The preliminary hearing officer, often abbreviated PHO, can and must do both, but within a narrow lane. The PHO makes limited factual determinations needed to assess probable cause and necessarily evaluates the credibility and availability of witnesses, yet the role stops well short of resolving guilt or innocence. The officer answers a defined set of screening questions and recommends a disposition. The PHO does not find facts the way a panel or a military judge sitting as factfinder does at trial, and the officer cannot make the binding factual findings that decide a case. Understanding where fact assessment ends and adjudication begins is the key to the question.
What the preliminary hearing is for
Article 32 of the Uniform Code of Military Justice, as amended effective January 1, 2019, recasts the old pretrial investigation as a preliminary hearing with a limited statutory purpose. Under the statute the hearing exists to determine whether each specification alleges an offense, whether there is probable cause to believe the accused committed the offense charged, whether the convening authority has court-martial jurisdiction over the accused and the offense, and to recommend a disposition. Rule for Courts-Martial 405 implements those four objectives. This limited purpose is the frame for everything the PHO does, including any fact assessment.
The probable cause determination requires evaluating facts
Probable cause is itself a mixed question. To decide whether there is probable cause to believe the accused committed an offense, the PHO must weigh the evidence presented, consider the testimony of witnesses, and assess whether that evidence reasonably supports each element. That necessarily involves factual judgment. The hearing officer’s report is required to summarize the relevant witness testimony and documentary evidence and to state the reasoning and conclusions supporting each determination, and the officer may include observations about the testimony of witnesses and about the availability and admissibility of evidence at trial. Those observations are factual in nature. So it is inaccurate to say the PHO makes only legal rulings; the probable cause analysis is grounded in an evaluation of the facts as presented.
But these are screening assessments, not adjudicative findings
The crucial distinction is between assessing facts to gauge probable cause and finding facts that resolve a charge. Probable cause is a low threshold. It asks whether there is a reasonable belief that an offense occurred and that the accused committed it, not whether guilt is proven beyond a reasonable doubt. The PHO’s factual conclusions support a recommendation; they do not decide the case, do not bind the trial court, and carry no preclusive effect at trial. A panel or a military judge at trial is free to reach entirely different conclusions on the same evidence. In that sense the PHO’s fact work is provisional and screening oriented, not adjudicative.
What the PHO cannot do with facts or charges
The hearing officer cannot amend, add, or change the charges and specifications. The officer cannot order the case forward or dismiss it; only the convening authority decides disposition after considering the report. The PHO does not make findings of guilt and does not impose any consequence. The officer also does not have the trial judge’s full authority over evidentiary admissibility, although the PHO may comment on whether evidence would likely be admissible at trial. These limits flow from the screening function. The hearing exists to inform the convening authority’s charging decision, so the officer’s job is to analyze and recommend, not to adjudicate.
The recommendation is where law and fact meet
After assessing the evidence, the PHO answers the four statutory questions and recommends a disposition, such as referral to a particular level of court-martial, an alternate disposition, or no further action. That recommendation blends legal analysis, like whether a specification states an offense and whether jurisdiction exists, with factual assessment, like whether the evidence reasonably supports the elements. The convening authority is not bound by the recommendation and may accept, reject, or modify the proposed disposition. This non-binding quality reinforces that the PHO’s factual conclusions are advisory inputs to a decision that belongs to someone else.
Why the distinction matters to the accused
For the defense, the practical consequences follow from the screening nature of the role. Because the PHO assesses credibility and availability, defense counsel can use the hearing to test the strength of the government’s evidence and to preserve observations about weak or unavailable witnesses, which may influence the convening authority and shape later trial litigation. At the same time, because the PHO’s conclusions are not binding findings, an unfavorable probable cause determination does not establish anything at trial, and a favorable one does not guarantee dismissal. Counsel should treat the PHO’s factual assessments as persuasive, not preclusive.
Bottom line
The PHO is not limited to legal rulings. The officer makes factual assessments that are essential to the probable cause determination and routinely evaluates witness credibility, availability, and the likely admissibility of evidence. What the PHO cannot do is make the binding, adjudicative factual findings that decide guilt, change the charges, or control disposition. Those powers rest with the trial factfinder and the convening authority. The PHO’s task is to screen the case by analyzing both the law and the facts, then to recommend a path forward.
