Permission for parties to appear No party has any right to be heard, either personally or by advocate, before a Judge when exercising his powers of revision: Provided that the Judge may, if he thinks fit, when exercising such powers hear any party, either personally or by advocate, and that nothing in this section shall be deemed to affect subsection 325(2). The Court invited parties to appear and argue in accordance with the provisions that give such permission so that justice is achieved without affecting the rights of any party, especially the Applicant, in the Court reaching a decision in this revision application. S/N fdui/hzr3Eu8HOjrdxEfsw 7 325(2) No order under this section shall be made to the prejudice of the accused unless he has had on opportunity of being heard, either personally or by advocate, in his own defence. Section 326 of CPC has to be read together with section 325(2) CPC as both provisions elaborate section 36 of the Courts Judiciary Act 1964 which provides that no party has the right to be heard before the High Court when the High Court exercises its powers of revision, provided that no final order can be made to the detriment of any party unless the party has been given an opportunity to be heard. Therefore, in the case of revision, it will be prudent for the High Court to allow both parties to appear. In this context, the concept of audi alteram partem is pivotal, where it means that no rights of a person can be affected without being given the opportunity to be heard. The Respondent’s Application To File An Affidavit The learned DPP had sought leave of this court to file an affidavit by the Investigating Officer to oppose the revision application. This application could be treated as an application to adduce fresh or additional evidence. The learned DPP had referred to the Court’s discretion in doing so and cited s.325 CPC read together with s.317 as grounds for the application. It is settled law that the exercise of a discretion must be in accordance with established judicial guidelines. In the case of adducing additional evidence, the guidelines were spelt out S/N fdui/hzr3Eu8HOjrdxEfsw in Ladd v. Marshal [1954] 3 All ER 745 in the form of three conditions. In elaboration of the conditions, Lord Parker CJ said in R v. Parks [1961] 3 All ER 633 at p. 634: Those principles can be summarized in this way. First, the evidence that it is sought to call must be evidence which was not available at the trial. Secondly, and this goes without saying, it must be evidence relevant to the issues. Thirdly, it must be evidence which is credible evidence in the sense that it is well capable of belief; it is not for this court to decide whether it is to be believed or not, but it must be evidence which is capable of belief. Fourthly, the court will after considering that evidence go on to consider whether there might have been a reasonable doubt in the minds of the jury as to the guilt of the appellant if that evidence had been given together with the other evidence at the trial. The statement of the law in R v. Parks [1961] 3 All ER 633 has been adopted and applied in local cases such as Mohamed bin Jamal v. PP [1964] 1 MLJ 254 and Che Din bin Ahmad v. PP [1976] 1 MLJ 289. The conditions for admitting additional evidence on appeal are cumulative rather than alternative, and it is the responsibility of the appellant to demonstrate that all have been satisfied. The court will only allow such evidence in the most exceptional circumstances. As Syed Agil Barakbah J (as he then was) said in Che Din Ahmad v. PP [1975] [1976] 1 MLJ 289 at pp. 289-290: Now, s. 317 of the criminal procedure code gives a discretion to the judge in hearing any appeal to allow S/N fdui/hzr3Eu8HOjrdxEfsw additional evidence if he thinks such is necessary. In considering such application the appellate court has always adopted the attitude that it is only in the most exceptional circumstances, and subject to what may be described as exceptional conditions, that the court is ever willing to listen to additional evidence (Mohamed bin Jamal v. Public Prosecutor [1964] CLJU 235; [1964] 1 LNS 235; [1964] 1 MLJ 354, 255 per Thomson LP, quoting Hallet J in the case of R v. Jordan [1956] 40 Cr App R 152, 154). It is clear, therefore, that not only the circumstances must be most exceptional but the subject which is proposed to be adduced by further evidence is subject to exceptional condition. It becomes necessary only if a failure of justice would result if such additional evidence was not taken and allowed when additional facts have come to light since the date of trial. The matter is left entirely to the discretion of the court. S.317 is the power given exclusively to a Judge under Part VII
