Passage: Amending the UN Charter, possibly through a Charter Review Conference under Article 109 of the UN Charter, is a commonly cited possibility. This is difficult because it requires ratification by two-thirds of UN members, including all five permanent members of the Security Council. There have been only five amendments to the UN Charter since 1945, and none of them were done through the Article 109 process. Louis Sohn and Grenville Clark, in their 1958 book World Peace Through World Law, proposed establishing a UN Parliamentary Assembly through this method.Another possibility is establishing the UNPA as a subsidiary body of the UN General Assembly. The General Assembly has authority to do this under Article 22 of the UN Charter. Erskine Childers and Sir Brian Urquhart endorsed this approach in their 1994 book, Renewing the United Nations System. The Committee for a Democratic UN also recommended the establishment of UNPA by Article 22 or by transformation of the Inter-Parliamentary Union in its report, Developing International Democracy, authored by Andreas Bummel, co-founder and director of the UNPA campaign. In 2006, the Council of Europe passed a resolution noting, "A decisive step towards the development of a UN parliamentary dimension could be the establishment of an experimental parliamentary committee with consultative functions for General Assembly committees."Yet another option is to create the UNPA as a nongovernmental organization of democratically elected legislators. This would have the advantage of not requiring the cooperation of (sometimes dictatorial) national governments or world parliamentary organizations with dictatorial members, so only democratic legislators, parliaments and countries would be represented. The World Constitution and Parliament Association and other NGOs have attempted to set up workable parliaments. Dieter Heinrich critiqued this approach by saying, "If it did succeed on any scale, it would divert resources from pressuring governments on thousands of specific issues,...
