“Requirement to pay notified sum (1) Subject as follows, where a payment is provided for by a construction contract, the payer must pay the notified sum (to the extent not already paid) on or before the final date for payment. (2) For the purposes of this section, the “notified sum” in relation to any payment provided for by a construction contract means— (a) in a case where a notice complying with section 110A(2) has been given pursuant to and in accordance with a requirement of the contract, the amount specified in that notice; (b) in a case where a notice complying with section 110A(3) has been given pursuant to and in accordance with a requirement of the contract, the amount specified in that notice; (c) in a case where a notice complying with section 110A(3) has been given pursuant to and in accordance with section 110B(2), the amount specified in that notice. (3) The payer or a specified person may in accordance with this section give to the payee a notice of the payer's intention to pay less than the notified sum. (4) A notice under subsection (3) must specify— (a) the sum that the payer considers to be due on the date the notice is served, and (b) the basis on which that sum is calculated. It is immaterial for the purposes of this subsection that the sum referred to in paragraph (a) or (b) may be zero. (5) A notice under subsection (3)— (a) must be given not later than the prescribed period before the final date for payment, and (b) in a case referred to in subsection (2)(b) or (c), may not be given before the notice by reference to which the notified sum is determined. (6) Where a notice is given under subsection (3), subsection (1) applies only in respect of the sum specified pursuant to subsection (4)(a). (7) In subsection (5), “prescribed period” means— (a) such period as the parties may agree, or (b) in the absence of such agreement, the period provided by the Scheme for Construction Contracts.” (a) in a case where a notice complying with section 110A(2) has been given pursuant to and in accordance with a requirement of the contract, the amount specified in that notice; (b) in a case where a notice complying with section 110A(3) has been given pursuant to and in accordance with a requirement of the contract, the amount specified in that notice; (c) in a case where a notice complying with section 110A(3) has been given pursuant to and in accordance with section 110B(2), the amount specified in that notice. (a) the sum that the payer considers to be due on the date the notice is served, and (b) the basis on which that sum is calculated. (a) must be given not later than the prescribed period before the final date for payment, and (b) in a case referred to in subsection (2)(b) or (c), may not be given before the notice by reference to which the notified sum is determined. (a) such period as the parties may agree, or (b) in the absence of such agreement, the period provided by the Scheme for Construction Contracts.”
“9 – (1) An adjudicator may resign at any time on giving notice in writing to the parties to the dispute. (2) An adjudicator must resign where the dispute is the same or substantially the same as one which has previously been referred to adjudication and a decision has been taken in that adjudication.”
“Payment notice 9.—(1) Where the parties to a construction contract fail, in relation to a payment provided for by the contract, to provide for the issue of a payment notice pursuant to section 110A(1) of the Act, the provisions of this paragraph apply. (2) The payer must, not later than five days after the payment due date, give a notice to the payee complying with sub-paragraph (3). (3) A notice complies with this sub-paragraph if it specifies the sum that the payer considers to be due or to have been due at the payment due date and the basis on which that sum is calculated. (4) For the purposes of this paragraph, it is immaterial that the sum referred to in subparagraph (3) may be zero. (5) A payment provided for by the contract includes any payment of the kind mentioned in paragraph 2, 5, 6, or 7 above. Notice of intention to pay less than the notified sum 10. Where, in relation to a notice of intention to pay less than the notified sum mentioned in section 111(3) of the Act, the parties fail to agree the prescribed period mentioned in section 111(5), that notice must be given not later than seven days before the final date for payment determined either in accordance with the construction contract, or where no such provision is made in the contract, in accordance with paragraph 8 above.”
“i. That the Value of the Contract Works (as per Priced Document: Contract Sum Analysis) is the sum of£340,032,60 or such other sum as the Adjudicator shall decide; ii. That the value of Variations and/or loss and/or expense and/or damages is in the sum of -£5,473,01 or such other sum as the Adjudicator shall decide; iii.

That the value of abatement and/or set off for defective works is in the sum of£45,400.00 or such other sum as the Adjudicator shall decide; v. As to the amount due from Harding to us or from us to Harding as applicable;…”
“31. Section 108(3) of the 1996 Act and paragraph 23 of the Scheme provide for the temporary binding finality of an adjudicator's decision. More than one adjudication is permissible, provided a second adjudicator is not asked to decide again that which the first adjudicator has already decided. Indeed paragraph 9(2) of the Scheme obliges an adjudicator to resign where the dispute is the same or substantially the same as one which has previously been referred to adjudication and a decision has been taken in that adjudication. 32. So the question in each case is, what did the first adjudicator decide? The first source of the answer to that question will be the actual decision of the first adjudicator. In the present appeal, Mr Holt did not even take us to the first adjudicator's decision, although he was invited more than once by the court to do so. He was conscious, no doubt, that it would show, as it does, that the decision was limited to the grounds for extension of time in the two letters. 33. The scope of an adjudicator's decision will, of course, normally be defined by the scope of the dispute that was referred for adjudication. This is the plain expectation to be derived from section 108 of the 1996 Act and paragraphs 9(2) and 23 of the Scheme. That is also the plain expectation of paragraph 9(4) of the Scheme, which refers to a dispute which varies significantly from the dispute referred to the adjudicator in the referral notice and which for that reason he is not competent to decide. There may of course be some flexibility, in that the scope of a dispute referred for adjudication might by agreement be varied in the course of the adjudication.”
“Whether dispute A is substantially the same as dispute B is a question of fact and degree. If the contractor identifies the same Relevant Event in successive applications for extensions of time, but gives different particulars of its expected effects, the differences may or may not be sufficient to lead to the conclusion that the two disputes are not substantially the same. All the more so if the particulars of expected effects are the same, but the evidence by which the contractor seeks to prove them is different.”
“CONCLUSION Accordingly, the dispute hereby referred and what MJH seeks is: 159.1. pursuant to, amongst others, paragraphs 20 to 26 above [these paragraphs rely upon section 111 of the 1996 Act and the lack of a valid Pay Less notice], a Decision that the Employer must and shall immediately pay MJH the sum of£397,912.48 being the outstanding sum under the Contract since6 September 2014 or such other sum as the Adjudicator shall decide; 159.2 in the alternative, without prejudice to MJH’s primary position which is expressly reserved, a Decision that after taking into account amounts actually and physically previously paid to MJH under the Contract the amount properly due to MJH in respect of the account and that shall be paid by the Employer to MJH on or before6 September 2014 , without deduction of any retention, (or any other sum for that matter), shall be the sum of£397,912.48 in accordance with MJH’s Cl.8.12 Account (which forms Exhibit A attached hereto) or such other sum as the Adjudicator shall decide.”
“185. For the avoidance of doubt, I stress that I have not decided on the merits of Harding’s valuation and have not decided that£397,912.48 represents a correct valuation of the works. The parties made submissions in this adjudication about the proper valuation but these did not fall to be considered by me because of the rule relating to a notified sum becoming automatically due in the absence of a valid pay-less notice.”
“What Lidl might have done, after Mr Bergin’s decision, was to have sought a declaration from an adjudicator as to what is quite clearly in dispute which is the true value of the final account.”
“Sheriff Taylor's analysis, once articulated, is obviously right. And it has a series of advantages: (a) It makes irrelevant the problem with the narrow construction – namely that Parliament was setting up a complex and fuzzy line between sums due on the one hand and counterclaims on the other – a line somewhere to be drawn between set-off, claims for breach of contract which do no more than reduce the sum due and claims which go further, abatement and so on. (b) It provides a fair solution, preserving the builder's cash flow but not preventing the client who has not issued a withholding notice from raising the disputed items in adjudication or even legal proceedings. (c) It requires the client who is going to withhold to be specific in his notice about how much he is withholding and why, thus limiting the amount of withholding to specific points. And these must be raised early. (d) It does not preclude the client who has paid from subsequently showing he has overpaid. If he has overpaid on an interim certificate the matter can be put right in subsequent certificates. Otherwise he can raise the matter by way of adjudication or if necessary arbitration or legal proceedings.”
“18. I held [in ISG v Seevic] that if an employer fails to serve the relevant notices under this form of contract it must be deemed to have agreed the valuation stated in the relevant interim application, right or wrong. Accordingly, the adjudicator must be taken to have decided the question of the value of the work carried out by the contractor for the purposes of the interim application in question. 19. However, I made it clear that this agreement as to the amount stated in a particular interim application (and hence as to the value of the work on the relevant valuation date) could not constitute any agreement as to the value of the work at some other date (see paragraph 31). 20. This means that the employer cannot bring a second adjudication to determine the value of the work at the valuation date of the interim application in question. But it does not mean any more. There is nothing to prevent the employer challenging the value of the work on the next application, even if he is contending for a figure that is lower than the (unchallenged) amount stated in the previous application. If this was not made clear by my judgment, then it should have been, and it is certainly made clear by the decision of the Court of Appeal in Rupert Morgan Building Services (LLC) Ltd v Jervis[2004] 1 WLR 1867 , in particular the passage from paragraph 14 that is set out in paragraph 30 below. My judgment in ISG v Seevic was not intended to go behind that.”
