The U.S. Court of Appeals for the Second Circuit held, in ACLU v. Clapper, that Section 215 of the USA PATRIOT Act does not authorize the National Security Agency’s bulk telephony metadata collection program. Because it ruled that the program as it is currently operated is not authorized by the statute, the court declined to address the constitutionality of the program. The court’s decision would seem to make it much less likely that Congress will reauthorize Section 215 in its current form before that provision sunsets on June 1. Proponents of the USA Freedom Act, which would place limits on the program, would seem to have the upper hand now, especially in light of new endorsements of that bill from the Obama Administration and the tech industry. But it’s still possible that those still arguing against any changes at all, combined with those arguing for even greater restrictions, will prevent any amendments from making it through Congress prior to June 1.
