Summary

Robert H. Jackson Johnson v. Eisentrager — Opinion of the Court

It would be difficult to devise more effective fettering of a field commander than to allow the very enemies he is ordered to reduce to submission to call him to account in his own civil courts and divert his efforts and attention from the military offensive abroad to the legal defensive at home. Nor is it unlikely that the result of such enemy litigiousness would be a conflict between judicial and military opinion highly comforting to enemies of the United States.

Robert H. Jackson Johnson v. Eisentrager — Opinion of the Court

Executive power over enemy aliens, undelayed and unhampered by litigation, has been deemed, throughout our history, essential to war-time security. This is in keeping with the practices of the most enlightened of nations and has resulted in treatment of alien enemies more considerate than that which has prevailed among any of our enemies and some of our allies.

Robert H. Jackson Johnson v. Eisentrager — Opinion of the Court

Because the Government's obligation of protection is correlative with the duty of loyal support inherent in the citizen's allegiance, Congress has directed the President to exert the full diplomatic and political power of the United States on behalf of any citizen, but of no other, in jeopardy abroad. When any citizen is deprived of his liberty by any foreign government, it is made the duty of the President to demand the reasons and, if the detention appears wrongful, to use means not amounting to acts of war to effectuate his release.
