I. INTRODUCTION
The defendant-appellant, Kalin Marie Campbell, appeals her sentence,
challenging the district court’s calculation of her Guidelines range. At issue are her
prior state convictions. Campbell argues those prior state convictions were entered by Appellate Case: 24-5086 Document: 56-1 Date Filed: 05/05/2026 Page: 2
courts lacking subject matter jurisdiction, thus rendering them void. She posits the
district court erred in considering these purportedly void state convictions when
calculating her Criminal History Category.
Campbell’s prior state convictions have not been vacated or reversed. Because
her state convictions were not obtained in violation of her right to counsel, she cannot
challenge the validity of those convictions in federal court during a sentencing
hearing for an unrelated federal offense. See Johnson v. United States, 544 U.S. 295,
303 (2005). When calculating a defendant’s Criminal History Category, sentencing
courts are to consider sentences from any outstanding prior conviction unrelated to
the instant offense. See U.S.S.G. §§ 4A1.1; 4A1.2 & cmt. 6. The district court did not
err by considering Campbell’s prior convictions when calculating her Criminal
History Category. Therefore, exercising jurisdiction pursuant to 18 U.S.C. § 3742(a)
and 28 U.S.C. § 1291, the court affirms the judgment of the district court.
II. BACKGROUND
Campbell is an enrolled member of the Osage Nation. Her criminal record
includes three convictions entered by various Oklahoma state courts. In 2013,
Campbell was charged in Washington County for driving a motor vehicle under the
influence. She pleaded guilty to multiple traffic-related charges and served 139 days
in state prison. Next, in June 2016, Campbell was convicted for possessing
methamphetamine and a loaded firearm while operating a vehicle in Mayes County.
She served a deferred sentence. Finally, in July 2016, Campbell was convicted in
Tulsa County of possession of a controlled substance and drug paraphernalia, as well

as false impersonation of another. For this third conviction, the state court imposed a
three-year sentence. Campbell was represented by counsel in the state criminal
proceedings leading to her convictions. The government does not contest that the
offenses underlying all three convictions were committed within Indian country as
defined in 18 U.S.C. § 1151. 1
In 2021, law enforcement began investigating a drug trafficking organization
distributing methamphetamine and heroin. Campbell was identified as one of the
organization’s main distributors in Tulsa. Upon a search of her home, agents from the
Drug Enforcement Administration discovered various quantities of controlled
substances as well as multiple firearms and ammunition. She was indicted in the
Northern District of Oklahoma on a single count of conspiring to distribute controlled
substances. See 21 U.S.C. §§ 841, 846. She pleaded guilty without entering into a
plea agreement.
In its presentence investigation report (“PSR”), the U.S. Probation Office
proposed an advisory Guidelines range of 360 months to life, reflecting its
underlying calculation of a total offense level at 42 and a Criminal History Category
of III. Campbell objected to the calculations set out in the PSR. She reasoned, inter
alia, none of her prior state convictions should be factored into the calculation of her
Criminal History Category because the relevant Oklahoma state courts lacked

jurisdiction over criminal conduct of tribal citizens committed on tribal land. During
the sentencing hearing, the district court overruled this objection, observing, in
particular, that the state convictions at issue remained outstanding because no
Oklahoma court had vacated them.
After resolving other objections not relevant to this appeal, the district court
concluded the total offense level was 34 and the Criminal History Category was III, 2
resulting in an advisory Guidelines range of 188 to 235 months. Campbell was
ultimately sentenced to 188 months of imprisonment, followed by five years of
supervised release. She timely appealed.
III. DISCUSSION
“A sentence must be both procedurally and substantively reasonable.” United
States v. Hanrahan, 508 F.3d 962, 969 (10th Cir. 2007). Campbell challenges the
procedural reasonableness of her sentence, arguing the district court erred in
calculating her Guidelines range. See id. (holding that a procedurally reasonable
sentence is one “calculated utilizing a legitimate method” (quotation omitted)).

guidelines de novo and its factual findings for clear error. United States v. Gantt, 679
F.3d 1240, 1246 (10th Cir. 2012).
In reviewing procedural reasonableness, the court “focuses on the manner in
which the sentence was calculated,” United States v. Sanchez-Leon, 764 F.3d 1248,
1261 (10th Cir. 2014), to “ensure that the district court committed no significant
procedural error, such as failing to calculate (or improperly calculating) the
Guidelines range,” Gall v. United States, 552 U.S. 38, 51 (2007). “Any error in the
Guidelines calculation renders a sentence procedurally unreasonable and, if the error
is not harmless, requires remand.” United States v. Conley, 89 F.4th 815, 820 (10th
Cir. 2023).
A defendant’s Criminal History Category is determined by attributing and
tallying points for their prior sentences. See U.S.S.G. § 4A1.1; see also id. ch. 5, pt.
A (setting out the sentencing table). The sentencing court is to consider “any sentence
previously imposed upon adjudication of guilt . . . for conduct not part of the instance
offense.” Id. § 4A1.2(a)(1). Excluded from consideration are sentences resulting from
convictions which have been “reversed or vacated” or “have been ruled
constitutionally invalid in a prior case.” Id. § 4A1.2 cmt. n.6; see United States v.
Maloid, 71 F.4th 795, 805 (10th Cir. 2023) (“[Guidelines commentary] governs
unless it runs afoul of the Constitution or a federal statute or is plainly erroneous or
inconsistent with the guideline provision it interprets.” (quotations omitted)). In this
5 Appellate Case: 24-5086 Document: 56-1 Date Filed: 05/05/2026 Page: 6
case, the district court attributed six points in total for Campbell’s three state
convictions, classifying her Criminal History Category as III. 3
Campbell contests this determination in three main steps. First, relying on
McGirt v. Oklahoma, 591 U.S. 894, 898 (2020), she claims Oklahoma state courts
generally lack subject matter jurisdiction over matters concerning conduct of Indian
persons committed in Indian country. Applying this proposition, Campbell asserts her
state convictions—having been entered by state courts for offenses she committed in
Indian country—are void. Second, she argues the validity of her state convictions
may be challenged during her federal sentencing hearing due to their purported
jurisdictional defects. Finally, Campbell concludes the district court committed
procedural error by factoring in these void state convictions when calculating her
Criminal History Category.
At the first step, the defendant makes an erroneous inferential leap. McGirt did
not, by itself, vacate or void existing state convictions. See 591 U.S. at 935 (“The
only question before us . . . concerns the statutory definition of ‘Indian country’ as it
applies in federal criminal law under the [Major Crimes Act].”). In fact, the Supreme
Court made clear that those who, based on McGirt, attempt to challenge existing state
convictions would be subject to the “well-known state and federal limitations on
postconviction review in criminal proceedings.” Id. at 933.
3 The district court adopted the presentence investigation report which attributed 1) two points for her conviction in 2013; 2) one point for her conviction in June 2016; and 3) three points for her conviction in July 2016.
6 Appellate Case: 24-5086 Document: 56-1 Date Filed: 05/05/2026 Page: 7
It has long been established in this court that “the issue of whether a court has
proper jurisdiction is a legal one and, hence, no conviction is ‘void from its
inception’ for lack of jurisdiction until a court with review authority has so declared.”
United States v. Mayfield, 810 F.2d 943, 946 (10th Cir. 1987). During the sentencing
hearing, Campbell explained it had not been “financially feasible” for her to contest
these prior convictions before the appropriate court. ROA Vol. III at 96.
Subsequently, the district court observed that Campbell’s state convictions had not
been reversed or vacated by any Oklahoma court. ROA Vol. III at 100. Thus,
regardless of the merits of her jurisdictional contentions, the court cannot conclude
Campbell’s prior state convictions have been rendered void.
Campbell’s argument at the second step also falls short. By challenging the
validity of her state convictions “in a proceeding other than a direct appeal,”
Campbell is raising a collateral attack. Wall v. Kholi, 562 U.S. 545, 552 (2011)
(italics omitted). In relevant part, the Guidelines commentary provides the following:
With respect to the current sentencing proceeding, this guideline and commentary do not confer upon the defendant any right to attack collaterally a prior conviction or sentence beyond any such rights otherwise recognized in law (e.g., 21 U.S.C. § 851 expressly provides that a defendant may collaterally attack certain prior convictions).
U.S.S.G. § 4A1.2 cmt. n.6. According to Campbell, longstanding principles and
policies of federal law recognize her right to raise this collateral challenge.
With the “sole exception of convictions obtained in violation of the right to
counsel,” the Supreme Court has recognized no constitutional right “to collaterally
attack prior convictions” during federal sentencing proceedings. Daniels v. United
7 Appellate Case: 24-5086 Document: 56-1 Date Filed: 05/05/2026 Page: 8
States, 532 U.S. 374, 378 (2001). McGirt did not expand upon this exception, see 591
U.S. at 935, and this court has not otherwise permitted the type of collateral
challenge Campbell seeks to pursue, see United States v. Garcia, 42 F.3d 573, 581
(10th Cir. 1994) (identifying “collateral attack based on the complete denial of
counsel” as the sole exception to the rule against collateral attacks of prior
convictions in sentencing proceedings). 4 The record confirms Campbell was
represented by counsel in each prior state criminal proceeding that resulted in a
conviction.
Campbell cites to Custis v. United States, in which the Supreme Court refused
to allow collateral attacks which did not rise “to the level of a jurisdictional defect
resulting from the failure to appoint counsel at all.” 511 U.S. 485, 496 (1994). From
the quoted language, she theorizes that, in addition to convictions obtained in
complete denial of counsel, judgments with jurisdictional defects may also be subject
to collateral challenges. This assertion, however, is at odds with both subsequent
decisions of the Supreme Court and the rationale underpinning the narrow exception
to the rule prohibiting collateral challenges.
4 While the Oklahoma Court of Criminal Appeals has affirmatively held McGirt does not apply retroactively, this court has not yet settled that question under federal law. Compare State ex rel. Matloff v. Wallace, 497 P.3d 686, 689 (Okla. Crim. App. 2021) (“[W]e now hold that McGirt. . . shall not apply retroactively to void a conviction that was final when McGirt was decided.”), with Pacheco v. Habti, 62 F.4th 1233, 1246 (10th Cir. 2023) (holding “McGirt announced no new constitutional right” but not addressing retroactivity). Because Campbell could not challenge the validity of her state convictions in this posture even if McGirt did apply retroactively, we need not address, and state no opinion on, McGirt’s retroactivity. 8 Appellate Case: 24-5086 Document: 56-1 Date Filed: 05/05/2026 Page: 9
In Johnson, a case decided more than a decade after Custis, the Supreme Court
explicitly “recognized only one exception to th[e] rule that collateral attacks were
off-limits, [which was] for challenges to state convictions allegedly obtained in
violation of the right to appointed counsel.” 544 U.S. at 303. Johnson was in keeping
with Daniels, which similarly held that collateral attacks during federal sentencing
proceedings may only be directed against state convictions obtained in complete
violation of the right to counsel. See 532 U.S. at 378. Notably, both Johnson, 544
U.S. at 303, and Daniels, 532 U.S. at 378, relied on, but did not interpret as broadly
as does Campbell, the holding of Custis. This court has not expanded upon the scope
of Custis either. In Garcia, this court, “applying Custis,” identified “collateral attack
based on the complete denial of counsel” as the sole exception to the general rule
against collateral challenges. 42 F.3d at 581.
Furthermore, Campbell’s position cannot be squared with the underlying
justifications for the narrow exception to the rule against collateral challenges to
prior convictions in federal sentencing proceedings. Custis offered two
considerations which militated against “extend[ing] the right to attack collaterally
prior convictions . . . beyond the right to have appointed counsel.” 511 U.S. at 496.
These considerations were “[e]ase of administration” and “[t]he interest in promoting
the finality of judgments.” Id. at 496-97. As to the former, Custis explained that
whereas “failure to appoint counsel at all will generally [be apparent] from the
judgment . . . itself,” other types of collateral challenges will likely “require
sentencing courts to rummage through frequently nonexistent or difficult to obtain
9 Appellate Case: 24-5086 Document: 56-1 Date Filed: 05/05/2026 Page: 10
state-court transcripts or records.” Id. at 496. As to the latter, the Supreme Court
expressed concern that “allowing collateral attacks would inevitably delay and impair
the orderly administration of justice and deprive the state-court judgment of its
normal force and effect.” Daniels, 532 U.S. at 378 (quoting Custis, 511 U.S. at 497).
Although there is no discernable dispute as to the circumstances of Campbell’s
prior convictions, as a general matter, establishing federal jurisdiction over criminal
conduct in Indian country may present complicated factual and legal issues. See, e.g.,
United States v. Hatley, 153 F.4th 1112, 1123-29 (10th Cir. 2025) (addressing
arguments disputing “fact of the defendant’s Indian status”); McGirt, 591 U.S. at
899-937 (interpreting, through extensive historical and legislative analysis, the
statutory definition of “Indian country” and whether the Creek Reservation could be
so classified). While district courts are fully capable of assessing such fact-intensive
jurisdictional claims, doing so might require meticulous review of records not so
easily accessible. See Daniels, 532 U.S. at 379. Interest in ease of administration
therefore weighs against permitting the type of collateral challenge Campbell seeks
to pursue.
As for the interest in preserving finality, states retain “a strong interest in
preserving the convictions it has obtained” even after the defendant has fully served
the sentence. Id. at 379. Although Campbell has served her sentence for all three
convictions, “if a state conviction were determined to be sufficiently unreliable that it
could not be used to enhance a federal sentence, the State’s ability to use that
judgment subsequently for its own purposes would be, at the very least, greatly
10 Appellate Case: 24-5086 Document: 56-1 Date Filed: 05/05/2026 Page: 11
undermined.” Id. at 380. Therefore, Oklahoma, which obtained the underlying
convictions, maintains “real and continuing interest in the integrity of its judgments.”
Id. Accordingly, allowing Campbell’s collateral challenge would be contrary to the
interest in preserving finality of state convictions.
In the end, Campbell fails to establish the sentences she served for her prior
state convictions fall outside of the scope of U.S.S.G. § 4A1.2(a). The district court
therefore did not err in considering her prior convictions when calculating her
Criminal History Category. The resulting Guidelines range does not reflect an abuse
of discretion.
IV. CONCLUSION
The district court did not abuse its discretion and its judgment is affirmed.
