"The Assembly invites member States to take all necessary measures to ensure compliance with obligations under the General Agreement on Privileges and Immunities of the Council of Europe and its Protocol, on which they have not expressed reservation or made an interpretative declaration. It is concerned about the changes to national systems of parliamentary immunity, in particular by means of amending or suspending constitutional provisions, which lead, in practice, to render ineffective Article 15.a of the General Agreement on Privileges and Immunities, and to remove de facto protection accorded to members of the Assembly on the territory of their own State, as defined by the Assembly in its Resolution 1490 (2006)."
