ORDER AND JUDGMENT* _________________________________
Before BACHARACH, BALDOCK, and CARSON, Circuit Judges. _________________________________
A jury found Defendant Daniel Bayless guilty of four counts of Aggravated
Sexual Abuse in Indian Country. Pursuant to Federal Rule of Evidence 412, the district
court excluded evidence that Defendant’s victim, N.A., had made a prior,
“unsubstantiated” allegation of sexual abuse against another man when she was five
years old. Defendant appeals, arguing exclusion of this evidence violated his Sixth
Amendment right to confront the witnesses against him. But the Constitution does not

allegation against someone other than Defendant that cannot be proven true or false.
Exercising jurisdiction under 28 U.S.C. § 1291, we affirm Defendant’s conviction.
N.A. considered Defendant her father. She lived with Defendant’s mother, but
she and her younger siblings would sometimes spend weekends with Defendant at his
residence in Indian Country. Defendant lived with his sister, Kristen, and his
stepfather. But Defendant was often alone with the children, and N.A. would
commonly sleep with Defendant in his bedroom. From January to December 2020,
when N.A. was around nine years old, Defendant sexually abused her. N.A. disclosed
the abuse in 2022, telling Kristen first, then Defendant’s mother, and finally a friend,
whose mother became concerned for N.A.’s safety.
A Federal Grand Jury charged Defendant, an Indian, with four counts of
Aggravated Sexual Abuse in Indian Country in violation of 18 U.S.C. §§ 1151, 1153,
2241(c), and 2246(2)(A), (B). Defendant pleaded not guilty. Before trial, Defendant
expressed intent to enter evidence relating to a prior allegation of sexual abuse N.A.
had made years prior, when she was five years old. At that time, N.A. lived with her
mother and stepfather, Daniel Howe. When visiting Defendant’s mother, she said,
“someone I sleep with puts their hands down my panties.” She said it was her
stepfather, Howe. The Department of Human Services (DHS) investigated the
allegation and interviewed the family and N.A. But during the interview, N.A. denied
that her stepfather had ever touched her inappropriately. Instead, N.A. said she thought
Kristen touched her on her bottom but that N.A. was asleep when it happened. As N.A.
2 Appellate Case: 24-7033 Document: 56-1 Date Filed: 07/10/2025 Page: 3
denied that her stepfather had sexually abused her, DHS “UNSUBSTANTIATED” the
allegation against him.
The Government moved to exclude evidence relating to N.A.’s prior allegation
under Federal Rule of Evidence 412. Rule 412 applies to a civil or criminal proceeding
involving alleged sexual misconduct and prohibits the admission of “(1) evidence
offered to prove that a victim engaged in other sexual behavior; or (2) evidence offered
to prove a victim's sexual predisposition.” Fed. R. Evid. 412(a). But there are
exceptions to Rule 412. Evidence is admissible despite Rule 412(a) if exclusion of the
evidence “would violate the defendant’s constitutional rights.” Fed. R. Evid.
412(b)(1)(c). The Government conceded Rule 412 does not extend to evidence of prior
false claims. But the Government argued no evidence suggested N.A.’s prior
allegation was false, so Rule 412 barred admission of N.A.’s prior allegation. The
district court agreed, observing, “[w]hile DHS was not able to substantiate the
allegations, there is no evidence within the report that N.A. lied or made any false
allegations.” The court also concluded exclusion of N.A.’s prior allegation would not
violate Defendant’s constitutional rights, so the Rule 412(b)(1)(c) exception did not
apply. “[O]ut of an abundance of caution,” the court allowed the defense to ask N.A.
whether anyone had ever influenced her to lie about any sexual abuse allegation. But
the court granted the Government’s motion to exclude evidence relating to N.A.’s prior
allegation.
We review a district court’s exclusion of evidence under Rule 412 for abuse of
discretion. United States v. A.S., 939 F.3d 1063, 1070 (10th Cir. 2019). “A district
3 Appellate Case: 24-7033 Document: 56-1 Date Filed: 07/10/2025 Page: 4
court abuses its discretion only where it (1) commits legal error, (2) relies on clearly
erroneous factual findings, or (3) where no rational basis exists in the evidence to
support its ruling.” Dullmaier v. Xanterra Parks & Resorts, 883 F.3d 1278, 1295 (10th
Cir. 2018). But to the extent Defendant raises a constitutional challenge to the
exclusion of evidence, we review the district court’s exclusion of that evidence de
novo. A.S., 939 F.3d at 1071.
We first address Defendant’s reply-brief argument that Rule 412 does not extend
to N.A.’s prior “unsubstantiated” allegation. Defendant rightly observes Rule 412
prohibits evidence offered to prove one of two things: 1) “that a victim engaged in
other sexual behavior” or 2) “a victim’s sexual predisposition.” Fed. R. Evid. 412(a).
Defendant argues evidence of a prior “unsubstantiated” allegation does not fall into
either of those two categories but rather implicates N.A.’s credibility as a witness.
Thus, Defendant argues, evidence of N.A.’s prior allegation does not offend Rule 412
because Defendant is not offering the evidence for a prohibited purpose. But
Defendant waived this argument by failing to adequately raise it in his opening brief.

We review a district court’s exclusion of evidence under Rule 412 for abuse of
discretion. United States v. A.S., 939 F.3d 1063, 1070 (10th Cir. 2019). “A district
3 Appellate Case: 24-7033 Document: 56-1 Date Filed: 07/10/2025 Page: 4
court abuses its discretion only where it (1) commits legal error, (2) relies on clearly
erroneous factual findings, or (3) where no rational basis exists in the evidence to
support its ruling.” Dullmaier v. Xanterra Parks & Resorts, 883 F.3d 1278, 1295 (10th
Cir. 2018). But to the extent Defendant raises a constitutional challenge to the
exclusion of evidence, we review the district court’s exclusion of that evidence de
novo. A.S., 939 F.3d at 1071.
We first address Defendant’s reply-brief argument that Rule 412 does not extend
to N.A.’s prior “unsubstantiated” allegation. Defendant rightly observes Rule 412
prohibits evidence offered to prove one of two things: 1) “that a victim engaged in
other sexual behavior” or 2) “a victim’s sexual predisposition.” Fed. R. Evid. 412(a).
Defendant argues evidence of a prior “unsubstantiated” allegation does not fall into
either of those two categories but rather implicates N.A.’s credibility as a witness.
Thus, Defendant argues, evidence of N.A.’s prior allegation does not offend Rule 412
because Defendant is not offering the evidence for a prohibited purpose. But
Defendant waived this argument by failing to adequately raise it in his opening brief.
“[W]e routinely have declined to consider arguments that are not raised, or are
inadequately presented, in an appellant's opening brief.” Bronson v. Swensen, 500 F.3d
1099, 1104 (10th Cir. 2007); see also Burke v. Regalado, 935 F.3d 960, 1014 (10th
Cir. 2019) (“Issues not raised in the opening brief are deemed abandoned or waived.”
(citation omitted)). An adequate opening brief contains an argument section that
identifies “appellant's contentions and the reasons for them, with citations to the
authorities and parts of the record on which the appellant relies.” Fed. R. App. P.
4 Appellate Case: 24-7033 Document: 56-1 Date Filed: 07/10/2025 Page: 5
28(a)(8)(A)). This requirement is “designed to facilitate efficient appellate review by
allowing one's adversary to respond to focused argument supported by authority.”
Burke, 935 F.3d at 1014 (quoting MacArthur v. San Juan Cty., 495 F.3d 1157, 1160
(10th Cir. 2007)).
Here, Defendant’s opening brief fails to clearly assert and support his later
raised contention that Rule 412 does not apply to N.A.’s prior allegation. As best we
can tell, Defendant’s opening brief only mentions the issue in one sentence contained
in his summary of argument. Defendant says, “[t]his evidence is not barred by rape
shield laws because it pertains to the alleged victim’s truthfulness, not her sexual
behavior, as clarified in United States v. Pablo, 696 F.3d 1280 (10th Cir. 2012).”
Aplt’s Br. at 6. But this single sentence contained in Defendant’s summary of
argument and lacking reasoning and analysis is not enough to adequately raise an issue.
It is also unclear how the case Defendant cites, without a page number, supports his
point, and Defendant does not tell us. The rest of Defendant’s brief never clearly
addresses the issue, and the Government understandably believed Defendant conceded
it. Consequently, Defendant waived any challenge to Rule 412’s applicability here.
See A.S. 939 F.3d at 1072 (assuming Rule 412 applied to evidence of a prior sexual
assault allegation that could not be proven true or false where defendant did not
challenge Rule 412’s applicability on appeal).
Assuming Rule 412 extends to N.A.’s prior allegation, we next consider whether
an exception to Rule 412 applies under 412(b)(1)(c) because exclusion of the evidence
“would violate the defendant’s constitutional rights.” Defendant argues excluding
5 Appellate Case: 24-7033 Document: 56-1 Date Filed: 07/10/2025 Page: 6
evidence of N.A.’s prior allegation violated Defendant’s right “to be confronted with
the witnesses against him” under the Sixth Amendment’s Confrontation Clause. U.S.
Const. amend. VI. We review Defendant’s constitutional challenge de novo. See A.S.,
939 F.3d at 1071.
The Confrontation Clause guarantees criminal defendants “‘an opportunity for
effective cross-examination.’” United States v. Palms, 21 F.4th 689, 702 (10th Cir.
2021) (quoting Delaware v. Van Arsdall, 475 U.S. 673, 679 (1986). That said, “the
right is not limitless. It does not guarantee a defendant the right to cross-examine
witnesses ‘in whatever way, and to whatever extent, the defense might wish.’” Id.
(quoting Delaware v. Fensterer, 474 U.S. 15, 20 (1985)). More specifically,
“[e]vidence adduced by cross-examination concerning prior sexual intercourse may be
required to be admitted by Confrontation Clause rights where relevant and probative
on a central issue of sexual offense charges.” United States v. Powell, 226 F.3d 1181,
1198 (10th Cir. 2000). And we have recognized, “the class of cases in which evidence
otherwise barred by the rape shield statute has been deemed to be constitutionally
compelled is restricted to those which demonstrate a theory of witness bias or motive
to lie.” A.S., 939 F.3d at 1073 (citation omitted). Most significantly here, “the
Constitution does not mandate the admission of irrelevant or general impeachment
evidence.” Id. at 1074.
Defendant only offers evidence of N.A.’s prior allegation as general
impeachment evidence, but it serves even that non-constitutionally compelled purpose
poorly. Defendant does not argue N.A.’s prior allegation shows bias or motive to lie
6 Appellate Case: 24-7033 Document: 56-1 Date Filed: 07/10/2025 Page: 7
on the part of N.A. Nor could he. N.A. made the allegation against another man when
she was five years old, and the incident has nothing to do with Defendant. Rather than
arguing the evidence shows bias or motive to lie, Defendant argues the jury could infer
N.A. lied about the prior allegation because DHS “unsubstantiated” the investigation
against her stepfather. In other words, Defendant argues the evidence brings into
question N.A.’s general credibility. But Defendant points to nothing else in the DHS
Report to suggest falsity, and he does not otherwise challenge the district court’s
factual finding that the Report contains no evidence N.A. lied or made any false
statement. It is doubtful this unsubstantiated allegation N.A. made when she was five
years old says anything about her character for truthfulness. But in so far as this
evidence constitutes general impeachment evidence, under our precedents it is still not
required by the Confrontation Clause.
We AFFIRM Defendant’s conviction.
