The effect of Korematsu v. United States was that internment camps were affirmed as legal.
Korematsu v. United States was one of the key cases of the Supreme Court of the United States, where compliance with the Executive Order 9066 was considered, according to which Japanese-Americans were obliged to relocate to internment camps during the Second World War, regardless of their citizenship.
By a decision of 6 judges against 3, the Supreme Court agreed with the government, declaring that the order complies with the Constitution. The decision made by Judge Hugo Black ruled that the need for protection against espionage outweighed the individual rights of Fred Korematsu, as well as the rights of other Americans of Japanese origin.
