European justice opposed Tuesday to States ordering telecom operators the "generalized and undifferentiated" collection of connection and location data of their users, except for a limited period or in a targeted manner, particularly in the event of a "threat serious for national security ".

Requested by the courts in France, Belgium and the United Kingdom, the Court of Justice of the EU (CJEU) confirmed that "EU law opposes national regulations requiring access providers" to transmit or the generalized and undifferentiated preservation "of metadata of internet connections and telephone conversations for judicial or intelligence purposes. However, it allows framed exemptions in the event of" serious threat to national security "or" the fight against serious crime ", under the supervision of a judge or an independent administrative authority.
