In Burns v. Wilson, 346 U.S. 137 (1953), the Court reiterated the rule that the scope of habeas corpus has always been narrower in military cases than when a prisoner is in civil custody. That case permitted review of a court-martial conviction for claimed violations of constitutional due process where the military justice system had failed to fully consider such claims. Except for constitutional violations, however, relief is proper only if the military had no jurisdiction to take the action complained of.
