Katz v. United States (1967)

Charles Katz was convicted of conducting illegal gambling operations across state lines after transmitting wagering information via a public phone booth. The Federal Bureau of Investigation (FBI) used an electronic eavesdropping device attached to the phone booth used by Katz to listen in and record his conversations without a warrant. Katz argued that the unauthorized wiretap violated his constitutional right to privacy. Federal agents argued that the phone booth was public; therefore, it carries no expectation of privacy.

The Supreme Court ruled that Katz had justifiably relied on his constitutional right to privacy when making phone calls using the telephone booth with the door shut behind him and found that the wiretapping constituted as an unreasonable search and seizure (Katz v. United States, 1967).

Katz’s case was historic because it highlighted the right to privacy and what defines search and seizure of intangible property, such as electronic communications (Katz v. United States, 1967). Because of this case, investigators should be knowledgeable of the reasonable expectation of privacy test (“Katz test”) that is used to determine if an individual has a reasonable expectation of privacy. The reasonable expectation of privacy test has also been used in numerous cases where technology (and the advancement of technology) generates new questions on the expectations of privacy (Legal Information Institute, n.d.).
