The U.S. Supreme Court held unanimously today that police must obtain a warrant before placing a GPS tracking device on a suspect’s car.
The ruling in U.S. v. Jones invalidates the life sentence of Antoine Jones, who was convicted of conspiracy to sell cocaine using evidence obtained over the course of a month from a GPS device attached to Jones’ Jeep Grand Cherokee.
The justices split on the rationale, with a five-justice majority led by Antonin Scalia holding that the attachment of the GPS device to the car was a physical intrusion requiring a warrant under the Fourth Amendment.
“That ruling avoided many difficult questions, including how to treat information gathered from devices installed by the manufacturer and how to treat information held by third parties like cellphone companies,” explains The New York Times’ Adam Liptak.
The four-justice minority, led by Samuel Alito, said that the prolonged time period of the surveillance – a month long – amounted to a search and called the majority’s narrow holding “unwise.”
Justice Sonia Sotomayor, who adopted the majority’s rationale, also wrote her own concurring opinion, in which she asserts that event non-physical intrusions might constitute warrantless searches, before concluding that the court need not answer those questions in this case.
“She makes it clear that she sides with those that see a problem with electronic surveillance too,” writes Marcy Wheeler for emptywheel.
Wheeler continues:

In the meantime we’ve learned the numbing lesson that what Justice Harry Blackmun wrote was not close to the final declaration of women’s reproductive liberty. It was not the beginning of the public’s embrace of educating our young to enable them to make responsible and informed decisions regarding sex and reproductive health. And it was certainly not an opening to the broad cast of reproductive options.
