That the hairbrushes where DNA of the 1st, 3rd, 4th and 5th accused persons were found were retrieved from the pockets of the 3rd and 4th accused persons. [38] Foremost, we are of the considered view that failure to cross-examine the accused persons was not fatal to the prosecution’s case and that the court must still evaluate the totality of the evidence to determine the guilt of the accused persons. Failure to cross-examine does not necessarily amount to admission. In Wong Swee Chin v Public Prosecutor [1981] 1 MLJ 212, the Federal Court had held that there was a misdirection by the trial judge when he held that the failure of the defence to cross-examine the witnesses on the ammunition found in the trouser pockets of the appellant constituted an admission of the charge of possession by the appellant. However, the Federal Court found that this did not affect the correctness of the verdict as the totality of the evidence pointed conclusively to the guilt of the appellant. We are of the considered view that although the prosecution did not cross-examine the accused persons in respect of some of the evidence, it does not tantamount to a tacit admission of the defence version. [39] In Nor Badli Munawir Bin Mohamad Alias Lafti v Public Prosecutor [2024] 3 MLJ 572, the Court of Appeal had held: “[175] From our close scrutiny of the record and in particular the judgment of the learned trial judge and the learned High Court judge, we are of the considered view that failure of the prosecution to cross-examine the accused on a crucial part per se does not amount to an admission or acceptance of the accused’s testimony. We must consider the totality of the evidence and decision must be based on an examination of all the evidence presented and not evidence in isolation. Moreover, it is also apparent from the learned trial judge’s comprehensive judgment that she had directed herself on the issue of credibility of the prosecution witnesses and accepted their evidence.” [Emphasis added] [40] As a corollary, the learned High Court Judge was right in holding as follows: “[108] In my considered judgment… the court must still proceed to weigh the relative merits of the competing assertions, mindful of the standard of proof that must be discharged by the respective parties. The ordinary principles would apply on evaluating the evidence of the witness of the defence does the court believe the defence witness? If so, it must acquit. If it does not believe the witness, the court must proceed to ask itself a further question has the testimony of the witness give rise to a reasonable doubt? If the answer is in the affirmative, then the court must acquit. [109] Having evaluated the testimonies of the witnesses in this case, I was of the view that the testimonies of the accused persons have not given rise to any reasonable doubt regarding their culpability on the charges.” [41] In opting to give sworn testimonies by way of witness statements, summarily, the defence proffered by the accused persons was that they did not have access to the inside of the building as the front door of the building was locked at all material times. [42] We find that the learned High Court Judge had considered and evaluated the defence in its entirety. Upon weighing the defence and the evidence adduced before the court, the learned High Court Judge had accepted the evidence of ASP Soh (PW8) as His Lordship found no reason to disbelieve him. The learned High Court Judge preferred the testimonies of the PW8 and Mr Udiasoorian (PW13), the forensics officer, over the testimonies of the accused persons whom His Lordship found to be self-serving. [43] We find no reason to disturb the findings and evaluation made by the learned High Court Judge at the defence stage. We find that the learned Judge was right in holding that: “[91] The testimony of ASP Soh was not inherently improbable, and as such due weight ought to be accorded to his evidence. Furthermore, having observed the demeanour of ASP Soh in the course of the trial, I saw no reason to disbelieve his testimony. [92] The version of events put forth by the defence was that the hairbrushes were recovered not from the inside of the building but form the pockets of the accused persons. This was never put to Mr Udiasoorian. I was also of the view that the fact that Mr Udiasoorian had already retired by the time of trial gave greater credence to his testimony. Nothing could conceivably be gained by his giving false testimony under oath. If the defence was correct, then it must necessarily follow that Mr Udiasoorian has staged the scene of the raid by placing the hair brushes and the blue plastic bag containing the dental implements inside the building so that the police photographer could record their position as such. [92] I preferred the testimonies of PW8 and PW13 over what I viewed were self-serving testimonies from the accused persons. More than just that, I found that the evidence of the defence did not raise any reasonable doubt. The possibility that both ASP Soh and Mr Udaisoorian concocted a version of events to implicate the accused persons were in my considered judgment so infinitesimally small so as to be incapable of raising a reasonable doubt on the prosecution’s case.” [44] At the defence stage, the learned High Court Judge addressed the issue relating to Rajan a/l Gaju again specifically to the issue of the latter’s attendance who was slated to be the last witness for the defence after being offered by the prosecution at the close of the prosecution’s case. Apparently, at the time when the trial was ongoing, Rajan a/l Gaju was discharged and acquitted from a separate drug trafficking offence. Subsequent efforts to locate him came to no avail. The learned High Court Judge addressed the issue as follows: “[102] In my considered judgment, the key question determining whether an acquittal ought to be ordered is whether the non-attendance of a witness that had been offered to the defence has raised a reasonable doubt in the prosecution’s case. In PP v Asnawi Yusuf, the fact in issue was whether the accused knew that the packages contained cannabis-which went towards the mens rea for possession. The attendance of the three witnesses could establish whether or not Fakrullah did exist, and whether or not Fakrullah had asked to borrow Abdul Rahman’s Proton Iswara. Their testimony could have supported the version of events put forth by the defence, and hence their non-attendance was material to the determination of the guilt of the accused. [103] By contrast, in the present case, the objective facts established the presence of the accused persons in the house (see paragraph 34 to 39, ante). The element of physical possession of the dangerous drugs and poison could be inferred from the surrounding circumstances (see paragraph 43), as could the mental element of possession (see paragraph 49). Whether or not Rajan was called to testify would not change or negate these findings. Put another way, there was no live fact in issue that could be resolved by the attendance of Rajan. I was thus of the view that the non-attendance of Rajan would not have been capable of raising a reasonable doubt regarding the guilt of the accused persons, which was established from inferences drawn from the objective facts in this case.” [45] The approach to be taken by an appellate court when dealing with a trial court's assessment of credibility of witness is well-established by high authorities. The credibility of a witness is primarily for the trial judge. An appellate court should always be slow in disturbing such finding of fact arrived at by the judge who had audio visual advantage of the witness and we find there are no substantial and compelling reasons for disagreeing with the learned High Court Judge’s findings. Conclusion [46] In the upshot, having heard and perused the submissions of both the Appellants and the Respondent, the judgment of the learned High Court Judge and the Appeal Records, we find that the learned High Court Judge had made a clear finding of facts relating to the credibility of witnesses and ingredients of the offence. Cogent evidence was adduced and evaluated thoroughly and we find no appealable error in the judgment warranting appellate intervention. We unanimously find that the convictions are safe and the appeals by the accused persons as Appellants herein were dismissed. The convictions were therefore upheld. The sentence passed for the offence under section 9(1) of the Poisons Act 1952 (Third Charge) was also upheld [47] In regards to the death sentence meted out by the learned High Court Judge, which was mandatory at the material time and discretion for the learned High Court Judge to impose a custodial sentence was not available then, in line with the spirit manifested in the Abolition of Mandatory Death Penalty Act 2023 (Act 846) which came into effect on 4 July 2023, after having considered the background, facts and the accused persons’ mitigation, we are of the considered view that there are merits in their appeal against sentence. Their appeals against sentence for trafficking in the dangerous drugs offences were therefore allowed. [48] We accordingly set aside the death sentence for the trafficking in the dangerous drugs offences and replaced with the followings:
