What policy did the supreme court upheld towards Japanese Americans?

The Supreme Court upheld the policy of internment of Japanese Americans during World War II in the 1944 case Korematsu v. United States. The Court ruled that the government's decision to place Japanese Americans in internment camps was a wartime necessity, citing national security concerns. This decision has since been heavily criticized for its endorsement of racial discrimination and violation of civil liberties. Subsequent legal and historical assessments have largely condemned the internment as unjust and unconstitutional.
