Korematsu v. United States
On May 19, 1942, during World War II, Japanese Americans were ordered to be move into relocation camps by Civilian Restrictive Order No. 1, 8 Fed. Reg. 982. This order, and other similar orders, were based upon Executive Order 9066 (February 19, 1942). Fred Korematsu was a Japanese-American man who decided to stay in San Leandro, California and knowingly violated Civilian Exclusion Order No. 34 of the U.S. Army.  Korematsu argued that the Executive Order 9066 was unconstitutional and that it violated the Fifth Amendment to the United States Constitution. He was arrested, tried and convicted. No question was raised as to Korematsu's loyalty to the United States.  The Circuit Court of Appeals affirmed the conviction, and the Supreme Court granted certiorari.
