… [79] Applying the legal principles in the cases of high authority as alluded to previously, it is my considered view that the Tribunal is in breach of the rules of natural justice in connection with the making of the Award as the Tribunal had, regretfully, in the course of reaching its decision, disregarded the opinion of the parties’ experts and the submissions made by the parties on the issues in respect of each of the sub-claim under Claim 1. [80] This breach is indeed serious because, had the Tribunal considered and made known its findings on each of the sub-claim, it may well be that the Tribunal would not have awarded the full amount as claimed by KPOC, despite accepting the methodology advanced by KPOC. There is no doubt in my mind that the breach of the rules of natural justice in this case is significant and has a real impact on the outcome of the arbitral proceedings. [81] Further, as per the test laid down in Jan De Nul (supra), MMHE has established that this is a deserving case for the Award to be set aside on the ground of it being in conflict with the public policy of Malaysia as the basic notions of morality and justice was violated. Upholding the Award in the circumstances of this case would be injurious to the public good or wholly offensive to the ordinary reasonable and fully informed member of the public in the light of the failure of the Tribunal to fully address the submissions of the parties in relation to each of the sub-claim under Claim 1 and to justify the quantum awarded in the sum as claimed by KPOC and the rejection of the assessment made by PB and CEH.” [64] Having engaged expert witnesses to deal with matters concerning quantum of LSSB’s claim, and, further, with the Arbitrator himself having directed the expert witnesses to provide their respective expert opinion in respect of the applicable interest rate, there is a legitimate expectation that the Arbitrator would consider the expert’s assessment in determining the applicable rate to be applied, if any, in arriving at his decision and to provide his chain of reasoning in the event he wishes to deviate from the experts’ assessment. [65] In Ahmani Sdn Bhd v Petronas Penapisan (Melaka) Sdn Bhd [2015] 11 MLJ 32, where the complaint was that there was a breach of natural justice during the arbitral proceedings or in connection with the making of the award, when the tribunal dealt with the factor of inflation without first inviting the parties to submit or address on the factor, the High Court had observed that: - “[43] In general, the parties have a right to be heard effectively on every issue that may be relevant to the resolution of the dispute. The overriding concern is fairness and the opportunity to be heard before the pronouncement or decision is made. Therefore, in keeping with that rule, the arbitral tribunal should not base its decision on matters that the parties have not submitted on. Although the arbitral tribunal is not required to select any one of the arguments or approaches articulated by the parties, it is perfectly entitled to steer a middle course through all the arguments made in order to reach its own conclusions or findings; any conclusion or finding reached nevertheless must be based on evidence placed before the arbitral tribunal. While the arbitral tribunal does not have to consult the parties on its thinking process before finalising its award, it must consult the parties where the argument by which it reaches its decision is one which does not reasonably flow from any of the already argued or submitted premises — see Soh Beng Tee & Co Ltd v Fairmount Development Pte Ltd [2007] SGCA 28; [2007] 3 SLR (R) 86, discussed in The Government of India v Cairns Energy & Anor [2014] 9 MLJ 149. Where the arbitral tribunal has done so, as is alleged here, then a case of a breach of natural justice is made out. … [49] With respect, this is where the arbitral tribunal has exceeded its jurisdiction. Where the arbitral tribunal wants to do more, which it obviously wanted in this case, including introducing the matter or element of inflation, as well as offer its views as to the value of that factor of inflation; the arbitral tribunal was obliged to go back to the parties. There, it may sound out its concerns, bring up this matter of inflation and even offer its view as to the value of the inflation as well as the source or evidence of that value and then, invite views or submissions of the parties on the matter. The arbitral tribunal is obliged to do so because it takes its jurisdiction from the submission of the parties. Although the parties may have submitted the matter of the counterclaim for the arbitral tribunal’s determination, it was only within the terms as found in the points of claim, defence etc. The evidence was entirely of the parties’ making and responsibility; not the arbitral tribunal’s. The arbitral tribunal does not have inherent or residual powers or jurisdiction in these matters which are almost entirely dictated by the parties. [50] Hence, the arbitral tribunal ought to have invited the parties to address or make further submissions first before it proceeded to consider and to make this particular item of award. It is this failure that gives merit to Ahmani’s complaint that the award contains a decision on a matter beyond the scope of the submission to arbitration under sub-para 37(1)(a) (v).” [66] Therefore, I accept LSSB’s contention that the Arbitrator’s approach in respect of the 5% rate was arbitrary and could not have been reasonably anticipated. The reasoning cannot be deduced due to the absence of such reasoning in the Award, as well as from the arguments and evidence presented during the Arbitration. Had the parties been alerted that the Arbitrator intended to proceed as he did, or invited parties’ views, LSSB could possibly have persuaded the Arbitrator to reach a result in LSSB’s favour, or if not a result less adverse to LSSB and, thus, will have a material impact to the Arbitrator’s determination or outcome of the Arbitration. [67] Accordingly, I find that LSSB has successfully established, on this ground (in respect of the award of interest at the rate of 5% per annum on the 1st Tranche), that the Award is in conflict with the public policy of Malaysia where a breach of the rules of natural justice occurred during the Arbitration. Other grounds relied by LSSB [68] As I have allowed the application to set aside the Award solely on the first ground, I do not wish to discuss each of the other grounds individually and separately. Instead, I wish to canvass these other following grounds and issues collectively: -
