Until 1920, court-martial convictions were reviewed either by a commander in the field or by the President, depending on the severity of the sentence or the rank of the accused. The absence of formal review received critical attention during World War I, and the Army created an internal legal review process for a limited number of cases. Following the war, in the Act of June 4, 1920, Congress required the Army to establish boards of review, consisting of three lawyers, to consider cases involving death, dismissal of an officer, an unsuspended dishonorable discharge, or confinement in a penitentiary, with limited exceptions. The legislation further required legal review of other cases in the Office of the Judge Advocate General.
