In a court-martial sentenced by members, the military judge instructs the panel before it deliberates on punishment. Those instructions shape what the members believe they are permitted to impose. When the instructions leave out a punishment option that was legally available, the members may sentence the accused without understanding the full range of choices the law allows. This article explains why that omission is an error, how an accused preserves and raises it, and what relief is realistically available.
What the sentencing instructions must cover
Rule for Courts-Martial (RCM) 1005 governs instructions on sentence. The military judge must instruct the members on the matters necessary for them to reach a proper sentence. This includes the maximum authorized punishment that may be adjudged and the procedures for deliberating and voting on a sentence. The purpose is to give the panel an accurate legal picture so that its decision rests on a correct understanding of its authority.
The members are entitled to know not only the ceiling on punishment but also the components and lesser measures available to them. When a category of punishment that the law permits is omitted from the instructions, the panel may wrongly believe it must choose from a narrower set than the law actually provides. That can prejudice the accused, because a member who is unaware that a less severe option exists cannot consider it.
Why an omitted option is an instructional error
An incomplete instruction on the available punishments is a form of instructional error. Military appellate courts treat the failure to give a required or correctly framed instruction as legal error subject to review. The core concern is reliability. A sentence is supposed to reflect the panel’s reasoned judgment across the full lawful range. If the instructions truncate that range, the resulting sentence may not reflect what the members would have chosen had they understood their actual options.
Preserving the error: objection and requested instruction
The way an accused responds at trial strongly affects the standard of review on appeal. The defense should object to the omission and, where appropriate, request the specific instruction that was left out. The objection or request must signal to the military judge, clearly enough to allow correction, that an instruction is missing or wrong. When the defense properly preserves the issue this way, the error is reviewed under a more favorable standard, and the government generally bears the burden of showing that the error did not affect the sentence.
If the defense does not object, the issue is ordinarily reviewed for plain error. Under that standard the accused must show that there was error, that it was clear or obvious, and that it materially prejudiced a substantial right. Plain error is a harder road, which is why raising the problem at trial is so important. The simplest and most effective remedy for an omitted instruction is to obtain the correct instruction before the panel deliberates, so counsel should be alert to the full range of punishments and request any that the proposed instructions overlook.
Relief at the trial level
The first opportunity for relief is at trial. If the omission is caught before the members deliberate, the military judge can correct the instructions and cure the error entirely. If it is identified after a sentence is announced but while the court-martial is still in session, the military judge may take corrective steps, including reinstructing the members and having them deliberate again on sentence. Catching and fixing the problem at trial avoids the uncertainty of appellate review and is by far the cleaner outcome.
Relief on appeal
If the error is not cured at trial, it can be raised on appeal. A general court-martial sentence and many special court-martial sentences are reviewed by a service Court of Criminal Appeals, with further discretionary review available at the Court of Appeals for the Armed Forces. On appeal, the question is whether the instructional error requires relief.
Where the error is preserved, the reviewing court asks whether the omission was harmless. If the court cannot be confident that the members would have reached the same sentence with correct instructions, the typical remedy is to set aside the sentence and authorize a sentence rehearing. A rehearing returns the case for resentencing before a properly instructed panel or military judge, with the findings of guilt left intact. The conviction itself is not disturbed by a purely sentencing instruction error; the relief is directed at the sentence.
In some cases an appellate court may grant relief without a full rehearing by reassessing the sentence itself. Sentence reassessment allows the reviewing court to determine a sentence it is confident the trial-level court would have imposed absent the error, but only when the court can reliably do so. If the error makes such confidence impossible, a rehearing is the appropriate remedy. The choice between reassessment and rehearing depends on how significant the omitted option was and how much it could have changed the outcome.
The role of prejudice
Relief is not automatic. Even a clear instructional omission will not result in a new sentence if the reviewing court concludes the error was harmless, meaning it did not affect the sentence the accused actually received. Where the omitted option was a meaningful alternative that the members realistically might have chosen, the case for prejudice is strong. Where the omitted option would not plausibly have changed the result, a court may find the error harmless and leave the sentence in place. Counsel arguing for relief should connect the missing option concretely to the sentence imposed, showing that an informed panel could have gone lighter.
Practical guidance
The most important lesson is to address the problem before deliberations. Defense counsel should compare the proposed instructions against the full menu of punishments the law authorizes for the offenses of conviction and object to any omission, requesting the specific missing instruction. Doing so both protects the client immediately and secures the more favorable standard of review if the issue ever reaches appeal.
If the error surfaces only after sentencing, it should be preserved in the record and pursued through the post-trial and appellate process. The realistic relief is a corrected sentence, achieved either through a rehearing before a properly instructed sentencing authority or, where the court can do so reliably, through sentence reassessment. Because these issues turn on the precise instructions given and the punishments authorized for the specific charges, a service member who believes the panel was not told about an available punishment should consult experienced military defense counsel to evaluate the record and pursue the right remedy.
