Long before a court-martial reaches the question of guilt, the defense can attack the charges themselves. One of the most important early tools is a motion challenging whether the charges and specifications are legally sufficient, meaning whether they actually allege a punishable offense and whether they are framed properly enough for the accused to defend against them. The Rules for Courts-Martial not only permit such challenges before arraignment, they often require certain objections to be raised at that early stage or risk being lost.
What legal sufficiency means in this context
A challenge to the legal sufficiency of charges is not a trial on the facts. It does not ask whether the accused did the act; it asks whether the document charging him states a crime at all. The central question is whether the specification alleges every element of the offense, expressly or by necessary implication, and whether it gives the accused fair notice of what he must defend against and protection against being tried twice for the same conduct. A specification that omits an element, charges conduct that is not an offense, or is so vague or defective that it substantially misleads the accused is vulnerable to a pretrial motion.
The rules that govern timing
Under the Rules for Courts-Martial, defenses and objections that can be decided without trying the general issue of guilt may be raised before trial, and many of them must be. Generally, motions and objections, including challenges to the form of a specification, must be raised before the plea is entered. Arraignment is the proceeding at which charges are formally presented and the accused is called upon to plead, so the practical rule is that most charging defects must be litigated at or before arraignment. Raising the issue early is not merely strategic; for many objections it is mandatory to avoid forfeiture.
Two grounds that survive even if not raised early
The rules carve out important exceptions for the most fundamental defects. Two grounds are not waived by a failure to raise them before plea. The first is lack of jurisdiction. A court-martial without jurisdiction over the offense or the accused cannot proceed, and that defect can be raised at any time. The second is failure to state an offense. If a specification simply does not allege a crime, that defect is preserved even if the defense did not flag it at the outset. These two categories are treated as so basic that the system refuses to let them slip away through silence.
By contrast, lesser defects in form, such as a specification that is merely imprecise or duplicative but still states an offense, generally must be raised before plea or they are forfeited. A military judge may grant relief from that forfeiture for good cause shown, so a defense that failed to object early can sometimes still be heard if there is a legitimate explanation, but counsel should never count on that grace.
How the motion is litigated
A motion to dismiss for failure to state an offense, or to dismiss a defective specification, is presented to the military judge. The burden of persuasion rests on the moving party, and factual questions necessary to decide the motion are resolved by a preponderance of the evidence. The judge tests the specification against the elements of the charged offense. If the specification fails to allege an element or charges no crime, the proper remedy is dismissal of that specification. If the specification is merely defective in form, the government may be permitted to address the problem, for instance by amendment that does not prejudice the accused, rather than suffering outright dismissal.
It is worth noting how appellate courts treat these defects after the fact. In United States v. Humphries, the Court of Appeals for the Armed Forces held that a defective specification does not amount to structural error requiring automatic reversal, and reviewing courts examine whether the defect actually prejudiced the accused. That appellate posture is a strong reason to raise sufficiency challenges early at the trial level, where dismissal is a live remedy, rather than relying on appeal, where the analysis is more forgiving to the government.
Why early challenges matter strategically
Attacking the charges before arraignment serves several purposes. It can eliminate a charge entirely, narrow the case, or force the government to clarify or re-prefer a specification. It can expose theories that do not actually constitute offenses under the relevant article. It sharpens the issues for trial and pins down exactly what the government must prove. And it preserves the record, ensuring that if the defect persists, the accused has properly raised it. Because some objections are forfeited if not made before plea, the pretrial window is often the only meaningful chance to litigate them on favorable terms.
The bottom line
An accused absolutely can challenge the legal sufficiency of the charges before arraignment, and for most charging defects that early window is the correct and often required time to do it. Two grounds, lack of jurisdiction and failure to state an offense, survive even without an early objection, but waiting carries risk and weakens the available remedy. Because these motions turn on a precise comparison between the specification and the elements of the charged offense, an accused should have experienced military defense counsel review the charge sheet immediately and raise any viable challenge at the earliest opportunity.
