that any requirement under the arbitration agreement has not been complied with, and yet proceeds with the arbitration without stating its objection to such non compliance without undue delay or, if a time limit is provided for stating that objection, within that period of time, shall be deemed to have waived its right to object.” (emphasis added) [37] As a time limit is provided for raising a challenge on the appointment of an arbitrator under s 15(1) AA 2005 and as s 7(b) AA 2005 states that if a time limit is provided for stating that objection, then if the party objecting does not do so within that period of time, then that party shall be deemed to have waived his right to object. [38] In Malaysia Airlines System Berhad v Competition Commission & Another Appeal [2022] 1 MLRA 570, the Court of Appeal provides valuable insight into the significance of the term “deemed”. It states that the word “deemed”: “[111] …is of course, a very powerful word. It brings into being a factual situation which may not in reality be there. It has the effect of creating an event or situation which ordinarily and in reality, is not even there. Lewison in The Interpretation of Contracts (5th Ed) at para 14.12 stated that where a deeming clause is used, it would usually be conclusive as to the deemed meaning or consequence” [39] It brings into reality a situation when the conditions are met. What is deemed cannot be un-deemed as by “deemed” is meant “as if it had happened.” [40] In Amanah Merchant Bank Bhd v Lim Tow Choon (Through Official Assignee) [1993] 1 MLRA 102, the Supreme Court examined a crucial clause in a guarantee that specified when a notice would “be deemed to be served.” This provision was vital because proper service of a notice of demand was necessary to establish a cause of action against the guarantor. Mohamed Dzaiddin SCJ (later CJ) interpreted the term “shall be deemed” to mean “shall be regarded as”. [41] The Court explained this by highlighting a quote from Viscount Reading CJ at paragraph 838 in R v Westminster Unions Assessment Committee; ex parte Woodward & Sons [1971] 1 KB 832 which observed that: “[15] …The intention is to treat as a fact something which has not been established as a fact - even something which can be shown not to be a fact…” [42] The Court further explained that: “[16] Although the words 'shall be deemed' in the above case was considered in the context of the statutory provisions, in our view, we can draw an analogy from this case that, in the present appeal, it is sufficient to prove service of the notice of demand by sending it through the post in an envelope addressed to the last known place of address of the defendant, and once this is established the deeming provision would apply as in the case cited above.” [43] A “deeming” provision is not a rebuttable presumption but conclusive as to the deemed meaning or consequence and the defendant was precluded from showing otherwise. [44] The fifteen (15) days deadline having lapsed long time ago, the appellant ZMSB is deemed to have waived his right to object to the appointment of the arbitrator. Whether the appellant may reserve its right to have the challenge to the appointment of the arbitrator decided in the award when it is issued [45] Here, even though the objection to the appointment was taken, it was clearly raised after a long delay and not in compliance with the strict timeframe of fifteen (15) days as provided for under s 15(1) AA 2005. [46] The appellant cannot claim the benefit of the exception to s 7 AA 2005 as there had been long and unexplained delay and more particularly the appellant had not raised the objection to the non compliance of the appointment of the arbitration under the arbitration agreement within the timeframe of fifteen (15) days as stimulated under s 15(1) AA 2005 and is therefore deemed to have waived its right to object. [47] Moreover, the appellant had proceeded with the arbitration in circumstance where if the final award is in its favour, the sting of his objection would have become irrelevant. It is for this reason that a party raising a serious objection on the appointment of an arbitrator must follow the strict procedure of s 15 AA 2005 for otherwise it would appear rather hollow an argument if it is only raised at the stage of setting aside an award only when the award is against the party raising the objection. [48] It becomes a case where what is objected to as a matter of principle fades into insignificance if finally, the award is in favour of the party objecting to the appointment of the arbitrator. [49] It is not dissimilar to a case where the party objecting has an extra quiver or bullet to shoot only if necessary, at the end of the arbitration when the award has been delivered. [50] Similarly, in Thyssen Canada Ltd v Mariana Maritime S.A. [2005] EWHC 219 (Comm), a dispute arose and both parties initially agreed during arbitration that the fire was caused by a smouldering cigarette. However, after the tribunal ruled in favour of the shipowners, Thyssen sought to overturn the award, citing new evidence that the fire was actually caused by welding in the hold. [51] The Court rejected Thyssen's challenge, holding that they could not raise objections based on new evidence after the fact, as they had accepted the cigarette explanation during arbitration. The High Court explained that: “18. It cannot be right for a party to participate in proceedings, which it believed to be irregular only to take advantage of any decision in its favour whilst keeping up its sleeve an objection to an irregularity which it will only raise in the event of an unfavourable decision” [52] In the High Court of Australia in Vakauta v Kelly [1989] HCA 44, the appellant argued that the judge’s comments during the trial indicated bias against their medical witnesses, raising concerns about a fair trial. However, the respondent countered that the appellant’s failure to object at the time constituted a waiver of the right to raise the issue later. Toohey J observed as follows: “16. There is no reason why, in authority or in principle, a litigant who is fully aware of the circumstances from which ostensible bias might be inferred, should not be capable of waiving the right later to object to the judge continuing to hear and dispose of the case…”
