The federal government appealed Judge Smith's ruling on the grounds that the Fourth Amendment would not apply to cellphone tracking, because "a customer has no privacy interest in business records held by a cell phone provider, as they are not the customer's private papers." Judge Hughes' decision, however, effectively overrules this appeal. "When the government requests records from cellular services, data disclosing the location of the telephone at the time of particular calls may be acquired only by a warrant issued on probable cause," Judge Hughes wrote. "The standard under [today's law] is below that required by the Constitution." The law in question, of course, is the Stored Communications Act -- a law bundled under the Electronic Communications Privacy Act of 1986, which allows investigators to obtain electronic records without a warrant. This month's decision implicitly calls for this law to be reconsidered or revised, though it's certainly not the only ruling to challenge it, and it likely won't be the last, either.
