CCPR/C/81/D/962/2001 Page 6 article 9, paragraphs 1, 2 and 4, of the Covenant. On the same basis, the Committee concludes, however, that there has been no violation of article 9, paragraph 5, as it does not appear that the author has in fact claimed compensation for unlawful arrest or detention. 5.3 As to the complaint of a violation of articles 7 and 10, paragraph 1, of the Covenant, the Committee notes that the author has given a detailed account of the treatment he was subjected to during his detention, including acts of torture or ill-treatment and, subsequently, the deliberate denial of proper medical attention despite his loss of mobility. Indeed, he has provided a medical certificate attesting to the sequelae of such treatment. Under the circumstances, and in the absence of any counter-argument from the State party, the Committee finds that the author was a victim of multiple violations of article 7 of the Covenant, prohibiting torture and cruel, inhuman and degrading treatment. The Committee considers that the conditions of detention described in detail by the author also constitute a violation of article 10, paragraph 1, of the Covenant. 5.4 With regard to alleged violations of articles 6, paragraph 1 and 23, paragraph 1, of the Covenant, the Committee notes the author’s statement that his wife was beaten by soldiers, that Commander Mortos refused her request to travel to Bangui to receive medical attention, and that she died three days later. The Committee considers that these statements, which the State party has not contested although it had the opportunity to do so, and which the author has sufficiently substantiated, warrant the finding that there have been violations of articles 6, paragraph 1 and 23, paragraph 1, of the Covenant as to the author and his wife. 6. 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 before it reveal violations by the Democratic Republic of the Congo of articles 6, paragraph 1;7; 9, paragraphs 1, 2 and 4; 10, paragraph 1; and 23, paragraph 1, of the Covenant. 7. Under article 2, paragraph 3 (a), of the Covenant, the State party has an obligation to ensure that the author has an effective remedy available. The Committee therefore urges the State party (a) to conduct a thorough investigation of the unlawful arrest, detention and mistreatment of the author and the killing of his wife; (b) to bring to justice those responsible for these violations; and (c) to grant Mr. Mulezi appropriate compensation for the violations. The State party is also under an obligation to take effective measures to ensure that similar violations do not occur in future. 8. The Committee recalls that, by becoming a State party to the Optional Protocol, the Democratic Republic of the Congo recognized the competence of the Committee to determine whether there has been a violation of the Covenant or not and that, under 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 the event that a violation is established. Consequently, the Committee wishes to receive from the State party, within 90 days of the
