Summary

Portrait of Felix Frankfurter Felix Frankfurter Abel v. United States — Opinion of the Court

Nor is there any constitutional reason to limit the search for materials proving the deportability of an alien, when validly arrested, more severely than we limit the search for materials probative of crime when a valid criminal arrest is made. The need for the proof is as great in one case as in the other, for deportation can be accomplished only after a hearing at which deportability is established. Since a deportation arrest warrant is not a judicial warrant, a search incidental to a deportation arrest is without the authority of a judge or commissioner.

Statutes authorizing administrative arrest to achieve detention pending deportation proceedings have the sanction of time. It would emphasize the disregard for the presumptive respect the Court owes to the validity of Acts of Congress, especially when confirmed by uncontested historical legitimacy, to bring into question for the first time such a long-sanctioned practice of government at the behest of a party who not only did not challenge the exercise of authority below, but expressly acknowledged its validity.

Whether the Fourth and Fifth Amendments to the Constitution of the United States are violated by a search and the seizure of evidence without a search warrant, after an alien suspected and officially accused of espionage has been taken into custody for deportation, pursuant to an administrative Immigration Service warrant, but has not been arrested for the commission of a crime?
