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. ”
