Supreme Court Rules on Google Location Data Searches

Police Must Respect Privacy When Seeking Google Location History

The United States Supreme Court has issued a landmark Fourth Amendment decision that significantly strengthens privacy protections for individuals whose cell phone location information is stored by Google. In Chatrie v. United States, the Court held that police conduct a Fourth Amendment search when they obtain a person’s Google Location History through a geofence warrant. The ruling recognizes that individuals have a reasonable expectation of privacy in detailed records showing where they travel and reinforces constitutional protections against broad digital surveillance.

For anyone facing criminal charges based upon Google location evidence, the decision may provide important grounds to challenge the government’s investigation.

What Is a Geofence Warrant?

Unlike a traditional search warrant targeting a specific suspect, a geofence warrant begins with a location. Investigators identify a crime scene and ask Google to provide information about every device located within a designated geographic area during a certain period of time. In Chatrie, police investigating a Virginia bank robbery obtained a warrant requiring Google to disclose information for every Google user whose phone was within approximately 150 meters of the bank during the robbery. Google initially produced anonymous location data for numerous users. Police gradually narrowed the list until Google revealed the identities of three individuals, one of whom became the defendant.

Why the Supreme Court Found a Fourth Amendment Search

The Supreme Court relied heavily on its earlier decision in Carpenter v. United States, which held that historical cell-site location information is protected by the Fourth Amendment. The Court explained that Google’s Location History is even more revealing than traditional cell phone location records because it:

Because this information creates an “intimate window into a person’s life,” the Court concluded that people maintain a reasonable expectation of privacy in those records.

Sharing Information with Google Does Not Eliminate Privacy Rights

The government argued that because users voluntarily enabled Google’s Location History feature, they surrendered any Fourth Amendment protection under the “third-party doctrine.” The Supreme Court rejected that argument. The Court noted that Google frequently encourages users to enable Location History without fully explaining how extensively their movements will be recorded or that the information could later be turned over to law enforcement. The Court concluded that simply using ordinary smartphone features does not amount to voluntarily giving the government unrestricted access to highly personal location data.

Even Short-Term Location Tracking Is Protected

The government also argued that obtaining only two hours of location information should not require Fourth Amendment protection. Again, the Supreme Court disagreed. The Court recognized that even a brief period of location tracking may reveal highly private information, such as visits. The Fourth Amendment protects against unreasonable government intrusion regardless of whether police seek hours or weeks of location information.

The Court Did Not Decide Whether This Particular Warrant Was Valid

Although the Supreme Court ruled that obtaining Google Location History is a Fourth Amendment search, it did not decide whether the geofence warrant used in this case satisfied constitutional requirements. Instead, the Court sent the case back to the Fourth Circuit Court of Appeals to determine whether the warrant met the Fourth Amendment’s requirements of:

Why This Decision Matters in Pennsylvania Criminal Cases

Digital evidence is becoming increasingly common in criminal investigations. Police frequently seek:

Following Chatrie, defense attorneys have another powerful constitutional argument to challenge investigations based on location data. If police obtained Google location information without satisfying Fourth Amendment requirements, that evidence—and any evidence derived from it—may be subject to suppression. Every case involving digital evidence should be carefully reviewed to determine whether investigators complied with constitutional search and seizure protections. It must be noted that this case does NOT hold that the police cannot obtain such information. This case simply requires the police to do their jobs correctly, no short cuts, and obtain a valid search warrant.
