A court-martial conviction moves up a ladder of courts, and each rung does something different. The path runs from the trial record to the service Court of Criminal Appeals, then to the Court of Appeals for the Armed Forces, and in a narrow set of cases to the United States Supreme Court. It is not one appeal that gets re-argued three times. Each court has its own jurisdiction, its own standard of review, and its own question to answer, so it helps to see the climb as three separate gates rather than a single door.
The first rung: the Court of Criminal Appeals #
Each armed service has its own Court of Criminal Appeals, staffed by senior military judges. This is the only level that can look behind the verdict at the evidence itself.
Two features define the gate at this court:
- Automatic review for serious sentences. Review is automatic when the approved sentence includes a punitive discharge (a bad-conduct or dishonorable discharge or a dismissal) or confinement for one year or more. An accused does not have to ask. Under amendments tied to recent National Defense Authorization Acts, lesser cases are now reviewable as well, though through a different and more limited mechanism rather than the full automatic track.
- Factual sufficiency review. Alone among the appellate courts, a Court of Criminal Appeals may weigh the evidence and judge whether the proof actually supports the findings. For offenses committed on or after January 1, 2021, Congress tightened this. The appellant must now make a specific showing of a deficiency in proof, and only then does the court weigh the evidence with appropriate deference to the trial result. The old practice of a fresh, independent reweighing in every case is gone.
This court also reviews legal errors, the appropriateness of the sentence, and matters raised personally by the accused.
The second rung: the Court of Appeals for the Armed Forces #
The Court of Appeals for the Armed Forces, known as the CAAF, sits above all the service courts. It is composed of five civilian judges appointed by the President and confirmed by the Senate to fifteen-year terms, which makes it a civilian check on the military justice system.
The CAAF reviews questions of law, not questions of fact. It does not reweigh evidence or revisit credibility. It examines whether the law was applied correctly, whether constitutional rights were honored, and whether the lower court erred legally. Most cases reach the CAAF by petition, meaning the court chooses which to take, though certain categories, such as death-penalty cases and cases the Judge Advocate General certifies, come up as of right.
The top rung: the Supreme Court #
After the CAAF, a case may go to the United States Supreme Court, but only by a writ of certiorari, and only in cases the CAAF reviewed or acted on. The Supreme Court grants very few such petitions, so for most service members the CAAF is the practical end of the road.
Counsel and the role of trial preservation #
Appellate defense counsel is provided at no cost for the appeal, paralleling the detailed counsel furnished at trial. One thread runs through the whole ladder worth understanding: the courts above the trial generally review issues that were raised below. An objection made and a record built at trial is what gives an appellate court something concrete to examine, while a point never raised may be reviewed only for plain error or treated as forfeited.
What each court answers, in short #
- Court of Criminal Appeals: Did the evidence support the findings, and was there legal or sentencing error? (the only factual-sufficiency gate)
- CAAF: Was the law applied correctly? (legal questions only)
- Supreme Court: A discretionary look by certiorari in a small number of cases.
Each gate is independent, the standards narrow as the case rises, and the chance to reweigh facts exists only at the bottom. None of this predicts an outcome in any particular case. This material is general information about the appellate process, not legal advice. Anyone facing a court-martial should consult a qualified military defense attorney about their situation.
