Harmless-Error Framework for Rule 32.1(b)(2)(C) Confrontation/Balancing Errors in Supervised-Release Revocations

Introduction

In United States v. Gaines (10th Cir. Mar. 27, 2026) (nonprecedential “Order and Judgment”), the Tenth Circuit affirmed a supervised-release revocation where the district court admitted a video (Exhibit 4) containing accusatory statements by the alleged shooting victim, Eric Williams, who did not testify. The defendant, Cregg Lenard Gaines, invoked Fed. R. Crim. P. 32.1(b)(2)(C) and the constitutional right to confrontation, arguing the district court failed to perform the required balancing between his confrontation interest and the government’s “good cause” for nonproduction.

The key appellate issue was narrow: whether admitting Exhibit 4 over the defendant’s Rule 32.1(b)(2)(C) objection required reversal. The panel assumed error—including assuming the error was of constitutional dimension—but held it harmless because the revocation finding would have been the same without the testimonial statements.

Summary of the Opinion

The Tenth Circuit:

  • Assumed the district court erred by admitting Exhibit 4 without adequately balancing the defendant’s confrontation interest against the government’s justification (as contemplated by the Rule 32.1 advisory committee notes).
  • Assumed (without deciding) the error could be “constitutional in nature.”
  • Affirmed on harmless-error grounds, concluding beyond a reasonable doubt the district court would still have found a violation by a preponderance of the evidence even if Exhibit 4’s testimonial statements were excluded.

The court emphasized that other evidence—officer testimony, physical evidence (shell casings, ammunition box, holster, firearm accessories/cleaning equipment), and Ring videos (Exhibits 1 and 2) showing the defendant holding a silver object and raising his arm as if pointing a firearm—provided an independent basis for revocation.

Analysis

Precedents Cited

1) Revocation burden of proof and standards of review

  • United States v. Adams, 888 F.3d 1134, 1138 (10th Cir. 2018): cited for the governing principle that a supervised-release violation need only be proven by a preponderance of the evidence under 18 U.S.C. § 3583(e)(3). This lower burden shaped the harmless-error inquiry: the appellate court asked whether, without Exhibit 4, the district court still would have found a violation under the preponderance standard.
  • United States v. Jones, 818 F.3d 1091, 1097 (10th Cir. 2016): supplied multiple doctrinal building blocks: (i) revocation decisions are reviewed for abuse of discretion; (ii) legal errors are reviewed de novo and constitute abuse of discretion; and (iii) preserved errors are disregarded if they do not affect substantial rights (via harmless-error doctrine). Jones also provided the key quotation from the Rule 32.1 advisory committee notes describing the required balancing between confrontation interests and governmental good cause.
  • United States v. LeCompte, 800 F.3d 1209, 1215 (10th Cir. 2015): cited through Jones for the revocation abuse-of-discretion standard, reinforcing appellate deference to revocation determinations absent legal error.
  • United States v. Faunce, 66 F.4th 1244, 1257 (10th Cir. 2023) and United States v. Henry, 852 F.3d 1204, 1207 (10th Cir. 2017): cited for the proposition that a district court’s evidentiary decisions in revocation proceedings— including allowing testimony—are reviewed for abuse of discretion. These cases frame the admission of Exhibit 4 as a discretionary evidentiary ruling constrained by Rule 32.1 and due process.
  • United States v. Weidner, 437 F.3d 1023, 1042 (10th Cir. 2006): provided the articulation of abuse of discretion as decisions that are “arbitrary or capricious or result[] in a manifestly unreasonable judgment,” anchoring the review framework even though the panel ultimately resolved the appeal on harmlessness.

2) Harmless error for constitutional violations

  • Chapman v. State of Cal., 386 U.S. 18, 24 (1967): supplied the governing harmless-error standard for constitutional errors: reversal is required unless the government proves harmlessness beyond a reasonable doubt. Gaines applies Chapman in the revocation context by asking whether, beyond a reasonable doubt, the district court still would have found a violation under the preponderance standard even without the challenged evidence.

3) Testimonial statements and confrontation principles

  • Crawford v. Washington, 541 U.S. 36, 68 (2004): cited for the principle that the Confrontation Clause requires exclusion of “testimonial” statements. The panel did not decide whether Exhibit 4 contained testimonial statements that must be excluded in a revocation proceeding; instead, it assumed error for purposes of the appeal and found harmlessness. Crawford’s role here is definitional: it supplies the “testimonial” vocabulary used to isolate the problematic portion of Exhibit 4.

Legal Reasoning

  1. Rule 32.1(b)(2)(C) requires a balancing inquiry when confrontation is invoked. The opinion reiterates that when a releasee seeks to question an adverse witness, the court must balance “the person’s interest in the constitutionally guaranteed right to confrontation against the government’s good cause for denying it” (via the Rule 32.1 advisory committee notes, quoted in United States v. Jones). The panel assumed the district court did not adequately perform this balancing before admitting Exhibit 4.
  2. Even preserved constitutional error can be affirmed if harmless beyond a reasonable doubt. Applying Chapman v. State of Cal., the panel held it could affirm if the government proved that any assumed confrontation/balancing error did not affect the outcome.
  3. Harmlessness is assessed against the revocation burden (preponderance) and the record as a whole. The panel articulated a revocation-specific formulation: the government had to show beyond a reasonable doubt that, absent Exhibit 4, the district court still would have found by a preponderance that revocation was warranted. On this record, the panel concluded the district court’s reasoning substantially rested on:
    • Officer Awad’s testimony about the investigation and evidence recovered;
    • Physical evidence: .25 caliber shell casings, empty .25 ammunition box, holster, and firearm-related items;
    • Ring videos (Exhibits 1 and 2) depicting the defendant near the victim’s apartment holding a small silver object and later extending/raising his arm in a way consistent with pointing a firearm, along with the victim’s remark in Exhibit 2 (“Are you going to shoot me, cuz?”);
    • Exhibit 3 identifying the defendant.
    Critically, the panel noted the district court discussed and drew inferences from Exhibits 1 and 2 and other evidence before turning to Exhibit 4, supporting the conclusion that Exhibit 4 was not outcome-determinative.
  4. The court separated the video’s visual inference from its testimonial statements. Even while assuming the testimonial statements were improperly admitted, the panel observed that the video’s nonverbal, visual depiction (victim present with an injured leg; defendant nearby) could support permissible inferences independent of the accusatory narration—further reinforcing harmlessness.

Impact

Although expressly “not binding precedent,” Gaines is significant in three practical ways within revocation litigation:

  • It clarifies a revocation-specific harmless-error framing. The opinion ties together (i) Chapman’s “beyond a reasonable doubt” harmlessness standard (assuming constitutional error) with (ii) the revocation burden of proof (preponderance), yielding a two-level inquiry: whether the same preponderance finding would occur even without the contested evidence.
  • It signals that failure to conduct the Rule 32.1 balancing may be affirmable on a strong record. District courts are still expected to perform the balancing, but Gaines demonstrates that appellate courts may affirm when other evidence independently supports the violation finding.
  • It encourages litigants to develop (and courts to articulate) alternative grounds. The harmlessness analysis turned on the sequence and substance of the district court’s reasoning—what it relied upon before reaching the challenged exhibit—suggesting that careful findings can reduce reversal risk.

Complex Concepts Simplified

Supervised-release revocation vs. criminal trial
Revocation is not a new criminal conviction. The government need only prove a violation by a preponderance of the evidence (more likely than not), not beyond a reasonable doubt.
Rule 32.1(b)(2)(C) “question any adverse witness”
In a revocation hearing, a defendant generally may question (cross-examine) adverse witnesses. The court can deny that right only if “the interest of justice” does not require the witness to appear—implemented through a balancing of the defendant’s confrontation interest against the government’s good cause for nonproduction.
“Testimonial” statements
Under Crawford v. Washington, the Confrontation Clause is primarily concerned with statements that are “testimonial”—typically formal statements made for use in prosecution. Gaines assumed (without deciding) that the challenged statements in Exhibit 4 were testimonial for purposes of addressing the argument.
Harmless error (constitutional)
Even if the court committed a constitutional error, an appellate court can affirm if the government proves beyond a reasonable doubt the error did not affect the outcome. Here, that meant proving the judge still would have found a supervised-release violation by a preponderance without Exhibit 4.
Abuse of discretion
A deferential appellate standard. A decision is reversed only if it is arbitrary, capricious, or manifestly unreasonable, or if it rests on legal error.
Hearsay exceptions (excited utterance / present sense impression)
These are rules that sometimes allow out-of-court statements to be admitted for their truth because circumstances suggest reliability (e.g., statements made during a startling event or immediately as events unfold). In Gaines, the district court referenced these exceptions, but the appeal centered on confrontation and Rule 32.1 balancing rather than hearsay doctrine.

Conclusion

United States v. Gaines underscores that, in supervised-release revocation proceedings, a district court’s failure to conduct the Rule 32.1(b)(2)(C) confrontation/good-cause balancing—even if assumed to be a preserved, constitutional-level error—does not mandate reversal when the government can show the error was harmless beyond a reasonable doubt. The opinion’s practical lesson is twofold: district courts should expressly perform and record the required balancing when adverse witnesses are not produced, and litigants should recognize that robust independent evidence can render confrontation-related errors harmless in the revocation setting.
