Introduction
Korematsu v. United States, 323 U.S. 214 (1944), stands as one of the most controversial and instructive cases in American constitutional history. The case arose from the United States government’s decision, during World War II, to forcibly relocate and intern over 110,000 Japanese Americans, most of whom were U.S. citizens. Fred Toyosaburo Korematsu, a young Japanese American, refused to comply with the internment order and was convicted for his defiance. His legal challenge to this conviction ultimately reached the Supreme Court, which, in a 6-3 decision, upheld the government’s actions as a wartime necessity.
This guide provides a comprehensive overview of the Korematsu case, examining its background, the Supreme Court’s decision, the legal reasoning involved, its immediate and long-term impacts, and its enduring legacy in American jurisprudence. By understanding Korematsu, legal professionals and scholars can better appreciate the delicate balance between civil liberties and national security—a balance that remains relevant in contemporary legal debates.
Background and Historical Context
Japanese American Internment During World War II
Following the attack on Pearl Harbor on December 7, 1941, the United States entered World War II amid widespread fear of espionage and sabotage by individuals of Japanese descent living on the West Coast. On February 19, 1942, President Franklin D. Roosevelt signed Executive Order 9066, authorizing the military to exclude any persons from designated areas as a security measure. This order led to the forced removal and incarceration of Japanese Americans in internment camps.
The rationale behind this policy was ostensibly military necessity, but subsequent historical analysis has shown that it was heavily influenced by racial prejudice, wartime hysteria, and political pressure. The government provided little to no evidence of actual espionage or sabotage by Japanese Americans. Nevertheless, families were uprooted, businesses lost, and communities shattered, often with only a few days’ notice.
Fred Korematsu’s Defiance
Fred Korematsu, a U.S.-born citizen of Japanese descent, chose to remain in his home in California, defying the exclusion order. He altered his appearance and identity in an attempt to avoid detection, but was eventually arrested and convicted for violating military orders. Korematsu challenged his conviction, arguing that the government’s actions violated his constitutional rights, particularly the Fifth Amendment guarantee of due process and the Fourteenth Amendment’s equal protection principles.
The Supreme Court Case
Procedural History
Korematsu’s legal battle began in the federal district court, where his conviction was upheld. The Ninth Circuit Court of Appeals affirmed the decision. The case then proceeded to the United States Supreme Court, where it was argued in October 1944 and decided on December 18, 1944.
The Supreme Court’s Decision
In a 6-3 majority opinion authored by Justice Hugo Black, the Supreme Court upheld Korematsu’s conviction. The Court reasoned that the exclusion order was not based on racial hostility, but on the need to protect against espionage and sabotage during wartime. The majority opinion stated:
"Compulsory exclusion of large groups of citizens from their homes, except under circumstances of direst emergency and peril, is inconsistent with our basic governmental institutions. But when under conditions of modern warfare our shores are threatened by hostile forces, the power to protect must be commensurate with the threatened danger."
— Justice Hugo Black, Korematsu v. United States, 323 U.S. 214 (1944)
The Court acknowledged the severity of the exclusion order but deferred to the military’s judgment, emphasizing that the judiciary was not equipped to second-guess military decisions in wartime.
Dissenting Opinions
Three justices—Justices Roberts, Murphy, and Jackson—issued powerful dissents, warning of the dangers of sanctioning racial discrimination by the government. Justice Frank Murphy’s dissent was especially forceful, describing the exclusion order as the "legalization of racism":
"Racial discrimination in any form and in any degree has no justifiable part whatever in our democratic way of life."
— Justice Frank Murphy, Dissent
Justice Robert Jackson’s dissent also highlighted the long-term dangers of the decision, warning that the precedent could be used to justify future violations of civil liberties:
"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."
Legal Reasoning and Constitutional Issues
The Doctrine of Deference to Military Authority
The majority in Korematsu relied heavily on the principle of judicial deference to the executive and military authorities during wartime. The Court held that, in times of "emergency and peril," the government’s need to protect national security could justify severe restrictions on individual rights. The Court’s reasoning was influenced by the notion that the judiciary should not interfere with military judgments, especially in matters involving national defense.
Strict Scrutiny and Racial Classifications
Although the Court purported to apply strict scrutiny—requiring that racial classifications be "immediately suspect" and subject to the "most rigid scrutiny"—it ultimately concluded that the exclusion order met this standard due to the "pressing public necessity." Critics argue that the Court’s application of strict scrutiny was superficial, as it failed to demand substantial evidence of actual threat posed by Japanese Americans.
Due Process and Equal Protection
Korematsu’s challenge was grounded in the Fifth Amendment’s due process clause and, by extension, the Fourteenth Amendment’s equal protection principles (as applied to the federal government). The majority’s decision effectively sanctioned the deprivation of liberty and property without individualized suspicion or due process, solely on the basis of race and national origin.
Immediate Impact and Aftermath
The Human Cost
The Supreme Court’s decision validated the ongoing internment of Japanese Americans, who remained in camps until 1945. The internment resulted in profound economic, social, and psychological harm. Families lost homes, businesses, and property, while enduring harsh conditions and stigma.
Later Legal Developments
In the decades following the war, the internment policy and the Korematsu decision were widely criticized. In 1983, Korematsu’s conviction was vacated by a federal district court in a coram nobis proceeding, after it was revealed that the government had withheld critical evidence from the Supreme Court—specifically, intelligence reports indicating that Japanese Americans posed no security threat. This legal victory did not overturn the Supreme Court’s original decision, but it did serve as a formal acknowledgment of the injustice.
Redress and Apology
In 1988, Congress passed the Civil Liberties Act of 1988, which formally apologized for the internment and provided reparations to surviving Japanese American internees. The Act recognized that the internment was the result of "race prejudice, war hysteria, and a failure of political leadership" rather than legitimate military necessity.

Modern Reassessment and Legacy
Scholarly Criticism
Legal scholars and civil rights advocates have almost universally condemned Korematsu as a deeply flawed decision. It is frequently cited as a cautionary example of how fear and prejudice can override constitutional protections, particularly for racial minorities. The case is often discussed alongside other infamous Supreme Court decisions, such as Dred Scott v. Sandford and Plessy v. Ferguson, as examples of judicial failures to protect minority rights.
The Supreme Court’s Repudiation
In 2018, the Supreme Court formally repudiated Korematsu in the case of Trump v. Hawaii. Writing for the majority, Chief Justice John Roberts stated:
"The forcible relocation of U.S. citizens to concentration camps, solely and explicitly on the basis of race, is objectively unlawful and outside the scope of Presidential authority. Korematsu was gravely wrong the day it was decided, has been overruled in the court of history, and—to be clear—'has no place in law under the Constitution.'"
This explicit rejection, while not technically overruling Korematsu (since the case was not directly before the Court), signaled a strong consensus that the decision was a constitutional aberration.
Continued Relevance
Despite its repudiation, Korematsu remains relevant as a warning against the dangers of unchecked government power during times of crisis. The case is frequently cited in debates over national security, immigration, and civil liberties, particularly when the government seeks to curtail individual rights in the name of public safety.
The National WWII Museum reflects on the case’s enduring significance, noting that:
"Korematsu v. United States continues to be an important reference point for discussions about civil rights, national security, and the limits of governmental authority."

Lessons for Legal Professionals
The Importance of Vigilance
Korematsu teaches that courts and lawyers must be vigilant in protecting civil liberties, especially for vulnerable minorities. The judiciary’s failure to check executive overreach in Korematsu is a sobering reminder of the consequences when the courts abdicate their role as guardians of constitutional rights.
The Dangers of Deference
The case also illustrates the dangers of excessive judicial deference to the executive branch, particularly in times of war or national emergency. While the government must have some flexibility to respond to threats, this power must be balanced against the fundamental rights enshrined in the Constitution.
The Value of Dissent
The powerful dissents in Korematsu have become a touchstone for later generations, demonstrating the importance of principled judicial opposition to injustice, even when the majority is swayed by fear or expediency.
Korematsu in Contemporary Jurisprudence
Use as Precedent
While Korematsu was never formally overruled until its repudiation in Trump v. Hawaii, it was rarely cited as precedent in later cases. Instead, it served as a negative example—a warning against the dangers of racial profiling and mass deprivation of liberty without due process.
Influence on Policy and Public Discourse
The case has influenced public discourse on issues such as the detention of terrorism suspects, immigration bans, and surveillance. Policymakers and advocates frequently invoke Korematsu to argue against policies that target specific racial, ethnic, or religious groups.
Education and Remembrance
Korematsu’s story is now part of educational curricula and public history, serving as a reminder of the fragility of civil liberties in times of fear. The annual Fred Korematsu Day of Civil Liberties and the Constitution, observed in several states, honors his legacy and the ongoing struggle for civil rights.
