Korematsu V. United States - Decision

Decision

The decision of the case, written by Justice Hugo Black, found the case largely indistinguishable from the previous year's Hirabayashi v. United States decision, and rested largely on the same principle: deference to Congress and the military authorities, particularly in light of the uncertainty following Pearl Harbor. Justice Black further denied that the case had anything to do with racial prejudice:

Korematsu was not excluded from the Military Area because of hostility to him or his race. He was excluded because we are at war with the Japanese Empire, because the properly constituted military authorities feared an invasion of our West Coast and felt constrained to take proper security measures, because they decided that the military urgency of the situation demanded that all citizens of Japanese ancestry be segregated from the West Coast temporarily, and, finally, because Congress, reposing its confidence in this time of war in our military leaders — as inevitably it must — determined that they should have the power to do just this.
