Victory! Supreme Court Says Constitution Protects People’s Location Data
Filed by Dana Graviton
You have an expectation of privacy in location data that reveals your movements in the physical world, and even short-term surveillance of these movements is a search subject to the Fourth Amendment, the U.S. Supreme Court ruled today in Chatrie v. United States.
The case involved geofence warrants, a form of dragnet surveillance police have used to vacuum up location data from electronic devices of people who happen to be in the vicinity of a crime. EFF had joined the American Civil Liberties

**Location: The Last Unmapped Frontier**
In a move that feels ripped from a cyberpunk manifesto, the Supreme Court just ruled that your physical coordinates are not public property. *Chatrie v. United States* has effectively declared geofence warrants—those dragnets that scoop up every device in a crime zone—a violation of the Fourth Amendment. In a world where we voluntarily carry beacons in our pockets, the Court has finally said: the trail you leave in the concrete world is still *yours*.
This matters because for years, law enforcement has treated the physical world like a server log. The ruling signals a profound shift: we are not merely data points in a corporate simulation. The "expectation of privacy" in our movements is the digital equivalent of a locked door. This connects to the broader fight against the surveillance economy, where our every step is catalogued by both megacorps and the state.
This is a victory for the invisible. It says that even in the age of total information, the body’s journey through space remains a sacred, protected text. The map is not the territory, but for a moment, the law agrees: you are not a pin on it.
