June 26, 2003, June 3, 2003, July 9, 2003 and January 23, 2003, at which time the Chilean State was bound by the obligation to respect and guarantee the rights enshrined in the American Convention. 25. The Commission has jurisdiction ratione loci inasmuch as the alleged violations took place within the territory of a State party to the American Convention. B. Other requirements of admissibility 1. Exhaustion of domestic remedies 26. As a requirement for admissibility, Article 46(1) of the American Convention requires that the remedies under domestic law have been pursued and exhausted. The petitioner argues that he has pursued and exhausted the domestic remedies available under Chilean legislation. He claims that, through judgments handed down on June 26, 2003, June 3, 2003, July 9, 2003 and January 23, 2003, domestic remedies were exhausted. For its part, the State did not deny or contest the petitioner's assertion. Consequently, the Commission considers that the requirement of Article 46(1) of the American Convention is fulfilled. As well, the petitioner cites three judgments of the Civil Chamber of the Supreme Court of Chile issued during 2002-2003 (supra, paragraph 11), the last of them on April 15, 2003, in which the Supreme Court rejected three appeals for cassation denying reparations, to demonstrate the constant practice of the Supreme Court in denying this remedy. 27. In response to the petition, the State submitted no observations regarding the failure to exhaust domestic remedies. The Inter-American Court of Human Rights has repeatedly held that in order to be timely, the objection that domestic remedies have not been exhausted should be raised during the first stages of the proceeding; otherwise, it will be presumed that the respondent State tacitly has waived this defense. 28. The Commission therefore considers that the Chilean State waived the objection of failure to exhaust domestic remedies, because it did not present this objection at the first procedural opportunity, i.e. in its response to the petition that initiated the proceedings. Consequently, the Commission considers that the requirement of Article 46(1)(a) of the American Convention is fulfilled. 2. Timeliness of the petition 10
