Court of Criminal Appeal reViews the conviction and sentence only on the basis of the legal arguments presented by the defendant's counsel and does not undertake a full rehearing of the facts. According to the author, article 14, paragraph 5, requires a full rehearing of the facts. In this context, the author also states that no possibility of direct appeal to the High Court exists, but that one has to request leave to appeal, which was refused by the Court in his case. his right to call witnesses only through his solicitor, not independently. According to the author, his solicitor was accredited to the Supreme Court of Queensland. He argues that the State party should take responsibility for the supervision of solicitors accredited to the courts, to see whether they comply with their obligations under the law. The author further contends that the signed interview with Jensen, referred to by the State party, was obtained under the influence of drugs, and that this would have been revealed if he would have been called as a witness, especially because the evidence that the author was not involved in any drug deal was corroborated by other witnesses. 5.6 As regards the State party's claim that he has not exhausted domestic remedies with regard to his complaint about police treatment, the author submits that, in fact, he has addressed complaints to the Police Complaints Tribunal, the Human Rights and Equal Opportunity Commission and the Parliamentary Ombudsman, all to no avail. 5.2 The author reiterates that the racist attitude of the police, resulting in violence and in fabrication of the evidence against him, led to his conviction for an offence of which he had no knowledge. He submits that the evidence against him was wholly circumstantial, except for the alleged admissions to the police, which were fabricated. He claims that the failure of the judge to rule the admissions inadmissible as evidence constitutes a denial of justice, in violation of article 14, paragraph 1; in this context, he submits that the judge did not admit evidence on behalf of the defence from a solicitor who had visited the author at the police station and who had seen that the author was upset and crying, allegedly as a result of the treatment he received from the policemen. The author also contends that there were inconsistencies in the evidence against him, that some of the prosecution witnesses were not reliable, and that the evidence was insufficient to warrant a conviction. In this context, the author points out that he was acquitted on two other charges, where the evidence was purely circumstantial, and that his conviction on the one charge apparently was based on the evidence that he had admitted his involvement to the policemen upon arrest. Issues and proceedings before the Committee 6.1 Before considering any claim contained in a communication, the Human Rights Committee must, in accordance with rule 87 of its rules of procedure, decide whether or not it is admissible under the Optional Protocol to the Covenant. 6.2 The Committee observes that the author's allegations relate partly to the evaluation of evidence by the court. It recalls that it is generally for the appellate courts of States parties to the Covenant, and not for the Committee, to evaluate the facts and evidence in a particular case, unless it is clear that a denial of justice has occurred or that the court violated its obligation of impartiality. The author's allegations and submissions do not show that the trial against him suffered from such defects. In this respect, therefore, the author's claims do not come within the competence of the Committee. Accordingly, this part of the communication is inadmissible as incompatible with the provisions of the Covenant, under article 3 of the Optional Protocol. 5.3 The author further submits that it is apparent from the trial transcript that he had difficulties understanding the English that was used in court. He claims that, as a result, he misunderstood some of the questions put to him. He claims that his solicitor never informed him that he had the right to have an interpreter and that, moreover, it was the trial judge's duty to ensure that the trial was conducted fairly and, consequently, to call an interpreter as soon as he noticed that the author's English was insufficient. 6.3 As regards the author's complaint that Jensen was not called as a witness during the trial, the Committee notes that the author's defence lawyer, who was privately retained, was free to call him but, in the exercise of his professional judgement, chose not to do so. The Committee considers that the State party cannot be held accountable for alleged errors made by a defence lawyer, unless it was or should have been manifest to the judge that the lawyer's behaviour was incompatible with the interests of justice. In the instant case, there is no reason to believe that counsel was not using his best judgement, and this part of the communication is therefore inadmissible under article 2 of the Optional Protocol. 5.4 The author further notes that one of the appeal judges who heard his appeal after the first trial also participated in the consideration of his appeal after the retrial. He claims that this shows that the Court of Criminal Appeal was not impartial, in violation of article 14, paragraph 1. 6.4 With regard to the author's complaint about the review of his conviction, the Committee notes from the judgement of the Court of Criminal Appeal, dated 4 July 1986, that the Court did evaluate the evidence 5.5 The author maintains that article 14, paragraph 5, was violated in his case, because the 17
