Commonwealth v. Augustine

EFF filed an amicus brief with the Massachusetts Supreme Judicial Court, asking it to rule police must get a search warrant in order to access historical cell site information. We argued that as cell phones and especially smartphones become prevalent, and the number of cell towers and cell sites increases, the location information revealed by cell sites becomes more precise. Since location information provides details on a person's movements, associations and affiliations, we argue that it must be protected by a search warrant requirement.

Commonwealth v. Rousseau

EFF urged the high court of Massachusetts to protect the rights of passengers in cars that law enforcement are tracking with GPS surveillance technology, arguing that both the driver and the passenger of a car have legal standing to challenge the collection of sensitive location data gathered by the GPS devices.
