Cellphone tower

A federal appeals court in Atlanta is considering whether investigators must obtain a search warrant to obtain cellphone tower tracking data.

A three-judge panel of the 11th U.S. Circuit Court of Appeals in June ruled investigators must get a search warrant to get the data, which is widely used to show suspects were in the vicinity of a crime.

The federal government asked to have the decision reconsidered by the full court and oral arguments were held Tuesday.

The issue arises from a Miami case in which federal prosecutors used a court order to get cellphone tower data over a 67-day period for Quartavious Davis, a suspect in a string of robberies.

Attorneys for Davis argue his constitutional rights were violated, when law enforcement obtained that data without a warrant.

Similar cases are winding their way through the legal system, and the Supreme Court could make a final decision on the issue.
