Gesetz zur Beschränkung des Brief-, Post- und Fernmeldegeheimnisses
The Act on Restrictions on the Secrecy of Mail, Post and Telecommunications, Gesetz zur Beschränkung des Brief-, Post- und Fernmeldegeheimnisses in German, also known as the G-10 Act, is a German federal law that regulates the surveillance powers of Germany's intelligence agencies. The shortened and more commonly used name, ‘G-10’, refers to Article 10 of the German Basic Law, which enshrines the right to privacy of communication: It is from these provisions that the law seeks to derogate.
