The U.S. Court of Appeals for the Eleventh Circuit has vacated its ruling in U.S. vs. Davis that the government needs a warrant to obtain cell-site location data from a cell service provider and will rehear the case en banc.  As we previously reported, an Eleventh Circuit panel in June held that cell-phone users have a reasonable expectation of privacy in their cell-site location data, despite the fact that the data was conveyed to a third party ‒ the cell service provider ‒ and that police therefore needed a warrant.  The fact that the Eleventh Circuit has decided to rehear this case en bancsuggests that a majority of the full court may not be ready to go this far without further guidance by the Supreme Court, given the continued viability of the "third-party" doctrine.
