Divided Supreme Court backs phone location privacy rights in ‘geofence’ warrant case

MS NOW · · International · Surveillance & Civil Liberties

The U.S. Supreme Court, in a divided ruling, sided with phone location privacy rights in a case involving geofence warrants, which allow law enforcement to collect location data on all devices near a specific place and time.

Why this matters: Geofence warrants work by treating everyone near a crime scene as a potential suspect. Your phone does not know a robbery happened down the street, but if it was there, your data can end up in a government dragnet. A divided court means this protection is real but fragile. The dissent matters. Future cases, different justices, or a narrower fact pattern could chip away at what was won here. For now, your location history has more constitutional cover than it did before.
