the majority of the tribunal decided Malaysian limitation laws and not Indian limitations laws applied to the dispute and found that no part of the defendant's claims was time barred ('applicable limitation laws decision'); [40] In order to determine whether the learned judicial commissioner was plainly wrong in arriving at her decisions, we shall delve into our deliberations by gradually determining the following three issues in the following sequence: Issue No (i) Whether the decision of the majority of the tribunal (in applying the Malaysian limitation law (as the seat of arbitration is Kuala Lumpur - article 17.12 of the JOA) instead of the Indian limitation laws (as prescribed by article 18 of the JOA - chosen law of the parties) was a decision that exceeded the tribunal's mandate scope of submission and jurisdiction, and thereby can be set aside under s 37(1)(a)(v) [AA]. [42] The plaintiff had disputed the defendant's claims on the ground that a large part of the defendant's claims was for expenses incurred more than three years before the commencement of the arbitration (on 17 March 2017) which according to the plaintiff ought to be time barred under the Indian limitation laws (s 3 of the Indian Limitation Act 1963). [66] Faced with this dilemma, it is pertinent that this court cast much needed light to unravel this Gordian knot. Firstly, specific to arbitral awards involving time limitation issues, it is pertinent that the tests and deliberation be tied back down to the pure determination between what is procedural law and what is substantive law. This is in light of the unique or niche circumstance that time limitation can both be considered to be part of the decision-making process (as procedural law) which can be caught under s 37, and also issue of law and fact under s 42. Thus, the mere identification between a matter of decision-making process or a matter of law or fact is not entirely helpful in specific cases such as the present appeal that involves the law on time limitation. [67] Thus, if the learned JC has found that time limitation is a procedural issue, then the learned JC must also remain consistent as to find that time limitation (as a procedure) is also an integral part of the decision-making process (which can fall within the ambit of s 37). Thus, this Court of Appeal must depart (albeit very slightly) from the learned JC's ratio decidendi that the arbitral tribunal's decision on time limitation (if indeed erroneous) cannot fall within s 37 [AA]. If indeed the arbitral tribunal had erred in their interpretation of the procedural law on time limitation, then the arbitral award is 'procedurally impaired'. Thus, such procedural impairment would fall within the meaning of 'decision making process' under s 37. Therefore, the High Court is indeed clothed with sufficient jurisdiction to examine the correctness of the arbitral tribunal's decision-making process (in its determination of the time limitation issue). [68] The High Court in addressing the issue of time limitation must ask the more helpful question, that is 'whether the disputation is purely procedural or the disputation would also involve the question and examination of merits'. To this court's mind, if a particular issue or disputation would remain unchanged notwithstanding the merits of a case, then that particular issue or disputation is purely procedural. Alike in an arbitral award involving time limitation, time limitation is a purely procedural issue that is entirely disjointed and unaffected by the merits of any parties' cases. Time limitation is entirely blind to whether or not a party can prove any measure of liability against another. Even if there was any form of civil wrong proven on merits, time limitation shall still prevail if the complaint of such civil wrong was not procedurally voiced out within the prescribed limitation period. Therefore, since time limitation is blind to the substance or merits of the case, it cannot at all be said that time limitation is a matter of substantive law. In this sense, this court is in full agreement with the learned JC's finding that time limitation is a matter of procedural law (and not of substantive law). [69] A more meaningful expansion of the term 'admissibility' as propounded in the case of BBA v BAZ, would be 'procedural admissibility'. Thus, instead of embarking on a lengthy discourse on whether time limitation is a matter of admissibility or jurisdiction, it would be infinitely more helpful to determine whether time limitation is an issue of procedural admissibility or an issue of merit (or substance). Thus, this court is inclined to adopt the expanded meaning of 'procedural admissibility', as opposed to the Singaporean court's classification exercise between a matter of admissibility or jurisdiction. Thus, this court does not entirely follow the test in BBA v BAZ to classify time limitation to either be a matter of admissibility or jurisdiction. [70] The more meaningful classification would be (as this court has previously stressed) is to classify whether or not the matter was purely a procedural issue (which remains unchanged and undisturbed notwithstanding the merits of the case) or a substantive issue (which is indubitably affected by the facts, evidence, and merits of the case). And clearly, time limitation is one procedural issue that is indeed blind to the merits of the case. [71] This manner of test and classification would effectively reconcile the appropriate approach to a time limitation issue in all aspects (in the face of the differences between s 37 and the repealed s 42, and the Malaysian Federal Court's (in Jan De Nul (M) Sdn Bhd & Anor v Vincent Tan Chee Yioun & Anor [2019] 2 MLJ 413; [2019] 1 CLJ 1) classification of matters concerning the decision-making process (under s 37) and issue of law and fact which affects the parties' positions (under the repealed s 42). [72] Nonetheless, even if the High Court is clothed with the necessary jurisdiction to examine the arbitral tribunal's decision-making process (in applying time limitation), the High Court ought not to interfere with the arbitral tribunal's interpretation and application of the relevant time limitation if the arbitral tribunal's interpretation and application of time limitation is legally sound. [73] Notwithstanding the slight dissonance within the analysis and reasoning of the learned judicial commissioner, this court is still in agreement with the learned judicial commissioner's final conclusion that the issue of time limitation is purely and strictly a matter of curial or procedural law. Thus, the applicable law of time limitation shall be the governing procedural law of the seat of arbitration (that being the Malaysian law). [74] We are also in agreement with the learned judicial commissioner's finding that estoppel applies to estop the plaintiff from now denying that the proper curial law of limitation is Malaysian law considering that the plaintiff itself has relied upon the Malaysian Limitation Act 1953 in the plaintiff's own attempt to prove that its counterclaims were not barred by limitation. [75] Thus, there is no appealable errors within the final conclusion of the learned judicial commissioner's decision. Therefore, we answer issue No (i) in the negative." (emphasis added).
