Investigative audio recordings, such as a recorded interrogation, a pretext phone call, or a witness interview, can be central to a court-martial. When the original recording is lost, overwritten, or never properly preserved, the accused may have suffered real harm to the ability to test the government’s case. On appeal, the questions are whether that loss violated the accused’s rights and, if so, what the Courts of Criminal Appeals or the Court of Appeals for the Armed Forces (CAAF) can do about it. The available remedies range from a new trial to dismissal, but they depend heavily on the government’s culpability and the importance of what was lost.
The constitutional framework: bad faith and materiality
The starting point is the due process doctrine governing lost evidence. The Supreme Court drew a sharp line in two cases. Under California v. Trombetta, when the government fails to preserve evidence that has an apparent exculpatory value and is not reasonably replaceable by other means, due process may be violated regardless of good faith. Under Arizona v. Youngblood, when the lost evidence is merely “potentially useful,” meaning its exculpatory value is unknown, there is no due process violation unless the accused shows bad faith on the part of the government.
For most lost investigative recordings, the recording is potentially useful rather than demonstrably exculpatory, because no one knows exactly what cross-examination it would have supported. That places the case under Youngblood and makes bad faith the pivotal question. Negligent loss, an automatic overwrite, or a failure to follow retention policy generally does not meet the bad faith threshold, while deliberate destruction to deprive the defense of the material does.
The appellate court therefore asks a sequence of questions. Was the recording materially exculpatory and irreplaceable, triggering Trombetta? If not, was it potentially useful and lost in bad faith, triggering Youngblood? And independent of the constitutional test, did the loss prevent a fair trial under the military’s own fairness standards?
Remedies at the appellate level
When an appellate court concludes that the loss prejudiced the accused or violated due process, several remedies are available, calibrated to the severity of the violation.
The most common remedy is to set aside the findings and authorize a rehearing. This gives the government the option to retry the accused, but on a record cleansed of the tainted evidence and often with an instruction or evidentiary ruling addressing the missing recording. A rehearing is appropriate when the error affected the findings but a fair retrial remains possible without the lost material.
A stronger remedy is to set aside the findings and dismiss the affected charges, with or without prejudice. Dismissal is warranted when the lost recording was so central that no fair trial is possible without it, or when the government’s conduct was egregious. Where the constitutional violation goes to the heart of the case and cannot be cured, dismissal with prejudice may be the only adequate remedy.
An intermediate remedy addresses the use of derivative or related evidence. The appellate court may hold that the trial judge should have suppressed testimony or other evidence that depended on the lost recording, or should have given a remedial instruction permitting the panel to draw an inference adverse to the government from the loss. If the failure to suppress or instruct affected the outcome, the court can set aside the findings on that basis.
Finally, appellate courts can grant relief on the sentence rather than the findings, reducing or disapproving portions of the sentence when the error’s prejudice is better measured there than in the verdict.
Article 59(a) and the prejudice requirement
A critical filter applies to nearly all of these remedies. Article 59(a), UCMJ, provides that a finding or sentence may not be set aside on the basis of an error of law unless the error materially prejudiced the substantial rights of the accused. So even when an appellate court agrees the government should have preserved the recording, the accused must show that the loss had a meaningful effect on the trial. The court will assess how important the recording was, whether its contents were available through other means such as a transcript or a witness’s testimony, and whether the defense was able to mount an effective challenge despite the loss. A harmless loss, even if regrettable, will not move the court.
Preservation and the record on appeal
There is also a distinct problem that arises when the missing audio is a recording of the court-martial proceedings themselves, as opposed to investigative material. When part of the proceedings was not recorded or the recording was lost, the question becomes whether the record of trial is sufficiently complete and, where required, verbatim. A verbatim transcript is required when the sentence includes confinement beyond a defined threshold, forfeitures above a set level, or a punitive discharge. If a substantial omission in the record cannot be cured, the appellate court may be required to limit the affirmable sentence to what a non-verbatim record can support, or to authorize a rehearing. This is a separate track from the investigative-evidence analysis, but it shows how the loss of audio can drive appellate relief through the completeness-of-the-record doctrine as well.
Practical guidance for the appellate record
To preserve these issues, the defense should litigate the loss at trial through a motion to dismiss or for appropriate relief, request adverse-inference instructions, and build a factual record on how the recording was lost, what it likely contained, and why no substitute exists. The strength of the appellate remedy tracks that record. A clear showing of bad faith points toward dismissal, while negligent loss of important but replaceable material points toward a rehearing, a remedial instruction, or sentence relief, and a showing that the loss made no difference will leave the conviction intact under Article 59(a).
