Yes, a military defense team has the right to request government funding for expert consultants and witnesses who are necessary to prepare an adequate defense, and this absolutely includes a cultural or linguistic expert in an Article 120 (sexual assault) trial. This right is a key component of the Sixth Amendment right to a fair trial and is codified in military regulations.
In many sexual assault cases, particularly those that occur overseas or involve individuals from different cultural backgrounds, cultural and linguistic nuances can be critical. A cultural expert can help the defense team and the court-martial panel understand cultural norms regarding relationships, communication, and consent that may be unfamiliar to them. A linguistic expert can analyze communications between the accused and the accuser, providing an expert opinion on the true meaning of translated words or culturally specific phrases that could easily be misinterpreted.
The defense attorney will file a formal request for expert funding with the convening authority or the court. The request must detail why the expert is necessary for the defense and how their testimony would be relevant and material to the case. If the request is approved, the government will provide the funding for the defense to hire the expert. This ensures that an accused service member has the resources they need to present a complete and culturally informed defense.
