Defense counsel in a court-martial frequently need help from experts, whether a forensic scientist to examine drug-testing data, a digital examiner to analyze electronic evidence, a psychologist to evaluate a client, or an investigator to develop facts. A common question is whether such requests are granted as a matter of course. The honest answer is that they are not automatic. Expert assistance is available to a military accused as a matter of due process, but only after the defense makes a specific showing of necessity. Requests are granted when that showing is made, and denied when it is not, so the outcome depends on the quality of the request rather than on any routine entitlement.
The legal foundation: Article 46 and equal opportunity
Article 46 of the UCMJ, codified at 10 U.S.C. 846, provides that trial counsel, defense counsel, and the court-martial shall have equal opportunity to obtain witnesses and other evidence, in accordance with regulations the President prescribes. This principle of equal access undergirds the defense right to expert assistance. The accompanying procedural rule, Rule for Courts-Martial (RCM) 703, addresses the production of witnesses and evidence, including the employment of expert assistants and the production of expert witnesses.
The leading authority on expert assistance is United States v. Garries, 22 M.J. 288 (C.M.A. 1986). The court, citing Article 46 and RCM 703, held that a court-martial accused is entitled to expert assistance as a matter of due process after demonstrating necessity. Importantly, this right does not depend on the accused being indigent. Service members are entitled to investigative or other expert assistance when it is necessary for an adequate defense, regardless of their ability to pay.
The necessity standard
Because the right is conditioned on necessity, the defense must satisfy a defined showing to obtain government-funded expert help. Under the Garries framework, to show necessity the defense must demonstrate three things: the reason the assistance is needed, the goal the assistance is expected to accomplish, and why the defense is unable to gather the relevant evidence or develop the relevant matter without the expert’s help.
This is a substantive burden. A bare assertion that an expert would be useful will not suffice. The request must connect the requested assistance to a specific issue in the case, explain what the expert will do, and show that the defense genuinely cannot proceed adequately without it. When a request meets this standard, …
