Decision of the Court

The decision of the Supreme Court was delivered by Justice Hugo Black on December 18, 1984 on the Korematsu vs United States case where Justice Black states, “Exclusion Order No. 34, which the petitioner knowingly and admittedly violated, was one of a number of military orders and proclamations, all of which were substantially based upon Executive Order No. 9066, 7 Fed. Reg. 1407. That order, issued after we were at war with Japan, declared that "the successful prosecution of the war requires every possible protection against espionage and against sabotage to national-defense material, national-defense premises, and national-defense utilities. . . ." (http://www.law.umkc.edu/faculty/projects/ftrials/conlaw/korematsu.html)

It was for the reason that it was impossible for the United States Military to determine who is loyal and disloyal quick enough that it was in responsibility of the military with the authorization of the president to move and isolate any American citizen with Japanese ancestry. “In this case the petitioner challenges the assumptions upon which we rested our conclusions in the Hirabayashi case. He also urges that by May 1942, when Order No. 34 was promulgated, all danger of Japanese invasion of the West Coast had disappeared. After careful consideration of these contentions we are compelled to reject them.

Here, as in the Hirabayashi case, ". . . we cannot reject as unfounded the judgment of the military authorities and of Congress that there were disloyal members of that population, whose number and strength could not be precisely and quickly ascertained. We cannot say that the war-making branches of the Government did not have ground for believing that in a critical hour such persons could not readily be isolated and separately dealt with, and constituted a menace to the national defense and safety, which demanded that prompt and adequate measures be taken to guard against it."

Like curfew, exclusion of those of Japanese origin was deemed necessary because of the presence of an unascertained number of disloyal members of the group, most of whom we have no doubt were loyal to this country. It was because we could not reject the finding of the military authorities that it was impossible to bring about an immediate segregation of the disloyal from the loyal that we sustained the validity of the curfew order as applying to the whole group. In the instant case, temporary exclusion of the entire group was rested by the military on the same ground. The judgment that exclusion of the whole group was for the same reason a military imperative answers the contention that the exclusion was in the nature of group punishment based on antagonism to those of Japanese origin....” (http://caselaw.lp.findlaw.com/scripts/getcase.pl?court=US&vol=323&invol=214)

Justice Murphy dissented, declaring, “This exclusion of 'all persons of Japanese ancestry, both alien and non-alien,' from the Pacific Coast area on a plea of military necessity in the absence of martial law ought not to be approved. Such exclusion goes over 'the very brink of constitutional power' and falls into the ugly abyss of racism.” (http://caselaw.lp.findlaw.com/scripts/getcase.pl?court=US&vol=323&invol=214)

Justice Jackson also dissented, stating, “A citizen's presence in the locality, however, was made a crime only if his parents were of Japanese birth. Had Korematsu been one of four-the others being, say, a German alien enemy, an Italian alien enemy, and a citizen of American-born ancestors, convicted of treason but out on parole- only Korematsu's presence would have violated the order. The difference between their innocence and his crime would result, not from anything he did, said, or thought, different than they, but only in that he was born of different racial stock.

Now, if any fundamental assumption underlies our system, it is that guilt is personal and not inheritable. Even if all of one's antecedents had been convicted of treason, the Constitution forbids its penalties to be visited upon him, for it provides that 'no Attainder of Treason shall work Corruption of Blood, or Forfeiture except during the Life of the Person attained.' Article 3, 3, cl. 2. But here is an attempt to make an otherwise innocent act a crime merely because this prisoner is the son of parents as to whom he had no choice, and belongs to a race from which there is no way to resign. If Congress in peace-time legislation should [323 U.S. 214, 244] enact such a criminal law, I should suppose this Court would refuse to enforce it.” (http://caselaw.lp.findlaw.com/scripts/getcase.pl?court=US&vol=323&invol=214)
