The landmark Supreme Court case of Katz v. United States, decided in 1967, marked a significant shift in the Court's interpretation of the Fourth Amendment's protection against unreasonable searches and seizures. This case has had a lasting impact on the development of privacy law in the United States, and its influence can still be felt today.
Background and Facts of the Case
In 1965, Charles Katz was investigated by the FBI for transmitting wagering information over the telephone. As part of their investigation, FBI agents attached a recording device to the outside of a public telephone booth that Katz was known to use. The device captured Katz’s conversations, which were later used as evidence against him in court. Katz was convicted and sentenced to prison, but he appealed his conviction, arguing that the recording of his conversations was a violation of his Fourth Amendment rights.
The Court’s Decision
The Supreme Court, in a 7-1 decision, ruled that the FBI’s actions did indeed constitute a search under the Fourth Amendment. The Court held that the Fourth Amendment protects people, not just places, and that a person has a reasonable expectation of privacy in a public telephone booth when making a call. This expectation of privacy is not limited to the physical space, but also extends to the conversation itself. The Court established a two-part test to determine whether a search has occurred: (1) does the individual have a subjective expectation of privacy, and (2) is that expectation one that society is prepared to recognize as reasonable?
