The U.S. Supreme Court ruled six-three that geofence warrants are searches under the Fourth Amendment and are therefore unconstitutional [1].
This decision restricts how law enforcement agencies use digital location data to identify suspects. By classifying these broad requests as searches, the Court ensures that police cannot bypass constitutional protections to sweep up data from every device in a specific area.
Justice Elena Kagan said that the location data collected through these warrants reveals intimate details about a person’s movements [1]. The Court held that this level of surveillance creates a reasonable expectation of privacy that the government may not violate without a warrant that meets specific Fourth Amendment standards [1], [2].
The ruling was announced on June 29, 2026, following a decision reached on June 28 [2]. Geofence warrants typically allow police to request data from companies like Google to identify every user whose device was within a certain geographic boundary during a specific timeframe.
Under the new ruling, the Court determined that the broad nature of these warrants constitutes an unreasonable search [1]. This prevents the government from using a "dragnet" approach to identify individuals based on their proximity to a location, a practice that critics have long argued violates the privacy of innocent bystanders.
The six-three split reflects a divide on the bench regarding the intersection of modern technology and historical privacy rights [1]. Despite this division, the majority opinion establishes a firm precedent that digital footprints are protected from warrantless government seizure [2].
“The U.S. Supreme Court ruled six-three that geofence warrants are searches under the Fourth Amendment.”
This ruling shifts the legal burden back to law enforcement, requiring them to provide specific probable cause for individual suspects rather than using location data to find suspects after the fact. It effectively ends the era of 'reverse-location' searches, where the government identifies people based on where they were, rather than identifying a person and then searching for their location.
