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 …
