There is no single fixed number of days between the preferral of charges and an Article 32 preliminary hearing. The timeline is governed by several rules that work together: the requirement that a preliminary hearing precede referral to a general court-martial, a minimum notice period before the hearing, and the overarching speedy trial protections that cap how long the entire process can take. Understanding the sequence is more useful than memorizing a single deadline.
The sequence of pretrial events
A court-martial case moves through defined stages. First, charges are preferred, meaning a person subject to the UCMJ formally swears to the charges under Rule for Courts-Martial 307. Preferral starts the clock for several purposes. Next, for cases headed to a general court-martial, an Article 32 preliminary hearing must be held before the charges can be referred for trial. After the hearing, the preliminary hearing officer prepares a report, and the convening authority decides how to dispose of the case, which may include referral to a general court-martial.
Article 32 of the UCMJ, codified at 10 U.S.C. 832, requires this preliminary hearing before referral to a general court-martial. It is not required before a special court-martial. So the Article 32 step, and its timing, applies specifically to the general court-martial track.
What Article 32 actually requires on timing
Article 32 and Rule for Courts-Martial 405 set the framework for the hearing rather than a rigid countdown from preferral. Two timing features stand out.
First, the accused is entitled to advance notice of the hearing and to disclosure of certain materials before it occurs. The government must provide the defense, in advance of the hearing, the documents and witness information on which the hearing will rely. The rules build in short disclosure windows measured in days around the setting of the hearing date, so that the defense has a meaningful opportunity to prepare.
Second, the hearing must precede referral, but the rules do not impose a uniform fixed interval such as a flat thirty days from preferral to hearing. In practice, the interval varies with the complexity of the case, the availability of witnesses and counsel, the volume of evidence, and any defense requests for delay. Many cases see a hearing within a few weeks to a couple of months after preferral, but that is a function of circumstances, not a statutory mandate.
The real outer boundary: speedy trial
The most concrete timing constraint is the speedy trial rule. Rule for Courts-Martial 707 provides that the accused must be brought to trial within 120 days. That 120-day clock generally runs from 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. Being brought to trial for this purpose means arraignment, the point at which the accused is called upon to enter a plea.
This is the rule that effectively bounds the pretrial timeline, including the Article 32 hearing, because the hearing must occur before referral and referral must occur before arraignment, all within the broader speedy trial window. Certain periods can be excluded from the 120-day count, for example delays attributable to defense requests or other authorized reasons, so the practical deadline can extend beyond a simple calendar count of 120 days.
There are also additional speedy trial protections. Article 10 of the UCMJ imposes a separate obligation of reasonable diligence when the accused is in pretrial confinement, and the Sixth Amendment provides a constitutional speedy trial right. These standards are distinct from the 120-day rule and can apply even when the 120-day rule is satisfied.
Why the timeline varies in practice
Several factors lengthen or shorten the gap between preferral and the Article 32 hearing. Complex cases, including many Article 120 sexual offense cases, often involve forensic evidence, multiple witnesses, and victim coordination, all of which take time. The defense may request a delay to obtain expert assistance, secure witnesses, or review discovery. Witness and counsel availability, deployments, and operational demands also affect scheduling. Each of these can move the hearing date while remaining consistent with the rules, particularly when delays are properly documented and, where required, excluded from the speedy trial calculation.
A note on who controls the process now
For covered serious offenses, including Article 120 offenses committed on or after late December 2023, independent special trial counsel now make key charging and disposition decisions under recent reforms, rather than the traditional convening authority. This affects who drives the case forward but does not change the basic structure that an Article 32 hearing must precede referral to a general court-martial and that the speedy trial clock continues to run.
Practical takeaway
A service member should not expect a precise, predictable number of days between preferral and the Article 32 hearing. Instead, expect a hearing that is scheduled to precede referral, preceded by required advance disclosures, all occurring within the 120-day speedy trial window subject to authorized exclusions. If the case involves pretrial confinement, the diligence requirement of Article 10 adds further pressure to move promptly. Anyone concerned that the process is moving too slowly, or that excludable delay is being misapplied, should raise the issue with defense counsel, who can assert the applicable speedy trial protections.

Military law also changes over time.
