When charges head toward a general court-martial, the accused first encounters the government’s case at the Article 32 preliminary hearing. Defense counsel naturally want to see the evidence before that hearing. Understanding what the government must produce, what it need not produce, and what happens when it withholds something requires separating two different bodies of law: the rules that govern the preliminary hearing itself and the constitutional duty to disclose favorable evidence.
The preliminary hearing is narrower than many expect
The Article 32 hearing was significantly changed by reforms that took effect in December 2014. It is now a preliminary hearing whose purpose is limited to determining whether there is probable cause to believe an offense was committed and that the accused committed it, whether the convening authority has jurisdiction, and whether the charges are in the proper form, along with a recommendation on disposition. It is no longer the broad discovery device that the older pretrial investigation once functioned as in practice.
This matters for the disclosure question. Because the hearing is narrow, the government’s obligation to produce evidence for the hearing is correspondingly limited. Rule for Courts-Martial 405 sets out the process. The defense may request that the government produce relevant witnesses and documentary evidence under the government’s control. Trial counsel must respond regarding whether the requested evidence is relevant, not cumulative, and necessary for the limited purpose of the hearing. If the preliminary hearing officer finds requested evidence relevant and necessary but it is not under government control, the officer may direct counsel to seek a pre-referral investigative subpoena.
So a defense complaint that the government did not hand over its entire case before the Article 32 hearing often runs into the reality that broad pre-hearing discovery is not what the modern hearing provides.
Brady obligations apply regardless of the hearing’s scope
The narrow scope of the preliminary hearing does not eliminate the constitutional duty to disclose favorable evidence. Under Brady v. Maryland, 373 U.S. 83 (1963), the Due Process Clause requires the prosecution to disclose evidence that is favorable to the accused and material to guilt or punishment. This obligation reaches exculpatory evidence and impeachment evidence, and it is a continuing duty that does not depend on a defense request.
In the military system, this constitutional duty is reinforced by the discovery rules in Rule for Courts-Martial 701, which require trial counsel to disclose evidence favorable to the defense. Together, the constitutional and regulatory obligations mean the government cannot simply sit on evidence that undercuts its own case.
The difference between non-production and suppression
It is important to distinguish two situations. The first is a refusal or failure to produce evidence for the limited purposes of the Article 32 hearing. When the preliminary hearing officer determines that requested evidence is relevant and necessary, the officer may direct the government to seek it. If trial counsel declines, counsel must explain the reasons in writing, and the unsuccessful effort is noted in the hearing report. The hearing itself is generally not delayed unreasonably for evidence that cannot be obtained.
The second situation is genuine suppression of favorable, material evidence. That is a due process problem, not merely a hearing-management issue. If the government withholds exculpatory or impeachment evidence, the remedy is not limited to the preliminary hearing stage. The accused may raise the violation at trial through a motion to compel discovery or a motion for appropriate relief, and a proven suppression of material favorable evidence can support reversal on appeal under Brady principles.
Remedies and consequences
When the government fails to disclose evidence it was required to disclose, several outcomes are possible depending on the nature and timing of the failure.
If the issue arises at the preliminary hearing, the defense can object on the record, request that the hearing officer direct production, and have any refusal documented in the report that goes to the convening authority. Because the hearing officer makes a disposition recommendation, a documented failure to produce can influence how the case proceeds.
If the issue involves favorable material evidence and surfaces before or during trial, the military judge may order disclosure, grant a continuance, exclude evidence the government tried to use unfairly, or in serious cases grant relief that affects the charges. If a Brady violation is discovered only after trial, the materiality standard governs: relief is warranted where there is a reasonable probability that disclosure would have produced a different result.
Practical guidance
The practical lesson is to match the complaint to the right rule. A demand for the government’s full case file before the Article 32 hearing will often be denied because the modern preliminary hearing is not designed for that. A demand for specific favorable evidence stands on much firmer ground, because the duty to disclose exculpatory and impeachment material does not bend to the hearing’s limited scope.
Defense counsel should make specific, documented requests, preserve any government refusal on the record, and renew discovery efforts as the case moves toward trial where the broader discovery rules apply. Because the available remedy depends heavily on what was withheld, why, and when the withholding is discovered, an accused who believes the government is concealing evidence should raise the concern promptly and in writing so the issue is preserved for every stage of the process.
