The Article 32 preliminary hearing is the gateway between an investigation and a general court-martial. Before a service member can be tried by general court-martial, Article 32 of the Uniform Code of Military Justice, codified at 10 U.S.C. 832, generally requires that a preliminary hearing be held. The way evidence is treated at that hearing differs sharply from the rules that govern a trial, and those differences shape what defense counsel can accomplish, what the government must disclose, and how the hearing officer reaches a recommendation. Evidentiary issues are at the center of nearly every disputed Article 32 hearing.
From Investigation to Preliminary Hearing
For decades the Article 32 proceeding functioned as a broad pretrial investigation that doubled as a powerful discovery tool for the defense. That changed with the National Defense Authorization Acts for fiscal years 2014 and 2015, which rewrote the statute and narrowed the proceeding into a focused preliminary hearing. The reforms were driven in large part by concern that sexual assault complainants were being subjected to wide-ranging and intrusive questioning at hearings that had drifted far beyond their proper purpose.
After the reforms, the hearing has a defined and limited set of objectives. The preliminary hearing officer determines whether there is probable cause to believe that an offense was committed and that the accused committed it, determines whether a court-martial would have jurisdiction over the offense and the accused, considers the form of the charges, and recommends a disposition of the case. The hearing is no longer designed to serve as a vehicle for open-ended discovery. This change in purpose is the source of most of the evidentiary tension that arises today.
The Limited Role of the Military Rules of Evidence
At a court-martial, the Military Rules of Evidence apply in full. At an Article 32 preliminary hearing, they do not. Rule for Courts-Martial 405 makes only a narrow set of evidentiary rules applicable to the hearing. The rules on privileges apply. The protections of Military Rule of Evidence 412, the rape shield rule, apply. And the rules concerning the privilege against self-incrimination apply. The remaining rules of evidence, including the hearsay rules and most foundational requirements, do not bind the preliminary hearing officer.
The practical result is that the preliminary hearing officer may consider relevant information in any reasonable form. Sworn statements, investigative reports, laboratory results, business records, and similar materials may be received and weighed even though they would require live testimony and formal foundation at trial. This relaxed approach reflects the screening function of the hearing. The officer is testing for probable cause, not rendering a verdict, so the strict gatekeeping that protects a panel of members at trial is not imposed at this preliminary stage.
The Hearing Officer’s Authority Over Evidence
Within this framework, the preliminary hearing officer steps into a role that resembles, but does not fully match, that of a military judge. When the limited applicable evidentiary rules call for a ruling, the term military judge in those rules is read to mean the preliminary hearing officer. The officer may exclude evidence under the rules that do apply and may rule on whether a claimed privilege protects particular material.
There is a clear limit. The preliminary hearing officer does not possess the military judge’s authority to order the production of privileged matters. The officer can decide whether a privilege applies when a party seeks to offer evidence that another party claims is protected, but the officer cannot compel the disclosure of privileged information. Disputes that require compelled production of protected material are reserved for the military judge once the case reaches trial.
Witnesses, Victim Protections, and the Scope of Examination
One of the most significant evidentiary changes flowing from the reforms concerns witnesses, and particularly alleged victims. An alleged victim has the right to decline to testify at the preliminary hearing. When a victim declines, the hearing officer must consider whether and how the matter can be presented through other reasonable forms of evidence, such as prior statements. This protection was a central goal of the statutory overhaul and directly limits the defense’s ability to cross-examine the complainant at this early stage.
The scope of permissible examination is likewise constrained by the hearing’s narrow purpose. Because the proceeding exists to test probable cause, jurisdiction, the form of the charges, and disposition, examination that strays into general discovery or that probes matters unrelated to those objectives can be curtailed. Counsel who treat the hearing as a deposition will find that the presiding officer has both the authority and the mandate to keep the examination tethered to the limited issues before the hearing.
Privileges and Protected Information
Because privileges are among the few evidentiary rules that apply, privilege disputes loom large at Article 32 hearings. Claims may involve the attorney-client privilege, the psychotherapist-patient privilege, the clergy privilege, the marital privileges, and others recognized in the Military Rules of Evidence. The hearing officer may decide whether a privilege applies to material that a party seeks to introduce, but cannot order privileged material produced over an objection. When access to arguably privileged information is genuinely needed, the appropriate path is to litigate the question before the military judge at trial.
The rape shield protections of Rule 412 also apply at the hearing. Evidence of an alleged victim’s prior sexual behavior or predisposition is subject to the same threshold limits that govern at trial, which prevents the preliminary hearing from becoming a forum for the kind of intrusive inquiry the reforms were meant to eliminate.
Why These Issues Matter
The evidentiary rules at an Article 32 hearing are not a technicality. They determine how much the defense can learn before trial, whether a complainant must appear, what documents and reports the hearing officer may rely on, and how privilege fights are resolved. Because the hearing officer can consider evidence in relaxed forms, the government can establish probable cause without producing live witnesses for every point, and the defense must adjust its strategy accordingly. At the same time, the privilege rules, the self-incrimination protections, and the rape shield rule still impose real limits that careful counsel can invoke.
A preliminary hearing officer’s report, including the probable cause determination, is a recommendation. The convening authority retains the discretion to refer charges to a general court-martial even where the officer recommends against it, which means the hearing’s evidentiary rulings, while important, do not bind the ultimate referral decision. For the accused, the hearing remains the first meaningful opportunity to test the government’s case, to preserve issues, and to begin shaping the defense, which is why mastery of these evidentiary rules is essential for anyone facing referral to a general court-martial.
