When a serious offense is alleged in the military, a command often produces investigative paperwork long before any court-martial begins. Commanders may order administrative inquiries, and military criminal investigators prepare reports and summaries of their findings. A common question is whether those command investigation summaries can be used at the Article 32 preliminary hearing that screens a case before referral to a general court-martial. The short answer is that they generally can be considered, because the evidentiary rules at an Article 32 hearing are far more relaxed than at trial. But there are important limits and an equally important distinction between what a preliminary hearing officer may consider and what a court-martial may later admit.
What an Article 32 hearing is for
The Article 32 preliminary hearing is required before charges may be referred to a general court-martial. It is governed by Article 32 of the Uniform Code of Military Justice, codified at 10 U.S.C. § 832, and implemented by Rule for Courts-Martial 405. Since reforms narrowed its scope, the hearing serves limited purposes: to determine whether there is probable cause to believe an offense was committed and that the accused committed it, to determine whether the convening authority has jurisdiction, to consider the form of the charges, and to recommend a disposition. It is a screening function, not a full trial, and the preliminary hearing officer, the PHO, acts in a role analogous to a judge for the limited proceeding.
The Military Rules of Evidence do not fully apply
The defining feature for admissibility purposes is that the Military Rules of Evidence, with limited exceptions, do not apply at an Article 32 hearing. Because the proceeding exists only to assess probable cause and related questions, the government may meet its burden by presenting written statements, reports, and documents that would be inadmissible hearsay at a court-martial. The PHO may consider forms of evidence that could never be received at trial, so long as they are relevant to the limited purposes of the hearing.
This is why command investigation summaries are ordinarily fair game at the Article 32 stage. A summary of a command inquiry or a report of investigation that gathers witness accounts and findings is exactly the kind of documentary, hearsay-laden material the relaxed rules allow the PHO to consider. The government frequently relies on such documents to establish probable cause without producing every witness live.
The limits that still apply
Relaxed does not mean nonexistent. A few important constraints remain. First, the evidence must be relevant to the issues the hearing is authorized to decide. Second, certain protective rules carry over to the preliminary hearing even though the broader evidentiary rules do not. The rule restricting evidence of an alleged victim’s sexual behavior or predisposition continues to apply at the Article 32 stage, and the PHO follows the procedures those rules require. Privileges likewise continue to apply, so material protected by a recognized privilege does not lose its protection merely because the hearing is informal.
Third, the PHO retains the authority that a military judge would have to exclude evidence and to weigh it appropriately. The PHO is not required to credit a summary uncritically and assesses what weight the document deserves in light of its source and reliability. The defense may challenge a summary as unreliable, incomplete, or unsupported, and may argue that probable cause cannot rest on a thin or conclusory report.
Admissibility now versus admissibility later
A crucial point for the accused is that consideration at the Article 32 hearing says nothing about admissibility at the eventual court-martial. Two separate standards govern two separate proceedings. A command investigation summary that the PHO properly considers for probable cause may be plainly inadmissible at trial because it contains hearsay, lacks proper authentication, or relays the conclusions of investigators rather than competent testimony. At the court-martial, the Military Rules of Evidence apply in full, and the government will ordinarily have to produce live witnesses and lay proper foundations rather than rely on a summary.
This means the defense should not treat the Article 32 hearing as the last word on the strength of documentary proof. Material that helped the government clear the low probable-cause bar may evaporate when the rigorous trial rules apply, which can shape both negotiation and trial strategy.
How the defense uses the hearing
Even with relaxed rules, the Article 32 hearing offers the defense real value. Counsel can probe the gaps in a command summary, point out where conclusions outrun the underlying facts, and highlight the absence of live witnesses subject to cross-examination. The defense can also use the hearing to lock in the government’s theory, to obtain the PHO’s recommendation on disposition, and to preview weaknesses that will matter when the stricter trial standards apply. Where a summary rests on anonymous or unverified accounts, counsel can argue that it should be given little weight in the probable-cause determination.
Bottom line
Command investigation summaries are generally admissible for consideration at an Article 32 preliminary hearing because the Military Rules of Evidence largely do not apply there, and the PHO may rely on relevant documentary and hearsay material to assess probable cause. The main limits are relevance, the protective rules and privileges that survive into the hearing, and the PHO’s discretion over weight. Critically, consideration at the Article 32 stage does not establish that the same summary will be admissible at the court-martial, where the full rules of evidence return. An accused should have counsel test the reliability of any command summary at the hearing and prepare to challenge its admissibility at trial.
