CAT/C/31/D/188/2001 Page 21 10.4 Article 12 of the Convention, the Committee notes that article 12 of the Convention places an obligation on the authorities to proceed automatically to a prompt and impartial investigation whenever there is reasonable ground to believe that an act of torture or ill-treatment has been committed, no special importance being attached to the grounds for the suspicion. 13 10.5 The Committee notes that the complainant maintains that he complained of acts of torture committed against him to the judge at his trials in 1992 and 1995. The complainant states that in 1992 he requested a medical examination, which was refused, and that in 1995 he sought the protection of the judge of the Tunis court of first instance against the torture inflicted on him daily at the prison. The Committee notes that the State party challenges the complainant’s claim that he was denied a medical examination, without commenting on the treatment of which the complainant complained to the judge or providing the results of the medical checks allegedly carried out on Mr. Abdelli while he was being held. The Committee also takes note of the State party’s failure to comment on the precise allegations set out above relating to 1995. Lastly, the Committee notes the existence of detailed and substantiated information provided by the complainant concerning his hunger strikes in Tunis central prison in 1995 and in Grombalia prison from 28 November to 13 December 1997, mounted in order to protest against the treatment he had suffered and to secure medical care. The complainant refers to letters sent to the prisons administration following his hunger strikes, which produced no result. The Committee notes that the State party has not commented on this information. The Committee considers that these elements, taken together, should have been enough to trigger an investigation, which was not held, in breach of the obligation to proceed to a prompt and impartial investigation under article 12 of the Convention. 10.6 The Committee also observes that article 13 of the Convention does not require either the formal lodging of a complaint of torture under the procedure laid down in national law or an express statement of intent to institute and sustain a criminal action arising from the offence, and that it is enough for the victim simply to bring the facts to the attention of an authority of the State for the latter to be obliged to consider it as a tacit but unequivocal expression of the victim’s wish that the facts should be promptly and impartially investigated, as prescribed by this provision of the Convention.14 10.7 The Committee notes, as already indicated, that the complainant explains that he did complain to judges in 1992 and 1995 of the treatment inflicted on him, resorted to hunger strikes and wrote to the prison authorities to complain about the conditions imposed on him. The Committee regrets that the State party has not responded or provided the necessary clarification on these points. Moreover, and notwithstanding the jurisprudence under article 13 of the Convention, the Committee notes the State party’s position maintaining that the complainant should have made formal use of domestic remedies in order to lodge his complaint, for example by presenting to the court a certificate proving that a complaint had been lodged with the office of the public prosecutor, or displaying obvious traces of torture or ill-treatment, or submitting a medical report. On this latter point, to which the Committee wishes to draw its attention, it is 13 Communication No. 59/1996 (Encarnación Blanco Abad v. Spain). 14 Communications No. 6/1990 (Henri Unai Parot v. Spain) and No. 59/1996 (Encarnación Blanco Abad v. Spain).
