complainant's part). The Committee considers, as a consequence, that the complainant has failed to demonstrate that, at the time of the communication, he was a victim of the alleged failure of the State party to abide by the contended obligation under the Convention to exhaust the full measure of avenues open to it in the attempt to procure the alleged offender's extradition. 6.5 Moreover, with respect to (b), the Committee notes that the complainant did not engage domestic remedies in Spain by becoming a civil party to the proceedings to obtain the extradition of General Pinochet. Further, with regard to his complaints against the Spanish Minister for Foreign Affairs, the Committee notes that the complainant did not make use of the remedy of amparo, which the State party contends is an available and effective remedy, citing a number of cases before the Constitutional Court in support of this proposition, whereas the complainant claims thatamparo would not have resulted in any relief, citing relevant case-law. In the circumstances, the Committee is not in a position to decide that recourse to such remedies would have been a priori futile and thus not required for purposes of article 22, paragraph 5 (b) of the Convention. 6.6 With respect to (c), the Committee notes that the complainant's claims with regard to torture committed by Chilean authorities are ratione personae justiciable in Chile and in other States in whose territory General Pinochet may be found. However, to the extent that General Pinochet was not in Spain at the time of the submission of the communication, the Committee would consider that articles 13 and 14 of the Convention invoked by the complainant do not apply ratione personae to Spain. In particular, his "right to complain to, and to have his case promptly and impartially examined by, [the] competent authorities", and his claim to compensation would be justiciable vis-à-vis the State responsible for the acts of torture, i.e. Chile, not Spain. 6.7 With respect to (d), the Committee observes that the State party possesses extraterritorial jurisdiction over acts of torture committed against its nationals. The Committee recalls that one of the objects of the Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment is to avoid any impunity to persons having committed such acts. The Committee observes that, based upon the State party's law, and in conformity with articles 5, paragraph 1 (c), and 8, paragraph 4, of the Convention, the State party sought the extradition of General Pinochet for trial in Spain. There is every indication that Spain would have brought General Pinochet to trial, once he were to be found on its territory, further to the indictment of 4 July 1996 of the Juez Central de la Audiencia Nacional de España. The Committee observes, however, that while the Convention imposes an obligation to bring to trial a person, alleged to have committed torture, who is found in its territory, articles 8 and 9 of the Convention do not impose any obligation to seek an extradition, or to insist on its procurement in the event of a refusal. In this connection, the Committee refers to article 5, paragraph 1 (c), of the
