Harisiades v. Shaughnessy, District Director of Immigration and Naturalization

Opinion summary

Etalia.ai summary of the majority opinion

The U.S. Supreme Court case Harisiades v. Shaughnessy in 1951 revolved around the issue of whether or not a naturalized American citizen could be deported due to political affiliations prior to their naturalization. The petitioner, Mr. Harisiades, was a Greek immigrant who had become an American citizen but faced deportation because of his previous membership in the Communist Party before becoming a citizen. He argued that this violated his rights under the Due Process Clause and also constituted ex post facto lawmaking as he ceased being part of such organization before it was deemed illegal by Congress' Internal Security Act (1940). However, the court ruled against him with six votes to three stating that Congress has broad power over immigration matters and can deport citizens for past actions if they are considered potentially harmful to national security even after they have been granted citizenship.

In the dissenting opinion for Harisiades v. Shaughnessy, Justice William O. Douglas argued that the power to deport a naturalized citizen should not be absolute and unchecked. He contended that such authority could potentially lead to abuses of power by Congress or other government entities, particularly in times of political unrest or fear. Furthermore, he asserted that once an individual has been granted citizenship, they should have all the rights and protections afforded to native-born citizens under the Constitution - including protection from arbitrary deportation based on past actions or affiliations which were legal at the time they occurred but later criminalized. In essence, Douglas believed it was fundamentally unjust and contrary to American principles of fairness and due process for someone who had legally become a U.S citizen to then be stripped of their status because of retroactive changes in law.
