14 path, however, will not make us lose sight of the line of the horizon, in which the development emerges of the peremptory norms of international law (jus cogens) and of the obligations erga omnes of protection of the human being. As I allowed myself to ponder in my Separate Opinion (paragraph 28) in the Judgment of the Court on the merits (of 24.01.1998) in the present Blake case, "The consolidation of erga omnes obligations of protection, as a manifestation of the emergence itself of imperative norms of international law, would represent the overcoming of the pattern erected upon the autonomy of the will of the State. The absolute character of the autonomy of the will can no longer be invoked in view of the existence of norms of jus cogens. It is not reasonable that the contemporary law of treaties continues to aligning itself to a pattern from which it sought gradually to free itself, in giving expression to the concept of jus cogens in the two Vienna Conventions on the Law of Treaties. It is not reasonable that, by the almost mechanical application of postulates of the law of treaties erected upon the autonomy of the will of the State, one would restrain - as in the present case - a reassuring evolution, fostered above all by the opinio juris as a manifestation of the universal juridical conscience, to the benefit of all human beings". 40. Our purpose ought to lie precisely upon the doctrinal and jurisprudencial development of the peremptory norms of International Law (jus cogens) and of the corresponding obligations erga omnes of protection of the human being. It is by means of the development in this sense 35 that we will achieve to overcome the obstacles of the dogmas of the past, as well as the current inadequacies and ambiguities of the law of treaties, so as to bring us closer to the plenitude of the international protection of the human being. 35.
