The Article 32 Preliminary Hearing

The Article 32 preliminary hearing is the procedural gate every general court-martial must pass through under 10 U.S.C. § 832. Following amendments in the FY 2014 and FY 2015 National Defense Authorization Acts, Article 32 transformed from an “investigation” into a narrowly scoped “preliminary hearing” focused on probable cause and disposition recommendations.

Background: From “Investigation” to “Preliminary Hearing”

For most of its history, Article 32 was styled as an “investigation,” modeled loosely on a civilian grand jury. The investigating officer (IO) was empowered to take sworn testimony, subpoena witnesses, and compile a substantive evidentiary record. Defense counsel routinely used Article 32 hearings as a discovery device — cross-examining the alleged victim, locking witnesses into a sworn record, and probing the government’s theory of the case before trial.

That practice came under sustained criticism. In high-profile sexual assault cases, defense cross-examinations at Article 32 were perceived as invasive and sometimes humiliating, with little corresponding benefit because the IO’s sole job was to determine whether the case should proceed at all. Congress responded in two waves: the FY 2014 National Defense Authorization Act, signed in December 2013, and the FY 2015 NDAA, signed in December 2014. Together they rewrote Article 32 from the ground up, renaming the proceeding a “preliminary hearing” and stripping the hearing officer’s investigative role.

The reformed statute reflects a deliberate choice. Article 32 is no longer a discovery vehicle. It is a probable-cause screen — closer in function to a federal preliminary hearing under Federal Rule of Criminal Procedure 5.1 than to a grand jury inquest.

What the Preliminary Hearing Officer Decides

Under the current statute, the preliminary hearing officer (PHO) is asked to make four discrete determinations:

1. Whether the specification alleges an offense under the UCMJ. This is a pleadings inquiry. The PHO compares the language of the charge sheet against the elements of the offense charged.
2. Whether there is probable cause to believe the accused committed the offense. The standard is the same probable cause familiar from Fourth Amendment search-and-seizure law — a reasonable belief based on the totality of the circumstances. It is not proof beyond a reasonable doubt or even a preponderance of the evidence.
3. Whether the convening authority has court-martial jurisdiction over the accused and the offense. Personal jurisdiction (active duty, retiree status, certain reservists in qualifying status) and subject-matter jurisdiction over the alleged conduct.
4. A recommendation on the disposition of the case. Should the charges be referred to a general court-martial, sent to a special court-martial, handled administratively, or dismissed?

The PHO must be a judge advocate in the grade of O-4 or higher whenever practicable. The statute requires that hearings of “exceptional gravity” — capital cases or those involving senior officers — be conducted by a more senior PHO when feasible. The PHO’s report is advisory; the convening authority remains the decision-maker on referral.

Paper-Based Practice and Witness Testimony Limits

The most operationally significant change from the pre-2014 regime is the curtailment of live testimony. Under the current Rule for Courts-Martial 405, the PHO is required to consider relevant evidence the parties present in any reasonable form: sworn statements, investigative reports, lab results, business records, and so on. Live witnesses are permitted, but only when the witness is “reasonably available” and the proposed testimony is “relevant and not cumulative.”

Two limits matter most in practice:

• The alleged victim of a sex offense may not be required to testify. Article 32(d)(3) gives the alleged victim of a Chapter 47 sex offense an absolute right to decline to appear. The PHO may consider the victim’s prior statements as evidence in lieu of live testimony. Defense counsel still sometimes request the victim’s appearance, but the request is functionally a request to the victim, not a subpoena to the victim — and the victim need not respond.
• Witnesses outside the subpoena range or under a privilege need not appear. “Reasonable availability” turns on travel costs, operational tempo, and the marginal value of live testimony given the narrow purpose of the hearing.

Because most Article 32 hearings now run on paper, they tend to be short. A hearing that once consumed two or three days of in-person testimony is now frequently completed in an afternoon, with the PHO issuing a written report several weeks later.

Waiver as Part of a Pretrial Agreement

The accused may waive the Article 32 hearing in writing. Waiver is most common when the accused has negotiated, or expects to negotiate, a pretrial agreement (PTA). Two scenarios recur:

• Waiver in exchange for case-cap protection. The accused waives Article 32 in exchange for the convening authority’s commitment to refer the case to a special court-martial (with its lower jurisdictional sentence cap) instead of a general court-martial.
• Waiver because the hearing offers little defense value. Where the government’s evidence is strong, the offenses are well-pleaded, and the accused intends to plead guilty, the Article 32 hearing offers no realistic chance of dismissal and consumes attorney-client time better spent preparing for trial or negotiating sentence.

Defense counsel should weigh the waiver decision against the residual benefits of the hearing — even a paper-based proceeding produces a written record of the government’s theory, surfaces obvious pleading defects, and forces the government to commit, in writing, to a probable-cause showing.

The Office of Special Trial Counsel and Article 24a

The FY 2022 National Defense Authorization Act created an entirely new disposition track for the most serious enumerated offenses. Codified at 10 U.S.C. § 824a, Article 24a transferred prosecutorial discretion for a list of “covered offenses” — sexual assault, sexual misconduct, murder, manslaughter, kidnapping, child pornography, and certain domestic violence offenses among them — from the accused’s commander to a specialized prosecutor: the Office of Special Trial Counsel (OSTC). The first OSTC offices became fully operational in December 2023.

Three consequences flow directly to the Article 32 process:

1. OSTC is the disposition decision-maker. When charges fall within Article 24a’s covered-offense list, the convening authority no longer chooses whether to refer; OSTC does. The Article 32 PHO’s recommendation flows to OSTC, not to the unit commander.
2. OSTC may convene Article 32 hearings on its own initiative. OSTC can prefer charges and convene the preliminary hearing without waiting for the unit chain of command to act.
3. Multi-tier review. A covered-offense Article 32 report is reviewed by OSTC counsel before disposition. The PHO’s findings on probable cause carry weight, but OSTC retains the discretion to dismiss, defer, or send to a different forum.

Defense counsel handling a covered-offense case must therefore engage OSTC directly during the Article 32 phase. The traditional practice of negotiating with the staff judge advocate for the convening authority is no longer the exclusive path.

Strategic Considerations for Defense Counsel

For the defense, the Article 32 preliminary hearing is most useful when used surgically rather than as a discovery dragnet:

• Probe pleading defects early. A vague specification, a defective charging theory, or a missing element is easier to fix at Article 32 than at trial. PHOs routinely flag these issues, and convening authorities (or OSTC) often re-prefer charges in response.
• Frame the disposition narrative. The PHO’s recommendation matters even when it is advisory. A well-supported defense submission — alternative theories, mitigation evidence, jurisdictional concerns — can move the needle from referral to a special court-martial or to administrative resolution.
• Avoid surprising the alleged victim. Even when defense counsel could request the victim’s appearance, doing so without strategic justification rarely advances the defense and often hardens the government’s posture.
• Document the record for appeal. Errors in the Article 32 process, including unduly restricted access to evidence, can be preserved for later appellate review.

For the government, the Article 32 phase is increasingly a screening exercise rather than a rehearsal. Trial counsel and OSTC attorneys should treat the PHO’s report as a litigation risk assessment — if probable cause is thin or jurisdiction is contested, those weaknesses will follow the case to a court-martial.

Recent Appellate Guidance

The Court of Appeals for the Armed Forces (CAAF) and the service Courts of Criminal Appeals have issued a steady stream of Article 32 decisions since the 2014 reforms. The pattern is clear: appellate courts will not reverse a conviction for an Article 32 procedural defect absent a showing of material prejudice to the substantial rights of the accused. Errors that would have been fatal in the pre-2014 regime — restricted cross-examination, denial of a particular witness, refusal of certain documents — are now generally treated as harmless when the underlying purpose of the hearing (probable cause screening) was nonetheless achieved.

This high prejudice threshold cuts both ways. It limits defense relief on appeal, but it also discourages the government from over-litigating Article 32 procedural disputes. The current incentive structure pushes both sides toward an efficient, paper-based proceeding.

Frequently Asked Questions

Is the Article 32 preliminary hearing required for every court-martial?

No. Only general courts-martial require an Article 32 preliminary hearing or a valid waiver. Special and summary courts-martial do not.

Can the accused be present at the hearing?

Yes. The accused has an absolute right to be present, to be represented by counsel (military defense counsel and, if obtained, civilian counsel), and to make a statement.

What happens if the PHO recommends against referral?

The convening authority — or OSTC for covered offenses — is not bound by the PHO’s recommendation. The case may still be referred to a general court-martial. In practice, however, a “no probable cause” finding by the PHO is rare and typically results in either dismissal, downgrade to a special court-martial, or re-preferral with new charges.

How long does the Article 32 hearing take?

Most contemporary Article 32 hearings are completed in a single day, often in a single afternoon. The PHO’s written report typically follows within several weeks.

Does Article 32 apply to retirees recalled to active duty?

Yes, when court-martial jurisdiction otherwise attaches. The PHO will address jurisdiction explicitly in the report.
