The preliminary hearing officer is the central figure in an Article 32 proceeding. Article 32 of the Uniform Code of Military Justice requires a preliminary hearing before charges can be referred to a general court-martial, and Rule for Courts-Martial 405 places that hearing in the hands of a single officer detailed for the purpose. This person is not a judge, a prosecutor, or defense counsel. The preliminary hearing officer reviews the charges and the evidence and reports findings and recommendations to the authority who will decide what to do with the case. Knowing who fills this role, what qualifications the position calls for, and how the officer is expected to behave clarifies what an accused can expect from the hearing.
Who is appointed
The convening authority details the preliminary hearing officer. Under current practice, the preliminary hearing officer should be a judge advocate, meaning a military attorney, whenever that is practicable. The preference for a lawyer reflects the nature of the task: the officer must apply legal standards, rule on the relevance and availability of evidence, and assess probable cause. When detailing a judge advocate is not practical, the convening authority may instead detail an impartial commissioned officer to conduct the hearing. In that situation the officer is expected to seek legal advice as needed, but the appointment of a non-lawyer remains the exception rather than the norm.
The position is filled case by case. There is no standing office of preliminary hearing officers; rather, an officer is selected and detailed for the particular matter. That officer should have no prior involvement that would compromise neutrality in the case at hand.
The duty of impartiality
The defining characteristic of the role is neutrality. The preliminary hearing officer is intended to be a neutral and detached figure who represents neither the government nor the defense. Rule for Courts-Martial 405 makes this explicit by directing that the preliminary hearing officer shall not depart from an impartial role and become an advocate for either side. The officer does not build the prosecution’s case and does not assist the defense in shaping a strategy. The officer’s function is to evaluate, not to advocate.
This impartiality requirement shapes everything the officer does at the hearing. The officer may question witnesses to clarify the evidence, but the questioning must serve the neutral task of understanding the facts, not the partisan goal of strengthening one side. If an officer crosses into advocacy, that conduct can become grounds for challenge.
What the officer is responsible for deciding
The preliminary hearing officer’s task is defined by the limited purposes of the hearing. The officer determines whether there is probable cause to believe that an offense was committed and that the accused committed it, considers whether the convening authority has court-martial jurisdiction over the accused and the offense, considers the form of the charges, and recommends a disposition of the case. The officer reaches these conclusions by reviewing the evidence the parties present, which may take the form of sworn statements, reports, records, and, where appropriate, live testimony.
To carry out these duties the officer rules on certain evidentiary questions, such as whether a requested witness is reasonably available and whether proposed evidence is relevant and not cumulative. These rulings are made within the hearing’s narrow scope. The officer is not conducting a trial, not deciding guilt, and not resolving every dispute in the case.
The report the officer produces
When the hearing concludes, the preliminary hearing officer prepares a written report accompanied by a recording of the proceeding. The report sets out the officer’s probable cause determination, addresses jurisdiction and the form of the charges, and includes a recommended disposition. It captures the substance of the testimony and evidence rather than serving as a verbatim transcript. This report goes to the convening authority, who uses it, along with required legal advice, in deciding how to proceed.
It is important to understand the report’s status. The preliminary hearing officer’s findings and recommendations are advisory. They inform the convening authority but do not bind that authority, who retains the discretion to make the final disposition decision. The officer recommends; the convening authority decides.
Why the choice of officer matters to the accused
Because the preliminary hearing officer evaluates probable cause and recommends a disposition, the officer’s qualifications and neutrality directly affect the fairness of the hearing. An accused benefits from an officer who understands the governing rules, applies the correct legal standards, and remains genuinely detached from both sides. The preference for a judge advocate, combined with the explicit command that the officer not become an advocate, is designed to secure exactly that. If an accused believes the detailed officer is biased or has a disqualifying prior involvement, the appropriate course is to raise the concern so it can be addressed, because the integrity of the entire preliminary hearing depends on the impartiality of the person conducting it.

Military law also changes over time. The Military Justice Act of 2016 (effective January 1, 2019) and subsequent National Defense Authorization Acts renumbered and rewrote many punitive articles, revised the Article 32 preliminary hearing, and altered sentencing, clemency, and appellate procedures.
