A challenge to an Article 32 hearing officer for bias is not a formal motion decided by a judge. It is a structured objection that the defense raises directly with the preliminary hearing officer, who is judged by the same impartiality standard that governs military judges. If the officer refuses to step aside, the objection is preserved in the hearing report for the convening authority, and any error can later be litigated before the military judge once charges are referred. Understanding the sequence matters, because the Article 32 preliminary hearing is a screening proceeding, not a trial, and the tools available to the accused are correspondingly limited.
The legal standard for impartiality
Article 32 of the Uniform Code of Military Justice, as amended by the 2016 changes that took effect on January 1, 2019, requires that the preliminary hearing be conducted by an impartial hearing officer who, whenever practicable, is a judge advocate certified under Article 27(b). When a certified judge advocate cannot be appointed because of exceptional circumstances, a certified judge advocate must be available to advise the hearing officer on legal matters. Impartiality is the statutory baseline, so a credible showing of bias goes to the heart of the proceeding.
The governing manual provision, Rule for Courts-Martial 405, directs that the preliminary hearing officer’s impartiality be evaluated under the same standards that apply to a military judge under Rule for Courts-Martial 902. That rule has two prongs. The first requires recusal in any proceeding in which the officer’s impartiality might reasonably be questioned, an objective test measured by what a reasonable person knowing all the circumstances would conclude. The second lists specific disqualifying circumstances, such as personal bias toward a party, personal knowledge of disputed facts, or a prior role as counsel or witness in the same matter. Rule for Courts-Martial 405 separately disqualifies anyone who is an accuser, a witness, an investigating officer, or counsel in the case from serving as the hearing officer.
Step one: identify and document the basis
The first practical step is to articulate a concrete factual basis for the challenge rather than a general complaint about an unfavorable ruling. Adverse procedural decisions are not, by themselves, evidence of bias. Defense counsel should pin down specifics, such as a prior supervisory relationship with trial counsel, a personal connection to the accuser, prior involvement in the same investigation, or statements suggesting a prejudgment of probable cause. The challenge should map each fact onto the relevant prong of Rule for Courts-Martial 902 or the categorical disqualifications in Rule for Courts-Martial 405.
Step two: raise the objection on the record with the hearing officer
Because there is no judge presiding over an Article 32 preliminary hearing, the challenge is presented to the hearing officer directly. Counsel for the accused or for the government may question the officer’s impartiality before the hearing begins, during the hearing, or after the report is submitted to the convening authority. The hearing officer should be asked to disclose any matter that might bear on impartiality, and counsel may inquire into those matters, functioning much like voir dire of a judge. The officer then rules on the challenge. The guidance to military judges, which applies here, instructs the officer to construe grounds for disqualification broadly but not to step aside unnecessarily.
Step three: preserve the objection if recusal is denied
If the hearing officer declines to recuse, the proceeding continues, but the objection is not lost. The hearing officer is required to note objections regarding the conduct of the preliminary hearing in the report when a party requests it, so defense counsel should explicitly ask that the bias objection and its factual basis be recorded in the report that goes to the convening authority. This step is what carries the issue forward, because the convening authority reviews the report before deciding how to dispose of the charges and may consider the integrity of the proceeding in that decision.
Step four: seek relief from the convening authority and, later, the military judge
The convening authority appoints the hearing officer and may appoint a different officer if a disqualifying problem is shown, so a defense request to the convening authority for a new hearing officer is an available avenue. After referral to a court-martial, the accused may litigate the adequacy of the Article 32 preliminary hearing before the military judge, including any claim that a biased officer tainted the proceeding. The remedy at that stage is usually a new or supplemented preliminary hearing rather than dismissal, because Article 32 errors are tested for prejudice and a defective hearing is ordinarily curable. The accused generally must show that the defect had a real effect, since a referral that follows a flawed screening is not automatically void.
Why the path looks different from a trial challenge
The reason the procedure is informal is that the preliminary hearing is limited in purpose. Its function is to determine whether the specifications state offenses, whether there is probable cause, whether the convening authority has jurisdiction, and what disposition to recommend. The hearing officer does not adjudicate guilt and cannot change the charges. An impartiality problem at this stage therefore implicates the fairness of a recommendation, not a verdict, which is why the system relies on disclosure, an on-the-record objection, preservation in the report, and back-end review rather than an immediate appeal.
Practical takeaways
To challenge an Article 32 hearing officer for bias, build a specific factual record tied to Rule for Courts-Martial 902 or the categorical bars in Rule for Courts-Martial 405, raise the challenge directly with the officer and request disclosure, and if recusal is denied, insist that the objection be memorialized in the report. Follow up with the convening authority and preserve the issue for the military judge after referral. The screening nature of the proceeding means the goal is a fair hearing and an untainted recommendation, and the procedural steps are designed to protect that interest at each stage.
