusively tribal matters. The court limited those statements to their context: prosecutions premised on enclave statutes or territorial/state-imported law, not prosecutions under generally applicable federal statutes.

In effect, the Eleventh Circuit adopted a subject-matter partition: the “enumeration implies exclusion” logic may operate within the enclave-law extension framework, but it does not re-write separate federal criminal statutes that already apply nationwide.

3. Brice’s prior convictions: error identified, but harmlessness governs the remedy

On the evidentiary issue, the court applied a two-step approach:

  1. Error: Under United States v. Preston, the district court must make an on-the-record finding that the probative value outweighs prejudice before admitting prior conviction evidence (in this context, to impeach credibility). The district court did not do so.
  2. No reversal: Under United States v. Augustin and United States v. Burston, the error is harmless if the remaining evidence strongly supports conviction. The panel found the government’s case strong: Brice’s recorded “play-by-play” account, ballistics corroboration, and cell-site evidence placing him at the scene.

C. Impact

1. New (or clarified) Eleventh Circuit precedent on Indian-country prosecutions

The most significant contribution of United States v. Brice is its definitive adoption, for the Eleventh Circuit, of the sister-circuit consensus rule: federal courts have jurisdiction to prosecute violations of generally applicable federal criminal statutes committed by an Indian against an Indian in Indian country, and the Major Crimes Act does not limit that jurisdiction to its enumerated offenses.

Practically, this strengthens federal prosecutorial authority in Indian country for offenses such as Hobbs Act robbery, federal firearms crimes, federal drug crimes, and other commerce- or conduct-based statutes that do not make “Indian country” (or enclave situs) an element. Defendants can be expected to continue raising Major Crimes Act arguments as jurisdictional challenges; Brice largely closes that door in this circuit for generally applicable statutes.

2. Boundary maintenance: enclave framework remains relevant

The decision does not diminish the importance of the Major Crimes Act and Indian Country Crimes Act; rather, it confines their “gatekeeping” role to the enclave/state-imported category of prosecutions. Litigation will likely shift to classification disputes—i.e., whether a charged statute is truly “generally applicable” or instead contains a situs/jurisdiction element that triggers the enclave framework.

3. Trial practice: on-the-record balancing remains mandatory, but harmlessness is a real backstop

For evidentiary practice, the opinion reinforces that district courts must do the Preston balancing on the record when admitting prior convictions for impeachment. Yet it also demonstrates that appellate courts will often affirm where the government’s proof is otherwise overwhelming, reducing the likelihood of reversals solely for a missing on-the-record finding when the error does not plausibly affect the verdict.

IV. Complex Concepts Simplified

Indian country
A federal legal term (not fully defined in the opinion) generally referring to reservation land and certain other designated areas. Its status affects which sovereign(s)—federal, state, tribal—may prosecute certain crimes.
Enclave statutes
Federal criminal laws that depend on where the crime happens (the situs is an element), such as laws tied to “special maritime and territorial jurisdiction” or those that incorporate state law for federal enclaves (e.g., the Assimilative Crimes Act).
Indian Country Crimes Act (18 U.S.C. § 1152)
Extends enclave-type federal criminal law into Indian country but excludes Indian-on-Indian offenses (among other exceptions). It is about importing a jurisdictional regime, not about limiting all federal criminal statutes.
Major Crimes Act (18 U.S.C. § 1153)
Creates federal jurisdiction over a list of serious crimes committed by Indians in Indian country, including Indian-on-Indian cases, functioning as an exception to § 1152’s Indian-on-Indian exclusion. In Brice, it is not treated as an exhaustive list of all federal power in Indian country.
Generally applicable federal criminal statutes
Federal crimes written to apply nationwide to “anyone” without making the crime’s location (Indian country, enclave, etc.) an element. The Hobbs Act is such a statute because it focuses on affecting commerce, not on where the robbery occurs.
On-the-record balancing (probative value vs. prejudice)
A requirement that the trial judge explicitly state (or otherwise clearly show in the record) that the value of admitting prior convictions for credibility purposes outweighs the risk the jury will misuse them as “bad character” evidence. The Eleventh Circuit reaffirmed this requirement (via Preston) but held the failure was harmless on these facts.
Harmless error
An appellate doctrine under which a conviction stands despite a legal mistake if the reviewing court is confident the error did not affect the verdict, especially where the remaining evidence of guilt is strong.

V. Conclusion

United States v. Brice delivers a clear jurisdictional rule for the Eleventh Circuit: the Major Crimes Act does not restrict federal prosecution of generally applicable federal crimes committed by Indians against Indians in Indian country; such statutes apply of their own force. At the same time, the opinion reinforces procedural rigor in admitting prior convictions—requiring an on-the-record balancing—while illustrating that strong corroborated evidence can render the omission harmless on appeal. Together, these holdings expand clarity (and federal reach) in Indian-country criminal enforcement and sharpen trial-court obligations in credibility impeachment practice.
