a reasonable period. In that connection, the IACHR observes that the original petition was received on June 27, 2003. The incidents complained of in the petition occurred over the period from November 2001 to January 2003. The IACHR considers that the petition was lodged within a reasonable period of time. E. Duplication of proceedings 41. Article 46(1)(c) of the Convention provides that admissibility of a petition by the Commission requires that the subject of the petition or communication is not pending in another international proceeding for settlement. Article 47(d) of the Convention also stipulates that the Commission shall declare inadmissible any petition that is substantially the same as one previously studied by the Commission or by another international organization. 42. From the statements of the Petitioners, it does not appear that the petition is pending in any other international proceeding or forum, or that it is substantially the same as any previously studied by the Commission or by another international organization. The Commission therefore considers that in the instant case the requirements for admissibility in Articles 46(1)(c) and 47(d) of the Convention have been met. F. Nature of the facts alleged 43. For purposes of admissibility, the IACHR has to determine whether the facts stated in the petition tend to establish a violation of rights set forth in the American Convention, as required under Article 47(b), or whether the petition must be dismissed as "manifestly groundless" or "obviously out of order" under Article 47(c). 44. The standard by which to assess these extremes are different from the one needed to decide the merits of a petition. The IACHR must do a prima facie evaluation, not to establish the existence of a violation but rather to examine whether the petition states facts that tend to establish a potential or apparent violation of a right guaranteed by the Convention. That examination is a summary analysis that does not imply any prejudgment or advance opinion on the merits of the petition. By establishing two clearly separate phases—one for admissibility and the other for the merits—the Commission's own Rules of Procedure reflect the distinction between the evaluation the Commission must make to declare a petition admissible, and the evaluation required to establish a violation. 45. The Petitioners have made allegations, which, if proven to be true, would tend to characterize violations of Articles 1(1), 2, 5, 8, 13, and 25 of the American Convention. The allegations are not "manifestly groundless" or "obviously out of order." Therefore, without prejudice to the merits of the case, the Commission considers that the requirements of Article 47(b) and (c) of the American Convention have been met with respect to Articles 1(1), 2, 5, 8, 13, and 25 of the Convention. IV. CONCLUSIONS 46. The Commission considers that it has competence to take cognizance of this petition and that it is admissible as regards the requirements for admissibility contained in Articles 46 and 47 of the American Convention on Human Rights, and as regards the alleged violations of Articles 1(1), 2, 5, 8, 13, and 25 of the American Convention. 47. On the basis of the aforementioned arguments as to facts and law, and without prejudice to the merits of the case, THE INTER-AMERICAN COMMISSION ON HUMAN RIGHTS, DECIDES: 1. To declare the instant case admissible as regards the presumed violations of rights protected by Articles 1(1), 2, 5, 8, 13, and 25 of the American Convention; 9
