Supreme Court rules on geofence warrants, data privacy case

The Supreme Court ruled 6-3 that police must obtain a warrant to access stored cellphone location data from companies like Google under the Fourth Amendment. The decision in Chatrie v. United States addressed geofence warrants, which require companies to provide location history for devices in a specific area during a time frame. The court sent the case back to a lower court to determine if the warrant used in the case met Fourth Amendment standards.
