The Article 32 hearing is one of the most misunderstood stages in the military justice process. Service members often expect it to function like a full trial, while others assume it is a formality the government can skip. Neither view is accurate. Understanding what the proceeding is actually designed to accomplish helps an accused and their counsel use it effectively rather than treating it as a procedural box to check.
The Core Function: A Probable Cause Screen Before General Court-Martial
The primary purpose of an Article 32 hearing is to serve as a probable cause screening before charges may be referred to a general court-martial. Article 32 of the Uniform Code of Military Justice, codified at 10 U.S.C. 832, calls the proceeding a “preliminary hearing.” Its central question is whether there is probable cause to believe that the accused committed the offense charged. Probable cause is a relatively low threshold. It asks whether there is a reasonable basis to believe an offense occurred, not whether the government can prove guilt beyond a reasonable doubt.
This screening function matters because a general court-martial is the most serious forum in military justice, capable of imposing the harshest authorized punishments, including, for certain offenses, confinement for many years. Article 32 places an independent check between the act of preferring charges and the decision to send a service member to that forum.
What the Statute Actually Requires the Hearing to Determine
The statute is precise about the hearing’s scope. Under 10 U.S.C. 832(a), the purpose of the preliminary hearing is limited to determining four things: whether the specification alleges an offense under the UCMJ; whether there is probable cause to believe the accused committed the offense charged; whether the convening authority has court-martial jurisdiction over the accused and the offense; and a recommendation as to the disposition that should be made of the case.
These four points define both what the hearing is for and what it is not for. The hearing tests the legal sufficiency of the charges, the factual basis for them, the jurisdictional reach of the command, and the appropriate path forward. The preliminary hearing officer who conducts it forwards findings and a recommendation, but the final referral decision rests with the convening authority, who is not bound by the recommendation.
How the 2019 Changes Narrowed the Purpose
Before 2019, the Article 32 proceeding was often called an “investigation,” and many practitioners treated it as a broad discovery tool and a chance to cross-examine the government’s witnesses at length. Amendments stemming from the National Defense Authorization Act for Fiscal Year 2016, implemented through changes to the Rules for Courts-Martial that took effect on January 1, 2019, deliberately refocused the proceeding. The current law renames it a preliminary hearing and centers it on the probable cause determination rather than open-ended fact gathering.
One practical consequence is that discovery is no longer an authorized purpose of the hearing. A second is that the alleged victim of an offense cannot be compelled to testify, and a victim who declines to testify is deemed not available for purposes of the hearing. These changes mean that the modern Article 32 hearing is a leaner, more focused gatekeeping step than its predecessor.
When the Hearing Is Required and When It Is Not
The Article 32 preliminary hearing is required only before referral of charges to a general court-martial. It is not required for special courts-martial or summary courts-martial. An accused may also waive the hearing in writing, and the government may proceed without it if the convening authority determines a hearing is not required following a waiver. Because the hearing is tied specifically to the general court-martial track, its existence in a given case signals that the command is contemplating the most serious form of prosecution.
Why the Purpose Still Matters to the Defense
Even though the probable cause standard is low and the hearing officer only recommends rather than decides, the proceeding carries real strategic value. It is often the first opportunity for the defense to see the shape of the government’s case, to test the strength of available evidence, to raise legal defects in the charges, and to argue for a disposition short of general court-martial. A persuasive showing can lead the preliminary hearing officer to recommend dismissal of weak specifications or a lesser forum, and that recommendation can influence the convening authority even though it is not binding.
In short, the primary purpose of an Article 32 hearing under the UCMJ is to determine, through an impartial officer, whether probable cause and jurisdiction exist to justify sending a service member to a general court-martial, and to recommend how the case should be handled. It is a gatekeeping safeguard rather than a trial, and understanding that distinction is essential to using it well.

Military law also changes over time.
