conditions of detention described, as well as the violent and abusive behaviour both of certain prison guards and of other inmates, as apparently acquiesced in by the prison authorities, are seriously in violation of the author’s right, as a prisoner, to be treated with humanity and with respect for his inherent dignity, in violation of article 10, paragraph 1. As at least some of the acts of violence against the author were committed either by the prison guards, upon their instigation or with their acquiescence, there was also a violation of article 7. There is also a specific violation of article 10, paragraph 2, arising from the failure to segregate the author, pre-trial, from convicted prisoners. 8. The Human Rights Committee, acting under article 5, paragraph 4, of the Optional Protocol to the International Covenant on Civil and Political Rights, is of the view that the facts as found by the Committee reveal violations by the Philippines of article 7, article 9, paragraphs 1, 2 and 3, and article 10, paragraphs 1 and 2, of the Covenant. 9. In accordance with article 2, paragraph 3 (a), of the Covenant, the State party is under an obligation to provide the author with an effective remedy. In respect of the violations of article 9 the State party should compensate the author. As to the violations of articles 7 and 10 suffered while in detention, including subsequent to sentence of death, the Committee observes that the compensation provided by the State party under its domestic law was not directed at these violations, and that compensation due to the author should take due account both of the seriousness of the violations and the damage to the author caused. In this context, the Committee recalls the duty upon the State party to undertake a comprehensive and impartial investigation of the issues raised in the course of the author’s detention, and to draw the appropriate penal and disciplinary consequences for the individuals found responsible. As to the imposition of immigration fees and visa exclusion, the Committee takes the view that in order to remedy the violations of the Covenant the State party should refund to the author the moneys claimed from him. All monetary compensation thus due to the author by the State party should be made available for payment to the author at the venue of his choice, be it within the State party’s territory or abroad. The State party is also under an obligation to avoid similar violations in the future. 7.4 As to the claims concerning the author’s mental suffering and anguish as a consequence of being sentenced to death, the Committee observes that the authors’ mental condition was exacerbated by his treatment in, as well as the conditions of, his detention, and resulted in documented long-term psychological damage to him. In view of these aggravating factors constituting further compelling circumstances beyond the mere length of time spent by the author in imprisonment under a sentence of death,13 the Committee concludes that the author’s suffering under a sentence of death amounted to an additional violation of article 7. None of these violations were remedied by the Supreme Court’s decision to annul the author’s conviction and death sentence after he had spent almost fifteen months of imprisonment under a sentence of death. 7.5 As to the author’s claims under article 9 the Committee notes that the State party has not contested the factual submissions of the author. Hence, due weight must be given to the information submitted by the author. The Committee concludes that the author was not informed, at the time of arrest, of the reasons for his arrest and was not promptly informed of the charges against him; that the author was arrested without a warrant and hence in violation of domestic law; and that after the arrest the author was not brought promptly before a judge. Consequently, there was a violation of article 9, paragraphs 1, 2 and 3, of the Covenant. 10. Bearing in mind that, by becoming a party to the Optional Protocol, the State party has recognized the competence of the Committee to determine whether there has been a violation of the Covenant or not and that, pursuant to article 2 of the Covenant, the State party has undertaken to ensure to all individuals within its territory and subject to its jurisdiction the rights recognized in the Covenant, and to provide an effective and enforceable remedy in case a violation has been established, the Committee wishes to receive from the State party, within 90 days, information about the measures taken to give effect to the Committee's Views. The State party is also requested to publish the Committee’s Views. 13 Johnson v. Jamaica, Case No. 588/1994, Views adopted on 22 March 1996; Francis v. Jamaica, Case No. 606/1994, Views adopted on 25 June 1995. 121
