6 29. Article 46(1)(b) of the American Convention provides that for a petition to be admissible before the Commission it must be lodged within a period of six months from the date on which the party alleging violation of his rights was notified of the final judgment; article 32 of the Commission’s Rules of Procedure provides that in those cases in which the exceptions to the requirement of prior exhaustion of domestic remedies are applicable, the petition shall be presented within a reasonable period of time, as determined by the Commission. For this purpose, the Commission shall consider the date on which the alleged violation of rights occurred and the circumstances of each case. 30. It can be inferred from the instant case file that the latest judicial decisions regarding the requests of Messrs. Néstor Rolando López, Miguel Ángel González Mendoza and José Heriberto Muñoz Zavala, to be returned to the Province of Neuquén were adopted by the Supreme Court of Justice of the Nation in three rulings issued on August 6, 1998, that is, two and a half months before they lodged their petition before the Commission on October 15, 1998. Therefore, they were filed within the time period of six months established by the American Convention as a requirement for admission. 31. In the case of Mr. Hugo Alberto Blanco, it is on record in the case file that the Second Criminal Chamber of the city of Neuquén issued Interlocutory Order No. 333/04 on November 23, 2004, denying a habeas corpus petition containing a request for his transfer. The complaint was submitted by the petitioners to the IACHR in a communication received on December 8, 2004, and therefore was presented within the six months time period established by the American Convention as a requirement for admitting the petition. 32. It can be inferred from the information presented in the instant case that the latest judicial appeals decided in the cases of Messrs. Julio Eduardo Gómez and Cristian Eduardo Crespo, were those in which decisions were handed down by the Superior Court of Neuquén on September 24, 2002 (Decision No. 26/2002) and October 24, 2002 (Interlocutory Decision No. 109). However, the complaints specifically regarding these two alleged victims were filed by the petitioners in a communication received by the IACHR on September 24, 2003. Thus, both final decisions were adopted at least eleven months before the petitions regarding Messrs. Gómez and Crespo were lodged, and therefore the petitions were submitted after the time period of six months, established as a requirement for admissibility by the American Convention, had expired. 33. Regarding the rest of the alleged victims, the Commission does not have the necessary specific information to decide on whether this admissibility requirement has been met. 34. With respect to this matter, the Commission notes that article 46(1)(b) establishes a six month time period for the petition to be lodged starting from the date on which the “party alleging violation of his rights” was notified of the final judgment. Therefore, in cases such as the one at hand, in which specific violations are alleged regarding each one of the alleged victims, and in which each person has his own proceedings for the exhaustion of domestic remedies, the Commission must examine, individual by individual, whether the time period requirement for the lodging of a petition has been met. 35. Therefore, the IACHR concludes that the petitions regarding Néstor Rolando López, Miguel Ángel González Mendoza, José Heriberto Muñoz Zavala and Hugo Alberto Blanco were lodged within the time period established by article 46(1)(b) of the Convention. D. Duplication of proceedings and international res judicata 36. It cannot be inferred from the case file that the petition is pending in another international proceeding for settlement, nor that it is substantially the same as one previously studied by this or by another international organization. Therefore, it is the opinion of the Commission that the requirements established by articles 46(1)(c) and 47(d) of the Convention have been met. E. Characterization of the Facts Alleged
