Korematsu v. United States, Supreme Court of the United States (1944)
Korematsu is one of the most infamous Supreme Court decisions because it upheld the internment of Japanese Americans during World War II. It is remembered as a warning about how constitutional rights can collapse under wartime panic and racialized fear.
Fred Korematsu refused to comply with a wartime exclusion order requiring Japanese Americans to leave the West Coast. He was convicted for remaining in the restricted zone.
Information not available.
The Court considered the military exclusion order, the wartime threat narrative, and the race-based consequences of the policy.
Korematsu argued that the exclusion was racial discrimination and a denial of constitutional equality. The government argued that military necessity justified the measure.
The Court upheld the exclusion order.
The majority accepted the government’s wartime justification and applied a highly deferential approach to military judgments. Justice Murphy’s dissent condemned the decision as legalized racism.
Korematsu became the emblematic cautionary case against racial discrimination in wartime and was later repudiated in constitutional memory.

Can national security justify racial discrimination?
The United States and China both have constitutional courts that have faced the tension between national security and individual rights, but with very different outcomes. Korematsu (1944) upheld the internment of Japanese Americans, while China's courts have generally prioritized state security over individual rights.
China's approach to national security and individual rights provides a stark contrast to U.S. wartime civil liberties issues. Why preferable to others: India, UK, and France have different historical contexts; Russia has some parallels but less stark contrast.
Each system arrived at the same problem from a different direction: how to balance security and liberty in times of crisis. In the U.S., the Court infamously upheld racial exclusion during World War II. In China, the courts have generally deferred to state security concerns.

Both systems recognize that national security can create pressure to restrict rights, and both courts have faced the question of how far the government can go. In both countries, these cases have become cautionary tales about judicial failure.
The paths diverge sharply, but both are cautionary. In the United States, Korematsu upheld the internment of Japanese Americans, reasoning that military necessity justified racial exclusion. The decision is now widely repudiated. In China, by contrast, courts have generally deferred to state security concerns, prioritizing national security over individual rights. Chinese courts do not have the same tradition of repudiating past decisions, creating a different kind of judicial culture.
The practical lesson is that courts can fail under pressure, but they can also learn. In the U.S., Korematsu is a permanent stain. In China, the deference to state security continues. For citizens, both systems provide rights protections, but the track record is mixed.
Korematsu v. United States and China's national security cases both gave judges the power to protect rights in crisis, but they used that power very differently. One failed and was repudiated; the other continues to defer. Together, they show that courts are not just interpreters—they are guardians of constitutional conscience.
