In a recent decision, the Supreme Court determined that cellphone users' location history is protected under constitutional privacy provisions. This ruling came about in the case of a bank robber who was identified through the use of a geofence warrant. The court's decision was written by Justice Elena Kagan, with a majority of 6-3.

According to the ruling, individuals do not give up their expectations of privacy when it comes to their cellphone location information. Further details on this decision can be found through KSAT 12, the ABC affiliate in San Antonio, TX.
