Supreme Court Weighs Constitutionality of Geofence Warrants

The Case Before the Court
On April 27, 2026 the Supreme Court heard arguments in *Chatrie v. United States*, a challenge to a “geofence” warrant used after a 2019 bank robbery in Midlothian, Virginia. Police obtained Google’s location-history data for every device within a three-football-field area around the robbery, identified 19 users, narrowed the list to three, and arrested Okello Chatrie. The Court must decide whether such warrants violate the Fourth Amendment’s ban on unreasonable searches.
Legal Background and Prior Precedents
The Fourth Amendment protects against “general warrants” that allow searches without specific suspicion. In *Carpenter v. United States* (2018), the Court required a warrant for cell-tower data. Supreme Court litigator Michael Dreeben notes the Court has “grappled…with advancing technology that shrinks the area of privacy the Fourth Amendment was intended to protect” since the early 20th century.
Key Players and Arguments
- Department of Justice (U.S. Solicitor General D. John Sauer) argues that users who enable location history “took no steps to protect” their data, thereby forfeiting a reasonable expectation of privacy.
- Google filed a neutral brief urging the Court to treat location-history records as “digital documents…deserving the Fourth Amendment’s protection.”
- Defense (Attorney Adam Unikowsky) contends the warrant is a modern general search, likening it to “searching every single person’s house.”
- Legal scholars Michael Dreeben and Orin Kerr provide expert testimony on privacy interests.
- Privacy groups – the Electronic Frontier Foundation and the ACLU – filed amicus briefs warning of drag-net surveillance.
Data and Statistics on Geofence Warrants
- Approximately 500 million Google users had opted into location history in 2019.
- Hofstra Law Review reports 11 500 geofence warrants were served on Google in 2020.
- The Midlothian warrant covered an area roughly the size of three football fields and recorded locations every two minutes within a three-meter radius.
- Google initially flagged 19 users, later reduced to three after negotiation.
Criticism and Privacy Concerns
Critics stress that innocent individuals are “swept up” in such searches. Dreeben observes, “They may have been going to church…seeing a psychiatrist…visiting a lover.” The EFF and ACLU argue the Fourth Amendment “requires individualized suspicion,” warning that the government could “draw a geofence around a church, a political rally, or a gun shop” and compel a blanket data sweep.
Official Positions Summarized
- DOJ: Voluntary participation in location services nullifies privacy expectations; the warrant targets Google’s servers, not individuals.
- Google: Location data stored remotely should receive the same Fourth Amendment safeguards as physical records.
- Defense: The warrant functions as a drag-net, violating the amendment’s protection against unreasonable searches.
Conflicting Reports & Gaps
The exact number of geofence warrants issued nationwide remains unknown, and courts are split on whether stored location data constitutes a “search” under the Fourth Amendment.

Implications and Next Steps
The Court’s decision, expected by June 2026, will shape the balance between law-enforcement tools and digital privacy. A ruling upholding geofence warrants could legitimize broad data sweeps, while a reversal may require individualized warrants for location data, influencing future investigations and the handling of cloud-based personal information.
