Like Gordon Hirabayashi’s case, Fred Korematsu’s challenge of the constitutionality of internment camps was also denied. Not all the Supreme Court justices agreed, however. One of the dissenters in the Korematsu case was Justice Frank Murphy. A former governor of Michigan and a former attorney general of the United States, Murphy had established himself as a protector of civil liberties and a liberal voice on the Court. In the following excerpt from his Korematsu dissent, Murphy offers social and constitutional reasons for denying the legality of internment.

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.

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. 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 main reasons relied upon by those responsible for the forced evacuation, therefore, do not prove a reasonable relation between the group characteristics of Japanese Americans and the dangers of invasion, sabotage and espionage. The reasons appear, instead, to be largely an accumulation of much of the misinformation, half-truths and insinuations that for years have been directed against Japanese Americans by people with racial and economic prejudices—the same people who have been among the foremost advocates of the evacuation. . . .

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. . . .

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.
