Korematsu v. the United States was a case on the constitutionality of having internment camps for Japanese Americans at the West Coast. It was discussed on the case that this was racial discrimination to implement this during the war. Korematsu filed a writ of coram nobis which calls to change a previous court decision. On the decision Justice Hugo Black explained that it was not about racial discrimination but an action by the military due to the urgency of the situation that made them decide. It did not present a justifiable solution to address the problem in security.
