Supreme Court ruling guts government’s use of geofence warrants
Monday, June 29, 2026
The U.S. Supreme Court has limited the government's ability to use geofence warrants, which allow law enforcement to identify individuals present in a specific geographic area at a specific time based on their phone location data. The Court did not rule that geofence warrants are unconstitutional, but rather established restrictions on how they can be used. The decision addresses Fourth Amendment concerns regarding privacy and unreasonable searches. Legal experts and civil liberties advocates have offered varying interpretations of what the ruling means for future law enforcement practices.
