The short answer is that an Article 32 preliminary hearing is not the right forum for litigating and resolving discovery violations, but a defense team can and often does note discovery problems on the record so they can be pursued later before a military judge. Understanding why requires looking at what the modern Article 32 hearing is designed to do and, just as importantly, what it is not designed to do.
The Article 32 preliminary hearing changed substantially after Congress amended the governing statute. It is no longer the broad investigative proceeding it once was. The hearing officer does not run a mini-trial, does not rule on the admissibility of evidence as a trial judge would, and does not grant trial-style relief. That narrowed mission directly shapes how discovery complaints can be handled.
The Limited Purpose of the Hearing
By statute and under Rule for Courts-Martial 405, the Article 32 preliminary hearing is confined to a few specific determinations. The preliminary hearing officer examines whether each specification states 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 offenses and the accused, and what disposition the officer recommends. Everything that happens at the hearing is supposed to serve those limited questions.
Notably, discovery is not one of the recognized purposes of the hearing. The rules and the supporting guidance are explicit that the preliminary hearing is not intended to serve as a vehicle for discovery and is not meant to perfect the government’s case or provide the full confrontation rights that attach at trial. Because of that design, the hearing officer lacks the authority to order the government to produce material, to sanction the government for failing to disclose, or to exclude evidence as a remedy.
Why Discovery Disputes Belong Before the Military Judge
The authority to compel discovery and to remedy discovery violations rests with the military judge once charges are referred to a court-martial. After referral, the defense can file motions to compel discovery and motions for appropriate relief, and the judge can order production, continue proceedings, exclude evidence, or fashion other remedies depending on the seriousness of the violation. None of those powers exists at the preliminary hearing stage, where there is no military judge presiding and no trial-level docket.
This division of labor is deliberate. The preliminary hearing is a screening step that asks whether the case should move forward, not an adversarial contest over the full evidentiary record. Discovery obligations are real and enforceable, but the enforcement mechanism activates at the court-martial, not at the Article 32.
What the Defense Can Still Do at the Hearing
The fact that the hearing officer cannot resolve a discovery violation does not mean discovery is irrelevant to the Article 32. Defense counsel have several productive options.
First, counsel can request relevant evidence before and during the hearing. The defense may ask the hearing officer to consider specific documents or witnesses that bear on probable cause and disposition. If the government has not produced something the defense believes is necessary for the hearing officer to make an informed recommendation, counsel can say so on the record.
Second, counsel can make a clear record of the deficiency. Articulating, on the record, what was requested, what was withheld, and why it matters preserves the issue and creates a contemporaneous account that later motions practice can build upon. A well-documented record can also influence the hearing officer’s recommendation, since the officer is asked to advise on how the case should be disposed of.
Third, counsel can use any disclosed material to challenge probable cause and to argue for a favorable disposition recommendation. While the hearing officer cannot punish a discovery failure, the officer can weigh the strength of the evidence that the government actually presents and can recommend against referral or recommend a lesser disposition.
The Practical Effect on Strategy
Experienced defense counsel treat the Article 32 less as a place to win discovery fights and more as an opportunity to learn the contours of the government’s case and to lay groundwork. Even though the proceeding is no longer a discovery tool by design, the hearing frequently reveals which witnesses the government intends to rely on, how the evidence is organized, and where the proof is thin. Counsel can capture all of that for use in post-referral motions.
When a genuine disclosure problem surfaces, the disciplined approach is to flag it precisely, request what is needed for the limited purposes of the hearing, and reserve the substantive fight for the military judge. Raising the issue prematurely as if it were a trial motion will not produce a remedy, because the hearing officer has no remedial authority to grant one.
A Note on Supplementary Submissions
The rules also allow the parties and any named victim to submit additional information they consider relevant to the convening authority’s disposition decision. This channel gives the defense another way to bring the existence of missing or problematic discovery to the attention of the official who decides whether to refer charges, even though it is not a formal discovery remedy.
Conclusion
Discovery violations can be mentioned and documented during an Article 32 hearing, but they cannot be litigated to a resolution there. The preliminary hearing exists to test probable cause, confirm jurisdiction, examine the form of the charges, and recommend a disposition. It is not a discovery proceeding, and the hearing officer has no power to compel production or impose sanctions. The correct path is to preserve the issue at the hearing through a careful record and supplementary submissions, then pursue compulsion and remedies through motions before the military judge after the case is referred to a court-martial. Service members who suspect the government is withholding evidence should raise it with their defense counsel early so the record is built at every available stage.
