Supreme Court Rules Warrants Needed for Google Location Data Access
The Supreme Court ruled that warrants are required to access cellphone location data.
Why it matters: This landmark decision strengthens digital privacy rights and reshapes how law enforcement can use geofence warrants. Legal teams handling digital evidence and privacy issues must revise their practices and policies accordingly.
- On June 29, 2026, the Supreme Court decided 6-3 that police must get warrants to obtain cellphone location data.
- The ruling arose from Chatrie v. United States, involving a 2019 Virginia bank robbery identified via a 150-meter geofence and 30-minute timeframe.
- Justice Elena Kagan wrote that users retain privacy rights despite consenting to services like Google’s location tracking.
- The Court remanded for lower courts to evaluate if warrants meet Fourth Amendment standards of particularity and probable cause.
On June 29, 2026, the U.S. Supreme Court delivered a pivotal 6-3 ruling in Chatrie v. United States, establishing that law enforcement must obtain warran ts before accessing individuals' cellphone location data. This decision significantly expands privacy protections for smartphone users.
The case involved Okello Chatrie, linked to a 2019 bank robbery in Virginia through the use of a 'geofence warrant.' Police identified phones located within a 150-meter radius near the crime scene during a 30-minute period. The Supreme Court emphasized in its ruling that individuals do not lose their expectation of privacy merely by using common location-based services like Google’s tracking.
Justice Elena Kagan, authoring the majority opinion, stated, "A cellphone user is not to be viewed as sharing private information with third parties—which then can be freely passed on to the government—just by doing the ordinary things cellphone users do." This marks a reinforcement of privacy rights in the digital age.
The Court vacated the Fourth Circuit's ruling and sent the case back for further review to determine whether the geofence warrant in question met the Fourth Amendment's rigorous demands for particularity and probable cause at every stage of the search process.
This ruling builds on the 2018 Carpenter v. United States decision, which first required warrants for historic cell-site location information, and extends those protections to the increasingly used geofence warrants that gather location data from multiple devices within defined areas and times.
Georgetown law professor Paul Ohm noted, "The court reaffirmed that the police need a search warrant to turn private services like Google’s location tracking into a state surveillance tool." This ruling impacts law enforcement's data collection methods and underscores courts' adaptation to evolving digital technologies.
By the numbers:
- 6-3 — Supreme Court decision margin
- 150 meters — geofence radius used to identify devices near crime
- 30 minutes — time frame considered during geofence warrant execution
Yes, but: Lower courts must still determine how strictly to apply requirements for particularity and probable cause when issuing geofence warrants, which could lead to varied interpretations.
What's next: The case returns to the lower courts to review whether the warrant in Chatrie met constitutional standards, setting a framework for future digital privacy litigation and law enforcement practices.
