  • 754 F.3d 1205 (2014) UNITED STATES of America, Plaintiff-Appellee, v. Quartavious DAVIS, Defendant-Appellant. No. 12-12928. United States Court of Appeals, Eleventh Circuit. June 11, 2014.
  • The prosecution also offered records obtained from cell phone service providers evidencing that Davis and his co-defendants had placed and received cell phone calls in close proximity to the locations of each of the charged robberies around the 1210*1210 time that the robberies were committed, except for the Mayor's Jewelry store robbery. Davis preserved his objection to the cell phone location evidence and his claim that the government's obtaining such evidence without a warrant issued upon a showing of probable cause violated his rights under the Fourth Amendment.
  • The evidence obtained under the order and presented against Davis in the district court consisted of so-called "cell site location information." That location information 1211*1211 includes a record of calls made by the providers' customer, in this case Davis, and reveals which cell tower carried the call to or from the customer. The cell tower in use will normally be the cell tower closest to the customer. The cell site location information will also reflect the direction of the user from the tower. It is therefore possible to extrapolate the location of the cell phone user at the time and date reflected in the call record.

  • Davis's Fourth Amendment argument raises issues of first impression in this circuit, and not definitively decided elsewhere in the country. The evidence at issue consists of records obtained from cell phone service providers pursuant to the Stored Communications Act ("SCA"), 18 U.S.C. §§ 2703(c) and (d). Under that Act, the government can obtain from providers of electronic communication service records of subscriber services when the government has obtained either a warrant, § 2703(c)(A), or, as occurred in this case, a court order under subsection (d), see § 2703(c)(B). The order under subsection (d) does not require the government to show probable cause.
  • As we suggested above, the question whether cell site location information is protected by the Fourth Amendment guarantees against warrantless searches has never been determined by this court or the Supreme Court. Two circuits have considered the question, but not in the context of the use of the evidence in a criminal proceeding. Also, one of those opinions issued before the Supreme Court's decision in United States v. Jones, ___ U.S. ___, 132 S.Ct. 945, 181 L.Ed.2d 911 (2012), the most relevant Supreme Court precedent.
  • In short, we hold that cell site location information is within the subscriber's reasonable expectation of privacy. The obtaining of that data without a warrant is a Fourth Amendment violation.

    11th U.S. Circuit Court of Appeals (Southeastern U.S.) holds that section 2703(d) of the Stored Communications Act, which purports to allow the obtaining of a search warrant without a showing of probable cause, violates the 4th Amendment warrant requirement as applied to cell tower "site location information." That should also apply to "fake" cell towers, like the Stingray device (IMSI catcher) used to obtain the same type of information. Likely doubly so because such devices trespass on a radio connection assigned by the FCC between the legitimate cell tower and the user's telephone.
