Today the Supreme Court of New Jersey held that individuals have a reasonable expectation of privacy in their cell phone location data under the NJ state constitution. In State v. Earls, the New Jersey high court found that "cell-phone location information, which users must provide to receive service, can reveal a great deal of personal information about an individual." This decision is the first to establish a Constitutional right in location data since the U.S. Supreme Court decided United States v. Jones, a GPS tracking case in which several Justices expressed concern about the collection of location data. EPIC participated as amicus curiae in Earls. The New Jersey Supreme Court noted that "EPIC offered helpful details about the current state of cell-phone technology." For more information, see EPIC: State v. Earls and EPIC: Locational Privacy.
