Is there experience that can be used for a Parliamentary Assembly at the UN?

Parliamentary assemblies exist in numerous multilateral intergovernmental organizations, for example at the Council of Europe, the Organization for Security and Cooperation in Europe, NATO, the African Union and in Mercosur, among others. In addition, it is possible to draw important lessons from the development of the European Parliament, created as a consultative assembly in 1952 and evolving over decades to today’s legislature directly representing almost 400 million eligible voters.
