Can a military judge dismiss charges outright for prosecutorial misconduct that occurred during the investigation phase?

It is possible, but the rules aim first at the specific harm. Misconduct during an investigation can come from investigators or commanders as well as from government counsel, and the Military Rules of Evidence and the Rules for Courts-Martial answer it with targeted remedies: suppressing an unlawfully obtained statement or search result, sanctioning a discovery failure, or granting relief for lost evidence. Dismissal is at the far end, for misconduct whose effect on a fair trial no narrower remedy can fix. Unlawful command influence during an investigation, such as deterring a witness, has its own framework under Article 37.
Who commits “investigation-phase” misconduct
The investigation phase involves criminal investigators, commanders, and government counsel. For covered offenses committed after December 27, 2023, a special trial counsel has authority over the case (Article 24a), so the government lawyer may be involved early. The remedy depends less on the actor’s title than on what the conduct did to the evidence or to the accused’s rights.
The targeted remedies
| Problem | Remedy in the rules | Source |
|---|---|---|
| Statement obtained in violation of Article 31, the Fifth Amendment, or MRE 305 | Statement and derivative evidence inadmissible, subject to listed exceptions | Mil. R. Evid. 304(a), (b) |
| Unlawful search or seizure by U.S. personnel | Evidence inadmissible when the rule's conditions are met | Mil. R. Evid. 311(a), (b) |
| Discovery failure | Order discovery, continuance, exclusion of evidence or witnesses, or "such other order as is just under the circumstances" | R.C.M. 701(g)(3) |
| Lost or destroyed evidence of central importance | Continuance or other relief, or abatement if no adequate substitute exists | R.C.M. 703(e)(2) |
| Deterring a witness or influencing participants | Article 37 framework, with relief fitted to the harm | Article 37(a)(2)-(3), (c) |
Under R.C.M. 703(e)(2) in the Manual for Courts-Martial (2024 ed.), where evidence “is of such central importance to an issue that it is essential to a fair trial,” and there is no adequate substitute, the military judge may grant a continuance or other relief, or abate the proceedings, unless the requesting party caused the loss. Abatement stops the proceeding, which is the closest the rules in this table come to a dismissal remedy for investigation-phase failures, and it is tied to the specific loss.
Why dismissal is the last step
Each remedy above addresses a particular effect: an excluded statement cannot be used, a late disclosure can be cured with time, a missing piece of evidence can be replaced or the proceeding stopped. Dismissal goes further than any of them because it ends the case regardless of the remaining evidence. A defense motion seeking dismissal has to show what the misconduct affected and why the narrower remedies in the rules would not restore a fair trial. Where command influence is involved, Article 37(c) adds that, for violations on or after December 20, 2019, a finding or sentence can be held incorrect on that ground only if the violation “materially prejudices the substantial rights of the accused,” as covered in what unlawful command influence is and how it is proved.
Building the record
The facts that support any of these remedies come from documents and timelines: when the accused was first suspected and when warnings were given, who was present at each interview, what the search authorization covered, what evidence was collected and what became of it, and what was disclosed and when. Motions that R.C.M. 905(b) lists must be raised before pleas unless the military judge permits a later motion for good cause shown (R.C.M. 905(e)(1)), and a statement challenge is made by motion to suppress or objection. How Article 31 violations affect statements is covered in whether a statement after invoking Article 31 can be used at trial, and illegal-search evidence at an Article 32 hearing in whether illegally obtained evidence can be used at an Article 32 hearing.
