When a service member is facing a command-directed mental fitness board (often called a “706 board”) while also having UCMJ charges pending, a specific set of due process protections applies to prevent the two processes from improperly influencing each other. The primary protection is a limited use of the member’s statements. The service member can be ordered to participate in the mental health evaluation, but their statements made to the doctors during that evaluation generally cannot be used by the prosecution as evidence to prove guilt at the subsequent court-martial.
This protection ensures that the member can speak candidly to the mental health professionals without fear of incriminating themselves on the pending charges. The purpose of the board is to determine mental competency and responsibility, not to conduct a criminal investigation. A military defense attorney will be present during key parts of this process and will advise their client on this limited immunity. The attorney will ensure the government prosecutor does not get improper access to the full details of the mental health sessions.
However, the findings of the mental health board are provided to both the defense and the prosecution. If the board finds the accused lacks mental responsibility (i.e., they were insane at the time of the offense), this can be used as a defense at trial. If the board finds the accused is currently not competent to stand trial, the court-martial proceedings will be halted until competency is restored. These protections ensure the medical evaluation serves its proper purpose without violating the member’s right against self-incrimination.
