The New Jersey Supreme Court will hear arguments on Tuesday in State v. Earls, an important case regarding the privacy of cell phone location information. At issue is whether real-time location data should be disclosed by a cell phone provider without a warrant or a court order. EPIC Appellate Advocacy Counsel Alan Butler will present oral argument along with counsel for the Defendant and amici ACLU-NJ. In response to the Court's request for supplemental briefing, EPIC's brief outlined the current state of location tracking technology and argued that cell phone users have a reasonable expectation of privacy under both the Federal and State constitutions. For more information, see EPIC: State of NJ v. Earls and EPIC: In re Historical CSLI.
