People often ask whether an Article 32 hearing is an adversarial proceeding, and the honest answer is that it is partly adversarial and partly not. An Article 32 preliminary hearing under the Uniform Code of Military Justice has two opposing parties, each represented by counsel, who present and contest evidence before a neutral officer. In that structural sense it carries adversarial features. Yet it is not a trial, its purpose is narrow, and the reforms implemented through Rule for Courts-Martial 405 and effective at the start of 2019 sharply limited the combative, trial-like character the proceeding once had. Understanding both the adversarial elements that remain and the limits that constrain them gives an accurate picture of what the hearing really is.
The adversarial features that remain
Several characteristics make the hearing look adversarial. There are two opposing sides, the government and the accused, and the accused is represented by counsel. Both sides may present evidence relevant to the matters the hearing decides. Witnesses who appear testify under oath or affirmation, and the defense may cross-examine witnesses the government presents in order to test their credibility. The accused enjoys important participatory rights, including the right to remain silent, the right to make an unsworn statement, and the right to be represented throughout.
These features are real. When a live witness testifies, defense counsel can probe the account, expose weaknesses, and create a sworn record. The proceeding is formal, conducted on the record, and contested by counsel on both sides. In that respect it shares the adversarial structure of a courtroom proceeding rather than the one-sided character of an internal review.
Why it is not a trial
At the same time, the hearing is fundamentally different from a court-martial. It is a preliminary hearing whose object is to determine whether probable cause exists to believe an offense was committed and that the accused committed it, along with assessing jurisdiction, the form of the charges, and a recommended disposition. It does not decide guilt or innocence. The decision-maker is a neutral preliminary hearing officer who is required to remain impartial and is directed not to become an advocate for either side. The officer does not pronounce a verdict; the officer evaluates probable cause and reports findings and recommendations that are advisory and do not bind the convening authority.
Because guilt is not at stake and the standard is only probable cause, the proceeding does not function like a full trial even where it is contested. The adversarial activity that occurs is channeled toward the limited question of probable cause rather than toward a final adjudication of the charges.
How the reforms reduced its adversarial character
The proceeding used to be far more trial-like. The earlier version of Article 32 was a more expansive, adversarial hearing in which the defense could call and extensively cross-examine witnesses, and critics described it as functioning like an inefficient mini-trial, a concern felt acutely in sexual assault cases where complaining witnesses faced extended cross-examination. The reforms responded directly to that concern.
Two changes did the most to curtail the adversarial dynamic. First, live testimony is no longer guaranteed. The preliminary hearing officer may consider relevant evidence in any reasonable form, such as sworn statements, investigative reports, and records, and live witnesses appear only when reasonably available and when their testimony is relevant and not cumulative. When the evidence comes in on paper, there is little or nothing for counsel to cross-examine. Second, an alleged victim of a covered sex offense has an absolute right to decline to testify at the hearing under Article 32. In cases where that right is exercised, the central adversarial confrontation simply does not take place. Discovery was also removed as a purpose of the hearing, further narrowing the role of contested examination.
A measured conclusion
So are Article 32 hearings adversarial in nature? They retain an adversarial framework: two represented parties, sworn testimony when witnesses appear, cross-examination, and the accused’s participatory rights, all before a neutral officer. But they are not trials, they resolve only probable cause, and the modern rules have substantially reduced the trial-like confrontation that once defined them. Live testimony is conditional, key witnesses may never appear, and a victim of a covered offense cannot be compelled to testify. The most accurate description is that an Article 32 hearing is a formal proceeding with adversarial elements operating within a deliberately limited, probable cause focused framework. An accused should expect a contest where evidence is actually disputed, but a far more constrained one than a court-martial, and should rely on counsel to make the most of the adversarial opportunities the current rules still allow.
