Service members often expect the Article 32 preliminary hearing to be the place where they fight to keep illegally obtained evidence out of their case. It is not. The Article 32 hearing and a motion to suppress are two different proceedings with two different purposes, and understanding the line between them is essential. The short answer is that you generally do not litigate suppression at the Article 32 hearing; you litigate it before the military judge at trial. But what happens at the Article 32 hearing can still shape how a later suppression motion plays out. This article explains both halves of that answer.
The narrow purpose of the Article 32 hearing
The Article 32 preliminary hearing, governed by Article 32 of the Uniform Code of Military Justice and Rule for Courts-Martial 405, exists to screen a case before it can be referred to a general court-martial. Its scope is deliberately limited. The preliminary hearing officer is there to determine whether each specification states an offense, whether there is probable cause to believe the accused committed the charged offenses, whether the court-martial would have jurisdiction, and what disposition the officer recommends.
Nothing in that list is about the admissibility of evidence at trial. The hearing tests whether there is enough to send the case forward, not whether particular evidence was lawfully obtained. That difference is the whole reason suppression is not the business of the Article 32 hearing.
Why suppression is not decided at the Article 32 hearing
A motion to suppress asks a court to exclude evidence because it was obtained in violation of the accused’s rights, for example through an unlawful search, an involuntary statement, or a defective seizure. Resolving such a motion requires the full machinery of the rules of evidence and a judge with authority to make binding admissibility rulings. The Article 32 hearing has neither.
At the preliminary hearing, only a limited set of the Military Rules of Evidence applies, principally the rules on privileges, the rape-shield protections, and the privilege against self-incrimination. The broad rules that govern the admissibility of physical evidence, search results, and confessions are not fully in play, and the preliminary hearing officer, while standing in the role of the judge for the limited rules that do apply, is not the trial judge and does not issue binding rulings on suppression. The officer can consider evidence in deciding probable cause even if that same evidence might later be challenged at trial.
That is why a probable-cause determination at the Article 32 hearing can rely on evidence that the defense intends to attack. The hearing officer is answering a different question.
Where suppression actually happens
Suppression is litigated at trial through a pretrial motion to the military judge. Under the Rules for Courts-Martial, motions to suppress evidence are made before the military judge, who has the authority to receive evidence, hear argument, and issue a binding ruling on admissibility. These motions are ordinarily raised before pleas are entered, and failing to raise a known suppression issue at the proper time can forfeit it. The defense develops the factual record on the search or statement, applies the full Military Rules of Evidence, and the judge decides whether the evidence comes in or stays out.
How the Article 32 hearing still affects the later motion
Even though suppression is not decided at the preliminary hearing, the hearing is far from irrelevant to it. It functions as an early discovery and fact-development opportunity that a careful defense uses to build the suppression motion that comes later.
The hearing can lock in testimony. When agents or other witnesses describe how a search was conducted or how a statement was taken, their preliminary-hearing testimony is on the record. That testimony can be used later at trial, including as a prior inconsistent statement or, in appropriate circumstances, as prior testimony, which gives the defense a tool to expose contradictions in the suppression litigation.
The hearing can reveal the basis of the search or statement. By questioning witnesses about the circumstances of a seizure or interrogation, the defense can surface facts about consent, warrant authority, rights advisements, and timing that become the foundation of the suppression argument before the judge.
The hearing can preserve a record on production and limitations. The defense can make a clear record about what evidence and witnesses were and were not available, which can matter to later motion practice.
In short, the Article 32 hearing does not resolve suppression, but it can supply the raw material that makes a trial suppression motion succeed or fail.
Practical guidance
Do not expect the preliminary hearing officer to throw out a search or a confession. That is not the officer’s job, and asking for it misunderstands the proceeding. Instead, treat the Article 32 hearing as a chance to investigate. Question witnesses closely about how evidence was gathered, pin down the facts on the record, and identify every potential ground for suppression. Then bring the actual motion to suppress before the military judge at the proper pretrial stage, where the full rules of evidence apply and the ruling is binding.
Bottom line
The Article 32 hearing does not impact motions to suppress by deciding them, because suppression is reserved for the military judge at trial under the full Rules for Courts-Martial and Military Rules of Evidence. What the hearing does is shape the later motion by generating sworn testimony, exposing the circumstances of searches and statements, and preserving a record. Used well, the preliminary hearing becomes the foundation for a suppression fight that is won, or lost, in front of the trial judge.

Military law also changes over time.
