A Federal judge has ruled that to law enforcement officers must have a warrant to access cell phone locational data. Courts are divided regarding whether or not this type of data should be protected by a warrant requirement. Judge Garaufis of the Eastern District of New York, found that "The fiction that the vast majority of the American population consents to warrantless government access to the records of a significant share of their movements by 'choosing' to carry a cell phone must be rejected In light of drastic developments in technology, the Fourth Amendment doctrine must evolve to preserve cell-phone user's reasonable expectation of privacy in cumulative cell-site-location records." EPIC has filed amicus briefs in several related cases. For more information see: EPIC: Commonwealth v. Connolly, EPIC: US v. Jones, and EPIC: Locational Privacy.
