Article 120 of the Uniform Code of Military Justice, codified at 10 U.S.C. 920, governs rape, sexual assault, aggravated sexual contact, and abusive sexual contact. These cases frequently turn on the believability of a single complaining witness, so any documentation that bears on perception, memory, or reporting can become significant. Mental health records are among the most contested categories of such documentation. Whether they affect credibility depends less on the existence of a diagnosis and more on whether the defense can lawfully obtain the records and tie specific information to a recognized basis for impeachment.
Mental Health History Is Not Automatically Relevant
A common misconception is that a complainant’s mental health treatment, by itself, undermines an allegation. Military law does not treat a diagnosis as a credibility flaw. A history of depression, anxiety, post-traumatic stress, or counseling does not make a witness less worthy of belief. Members are not permitted to assume that a person who has sought mental health care is dishonest or imagines events. For mental health documentation to matter, it must connect to something the factfinder may properly consider, such as an ability to perceive or recall the event, a documented condition that affects accuracy, or prior statements that conflict with trial testimony.
The MRE 513 Privilege Controls Access
Military Rule of Evidence 513 establishes a psychotherapist-patient privilege. A patient may refuse to disclose, and prevent others from disclosing, confidential communications made to a psychotherapist for the purpose of diagnosis or treatment of a mental or emotional condition. This privilege protects the conversation itself, which means the defense cannot simply demand a complainant’s therapy file in the hope of finding useful material.
The Court of Appeals for the Armed Forces clarified the boundary of this privilege in United States v. Mellette, 82 M.J. 374 (C.A.A.F. 2022). The court held that the phrase covering a communication between a patient and a psychotherapist does not naturally extend to all evidence of diagnosis and treatment. Routine records that do not memorialize actual communications, including some that note a diagnosis or the treatment provided, are not uniformly privileged. Records remain protected to the extent they reflect the substance of confidential communications. The practical effect is that diagnoses, dates of care, and treatment provided may be discoverable in a way that the contents of a counseling session are not.
How a Military Judge Decides Disclosure
Because the privilege is real but not absolute, access usually runs through a litigated motion. The defense must articulate a specific factual basis showing that the records likely contain evidence relevant to a contested issue, rather than offering a general request to search for impeachment. If that threshold is met, the military judge typically reviews the records privately, outside the presence of the parties, to determine what, if anything, must be released. This in camera procedure balances the witness’s confidentiality against the accused’s right to a fair trial. The judge releases only the portions that meet the legal standard and remain unprotected after Mellette.
When Documentation Genuinely Bears on Credibility
Mental health documentation affects credibility in limited and concrete ways. A record may show that the witness gave an account of the incident to a provider that differs from later testimony, which is classic impeachment by prior inconsistent statement. A documented condition might bear on the capacity to perceive or remember if competent evidence connects the condition to accuracy in this case, rather than inviting speculation. Records may also reveal a motive to fabricate or a bias if the documentation reflects it directly. In each situation, the defense must still satisfy the ordinary rules governing relevance and impeachment, and the military judge may limit how the evidence is used.
Limits the Defense Must Respect
Several guardrails restrain the use of mental health information. The judge may exclude material whose tendency to confuse the issues or unfairly prejudice the panel outweighs its value. Evidence of a complainant’s other sexual behavior or predisposition is separately restricted by the rape shield provisions of Military Rule of Evidence 412 and is not made admissible merely because it appears in a mental health file. Counsel may not use a diagnosis to suggest, without foundation, that a particular condition makes a person prone to lying. Crossing these lines can draw a sustained objection and a curative instruction.
Practical Takeaways
The presence of mental health documentation does not strengthen or weaken an Article 120 allegation on its own. Its effect depends on lawful access under Military Rule of Evidence 513 as interpreted in Mellette, a judicial determination that specific contents are relevant and unprivileged, and a proper evidentiary theory connecting the information to perception, memory, prior statements, or motive. A service member who believes mental health records bear on a case should preserve the issue early and let counsel pursue disclosure through the established motion practice, because informal attempts to obtain protected records can fail and can damage the defense before trial begins.
