Korematsu v. United States: Japanese Internment and SCOTUS
This paper examines the U.S. Supreme Court's 1944 decision in Korematsu v. United States, in which the Court upheld the wartime internment of Japanese-Americans on national security grounds. The paper analyzes the majority opinion's reliance on military deference and wartime necessity, the constitutional weaknesses of that reasoning, and the powerful dissenting opinions of Justices Murphy and Roberts. It further critiques the racially discriminatory double standard applied to Japanese-Americans versus German- and Italian-Americans and argues that the decision violated the Fourteenth Amendment's due process guarantees. The paper concludes by drawing lessons from the case relevant to post-9/11 civil liberties debates.

What makes this paper effective
- The paper directly quotes from both the majority opinion and the dissents, grounding its critique in the Court's own language rather than relying solely on the author's assertions.
- It draws a pointed comparative argument — the disparate treatment of Japanese-Americans versus German- and Italian-Americans — which exposes the racial, rather than security-based, logic of the decision.
- The conclusion extends the historical analysis to a contemporary context (post-9/11 profiling), demonstrating the case's ongoing relevance without overstating the comparison.
Key academic technique demonstrated
The paper uses counterpoint structure effectively: it presents the majority's position, then systematically dismantles it using the dissenting justices' own words. This technique — allowing the opposition to speak before rebutting it — is a strong model of evidence-based legal argumentation.
Structure breakdown
The essay opens with a broad historical framing that contextualizes the internment alongside other American civil rights failures. It then moves through the majority opinion, its constitutional justification, and its racial double standard, before turning to the dissents as the moral and legal corrective. A brief concluding paragraph synthesizes the critique and applies it forward. Five clear thematic sections give the essay a logical, easy-to-follow progression appropriate for an undergraduate legal studies essay.
Introduction: Internment as a Historical Injustice
The internment of Japanese-Americans is considered one of the "black marks" upon American history, much like the expulsion of Native American tribes from their historical lands and the institution of slavery. Not only was the act of interning individuals — children and the elderly as well as adults — simply because of their race an affront to human rights, it is even more shocking and disappointing that the majority of the U.S. Supreme Court did nothing to stop it and even sanctioned the government's actions. The majority decision was grounded in a concept of "national security," which would later be invoked many times by the government to curtail individual liberties in the name of preserving democracy.
Ironically, in the government's efforts to preserve democracy, rights were trampled and the U.S. stance reflected the very racism that was characteristic of the Nazis it was fighting. This can be seen in the majority decision of Korematsu v. United States, in which the American-born Fred T. Korematsu refused to report to an internment camp and challenged the constitutionality of the federal directive mandating he do so.
The Majority Opinion: National Security Over Individual Rights
Justices Black and Frankfurter, although acknowledging the serious questions that arise when creating laws promoting racial discrimination, ultimately argued that "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" (2). In the wake of the bombing of Pearl Harbor, there was intense fear that Japan would attack the mainland. The writings of the Court indicated that national security outweighed the rights of Japanese-American citizens.
Constitutional Weaknesses in the Majority's Reasoning
Little constitutional support could be provided for the opinion, except for the vague assertion by Justice Frankfurter: "The provisions of the Constitution which confer on the Congress and the President powers to enable this country to wage war are as much part of the Constitution as provisions looking to a nation at peace" (3). Even while acknowledging that the expulsions of Japanese-Americans were inconsistent with American principles, the authors of the majority decision argued that the threat from abroad was "too great."
This vague, amorphous threat posed by Japanese-Americans to the West Coast was, of course, not similarly perceived in the faces of Caucasian German-Americans, against whose nation the U.S. was also in military conflict. As eloquently expressed in the dissent by Justice Murphy: "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" (4). This was unconstitutional racism depriving citizens of due process under the Fourteenth Amendment, not grounded in any concrete intelligence information.
