William O. Douglas,
O'Callahan v. Parker — Opinion of the Court
“ These cases decide that courts-martial have no jurisdiction to try those who are not members of the Armed Forces, no matter how intimate the connection between their offense and the concerns of military discipline. From these cases, the Government invites us to draw the conclusion that once it is established that the accused is a member of the Armed Forces, lack of relationship between the offense and identifiable military interests is irrelevant to the jurisdiction of a court-martial. ”
