In Foltz v. Virginia, the Virginia Court of Appeals held that law enforcement may place a GPS tracking device on a vehicle without violating the Fourth Amendment. The Court found that the defendant did not have an expectation of privacy, and therefore attaching the tracking device to the bumper did not require a warrant. The court distinguished its ruling from Commonwealth v. Connolly, a recent Massachusetts case, which held that police must obtain a warrant before using GPS devices to monitor vehicles. The Virginia court explained that Connolly was unpersuasive because the Virginia Constitution is co-extensive with the federal Fourth Amendment while the Massachusetts Constitution is more expansive. EPIC filed an amicus brief in Connolly, urging the court to adopt a warrant requirement. For more information, see EPIC: Commonwealth v Connolly.
