The legal basis for the National Security Agency’s collection of telephone "metadata" pursuant to Section 215 of the USA PATRIOT Act has come under widespread criticism since the leaks by Edward Snowden. The Foreign Intelligence Surveillance Court has now released an opinion that explains its rationale for approving that program. The opinion states that the program does not violate the Fourth Amendment because phone customers willingly disclose their non-content phone records to third parties (the telephone companies). The court also concludes that the collection complies with the language of section 215, as further demonstrated by Congress’ reauthorization of that provision. The rationale pretty much tracks what the Obama Administration has said in defense of the program. Only time will tell whether this explanation will satisfy Congress when it comes time to reauthorize section 215 again.
