also draw on some of NATO's assets in its own peacekeeping operations. Originally, under the Amsterdam Treaty, the WEU was given an integral role in giving the EU an independent defence capability, playing a major role in the Petersberg tasks; however that situation is changing. On 13 November 2000, WEU Ministers met in Marseille and agreed to begin transferring the organisation's capabilities and functions to the European Union, under its developing Common Foreign and Security Policy (CFSP) and Common Security and Defence Policy (CSDP). For example, on 1 January 2002, the WEU's Security Studies Institute and the Satellite Centre were transferred to the EU and became the European Union Institute for Security Studies and the European Union Satellite Centre. Notably, the role given to the WEU in the Amsterdam Treaty, was removed by the Nice Treaty. The Treaty of Lisbon has provisions for cooperation between the EU and both NATO (including the Berlin Plus agreement) and the WEU. However the defence commitment, of Article 4 of the Brussels Treaty, has not been subsumed. Article 42(7) of the Treaty of the European Union, as amended by the Treaty of Lisbon, could be viewed as incorporating that defence commitment into the EU framework. The European Union Institute for Security Studies (EUISS) and European Union Satellite Centre (EUSC), both established to function under the EU's CFSP pillar, were both replacements to the Western European Union Institute for Security Studies and the Western Union Satellite Centre which had been established to function in connection to the WEU. With the transfer of responsibilities, the WEU's Parliamentary assembly was urged to dissolve itself, as it had a mandate to supervise WEU politics, not the EU's CSDP politics. But the Assembly saw itself as playing an important role, particularly with greater right of scrutiny, membership, experience and expertise in defence policy. Therefore, it renamed itself the "Interim European Security and Defence Assembly" and urged the European Convention to include it as a second chamber within the EU's institutional framework. Hence it argued it could effectively scrutinise the CSDP, help improve EU-NATO relations and be more suited, being composed of national parliamentarians, to the intergovernmental style of the CSDP. However, with the European Constitution aiming to streamline and simplify the EU's foreign policy, for example combining the two main foreign policy posts, it was not seen as wise to then create a separate double legislature for the CFSP,
