The short answer is that character evidence can sometimes be presented at an Article 32 preliminary hearing, but its usefulness is sharply limited by what the hearing exists to decide. Since the Military Justice Act of 2016 took effect on January 1, 2019, the Article 32 hearing is no longer a broad pretrial investigation. It is a focused proceeding with a narrow purpose, and whether character evidence has any place depends entirely on whether it speaks to that purpose.
What the Article 32 hearing is actually for
Article 32 of the Uniform Code of Military Justice now defines the preliminary hearing’s purposes in a closed list. The preliminary hearing officer is there to determine whether each specification alleges an offense under the UCMJ, whether there is probable cause to believe the accused committed the charged offense, whether the convening authority has court-martial jurisdiction over the accused and the offense, and to recommend a disposition of the case. That is the entire mission. Probable cause is a low evidentiary threshold, requiring only reasonable grounds to believe an offense occurred and that the accused likely committed it. The hearing is not a mini-trial on guilt, and it is not a forum for resolving credibility the way a panel would at trial.
Why scope determines admissibility
Because the hearing exists to test probable cause, disposition, and jurisdiction, evidence is relevant only if it bears on one of those questions. Traditional character evidence offered to prove that the accused is a good person who would not commit the offense, or that the accused has a propensity not to behave that way, generally does not move the probable-cause needle. The preliminary hearing officer is not weighing innocence against guilt; the officer is asking whether reasonable grounds exist to send the case forward. For that reason, defense counsel rarely gain traction by trying to relitigate guilt through reputation or opinion testimony at this stage.
Where character information does have a legitimate role
The picture changes when character information is offered for the disposition recommendation rather than to defeat probable cause. The preliminary hearing officer’s report includes a recommendation on how the case should proceed, which can range from dismissal, to referral to a lower forum such as a special court-martial, to referral to a general court-martial, to administrative or nonjudicial resolution. Information about the accused’s service record, prior good conduct, performance, awards, and rehabilitative potential can be genuinely relevant to that disposition recommendation. The accused has the right to present matters in defense and mitigation relevant to the hearing’s purposes, to make a statement, and to argue for a disposition that serves the accused’s interests. Character and service-record evidence offered in that spirit is appropriate and often the most productive use of the defense’s time at the hearing.
The rules of evidence are mostly relaxed
A common misunderstanding is that the formal Military Rules of Evidence govern an Article 32 hearing. They do not. Under Rule for Courts-Martial 405, the Military Rules of Evidence generally do not apply at the preliminary hearing, with limited exceptions. The exceptions that do apply are the rules concerning self-incrimination and rights warnings (Military Rules of Evidence 301, 302, 303, and 305), the rape-shield rule of Military Rule of Evidence 412(a) as supplemented by the procedures in Rule for Courts-Martial 405, and the privileges in Section V of the rules, subject to certain carve-outs. Because the broader evidentiary rules are relaxed, the preliminary hearing officer may consider materials that would face objections at trial. This relaxed posture means there is no rigid bar on character information being mentioned, but it also means the officer can give such information whatever weight it deserves in light of the limited purpose of the proceeding.
The rape-shield rule still controls
One important limit survives the relaxed-rules framework. Where a sexual offense is charged, Military Rule of Evidence 412 applies through Rule for Courts-Martial 405, and a party who intends to offer evidence covered by that rule must give written notice by motion before the hearing, describing the evidence and explaining why it is admissible. This matters because what is sometimes loosely called “character evidence” about an alleged victim, such as evidence of other sexual behavior or sexual predisposition, is presumptively inadmissible and cannot be backed into through the relaxed-rules door. Unless good cause is shown, evidence offered in violation of the rule’s procedures must be excluded from the hearing.
Practical takeaways
For the accused and defense counsel, the realistic strategy is to treat character information as a disposition tool, not a guilt-phase argument. Presenting evidence of strong service, good conduct, and rehabilitative potential can support a recommendation for a lesser forum or for resolution short of a general court-martial, and that recommendation, while not binding, carries real influence with the convening authority. Trying to win an acquittal-style argument on character at the probable-cause stage usually misreads what the hearing can deliver.
For anyone evaluating the question generally, the accurate summary is this: character evidence is not categorically prohibited at an Article 32 hearing, the formal evidentiary rules that would govern its admission at trial mostly do not apply, and its real value lies in the disposition recommendation rather than in defeating probable cause. Because the strategy depends heavily on the specific charges and the posture of the case, an accused facing an Article 32 hearing should rely on detailed advice from qualified military defense counsel rather than general guidance.

Military law also changes over time.
