Update on GPS Tracking and Privacy Case at Supreme Court
Monday, January 23rd, 2012The US Supreme Court has ruled in the case of United States v. Jones. In Jones, the police, without a valid warrant, placed a global positioning satellite (GPS) technology device on the car of a suspected drug dealer in Washington, D.C. The police then tracked the movements of Antoine Jones for several weeks with this device, and they used the data collected to convict him of conspiracy to sell cocaine. The Supreme Court was set to decide whether the warrantless surveillance and tracking was a search under the Fourth Amendment right against unreasonable searches and seizures. In a unanimous decision (Supreme Court pdf; archive pdf), the court held that police do need a valid warrant to place a GPS device on a vehicle. There were three opinions: the majority by Justice Scalia, a concurrence by Justice Alito and a concurrence by Justice Sotomayor.
The majority opinion was premised on the fact that there was a physical trespass, or intrusion, by putting the device on the vehicle. It did not decide an issue of privacy. Scalia’s majority opinion said, that “It may be that achieving the same result through electronic means, without an accompanying trespass, is an unconstitutional invasion of privacy, but the present case does not require us to answer that question.”
Justice Alito’s concurrence (which included Justices Ginsburg, Breyer and Kagan) accused the majority of “decide[ing] this case based on 18th-century tort law” though “This case requires us to apply the Fourth Amendment’s prohibition of unreasonable searches and seizures to a 21st-century surveillance technique, the use of a Global Positioning System (GPS) device to monitor a vehicle’s movements for an extended period of time.” Read more »
