22.2. If the adjudicator fails to address the question referred to him because he has taken an erroneously restrictive view of his jurisdiction (and has, for example, failed even to consider the defence to the claim or some fundamental element of it), then that may make his decision unenforceable, either on grounds of jurisdiction or natural justice: see Ballast, Broadwell, and Thermal Energy.”(emphasis added) [69] However the confusion here had sprung from the conflation in the use of the word “jurisdiction”. The Federal Court had in View Esteem (supra) approved of the different senses in which the word “jurisdiction” had been used as in the core or original jurisdiction as opposed to competence and contingent jurisdiction in Terminal Perintis Sdn Bhd v Tan Ngee Hong Construction Sdn Bhd and another case [2017] MLJU 242 as follows: “[16] The term 'jurisdiction' under the CIPAA is not used in the administrative or public law sense but in relation to matters within the scope of the CIPAA. On this point, in Terminal Perintis Sdn Bhd v Tan Ngee Hong Construction Sdn Bhd and another case [2017] MLJU 242 Lee Swee Seng J observed as follows (at para [70]): In the application of our CIPAA, we are free from the shackles of the language of administrative law and judicial review. The word 'jurisdiction' is used in s 15(d) as in the adjudicator having acted in 'excess of his jurisdiction' as a ground for setting aside an adjudication decision. It is also used in s 27(1) with respect to an adjudicator's jurisdiction being limited to the matters raised in the payment claim and the payment response. Then there is a reference to it in s 27(2) with respect to extending his 28 jurisdiction by way of agreement in writing to deal with matters not specifically raised in the payment claim and payment response. Finally there is the reference to a 'jurisdictional' challenge, which when raised, does not prevent the adjudicator from proceeding and completing the adjudication without prejudice to the rights of any party to set it aside under s 15 or to oppose its enforcement under s 28 ... Issues as to whether there is a valid cause of action, does not go towards jurisdiction but rather to the merits of the claim ... [17] The learned judge also made note of the various types of jurisdictional complaints within the CIPAA which may be categorised as core jurisdiction, competence jurisdiction and contingent jurisdiction. The common feature in all of them is the presupposition that the CIPAA applies to determine if the adjudicator had kept within his jurisdiction." [70] A core or original jurisdiction issue would be one where the question is whether the CIPAA would apply to the type and nature of the contract where the applicability or non-applicability as the case may be of the CIPAA with respect to section 2 and 3 of the Act is concerned. [71] For instance if it is raised, as in this case, that the contract is one that is partly in writing and partly oral and as such it is outside the scope of the applicability of section 2 of the CIPAA. [72] In such a case an Adjudicator is at liberty to proceed under section 27(3) of the CIPAA as if he has jurisdiction and to leave the issue of core or original jurisdiction to the Court in a setting aside application or in opposing an enforcement application. Section 27(3) of the CIPAA expressly empowered the Adjudicator to so proceed as follows: 29 “(3) Notwithstanding a jurisdictional challenge, the adjudicator may in his discretion proceed and complete the adjudication proceedings without prejudice to the rights of any party to apply to set aside the adjudication decision under section 15 or to oppose the application to enforce the adjudication decision under subsection 28(1)." [73] In a case of contingent jurisdiction, an Adjudicator having a core or original jurisdiction to adjudicate the dispute, would have jurisdiction to decide on the dispute before him if the matter is raised in compliance with the conditions in the CIPAA. For example his jurisdiction is over matters raised in the Payment Claim and Payment Response as stated in section 27(1) of the CIPAA. The Federal Court had also held in View Esteem (supra) that even though for example, a defence has not been raised in the Payment Response but raised for the first time in the Adjudication Response, the Adjudicator must still consider it and not decline jurisdiction for to do so would be to unduly restrict one’s jurisdiction. [74] I understand that learned counsel for the Employer is challenging the core or original jurisdiction of the Adjudicator in that he has no jurisdiction to adjudicate on a construction contract that is not wholly in writing but one which had been varied by an oral contract. Learned counsel had cited the case of YTK Engineering Services Sdn Bhd v Towards Green Sdn Bhd & Other Cases [2017] 1 LNS 601 as follows: “[59] However here we are talking about his core jurisdiction as in whether CIPAA confers jurisdiction on an Adjudicator with respect to the type of "construction contract" that falls within the ambit and powers of an Adjudicator under the scheme of statutory adjudication. Thus a construction contract for the construction of a house by a natural person for the buyer's 30 occupation and a non-payment under it would not be a matter that is covered under CIPAA because of its non-application section under section 3 CIPAA. Likewise a construction contract for construction work carried out wholly outside the territory of Malaysia. So too would be a shipping contract or a mining contract which does not fall within the meaning of "construction work" under section 4 and hence not a "construction contract" under section 2 and 4 of CIPAA. [60] An Adjudicator cannot adjudicate a Payment Claim made under any contract but only one made under a "construction contract" as set out under the "Application" section in section 2 and as defined in section 4 and as one not coming within the non-application provision of section 3. [61] Where CIPAA does not confer jurisdiction on the Adjudicator to adjudicate a Payment Claim because it does not fall within the meaning of "construction contract" then the Adjudicator cannot erroneously assume jurisdiction. This is because it relates to his core jurisdiction which Parliament under CIPAA has not conferred jurisdiction on him. [62] Where an Adjudicator makes an error with respect to his core jurisdiction, this Court is at liberty to set the Decision aside on ground that he had no jurisdiction to adjudicate and hence exceeded his jurisdiction by proceeding to adjudicate when he should not have.” (emphasis added) [75] Here the issue of whether the contract is not fully in writing but altered with respect to payment in an oral agreement, when argued from the point of view of core or original jurisdiction would mean this: does the CIPAA 31 under section 2 apply to a construction contract in writing when the contract has been altered by an oral agreement on terms of payment? [76] This issue had been raised in a application brought by the Employer’s previous solicitors on 4.1.2018. Euroland had filed an originating summons in WA-24C-5-01/2018 for, inter alia, a declaration that any disputes arising between Euroland and Tack Yap in relation to the Project do not fall within the ambit and jurisdiction of the CIPAA in that the construction contract was not one in writing as part of the Contract was an oral agreement on the terms of payment with respect to Euroland paying only 80% of each Interim Certificate. [77] There was also an interlocutory application sought before this Court to injunct the Adjudicator from proceeding on ground that the contract in question was partly in writing and partly oral and as such it falls outside the scope of section 2 of the CIPAA and with that the Adjudicator had no jurisdiction to proceed to adjudicate the dispute. The application for an injunction was not proceeded with as parties could agree to the Court granting an order for extension of time for the respective parties to serve their Adjudication Response and Adjudication Reply and in the meanwhile this Court had dismissed the declarative prayers of Euroland. [78] It is for the Adjudicator to make his finding of fact as to whether there was such an oral contract which in this case has the effect of varying the written terms of the contract in writing in the Letter of Award which had also referred to the Tender Documents submitted which included the Bill of Quantities and the rates and pricing duly filled up. The Adjudicator in proceeding with the Adjudication was merely following the directions of the High Court and that surely cannot be a breach of natural justice. 32 [79] It cannot be a case where the moment an oral contract is raised then the Adjudicator must decline jurisdiction unless of course both the Claimant and Respondent in the Adjudication had agreed that the whole of the contract is oral. [80] If that were so then it is very easy to defeat Adjudication by merely asserting that the contract was an oral contract or that it was partly in writing and partly oral and then the Adjudicator would have no jurisdiction to proceed with the Adjudication. Precisely because of this that Parliament in its wisdom enacted section 27(3) of the CIPAA to grant liberty to the Adjudicator to proceed as if he had jurisdiction and to deliver his Decision, with that Decision being liable to be set aside for excess of jurisdiction in the High Court under section 15(d) of the CIPAA. [81] Parliament appreciates that some issues on jurisdiction with respect to core or original jurisdiction can be deep waters beyond the depths of some Adjudicators who may not be legally trained but whose expertise are drawn from other professional fields such as Quantity Surveying, Architectural or Engineering. [82] I see nothing wrong and everything proper for the Adjudicator to proceed under section 27(3) of the CIPAA and leave the matter of jurisdiction to be argued in this Court in a setting aside application. [83] To be fair to the Adjudicator he had given his reasons at pages 17-20 of his Decision on why he had rejected the argument of the Employer that there was an oral agreement to vary the written terms of the construction contract. The Adjudicator was unimpressed with the fact that Euroland through their Chief Operating Officer, Mr KH Tong, could not recall the exact location(s) and discussion(s), if at all, which led to the Oral Agreement. He expressed his bewilderment over the fact that if there had 33 been an Oral Agreement as alleged, then surely there would be some contemporaneous response to the multiple reminders for the short payments for there were no less than 7 Interim Certificates issued by the Architect. He found on the balance of probabilities that the so-called Oral Agreement did not exist. [84] There is clearly and certainly no denial of natural justice here but a most natural course to take in the interest of justice where the Decision of interim finality may be considered from the point of view of whether he had unduly restricted his jurisdiction in so deciding. Whether there was a denial of natural justice when en-route to dismissing the Employer’s set off, the Adjudicator had decided on the validity of the termination by the Main Contractor [85] Learned counsel for Euroland submitted that when the Adjudicator decided on the validity of the termination by Tack Yap, he went on a frolic of his own as the parties had not submitted on it. It was argued that he should have given the parties an opportunity to comment on what he had minded to decide with respect to the issue of termination. [86] The case of Cantillon Ltd v Urvasco Ltd [2008] 117 ConLR 1 was cited as authority for the above proposition. [87] The Employer’s assertion of a denial of natural justice on the above ground is misconceived. To begin with it was the Employer who had raised as their defence in the Payment Response served the wrongful termination by the Main Contractor. The Adjudicator stated in paragraph 8 and page 8 of his Decision that the Employer had alleged that even if there was underpayment (which the Employer denied), that did not constitute a 34 repudiatory breach entitling the Main Contractor to terminate the Contract and the Main Contractor wrongfully terminated the Contract. [88] Therefore as the issue of wrongful termination by the Main Contractor was raised by the Employer themselves in the Payment Response, the Adjudicator must of necessity consider the issue for otherwise he would be in breach of natural justice. [89] The Employer as Respondent in the Adjudication had further reiterated and repeated this in their Adjudication Response as pointed out at paragraph 11 at page 13 by the Adjudicator in his Decision wherein it was summarized that the Employer asserted that they had fulfilled their obligations in accordance with the Oral Agreement and that the termination by Tack Yap as the Claimant in the Adjudication was wrongful. It was further stated that the Employer accepted the alleged wrongful termination as repudiation of the Contract by the Main Contractor. [90] In fact the Employer had premised their set-offs precisely on the allegation of the Main Contractor having terminated the Contract unlawfully. At paragraph 9 of page 8 of the Decision the Adjudicator had stated that due to the termination of the Contract by the Main Contractor, the Employer had to engage a replacement contractor to complete the Works and that they would hold the Main Contractor liable for the costs and expenses associated with the engagement. [91] It was in that context that the Adjudicator had to consider the validity of the termination by the Main Contractor for underpayment of the Interim Certificates. The Adjudicator had to consider the issue of the validity of the termination raised by the Employer as without deciding on that he would not be able to decide on whether the Employer’s defence by way of a set-off should be allowed. 35 [92] Whether or not further submissions would be required on the issue of termination is a matter within the discretion of the Adjudicator under section 25(a) of the CIPAA. If a matter is a natural consequence arising from his finding of fact and if he is clear on the law, there is no need for him to ask for further submissions from the parties. [93] It is for him under section 25(a) of the CIPAA to establish the procedures in conducting the adjudication proceedings including limiting the submission of documents by the parties. Where parties had the opportunity to submit but failed to, they cannot be heard to be complaining of a denial of natural justice. Even the refusal to accept further submissions are not grounds for arguing a denial of natural justice. [94] In Tidalmarine Engineering Sdn Bhd v Conlay Construction Sdn Bhd and another appeal [2017] MLJU 738 at paragraph 42 it was held that there was no basis for arguing that there was a breach of natural justice merely because the Adjudicator had not allowed the parties to file their written submissions on the issues raised and in particular, on the jurisdictional challenge taken. [95] Likewise in TYL Land and Development Sdn Bhd v SIS Integrated Sdn Bhd and another case [2018] MLJU 217 it was observed as follows: “[106] The Adjudicator further found that all the submissions before him are clear for him to make a decision as stated in paragraph 39 of the Decision. Thus, having considered the Respondent’s solicitors request and having found that there is no necessity for further submissions, the Adjudicator could not be said to have committed any breach of natural justice. [107] The Court would be loathed to interfere with the discretion of the Adjudicator in deciding whether or not to allow further 36 documents to be served unless the procedure adopted is manifestly unfair or prejudicial to one party.” (emphasis added) [96] The issue of the validity of the termination cannot be divorced from the set-off claimed by the Employer with respect to the costs and expenses incurred by them in engaging a rescue contractor to complete the unfinished Works. It cannot be gainsaid that if the termination by the Main Contractor is unlawful then the Employer would be entitled to the set-off raised, subject always to proof. Conversely if the termination by the Main Contractor is lawful then the Employer would not be able to claim for the set-odd raised in the costs and expenses incurred in so engaging a rescue contractor to finish the Works. [97] I find no denial of natural justice in the way the Adjudicator had gone about deciding on the issue of the validity of the termination raised by the Employer as Respondent in the Adjudication in their Payment Response and Adjudication Response as follows at pages 24-25 of the Decision: “4.2. Issue 4.2: Is the Respondent’s allegation that even if there was underpayment that it would not constitute a repudiatory breach entitling Claimant to terminate the Contract and that Claimant wrongfully terminated the Contract valid? If so, are Respondent’s claims for costs due to engaging new contractor valid? ….. b. Section 40 of The Malaysian Law of Contract (1950) states: “When a party to a contract has refused to perform, or disabled himself from performing his promise in its entirety, the promise may put an end to the contract, unless he has signified by words or conduct, his acquiescence in its continuances.” 37 The “promise” in this case is the obligation of the Respondent to pay the Claimant, and at face value it would seem that the claimant was justified in termination, as the Respondent had not fulfilled his promise to pay. c. However, it is an established principle that not every breach of promise in a contract will give rise to a right to terminate or rescind a contract. The Malaysian Court of Appeal has addressed this point in Kemuning Setia Sdn Bhd vs. Tan Kok Siang where reference was made to Visu Sinnadurai on “The Law of Contract” which states that the guideline is “whether the breach is of sufficient gravity to allow the other party to rescind the contract” and further in the Court of Appeal’s decision (quoted in Kamuning Setia vs. Tan Kok Siang) in Ching Yik Development Sdn Bhd v Setapak Heights Development Sdn Bhd [1996] 3 MLJ 675 which held that: “Now, in every contract, be it for the sale of land or any other commodity, there are, generally speaking, some terms that are of fundamental importance and others of less or minor importance. The law creates the distinction for the purpose of determining the kind of remedy that is to be made available to an innocent party, i.e. the party who is not guilty of the breach. Where the term that has been flouted is fundamental to the contract, the innocent party is entitled to treat himself as being discharged from further obligations under it. But where the obligation that has been breached is only subsidiary or minor in nature, the innocent party may not treat himself as being free of 38 his obligations under the contract, although he may sue and recover damages for the non-performance of the subsidiary term.” d. The question that needs to be answered is whether the breach of promise in this matter, the non payment of more than 20% of the Certified Claim, was “subsidiary or minor” in nature. I find that the non-payment of such a large proportion of the claims cannot be regarded as subsidiary or minor, and I determine that the Claimant’s termination of contract was valid. As such, I determine that Claimant has no liability for the costs and expenses incurred by Respondent arising from this termination.” (emphasis added) [98] Even if there had been a breach of natural justice, for which this Court had found none, it is one that falls within the exception stated in the case of Herbosh-Kiere Marine Contractors Ltd v. Dover Harbour Board [2012] 140 Con LR 47 in page 110 where it was held that: "[32]...Whilst the principle which he puts forward is unchallengeable, and although it could be said that the adjudicator has arguably gone wrong in fact or in law in assessing the financial entitlement as he did, it is not that which is the subject of legitimate criticism. What he can be criticized for is deciding something not only on a basis which was not argued in the adjudication proceedings but also without giving either party the opportunity to address the point. ... 39 [33] In essence, and doubtless for what he believed were good and sensible reasons, the adjudicator has gone off "on a frolic of his own" in using a method of assessment which neither party argued and which he did not put to the parties. In some cases, this may not be sufficient to prevent enforcement of the decision where the "frolic" makes no material difference to the outcome of the decision. Thus, an adjudicator who refers to a legal authority which neither party relied upon, may have his or her decision enforced nonetheless if the application of that legal authority obviously makes no difference to the outcome. The breach of the natural justice has to be material. Here, for the reasons indicated above, the breach is material and has or has apparently led to a very substantial financial difference in favour of HKM but necessarily against the interests of DHB.” (emphasis added) [99] There was thus nothing wrong on the Adjudicator referring to the propositions of law en-route to and in support of the finding of mixed fact and law that the termination of the Contract by Tack Yap as the Main Contractor was lawful and valid on the circumstances of the case. [100] I am reminded of the dicta in Cantillon Ltd v Urvasco Ltd [2008] 117 ConLR 1 where it was observed as follows: "[67] .....As the authorities established that the responding party can put forward any arguable defence in adjudication, ......it must follow that the adjudicator can rule not only on that defence but also upon the ramifications of the defence to the extent that it is successful in so far as it impacts upon the fundamental dispute." (emphasis added) 40 [101] Once the defence of set-offs is raised and in this case in the context of additional costs and expenses incurred on the engaging of a rescue contractor to finish the Works, the ramifications of the defence raised by the Employer as Respondent in the Adjudication in both their Payment Response and Adjudication Response, are such that the Adjudicator cannot afford not to consider it for otherwise he would be in breach of natural justice. Whether the Adjudicator had exceeded his jurisdiction in that the construction contract was not one made in writing as part of the Contract was an oral contract on the terms of payment [102] It was argued that the Adjudicator had no jurisdiction as the construction contract in question was not one “made in writing” in that part of the Contract was oral. [103] The Adjudicator had given his reasons for rejecting the argument by Euroland that there was an oral contract with respect to the Payment Terms in that the Employer was only contractually obliged to pay 80% of the Interim Claims certified for the Progress Claims on the Work done. [104] I would not disturb that finding of fact based on cogent reasonings as set out in pages 17-20 of his Decision. [105] As such the question of a lack of jurisdiction or having acted in excess of his jurisdiction, does not arise. [106] Assuming for a moment that there was indeed an oral term in a construction contract in writing, does it mean then that the Adjudicator would have no jurisdiction? I have set out the reasons for rejecting that argument in Euroland & Development Sdn Bhd v Tack Yap 41 Construction (M) Sdn Bhd [2018] MLJU 861. I shall not repeat what had been stated there but shall only add the following: Section 2 of the CIPAA reads: “This Act applied to every construction contract made in writing relating to construction work carried out wholly or partly within the territory of Malaysia including a construction contract entered into by the Government.” [107] It is obvious that the Legislator did not say that the “construction contract” must be wholly in writing. It is not unusual in a construction contract for some terms to be varied orally as parties proceed along the performance of the Contract. It may be a term on Variation where it is oral and perhaps there may or may not be Minutes on the said Variation requested by the Employer or the Superintending Officer or the Project Director. There might be a variation with respect to additional works or omission of works or for purchase of materials by the Employer or that there should be no need for a Bankers Guarantee as contractual required in writing of the Main Contractor but that a retention sum should be deducted from every Interim Certification of the Progress Claims. It may even be a case of the Main Contractor requesting for direct payment to the Subcontractor from the Employer or that the Employer had agreed to materials of a similar brand to be used in substitution to that which had been contractually agreed. [108] The permutations can be varied and to allow a construction contract to be excluded from Adjudication under the CIPAA on a mere oral variation of the construction contract in writing would be to encourage a Non-Paying Party to skirt Adjudication and indeed to immunize themselves from 42 Adjudication on such a flimsy ground as that parties had agreed to an oral variation of the written contract. [109] The KLRCA CIPAA Circular 03 (now read as the AIAC CIPAA Circular 03) clarified the meaning of a “construction contract made in writing” as follows: “CONSTRUCTION CONTRACT IN WRITING”
