Supreme Court restricts use of geofence warrants
Monday, June 29, 2026
The Supreme Court ruled that geofence warrants violate the Fourth Amendment's prohibition against unreasonable searches. Geofencing is a law enforcement technique that uses location data to identify individuals within a specific geographic area. Justice Elena Kagan wrote the majority opinion in the 6-3 decision. The ruling places limits on how police can use this method to gather evidence in criminal investigations.
