“In a reversal of a decision from last year, the Court of Appeals for the Eleventh Circuit ruled today that the government does not need a warrant to search wireless carriers’ cellphone records. Instead, the court ruled, the government must only meet the standard for records obtainable under the Stored Communications Act, which requires that the government ‘offers specific and articulable facts showing that there are reasonable grounds to believe’ the records ‘are relevant and material to an ongoing criminal investigation.’ The court ruled that there was no reasonable expectation of privacy toward the records and that the records were not obtained by what constitutes a ‘search’.”
