Korematsu v. United States · ¶72

In the very nature of things, military decisions are not susceptible of intelligent judicial appraisal. They do not pretend to rest on evidence, but are made on information that often would not be admissible and on assumptions that could not be proved. Information in support of an order could not be disclosed to courts without danger that it would reach the enemy. Neither can courts act on communications made in confidence. Hence courts can never have any real alternative to accepting the mere declaration of the authority that issued the order that it was reasonably necessary from a military viewpoint.
