An Article 32 hearing is the preliminary hearing required by Article 32, Uniform Code of Military Justice (10 U.S.C. 832), before charges may be referred to a general court-martial. It is not a trial. Its purpose is narrow: to determine whether the specifications allege offenses under the UCMJ, whether there is probable cause to believe the accused committed those offenses, whether the convening authority has court-martial jurisdiction over the accused and the offenses, and to recommend a disposition for the case. Because the hearing answers those limited questions, the evidence introduced there looks different from the evidence a panel or military judge would later weigh at trial.
Why the rules of evidence matter less here
The single most important thing to understand about Article 32 evidence is that the Military Rules of Evidence generally do not apply to the preliminary hearing. With limited exceptions, such as rules governing privileges and certain protections for victims, the preliminary hearing officer may consider material that would be inadmissible at trial. This is a deliberate feature of the statute, which sets a low probable-cause threshold rather than a beyond-a-reasonable-doubt standard. As a practical consequence, the government can satisfy its burden largely on paper, and much of what is introduced is documentary rather than live testimony.
Documentary and written evidence
In most modern Article 32 hearings, the bulk of the record is documentary. The government commonly presents the charge sheet, sworn and unsworn statements from witnesses, law enforcement reports prepared by military criminal investigative organizations, and forensic or laboratory reports. Photographs, electronic records, message logs, medical records, and command paperwork frequently appear. Because hearsay limits do not bar this material at the preliminary hearing, written statements often stand in for witnesses who do not appear in person.
Witness testimony and cross-examination
Live testimony does occur, but it is more limited than at trial. The accused has the right to cross-examine witnesses who actually testify and to present additional evidence relevant to the determinations the hearing officer must make. The presentation of evidence and the examination of witnesses are confined to matters relevant to probable cause, jurisdiction, and disposition. One significant limitation reflects reforms made by Congress: an alleged victim may decline to testify at the preliminary hearing and cannot be compelled to do so. When a victim does not testify, the hearing officer typically relies on the victim’s prior statements and the investigative record.
Evidence the defense may introduce
Although Article 32 is structured around the government’s burden, the defense is not a passive observer. The accused may cross-examine the government’s witnesses, may call witnesses who are reasonably available, and may offer documents or other matter relevant to the limited issues before the hearing officer. Defense counsel often use the hearing to test the strength of the government’s proof, to lock in witness accounts, and to surface weaknesses in the chain of custody, identification, or jurisdiction. Even though the standard is only probable cause, a well-developed defense presentation can shape the hearing officer’s disposition recommendation.
What the hearing officer produces
The preliminary hearing officer weighs the material presented and prepares a report addressing each required determination, including a recommendation on disposition. That recommendation is not binding on the convening authority, who retains discretion over whether to refer charges. The evidence introduced at Article 32 therefore serves two functions at once: it builds the record on which the probable-cause finding rests, and it informs the command’s eventual referral decision.
How Article 32 evidence differs from trial evidence
The contrast with a court-martial is sharp. At trial, the Military Rules of Evidence govern admissibility, hearsay is generally excluded absent an exception, witnesses ordinarily testify in person and under oath, and the standard of proof is beyond a reasonable doubt. At the Article 32 hearing, written statements substitute for live testimony, hearsay flows freely, and the question is only whether probable cause exists. Understanding that gap helps an accused and counsel calibrate strategy. Material that seems damaging on paper at the preliminary hearing may never be admissible later, and testimony preserved or undermined at Article 32 can carry forward into the trial that follows.
Practical takeaways
For a service member facing a general court-martial, the types of evidence at the Article 32 hearing usually include the charge sheet, investigative reports, sworn and unsworn witness statements, forensic and documentary records, and a smaller amount of live testimony subject to cross-examination. The relaxed evidentiary environment cuts both ways: it lets the government meet a low bar quickly, but it also gives the defense an early, structured opportunity to probe the case before it is referred. Because the hearing officer’s report can influence the disposition decision, the evidence presented at this stage deserves careful attention even though no findings of guilt are made.

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.
