except as provided by Ninth Circuit Rule 36-3.
Defendant King Umoren appeals his convictions and sentences underlying
two guilty pleas for fraudulent conduct related to the administration and sale of his
tax return preparation business. Because we assume the parties’ familiarity with
the facts, we recount them here only as necessary. The district court had
jurisdiction over both criminal matters pursuant to 18 U.S.C. § 3231. We have
jurisdiction pursuant to 28 U.S.C. § 1291 and 18 U.S.C. § 3742(a), and we affirm.
1. We “enforce the plain language of an appellate waiver” when the plea
language “cover[s] the grounds of the appeal” and when the waiver was
“knowingly and voluntarily made.” United States v. King, 985 F.3d 702, 710 (9th
Cir. 2021).
The appellate waiver’s plain language bars Umoren’s challenges to the
conviction and sentence resulting from the 2019 charges. The waiver plainly bars
his challenge to the 2019-related obstruction of justice enhancement because the
imposed sentence falls within the applicable Sentencing Guidelines range. The
waiver also bars Umoren’s challenge to the 2019-related Aggravated Identity Theft
(AIT) conviction because Umoren waived his right to challenge “any other aspect
of the conviction, including but not limited to the constitutionality of the statutes of
conviction.”
Umoren knowingly and voluntarily pled guilty, as demonstrated by the
district court’s compliance with Rule 11. See United States v. Covian-Sandoval,
2
462 F.3d 1090, 1093 (9th Cir. 2006). The Supreme Court’s decision in Dubin v.
United States, 599 U.S. 110 (2023), does not make his plea unknowing or
involuntary, even if it were to constitute a change in the law. See United States v.
Goodall, 21 F.4th 555, 562 (9th Cir. 2021) (“A change in the law does not make a
plea involuntary and unknowing.” (cleaned up)).
Umoren’s argument that he appeals an illegal sentence fails because he
claims that his conviction, not his sentence, is illegal. See id. at 563 (“The phrase
‘illegal sentence’ has a precise legal meaning, which does not include illegal
convictions.” (cleaned up)). Nor did the district court judge unequivocally re-
ignite Umoren’s right to appeal by informing him that he retained certain rights to
appeal. See United States v. Arias-Espinosa, 704 F.3d 616, 618–19 (9th Cir.
2012).
2. The district court did not err in applying the obstruction of justice
enhancement to Umoren’s 2016-related conviction, assuming, without deciding,
that the appellate waiver does not bar Umoren’s appeal of the 2016-related
enhancement. The Sentencing Guidelines provide for a two-level enhancement if
“(1) the defendant willfully obstructed or impeded, or attempted to obstruct or
impede, the administration of justice with respect to the investigation, prosecution,
or sentencing of the instant offense of conviction, and (2) the obstructive conduct
related to (A) the defendant’s offense of conviction and any relevant conduct; or
3
(B) a closely related offense.” U.S.S.G. § 3C1.1. This includes “destroying or
concealing . . . evidence that is material to an official investigation or judicial
proceeding.” Id. § 3C1.1 Application Note 4(D). Evidence is “material” where it
“would tend to influence or affect the issue under determination.” Id. § 3C1.1
Application Note 6.
The district court did not clearly err in finding that Umoren himself moved
the handgun, given Umoren’s statement that he took the handgun while
landscaping. See United States v. Castro-Ponce, 770 F.3d 819, 821–22 (9th Cir.
2014). And moving the handgun, in violation of the district court’s pretrial release
condition that Umoren “refrain from possessing a firearm,” constituted concealing
“evidence that is material to a[] . . . judicial proceeding.” See U.S.S.G. § 3C1.1
Application Note 4(D); United States v. Taylor, 749 F.3d 842, 846 (9th Cir. 2014)
(noting that we have affirmed the application of obstruction enhancements when
defendants impede pretrial release proceedings); United States v. Manning, 704
F.3d 584, 586 (9th Cir. 2012) (lying to pretrial services about possession of
firearms warranted obstruction of justice enhancement).
We reject Umoren’s argument that the district court erred in not entering a
finding of willfulness, where he did not object to the willfulness component of the
enhancement. Even so, the record amply supports the finding that Umoren
willfully obstructed justice, including that: he was aware that his pretrial release
4
conditions required him to refrain from possessing handguns, he was charged at the
time with being a prohibited person in possession of a firearm, the police informed
him that they may need his wife’s firearm,1 and he told his wife that they should
not be discussing handguns over the phone. See Manning, 704 F.3d at 585–86
(holding conduct obstructive when defendant violated pretrial release condition
and knew felon in possession investigation was underway). We also reject
Umoren’s argument that the handgun is immaterial because the government did not
attempt to retrieve it from Umoren’s possession. See United States v. Draper, 996
F.2d 982, 986 (9th Cir. 1993) (“It is sufficient that the conduct in question has the
potential for obstructing the investigation, prosecution, or sentencing of the instant
offense.”).
3. Umoren can challenge his 2016-related AIT conviction even if it will not
affect his sentence. See United States v. Zalapa, 509 F.3d 1060, 1064 (9th Cir.
2007) (“Imposition of an erroneously-imposed sentence, even a concurrent
sentence, can have significant collateral consequences that we cannot foretell at the
time of decision.”). His challenge fails, however, because Dubin, 599 U.S. at 110,
does not create a reasonable probability that Umoren would not have entered a
1
Although the record does not clearly indicate whether the handgun that Umoren
removed is the one that was used in the conduct underlying the impersonation
offense, the police’s instruction combined with the pretrial release conditions put
Umoren on notice that he should not hide firearms in his possession from the
government.

guilty plea. See United States v. David, 36 F.4th 1214, 1217 (9th Cir. 2022). First,
Dubin’s interpretation of the AIT statute affirmed existing Ninth Circuit law at the
time of Umoren’s guilty plea. See United States v. Hong, 938 F.3d 1040, 1051
(9th Cir. 2019). Second, Umoren’s falsification goes to “who” was involved in
making fraudulent tax claims and thus to “the crux of what makes the underlying
offense criminal.” Dubin, 599 U.S. at 114.
AFFIRMED.
