When the government withholds part of an investigative file behind a claim of privilege, the defense may later learn that the privilege was waived, narrowed, or never properly invoked in the first place. The question on appeal is whether the failure to turn over that material requires setting aside the conviction. The answer depends on what was withheld, why disclosure was required, and whether the accused was prejudiced by its absence.
The Disclosure Framework in Courts-Martial
Discovery in the military justice system is broader than in many civilian systems. Rule for Courts-Martial 701 governs the government’s disclosure obligations, and it is supplemented by the constitutional rule from Brady v. Maryland, which requires the prosecution to disclose evidence favorable to the accused that is material to guilt or punishment. Under RCM 701(a)(6), trial counsel must disclose evidence that reasonably tends to negate the guilt of the accused, reduce the degree of guilt, or reduce the punishment.
This duty is not limited to material physically sitting in the prosecutor’s office. Trial counsel is responsible for searching her own files, the files of law enforcement agencies that participated in the investigation, and the files of closely related cases maintained by entities aligned with the prosecution. A prosecutor can violate the disclosure duty without ever knowing the evidence exists, simply by failing to look far enough or in the right place. That principle is what makes a privilege waiver buried in an investigative file legally significant: if favorable material becomes discoverable because a privilege no longer shields it, the government’s obligation to find and produce it attaches.
How Privilege Interacts with Disclosure
Investigative files often contain material that the government claims is protected, whether by a law enforcement investigative privilege, deliberative process protections, or similar interests. A privilege can be waived expressly, by voluntary disclosure to a third party, or by the government’s own use of the underlying material. When a waiver occurs, the protected status of the document falls away, and any favorable, material content within it becomes subject to the ordinary disclosure rules.
The proper procedure when the government wants to withhold part of a file is for trial counsel, or an attorney familiar with the Brady and Giglio doctrines acting under trial counsel’s supervision, to review the withheld portions to confirm that nothing favorable to the defense is being kept back. Where there is a genuine dispute about privilege, the military judge can conduct an in camera review to resolve the claim. A failure to disclose a waiver that should have been recognized can therefore be a failure of the disclosure system itself, not merely a privilege dispute.
The Standard for Reversal
A disclosure failure does not automatically result in reversal. Military appellate courts ask a sequence of questions. First, was the undisclosed material favorable to the accused, either because it was exculpatory or because it could have impeached a government witness. Second, did the government fail to disclose it when disclosure was required. Third, did the accused suffer prejudice as a result.
The prejudice inquiry is the decisive step, and it follows the materiality standard developed in Brady and its successors. A failure to disclose is material if there is a reasonable probability that the result of the proceeding would have been different had the evidence been produced. The Supreme Court has explained that this does not require the accused to show he more likely than not would have been acquitted. The question is whether, in the absence of the evidence, he received a fair trial, meaning a trial resulting in a verdict worthy of confidence. If the suppressed material undermines confidence in the outcome, the conviction cannot stand.
When a Waiver Failure Tips Toward Reversal
The likelihood of reversal rises when the withheld material goes to the heart of the case. If a privilege waiver would have exposed a prior inconsistent statement by a key witness, evidence of a cooperation deal, or facts contradicting the government’s theory, the probability that the result was affected increases. Conversely, when the withheld material is cumulative of other evidence the defense already had, or relates to a peripheral issue, courts are far less likely to find the required prejudice, even if the government’s handling of the privilege was flawed.
The strength of the remaining evidence also matters. A conviction supported by overwhelming and independent proof is harder to disturb than one resting on the testimony of a single witness whose credibility the withheld material could have damaged.
Preservation and the Standard of Review
How the issue was handled at trial affects the appellate analysis. When the defense specifically requested the material or objected to its withholding, and the request was denied, the appellate court reviews the disclosure ruling against the backdrop of that demand. When the defense had no way to know the material existed because the privilege concealed it, the failure is evaluated under the constitutional materiality standard regardless of whether a precise request was made, because the obligation to disclose favorable, material evidence does not depend on a defense request. The remedy also varies with the timing of the discovery. If the waiver and the withheld material come to light during trial, the judge can order disclosure, grant a continuance, or fashion another remedy that cures the problem before the verdict. If the failure surfaces only on appeal, the court is left to assess prejudice on a cold record, asking whether confidence in the verdict is undermined. The later the disclosure failure is discovered, the more the analysis turns entirely on the materiality of what was kept back.
The Practical Lesson
A privilege claim is not a permanent shield, and a waiver changes the government’s obligations. When the government fails to disclose material that a recognized waiver made discoverable, and that material is favorable and material under the Brady standard, reversal is a real possibility. But the outcome is never automatic. The accused must connect the missing material to a reasonable probability of a different result. That connection, rather than the bare fact of nondisclosure, is what determines whether an appellate court will set the conviction aside.
