The Government believe that domestic legislation and international legal instruments already exist to deal satisfactorily with the concerns raised by the Secretary-General of the Council of Europe. The activities of the British security and intelligence agencies are governed by domestic legislation. Civil and state aircraft and state immunity are governed by customary international law and by treaties, including the Chicago Convention and the 2004 UN Convention on the Jurisdictional Immunities of States and their Property. We see no need to create new mechanisms.
