Sexual assault prosecutions under Article 120 of the Uniform Code of Military Justice often turn on the meaning of words, gestures, and conduct, and that meaning can depend heavily on culture and language. When the accused, the complaining witness, or key witnesses come from a different cultural or linguistic background, the defense may genuinely need an expert to interpret communications, customs, or the connotations of statements made in another language. The defense can request funding for such an expert, and military law provides a defined process and standard for obtaining it.
The right to expert assistance in courts-martial
The defense in a court-martial is not limited to expert witnesses who testify at trial. It may also seek a confidential expert consultant who helps counsel understand technical, scientific, or specialized subject matter, evaluate the government’s evidence, and prepare cross-examination. The Rules for Courts-Martial recognize both expert witnesses and expert consultants and set out how the defense requests government funding for them. When the defense believes the employment of an expert is necessary, it submits a request through the convening authority, and if that request is denied, the defense may raise the matter before the military judge after referral of charges. Importantly, a request for an expert consultant may be made ex parte, which allows the defense to protect its strategy while still seeking the assistance it needs.
A cultural or linguistic expert is a recognized category
There is nothing about a cultural or linguistic expert that places it outside this framework. The categories of experts available to the defense are not limited to forensic scientists or medical examiners; they extend to any field where specialized knowledge would genuinely assist the defense. In an Article 120 case, a linguist might explain how a phrase translates, how tone or idiom carries meaning, or how a statement could be misunderstood across languages. A cultural expert might explain norms of communication, courtship, hospitality, or consent within a particular community that bear on how the charged conduct should be understood. If that knowledge is necessary to a fair defense, it fits squarely within the same rules that govern any other expert request.
The standard the defense must meet
Funding is not automatic. The defense must demonstrate that the expert is necessary, not merely helpful in some abstract sense. Military courts apply a necessity standard drawn from the case law: the accused must show more than a mere possibility of assistance and must establish a reasonable probability both that the expert would be of assistance to the defense and that denial of the expert would result in a fundamentally unfair trial. This reflects the same due process concern recognized in Ake v. Oklahoma, 470 U.S. 68 (1985), where the Supreme Court held that an indigent defendant is entitled to expert assistance when that assistance may be crucial to building a defense. In practice, the defense must articulate why the case requires this particular expertise, what the expert will examine, and how the absence of the expert would undermine a fair trial.
How to frame the request in an Article 120 case
A persuasive request connects the expertise to a concrete issue in the case rather than asserting a generalized desire for help. In a sexual assault prosecution, the defense might explain that the complaining witness and the accused communicated in a language other than English, that the meaning of specific statements is disputed, and that a qualified linguist is needed to assess translations the government intends to use. Alternatively, the defense might show that cultural norms shape how an interaction would have been understood by the participants, going to questions of consent or mistake of fact. The request should identify the proposed expert or the qualifications sought, estimate the scope and cost, and tie the assistance to the elements of the offense and the anticipated government evidence. The clearer the link between the expertise and a genuine trial issue, the stronger the showing of necessity.
What happens if the request is denied
If the convening authority denies funding, the defense can litigate the issue before the military judge. The judge evaluates whether the necessity standard is met and can order the government to provide the expert or its equivalent. A denial that is later found to be erroneous can be a significant appellate issue, because the right to necessary expert assistance is grounded in due process and the right to present a defense. For that reason, the defense should make a detailed record explaining the need, so that any denial can be reviewed meaningfully.
Practical considerations
Defense counsel should raise the need for a cultural or linguistic expert early, because identifying and retaining a qualified specialist takes time and the analysis may shape the entire defense theory. Counsel should consider whether the expert is needed first as a confidential consultant to evaluate the case, as a testifying witness, or both, since the role affects how the request is framed. Where translation accuracy is contested, the defense may need both a consultant to assess the government’s translations and a separate witness to testify. Coordinating these roles carefully strengthens both the funding request and the eventual presentation.
The bottom line
Yes, the defense can request funding for a cultural or linguistic expert during an Article 120 trial. Such an expert falls within the same rules that govern any defense expert, may be sought confidentially as a consultant, and must be justified under the necessity standard, namely a reasonable probability that the expert would assist the defense and that denial would render the trial fundamentally unfair. A well-supported request that ties the expertise to a real dispute in the case gives the defense a strong basis to obtain the assistance the law allows.
