Court-Martial Trial Practice Blog
On March 25, 2026, the United States Army Court of Criminal Appeals issued its decision in United States v. Williams-Clark (ARMY 20230185). The court set aside a sexual assault conviction — one that carried a two-year confinement term — not on the merits, but because the verdict itself was fatally ambiguous. The military judge convicted Private Williams-Clark of sexual assault without consent while simultaneously acquitting him of sexual assault when the victim was incapable of consenting. Both specifications covered the same day, the same location, and the same victim — but two separate sexual acts.
The court could not determine which act formed the basis of the conviction. That uncertainty, the court held, made meaningful appellate review impossible. The conviction had to go.
What Actually Happened at Trial
The government charged Williams-Clark with two specifications concerning the same victim on the same night: sexual assault by committing a sexual act without consent, and sexual assault by committing a sexual act when the victim was incapable of consenting due to alcohol. The evidence at trial described two distinct sexual encounters separated by a break — both parties left the room and returned separately before the second incident.
The military judge convicted on the without-consent specification and acquitted on the incapable-of-consenting specification. She made no special findings explaining her reasoning. Neither party had requested them.
That silence created the problem. The appellate court faced an impossible question: which of the two sexual acts did the conviction actually rest on?
“We do not know of which act or acts appellant was found guilty and of which he was found not guilty.”
The Core Legal Distinction: Ambiguous Verdicts vs. General Verdicts
This case turns on a distinction that matters enormously in military appellate practice — and that practitioners and servicemembers alike frequently misunderstand.
Two Doctrines, One Critical Difference
When a single specification charges conduct that could be committed by multiple means, a court can affirm the conviction if the evidence supports at least one of those means beyond a reasonable doubt. The uncertainty is about how the accused committed the offense — not which act he committed.
When the fact-finder both convicts and acquits on distinct acts — and it’s impossible to know which act underlies the guilty finding — the verdict is fatally ambiguous. Affirming it risks upholding a conviction for conduct the fact-finder already acquitted.
The government argued the general verdict rule should save the conviction, pointing to United States v. Nicola, 78 M.J. 223 (C.A.A.F.), where the court affirmed an indecent viewing conviction even though evidence of two viewings — in a barracks room and a shower — was presented at trial. In Nicola, there was one specification and multiple potential factual bases for it. The appellate court could affirm if either theory held up.
Williams-Clark is different. Here the government charged two separate specifications, the military judge returned both a guilty finding and a not guilty finding, and those findings covered two acts that both parties agreed were legally distinct. The parallel acquittal is the critical fact. Once a fact-finder acquits on an incident, double jeopardy principles bar any reviewing court from rehearing that incident. An appellate court that affirms without knowing which act underlies the conviction risks doing exactly that.
Why the Parallel Acquittal Changes Everything
The Walters–Wilson line of cases, which the court applied here, draws a sharp line: it is one thing to have uncertainty about how an accused committed a single charged offense; it is something else entirely to have uncertainty about which incident a mixed guilty/not-guilty verdict actually attaches to.
In United States v. Wilson, 67 M.J. 424 (C.A.A.F. 2009), evidence of two rape incidents — one in a bedroom, one in a bathroom — was presented at trial. The military judge acquitted on “divers occasions” and convicted on one occasion, but never identified which. The Court of Appeals for the Armed Forces held that verdict fatally ambiguous. The Williams-Clark court found the parallel directly on point: two separately chargeable sexual acts, charged as distinct specifications, producing both a guilty and a not guilty finding. That structure, not the label on the specification, triggers the ambiguous verdict doctrine.
The Government’s Shifting Theory — And Why It Mattered
The court also noted something damaging about the government’s position on appeal: it kept changing. At trial, the government argued both sexual acts amounted to a single continuing transaction. On appeal, the government first argued only the first act was legally sufficient to sustain a without-consent conviction under United States v. Mendoza — making the verdict unambiguous. Then, at oral argument, the government reversed course entirely, arguing a recent CAAF decision (United States v. Moore, C.A.A.F. Feb. 13, 2026) meant either act could sustain the conviction, and the general verdict rule should apply.
The court drew a direct line between the government’s instability and the accused’s due process rights. Williams-Clark had a constitutional right to know which offense and which legal theory he stood convicted of. If the government — with full access to the record and unlimited appellate resources — could not maintain a consistent theory across its own briefs, the court asked how the appellant could possibly have known what he faced.
What This Means for Servicemembers
Williams-Clark reinforces several lessons that apply well beyond this particular case.
Charge structure creates appellate risk for the government. When prosecutors charge multiple specifications covering legally distinct acts arising from the same incident, a mixed verdict — guilty on one, not guilty on another — can generate fatal ambiguity. Defense counsel who anticipate this at trial and preserve the issue on the record give their clients a powerful appellate argument.
Special findings requests matter. Neither party in Williams-Clark requested special findings from the military judge. Had the judge articulated which act she convicted on, the ambiguity disappears and the general verdict rule likely controls. The absence of those findings turned a potential affirmance into a dismissal. Experienced trial defense counsel know when to ask.
The appellate landscape shifts — and so does the analysis. The government’s reliance on Moore, decided just six weeks before oral argument, illustrates how rapidly the legal framework in UCMJ Article 120 cases continues to evolve. What prosecutors believed was settled law at the time of trial may face a fundamentally different appellate environment years later.
Dismissal — not just reversal — is available. The court did not remand for a new trial on the sexual assault specification. It dismissed it entirely. That distinction matters enormously for anyone weighing whether to pursue an appeal.
The Result
The court set aside the sexual assault conviction and dismissed that specification. It affirmed the rape conviction and reduced the sentence from seven years’ confinement to five — the term the military judge imposed for the rape alone. The dishonorable discharge stands.
Two years of confinement, gone. Not because of new evidence or a legal change of heart on the underlying conduct — but because the verdict was too uncertain to survive appellate scrutiny.
