Before a case can be referred to a general court-martial, the military justice system requires a preliminary hearing under Article 32 of the Uniform Code of Military Justice, codified at 10 U.S.C. 832. At the center of that hearing is the preliminary hearing officer, often abbreviated PHO. Understanding what this officer does, and what the probable cause finding means, helps explain why the Article 32 hearing matters and what it is not.
A Screening Function, Not a Trial
The Article 32 preliminary hearing is a screening step. It is not a trial, and the preliminary hearing officer is not a judge who decides guilt. The reforms that took effect on January 1, 2019, arising from the National Defense Authorization Act for Fiscal Year 2016 and implemented through changes to Rule for Courts-Martial 405, refined the hearing into a focused probable cause and disposition inquiry rather than the broad discovery vehicle it had been in earlier years.
The preliminary hearing officer presides over the hearing, considers the evidence the parties present, and prepares a written report with findings and a recommendation. The officer’s conclusions are advisory. The convening authority retains the decision whether to refer charges, and is not bound to follow the preliminary hearing officer’s recommendation.
The Specific Questions the Officer Must Answer
By rule, the preliminary hearing officer addresses a defined set of questions. The officer determines whether each specification alleges an offense under the UCMJ. The officer determines whether there is probable cause to believe that the accused committed the offense or offenses charged. The officer considers whether the convening authority has court-martial jurisdiction over the accused and over the offense. Finally, the officer makes a recommendation as to the disposition that should be made of the case.
This structure keeps the hearing tied to its limited purpose. The officer is not deciding whether the accused is guilty beyond a reasonable doubt, nor weighing the case as a panel ultimately would at trial. The officer is screening the charges for legal sufficiency and a basic evidentiary foundation, and then advising the chain of command on what to do next.
What Probable Cause Means Here
Probable cause is a comparatively low threshold. In the Article 32 context, it means there are reasonable grounds to believe both that an offense occurred and that the accused committed it. The standard does not require proof to a near certainty or even a preponderance. It requires enough credible information that a reasonable person could conclude the accused likely committed the charged offense.
Because the standard is modest, a finding of probable cause does not mean the accused will be convicted. It means only that the case clears the screening bar that justifies sending it forward for a referral decision. Conversely, when the preliminary hearing officer finds that probable cause is lacking for a particular specification, that finding gives the convening authority a documented reason to reconsider whether that charge should proceed.
How the Hearing Is Conducted
At the hearing, the government typically presents evidence to support the charges. The accused has rights during the proceeding, including the right to be represented by counsel, the right to be present, the right to cross-examine witnesses who appear, and the right to present matters in defense and mitigation that are relevant to the limited purpose of the hearing. The scope of witness production and evidence is narrower than at trial, reflecting the screening nature of the proceeding.
The preliminary hearing officer evaluates testimony and documentary evidence, makes credibility observations where relevant to probable cause, and applies the legal standards to reach conclusions on each charged specification. The officer then memorializes those conclusions in the report.
Why the Officer’s Independence Matters
The integrity of the Article 32 process depends on the preliminary hearing officer exercising independent judgment. The officer is expected to evaluate the evidence neutrally and reach conclusions based on the record, not to rubber-stamp the charges. While the recommendation is advisory, a careful and candid report serves the system by identifying weak specifications, jurisdictional problems, and disposition concerns before the case consumes the resources of a full court-martial.
The Bottom Line
The preliminary hearing officer’s role is to screen, not to adjudicate. The officer determines whether the specifications state offenses, whether probable cause supports them, and whether jurisdiction exists, and then recommends a disposition. The probable cause finding is a low-threshold gatekeeping determination, and the entire report is advice that the convening authority may accept or reject. For an accused, the hearing is an early and meaningful opportunity to test the government’s case, and it should be approached with the help of qualified military defense counsel who can develop the record and argue any deficiencies in probable cause.

Military law also changes over time.
