When a command takes an unusually long time to investigate, prefer, refer, or bring charges to trial, a service member may reasonably ask whether the delay itself is unlawful. In the military justice system, repeated or prolonged delay in processing charges can violate a service member’s rights, but the analysis is not as simple as counting days. Several overlapping protections apply, each with its own trigger and standard, and only some of them sound in due process. Whether delay rises to a violation, and what remedy follows, depends on which protection is invoked and on the specific facts. The relevant frameworks are the speedy-trial rule in Rule for Courts-Martial 707, the statutory diligence command of Article 10 of the Uniform Code of Military Justice, and the constitutional due-process and Sixth Amendment speedy-trial guarantees.
The 120-day rule under R.C.M. 707
The most concrete protection is Rule for Courts-Martial 707, which generally requires that an accused be brought to trial within 120 days. The clock begins on the earlier of the preferral of charges, the imposition of certain pretrial restraint such as restriction, arrest, or confinement, or entry on active duty for the offense. The day of arraignment is counted; the triggering day is not. Periods of defense-requested or otherwise excludable delay do not count against the government. When the 120-day limit is exceeded without sufficient excludable time, dismissal is the remedy, although that dismissal is usually without prejudice, meaning the government can refile. Importantly, R.C.M. 707 generally measures the period leading to trial; it does not, by its own terms, police every administrative delay that occurs before the clock starts.
Article 10’s reasonable-diligence standard
Article 10 of the UCMJ provides a more demanding protection, but it is triggered only when the accused has been placed in pretrial arrest or confinement. Article 10 directs that, once a member is restrained, immediate steps be taken to inform the member of the offense and either to try the member or to dismiss the charges and release the member. Courts have interpreted this to require reasonable diligence in bringing the case to trial. Reasonable diligence does not mean constant motion, and short periods of inactivity are not necessarily fatal to an otherwise active prosecution. But Article 10 is more protective than R.C.M. 707, and meeting the 120-day rule does not by itself prove that the government exercised the reasonable diligence Article 10 demands. For a …
