4 example, in the systems of minorities and mandates under the League of Nations and in the trusteeship system under the United Nations 10. Those were some of the first international systems to grant procedural capacity directly to individuals and private groups 11. Those antecedents, along the first half of the twentieth century, paved the way to the development, within the ambit of the United Nations and under the human rights treaties at global and regional levels, of the contemporary mechanisms of petitions or communications pertaining to violations of human rights 12. 11. With the consolidation of those mechanisms, granting direct access to individuals to the international instances, the recognition became evident, also at procedural level, that human rights, inherent to the human person, precede and are above the State and any other form of political organization, and the human being emancipated himself from the domination of the State, whenever it appeared arbitrary. The individual recovered his presence, for the vindication of his rights, at international level, presence which had been denied to him in the historical process of formation of the modern State but which manifested itself in the immediate concern with the human being in the original manuscripts of the so-called founding fathers of international law 13 (the derecho de gentes), notably in the perennial lessons - above all the De Indis - Relectio Prior, of 1538-1539 - of Francisco de Vitoria 14, the learned lecturer of Salamanca. 12. That transformation, proper of our times, corresponds to the recognition of the necessity that all the States, in order to avoid new violations of human rights, are made responsible for the way they treat all human beings who are under their jurisdiction. This would simply not have been possible without the consolidation of the right of individual petition, amidst the recognition of the objective character of 10. Cf., e.g., J. Stone, "The Legal Nature of Minorities Petition", 12 British Year Book of International Law (1931) pp. 76-94; M. Sibert, "Sur la procédure en matière de pétition dans les pays sous mandat et et quelques-unes de ses insuffissances", 40 Revue générale de Droit international public (1933) pp. 257-272; Jean Beauté, Le droit de pétition dans les territoires sous tutelle, Paris, LGDJ, 1962, pp. 1-256. 11. To them one ought to add other petitioning systems (such as those of Upper Silesia, of the Aaland Islands, of the Sa1ar and of Danzig), the system of navigation of the river Rhine, the experience of the Central-American Court of Justice (1907-1917), the caselaw of the Mixed Arbitral Tribunals and of the Mixed Claims Commissions, besides the International Prize Court proposed at the II Peace Conference of the Hague of 1907.
