Appeals from courts-martial move through a two-tier system. A service Court of Criminal Appeals reviews the case first, and the United States Court of Appeals for the Armed Forces sits above the service courts as the civilian appellate court for the military justice system. When a case raises an issue that reaches beyond the individual accused, outside organizations sometimes want to weigh in. The question is whether a service member association, advocacy group, or similar organization may file a friend-of-the-court brief in these appeals. The answer is generally yes, but only on the court’s terms, and the threshold issue of military unions deserves its own explanation.
A note on military “unions”
It is important to address the word “union” directly. United States law restricts labor organizing within the armed forces. Federal statute makes it unlawful for a member of the armed forces to enroll in or maintain membership in a military labor organization, and it bars such organizations from certain activities directed at the military. As a practical matter, the kind of collective-bargaining union common in civilian workplaces does not exist for active-duty service members in the way it does elsewhere. What does exist, and exists robustly, is a large ecosystem of service member associations, veterans organizations, professional and bar associations, and public-interest advocacy groups. These are the entities that, in practice, seek to participate as friends of the court. The amicus question therefore turns on the rules governing outside organizations generally, not on any special status for a labor union.
The two ways an amicus brief gets before a military appellate court
Both the service Courts of Criminal Appeals and the Court of Appeals for the Armed Forces have rules of practice that recognize amicus participation. Under those rules, an amicus brief may be filed in one of two ways. The court may invite the brief, or the prospective amicus may file a motion for leave and the court may grant it. There is no automatic right for an outside organization to inject itself into a court-martial appeal. Participation is by invitation or by permission.
The joint rules that govern the service appellate courts make this framework explicit. A brief of an amicus curiae may be filed by invitation of the court or by motion for leave granted by the court. The rules also signal that the privilege is not to be abused. An amicus brief that does not assist the court burdens it, and its filing is not favored. A movant seeking leave is generally expected to state whether the parties consent to the filing, with a narrow exception for a victim filing in the victim’s recognized capacity.
The Court of Appeals for the Armed Forces follows a parallel approach. Its rules allow an amicus brief to be submitted in connection with the matters the court considers, including a petition for grant of review, a petition for extraordinary relief, a writ-appeal petition, a petition for new trial, a certified case, a mandatory review case, or a granted case. As with the service courts, the brief comes in by invitation or by leave, and all requests proceed by written motion that states the relief sought and the grounds for it.
What this means for associations and advocacy groups
A service member association or comparable organization is eligible to seek amicus status under these rules just like any other non-party. The organization does not file a brief as of right. It files a motion for leave, explains its interest in the case and how its brief will help the court, and usually addresses whether the parties consent. If the court agrees that the brief will aid its analysis, it grants leave and the brief becomes part of the record the court may consider. The court may also, on its own, invite a particular organization to brief an issue when it wants outside perspective.
This is not a theoretical possibility. The Court of Appeals for the Armed Forces has accepted amicus briefs from outside organizations in cases presenting significant legal questions, and its public docket reflects amici curiae participating in argued cases. Organizations with relevant expertise, such as bar groups, legal-advocacy organizations, and associations concerned with the rights of service members, have appeared in this capacity.
How a court evaluates the request
Because filing is by leave and disfavored when it does not assist the court, an organization improves its chances by showing genuine added value. A persuasive motion typically explains who the organization is, why it has a concrete interest in the outcome, and what unique perspective, expertise, or set of considerations the brief will bring that the parties themselves may not fully develop. A brief that merely repeats a party’s arguments offers little and is more likely to be seen as a burden. A brief that supplies a broader institutional context, addresses systemic consequences, or brings specialized knowledge to bear is far more likely to be welcomed.
Timing and format also matter. The rules tie amicus participation to specific stages of the proceeding, so an organization must move at the appropriate point, whether that is before the court acts on a petition or while a granted case is being briefed. Counsel for the organization should consult the current rules of the specific court, because the service appellate courts and the Court of Appeals for the Armed Forces periodically revise their rules of practice.
The bottom line
Service member associations and advocacy organizations can participate as amici in court-martial appeals, both at the service Courts of Criminal Appeals and at the Court of Appeals for the Armed Forces. They do so either because the court invites them or because they move for leave and the court grants it. There is no special amicus channel for a “union” in the labor sense, since federal law constrains military labor organizing, but the broad community of service member and public-interest organizations may seek to be heard through the ordinary amicus process. The decisive factor is not the identity of the organization so much as whether its brief will genuinely help the court decide the issues before it.
