2 Congressional Employees(Aguado-Alfaro et al.) v. Peru, which issues, in my view, bear the most relevance, namely: (a) performance of conventionality control; (b) conventional obligations of protection as obligations of result; (c) the engagement of State responsibility at the domestic-law and international-law levels; and (d) access to justice and the extension of the material scope of jus cogens. The stage has therefore been set for the formulation of my considerations and final advice. II. Performance of Conventionality Control. 6. It took more than a couple of centuries for domestic public law to reach a point of cohesion and get arranged into a hierarchy such that it now has a mechanism to control the “constitutionality” of laws and administrative decisions.2 This control has become a means for the protection of the rights of citizens in general and, a fortiori, of all persons subject to state jurisdiction, in a State in which the Rule of Law prevails.3 Such evolution of domestic law did, inevitably, have an effect on international-law scholars, who took note of such developments.4 Starting in the mid 20th century, this got labeled the “internationalization” of constitutional law while, more recently, over the past two decades, there has been talk of the “constitutionalization" of International Law. 7. Both currents of thought have fostered greater cohesion in the legal system, as well as greater interaction between the international and domestic legal systems in the protection of human rights.5 In the context of such broader doctrinal dimension, it was recognized that, at the international level proper, human rights treaties present a “constitutional” dimension, which is herein referred to not in connection with its position within the hierarchy of domestic legal norms - domestic law being, anyway, a hostage of the provisions of national constitutions and therefrom projecting, with certain variations, onto the international sphere – but, rather, in the much more advanced sense that, in the international sphere proper, they constitute a constitutional legal system of respect for human rights. 8. In reference to the European Convention on Human Rights, the European Court of Human Rights actually used the phrase "constitutional instrument of European public order (`instrument constitutionnel de l'ordre public européen')" in the Case of Loizidou v. Turkey (Preliminary Objections, 1995, para. 75), and the InterAmerican Court started to address that issue in this Case of the Dismissed Congressional Employees(Aguado-Alfaro et al.) v.
