A comparative analysis of the operation of the Mandates and the Trusteeship Systems is difficult for several reasons. In the first place, the Mandates System, because of its dissolution, has passed into oblivion whereas the Trusteeship System is a dynamic institution still in its evolutionary stage. Secondly, eight years of the actual working of the Trusteeship apparatus is too short a period to be compared with the twenty-six years of the League supervision over the execution of the Mandates. Thirdly, only nine out of the eleven Trust Territories (except Somaliland and the Pacific Islands) are under the administration of the former Mandatory Powers while Italian Somaliland had never been a Mandated Territory. Fourthly, the composition and functions of the supervisory organs, as we have seen in the previous Chapter, are fundamentally different. Fifthly, the predominance of the non-Colonial Powers in the General Assembly, who are keen for the speedy political emancipation of the twenty million inhabitants of the Trust Territories, has brought about a substantial change in the supervisory character of the Trust administration which was unknown in the preceding generation. We would, therefore, restrict ourselves to the study of the transformation of the high principles and noble objectives embodied in Article 76 of the Charter into positive action with relevant references to the Mandates System so as to estimate the extent of the political, economical, social and educational advancement of the indigenous inhabitants of the Trust Territories. Before we proceed with the analysis of the current questions affecting the Trust Territories, let us turn to the problem of sovereignty over Mandated and Trust Territories.
