Techdirt reports that until May 31 the Fourth Circuit Court of Appeals was the only appeals courts to rule warrantless access to cell site location data violated the Fourth Amendment. It was a limited decision, just concerning the collection of historical cell site data for extended periods of time as the court believed the records would give authorities considerable detail about a person's private movements. That changed with a May 31 ruling. "We now hold that the Government’s acquisition of historical [data] from Defendants’ cell phone provider did not violate the Fourth Amendment. Supreme Court precedent mandates this conclusion. For the Court has long held that an individual enjoys no Fourth Amendment protection “in information he voluntarily turns over to [a] third part[y].'," according to the court's opinion.
