An Article 32 preliminary hearing is the gateway between an investigation and a general court-martial. Before serious charges can be referred to the most powerful level of military trial, the government must clear this procedural step. Article 32 of the Uniform Code of Military Justice sets the statutory requirement, but the day-to-day mechanics of how the hearing actually runs come almost entirely from the Manual for Courts-Martial. Understanding that division of labor explains why the Manual matters so much.
The relationship between the statute and the Manual
Article 32 of the UCMJ is the law passed by Congress. It establishes that a preliminary hearing must be held before charges may be referred to a general court-martial, and it sets the basic purpose of that hearing. But a statute alone cannot govern every detail of a proceeding. That is where the Manual for Courts-Martial enters.
The Manual is the executive branch’s implementation of the UCMJ, issued by the President. Within the Manual, the Rules for Courts-Martial, commonly cited as RCM, translate the statute into operating procedure. Rule for Courts-Martial 405 is the central provision governing Article 32 preliminary hearings. When practitioners ask how an Article 32 actually works, the answer lives in RCM 405 and the surrounding rules, all found inside the Manual.
Defining the purpose and scope of the hearing
Following the reforms that took effect after the Military Justice Act of 2016, the Article 32 proceeding is a preliminary hearing rather than the broad investigation it once was. The Manual reflects this narrowed purpose. Under RCM 405, the preliminary hearing officer is tasked with determining a defined set of questions rather than conducting a free-ranging inquiry.
Specifically, the Manual directs the preliminary hearing officer to determine whether each specification alleges an offense, whether there is probable cause to believe the accused committed the charged offenses, whether the convening authority has court-martial jurisdiction over the accused and the offenses, and what disposition should be recommended. By limiting the inquiry to these points, the Manual prevents the hearing from becoming a full discovery deposition or a dress rehearsal of the trial.
Establishing the role of the preliminary hearing officer
The Manual defines who runs the hearing and what that person may and may not do. The preliminary hearing officer functions as an impartial evaluator. Under the rules, the officer weighs the credibility of the evidence presented by both sides and reaches the conclusions the Manual requires.
The Manual also clarifies the officer’s authority over evidence. The preliminary hearing officer may consider forms of evidence that would not necessarily be admissible at a court-martial, so long as the evidence is relevant to the limited purposes of Article 32 and RCM 405. This flexible evidentiary posture is a deliberate feature of the rule, reflecting that a preliminary hearing tests probable cause rather than guilt beyond a reasonable doubt.
Governing the rights of the accused
One of the most important functions the Manual serves is to spell out the accused’s procedural rights at the hearing. RCM 405 requires that the proceeding begin with the preliminary hearing officer informing the accused of the rights available during the hearing.
Those rights, as structured by the Manual, include the right to be represented by counsel, the right to be present, the right to cross-examine witnesses who appear, and the right to present matters in defense and mitigation that are relevant to the limited scope of the hearing. The Manual frames these rights against the reduced purpose of the modern hearing, which is part of why the scope of witness production and cross-examination at Article 32 is narrower than it is at trial.
Controlling evidence and witness production
The Manual also governs how evidence and witnesses come before the preliminary hearing officer. Because the post-2016 hearing focuses on probable cause, the rules give the government flexibility to present its case through documentary evidence and sworn statements rather than requiring live testimony for every point. The Manual sets the framework that the preliminary hearing officer uses to decide what witnesses and evidence are relevant to the issues the officer must resolve.
This evidentiary structure inside the Manual is what shapes the practical experience of an Article 32 today. A defense attorney preparing for the hearing is preparing within the boundaries that RCM 405 draws.
Directing the report and recommendation
After the hearing concludes, the Manual dictates what the preliminary hearing officer must produce. The officer prepares a report that addresses the required determinations, including whether probable cause exists, whether jurisdiction is proper, and what disposition the officer recommends. The Manual prescribes the form and content of this report so that the convening authority receives a consistent and complete document on which to base a referral decision.
The recommendation is not binding. The convening authority retains the discretion to refer charges, to dispose of them at a lower level, or to take other action. But the report generated under the Manual’s rules is a key input into that decision and creates a record of the proceeding.
Why the Manual’s role matters in practice
For an accused service member and defense counsel, the Manual is the operating manual in the most literal sense. It tells everyone in the room what the hearing is for, who controls it, what evidence may be considered, what rights the accused holds, and what the end product must contain. Article 32 of the UCMJ supplies the requirement that a preliminary hearing occur, but it is the Manual for Courts-Martial, principally through RCM 405, that gives the hearing its shape.
That is why experienced military justice practitioners read the statute and the Manual together. The statute answers whether a preliminary hearing is required. The Manual answers how it is conducted, and it is in those procedural details that defense opportunities and government obligations are found. Anyone facing referral to a general court-martial should understand that the protections and limits of the Article 32 process flow from the Manual, and should work with qualified counsel who knows how to use RCM 405 to test the government’s case at this early and important stage.

Military law also changes over time. The Military Justice Act of 2016 (effective January 1, 2019) and subsequent National Defense Authorization Acts renumbered and rewrote many punitive articles, revised the Article 32 preliminary hearing, and altered sentencing, clemency, and appellate procedures. Statutes, regulations, executive orders, the Manual for Courts-Martial, and decisions of the service Courts of Criminal Appeals and the Court of Appeals for the Armed Forces may have been amended, superseded, or reinterpreted after this article was written, and article numbers or procedures cited here may have changed.
