Whether federal officers’ warrantless interception of telephone conversations, accomplished without a physical trespass into the defendants’ premises, was an unreasonable search or seizure under the Fourth Amendment.
Holding
No. The wiretapping was not a search or seizure within the Fourth Amendment as it was then understood.
Reasoning
The Fourth Amendment protects persons, houses, papers, and effects against unreasonable searches and seizures. Its text, including its warrant requirement, addresses searches for and seizures of tangible things. Here, the officers neither entered the defendants’ homes or offices nor took possession of papers, effects, or other tangible property.
The agents obtained the evidence through hearing voluntarily spoken conversations carried over telephone wires outside the defendants’ premises. The Court treated the wires beyond a home or office as no more part of that protected place than the public highways along which the wires ran. In the Court’s view, listening to projected voices was not a constitutional search or seizure.
The Court distinguished decisions excluding evidence obtained through physical invasions or takings, including Weeks, Silverthorne, Amos, and Gouled. Those cases involved an official intrusion into protected premises, the taking of papers or effects, or their equivalent. The Court refused to extend Gouled’s rule beyond its particular facts.
The Court also rejected the analogy to sealed mail. A sealed letter is a tangible paper or effect held within a government-regulated postal system that protects its confidentiality. Telephone communications, by contrast, were spoken messages transmitted over wires outside the speaker’s premises; the Constitution did not expressly make those conversations protected objects of a search or seizure.
