9/21/2009Massachusetts Supreme Court Strikes Down Warrantless GPS Spying
Massachusetts Supreme Court ruling insists that police obtain a warrant before using GPS devices to spy on motorists.
The Supreme Judicial Court of Massachusetts ruled last Thursday that police officers need to obtain a warrant before using a Global Positioning Satellite (GPS) device to track a motorist. The ruling was handed down in the case of Everett H. Connolly who was convicted of cocaine trafficking after police traced his activities using a GPS device five years ago.
For more than a year, police suspected that Connolly was a drug dealer and used traditional surveillance and investigative techniques to gather evidence. On August 30, 2004, state police took the next step by obtaining a warrant to place a GPS tracker on Connolly's minivan. Using data from the device, police believed Connolly was on his way back from a drug buy in New York. On September 9, officers armed with a new search warrant arrested Connolly in Cape Cod. A search uncovered 124 grams of cocaine hidden in the vehicle.
In his defense, Connolly attempted to use technicalities to argue that the warrant for installing the GPS tracking device had expired, but state prosecutors went further and implied that no such warrant was even required. This spurred the high court to make clear its position that a valid warrant is always necessary.
"We conclude that the installation and use of the GPS device in the circumstances of this case was a seizure requiring a warrant, and that the warrant obtained had not expired when the minivan was seized," Justice Judith A. Cowin wrote for the majority. "We conclude that a warrant was required here because the initial installation of the particular device clearly constituted a seizure under article 14 [of the Massachusetts Declaration of Rights]... It is a seizure not by virtue of the technology employed, but because the police use private property (the vehicle) to obtain information for their own purposes."
The court found in this case that the police followed all proper procedures to obtain judicial permission before acting. Given this, the full court upheld Connolly's conviction. Three judges, however, disagreed with the majority's reasoning that the use of GPS constitutes a 'seizure' of property.
"When there is no physical intrusion into the vehicle to install the GPS device but simply the attachment of a battery-powered device to the exterior of the vehicle, the police have not seized the vehicle, but instead have invaded the reasonable expectation of privacy of any person authorized to drive that vehicle," Justice Ralph D. Gants wrote in his dissent. "Our constitutional analysis should focus on the privacy interest at risk from contemporaneous GPS monitoring, not simply the property interest. Only then will we be able to establish a constitutional jurisprudence that can adapt to changes in the technology of real-time monitoring, and that can better balance the legitimate needs of law enforcement with the legitimate privacy concerns of our citizens."
In May, the New York State Court of Appeals agreed with the privacy reasoning of the dissenting justices, while Wisconsin's second-highest court found no problem with warrantless spying.
