William O. Douglas,
Harisiades v. Shaughnessy & Mascitti…
“ Banishment may be resorted to as punishment for crime; but among the powers reserved to the people, and not delegated to the government, is that of determining whether whole classes in our midst shall, for no crime but that of their race and birthplace, be driven from our territory.'The right to be immune from arbitrary decrees of banishment certainly may be more important to 'liberty' than the civil rights which all aliens enjoy when they reside here. Unless they are free from arbitrary banishment, the 'liberty' they enjoy while they live here is indeed illusory. ”
