Supreme Court Rules Constitutional Privacy Protections Apply to Cellphone Users’ Location History

The Supreme Court ruled 6-3 that constitutional privacy protections extend to cellphone location data, even when users voluntarily opt into services like Google's location history. Justice Kagan wrote that people shouldn't be viewed as giving up privacy rights "just by doing the ordinary things cellphone users do." The case involved a bank robber identified through a geofence warrant that captured location data from all phones near the crime scene, with the court sending it back to lower courts to determine if that specific search violated Fourth Amendment protections against unreasonable searches.
