Korematsu v. United States was a Supreme Court case that was decided on December 18, 1944, at the end of World War II. It involved the legality of Executive Order 9066, which ordered many Japanese-Americans to be placed in internment camps during the war.

Facts of Korematsu v. United States

In 1942, Franklin Roosevelt signed Executive Order 9066, allowing the U.S. military to declare parts of the U.S. as military areas and thereby exclude specific groups of people from them.

The practical application was that many Japanese-Americans were forced from their homes and placed in internment camps during World War II. Frank Korematsu, a U.S.-born man of Japanese descent, knowingly defied the order to be relocated and was arrested and convicted. His case went to the Supreme Court, where it was decided that exclusion orders based on Executive Order 9066 were in fact Constitutional. Therefore, his conviction was upheld.

The Court's Decision

The decision in the case was complicated and, many might argue, not without contradiction. While the Court acknowledged that citizens were being denied their constitutional rights, it also declared that the Constitution allowed for such restrictions. Justice Hugo Black wrote in the decision that "all legal restrictions which curtail the civil rights of a single racial group are immediately suspect." He also wrote that "Pressing public necessity may sometimes justify the existence of such restrictions." In essence, the Court majority decided that the security of the general citizenry of the US was more important than upholding the rights of a single racial group, during this time of military emergency.

Dissenters in the Court, including Justice Robert Jackson, argued that Korematsu had committed no crime, and therefore there were no grounds for restricting his civil rights. Robert also warned that the majority decision would have much more lasting and potentially damaging effects than Roosevelt's executive order.

The order would likely be lifted after the war, but the Court's decision would establish a precedent for denying rights of citizens if the current powers that be determine such action to be of "urgent need." 

Significance of Korematsu v. United States

The Korematsu decision was significant because it ruled that the United States government had the right to exclude and forcibly move people from designated areas based on their race. The decision was 6-3 that the need to protect the United States from espionage and other wartime acts was more important than Korematsu's individual rights. Even though Korematsu's conviction was eventually overturned in 1983, the Korematsu ruling concerning the creation of exclusion orders has never been overturned.

Korematsu's Critique of Guantanamo 

In 2004, at the age of 84, Frank Korematsu filed an amicus curiae, or friend of the court, brief in support of Guantanamo detainees who were fighting against being held as enemy combatants by the Bush Administration. He argued in his brief that the case was “reminiscent” of what had happened in the past, where the government too quickly took away individual civil liberties in the name of national security.
