4. Analysis of the Principal Precedents and Legal Reasoning
A. Why the court partially overruled Prentiss II
The three decisions captioned United States v. Prentiss explain both the former rule and the limits of its displacement.
-
Prentiss I, 206 F.3d 960 (10th Cir. 2000): The panel treated the defendant’s and victim’s Indian or non-Indian statuses as essential allegations in an indictment charging arson under § 1152.
-
Prentiss II, 256 F.3d 971: Judge Henry’s majority opinion treated both statuses as elements. A different majority, writing through Judge Baldock, held that omitting those allegations did not eliminate subject-matter jurisdiction and was subject to harmless-error review.
-
Prentiss III, 273 F.3d 1277: The panel subsequently found the indictment’s omissions not harmless and vacated the conviction.
The current court rejects the first of Prentiss II’s relevant propositions, but only as applied to a defendant’s status in a prosecution involving an Indian victim. Its treatment of subject-matter jurisdiction, by contrast, is consistent with Judge Baldock’s earlier majority.
Judge Henry’s reasoning had emphasized the importance of status to the practical reach of federal criminal law and the feasibility of requiring prosecutors to allege it. The present opinion considers that approach insufficiently attentive to the statute’s structure: a generally applicable first paragraph followed by separately stated exceptions.
The court also addresses adherence to precedent. Relying on Pearson v. Callahan, 555 U.S. 223 (2009), it explains that stare decisis is not absolute and that reliance interests are relatively weak for procedural and evidentiary rules that do not organize lawful private conduct. Later Supreme Court decisions, particularly Dixon v. United States and Cunningham v. Cornell University, supplied the doctrinal reason for reconsideration.
B. Statutory exceptions: the controlling relationship between McKelvey v. United States and United States v. Cook
McKelvey v. United States, 260 U.S. 353 (1922), provides the central interpretive rule: an indictment founded on a general statutory provision ordinarily need not negate an exception stated in a separate proviso or clause. A person relying on the exception must raise and establish it.
The court treats this as a longstanding rule, not a recent innovation. United States v. Dickson, 40 U.S. (15 Pet.) 141 (1841), described the principle as an established maxim of statutory interpretation, and Dixon v. United States, 548 U.S. 1 (2006), reaffirmed it.
The qualification comes from United States v. Cook, 84 U.S. (17 Wall.) 168 (1872). Some exceptions are so integrated into an offense’s definition that the offense cannot accurately and clearly be described without them. Such exceptions must be addressed in the charging allegations.
Prentiss II had applied that qualification to the intra-Indian exception. The present court concludes that this was mistaken. Section 1152’s first paragraph remains intelligible without the second: it extends federal enclave criminal law to Indian country. The intra-Indian exception limits that general rule but is not necessary to describe it.
Cunningham v. Cornell University, 604 U.S. 693 (2025), is especially important. It reaffirmed that statutory exceptions ordinarily create affirmative defenses and explained that the United States v. Cook qualification has been applied narrowly, including where the exception appears in the same sentence defining the offense. The Tenth Circuit reads this clarification as undermining Prentiss II’s broader approach.
The analysis is not simply that paragraph placement mechanically decides every case. Rather, textual separation supports a substantive conclusion: Congress articulated a complete general rule before specifying circumstances in which it does not apply.
United States v. Carey, 929 F.3d 1092 (9th Cir. 2019), supplies additional support for treating a separable exception as a defense. The defendants’ reliance on Nicoli v. Briggs, 83 F.2d 375 (10th Cir. 1936), did not establish that this method applies only to statutes independently defining every substantive ingredient of a crime.
C. Why § 1152’s incorporation of other offenses does not change the result
Ruiz argued that § 1152 does not itself define a substantive crime and therefore falls outside the ordinary rule for statutory exceptions. The court rejects that distinction.
Although § 1152 operates alongside substantive criminal statutes, it still adds a necessary geographic requirement: the offense must occur in Indian country. Nothing in the cited authorities makes the general exceptions rule unavailable merely because a statute extends other criminal laws rather than restating them.
The defense position also encountered an internal difficulty. It characterized § 1152 as incapable of defining offense elements while simultaneously insisting that the statute made non-Indian status an essential element. The court instead treats the provision as establishing both a general extension of federal law and separately stated limits on that extension.
D. Historical victim-status decisions do not decide the defendant-status question
Prentiss II had relied heavily on Lucas v. United States, 163 U.S. 612 (1896), and Famous Smith v. United States, 151 U.S. 50 (1894). The present opinion substantially narrows their relevance.
Lucas v. United States. The earlier opinion understood this case to require proof of the victim’s status rather than a presumption based on race. The current court emphasizes that it concerned the Act of May 2, 1890, not § 1152 or its statutory predecessors. It therefore cannot directly settle the construction of § 1152.
Famous Smith v. United States. This case concerned whether the evidence established that the deceased was an Indian. Its description of an instruction placing proof of the victim’s non-Indian status on the government was not an endorsement of that instruction: the Supreme Court expressly declined to decide the correctness of the legal propositions in the charge.
More fundamentally, neither decision resolved who must produce evidence or bear persuasion concerning the defendant’s Indian status in the circumstances now presented. The present court refuses to turn language about a victim into a universal rule covering every participant’s status.
The opinion also rejects reliance on a Supreme Court syllabus as though it were part of the Court’s holding. A reporter’s summary cannot override qualifications in the judicial opinion itself. Its reference to Sparf v. United States, 156 U.S. 51 (1895), illustrates the limited subsequent treatment of Famous Smith v. United States, rather than supplying an independent doctrinal basis.
Other authorities previously supporting status allegations included Hilderbrand v. United States, 261 F.2d 354 (9th Cir. 1958), and United States v. Torres, 733 F.2d 449 (7th Cir. 1984). Their treatment of indictments and proof does not overcome the present opinion’s narrower analysis of the defendant’s intra-Indian affirmative defense.
Importantly, the court does not decide the separate victim-status issue addressed in United States v. Reza-Ramos, 816 F.3d 1110 (9th Cir. 2016). Its criticism of historical reasoning should not be mistaken for a comprehensive holding eliminating victim-status requirements.
E. Sovereign authority and constitutional jurisdictional elements
The defendants maintained that diversity of Indian status was necessary to connect the prosecution to Congress’s constitutional authority. The court rejects this analogy to an interstate-commerce element.
United States v. Lopez, 514 U.S. 549 (1995), explains why a case-specific jurisdictional element can ensure that criminalized conduct falls within an enumerated federal power. United States v. Chavarria, 140 F.4th 1257 (10th Cir. 2025), and United States v. Patton, 451 F.3d 615 (10th Cir. 2006), similarly discuss a federal “jurisdictional hook.”
But the relevant hook here is Indian country. United States v. Jackson, 82 F.4th 943 (10th Cir. 2023), and United States v. Tony, 637 F.3d 1153 (10th Cir. 2011), recognize that geographic requirement as a jurisdictional element. Torres v. Lynch, 578 U.S. 452 (2016), supplies the broader explanation that such elements connect offenses to Congress’s constitutional powers.
The court relies on United States v. Antelope, 430 U.S. 641 (1977), for Congress’s authority to prescribe criminal law applicable in Indian country. Haaland v. Brackeen, 599 U.S. 255 (2023), and United States v. Lara, 541 U.S. 193 (2004), reinforce the breadth of congressional authority over Indian affairs.
United States v. Kagama, 118 U.S. 375 (1886), is especially damaging to the defendants’ argument because it upheld the Major Crimes Act, which permits prosecution of specified Indian-on-Indian crimes. Congress therefore possesses authority to reach conduct that § 1152’s intra-Indian exception excludes. The exception reflects Congress’s statutory allocation of authority, not a constitutional prohibition on federal prosecution.
On this reasoning, constitutional avoidance does not require a different interpretation. The court likewise rejects the defendants’ invocation of the lenity principle associated with Rewis v. United States, 401 U.S. 808 (1971), because the asserted uncertainty about congressional power does not exist.
F. Subject-matter jurisdiction is different from statutory coverage
Hebert separately argued that the absence of diverse status deprived the district court of subject-matter jurisdiction. The opinion’s answer is categorical: federal criminal adjudicatory jurisdiction comes from § 3231.
United States v. Tony, quoting United States v. White Horse, 316 F.3d 769 (8th Cir. 2003), anchors this distinction. United States v. Martin, 147 F.3d 529 (7th Cir. 1998), had similarly informed the jurisdictional portion of Prentiss II. Failure to establish a necessary component of criminal liability ordinarily defeats the prosecution on the merits; it does not mean the court lacked power to adjudicate it.
Historical Indian-law decisions sometimes used “jurisdiction” more expansively. The court explains that older terminology cannot automatically establish a modern subject-matter limitation. It relies on:
-
United States v. Cotton, 535 U.S. 625 (2002), and Steel Co. v. Citizens for a Better Env't, 523 U.S. 83 (1998), distinguishing adjudicatory authority from older, broader uses of jurisdictional language;
-
Ex parte Bain, 121 U.S. 1 (1887), as part of the historical explanation for expansive jurisdictional terminology when Supreme Court review of criminal judgments was restricted;
-
Santos-Zacaria v. Garland, 598 U.S. 411 (2023), Fort Bend County. v. Davis, 587 U.S. 541 (2019), Harrow v. Dep't of Def., 601 U.S. 480 (2024), and Arbaugh v. Y&H Corp., 546 U.S. 500 (2006), cautioning against treating every statutory limitation as jurisdictional.
Louie v. United States, 254 U.S. 548 (1921), provides a particularly close analogy. Whether a Major Crimes Act offense occurred in Indian country concerned the merits and the reach of federal law, not the convicting court’s adjudicatory jurisdiction.
Finally, Patchak v. Zinke, 583 U.S. 244 (2018), and Sebelius v. Auburn Reg'l Med. Ctr., 568 U.S. 145 (2013), underscore the importance of clear jurisdictional language. Section 1152’s exceptions lack the language ordinarily associated with withdrawing judicial authority.
G. The historical allocation of federal, state, and tribal authority
The court’s background discussion explains why practical sovereign authority and the statutory affirmative-defense question must remain distinct.
United States v. McBratney, 104 U.S. 621 (1882), and Draper v. United States, 164 U.S. 240 (1896), establish state authority over non-Indian-on-non-Indian crimes in Indian country. Donnelly v. United States, 228 U.S. 243 (1913), explains the effect of state admission on the former federal arrangement.
That judicially created exception is analytically different from § 1152’s express intra-Indian exception. As United States v. Haggerty, 997 F.3d 292 (5th Cir. 2021), observes, the practical importance of the United States v. McBratney rule does not make it part of § 1152’s statutory text. United States v. Walker, 85 F.4th 973 (10th Cir. 2023), describes the resulting cross-status operation of § 1152.
Oklahoma v. Castro-Huerta, 597 U.S. 629 (2022), adds that states and the federal government possess concurrent authority to prosecute non-Indians for crimes against Indians in Indian country. Its textual description of § 1152 as extending federal law, rather than creating an exclusively federal enclave, also supports the present court’s reading.
Ex parte Crow Dog, 109 U.S. 556 (1883), supplies the historical foundation for the intra-Indian exception. The subsequent Major Crimes Act is discussed through United States v. Brice, 167 F.4th 1330 (11th Cir. 2026), and United States v. Wadena, 152 F.3d 831 (8th Cir. 1998). United States v. Smith, 178 F.4th 572 (10th Cir. 2026), supports the account of the predecessor statutes, while United States v. Wheeler, 435 U.S. 313 (1978), supplies context concerning traditional tribal justice.
These historical sources explain the framework; they do not independently determine who bears the evidentiary burdens now in dispute.
H. Why the defendant also bears the burden of persuasion
The most consequential additional step is the court’s assignment of the ultimate burden of persuasion to the defendant. Classifying an issue as an affirmative defense does not, by itself, answer every burden question. The court therefore separately examines the governing default and constitutional limits.
Dixon v. United States and Smith v. United States, 568 U.S. 106 (2013), provide its principal authorities. Where Congress has not specified otherwise, the common-law allocation generally places proof of an affirmative defense on the defendant.
The constitutional limitation is essential: the government cannot shift to the defendant the burden of disproving an element of the crime. Patterson v. New York, 432 U.S. 197 (1977), United States v. Unser, 165 F.3d 755 (10th Cir. 1999), and United States v. Lofton, 776 F.2d 918 (10th Cir. 1985), inform that distinction.
Here, the court reasons that proving Indian status establishes a statutory exemption; it does not negate the substantive sexual-abuse elements or the fact that the conduct occurred in Indian country. Thus, the constitutional requirement that the prosecution prove offense elements beyond a reasonable doubt does not require it to disprove this defense.
The court also cites Justice Alito’s concurrence in Ruan v. United States, 597 U.S. 450 (2022), for the historical allocation. That proposition is identified as coming from a concurrence, not from the Court’s majority holding. United States v. Sturm, 672 F.3d 891 (10th Cir. 2012), confirms that genuine jurisdictional elements remain part of the government’s burden.
The defendants’ analogy to limitations defenses fails. Although Musacchio v. United States, 577 U.S. 237 (2016), recognizes a government burden when a limitations defense is properly raised, the court finds no reason to extend that allocation to Indian status merely because both defenses restrict prosecution without denying the underlying conduct.
This reasoning depends on the earlier statutory interpretation. The court does not simply label Indian status a defense and stop; it first concludes that the exception is separable from the offense’s general definition, then applies the affirmative-defense burden rules.
I. The express disagreement with the Fifth and Ninth Circuits
United States v. Hester, 719 F.2d 1041 (9th Cir. 1983), and United States v. Haggerty agree with the Tenth Circuit that defendants initially must produce evidence of Indian status. They disagree about what follows: both retain an ultimate government burden.
The Tenth Circuit finds their persuasion analyses insufficient. It rejects the Fifth Circuit’s theory that Indian status affects the geographic jurisdictional element: an intra-Indian offense still occurred in Indian country, even if the statutory exception prevents prosecution under § 1152.
The opinion also traces United States v. Hester through United States v. Guess, 629 F.2d 573 (9th Cir. 1980), to Davis v. United States, 160 U.S. 469 (1895). Dixon v. United States subsequently explained that the insanity-related burden in Davis v. United States depended on the relevant statute’s heightened mental-state requirement and was not a universal constitutional rule for affirmative defenses.
The resulting disagreement is therefore precise: the circuits substantially agree on production but diverge on who loses when the evidence does not resolve Indian status sufficiently.
J. Informational asymmetry supports the allocation
The court supplements its doctrinal reasoning with comparative access to evidence. An individual ordinarily knows more than prosecutors about personal ancestry, tribal affiliations, benefits, and community ties.
Dixon v. United States, Smith v. United States, Selma, R. & D.R. Co. v. United States, 139 U.S. 560 (1891), and United States v. Hartsock, 347 F.3d 1 (1st Cir. 2003), support assigning proof to the party with peculiar knowledge of the relevant facts.
The vacated panel opinions illustrated the investigative difficulty. The government had relied on incomplete searches, limited personal knowledge, and evidence that did not reliably resolve the two-part status test. United States v. Erickson, 561 F.3d 1150 (10th Cir. 2009), had supplied the evidentiary framework used in the Hebert panel’s insufficiency analysis.
The new rule avoids requiring prosecutors to establish non-Indian status in every covered case. It does not, however, change what Indian status means. Nor does it suggest that the former rule invariably required disproving both ancestry and recognition: because both are necessary for Indian status, sufficiently disproving either would defeat it.
The initial production threshold remains relatively modest in principle. United States v. Brown, 128 F.4th 1358 (10th Cir. 2025), describes production on a recognized defense as generally “not onerous.” The opinion does not supply a detailed, case-specific formula for satisfying that threshold here.
K. The Indian canon does not control
Ramah Navajo Chapter v. Lujan, 112 F.3d 1455 (10th Cir. 1997), E.E.O.C. v. Cherokee Nation, 871 F.2d 937 (10th Cir. 1989), and Montana v. Blackfeet Tribe, 471 U.S. 759 (1985), articulate the principle that ambiguous federal statutes should be construed favorably to Indians.
The parties disagreed about what that principle favored. The government emphasized protection of Indian victims and community safety; the defendants emphasized tribal self-government and limitations on outside prosecution. Oneida County v. Oneida Indian Nation of N.Y. State, 470 U.S. 226 (1985), supplied the trust-relationship rationale.
The court declines to make the canon decisive for two reasons. First, it finds no ambiguity sufficient to activate it. Under South Carolina v. Catawba Indian Tribe, Inc., 476 U.S. 498 (1986), the canon cannot manufacture ambiguity or defeat clearly expressed congressional intent.
Second, even if applicable, the canon does not automatically favor an accused individual over victims or the tribe. Negonsott v. Samuels, 507 U.S. 99 (1993), drawing on Bryan v. Itasca County, 426 U.S. 373 (1976), rejects that automatic equivalence.
The opinion treats its change as procedural rather than a reallocation of substantive sovereign authority: the same statutory exception remains available, covering the same persons and conduct. Its treatment of the canon is therefore limited to this burden-allocation dispute, not a general rejection of Indian-law interpretive protections.
5. Vacatur, Retrial, and Constitutional Protections
A. Why double jeopardy does not bar further proceedings
The defendants invoked Burks v. United States, 437 U.S. 1 (1978), which prohibits retrial after an appellate determination that the evidence was legally insufficient. The Tenth Circuit distinguishes the procedural posture.
Granting en banc review vacated the panel judgments and stayed the mandates under the circuit’s local rule. The en banc opinion then expressly vacated the panel opinions. Accordingly, there was no operative appellate acquittal or surviving insufficiency determination. Both defendants had been convicted by juries, and their trial courts had denied acquittal motions.
This also distinguishes United States v. Scott, 437 U.S. 82 (1978), Evans v. Michigan, 568 U.S. 313 (2013), Arizona v. Rumsey, 467 U.S. 203 (1984), and United States v. Jenkins, 420 U.S. 358 (1975). The acquittals or absence of guilty verdicts material to those cases were not present here.
The narrow point is procedural finality, not a general license to retry defendants after acquittal. A vacated panel ruling in a still-pending direct appeal did not become an acquittal immune from en banc reconsideration.
B. Why retroactive application does not violate due process
The Ex Post Facto Clause directly constrains legislative action. Judicial changes in criminal law are instead subject to related, but less extensive, due-process limits.
Under United States v. Budder, 76 F.4th 1007 (10th Cir. 2023), and Rogers v. Tennessee, 532 U.S. 451 (2001), the inquiry concerns fair warning and whether a judicial construction is unexpected and indefensible by reference to prior law.
The court finds no violation because the decision changes proof allocation, not the conduct prohibited. Sexual abuse of children in Indian country was already criminal. The defendants’ legal status could affect the statutory route to prosecution, but not supply fair warning that the underlying conduct was lawful.
The court also relies on the preexisting inter-circuit disagreement and longstanding statutory-exception principles. United States v. Muskett, 970 F.3d 1233 (10th Cir. 2020), explains that a circuit split may provide notice of a potentially broader construction even where the defendant’s own circuit has adopted a narrower view.
C. Why retrial remains possible rather than mandatory
The records were developed under a rule that placed proof on the prosecution. Neither defendant had notice at trial that he was responsible for establishing Indian status as a defense. That procedural reality requires further consideration rather than an automatic final disposition.
The panels must also address unresolved claims:
- Hebert’s challenges concerning the definition of non-Indian status and the prosecution’s use of his silence about status;
- Ruiz’s vagueness challenge and objection to a modified Allen instruction.
The en banc court does not decide those claims. Depending on their resolution, the panels may return the cases to the district courts for decisions concerning retrial.
Exby-Stolley v. Bd. of Cnty. Comm'rs, 979 F.3d 784 (10th Cir. 2020), supports resolving a recurring legal issue to guide proceedings on remand. Kirkendall v. Dep't of Army, 479 F.3d 830 (Fed. Cir. 2007), and United States v. Padilla, 415 F.3d 211 (1st Cir. 2005), support the court’s consideration of the persuasion question expressly included in its en banc order.
The court’s procedural citations to Contreras-Bocanegra v. Holder, 678 F.3d 811 (10th Cir. 2012), United States v. Nacchio, 555 F.3d 1234 (10th Cir. 2009), and United States v. Perez, 989 F.2d 1574 (10th Cir. 1993), illustrate en banc authority to replace precedent and vacate panel rulings. They do not independently establish the substantive Indian-status rule.
