In re Application of the U.S., No. 08-4227 (3d Cir. Sept. 7, 2010), involves whether the Government can covertly obtain, without a showing of probable cause, historical cellular tower data (also known as cell site location information, or CSLI) from a cellular phone service provider, under the Stored Communications Act, 18 U.S.C. s 2703.
In this case, the Government – without first obtaining a warrant or subpoena or consent of the cell phone subscriber – applied for a court order requiring disclosure of CSLI as authorized under Sec. 2703(c). The Magistrate Judge denied the application, concluding that nothing in the Act authorizes the Magistrate Judge to order a provider’s covert disclosure of CSLI absent a showing of probable cause under Federal Rule of Criminal Procedure 41. The District Court affirmed the Magistrate Judge’s denial.
