Gordon Hirabayashi, a 24-year-old senior at the University of Washington, arrived at the FBI office in Seattle on May 16, 1942, the date that he had been ordered to register for exclusion. He handed the FBI agent a four-page statement that explained why he refused to register. Hirabayashi was raised as a Quaker and trained as a pacifist, and his reasons for refusal stemmed from his religious convictions and pacifism. Hirabayashi was arrested and his case became an important test of the constitutionality of exclusion. In 1986, Hirabayashi's case was reopened and his convictions surrounding the incarceration were vacated by the Ninth Circuit Court of Appeals, arguing in part that, "racial bias was the cornerstone of the internment orders."
