Rule for Courts-Martial 707 is the regulatory speedy trial rule in the military justice system. It sits alongside, but is distinct from, the constitutional speedy trial right under the Sixth Amendment and the statutory limits on pretrial confinement under Article 10 of the Uniform Code of Military Justice. When a service member believes the government has taken too long to bring a case to trial, RCM 707 is usually the first and most concrete authority a defense counsel invokes, because it sets a fixed numerical deadline rather than a balancing test.
The 120-Day Clock
RCM 707 requires that an accused be brought to trial within 120 days. The clock starts running from the earliest of several triggering events: the preferral of charges, the imposition of restraint under RCM 304 (such as arrest, restriction, or pretrial confinement), or the entry onto active duty for the purpose of facing court-martial. Because the rule keys off the earliest of these events, the timeline often begins before an accused fully understands that a prosecution is underway.
“Brought to trial” for purposes of the rule means arraignment, not the completion of the trial. Arraignment is the point at which charges are formally read and the accused is called upon to enter pleas. So the government generally satisfies RCM 707 by arraigning the accused within 120 days, even if the actual evidentiary portion of the trial occurs later.
Excludable Delay
The 120-day count is not a simple stopwatch. RCM 707 allows certain periods to be excluded from the calculation. Delays approved by a convening authority before referral, or by a military judge after referral, may be excluded if they are reasonable. Common excludable periods include delays for sanity boards or mental responsibility inquiries, delays to obtain the results of forensic testing, and delays attributable to defense requests for continuances. The party seeking to exclude time generally must show that the delay was justified, and the decision to grant or deny excludable delay is documented in the record so it can be reviewed later.
In some circumstances the clock can reset entirely. If charges are dismissed and later re-preferred, or if there is a substantial break in the proceedings, a new period may begin to run. These reset scenarios are heavily fact-dependent and are a frequent source of litigation, because the government and the defense often disagree about whether a genuine break occurred or whether the dismissal …
