After the attack on Pearl Harbor on December 7, 1941, President at the time Franklin Roosevelt issued two executive orders. One of them allowed the Secretary of War to designate certain parts of the country as military areas and to exclude certain persons from them.The other order established the War Relocation Authority which had the power to remove, maintain, and supervise persons who were excluded from the military zones.Gordon Hirabayashi was a student at the University of Washington at the time and got convicted of violating curfew and relocation order. He took this case to court and the question was did the President's executive orders and the power delegated to the military authorities discriminate against Americans and resident aliens of Japanese descent in violation of the Fifth Amendment? The court ruled unanimously against Hirabayashi saying that the Japanese felt strongly tied to their mother country and that the curfew was a necessary safety precaution.
