Supreme Court: Geofence Warrants Are Constitutional Searches Under Fourth Amendment

The Supreme Court ruled geofence warrants constitute Fourth Amendment searches.

On June 29, 2026, the U.S. Supreme Court issued a landmark ruling in Chatrie v. United States, holding that the use of geofence warrants constitutes a search under the Fourth Amendment. This case involved Okello Chatrie, convicted of a 2019 armed robbery in Virginia based on evidence obtained through a geofence warrant.

The Court’s 6-3 decision vacated the lower court’s ruling against Chatrie and remanded the case for further proceedings, emphasizing that law enforcement’s practice of obtaining location data from all devices within a virtual geographic fence—termed geofencing—requires constitutional scrutiny.

Justice Elena Kagan, writing the majority opinion, explained that geofencing involves "drawing a virtual fence around a geographic area where a crime was committed" and then seeking a warrant compelling tech companies to provide location data for any users located within that zone during the relevant timeframe. Such broad collection of location information was determined to constitute a search, thus implicating Fourth Amendment protections against unreasonable searches.

This ruling marks a critical moment in privacy law and digital surveillance, signaling that courts must carefully examine geofence warrants for their reasonableness under constitutional standards. For legal professionals crafting or challenging law enforcement requests, it underscores the evolving boundaries of digital evidence collection.
