The Eleventh Circuit, sitting en banc, has ruled, in U.S. v. Davis, that law enforcement may obtain cell-site location data from mobile carriers without a warrant.  The court affirmed a district court’s ruling that the police had not violated defendant Quartavious Davis’s Fourth Amendment rights by obtaining his cell-site location data from his mobile service provider with an order under Section 2703(d) of the Electronic Communications Privacy Act rather than a search warrant.  The appeals court concluded that Davis did not have a reasonable expectation of privacy in the cell-site location data since that data constituted the business records of the mobile service provider and a reasonable person would know that his phone transmits its rough location to the provider.  A three-judge panel of the Eleventh Circuit had previously reached the opposite conclusion.
