When investigators seize evidence through what the defense believes was an illegal search, the instinct is to attack that evidence at the earliest possible moment. In a court-martial, the first formal adversarial proceeding is usually the Article 32 preliminary hearing. So a natural question arises: can the defense move to suppress unlawfully obtained evidence right there at the Article 32, before charges are even referred to trial? The short answer is no, not as a suppression motion. The longer answer explains why, and what the defense can realistically do with a search problem at that stage.
What an Article 32 hearing is for
Article 32 of the Uniform Code of Military Justice, implemented by Rule for Courts-Martial (RCM) 405, requires a preliminary hearing before charges can be referred to a general court-martial, unless the accused waives it. Since the procedures were overhauled effective January 1, 2019, the hearing has a deliberately limited purpose. It exists to examine 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 offense and the accused, and to recommend a disposition of the case.
The Court of Appeals for the Armed Forces has emphasized that the Article 32 hearing, while important, is not part of the court-martial itself. In United States v. Davis, 64 M.J. 445, the court described the preliminary investigation as a predicate to referral rather than a trial on the merits. The hearing functions, as courts have put it, as a bulwark against baseless charges. It is a screening mechanism, not a forum for resolving the admissibility of evidence.
The Military Rules of Evidence mostly do not apply
The reason a suppression motion does not fit the Article 32 stage is structural. The Military Rules of Evidence, which contain the search-and-seizure exclusionary provisions in Military Rule of Evidence 311 and the related rules, generally do not apply at the preliminary hearing. Under RCM 405(i), only a narrow set of evidentiary rules carries over: the rules on privileges, the rape-shield protections of Military Rule of Evidence 412, and the rules governing self-incrimination warnings and interrogation.
Because the broader exclusionary framework is switched off, the preliminary hearing officer has no authority to decide that evidence was the product of an unlawful search and to exclude it on that basis. The preliminary hearing officer can hear and consider evidence that might later be ruled inadmissible at trial. Probable cause may rest on material that a military judge could eventually suppress. That is by design: the screening question is whether there is enough to send the case forward, not whether every piece of evidence would survive a constitutional challenge at trial.
Where suppression actually happens
The proper forum for challenging an unlawful search is a motion to suppress litigated before the military judge after referral. At that point the full Military Rules of Evidence apply, the defense can invoke Military Rule of Evidence 311 and the Fourth Amendment, the government bears its burden on the lawfulness of the search, and the judge can hold an evidentiary hearing, take testimony, and rule on admissibility. If the judge suppresses the evidence, it cannot be used in the government’s case-in-chief at trial. This is the structured, recorded process designed to resolve search-and-seizure disputes, and it occurs once the case has moved past the preliminary hearing stage.
What the defense can do with a search issue at the Article 32
The fact that a formal suppression motion does not belong at the Article 32 does not make the search problem useless there. A skilled defense can still put the illegality to work in ways that fit the hearing’s purpose.
First, the defense can argue probable cause. The preliminary hearing officer must assess whether probable cause exists to believe the accused committed the offense. If the questionable search produced the core evidence, the defense can argue that, stripped of credibility or weight, the government’s showing is thin, or can highlight the circumstances of the seizure to undercut reliability. The officer is permitted to weigh the evidence presented.
Second, the defense can develop the factual record. Article 32 gives the accused the right to be present, to be represented by counsel, to cross-examine witnesses the government produces, and to present matters in defense and mitigation, rights the Court of Appeals for the Armed Forces recognized in United States v. Garcia, 59 M.J. 447. Cross-examining the agent who conducted the search can lock in testimony about how, when, and under what authority the search occurred. That testimony can later support the trial-stage suppression motion and can expose inconsistencies before the witness has had a chance to refine the account.
Third, the defense can shape disposition. The preliminary hearing officer recommends what should happen with the case. Demonstrating that the central evidence is legally vulnerable can support a recommendation against referral to a general court-martial, or in favor of a lesser disposition, even though the officer cannot formally suppress anything.
A note on scope and the privileged exceptions
It is worth distinguishing search-and-seizure issues from the rules that do apply. Because privileges, the rape-shield rule, and self-incrimination protections remain in force at the hearing, a statement taken in violation of Article 31 warnings or a communication protected by privilege may be handled differently than physical evidence from a search. But the classic Fourth Amendment exclusionary remedy for an unlawful search is not among the rules that operate at Article 32. Counsel should not conflate the two categories.
Bottom line
Evidence from an allegedly unlawful search cannot be suppressed at an Article 32 preliminary hearing, because that proceeding is a probable-cause screening governed by RCM 405, where most of the Military Rules of Evidence, including the search-and-seizure exclusionary rule, do not apply. The right place to challenge an illegal search is a motion to suppress before the military judge after referral, where the full evidentiary rules govern. The smart approach is to use the Article 32 to attack probable cause, build a clean factual record through cross-examination of the searching agents, and shape the disposition recommendation, while preserving the formal suppression fight for trial.
