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).” [36] What the Second Adjudicator did in exercising his discretion to proceed even in the light of a jurisdictional challenge is perfectly permitted for under section 27(3) of the CIPAA. An Adjudicator when faced with such 19 a jurisdictional challenge may proceed, with or without giving any reasons, for being convinced that he has jurisdiction to hear the dispute. [37] Even when he has doubt he is still perfectly permitted to proceed to hear the parties and deliver his Adjudication Decision and it is for the party against whom the Decision is made to mount a challenge under section 15 of the CIPAA or to oppose the enforcement of the Decision under section 28(1) of the CIPAA. [38] By deciding to proceed to hear the dispute an Adjudicator need not fear that he is violating the principle of kompetenz – kompetenz, which is a jurisprudential doctrine whereby a tribunal may have competence, or jurisdiction, to rule as to the extent of its own competence on an issue before it. Whether or not an Adjudicator gave reasons for agreeing that he had jurisdiction, that does not fetter the High Court to consider the issue of a jurisdictional challenge afresh in a section 15 application for setting aside or section 28 application for enforcement of an Adjudication Decision or in an application for a declaration that the Adjudicator had no jurisdiction to begin with. [39] Likewise if an Adjudicator declines or rejects his appointment on ground that he has no jurisdiction to hear the dispute, as was done by the 20 First Adjudicator, the Claimant may still proceed by asking the Director of KLRCA to appoint a new Arbitrator as happened in this case. [40] Granted the expression of a “jurisdictional challenge” may be understood in at least 3 different senses as was held in Terminal Perintis Sdn Bhd v Tan Ngee Hong Construction and another case [2017] MLJU 242 which was cited with approval by the Federal Court in View Esteem Sdn Bhd v Bina Puri Holdings Berhad [2018] 2 MLJ 22 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 21 there is a reference to it in s 27(2) with respect to extending his 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. [18] We are in agreement with the contention of the appellant that the error in the judgment of the Court of Appeal is the failure to recognise that the jurisdictional complaint in the present case is that the CIPAA did not apply at all because of s 41, and not an ‘excess of jurisdiction’ 22 under s 15, on the basis that CIPAA applied. It is what is termed as an absolute lack of jurisdiction that may be taken up at any time. On this point, the Singapore High Court case of Chip Hup Hup Kee Construction Pte Ltd v Ssangyong Engineering & Construction Co Ltd [2010] 1 SLR 658 had this to say: Thus, it seemed that when what was being alleged was an absolute lack of jurisdiction on the part of a particular tribunal or court to hear a particular dispute, ‘jurisdiction’ being used in the strict sense of capacity to hear, then if the tribunal concerned does not have such jurisdiction, any party to the dispute may assert the lack of jurisdiction at any stage and can never be held to be estopped from doing so or to have waived its right of protest. On the contrary, when it is a question of irregularity of procedure or contingent jurisdiction or non-compliance with a statutory condition precedent to the validity of a step in the litigation, such irregularity or non-compliance can be waived because the effect of the waiver would not be to create or confer any jurisdiction that did not previously exist.” (emphasis added) 23 [41] Indeed some jurisdictional challenges may involve convoluted facts combined with no less complicated questions of law to consider. The intention of Parliament under section 27(3) of the CIPAA is clearly not to ruffle and trouble the Adjudicator with such difficult question of mixed fact and law where jurisdiction is concerned, but to allow him to proceed as if he has jurisdiction and to hear the parties on the dispute and to make his finding of facts on the dispute and determine if there are any sums owing for work done or services rendered as claimed, taking into consideration the defenses and set-offs and then without prejudice to the rights of the party unhappy with the issue of jurisdiction, to allow that dissatisfied party to raise the jurisdictional challenge in the High Court. [42] In a case where there is no jurisdiction to begin with rather than one where there is jurisdiction but that the Adjudicator has exceeded his jurisdiction, the Court may even allow a determination to be made first before the Adjudication in a case that warrants it. [43] In View Esteem FC (supra) it was observed as follows: “[19] It is our considered view that the appellant had rightly not invoked s 15 of the CIPAA at the beginning in making its application to challenge jurisdiction because it could not on the one hand complain that CIPAA did not apply to the case and yet on the other 24 hand invoke a provision of CIPAA to seek relief. In the circumstances, our answer to question 1 posed in this appeal is in the positive in the first part and negative in the second part.” [44] Here the jurisdictional challenge seems to be one of contingent jurisdiction in that if there is a dispute within the meaning of section 6 of the CIPAA then the Adjudicator would have the jurisdiction to hear the matter. The Adjudicator was not obliged to give his reasons for concluding that he did have jurisdiction as section 27(3) allows him to proceed as if he has. However he had given his reasons in paragraphs 26-31 of his Adjudication Decision citing section 6(1) and the dicta of Swinton Thomas LJ in Halki Shipping Corp (supra) as quoted above. I agree with the reasons given. This ground that the Adjudicator has no jurisdiction to adjudicate under the CIPAA when clearly there was a dispute, is without merit and has to be dismissed. Whether the Claimant in the Adjudication ought to have proceeded afresh with the service of another Notice of Adjudication upon the first appointed Adjudicator declining to act or as Ireka contended, having resigned as the Adjudicator 25 [45] In this case the first Adjudicator had rejected his appointment as an Adjudicator by the Director of KLRCA which appointment was made under section 23 of the CIPAA. He himself said so in Exhibit NYS 5 to both parties and to KLRCA and the solicitors for both parties. [46] The time frame for his acceptance of appointment by KLRCA had not expired yet and so he had yet to accept his appointment. Section 23(2) of the CIPAA read as follows: “(2) The adjudicator shall propose and negotiate his terms of appointment including fees chargeable with the parties and shall within ten working days from the date he was notified of his appointment, indicate his acceptance and terms of his appointment.“ (emphasis aded) [47] The Adjudicator’s rejection of his appointment comes within section 23(3) of the CIPAA where he is entitled to reject his appointment before his acceptance of the appointment. Section 23(3) provides as follows: “(3) If the adjudicator rejects his appointment or fails to indicate his acceptance of the appointment within the period specified in subsection (2)-
