v. No. 25-5008 (D.C. No. 4:23-CR-00288-JDR-1) KENYON RAY VESSELL, (N.D. Okla.)
Defendant - Appellant. _________________________________
ORDER AND JUDGMENT* _________________________________
Before BACHARACH, McHUGH, and FEDERICO, Circuit Judges. _________________________________
In August 2022, Defendant Kenyon Ray Vessell was driving about 113 miles
per hour in a 65-miles-per-hour zone, and he was under the influence of marijuana.
He struck a vehicle, killing one occupant and severely injuring another. Because
Vessell is an enrolled member of a Native American tribe and his crime happened in
Indian Country, the federal government had jurisdiction over the matter, and a grand
jury in the Northern District of Oklahoma charged him with second-degree murder
and assault resulting in serious bodily injury.
* This order and judgment is not binding precedent, except under the doctrines of law of the case, res judicata, and collateral estoppel. It may be cited, however, for its persuasive value consistent with Fed. R. App. P. 32.1 and 10th Cir. R. 32.1. Appellate Case: 25-5008 Document: 29 Date Filed: 06/04/2025 Page: 2
As part of a plea deal, Vessell pleaded guilty to involuntary manslaughter (as
opposed to second-degree murder) and assault resulting in serious bodily injury.
Then, at sentencing, the district court imposed an 84-month prison sentence for each
count of conviction, running concurrently.
Vessell now appeals his sentence, but his plea agreement contains an appeal
waiver. The government therefore moves to enforce that waiver under United States
v. Hahn, 359 F.3d 1315, 1328 (10th Cir. 2004) (en banc). Hahn requires this court to
ask three questions: “(1) whether the disputed appeal falls within the scope of the
waiver of appellate rights; (2) whether the defendant knowingly and voluntarily
waived his appellate rights; and (3) whether enforcing the waiver would result in a
miscarriage of justice.” Id. at 1325.
Vessell’s counsel filed a response stating “that opposition to the Motion would
be frivolous.” Resp. to Aplee. Mot. to Dismiss at 1; see also Anders v. California,
386 U.S. 738, 744 (1967) (“[I]f [defense] counsel finds [the defendant’s] case to be
wholly frivolous, after a conscientious examination of it, he should so advise the
court . . . .”). In particular, counsel examined the three Hahn factors and concluded
there were no viable arguments to make on Vessell’s behalf. The court therefore
invited Vessell to file a pro se response. See id. (“A copy of counsel’s brief should be
furnished the [defendant] and time allowed him to raise any points that he chooses
. . . .”). Vessell filed such a response. For the reasons explained below, we grant the
government’s motion.
2 Appellate Case: 25-5008 Document: 29 Date Filed: 06/04/2025 Page: 3
I. ANALYSIS
A. Scope of the Waiver
Again, our first question when faced with a motion to enforce an appeal waiver
is “whether the disputed appeal falls within the scope of the waiver.” Hahn, 359 F.3d
at 1325. As to this, Vessell asserts three arguments, which we discuss in turn.
1. Need to Identify Appellate Arguments at this Stage
Vessell says he should not be required to explain his appellate arguments at
this preliminary stage. But Hahn effectively settled this issue, stating that “appellate
waivers benefit the government by saving the costs of prosecuting appeals; and only
through the efficient dismissal of an appeal will the government receive the benefit of
its bargain.” 359 F.3d at 1325 (brackets and internal quotation marks omitted). Hahn
therefore established the procedure that the government has now invoked. See id.
Thus, despite the preliminary nature of the appeal, Vessell is indeed required to
explain what arguments he hopes to bring. Otherwise, this court cannot determine if
his appeal falls within the scope of the waiver and the Hahn procedure is defeated.
2. Ineffective Assistance of Counsel
Vessell next says he received ineffective assistance of counsel. Specifically, at
his sentencing hearing, the district court decided to vary upwards from the agreed-
upon Guidelines range because the court believed the Guidelines range did not
adequately reflect the seriousness of Vessell’s crime, his criminal history, and the
need for deterrence. The district court also viewed the facts of the case as more like
second-degree murder (as the grand jury had charged) than involuntary manslaughter.
3 Appellate Case: 25-5008 Document: 29 Date Filed: 06/04/2025 Page: 4
Although Vessell’s attorney contested much of the district court’s reasoning, Vessell
claims she never straightforwardly challenged the analogy to second-degree murder.
This, Vessell argues, amounted to ineffective assistance of counsel, which he believes
falls outside the scope of the appeal waiver.
Vessell is confusing his waiver of the right to bring a direct appeal (this
appeal) and his waiver of the right to collaterally attack his conviction (such as
through 28 U.S.C. § 2255). The direct-appeal waiver contains only one exception,
namely, if the district court imposes “a sentence that exceeds the statutory
maximum.” Mot. to Enforce, Attach. 1 at 3. There is no exception for a claim of
ineffective assistance. Rather, ineffective assistance is an exception to his waiver of
the ability to bring a collateral attack. See id. Thus, according to the plain terms of
the plea agreement, ineffective assistance does not escape his appellate waiver. See
United States v. Porter, 405 F.3d 1136, 1142 (10th Cir. 2005) (rejecting a scope-of-
waiver argument because the defendant’s “interpretation of the waiver clause
contradict[ed] the plain language of the plea agreement”).
3. Illegal Sentence
Finally, Vessell argues he received an illegal sentence, and he further argues
that appeal waivers cannot insulate illegal sentences from review. He does not tell us
what he means by “illegal sentence” (e.g., do all sentencing errors result in an illegal
sentence?), but that is unimportant here because his argument that he received an
illegal sentence, even if true, could not avoid the waiver.
4 Appellate Case: 25-5008 Document: 29 Date Filed: 06/04/2025 Page: 5
Vessell points out that his sentence includes three years of supervised release,
and he claims that courts are beginning to realize “there are serious Constitutional
questions about the continuing legality of supervised release.” Opp’n to Mot. to
Dismiss at 4.1 Whether accurate or not, it would not bring this appeal outside the
scope of the waiver, as illustrated by our Porter decision.

that appeal waivers cannot insulate illegal sentences from review. He does not tell us
what he means by “illegal sentence” (e.g., do all sentencing errors result in an illegal

4 Appellate Case: 25-5008 Document: 29 Date Filed: 06/04/2025 Page: 5
Vessell points out that his sentence includes three years of supervised release,
and he claims that courts are beginning to realize “there are serious Constitutional
questions about the continuing legality of supervised release.” Opp’n to Mot. to
Dismiss at 4.1 Whether accurate or not, it would not bring this appeal outside the
scope of the waiver, as illustrated by our Porter decision.
In Porter, the defendant’s appeal waiver contained an exception for “a
sentence ‘above the maximum statutory penalty provided in the statute of
conviction.’” 405 F.3d at 1142. The defendant nonetheless hoped to argue that the
Supreme Court’s then-recent decision in Blakely v. Washington, 542 U.S. 296 (2004),
showed that the U.S. Sentencing Guidelines were unconstitutional. Porter, 405 F.3d
at 1142 & n.2. While his appeal was pending, the Supreme Court held that the
reasoning of Blakely indeed rendered the Guidelines unconstitutional to the extent
they were mandatory. See United States v. Booker, 543 U.S. 220, 226–27 (2005).
The defendant then submitted additional briefing claiming that “Booker error is
structural error not subject to plain error review.” Porter, 405 F.3d at 1142 n.2. We
1 He says this is evident in United States v. Haymond, 588 U.S. 634 (2019). Haymond examined the constitutionality of a statute requiring a mandatory minimum of five years in prison for certain supervised-release violations. Id. at 639 (plurality op.). A four-justice plurality held the statute was unconstitutional for essentially the same reasons that facts which increase the mandatory minimum or statutory maximum penalties may not be used to increase a sentence unless found by a jury or conceded. Id. at 643–46. Justice Breyer, writing for himself, found the statute unconstitutional on narrower grounds. Id. at 657–59. The dissent would have upheld the statute and accused the plurality opinion of “suggest[ing] that the entire system of supervised release, which has been an integral part of the federal criminal justice system for the past 35 years, is fundamentally flawed in ways that cannot be fixed.” Id. at 660 (Alito, J., dissenting). 5 Appellate Case: 25-5008 Document: 29 Date Filed: 06/04/2025 Page: 6
stated, however, that we were “not required to reach the merits of these claims
because we [found] the plea agreement enforceable.” Id. We elaborated that the
exception for sentences above the statutory maximum meant exactly what it said, and
nothing beyond that. Id. at 1142–43. In short, the defendant in Porter had a winning
argument that the Guidelines were unconstitutional, but his appeal waiver still
applied because there was no exception for that argument.
Vessell’s appeal waiver, like that of the Porter defendant, contains an
exception only for “a sentence that exceeds the statutory maximum.” Mot. to
Enforce, Attach. 1 at 3. Whether or not he has a viable constitutional attack on
supervised release, it is not within the scope of that exception. And as Porter
illustrates, the fact it is a constitutional argument does not change the analysis.
4. This Court’s Review of the Record
In a situation such as this, where the defense attorney concludes there is no
nonfrivolous argument to make on behalf of the defendant, this court must make “a
full examination of all the proceedings” to ensure defense counsel is correct. Anders,
386 U.S. at 744. We accordingly note that Vessell’s 84-month prison sentence is
lower than the statutory maximum of eight years for involuntary manslaughter, see
18 U.S.C. § 1112(b), and ten years for assault resulting in serious bodily injury, see
id. § 113(a)(6). Thus, this appeal does not come within the explicit exception to the
appeal waiver.
We have also reviewed the plea agreement and the change-of-plea proceedings.
One passage from the change-of-plea hearing transcript catches our attention. There,
6 Appellate Case: 25-5008 Document: 29 Date Filed: 06/04/2025 Page: 7
the district court loosely summarized the scope of the waiver: “Do you understand
that about the only exception to this broad waiver . . . of your right to file a direct
appeal or a collateral attack would be if you could somehow show ineffective
assistance of counsel by [your attorney]?” Mot. to Enforce, Attach. 3 at 26. This
summary may be why Vessell believes he may bring an ineffective-assistance claim
at this stage. But the plea agreement concludes with an integration clause stating that
it contains the parties’ whole agreement and cannot be changed unless the change is
“executed in writing and signed by all of the parties.” Id., Attach. 1 at 15. Thus, if
the district court’s summary was inconsistent with the plea agreement, the plea
agreement controls. Cf. United States v. Rockwell Int’l Corp., 124 F.3d 1194, 1199–
1200 (10th Cir. 1997) (refusing, in light of an integration clause, to consider evidence
that a plea agreement contained an unwritten term); United States v. Montano,
472 F.3d 1202, 1205 (10th Cir. 2007) (“[A judge’s] oral modification of an accepted
plea agreement [at sentencing] does not alter the substance of the agreement.”).
For all these reasons, we conclude this appeal falls within the scope of the
waiver.
B. Knowing and Voluntary Waiver
Vessell offers no argument that he unknowingly or involuntarily waived his
appeal rights. Reviewing the matter ourselves, we note that Vessell initialed each
page of his plea agreement (including the page containing the appeal waiver) and
signed the agreement, and the district court confirmed Vessell’s understanding and
acceptance of the waiver during the change-of-plea hearing. But this also brings us
7 Appellate Case: 25-5008 Document: 29 Date Filed: 06/04/2025 Page: 8
back to the matter just discussed, i.e., the district court’s loose summary of the appeal
and collateral attack waivers, and what that summary could have led Vessell to
believe about his ability to bring an ineffective-assistance claim on appeal. In theory,
it could raise a question of whether Vessell knowingly agreed to the terms of the
appeal waiver. But we ultimately find no nonfrivolous argument that Vessell might
have made on this account.
We have apparently not established whether a district court’s misleading
statement in this context (assuming it was misleading) should be reviewed for
harmless error or, if not objected to in the district court, for plain error. Neither
standard yields a viable argument.
Assuming the standard is harmless error, the district court’s misstatement of
the appeal waiver’s scope was harmless because Vessell did not lose his ability to
bring an ineffective-assistance claim, he simply must bring it through a collateral
attack rather than on direct appeal. Indeed, under the circumstances, he must bring
his claim through a collateral attack because the record is not adequately developed
to consider the claim in this appeal.2
2 “Generally, we only consider ineffective assistance of counsel claims on collateral review.” Hahn, 359 F.3d at 1327 n.13. Vessell claims this is one of those “rare [ineffective assistance] claims which are fully developed in the record [and] may be brought . . . on direct appeal,” United States v. Galloway, 56 F.3d 1239, 1242 (10th Cir. 1995), but he is incorrect. Ineffective assistance requires: (1) constitutionally deficient performance by the defense attorney that (2) prejudices the defendant. Strickland v. Washington, 466 U.S. 668, 687 (1984). Vessell’s argument relates only to the first requirement. Even if the record were adequately developed as to that requirement (and we offer no opinion on that), the record is not developed as to the second requirement—or in other words, whether the argument 8 Appellate Case: 25-5008 Document: 29 Date Filed: 06/04/2025 Page: 9
Assuming the standard is plain error, Vessell would be required to establish
that the error affected his substantial rights, meaning he suffered prejudice. See
United States v. Edgar, 348 F.3d 867, 872 (10th Cir. 2003). And in this context,
prejudice means “he would not have pleaded guilty” but for the alleged error. Id.
Neither the record nor Vessell’s appellate filings give us any reason to believe his
decision to plead guilty stood or fell with the relatively obscure question of when and
where he could raise an ineffective-assistance claim.
We thus see no path by which the district court’s oral summary of the appeal
waiver could result in a knowing-and-voluntary argument sufficient to overcome the
C. Miscarriage of Justice
In this context, a miscarriage of justice occurs “[1] where the district court
relied on an impermissible factor such as race, [2] where ineffective assistance of
counsel in connection with the negotiation of the waiver renders the waiver invalid,
[3] where the sentence exceeds the statutory maximum, or [4] where the waiver is
otherwise unlawful.” Hahn, 359 F.3d at 1327 (bracketed numerals in original;
internal quotation marks omitted).
Vessell returns to his claim that he should not be required to explain his appeal
arguments at this preliminary stage, and he says it is a miscarriage of justice to do so.
Vessell’s attorney allegedly missed would have made any difference to the district court in its upward-variance decision. See id. at 694 (defining prejudice as “a reasonable probability that, but for counsel’s unprofessional errors, the result of the proceeding would have been different”). 9 Appellate Case: 25-5008 Document: 29 Date Filed: 06/04/2025 Page: 10
This cannot qualify as a miscarriage of justice in this context. See United States v.
Shockey, 538 F.3d 1355, 1357 (10th Cir. 2008) (noting that the four miscarriage-of-
justice possibilities enumerated in Hahn are “exclusive”).
If Vessell’s illegal-sentence argument, discussed above, was also meant as a
claim that his waiver is otherwise unlawful, we disagree. We have already “rejected
. . . the assertion that the occurrence of constitutional errors during sentencing is
sufficient to establish that the waiver itself was unlawful.” United States v. Holzer,
32 F.4th 875, 887 (10th Cir. 2022).3
Having independently reviewed the record, we do not discern any nonfrivolous
argument that would meet the Hahn miscarriage-of-justice standard. We therefore
find no miscarriage of justice.
D. Vessell’s Second Pro Se Response
Eleven days after the court received Vessell’s pro se response, the court
received a second response from him. In this filing, Vessell claims he instructed his
attorney not to file an Anders brief, or at least to withdraw before filing an Anders
brief, so he would not be prejudiced by his own attorney stating that his case was
frivolous. He further complains that his attorney’s Anders brief was not an adequate
Anders brief because it failed to attack the judge’s upward variance. Finally, he asks
the court to allow him to proceed pro se.
3 To be clear, we do not conclude that any constitutional error infects Vessell’s sentence. We express no opinion on that either way. Holzer establishes, however, that such an error would not make the appeal waiver unlawful. 10 Appellate Case: 25-5008 Document: 29 Date Filed: 06/04/2025 Page: 11
By inviting and accepting his pro se response to the government’s motion, the
court is already allowing Vessell to proceed pro se, so this request is moot. The
remainder of his arguments change nothing about our disposition of this appeal.
First, a client cannot prevent counsel from filing an Anders brief. “[C]ounsel
is under ethical obligations to the client and to the court.” United States v. Calderon,
428 F.3d 928, 931 (10th Cir. 2005) (emphasis added). If counsel has concluded there
is no nonfrivolous basis to oppose the government’s motion to dismiss, counsel is
“performing the function of [an] officer of the court” when he or she tells us as much.
Id.
Second, the client suffers no prejudice when counsel files an Anders brief. It
is “the court—not counsel—[that] proceeds, after a full examination of all the
proceedings, to decide whether the case is wholly frivolous.” Anders, 386 U.S.
at 744. We do not defer to counsel’s opinion of that matter.
Third, counsel’s failure to raise the upward-variance issue does not show that
she shirked her Anders duties. In the current context, the question is not whether
there is any nonfrivolous basis for reversing the district court’s judgment, but
whether there is any nonfrivolous basis for overcoming the appeal waiver. As we
have already explained, Vessell’s argument about the upward variance, even if framed
as ineffective assistance of counsel, cannot overcome the appeal waiver. In any
event, Vessell suffered no prejudice because he raised the argument himself.

II. CONCLUSION
We grant the government’s motion to enforce the appeal waiver and dismiss
this appeal.
