Supreme Court to Decide Constitutionality of Warrantless GPS Monitoring

Wired.com's Threat Level blog:

At the Obama administration’s urging, the Supreme Court agreed Monday to review whether the government, without a court warrant, may affix GPS devices on suspects’ vehicles to track their every move.

The Justice Department told the justices that “a person has no reasonable expectation of privacy in his movements from one place to another,” (.pdf) and demanded the justices undo a lower court decision that reversed the conviction and life sentence of a cocaine dealer whose vehicle was tracked via GPS for a month without a court warrant.

The petition, which will not be decided until the new term begins in October, is arguably one of the biggest Fourth Amendment case in a decade — one weighing the collision of privacy, technology and the Constitution.
