To request the General Assembly of the UN to convene a General Conference of Members for the purpose of Reviewing the Charter (1st paragraph of art. 109). 2. Once the Conference is installed anywhere in the world and without a time limit, it is possible to adopt a resolution in the Conference to initiate a legal and political process aimed at transforming the UN into a United Nations Parliament, with the same foundation of the San Francisco Conference of 1945 (derived from the doctrine of ius cogens) "We the Peoples of the United Nations", which expresses the preamble of the Charter. In other words, instead of proposing "any reform" (2nd paragraph of art. 109), the transformation of the entity itself is proposed, to institute as a result a World Parliament.
