On August 1, 1942, military commissions concluded the trials of eight Nazi saboteurs in the United States. The U.S. Supreme Court upheld the constitutionality of these military trials in the case known as Ex Parte. This decision affirmed the government's authority to conduct military commissions during wartime for enemy saboteurs.

This historical event is noted as a significant moment in Supreme Court history, reflecting the judiciary's role in wartime legal processes.
