A US judge has temporarily stopped the National Security Agency (NSA) from destroying phone metadata it collected, thanks to an intervention by the Electronic Frontier Foundation (EFF). The privacy watchdog argued that the documents were key to upcoming lawsuits stemming from mass surveillance revelations revealed by Edward Snowden. Ironically, the spy agency itself wants to preserve the records for security reasons, but a foreign surveillance court ordered them destroyed. The reason? Such records would actually violate the rights of persons in the phone lists. However, the EFF claimed that court wasn't aware of existing orders to keep the documents, which stemmed from a suit it filed in July and another from 2008. A hearing is now scheduled for March 19th to determine once and for all if the phone records will be destroyed or kept -- with your privacy being argued in both cases.
