In Chatrie v. United States, the U.S. Supreme Court held that law enforcement access to an individual's Google location history — often gathered through so-called "geofence warrants" — constitutes a search under the Fourth Amendment. The case stemmed from a 2019 bank robbery investigation in Virginia, in which police obtained a broad request for location data on all devices near the crime scene during a set time window, eventually narrowing in on a suspect.
Geofence warrants have become an increasingly common investigative tool, allowing police to request device location data for an entire geographic area over a period of time, rather than targeting a specific individual. Privacy advocates have long argued that this "reverse warrant" approach inverts traditional Fourth Amendment practice, in which probable cause is tied to a known suspect rather than an entire population that happened to be nearby.
The Court's decision signals that this kind of sweeping digital location tracking triggers constitutional search protections, meaning law enforcement will generally need to meet a higher evidentiary bar before compelling technology companies to hand over such data.
Legal analysts expect the ruling to prompt revised guidance for police departments and prosecutors on how geofence and reverse-location requests are drafted, and it may invite further litigation testing the boundaries of digital surveillance under the Fourth Amendment, including requests for cell-site data, IP address logs, and other location-adjacent digital records.
