The General Assembly, at its 160th Plenary Meeting on November 18, 1948, adopted resolution 224 (III) on the effects of Administrative Unions on Trust Territories which, inter alia, called upon the Trusteeship Council to investigate this question in all its aspects and to report to the next (fourth) session of the General Assembly on the results of its investigations and actions taken, and also, whenever appropriate, to request an advisory opinion of the International Court of Justice as to whether such Unions were within the scope of, and compatible with, the provisions of the Charter and the Trusteeship Agreements. Pursuant to this resolution, the Trusteeship Council created a Committee on Administrative Unions to undertake preparatory work to facilitate the investigations. This Committee, in addition to preparing documents, made an interim report and a final report.
