Conner Lee Polk appeals his four-year prison sentence under the Assimilative
Crimes Act (ACA), 18 U.S.C. § 13, for committing a state-law offense on an Indian Appellate Case: 22-5037 Document: 010110825224 Date Filed: 03/13/2023 Page: 2
reservation in Oklahoma. Polk argues that the district court should have considered
imposing a shorter prison term under an Oklahoma statute that permits a departure
from a mandatory minimum sentence in certain circumstances. Because this state law
conflicts with federal sentencing policy, the district court properly declined to apply
it, and we affirm Polk’s sentence.
Background
In December 2019, Polk crashed his pickup truck into two cars while
intoxicated, seriously injuring occupants in one of the vehicles. Because this conduct
occurred on an Indian reservation and Polk is an Indian, a federal prosecution ensued
under the ACA. As explained in more detail later, the ACA applies to acts committed
on an Indian reservation that are crimes in the state within which the reservation is
located—here, Oklahoma—but are not otherwise crimes under federal law. See
§ 13(a). The government charged Polk under the ACA with an Oklahoma DUI
offense that carries a mandatory prison sentence of at least 4 years and at most 20
years. See Okla. Stat. tit. 47, § 11-904(B)(1). He eventually pleaded guilty to that
offense.1
Despite the mandatory minimum applicable to his offense, Polk at sentencing
requested a prison term of less than four years. For support, he cited Oklahoma’s
“safety-valve” law, which allows state-court judges in certain circumstances to
1 Polk also pleaded guilty to an ACA offense for involvement in an accident that damaged a vehicle, see Okla. Stat. tit. 47, § 10-103, for which he received a concurrent six-month prison sentence. He does not challenge his conviction or sentence for this offense. 2 Appellate Case: 22-5037 Document: 010110825224 Date Filed: 03/13/2023 Page: 3
impose a sentence below a statutory mandatory minimum. See Okla. Stat. tit. 22,
§ 985.1(A). The district court, however, concluded that it could not apply
Oklahoma’s safety-valve law because that provision conflicts with federal sentencing
provisions that permit federal courts to depart from statutory mandatory minimums
only in two limited circumstances, neither of which exists here. See 18 U.S.C.
§ 3553(e)–(f). Given this conflict, the district court sentenced Polk to the four-year
mandatory minimum prison term.
Analysis
Polk appeals his sentence, arguing that the district court erred in declining to
apply Oklahoma’s safety-valve law to consider whether he qualified for a departure
below the four-year mandatory minimum. That argument hinges on whether the
district court properly interpreted the ACA, the relevant federal sentencing
provisions, and Oklahoma’s safety-valve law. We review those legal determinations
de novo. See United States v. Chapman, 839 F.3d 1232, 1241 (10th Cir. 2016).
As relevant here, the ACA provides federal jurisdiction over certain criminal
acts committed on Indian reservations.2 United States v. Garcia, 893 F.2d 250, 253
2 By its terms, the ACA applies only to crimes committed on federal enclaves—“areas where states have ceded jurisdiction over land within their borders to Congress, such as military bases, federal facilities, and national parks and forests.” United States v. Harris, 10 F.4th 1005, 1010 (10th Cir. 2021). It applies to crimes on Indian reservations by way of 18 U.S.C. § 1152, which extends federal-enclave law to Indian country, see United States v. Langford, 641 F.3d 1195, 1197 (10th Cir. 2011) (explaining that “in conjunction,” ACA and § 1152 “(1) assimilate state criminal law into federal law” for acts committed on federal enclaves and “(2) apply these assimilated state crimes to acts committed in Indian country”). 3 Appellate Case: 22-5037 Document: 010110825224 Date Filed: 03/13/2023 Page: 4
(10th Cir. 1989). When such acts occur, they are often prohibited by specific federal
criminal statutes. For instance, the Major Crimes Act, 18 U.S.C. § 1153(a),
proscribes a list of severe offenses, such as murder and kidnapping, that are federal
crimes when committed by Indians in Indian country. But sometimes, as is the case
here, no particular federal statute covers the defendant’s conduct, meaning it would
not otherwise be a federal crime. United States v. Jones, 921 F.3d 932, 935 (10th Cir.
2019). In that event, the ACA steps in and generates a federal offense using the laws
of the state in which the relevant reservation is located. See id. More precisely, it
allows federal courts to “borrow [the relevant crime] from preexisting state law,”
thereby creating an applicable federal offense to fill the gap in the U.S. Code. United
States v. Christie, 717 F.3d 1156, 1170 (10th Cir. 2013); cf. also United States v.
Martinez, 1 F.4th 788, 790 (10th Cir. 2021) (explaining that “[t]he assimilated state
offense becomes a federal offense punishable under federal law”), cert. denied, 142
S. Ct. 1373 (2022).
Notably, however, the ACA does not require federal courts to incorporate
every aspect of state criminal law that may apply to the newly created offense. See
Christie, 717 F.3d at 1171–72. To the contrary, it requires only that they ensure the

S. Ct. 1373 (2022).
Notably, however, the ACA does not require federal courts to incorporate
every aspect of state criminal law that may apply to the newly created offense. See
Christie, 717 F.3d at 1171–72. To the contrary, it requires only that they ensure the
defendant receives a “like punishment,” § 13(a)—one similar to the punishment he or
she would receive in state court. See Christie, 717 F.3d at 1171–72 (emphasizing that
“the ACA requires like punishment, not precisely the same punishment”). Typically,
this like-punishment standard means that we must apply “any maximum and
minimum prison terms pr[e]scribed by state law for an assimilated crime.” Id. at
4 Appellate Case: 22-5037 Document: 010110825224 Date Filed: 03/13/2023 Page: 5
1171. But in imposing a sentence between those mandatory values, federal courts
need not “duplicate every last nuance of the sentence that would be imposed in state
court.” Id. at 1172 (quoting Garcia, 893 F.2d at 254). And critically, “federal courts
must depart from state [sentencing laws] when Congress has expressed a specific and
contrary penal policy.” Id.; see also United States v. Wood, 386 F.3d 961, 963 (10th
Cir. 2004) (“[W]hen sentencing defendants for assimilated crimes, federal courts
have consistently declined to assimilate state sentencing laws if such laws conflict
with the [United States Sentencing] Guidelines and their underlying policies.”).
Applying this principle, the district court concluded that it could not sentence
Polk under the Oklahoma safety-valve law because that law conflicts with federal
sentencing policy, in particular 18 U.S.C. § 3553(e) and (f). Polk disputes this
conclusion, arguing that no such conflict exists and that the district court therefore
should have incorporated Oklahoma’s safety-valve law and considered imposing a
prison term of less than four years.
But Polk does not meaningfully grapple with the district court’s reasons for
finding a conflict. As the district court explained, under § 3553, federal sentencing
judges may “depart from a mandatory minimum sentence only in [two] enumerated,
limited circumstances,” neither of which applies here.3 App. vol. 1, 41; see also
United States v. C.D., 848 F.3d 1286, 1292 & n.5 (10th Cir. 2017) (noting that
3 As the district court also noted, the Guidelines similarly permit such departures only in the two circumstances outlined in § 3553(e) and (f). See U.S.S.G. §§ 5C1.2, 5K1.1. 5 Appellate Case: 22-5037 Document: 010110825224 Date Filed: 03/13/2023 Page: 6
§ 3553 contains the “only two congressionally-authorized exceptions to a mandatory
minimum sentence” (emphasis added)). Specifically, they may do so only when the
defendant (1) provides substantial assistance to a criminal investigation or
prosecution, or (2) is convicted of certain listed drug offenses and satisfies five
statutory factors. § 3553(e)–(f). Oklahoma’s safety-valve law, on the other hand,
allows departures from mandatory minimums under a broader set of circumstances.
See Okla. Stat. tit. 22, § 985.1(A) (permitting departure for certain qualifying
offenses when mandatory minimum “is not necessary for the protection of the
public,” “would result in substantial injustice to the defendant,” or “is not necessary
for the protection of the public and the defendant . . . has been accepted” to
alternative court, diversion program, or community sentencing). Thus, as the district
court concluded, Oklahoma’s safety-valve law conflicts with federal sentencing
policy because it would allow a prison term below the mandatory minimum in
circumstances other than those exclusively provided for in § 3553(e) and (f).4
Polk’s contrary argument does not undermine this straightforward textual
conclusion. He suggests that the district court erred by basing its conclusion that a
conflict exists on a determination that the federal safety-valve provision, § 3553(f),
4 This direct tension between what state law permits and what federal law forbids answers Polk’s assertion, drawn from an analogy to the conflict-preemption doctrine, that two laws do not conflict if they merely “overlap” and that a conflict instead requires that it be “[im]possible to comply with both” laws. Rep. Br. 6 (quoting Kansas v. Garcia, 140 S. Ct. 791, 806 (2020)). This impossibility standard plainly is met here: Both provisions cannot be given effect because, as mentioned above, Oklahoma’s safety-valve law allows departures for reasons that would not support a departure under § 3553(e) and (f). 6 Appellate Case: 22-5037 Document: 010110825224 Date Filed: 03/13/2023 Page: 7
“never references” the ACA specifically. Aplt. Br. 25–26. From that premise, Polk
then argues that no language in § 3553(f) shows that Congress intended “to exclude
[the ACA] from [federal] safety[-]valve consideration.” Rep. Br. 3. But this argument
both misunderstands and fails to refute the district court’s conflict analysis. As
explained, the district court did not base its conclusion that Oklahoma’s safety-valve
law conflicts with § 3553 on Congress’s failure to mention the ACA in subsection (f)
(or subsection (e), for that matter).5 Instead, it based that conclusion on the fact that
Oklahoma’s safety-valve law would allow departures below the mandatory minimum
in circumstances beyond those provided for in § 3553(e) and (f). Nothing about
Polk’s § 3553(f) argument disputes this unambiguous conflict, and this conflict is
fatal to Polk’s sentencing challenge.6 See Christie, 717 F.3d at 1172.
Conclusion
In sum, because Oklahoma’s safety-valve law conflicts with federal sentencing
5 To the extent that this failure to mention the ACA in the federal safety-valve provision has any significance, it suggests that Congress did intend to exclude ACA offenses because § 3553(f) specifies that it applies only “in the case of” certain enumerated drug offenses. See Navajo Nation v. Dalley, 896 F.3d 1196, 1213 (10th Cir. 2018) (“[T]he enumeration of certain things in a statute suggests that the legislature had no intent of including things not listed or embraced” (quoting Seneca-Cayuga Tribe of Okla. v. Nat’l Indian Gaming Comm’n, 327 F.3d 1019, 1034 & n.24 (10th Cir. 2003))). 6 Because the relevant statutory language is unambiguous, we do not address Polk’s arguments about legislative history, statutory purpose, and the rule of lenity supporting his position. See In re Geneva Steel Co., 281 F.3d 1173, 1178 (10th Cir. 2002) (noting that courts must interpret an unambiguous statute “according to its plain meaning,” considering legislative history and statutory purpose only “[i]f a statute is ambiguous”); United States v. Black, 773 F.3d 1113, 1117 (10th Cir. 2014) (requiring showing of “grievous ambiguity or uncertainty in the statute” to apply rule of lenity (quoting Dean v. United States, 556 U.S. 568, 577 (2009))). 7 Appellate Case: 22-5037 Document: 010110825224 Date Filed: 03/13/2023 Page: 8
policy—specifically, § 3553(e) and (f)—the district court did not err in declining to
apply that state law when sentencing Polk. Instead, the district court properly
incorporated only the state-law mandatory minimum applicable to Polk’s crime,
thereby providing him with the “like punishment” the ACA requires. § 13(a). Thus,
we affirm Polk’s sentence.
