2 b) hold a public act of acknowledgement of responsibility (operative paragraph ten of the Judgment). 3. The brief of August 19, 2010, by which the Republic of Argentina (hereinafter “the State” or “Argentina”) presented its report about compliance with the outstanding points of the Judgment . 4. The briefs of July 8 and September 20, 2010 and their annexes, by which the representatives of the victim (hereinafter “the representatives”) presented information about the compliance with the Judgment and their comments on that set forth by the State concerning the issue. 5. The communication of October 8, 2010, by which the Inter-American Commission on Human Rights (hereinafter “the Inter-American Commission” or “the Commission”) presented its comments on the information issued by the State and on the briefs of the representatives regarding compliance with the Judgment. CONSIDERING THAT: 1. Monitoring of compliance with its decisions is an inherent power of the judicial functions of the Court. 2. Argentina has been a State Party to the American Convention on Human Rights (hereinafter “the American Convention” or “Convention”) since September 5, 1984, and accepted the compulsory jurisdiction of the Court on the same date. 3. Pursuant to Article 68(1) of the American Convention, “[t]he States Parties to the Convention undertake to comply with the judgment of the Court in any case to which they are parties.” Therefore, States must ensure that the rulings set out in the decisions of the Court are implemented domestically.1 4. In view of the final and incontestable character of the judgments of the Court, as established in Article 67 of the American Convention, the State should comply with them fully and promptly. 5. The duty to comply with the decisions in the Court’s judgments corresponds to a basic principle of the law of international responsibility of the State, supported by international jurisprudence, according to which States must comply with their international treaty obligations in good faith (pacta sunt servanda). 6. The States Parties to the Convention must guarantee compliance with the provisions thereof and their effectiveness (effet utile) within their respective domestic legal systems. This principle is applicable not only with regard to the substantive norms of human rights treaties (that is, those which contain provisions concerning protected rights), but also with regard to procedural norms, such as those referring to compliance with the decisions of the Court. These obligations are to be interpreted and enforced in a manner such that the protected guarantee is truly practical and effective, bearing in mind the special nature of 1 Cf.
