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.

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. 97a, which provides that

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, 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.

***

Here, as in the Hirabayashi case, supra, 320 U.S. at page 99, 63 S.Ct. at page 1385, '... 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. That there were members of the group who retained loyalties to Japan has been confirmed by investigations made subsequent to the exclusion. Approximately five thousand American citizens of Japanese ancestry refused to swear unqualified allegiance to the United States and to renounce allegiance to the Japanese Emperor, and several thousand evacuees requested repatriation to Japan.

***

…It is now argued that the validity of the exclusion order cannot be considered apart from the orders requiring him, after departure from the area, to report and to remain in an assembly or relocation center. The contention is that we must treat these separate orders as one and inseparable; that, for this reason, if detention in the assembly or relocation center would have illegally deprived the petitioner of his liberty, the exclusion order and his conviction under it cannot stand.

***

Since the petitioner has not been convicted of failing to report or to remain in an assembly or relocation center, we cannot in this case determine the validity of those separate provisions of the order. It is sufficient here for us to pass upon the order which petitioner violated. To do more would be to go beyond the issues raised, and to decide momentous questions not contained within the framework of the pleadings or the evidence in this case. It will be time enough to decide the serious constitutional issues which petitioner seeks to raise when an assembly or relocation order is applied or is certain to be applied to him, and we have its terms before us.

Some of the members of the Court are of the view that evacuation and detention in an Assembly Center were inseparable. After May 3, 1942, the date of Exclusion Order No. 34, Korematsu was under compulsion to leave the area not as he would choose but via an Assembly Center. The Assembly Center was conceived as a part of the machinery for group evacuation. The power to exclude includes the power to do it by force if necessary. And any forcible measure must necessarily entail some degree of detention or restraint whatever method of removal is selected. But whichever view is taken, it results in holding that the order under which petitioner was convicted was valid.

It is said that we are dealing here with the case of imprisonment of a citizen in a concentration camp solely because of his ancestry, without evidence or inquiry concerning his loyalty and good disposition towards the United States. Our task would be simple, our duty clear, were this a case involving the imprisonment of a loyal citizen in a concentration camp because of racial prejudice. Regardless of the true nature of the assembly and relocation centers-and we deem it unjustifiable to call them concentration camps with all the ugly connotations that term implies-we are dealing specifically with nothing but an exclusion order. To cast this case into outlines of racial prejudice, without reference to the real military dangers which were presented, merely confuses the issue. Korematsu was not excluded from the Military Area because of hostility to him or his race. He was excluded because we are at war with the Japanese Empire, because the properly constituted military authorities feared an invasion of our West Coast and felt constrained to take proper security measures, because they decided that the military urgency of the situation demanded that all citizens of Japanese ancestry be segregated from the West Coast temporarily, and finally, because Congress, reposing its confidence in this time of war in our military leaders-as inevitably it must-determined that they should have the power to do just this. There was evidence of disloyalty on the part of some, the military authorities considered that the need for action was great, and time was short. We cannot-by availing ourselves of the calm perspective of hindsight-now say that at that time these actions were unjustified.

AFFIRMED.

[Concurring opinion of Justice FRANKFURTER omitted.]

Mr. Justice ROBERTS.

I dissent, because I think the indisputable facts exhibit a clear violation of Constitutional rights.

This is not a case of keeping people off the streets at night as was Kiyoshi Hirabayashi v. United States, nor a case of temporary exclusion of a citizen from an area for his own safety or that of the community, nor a case of offering him an opportunity to go temporarily out of an area where his presence might cause danger to himself or to his fellows. On the contrary, it is the case of convicting a citizen as a punishment for not submitting to imprisonment in a concentration camp, based on his ancestry, and solely because of his ancestry, without evidence or inquiry concerning his loyalty and good disposition towards the United States. If this be a correct statement of the facts disclosed by this record, and facts of which we take judicial notice, I need hardly labor the conclusion that Constitutional rights have been violated.

The Government's argument, and the opinion of the court, in my judgment, erroneously divide that which is single and indivisible and thus make the case appear as if the petitioner violated a Military Order, sanctioned by Act of Congress, which excluded him from his home, by refusing voluntarily to leave and, so, knowingly and intentionally, defying the order and the Act of Congress.

***

…[T]he petitioner, prior to his arrest, was faced with two diametrically contradictory orders given sanction by the Act of Congress of March 21, 1942. The earlier of those orders made him a criminal if he left the zone in which he resided; the later made him a criminal if he did not leave.

I had supposed that if a citizen was constrained by two laws, or two orders having the force of law, and obedience to one would violate the other, to punish him for violation of either would deny him due process of law. And I had supposed that under these circumstances a conviction for violating one of the orders could not stand.

…The two conflicting orders, one which commanded him to stay and the other which commanded him to go, were nothing but a cleverly devised trap to accomplish the real purpose of the military authority, which was to lock him up in a concentration camp…

I would reverse the judgment of conviction.

Mr. Justice MURPHY, dissenting.

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.

In dealing with matters relating to the prosecution and progress of a war, we must accord great respect and consideration to the judgments of the military authorities who are on the scene and who have full knowledge of the military facts. The scope of their discretion must, as a matter of necessity and common sense, be wide. And their judgments ought not to be overruled lightly by those whose training and duties ill-equip them to deal intelligently with matters so vital to the physical security of the nation.

At the same time, however, it is essential that there be definite limits to military discretion, especially where martial law has not been declared. Individuals must not be left impoverished of their constitutional rights on a plea of military necessity that has neither substance nor support. Thus, like other claims conflicting with the asserted constitutional rights of the individual, the military claim must subject itself to the judicial process of having its reasonableness determined and its conflicts with other interests reconciled. 'What are the allowable limits of military discretion, and whether or not they have been overstepped in a particular case, are judicial questions.' Sterling v. Constantin, 287 U.S. 378, 401, 53 S.Ct. 190, 196.

The judicial test of whether the Government, on a plea of military necessity, can validly deprive an individual of any of his constitutional rights is whether the deprivation is reasonably related to a public danger that is so 'immediate, imminent, and impending' as not to admit of delay and not to permit the intervention of ordinary constitutional processes to alleviate the danger. United States v. Russell, 13 Wall. 623, 627, 628; Mitchell v. Harmony, 13 How. 115, 134, 135; Raymond v. Thomas, 91 U.S. 712, 716. Civilian Exclusion Order No. 34, banishing from a prescribed area of the Pacific Coast 'all persons of Japanese ancestry, both alien and non-alien,' clearly does not meet that test. Being an obvious racial discrimination, the order deprives all those within its scope of the equal protection of the laws as guaranteed by the Fifth Amendment. It further deprives these individuals of their constitutional rights to live and work where they will, to establish a home where they choose and to move about freely. In excommunicating them without benefit of hearings, this order also deprives them of all their constitutional rights to procedural due process. Yet no reasonable relation to an 'immediate, imminent, and impending' public danger is evident to support this racial restriction which is one of the most sweeping and complete deprivations of constitutional rights in the history of this nation in the absence of martial law.

***

That this forced exclusion was the result in good measure of this erroneous assumption of racial guilt rather than bona fide military necessity is evidenced by the Commanding General's Final Report on the evacuation from the Pacific Coast area. In it he refers to all individuals of Japanese descent as 'subversive,' as belonging to 'an enemy race' whose 'racial strains are undiluted,' and as constituting 'over 112,000 potential enemies ... at large today' along the Pacific Coast. In support of this blanket condemnation of all persons of Japanese descent, however, no reliable evidence is cited to show that such individuals were generally disloyal, or had generally so conducted themselves in this area as to constitute a special menace to defense installations or war industries, or had otherwise by their behavior furnished reasonable ground for their exclusion as a group.

***

The military necessity which is essential to the validity of the evacuation order thus resolves itself into a few intimations that certain individuals actively aided the enemy, from which it is inferred that the entire group of Japanese Americans could not be trusted to be or remain loyal to the United States. No one denies, of course, that there were some disloyal persons of Japanese descent on the Pacific Coast who did all in their power to aid their ancestral land. Similar disloyal activities have been engaged in by many persons of German, Italian and even more pioneer stock in our country. But to infer that examples of individual disloyalty prove group disloyalty and justify discriminatory action against the entire group is to deny that under our system of law individual guilt is the sole basis for deprivation of rights. Moreover, this inference, which is at the very heart of the evacuation orders, has been used in support of the abhorrent and despicable treatment of minority groups by the dictatorial tyrannies which this nation is now pledged to destroy. To give constitutional sanction to that inference in this case, however well- intentioned may have been the military command on the Pacific Coast, is to adopt one of the cruelest of the rationales used by our enemies to destroy the dignity of the individual and to encourage and open the door to discriminatory actions against other minority groups in the passions of tomorrow. No adequate reason is given for the failure to treat these Japanese Americans on an individual basis by holding investigations and hearings to separate the loyal from the disloyal, as was done in the case of persons of German and Italian ancestry. See House Report No. 2124 (77th Cong., 2d Sess.) 247-52. It is asserted merely that the loyalties of this group 'were unknown and time was of the essence.' Yet nearly four months elapsed after Pearl Harbor before the first exclusion order was issued; nearly eight months went by until the last order was issued; and the last of these 'subversive' persons was not actually removed until almost eleven months had elapsed. Leisure and deliberation seem to have been more of the essence than speed. And the fact that conditions were not such as to warrant a declaration of martial law adds strength to the belief that the factors of time and military necessity were not as urgent as they have been represented to be.

***

I dissent, therefore, from this legalization of racism. Racial discrimination in any form and in any degree has no justifiable part whatever in our democratic way of life. It is unattractive in any setting but it is utterly revolting among a free people who have embraced the principles set forth in the Constitution of the United States. All residents of this nation are kin in some way by blood or culture to a foreign land. Yet they are primarily and necessarily a part of the new and distinct civilization of the United States. They must accordingly be treated at all times as the heirs of the American experiment and as entitled to all the rights and freedoms guaranteed by the Constitution.

Mr. Justice JACKSON, dissenting.

Korematsu was born on our soil, of parents born in Japan. The Constitution makes him a citizen of the United States by nativity and a citizen of California by residence. No claim is made that he is not loyal to this country. There is no suggestion that apart from the matter involved here he is not law- abiding and well disposed. Korematsu, however, has been convicted of an act not commonly a crime. It consists merely of being present in the state whereof he is a citizen, near the place where he was born, and where all his life he has lived.

Even more unusual is the series of military orders which made this conduct a crime. They forbid such a one to remain, and they also forbid him to leave. They were so drawn that the only way Korematsu could avoid violation was to give himself up to the military authority. This meant submission to custody, examination, and transportation out of the territory, to be followed by indeterminate confinement in detention camps.

***

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 enact such a criminal law, I should suppose this Court would refuse to enforce it.

But the 'law' which this prisoner is convicted of disregarding is not found in an act of Congress, but in a military order. Neither the Act of Congress nor the Executive Order of the President, nor both together, would afford a basis for this conviction. It rests on the orders of General DeWitt. And it is said that if the military commander had reasonable military grounds for promulgating the orders, they are constitutional and become law, and the Court is required to enforce them. There are several reasons why I cannot subscribe to this doctrine.

It would be impracticable and dangerous idealism to expect or insist that each specific military command in an area of probable operations will conform to conventional tests of constitutionality. When an area is so beset that it must be put under military control at all, the paramount consideration is that its measures be successful, rather than legal. The armed services must protect a society, not merely its Constitution. The very essence of the military job is to marshal physical force, to remove every obstacle to its effectiveness, to give it every strategic advantage. Defense measures will not, and often should not, be held within the limits that bind civil authority in peace. No court can require such a commander in such circumstances to act as a reasonable man; he may be unreasonably cautious and exacting. Perhaps he should be. But a commander in temporarily focusing the life of a community on defense is carrying out a military program; he is not making law in the sense the courts know the term. He issues orders, and they may have a certain authority as military commands, although they may be very bad as constitutional law.

But if we cannot confine military expedients by the Constitution, neither would I distort the Constitution to approve all that the military may deem expedient. This is what the Court appears to be doing, whether consciously or not. I cannot say, from any evidence before me, that the orders of General DeWitt were not reasonably expedient military precautions, nor could I say that they were. But even if they were permissible military procedures, I deny that it follows that they are constitutional. If, as the Court holds, it does follow, then we may as well say that any military order will be constitutional and have done with it.

The limitation under which courts always will labor in examining the necessity for a military order are illustrated by this case. How does the Court know that these orders have a reasonable basis in necessity? No evidence whatever on that subject has been taken by this or any other court. There is sharp controversy as to the credibility of the DeWitt report. So the Court, having no real evidence before it, has no choice but to accept General DeWitt's own unsworn, self-serving statement, untested by any cross-examination, that what he did was reasonable. And thus it will always be when courts try to look into the reasonableness of a military order.

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.

Much is said of the danger to liberty from the Army program for deporting and detaining these citizens of Japanese extraction. But a judicial construction of the due process clause that will sustain this order is a farm more subtle blow to liberty than the promulgation of the order itself. A military order, however unconstitutional, is not apt to last longer than the military emergency. Even during that period a succeeding commander may revoke it all. But once a judicial opinion rationalizes such an order to show that it conforms to the Constitution, or rather rationalizes the Constitution to show that the Constitution sanctions such an order, the Court for all time has validated the principle of racial discrimination in criminal procedure and of transplanting American citizens. The principle then lies about like a loaded weapon ready for the hand of any authority that can bring forward a plausible claim of an urgent need. Every repetition imbeds that principle more deeply in our law and thinking and expands it to new purposes. All who observe the work of courts are familiar with what Judge Cardozo described as 'the tendency of a principle to expand itself to the limit of its logic.' A military commander may overstep the bounds of constitutionality, and it is an incident. But if we review and approve, that passing incident becomes the doctrine of the Constitution. There it has a generative power of its own, and all that it creates will be in its own image. Nothing better illustrates this danger than does the Court's opinion in this case.

***

My duties as a justice as I see them do not require me to make a military judgment as to whether General DeWitt's evacuation and detention program was a reasonable military necessity. I do not suggest that the courts should have attempted to interfere with the Army in carrying out its task. But I do not think they may be asked to execute a military expedient that has no place in law under the Constitution. I would reverse the judgment and discharge the prisoner.
