The Supreme Court on GPS Tracking: U.S. v. Jones

Published for NC Criminal Law on January 24, 2012.

Yesterday, the United States Supreme Court decided United States v. Jones, the important GPS tracking case I previously blogged about here. (The case was captioned United States v. Maynard at that time.) In brief, Washington, DC officers suspected that the defendant was a drug dealer. They wanted to track his movements, so they obtained a search warrant that allowed them to install and monitor a GPS tracking device on a Jeep owned by the defendant’s wife but driven exclusively by the defendant. However, while the warrant authorized installation of the device in DC within 10 days, the officers didn’t complete the installation until the 11th day, in Maryland. They then tracked the defendant for 28 days. Among other things, they determined that he had visited a stash house in which the officers ultimately found large quantities of money and cocaine. Facing drug charges, the defendant moved to suppress the tracking data. Because the officers had failed to comply with the terms of the warrant, the district court treated the officers’ conduct as being warrantless activity. (All subsequent courts followed suit on this point.) Nonetheless, it mostly denied the defendant’s motion, concluding that the defendant had no reasonable expectation of privacy in his travels on the public roads, and therefore, that the officers’ conduct was not a “search” for Fourth Amendment purposes. The government introduced the tracking data at trial and the defendant was ultimately convicted. He appealed. The DC Circuit reversed, holding that prolonged GPS monitoring is a Fourth Amendment search. [...]
