A U.S. Court of Appeals has given authorities clearance to track historical location data on cellphones by obtaining a court order rather than a more difficult search warrant. In overruling a lower court decision, the New Orleans-based court ruled that such searches do not violate the Fourth Amendment because they are "clearly a business record." The decision, which is not expected to reach the Supreme Court, could spark a wave of state and federal legislation aimed at limiting such searches.
