“this supposed civil libertarian also wrote the majority opinion upholding concentration camps for innocent American citizens. And Black did not even express any public regret over his Korematsu ruling in the decades to come. “It is noteworthy,” the legal scholar Stanley Kutner once observed, “that in an interview shortly before his death, Justice Black maintained that both the President and the Court had been right in their wartime actions.”
According to Black, the outcome in Korematsu was dictated by the existence of emergency conditions and the resulting judicial deference owed to the executive branch. “The military authorities considered the need for action was great, and time was short,” Black declared. “We cannot—by availing ourselves of the calm perspective of hindsight—now say that at that time these actions were unjustified.”
Writing in dissent, Justice Frank Murphy, another Roosevelt appointee and ardent New Dealer, argued that the president’s actions were, in fact, clearly unjustified at the time he took them. “It is essential that there be definite limits to military discretion, especially where martial law has not been declared,” Murphy wrote. “Individuals must not be left impoverished of their constitutional rights on a plea of military necessity that has neither substance nor support.””
