SECTION 10: ABOUT COURT-MARTIAL PROCEEDINGS

A court-martial is a military court convened to try members of the armed forces for offenses under military law. The Billy Mitchell case was prosecuted under the 96th Article of War, a general provision covering conduct prejudicial to good order and discipline. The proceedings lasted seven weeks with a thirteen-member panel of general officers serving as both judge and jury. After hearing 1.4 million words of testimony from 99 witnesses, the panel returned a guilty verdict on all specifications. This case established a precedent that truth is not a defense against charges of insubordination in military justice. The 1958 review by the Air Force Board for Correction of Military Records concluded Mitchell “was tried for his views rather than a violation of Article 96,” but the Secretary of the Air Force declined to overturn the conviction. The case remains studied at military academies and law schools as a landmark proceeding examining military discipline versus freedom of expression.
