Standing to Appeal Requires a Conviction: Post‑Verdict Dismissal of a Count Moots Challenges to Pretrial Denial of Dismissal

1. Introduction

In United States v. Clements (10th Cir. Aug. 17, 2026), the Tenth Circuit confronted a procedural question that arises when litigation events “erase” the judgment a defendant seeks to challenge: may a defendant appeal the denial of a pretrial motion to dismiss a criminal count when the count is dismissed after trial and the defendant is never convicted or sentenced on that count?

The case involved multiple charges stemming from allegations that Kevin Dwight Clements kidnapped and sexually abused his stepdaughter and used a firearm in the course of the abuse. Relevant here, the government charged firearm possession counts including (i) possessing a firearm while being a drug user or addict, and (ii) possessing a firearm after a felony conviction. Before trial, Mr. Clements moved to dismiss the firearm-possession charges on constitutional grounds. The district court denied the motion. After a jury found him guilty on all counts, the government moved to dismiss the “drug user or addict” firearm-possession count to avoid two convictions for the same act of possession, and the district court granted that post-verdict dismissal. Mr. Clements remained convicted on the other counts.

On appeal, Mr. Clements sought review of (a) the district court’s failure to dismiss the “drug user or addict” count earlier, contending that the pretrial denial led to prejudicial drug-use evidence; and (b) the constitutionality of the felon-in-possession charge; and (c) admission of prior sexual-abuse testimony under Federal Rule of Evidence 413.

2. Summary of the Opinion

  • No standing to challenge the pretrial denial of dismissal of the “drug user or addict” firearm-possession count because the count was dismissed after trial, leaving no conviction or sentence to appeal; any ruling on the statute’s constitutionality would be academic. The court dismissed that part of the appeal.
  • Mr. Clements’s Second Amendment challenge to the felon-in-possession statute was foreclosed by Vincent v. Bondi.
  • The district court properly admitted testimony from two women about prior sexual abuse under Federal Rule of Evidence 413, because under United States v. Clay Rule 413 turns on the circumstances of the alleged conduct, not the formal label of the charged offense.
  • Overall disposition: Affirmed as to the remaining issues; the constitutional challenge to the dismissed “drug user or addict” count was dismissed for lack of standing.

3. Analysis

3.1. Precedents Cited

A. Standing, appealability, and mootness when there is no conviction

  • United States v. Parr, 351 U.S. 513, 518 (1956)
    The panel relied on Parr for the baseline proposition that a defendant can ordinarily challenge only a conviction or sentence—not a freestanding pretrial ruling once the case posture eliminates the conviction on the count at issue. Parr frames the appellate role as reviewing judgments that impose legal consequences.
  • McKinney v. Gannett Co., 694 F.2d 1240, 1247-48 (10th Cir. 1982)
    Cited for the concept that courts do not decide academic questions. Here, because the drug-user firearm count was dismissed post-verdict, deciding the statute’s constitutionality would not affect a judgment against Mr. Clements on that count.
  • United States v. MacDonald, 456 U.S. 1, 10 (1982)
    MacDonald supplied the key analogy: absent a conviction or sentence after dismissal, the legal posture is “as though no charges had been made” on that count. The court used this framing to explain why the statute itself inflicted no judicially cognizable injury on Mr. Clements once the count was dismissed.
  • United States v. Risner, 129 F.4th 361, 366 (6th Cir. 2025)
    The panel treated Risner as persuasive support for the specific standing rule: when a district court denies a pretrial constitutional motion to dismiss a count, but the count is later dismissed (there, pursuant to a plea agreement), the defendant lacks standing to appeal the earlier denial because there is no conviction on that count. Clements adopts the same standing logic in the post-verdict dismissal context.

B. “Spillover” evidence and preservation/waiver

  • United States v. Simon, 12 F.4th 1, 43 (1st Cir. 2021)
    The government characterized Mr. Clements’s complaint as a “spillover” problem—where evidence admitted to prove one count spills into the jury’s consideration of other counts. Although the Tenth Circuit did not adjudicate a spillover claim, Simon framed the doctrinal label for the government’s argument and the court’s discussion of what Mr. Clements was (and was not) appealing.
  • United States v. Wright, 363 F.3d 237, 248 (3d Cir. 2004)
    Used to illustrate procedural obstacles to litigating spillover-type prejudice when a defendant has not properly pursued the issue in the district court (there, by not moving for a new trial on the relevant ground). In Clements, the point reinforced that evidentiary prejudice is typically litigated through preserved evidentiary objections and related motions.
  • United States v. Tee, 881 F.3d 1258, 1274 n.3 (10th Cir. 2018)
    Tee supplied the proposition that unpreserved issues can sometimes be reviewed for plain error. The court noted this pathway but emphasized it was unavailable here because Mr. Clements did not request plain-error review.
  • United States v. Richardson, 136 F.4th 1261, 1269 (10th Cir. 2025)
    Richardson anchored the waiver holding: failing to request plain-error review for an unpreserved issue constitutes waiver of that argument on appeal. This mattered because the only plausible injury from the dismissed count was evidentiary (drug-use evidence), yet Mr. Clements did not pursue that evidentiary argument in a preserved posture.

C. Merits foreclosed by binding circuit precedent

  • Vincent v. Bondi, 127 F.4th 1263 (10th Cir. 2025)
    The panel treated Vincent as dispositive of Mr. Clements’s Second Amendment challenge to the statute criminalizing firearm possession after a felony conviction. Because Vincent is binding within the Tenth Circuit, the court rejected the challenge without revisiting the underlying constitutional analysis.

D. Federal Rule of Evidence 413 and the meaning of “a case” where the defendant is “accused of sexual assault”

  • United States v. Benally, 500 F.3d 1085, 1090 (10th Cir. 2007)
    Cited for the general rule that Federal Rule of Evidence 413(a) permits evidence of uncharged sexual assaults in a criminal case when the defendant is accused of sexual assault. Benally provides the doctrinal foundation for admitting propensity-type evidence in this specific context.
  • United States v. Clay, 148 F.4th 1181, 1195-98 (10th Cir. 2025)
    Clay was the controlling interpretation that resolved Mr. Clements’s argument that Rule 413 does not apply because he was charged with sex trafficking (not a generic “sexual assault” charge). Under Clay, Rule 413 turns on the circumstances of the conduct alleged, not the formal statutory label. That reading allowed admission of the prior sexual abuse testimony.

3.2. Legal Reasoning

  1. Standing requires an injury traceable to the challenged action and redressable by the court.
    The court treated the “injury” inquiry as decisive. Once the government moved post-verdict to dismiss the “drug user or addict” firearm count and the district court granted dismissal, Mr. Clements had no conviction and no sentence on that count. Without a judgment imposing legal consequences on that count, the court viewed an appellate ruling on the statute’s constitutionality as purely academic (McKinney).
  2. The absence of a conviction makes the posture “as though no charges had been made.”
    Invoking MacDonald, the court reasoned that the dismissal functionally eliminated the count from the case’s outcome. That framing undercut any claim that the statute itself injured Mr. Clements once the count disappeared from the judgment.
  3. Attempting to reframe the injury as evidentiary prejudice did not supply standing for a constitutional challenge.
    Mr. Clements pointed to the introduction of drug-use evidence as harmful fallout from the pretrial denial, but he disavowed a freestanding spillover claim (described by reference to Simon). The court effectively treated this as a mismatch between the alleged injury (evidence) and the legal attack (constitutionality of the statute). If the only remaining injury is evidentiary, it must be litigated through evidentiary error doctrines—not through a constitutional challenge to a count that produced no conviction.
  4. Procedural default blocked an evidentiary route.
    The opinion noted that Mr. Clements did not object at trial, did not preserve an admissibility claim, and—critically—did not request plain-error review, resulting in waiver under Richardson (with Tee explaining the plain-error pathway that was not invoked).
  5. On remaining issues, binding precedent controlled.
    For the felon-in-possession Second Amendment challenge, Vincent v. Bondi foreclosed relief. For Rule 413, Clay dictated that the applicability of Rule 413 depends on conduct circumstances rather than the formal charge label, and Benally supported the general admissibility of uncharged sexual assaults in qualifying cases.

3.3. Impact

  • Appellate standing in criminal cases is tightly tethered to the judgment.
    Clements underscores a practical rule: if a count is dismissed such that there is no conviction or sentence on that count, the defendant generally cannot obtain appellate review of a pretrial denial of a motion to dismiss that count, even if the defendant believes the pretrial ruling affected trial dynamics.
  • Litigants must align the theory of injury with the theory of relief.
    The opinion signals that “pretrial constitutional challenge” is not an all-purpose vehicle for later trial-prejudice complaints. If the real grievance is that evidence should not have been admitted, the proper channel is an evidentiary objection and corresponding appellate argument (including plain-error review if unpreserved).
  • Preservation and plain-error requests are outcome-determinative.
    By emphasizing waiver when the appellant does not request plain-error review, the decision incentivizes careful appellate briefing: defendants must expressly invoke plain error when needed, or risk losing the only viable route to address unpreserved evidentiary prejudice.
  • Rule 413 breadth continues to expand via “conduct-based” interpretation.
    By applying Clay, the panel reinforced that Rule 413 can apply even when the indictment does not use the label “sexual assault,” so long as the alleged conduct in the case qualifies—an important evidentiary holding for trafficking/kidnapping prosecutions with sexual components.

4. Complex Concepts Simplified

Standing
A threshold requirement that the appellant has suffered (or will suffer) a concrete legal injury that an appellate court can fix. Here, without a conviction on the dismissed count, the court saw nothing to “fix” via ruling on that statute’s constitutionality.
Mootness / “Academic” questions
Courts generally avoid deciding issues that won’t change the parties’ legal rights. If the count is dismissed and no conviction remains, deciding whether the statute is constitutional would not affect the judgment.
Prejudicial “spillover”
The idea that evidence introduced to prove one charge can improperly influence the jury on other charges. The court noted this concept (via United States v. Simon) but did not decide a spillover claim because Mr. Clements disclaimed it and did not preserve an evidentiary objection.
Plain-error review
A limited appellate safety valve for unpreserved errors. The court indicated it may be available in general (via United States v. Tee), but held it was not in play because Mr. Clements did not ask for it, which constituted waiver (via United States v. Richardson).
Federal Rule of Evidence 413
A rule allowing admission of evidence of other sexual assaults in cases where the defendant is accused of sexual assault. Under United States v. Clay, whether Rule 413 applies depends on the alleged conduct in the case, not merely the title of the charged crime.

5. Conclusion

United States v. Clements crystallizes a procedural limitation with significant practical bite: when a count is dismissed after trial and produces no conviction or sentence, the defendant generally lacks standing to appeal the pretrial denial of a motion to dismiss that count, because any constitutional ruling would be advisory and non-redressive. The opinion also reinforces two practice-driven lessons: (1) evidentiary prejudice must be pursued through preserved evidentiary challenges (or expressly requested plain-error review), and (2) in the Tenth Circuit, certain recurring merits challenges—such as the felon-in-possession Second Amendment claim and the scope of Rule 413—are governed by controlling circuit precedent (Vincent v. Bondi and United States v. Clay).
