Brief Fact Summary. The petitioner, Katz (the “petitioner”), was convicted of transmitting wagering information over telephone lines in violation of federal law. The government had entered into evidence the petitioner’s end of telephone conversations that the government had obtained by placing a listening device to the phone booth that the petitioner used. The Court of Appeals rejected the petitioner’s contention that the evidence should be suppressed.
Synopsis of Rule of Law. The protection of the Fourth Amendment of the United States Constitution (“Constitution”), against unreasonable searches and seizures, follows the person and not the place.
Issue. Whether the Fourth Amendment of the Constitution protects telephone conversations conducted in a phone booth and secretly recorded from introduction as evidence against a person?
Held. Justice Potter Stewart filed the majority opinion. The petitioner strenuously asserted that the phone booth was a constitutionally protected area. However, the Fourth Amendment protects persons and not places from unreasonable intrusion. Even in a public place, a person may have a reasonable expectation of privacy in his person. Although the petitioner did not seek to hide his self from public view when he entered the telephone booth, he did seek to keep out the uninvited ear. He did not relinquish his right to do so simply because he went to a place where he could be seen. A person who enters into a telephone booth may expect the protection of the Fourth Amendment of the Constitution as he assumes that the words he utters into the telephone will not be broadcast to the world. Once this is acknowledged, it is clear that the Fourth Amendment of the Constitution protects persons and not areas from unreasonable searches and seizures. The Government’s activities in electronically listening to and recording the petitioner’s telephone conversations constituted a search and seizure under the Fourth Amendment and absent a search warrant predicated upon sufficient probable cause, all evidence obtained is inadmissible.
Even though petitioner acted with restraint in conducting the search, the inescapable fact is that this restraint was imposed by the agents themselves, not by a judicial officer.View Full Point of Law
Concurrence. Justice John Harlan (“J. Harlan”) filed a dissenting opinion. The Fourth Amendment of the Constitution protects persons, not places. There is a twofold requirement for what protection is afforded to those people. First, that a person has exhibited an actual expectation of privacy and, second, that the expectation be one that society is prepared to recognize as reasonable. The critical fact in this case is that a person who enters a telephone booth shuts the door behind him, pays the toll, and is surely entitled to assume that his conversation is not being intercepted. On the other hand, conversations out in the open public would not be protected against being overheard as the expectation of privacy would not be reasonable.
Discussion. The Fourth Amendment of the Constitution provides constitutional protection to individuals and not to particular places. The two-part test for this protection is introduced by J. Harlan. First, the person must have exhibited an actual expectation of privacy and, second, that expectation must be reasonable.
