Planning for the UN Fiscal Commission by the Princeton Mission began as early as March 1943 and would require a utilisation of the Mission’s networks to bring the body to fruition in the United Nations. The blueprint of the Commission was greatly ambitious, but decisions made by the international community affecting its establishment in the Economic and Social Council would render it unable to succeed its predecessor in fundamental ways. The far from widespread support for its creation as well as the existence of the new specialised agencies would moreover have long-lasting repercussions for the Commission’s terms of reference and scope of work.
