Clinton v. Virginia
Headline: Court reverses and limits police use of 'spiked' microphones that penetrate private property, ruling such physical intrusion counts as a trespass and curtailing secret audio evidence gathered in homes.
Holding: The Court reversed the lower judgment, holding that police placement of a 'spiked' microphone which physically penetrated a person's premises amounted to an actual trespass and undermined the use of that evidence.
- Limits police use of hidden microphones that physically penetrate private property.
- Makes audio evidence from such physical intrusions less likely to be admissible.
- Protects homeowners’ privacy against physical intrusion by law enforcement devices.
Summary
Background
A private individual challenged evidence gathered after police used a concealed "spiked" microphone that penetrated the individual’s premises. The case reached the Supreme Court from Virginia’s highest court. The lower-court judgment was reviewed because the legality of the microphone’s placement and its use in the case were disputed.
Reasoning
The central question was whether inserting a microphone that physically entered someone’s property counts as an actual trespass. The Court, in a short per curiam decision, reversed the judgment below and cited earlier decisions (Silverman v. United States and Ker v. California). Justice Clark wrote separately to say he joined the judgment because the device’s penetration amounted to a trespass. The decision therefore treats the police intrusion by the spiked microphone as unlawful physical entry for purposes discussed in the cited precedents.
Real world impact
The decision favors people whose homes or private spaces are physically penetrated by law enforcement devices. It limits the straightforward use of audio gathered by a device that was physically pushed into private property and signals that such evidence may be excluded when it rests on a trespass. As a Supreme Court reversal, the ruling affects how courts and police evaluate similar intrusions in future cases.
Dissents or concurrances
Justice Clark explicitly concurred because he agreed the microphone’s penetration was an actual trespass; Justice White dissented, but the opinion text does not state his reasons.
