TOYOSABURO KOREMATSU V. UNITED STATES.

Argued Oct. 11, 12, 1944.

Decided Dec. 18, 1944.

Mr. Justice Black delivered the opinion of the Court.

The petitioner, an American citizen of Japanese descent, was convicted in a federal district court for remaining in San Leandro, California, a ''Military Area,'' contrary to Civilian Exclusion Order No. 34 of the Commanding General of the Western Command, U.S. Army, which directed that after May 9, 1942, all persons of Japanese ancestry should be excluded from that area. No question was raised as to petitioner's loyalty to the United States. The Circuit Court of Appeals affirmed, and the importance of the constitutional question involved caused us to grant certiorari.

[1, 2] It should be noted, to begin with, that all legal restrictions which curtail the civil rights of a single racial group are immediately suspect. That is not to say that all such restrictions are unconstitutional. It is to say that courts must subject them to the most rigid scrutiny. Pressing public necessity may sometimes justify the existence of such restrictions; racial antagonism never can.

In the instant case prosecution of the petitioner was begun by information charging violation of an Act of Congress, of March 21, 1942, 56 Stat. 173, 18 U.S.C.A. Section 97a, which provides that ''* * * whoever shall enter, remain in, leave, or commit any act in any military area or military zone prescribed, under the authority of an Executive order of the President, by the Secretary of War, or by any military commander designated by the Secretary of War, contrary to the restrictions applicable to any such area or zone or contrary to the order of the Secretary of War or any such military commander, shall, if it appears that he knew or should have known of the existence and extent of the restrictions or order and that his act was in violation thereof, be guilty of a misdemeanor and upon conviction shall be liable to a fine of not to exceed $5,000 or to imprisonment for not more than one year, or both, for each offense.''

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. * * *''

One of the series of orders and proclamations, a curfew order, which like the exclusion order here was promulgated pursuant to Executive Order 9066, subjected all persons of Japanese ancestry in prescribed West Coast military areas to remain in their residences from 8 p.m. to 6 a.m. As is the case with the exclusion order here, that prior curfew order was designed as a ''protection against espionage and against sabotage.'' In Kiyoshi Hirabayashi v. United States, 320 U.S. 81, 63 S.Ct. 1375, 87 L.Ed. 1774, we sustained a conviction obtained for violation of the curfew order. The Hirabayashi conviction and this one thus rest on the same 1942 Congressional Act and the same basic executive and military orders, all of which orders were aimed at the twin dangers of espionage and sabotage.

The 1942 Act was attacked in the Hirabayashi case as an unconstitutional delegation of power; it was contended that the curfew order and other orders on which it rested were beyond the war powers of the Congress, the military authorities and of the President, as Commander in Chief of the Army; and finally that to apply the curfew order against none but citizens of Japanese ancestry amounted to a constitutionally prohibited discrimination solely on account of race. To these questions, we gave the serious consideration which their importance justified. We upheld the curfew order as an exercise of the power of the government to take steps necessary to prevent espionage and sabotage in an area threatened by Japanese attack.

[3] In the light of the principles we announced in the Hirabayashi case, we are unable to conclude that it was beyond the war power of Congress and the Executive to exclude those of Japanese ancestry from the West Coast war area at the time they did. True, exclusion from the area in which one's home is located is a far greater deprivation than constant confinement to the home 8 p.m. to 6 a.m. Nothing short of apprehension by the proper military authorities of the gravest imminent danger to the public safety can constitutionally justify either. But exclusion from a threatened area, no less than curfew, has a definite and close relationship to the prevention of espionage and sabotage. The military authorities, charged with the primary responsibility of defending our shores, concluded that curfew provided inadequate protection and ordered exclusion. They did so, as pointed out in our Hirabayashi opinion, in accordance with Congressional authority to the military to say who should, and who should not, remain in the threatened areas.
