geofence warrant | Fourth Amendment privacy | location data rights

The Supreme Court just ruled on geofence warrants in Chatrie v. United States. Learn what this Fourth Amendment privacy ruling means for your location data rights.

Today, the Supreme Court issued one of the most important digital privacy decisions it has ever handed down. Most people don’t realize how significant this is.

Chatrie v. United States. 6-3. The Fourth Amendment wins. Your location data is yours.

Let me explain what happened and why you should care.

What Happened in Chatrie v. United States

Okello Chatrie was convicted of robbing a credit union in Virginia in 2019. Police didn’t have a suspect. What they had was a tool. They went to a magistrate and obtained what’s called a geofence warrant, directing Google to search the location history of every single device within 150 meters of the bank during the time of the robbery. Not a warrant for a specific person. Not a warrant tied to probable cause about any individual. A warrant to cast a net over everyone in the area and see who turned up. Google returned a list. Chatrie was on it. That led to a search of his home, which led to his conviction.

He moved to suppress the evidence. The district court agreed the warrant violated the Fourth Amendment but let the evidence in anyway under the good-faith exception. The Fourth Circuit affirmed, split 7-7 on whether a search had even occurred. The Supreme Court took the case.

In plain terms: A geofence warrant doesn’t target a specific person. It targets a place and time, then pulls the location data of every phone that passed through, hoping one of them belongs to a suspect. That’s the practice the Supreme Court was asked to evaluate.

How the Court Ruled

Today, Justice Kagan, writing for a majority that included Chief Justice Roberts and Justices Sotomayor, Kavanaugh, Jackson, and Gorsuch, held that yes, obtaining someone’s cell phone location data from Google is a Fourth Amendment search. An individual has a legitimate expectation of privacy in records about where their phone has been. The fact that Google collected and stored that data doesn’t eliminate the constitutional protection. The Court remanded to the Fourth Circuit to decide, for the first time, whether this specific warrant actually satisfied the Fourth Amendment’s requirements of probable cause and particularity.

The dissent, written by Justice Alito and joined by Thomas and Barrett, would have held that Chatrie had no reasonable expectation of privacy in data he voluntarily shared with a third party.

In plain terms: Accessing your phone’s location history now legally counts as a search under the Constitution. That means law enforcement needs a warrant, and that warrant has to be specific to you, not a sweep of everyone in an area.

Why the Majority Got It Right

The dissent’s position isn’t without grounding. The third-party doctrine, the idea that information voluntarily handed to a company forfeits Fourth Amendment protection, has governed this area of law for decades, and applying it here follows a coherent logical thread.

Still, the majority is right, and the reason matters beyond this case.

A geofence warrant is a general warrant. The Founders put the Fourth Amendment in the Constitution specifically because they despised general warrants. The British Crown used them to ransack homes and papers without identifying any person or any crime with specificity. They were instruments of surveillance and control, not targeted law enforcement. A warrant that says “give us the location data of everyone near this location at this time” is that same tool, updated for the digital age. It starts with a place and works backward to identify people. It compels a search of millions of innocent people’s data on the theory that one of them might have done something wrong. That’s not what probable cause means. That’s not what particularity means. And it’s not what the Constitution allows.

Why This Matters for You

The practical stakes here are enormous. Google alone receives thousands of geofence warrants a year. Microsoft, Uber, and Yahoo receive them regularly too. Every person who has ever had their phone’s location tracked, which is nearly everyone in this country, is potentially subject to being swept into a criminal investigation not because they did anything suspicious, but because they happened to be near a place where something later happened. Your doctor’s office. A protest. The technology doesn’t discriminate, and until today, the law largely didn’t either.

In plain terms: If your phone was ever near a location later tied to a police investigation, your location data could have been pulled into that investigation. This ruling raises the bar law enforcement has to clear before that can happen.

What Happens Next for Chatrie

There’s a catch worth noting. The Court’s ruling doesn’t automatically free Chatrie or throw out his conviction. The good-faith exception issue was not before the Court, and it’s been sent back to the Fourth Circuit. Because officers relied on a signed warrant, that exception could still apply and the evidence might still come in. The constitutional victory today is real. Whether it changes outcomes in Chatrie’s specific case is a separate, unresolved question.

But the principle the Court established today is not narrow. Any law enforcement use of location data from tech companies is now a Fourth Amendment search, full stop. That means it requires a warrant. And that warrant has to meet the Constitution’s actual requirements: probable cause tied to a specific person or thing, and particularity describing exactly what is to be searched and seized. A dragnet warrant covering an entire geographic area does not meet that standard. The Fourth Circuit now has to say so explicitly.

In plain terms: Chatrie’s own case isn’t fully resolved yet. But the constitutional rule moving forward is clear: blanket location-data sweeps without individualized suspicion are no longer good enough.

This is how the Fourth Amendment is supposed to work. The government doesn’t get to search first and develop suspicions later. The Court said so today, and that matters for everyone, whether you’ve ever been near a crime scene or not.
