15 10. That Article 68(1) of the 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.” 11. That the obligation to comply with the provisions of the Court’s judgments corresponds to a basic principle of the law of the international responsibility of the State, supported by international case law, according to which, a State must comply with its international treaty obligations in good faith (pacta sunt servanda) and, as this Court has already indicated and as established in Article 27 of the 1969 Vienna Convention on the Law of Treaties, a party may not invoke the provisions of its internal law as justification for its failure to perform a treaty 1. 12. That the obligation to report to the Court is not complied with by the mere formal presentation of a document to the Court, but is a dual obligation, which, for effective compliance, requires the formal submission of a document within the time limit, with specific, true, current and detailed information on the issues to which this obligation refers. 13. That the State must comply with all the elements decided by the Court in its Orders, and submit periodic reports on all the measures that it has adopted to protect the lives and safety of the persons protected by the provisional measures in this case; on the investigation of the facts that gave rise to them, and on the measures taken to allow the petitioners to participate in the implementation of those measures. The State’s obligation to inform the Court of the manner in which it is complying with the Court’s decision is fundamental for the assessment of the case. 14. That, in the terms of Article 65 of the American Convention, [t]o each regular session of the General Assembly of the Organization of American States the Court shall submit, for the Assembly's consideration, a report on its work during the previous year. It shall specify, in particular, the cases in which a state has not complied with its judgments, making any pertinent recommendations. 15. That Article 30 of the Statute of the Court establishes that, [t]he Court shall submit a report on its work of the previous year to each regular session of the OAS General Assembly. It shall indicate those cases in which a State has failed to comply with the Court's ruling. It may also submit to the OAS General Assembly proposals or recommendations on ways to improve the inter-American system of human rights, insofar as they concern the work of the Court. 16. That, since the State has not implemented effectively the measures ordered by the Court, has not investigated the facts that gave rise to them, has not allowed the petitioners to take part in the planning and coordination of the means of protection, and has not complied fully with the reporting obligation, should the current situation persist, the Court, in application of Article 65 (supra fourteenth considering paragraph) and Article 30 of its Statute (supra fifteenth considering paragraph), will include this Order in its Annual Report for 2003, so that it may be 1 Cf.
