4 4. That, considering Article 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 corresponds to a basic principle of law on the international responsibility of the State, supported by international jurisprudence, according to which the States must comply with their international conventional obligations in good faith (pacta sunt servanda) and, as previously held by the Court and pursuant to Article 27 of the Vienna Convention on the Law of Treaties of 1969, States cannot, for domestic order reasons, avoid the international responsibility which has already been established.2 The conventional obligations of the States Parties bind all powers and organs of the State. 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.
