4 for the Inter-American Commission on Human Rights: Patrick Robinson, Delegate Edith Márquez-Rodríguez, Attorney Domingo E. Acevedo, Attorney José Miguel Vivanco, Assistant Viviana Krsticevic, Assistant Ariel E. Dulitsky, Assistant II 13. The following paragraphs summarize the events, circumstances and processing of this case before the Commission as they were set forth in the application and its attachments submitted to the Court. 14. According to the application, on October 21, 1990, Mr. Ernesto Rafael Castillo-Páez, a university student and teacher, aged 22, was detained by officers of the Peruvian National Police near the Central Park of Group 17, Sector Two, Zone Two, of the Villa El Salvador district, Lima, Peru. According to witnesses to the events, when the agents detained him, “they stripped him of his glasses, beat him, handcuffed him and put him in the trunk of a police car, which then headed towards an unknown destination.” The arrest took place after members of the subversive group “Sendero Luminoso [Shining Path]” (hereinafter PCP-SL) had detonated explosives near the “Monumento a la Mujer” in the Villa El Salvador district. Mr. Castillo-Páez had apparently left home early that morning to study with a friend when he disappeared. 15.

On November 27, 1990, that Court declared the Prosecutor's appeal inadmissible, upheld the Examining Magistrate's ruling and ordered that all the documents needed for bringing “the appropriate criminal charges” be submitted. 17. The Commission also contends that, under Law No. 23.506 -governing habeas corpus and amparo in Peru- such a decision by the appellate court is final and constitutes res judicata. The above notwithstanding, the State Prosecutor filed a petition for nullification with the Court of Appeal, which did not grant the petition, whereupon the Prosecutor filed a complaint directly with the Supreme Court. The Supreme Court upheld the application and “ordered that the Court of Appeals grant the petition for nullification filed, as a result of which the case was brought before the Supreme Court of Justice.” On February 7, 1991, the Second Criminal Chamber of the Supreme Court issued a decision to “overturn the ruling and declare the protective remedy inadmissible.” 18. Based on evidence in the habeas corpus proceedings, a case was brought before Lima's Fourteenth District Criminal Court against several officials involved in the
