4 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.1 4. That, in consideration of section 67 of the American Convention which stipulates that the judgment of the Court shall be final and shall not be subject to appeal, such judgment shall be fully and promptly complied with by the State. 5. 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.2 6. 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 treaties.3 7. That those States Parties to the American Convention that have accepted the binding jurisdiction of the Court are under a duty to fulfill the obligations set by the Tribunal. This obligation includes the State’s duty to report on the measures adopted to comply with such decisions of the Court. Timely fulfillment of the State’s obligation to report to the Corut on the exact manner in which it is complying with each of the aspects ordered by the later is essential to evaluate the whole status of compliance in this case4. 1 Case of Baena Ricardo et al v.
