Since the right to confidentiality of communications is a fundamental right recognised by the Charter, legally binding upon the EU and the Member States, any interference with it, must be limited to what is strictly necessary and proportionate in a democratic society.
Ker je pravica do zaupnosti komunikacij temeljna pravica, priznana v Listini EU o temeljnih pravicah, ki je pravno zavezujoča za EU in države članice, mora biti vsako poseganje vanjo omejeno na to, kar je nujno potrebno in sorazmerno v demokratični družbi.
