Spoliation refers to the loss, destruction, or failure to preserve evidence that a party had a duty to keep. In military judicial proceedings, the question is handled through a combination of the UCMJ’s equal-access rule, the discovery framework in the Rules for Courts-Martial, and constitutional due process standards drawn from Supreme Court precedent. The remedy available to an accused depends heavily on what the evidence was, why it was lost, and whether the government acted in bad faith.
The duty to preserve and the equal-access rule
Article 46 of the UCMJ guarantees the trial counsel, the defense, and the court-martial equal opportunity to obtain witnesses and other evidence. That statutory command is implemented through the discovery rules in R.C.M. 701 through 703. Among other things, the government must produce evidence that is relevant and necessary, must produce documents in the possession of military authorities that are material to the preparation of the defense, and must disclose evidence that reasonably tends to negate the guilt of the accused. There is a continuing duty to disclose, so the defense need not repeat its requests as the case develops.
Flowing from these obligations, the government has a duty to use good faith and due diligence to preserve and protect evidence and to make it available to the accused. When the government fails to do so, the proceeding has tools to respond.
The constitutional framework: Trombetta and Youngblood
For evidence that the government allowed to disappear, military courts apply the due process standards the Supreme Court set out in California v. Trombetta, 467 U.S. 479 (1984), and Arizona v. Youngblood, 488 U.S. 51 (1988). These cases draw a critical line based on the nature of the lost evidence.
If the evidence was apparently exculpatory, meaning its exculpatory value was apparent before it was lost or destroyed and the accused could not obtain comparable evidence by other reasonably available means, its loss can violate due process without any showing of bad faith. If, by contrast, the evidence was merely potentially useful, meaning no more can be said than that it might have been subjected to tests that could have helped the defense, then the accused must show that the government acted in bad faith in failing to preserve it. Under Youngblood, the presence or absence of bad faith turns on the government’s knowledge of the evidence’s exculpatory value at the time it was lost.
These standards operate alongside the disclosure rule of Brady v. Maryland, 373 U.S. 83 (1963). Under Brady, suppression of evidence favorable and material to guilt or punishment violates due process regardless of the prosecution’s good or bad faith, though impeachment evidence is material only where there is a reasonable probability that disclosure would have changed the result.
Remedies a military judge can impose
A military judge has a range of options when evidence has been lost or not preserved, and the choice is reviewed for abuse of discretion. R.C.M. 703 provides that if relevant and necessary evidence is of such central importance to an issue essential to a fair trial, and there is no adequate substitute, the military judge shall grant a continuance or other relief to attempt to produce the evidence, or shall abate the proceedings. Short of abatement, a judge may exclude related evidence, give an adverse-inference or other tailored instruction to the members, strike testimony, or fashion another remedy proportionate to the harm. Dismissal is reserved for the most serious situations where no lesser remedy can cure the prejudice.
How these disputes actually play out
In practice, the defense raises spoliation by motion, identifying the missing item, the government’s duty and failure to preserve it, the materiality of the loss, and the prejudice to the defense. The litigation usually centers on two questions: which Trombetta-Youngblood category the evidence falls into, and, where it is only potentially useful, whether the record supports a finding of bad faith. Routine loss without explanation is treated differently than deliberate destruction.
The defense’s own diligence can matter as well. The Court of Appeals for the Armed Forces has recognized that counsel’s failure to pursue lost evidence can prejudice the accused; in United States v. Suarez, 86 M.J. 65 (C.A.A.F. 2024), the court found ineffective assistance where defense counsel did not move for production of government recordings that had been lost, with no reasonable explanation for the inaction and a reasonable probability that the motion would have succeeded. The lesson is that preservation and production must be pursued affirmatively and on the record.
Takeaways
Spoliation in the military system is not governed by a single rule but by a layered structure: Article 46’s equal-access guarantee, the production and disclosure duties of R.C.M. 701 to 703, and the constitutional standards of Trombetta, Youngblood, and Brady. Whether the loss of evidence yields no remedy, an instruction, exclusion, abatement, or dismissal depends on the evidence’s exculpatory character, the availability of substitutes, and, where the evidence was only potentially useful, proof of bad faith. Because these motions are technical and fact-intensive, an accused who suspects evidence was lost or destroyed should raise the issue early and document the government’s preservation failures carefully.
