In Abel v. United States, 362 U.S. 217, 80 S.Ct. 683, 4 L.Ed.2d 668 (1960), the Court held that the defendant had no constitutional protection against the search of a hotel room he had relinquished and against the seizure of articles he had there abandoned. Mr. Justice Frankfurter said: 'As such, however, it was entirely lawful, although undertaken without a warrant. This is so for the reason that at the time of the search petitioner had vacated the room. The hotel then had the exclusive right to its possession, and the hotel management freely gave its consent that the search be made. Nor was it unlawful to seize the entire contents of the wastepaper basket, even though some of its contents had no connection with crime. So far as the record shows, petitioner had abandoned these articles. He had thrown them away. So far as he was concerned, they were bona vacantia. There can be nothing unlawful in the Government's appropriation of such abandoned property.' (Id. at 362 U.S. 241, 80 S.Ct. 698.)
