The Obama administration told a federal court Tuesday that the public has no “reasonable expectation of privacy” in cellphone location data, and hence the authorities may obtain documents detailing a person’s movements from wireless carriers without a probable-cause warrant.
The administration, citing a 1976 Supreme Court precedent, said such data, like banking records, are “third-party records,” meaning customers have no right to keep it private. The government made the argument as it prepares for a re-trial of a previously convicted drug dealer whose conviction was reversed in January by the Supreme Court, which found that the government’s use of a GPS tracker on his vehicle was an illegal search.
