In a country's evolution, there are different political, legal and economic stages and transformations. Also Romania has been subject to such transformations, one of these stages being represented by the dawn of a new constitutional order after the Revolution in 1989, which was followed by the establishment of a new constitutional framework by adopting, first of all, for the transition period, an act having the force of a "fundamental law" and, then, by adopting, in 1991, based on a referendum, the Romanian Constitution, which established the principles of the functioning of a State governed by the rule of law and the mechanisms for its functioning. The review of constitutionality, as part of this mechanism, was entrusted to the Constitutional Court as the guarantor for the supremacy of the Constitution and the only authority of constitutional jurisdiction in Romania. That was a first step, followed by a new challenge, i.e. the Europe-Atlantic Integration, that is to say Romania's accession to the North Atlantic Treaty and Romania's Accession to the European Union, which necessitated a revision of the Constitution in order to establish both the constitutional framework for the pre-accession stage and to determine in practice the relationship between national law and international order, namely the obligations of Romania stemming from such memberships. In this paper, we shall discuss some aspects relating to the Romanian Constitutional Court's case-law developments on priority or differences between national legal rules and international rules, the identical or divergent interpretation on points of law, the mutual reliance upon the case-law of such courts (ECHR, CJEU, CCR), presupposing a "judicial dialogue", especially since, for example, in March 2016, the Venice Commission adopted a Rule of Law Checklist which gives an overview of the extended scope of the rule of law which is based, inter alia, on the principle of legality, a principle with a broader scope, which also includes the relationship between international law and national law. In this context, we have in view the Constitutional Court's case-law developments with regard to the reliance upon the judgments of the European Court of Human Rights and, implicitly, upon the Convention for the Protection of Human Rights and Fundamental Freedoms, as a benchmark in the review of constitutionality, upon the case-law of the Court of Justice of the European Union and the effects and the priority of international treaties to which Romania is a party and which were concluded before the aforementioned constitutional transformations, regarded in terms of the case-law of the Constitutional Court of Romania.
