Supreme Court Reviews GPS Privacy Issues
On November 8, 2011, the U.S. Supreme Court heard oral arguments in the case of United States v. Antoine Jones (No. 10-1259), which examines the constitutional privacy rights of American citizens in the face of modern tracking systems based on GPS and other technologies.
The case has raised concerns among privacy groups about the warrantless use of GPS to track the movement of citizens for extended periods of time. Conversely, the Department of Justice contends that using GPS to track a vehicle on public roads provides no more information than what police could obtain through visual surveillance.
Issues Under Review
In this case, the Court will decide on two questions:
- Whether the warrantless use of a tracking device on Jones's vehicle to monitor its movements on public streets violated the Fourth Amendment; and
- Whether the government violated Jones's Fourth Amendment rights by attaching the GPS tracking device to his vehicle without a valid warrant and without his consent.
A decision is not expected until 2012.
In September 2005, the FBI and District of Columbia (D.C.) police attached a hidden GPS device to the vehicle of suspected drug dealer Antoine Jones in a public parking lot. The device recorded and transmitted the vehicle's movements for 28 days.
The tracking data showed Jones made frequent visits to a suspected stash house. Jones was ultimately charged with conspiring to distribute narcotics.
Jones filed a motion to exclude the GPS data at trial. The police had obtained a federal warrant to install the tracking device on Jones's vehicle in D.C. within 10 days, but they installed it in Maryland, a day after the warrant expired.
The U.S. District Court for the District of Columbia admitted into evidence the GPS data collected while Jones's car was on public streets, but suppressed data from inside his garage. Jones was convicted of conspiracy to distribute cocaine and is now serving a life sentence.
Jones appealed the partial admission of GPS evidence to the U.S. Court of Appeals for the D.C. Circuit. That court ruled that Jones had a reasonable expectation of privacy in the public movements of his vehicle over the course of a month, that the GPS surveillance constituted a "search" within the meaning of the Fourth Amendment, and that a valid search warrant was required.

The Department of Justice petitioned the Supreme Court to review the case, which was accepted on June 27, 2011.
A number of other federal and state courts across the nation have ruled on the use of GPS-based vehicle surveillance by law enforcement. Some of these rulings are in conflict with the current Jones ruling and with each other. The Supreme Court case should provide clarity on the basic issues and set precedents for future court rulings.
The various rulings to date include:
United States v. Robinson (No. 4:11 CR 361 AGF)
Correction Dec 2011: The U.S. District Court for the Eastern District of Missouri issued a pre-trial recommendation saying that the use of a GPS device to track a suspect's vehicle on public roads was not a "search" and did not violate his Fourth Amendment rights. This case has not yet gone to trial.
