4 21. The brief of November 18, 2009 by which the State forwarded a report related to the compliance with the Judgment. Considering: 1. That it is an inherent power of the judicial functions of the Court to monitor compliance with its decisions. 2. That the State of Peru has been a State Party to the American Convention on Human rights (hereinafter, the “American Convention”) since July 28, 1978, and that it accepted the binding jurisdiction of the Court on January 21, 1981. 3. That, pursuant to Article 67 of the American Convention, State parties must fully comply with the judgments entered by the Court in time fashion. Furthermore, Article 68(1) of the American Convention stipulates that ““[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, the States must ensure that the rulings set out in the decisions of the Court are implemented at the domestic level.3 4. That the obligation to comply with the rulings of the Court conforms to a basic principle of the law on the international responsibility of States, under which States are required to fulfill their international treaty obligations in good faith (pacta sunt servanda) and, as previously held by the Court and provided for in Article 27 of the Vienna Convention on the Law of Treaties of 1969, States cannot invoke their municipal laws to escape from their pre-established international responsibility. . The treaty obligations of States Parties are binding on all State powers and organs. 4. 5. That the States Parties to the Convention must ensure compliance with its provisions and their inherent effects (effet utile) within their respective domestic legal systems. This principle applies not only in connection with the substantive provisions of human rights treaties (i.e. those dealing with provisions on protected rights) but also in connection with procedural rules, such as the ones concerning compliance with the decisions of the Court. Such obligations are intended to be interpreted and enforced in a manner such that the protected guarantee is truly practical and effective, taking into account the special nature of human rights treaties5. * * * Simple, prompt and effective recourse for the determination of rights 3 Cf.
