days after receipt of a written notice from the S.O. requiring compliance with an instruction the contractor does not comply therewith, then the S.O. without prejudice to any other rights or remedies available to the Government under the Contract may employ and pay other persons to execute any work whatsoever which may be necessary to give effect to such instruction and all costs incurred in connection with such employment shall be recoverable from the Contractor by the Government or the S.O. on its behalf as a debt or maybe deducted by the Government from any monies due or to become due to the Contractor under this Contract." [34] After the consent judgment recorded by the parties for the Arbitrator to give her reasons for the said finding, the Arbitrator maintained the reason as stated in paragraph 2.5 of the Supplementary Award that: 38 " By conduct, both Parties had accepted Retention Sum as a mode to allocate funds for rectification works as per the normal practice in construction contracts. As per F/A Para 2.35, the Respondent had retained RM21,154.39 as Retention Sum under Employer's Payment Advice dated 29 March 2012 as the cost of the Claimant's liability for outstanding rectification of defects." [35] Though the word limit was not used by the Arbitrator, clearly the Arbitrator was limiting the Respondent's counterclaim in the Arbitration to the Retention Sum. I find merits in the submission of learned counsel for the Respondent Sime Darby that the issue of whether the costs of rectification works that can be claimed is limited to the amount of the Retention Sum, was not an issue which arose in the pleadings or in the course of the Arbitration proceedings. The parties were not alerted to this issue by the Arbitrator and were not invited by the Arbitrator to submit on this issue. 39 [36] Learned counsel for Sime Darby further submitted that during the course of the Arbitration proceedings, the contention that parties had agreed to limit the rectification costs to the Retention Sum was never put to Sime Darby's witnesses by the Claimant's counsel during cross-examination. [37] I can appreciate the Respondent's counsel argument that when there is an express clause in Clause 5(b) of the Conditions of Contract that unambiguously provided for all costs to be recoverable from the Claimant without any provisions limiting such sums to be recovered, the Arbitrator cannot assume that parties had accepted otherwise in contradistinction to the pleadings and to the conduct of the parties' case. [38] It was not the Claimant's case that the parties had expressly agreed by conduct to limit the rectification costs to the Retention Sum; indeed their position was based solely on the argument that the appointment of Muzqi (third party contractor) was unnecessary and contractually unjustified as the Claimant had completed all works and had rectified all defects. [39] The proper course for the Arbitrator to take would be to invite the parties to submit on this new issue that had irked her on whether parties by 40 their conduct accepted the Retention Sum as the amount to be forfeited to the Respondent in full payment for whatever might be the costs of the rectification works. However this was not done and so the Arbitrator went on to decide on an issue not at play and not pleaded and in that pejorative sense, an 'invented issue' and thus was in breach of natural justice in not allowing the parties to be heard on this new issue. [40] As the Arbitrator had ordered that this Retention Sum of RM21,154.39 be set off from the Final Certificate Amount of RM338,666.39, it is a decision that taints the whole Award such that the whole Award has to be set aside. It is not possible to extricate the part of the Award not affected from the part that is affected because one sum is extricably intertwined with the other such that one would affect the other. [41] It is not for this Court to second-guess what her decision would have been if she had heard the parties on this issue of the Retention Sum being all that the Respondent could claim for rectification works. It is sufficient to be set aside if this Court finds that the Respondent had been prejudiced as a result of not having the opportunity to address the Arbitrator on this new issue not at play and certainly not in the pleadings. So long as it is 41 reasonably arguable that the Arbitrator's decision might have been different had she had the benefit of submission from both parties, that would be enough for the Court to set aside the Award on ground of breach of natural justice. [42] It may further be added that if the Arbitrator had wanted to rely on her knowledge of what she understood to be the usual practice in construction contracts, then she should inform the parties about it and invite them to challenge such an understanding of usual practice. I am not unaware that an Arbitral tribunal shall have the power under section 21(3)(b) AA to draw on its own knowledge and expertise in deciding on a dispute before it. Likewise an Arbitrator shall decide based on the usual practice in the building industry as provided for under section 30(5) AA which reads: “(5) The arbitral tribunal shall, in all cases, decide in accordance with the terms of the agreement and shall take into account the usages of the trade applicable to the transaction.” I am also mindful of section 26(5) AA that reads: 42 "Any expert report or evidentiary document on which the arbitral tribunal may rely in making its decision shall be communicated to the parties.” [43] However that is no liberty nor license to decide on an issue dehors the pleadings and what is submitted for decision for an Arbitrator's jurisdiction is derived by consent of the parties in the agreement to submit to Arbitration as may be gathered from the pleadings and submissions of the parties. [44] I would follow the approach taken by Justice Wong Kian Kheong JC in Sigur Ros Sdn Bhd v Master Mulia Sdn Bhd [2015] 1 LNS 1094 where his Lordship observed as follows: "49. Section 21(3)(b) AA allows the Arbitrator to “draw on its own knowledge and expertise”. According to s 26(5) AA, any expert report or document relied on by a Tribunal in making its decision, should be communicated to parties. I am of the opinion that in view of ss 20, 26(5), 37(1)(b)(ii) and 37(2)(b) AA, if a Tribunal draws on its own expertise, experience and knowledge pursuant to s 21(3)(b) AA, the Tribunal should have informed the parties of 43 such a matter and invite parties to adduce evidence (or expert evidence) and submit on such a matter. I rely on Ackner LJ’s (as he then was) judgment in the English Court of Appeal case of Interbulk Ltd v Aiden Shipping Co Ltd, The Vimeira [1984] 2 Lloyd’s Rep 66, at 76, as follows – “If an arbitrator considers that parties or their experts have missed the real point – a dangerous assumption to make, particularly where, as in this case, the parties were represented by very experienced Counsel and solicitors – then it is not only a matter of obvious prudence, but the arbitrator is obliged, in common fairness or, as it is sometimes described, as a matter of natural justice, to put the point to them so that they have an opportunity of dealing with it.” (emphasis added). [45] Having found that there was a breach of the rules of natural justice under section 37(2)(b)(i) and (ii) AA that had occurred during the Arbitral proceedings and in connection with the making of the Award, this Court would be constrained to set aside the whole Award. Surely in the 44 circumstance the Respondent cannot be expected to pay the Claimant the final sum awarded in the Award that had allowed the sum for rectification works arrived at in breach of natural justice to be deducted from the Final Certificate Amount yielding the sum of RM282,512.00. Whether the Award deals with a dispute not contemplated by or not falling within the terms of the submission to Arbitration when the Arbitrator decided that by conduct, the parties have accepted that the Respondent's claim for rectification works is the sum retained as Retention Sum under the contract [46] The Court of Appeal in Kerajaan Malaysia v Perwira Bintang Holdings Sdn Bhd [2015] 1 CLJ 617 had explained how an Arbitrator might fall into the jurisdictional error as in acting in excess of his jurisdiction as envisaged in section 37(1)(a)(iv) AA as follows: “Finding Of New Difference” By The High Court [22] The learned High Court Judge considered the background facts in some detail. Her Ladyship also evaluated the issues formulated by the arbitrator, as agreed and modified by both parties. Her Ladyship considered the detailed finding of the 45 arbitrator, which was quoted in extenso, but concluded that the arbitrator had decided on a dispute which was not contemplated by, or not falling within the terms of the submission to arbitration. This is an area of arbitration law which allows the court to set aside an award on the ground that an arbitrator had decided on a “new difference” which is irrelevant to the claim, the “new difference” being understood as a new dispute not contemplated by or not falling within the terms of the arbitration submission. The underlying rationale for this rule rests on the consensual nature of arbitration. Parties are not compelled to resort to arbitration contractually, but if they provide for it and refer their dispute to arbitration, the mandate of the arbitrator must be limited to the terms defined by the parties for him to exercise his jurisdiction. If the arbitrator strays from the confines of this mandate, he will be acting in excess of his jurisdiction, even though he may have the initial and primary jurisdiction to arbitrate between the parties. This rationale is stated succinctly by the Court of Appeal, Singapore in PT Prima International Development v. Kempinski Hotel SA & Other Appeals [2012] SGCA 35: 46 An arbitral tribunal has no jurisdiction to resolve disputes which have not been referred to it in the submission to arbitration. Simply put, a party cannot raise a new dispute in an arbitration without the consent of the other party. These propositions flow inexorably from the consensual nature of arbitration. [23] This case was cited by Her Ladyship, together with several other decisions of the Singapore Courts, such as PT Asuransi Jasa Indonesia (Persero) v. Dexia Bank SA [2007] 1 SLR (R) 597, CRW Joint Operation v. PT Perusahaan Gas Negara [2011] 4 SLR 305 and Sui Southern Gas Co Ltd v. Habibullah Coastal Power Co (Pte) Ltd [2010] 3 SLR 1. [24] These persuasive cases, and others, that have been addressed by our courts lay down one basic principle – an arbitrator must decide the dispute according to the scope of the arbitration and he cannot decide the dispute on issues that have not been raised or addressed by the parties. This basic principle arose in the High Court case of Government of the Lao 47 People’s Democratic Republic v. Thai-Lao Lignite Co Ltd (“TLL”) A Thai Company & Anor [2013] 1 LNS 83, where Lee Swee Seng JC (as he then was) said: Whilst it is generally stated that under the Model Law regime as reflected in the AA 2005, there is a palpable shift towards non-interference in international arbitration award especially on issues of error of law so called, yet where jurisdiction is concerned, the Model Law does recognize and respect court’s interference where arbitrators have acted outside their jurisdiction and this principle is reflected in ss. 37(1)(a)(iv) and (v) of the AA 2005 ... (at pg. 18 of the Judgment) [25] Lee Swee Seng, JC expressly referred to and adopted the reasoning shown in the Singapore authorities, namely PT Asuransi Jasa Indonesia (Persero) v. Dexia Bank SA, supra, and CRW Joint Operation v. PT Perusahaan Gas Negara, supra. 48 [26] A differently constituted panel of this court agreed with the High Court’s decision and dismissed the appeal.” (emphasis added). [46] Here, while it was within the parties’ submission to arbitration that the Arbitrator should decide on whether the Respondent was entitled to the sum of RM 246,978.00 being the costs of rectification works or such other amount as may be assessed by the Arbitrator or not at all, it certainly was not within the submission and contemplation of the parties that the Arbitrator would be deciding on whether there was consent between the parties by conduct that the Respondent had accepted the Retention Sum as the amount they are entitled to in the event that rectification works have to be done. What is even more perplexing is that in the very next breath the Arbitrator had held that this is so "although not provided for in the Contract for this matter." [47] The Arbitrator had earlier set out Clause 5(b) which is the provision in the Contract for this matter. [48] Here we are not quibbling or questioning the finding of fact of the Arbitrator but we are dealing with a far more basic issue which is whether 49 the parties had agreed in their submission to Arbitration that the Arbitrator should be deciding on this very matter of whether there was such a conduct of the parties on the acceptance of the Retention Sum as all that the Respondent could claim in the event of rectification works that are needed to be done. [49] The answer is a resounding 'no'!, being not a matter pleaded or at play in the Arbitral proceedings or in the submission filed by both parties. [50] That being the case, the Award has ventured into a dispute not contemplated by or not falling within the terms of the submission to arbitration and as such the consequence is that the whole of the Award has to be set aside. [51] As I had decided for the Respondent Sime Darby under the setting aside application under section 37 AA, there is no need then to continue to consider the Respondent's application under section 42 AA. 50 Pronouncement [52] For all the reasons above, I allowed the application to set aside the Arbitration Award under section 37(1)(a)(iv) and 37(1)(b)(ii) and 37(2)(b)(i) and (ii) AA and accordingly dismissed the application to enforce the Award. After hearing the parties I made no order as to costs. Dated 31 January 2017. - signed - Y.A.
