The principal inventor of the Global Positioning System is asking the U.S. Supreme Court to renounce the Obama administration’s position that it may affix GPS devices to vehicles and track their every move without a court warrant.
Roger L. Easton, awarded the National Medal of Technology in 2006, joined the Center for Democracy & Technology, the Electronic Frontier Foundation and other academics in a friend-of-the-court brief lodged Monday in one of the biggest Fourth Amendment cases in a decade — one weighing the collision of privacy, technology and the Constitution. The justices are scheduled to argue the case Nov. 8.
Easton, now 90 and the principal inventor and developer of the Timation Satellite Navigation System at the Naval Research Laboratory more than five decades ago, and the others are telling the high court that its precedent on the topic is outdated, and the government’s reliance on it should be rejected.
One of the Obama administration’s main arguments in support of warrantless GPS tracking is the high court’s 1983 decision in United States v. Knotts, in which the justices said it was OK for the government to use beepers known as “bird dogs” to track a suspect’s vehicle without a warrant. Unlike beeper-assisted surveillance, which requires human “visual” surveillance, “GPS tracking is an automated process wholly divorced from human observation,” (.pdf) the amicus brief said.
