An Article 32 preliminary hearing is the step that must occur before charges can be referred to a general court-martial. Its formal purpose, set out in Article 32 of the Uniform Code of Military Justice and Rule for Courts-Martial 405, is narrow: a neutral preliminary hearing officer reviews the evidence to decide whether there is probable cause to believe an offense was committed and that the accused committed it. Yet within that probable cause framework, defense and trial counsel both pay close attention to a secondary effect of the proceeding. Because witnesses who appear testify under oath, the hearing can produce a sworn record that “locks in” what a witness says early in the case. Understanding how this works, and how the 2019 reforms limited it, helps explain why the hearing still matters strategically.
Why sworn testimony at the hearing carries weight later
The mechanism that allows a hearing to fix testimony is simple. Except for the accused, who may decline to testify or offer an unsworn statement, witnesses who appear at an Article 32 hearing testify under oath or affirmation and are subject to cross-examination. Once a witness commits to an account under oath, that account becomes a fixed reference point. If the same witness later testifies differently at trial, the earlier sworn statement can be used to challenge the new version.
The rules of evidence give that earlier statement real force. A prior statement made under oath at a proceeding is treated differently from an ordinary out-of-court remark. Under Military Rule of Evidence 801(d)(1), a witness’s prior inconsistent statement given under oath at a proceeding such as an Article 32 hearing can be offered not merely to attack credibility but as substantive evidence. In some circumstances, prior recorded testimony may also be considered under Military Rule of Evidence 804(b)(1) if the witness later becomes unavailable. Because the Article 32 record is sworn, it occupies a stronger evidentiary position than a casual interview or an unsworn pretrial statement.
How counsel uses cross-examination to fix an account
Counsel who want to pin down a witness will ask precise, closed questions that force the witness to commit to specific facts: times, sequences, distances, who said what, and what the witness did and did not observe. The goal is to capture details while memory is fresh and before the witness has been prepared further for trial. If the witness gives a different answer months later at trial, the defense can confront the witness with the sworn hearing answer and ask the panel to weigh the change. This is the practical sense in which a hearing “locks in” testimony. It does not make the witness say the same thing at trial, but it creates a sworn benchmark against which any later shift can be measured and exposed.
This dynamic cuts both ways. Trial counsel may use the same approach to secure favorable details from cooperating witnesses, and an inconsistent answer by a defense witness can be used against the defense. The locking effect belongs to whichever side preserves the more useful sworn statement.
The role of the recording and the report
A reliable record is what makes the locking effect usable. The preliminary hearing officer must submit a written report, and current practice requires that the hearing be recorded. Importantly, the report need only capture the substance of the testimony rather than a word-for-word transcript, and a court reporter is permitted but not required. Counsel who intend to rely on a witness’s exact words later should therefore ensure that an adequate recording exists, because a loose summary may not preserve the precise phrasing needed to confront a witness at trial. Preserving the recording, and obtaining access to it, is part of building the foundation for later impeachment.
Limits created by the 2019 reforms
The capacity to use the hearing this way is far more constrained than it once was. The amendments to Article 32 enacted in the 2016 defense authorization act and implemented through changes to Rule for Courts-Martial 405, effective at the start of 2019, deliberately narrowed the proceeding. Discovery is no longer an authorized purpose of the hearing, and the preliminary hearing officer is directed to focus on the probable cause determination.
Two practical consequences follow. First, live testimony is no longer guaranteed. The preliminary hearing officer may consider relevant evidence in any reasonable form, including sworn statements, investigative reports, and records, and live witnesses appear only when reasonably available and when their testimony is relevant and not cumulative. If a witness never testifies live, there is no sworn hearing account to lock in. Second, an alleged victim of a covered sex offense has an absolute right to decline to testify at the hearing under Article 32. In those cases, the defense cannot use the hearing to fix the complaining witness’s account at all.
A realistic view of the strategy
Because of these limits, treating the Article 32 hearing primarily as a tool to lock in testimony is no longer reliable. The neutral preliminary hearing officer will not allow the proceeding to become a substitute for trial discovery, and many key witnesses may never take the stand. Where live testimony does occur, however, the sworn record remains genuinely valuable. Careful cross-examination, combined with an adequate recording, can preserve a witness’s early account in a form that later carries evidentiary weight under the Military Rules of Evidence. The honest answer is that the hearing can sometimes lock in testimony, but only for witnesses who actually testify, only within the bounds the preliminary hearing officer permits, and never for a victim who exercises the statutory right to stay off the stand.
