The U.S. Supreme Court on Monday heard oral arguments in Chatrie v. United States, a high-stakes case that could reshape Fourth Amendment protections in the digital age and determine the future of controversial “geofence” search warrants used by law enforcement.
Geofence warrants allow police and federal agents to compel companies like Google to disclose location data for all users present in a designated geographic area during a specific time window. Investigators use the tool to identify potential suspects by sifting through vast troves of smartphone location information, effectively searching first and developing probable cause later.
Civil liberties groups argue the practice is inherently overbroad and violates constitutional safeguards against unreasonable searches. Critics point to instances where innocent bystanders, protest attendees, and unrelated individuals have had their data swept up, sometimes due to warrants that extended far beyond the crime scene, reported Tech Crunch.
The case stems from the 2019 armed robbery of a bank in Virginia. Surveillance footage showed a suspect using a cellphone. Police obtained a geofence warrant from Google, requesting anonymized location data for devices within a small radius of the bank around the time of the crime. Google initially provided data for multiple accounts. Investigators then sought identifying information for a subset of users, including Okello Chatrie, who was later linked to the scene, arrested, and sentenced to more than 11 years in prison after pleading guilty.
Chatrie’s legal team challenged the warrant, contending it lacked sufficient probable cause tying him—or any specific account—to the robbery. Lower courts split on the issue, with one ruling the warrant failed to meet constitutional standards but ultimately allowing the evidence under the “good faith” exception. Chatrie’s appeal argues the warrant unconstitutionally permitted a broad search of hundreds of millions of Google users’ data.
