Korematsu was born on our soil, of parents born in Japan. The Constitution makes him a citizen of the United States by nativity and a citizen of California by residence. No claim is made that he is not loyal to this country. There is no suggestion that apart from the matter involved here he is not law abiding and well disposed. Korematsu, however, has been convicted of an act not commonly a crime. It consists merely of being present in the state whereof he is a citizen, near the place where he was born, and where all his life he has lived. […] [H]is crime would result, not from anything he did, said, or thought, different than they, but only in that he was born of different racial stock. Now, if any fundamental assumption underlies our system, it is that guilt is personal and not inheritable. Even if all of one’s antecedents had been convicted of treason, the Constitution forbids its penalties to be visited upon him. But here is an attempt to make an otherwise innocent act a crime merely because this prisoner is the son of parents as to whom he had no choice, and belongs to a race from which there is no way to resign. If Congress in peace-time legislation should enact such a criminal law, I should suppose this Court would refuse to enforce it.
