US Supreme Court: Geofence Warrants Need Constitutional Privacy Protections
Original: US Supreme Court rules geofence warrants require constitutional protections
Why This Matters
Establishes Fourth Amendment protections for digital location data; affects widespread law enforcement surveillance practices nationwide.
The US Supreme Court ruled 6-3 that law enforcement's use of geofence warrants—which collect smartphone location data from people near crime scenes—requires Fourth Amendment privacy protections. Justice Elena Kagan wrote that individuals have a reasonable expectation of privacy in cell phone location records.
The US Supreme Court has ruled that geofence warrants, which allow law enforcement to compel tech companies to provide sensitive cell phone location data from individuals within a virtual boundary during a specific timeframe, constitute a Fourth Amendment search requiring constitutional privacy protections. Justice Elena Kagan wrote the majority opinion in the 6-3 decision in Chatrie v US, stating: "An individual has a reasonable expectation of privacy in records about his cell phone's location, and police intrude on that constitutionally protected interest when they demand the information – even though for only a limited time, and from a third-party tech company." The ruling addresses widespread law enforcement use of geofence warrants, which give police and FBI agencies power to collect location data from individuals at or near crime scenes without restricting requests to precise targets. The case originated from Richmond, Virginia police tracking armed bank robber Okello Chatrie, who fled with $195,000. Chatrie had opted into Google's optional "location history" feature. He was eventually sentenced to 12 years in prison after pleading guilty. The decision marks a significant test of how privacy rights apply in the digital era.
