opening of the oral proceedings. Once this problem had been corrected, the oral proceedings commenced and are still underway, with the statements of the accused being heard. 20. The Court considers it necessary to recall and underline that prompt observance of the State obligation to advise the Court of how it is implementing each aspect ordered by the Court in the judgment is essential in order to assess the status of compliance with the judgment as a whole. Moreover, this obligation is not fulfilled with the mere formal presentation of a document to the Court, but is twofold in nature and, for its effective compliance, requires the formal presentation of a document within the established time frame, and that it presents specific, true, recent and detailed information on the aspects to which this obligation relates. 13 21. In this regard, the Court finds it pertinent to remind Peru, as it has on previous occasions, 14 that without the appropriate information from the State, this Court is unable to exercise its function of monitoring the execution of the judgments it delivers. The provision of sufficient information on the measures adopted is a State obligation that has been established by this Court, 15 and the OAS General Assembly has reiterated “the need for States Parties to provide, in a timely fashion, the information requested by the Court, in order to enable it to meet in full its obligation to report to the General Assembly on compliance with its judgments.” 16 22. Thus, Peru must adopt all necessary measures to comply with the decisions of the Court in the Judgment (supra having seen paragraph 1). This obligation includes the State’s obligation to provide information on the measures adopted to comply with the aspects ordered in the said Judgment. 23. Consequently, and in order to assess promptly and adequate the information forwarded by the representatives and the State on January 29 and 30, 2013 (supra considering paragraphs 18 and 19), the Court considers it essential that the State submit a detailed, complete and updated report on the measures taken to comply with all the measures of reparation ordered in the Judgment that remain pending. Also, the Court must receive the respective observations of the representatives of the victims and the InterAmerican Commission. 13 Cf. Case of Bámaca Velásquez v. Guatemala. Monitoring compliance with judgment. Order of the InterAmerican Court of Human Rights of July 4, 2006, seventh considering paragraph, and Case of Caballero Delgado and Santana v. Colombia. Monitoring compliance with judgment. Order of the Inter-American Court of Human Rights of February 27, 2012, fifth considering paragraph. 14 In the context of the proceeding on monitoring compliance with judgment, the Court has constantly reiterated to the State that it has an obligation to provide information on the measures adopted to comply with the reparations ordered. See, Case of Gómez Palomino v. Peru. Monitoring compliance with judgment.
