where the judgment is based upon a wrong premise of fact or of law (see Perembun (M) Sdn Bhd v. Conlay Construction Sdn Bhd [2012] 1 LNS 1416; [2012] 4 MLJ 149).”. [32] In Zone Nine Sdn Bhd (previously known as GBH Ceramics Sdn Bhd) v Kien Wai Plumbing Construction [2024] MLJU 2399, I had referred to two judgments of the apex court which had enlightened on the legal principles of appellate intervention as follows: “[24] The learned counsel for the Defendant, Mr. Jeffry Wong cited the decision of the Federal Court in Gan Yook Chin & Anor v Lee Ing Chin & Ors [2004] 4 CLJ 309 for the central feature of appellate intervention, which is to determine whether the trial court had arrived at its finding correctly on the basis of the relevant law and established evidence. A decision by the trial court which was arrived at without judicial appreciation of the evidence may be set aside on appeal. In determining whether the trial judge’s appreciation of the evidence is sufficient or otherwise, the process of evaluation of the evidence by the trial judge i.e. the assessment of the evidence, the weight that was given to the evidence and the reasons for accepting or rejecting the whole or any part of the evidence, must be examined. … [26] Gan Yook Chin’s case was among the many case authorities discussed in Ng Hoo Kui & Anor v Wendy Tan Lee Peng (administratrix for the estate of Tan Ewe Kwang, deceased) & Ors [2020] 12 MLJ 67 (FC). It is settled law that an appellate court will not intervene with the decision of a trial court unless the trial court is shown to be plainly wrong in arriving at its decision. If, in arriving at the decision, it could not reasonably be explained or justified and the decision of the trial court is one which no reasonable judge could have reached, the decision is susceptible to appellate intervention. The plainly wrong test is not intended to be used by the appellate court as a means to substitute its own decision for that of the trial court on the facts [see pp 81 - 96 of the law report, especially paragraphs 62 - 78; see too, among others, Azman bin Mahmood & Anor v SJ Securities Sdn Bhd [2012] 6 MLJ 1 (FC, at paragraphs 24 and 25, p 12), Dream Property Sdn Bhd v Atlas Housing Sdn Bhd [2015] 2 MLJ 441 (FC, at paragraph 60, p 464) and MMC Oil & Gas Engineering Sdn Bhd v Tan Bock Kwee & Sons Sdn Bhd [2016] 2 MLJ 428 (CA, at paragraph 17, p 437)].”.
