Answer:
In the Korematsu v. United States decision, the Supreme Court did not uphold the inconstiutionality of the Japanese Internment Camps upon Executive Order 9066.
Locking people up of Japanese decent for "military necessity" as it was deemed a crime against humanity later on by U.S. officials and was racist.
This broke the 6th amendment for which the Japanese people were locked up in cramped cabins which were surrounded by armed officers and barbed wires 24/7, being locked up for being guilty until proven innocent.
From which also broke the fourteenth amendment which garenteed the due process of law which japanese people were locked up if they didnt comply with orders or if they did, were sent in camps.
