The Central Office of the German Customs Investigation Service investigates crimes under the Foreign Trade and Payments Act and the War Weapons Control Act. To this end, it has the power to restrict the privacy of correspondence, posts and telecommunications. These actions, which encroach on basic rights pursuant to Article 10 of the Basic Law, are scrutinised by the ZFdG Panel in line with Section 23 c (8) of the Customs Investigation Service Act. (The Panel was previously known as the "Panel under Section 41 of the Foreign Trade and Payments Act".)
Acoustic surveillance of the private home was made possible in cases of particularly serious crimes through an amendment of the Basic Law. This severe encroachment on basic rights is scrutinised by Parliament pursuant to Article 13 (6) of the Basic Law.
