Katz v. United States

Katz v. United States was a 1967 decision by the United States Supreme Court case discussing the nature of the "right to privacy" and the legal definition of a "search." The Court’s ruling adjusted previous interpretations of the unreasonable search and seizure clause of the Fourth Amendment to count immaterial intrusion with technology as a search, overruling Olmstead v. United States and Goldman v. United States. Katz also restricted Fourth Amendment protection to all areas where a person has a "reasonable expectation of privacy."
