REPORT No. 131/17 CASE 11.678 ADMISSIBILITY AND MERITS MARIO MONTESINOS MEJÍA ECUADOR OCTOBER 25, 2017 I. SUMMARY 1. On August 30, 1996 the Inter-American Commission on Human Rights (hereinafter, "the Commission" or “the IACHR”) received a petition filed by Alejandro Ponce-Villacís (hereinafter, "the petitioner”) alleging the international responsibility of the Republic of Ecuador (hereinafter, “the State,” "the Ecuadorian State" or "Ecuador") for the illegal and arbitrary arrest of Mario Montesinos Mejía (hereinafter, “the alleged victim”) by police officers in 1992, for the acts of torture inflicted on him, and for the lack of judicial protection in the criminal cases brought against him. 2. The State alleged that the case was inadmissible inasmuch as Mr. Montesinos had failed to exhaust domestic remedies prior to lodging the petition. It held that the arrest was made in accordance with domestic law and that due process guarantees were respected during the criminal proceedings. 3. After examining the points of fact and law presented by the parties, the Commission concludes that the State is responsible for violating the rights to humane treatment, personal liberty, a fair trial, and judicial protection set forth in Articles 5(1), 5(2), 7(1), 7(2), 7(3), 7(4), 7(5), 7(6), 8(1), 8(2), 8(2)(d), 8(3), 24, 25(1), and 25(2)(c) of the American Convention on Human Rights (hereinafter, “the American Convention” or “the Convention”) in connection with Articles 1(1) and 2 thereof, to the detriment of Mario Montesinos Mejía. The Commission further concludes that the State is responsible for the violation of Articles 1, 6, and 8 of the Inter-American Convention to Prevent and Punish Torture (hereinafter, “the IACPPT”). II. PROCEEDINGS BEFORE THE COMMISSION 4. The IACHR received the initial petition on August 30, 1996.
