Compelling overseas witnesses to testify in courts-martial presents unique challenges requiring various legal mechanisms. For military witnesses stationed overseas, commanders can order their appearance under Article 46 of the UCMJ. Military personnel remain subject to orders regardless of location, making their compulsion relatively straightforward through coordination between commands and funding for travel when necessary.
Civilian witnesses overseas pose greater difficulties. The military lacks subpoena power beyond U.S. territorial jurisdiction. For U.S. citizens abroad, the government may request voluntary cooperation or utilize depositions under Rule for Courts-Martial 702. Some Status of Forces Agreements (SOFAs) provide mechanisms for compelling testimony from civilians in host nations. Additionally, the trial counsel can seek assistance through diplomatic channels or international legal assistance treaties.
When physical appearance isn’t feasible, remote testimony via video teleconference (VTC) under RCM 914A offers an alternative. The military judge must find that the witness’s physical presence is not reasonably available and that VTC testimony is necessary to ensure a fair trial. Defense counsel can object if remote testimony would materially prejudice the accused’s rights. The prosecution typically bears the burden of demonstrating good faith efforts to secure witness attendance before courts allow alternative testimony methods.
