No judgment or order of the High Court, or of any Judge, shall be reversed or substantially varied on appeal, nor a new trial ordered by the Federal Court, on account of any error, defect, or irregularity, whether in the decision or otherwise, not affecting the merits or the jurisdiction of the Court." [51] The combined effect of both sections is to place the burden on the party seeking retrial to satisfy the Court that there was some substantial wrong or miscarriage of justice occasioned by the trial court, which has affected the merits or the jurisdiction of the Court. For instance, in Udham Singh v Indar Kaur [1971] 2 MLJ 263, this Court ordered a new trial on the basis of a misdirection by the trial judge. The trial judge had wrongly placed the burden of proving testamentary incapacity, and it was held that the misdirection had occasioned a substantial wrong. [52] The Court of Appeal had an occasion to consider a similar issue in Tan Ah Tong v Gee Boon Kee & Ors [2006] 2 MLJ 618. In that case, no grounds of judgment were issued, for the trial judge had retired soon after the decision was delivered. The Court of Appeal declined to grant a new trial on that basis. In the words of Abdul Aziz Mohamad JCA (as he then was):- "... Where a judge does not state his reasons for arriving at his decision, the decision is not necessarily unsafe. He may have properly considered and weighed the evidence and may have arrived at the right conclusions. The decision is only unsafe in the sense that the appellate court is unable to determine, from an assessment of the judge's mental processes, that the decision is correct. But it does not follow that the course open to the appellate court to decide the appeal while doing justice is to order a new trial. It is still open to the appellate court to assess the evidence and come to a finding whether or not the evidence vindicates the decision of the trial judge. Where, in an appeal in a civil matter, as in this appeal, reasons for the decision appealed against are not available, and not obtainable, the appeal, onerous though this may be, should proceed on an examination and assessment of the evidence to enable the appellate court to decide whether the evidence justifies the decision or otherwise. It will be as if the appellate court is sitting at first instance, except that the evidence is already before it. For reasons that are obvious or can easily be imagined, a new trial is undesirable and ought not to be ordered unless there is something crucial to a just decision in the case that can be established in the new trial but cannot be established on an assessment of the evidence. The evidence being all there already, such a thing must be very rare indeed." (Emphasis ours) [53] On this point, we find the lucid remarks of Abdul Aziz Mohamed JCA (as he then was) illuminating and we endorse the passages quoted above. [54] In the instant case, the statutory requirements for a retrial have not been established by Dr Hari and Dr Namazie. We do not consider that the non-speaking judgment of the High Court, or the retirement of two panel judges at the time the Court of Appeal issued their written grounds of judgment, constitutes a substantial wrong or a miscarriage of justice that affected the merits or jurisdiction of the High Court. Further, we note that the Court of Appeal was able to, and had in fact, proceeded with the appeal and made a determination by considering all the evidence in the records of appeal available to them. There was sufficient material for the Court of Appeal to make the relevant findings and reach a decision as if it was sitting in the first instance. For these reasons, a retrial or a rehearing is not warranted. [55] We would like to add that a retrial or a rehearing should not be easily ordered. Appellate courts are advised to avoid ordering a retrial, merely on account of a non-speaking judgment by the trial judge or the absence of any finding of fact on a particular issue. In such a situation, it is the duty of the appellate court to endeavour to make its own finding of fact, based on the evidence available in the record of appeal. [56] A retrial may be unduly prejudicial to the parties and an unnecessary inconvenience to the witnesses. This is especially so in this case, where the alleged negligence occurred in September 1999, more than 17 years ago. The trial commenced in year 2007 and only concluded in year 2010, after a protracted trial spanning 23 days and involving 10 witnesses, including 7 medical professionals. A retrial would be contrary to the best interests of justice, and is in any event unwarranted in the circumstances of this case." (emphasis added) [42] In the present case, it is important to note that the Defendant was not even a party to the Previous Suit. In fact, En. Mohammad Noor Azam bin Sulaiman, whom the Plaintiff called to give evidence in the Previous Suit, was not even called as a witness in this case. There is also evidence that En. Mohammad Noor Azam bin Sulaiman had corrected his stand during the cross-examination in the Previous Suit which led to a scrutiny against the decision of the learned HCJ in the Previous Suit in this appeal, which we do not wish to elaborate on further. Equally significant is the absence of any other finding by the learned trial judge on the credibility of the witnesses independent from the findings in the Previous Suit and the strength of the documentary evidence adduced. [43] For the above reasons, we are of the opinion that the misdirection caused a substantial miscarriage of justice for both parties. Based on the surrounding facts of the present case, we are of the view that an order for a retrial is warranted in the best interest of justice. Conclusion [44] In conclusion, based on all of the above, we find that there is a clear misdirection on the part of the learned trial judge, which warrants our appellate interference. With this, we allow the Appellant's appeal and we set aside the decision of the High Court dated 05.01.2023 and we order for the case to be remitted and retried before another High Court Judge.
