12 34. I could not conclude this Separate Opinion in the present case of Hilaire versus Trinidad and Tobago without a last line of reflections, de lege ferenda, on the international compulsory jurisdiction. The "judicial decisions", referred to in the enumeration of the formal sources and evidences of International Law, set forth in Article 38(1)(d) of the Statute of the ICJ 37, certainly are not limited to the case-law of the ICJ itself 38. They likewise comprise, nowadays, the judicial decisions of the international tribunals (Inter-American and European Courts) of human rights, of the ad hoc International Criminal Tribunals (for ex-Yugoslavia and for Rwanda), of the International Tribunal for the Law of the Sea, of other international and arbitral tribunals, as well as of national tribunals in matters of international law 39. Throughout the last years the old ideal of international justice has been revitalized and has gained ground, with the considerable expansion of the international judicial function, reflected in the creation of new international tribunals; the work of these latter has been enriching contemporary international case-law, contributing to assert the aptitude of International Law to regulate adequately the juridical relations in distinct domains of human activity. 35. In this sense, in my aforementioned Separate Opinion in the case of Blake versus Guatemala, in warning as to the necessity to establish the juridical bases of a minimally institutionalized international community, I pointed out that "(...) With the evolution of the International Law of Human Rights, it is Public International Law itself which is justified and legitimized, in affirming juridical principles, concepts and categories proper to the present domain of protection, based on premises fundamentally distinct from those which have guided the application of its postulates at the level of purely inter-State relations. (...) The norms of the law of treaties (...) can greatly enrich with the impact of the International Law of Human Rights, and develop their aptitude to regulate adequately the legal relations at inter-State as well as intra-State levels, under the respective treaties of protection. (...)" 40. 36. The Inter-American Court of Human Rights, by means of the Judgments on Preliminary Objections which it has just adopted in the cases of Hilaire, Benjamin, and Constantine, as well as its earlier Judgments on Competence in the cases of the Constitutional Tribunal and Ivcher Bronstein, has safeguarded the integrity of the American Convention on Human Rights, has been master of its own jurisdiction and has acted in accordance with the high responsibilities accorded to it by the American Convention. The same can be said of the European Court of Human Rights, by means of its Judgment on Preliminary Objections in the case Loizidou versus Turkey, in so far as the European Convention on Human Rights is concerned. Thus, the two existing 37 . As "subsidiary means for the determination of rules of law". 38 .
