“107…Both the HGCRA and the Amended Act create a hierarchy of obligations, as discussed earlier. The immediate statutory obligation is to pay the notified sum as set out in section 111. As required by section 108 of the Amended Act, the contract also contains an adjudication regime for the resolution of all disputes, including any disputes about the true value of work done under clause 4.7. As a matter of statutory construction and under the terms of this contract, the adjudication provisions are subordinate to the payment provisions in section 111. Section 111 (unlike the adjudication provisions of the Act) is of direct effect. It requires payment of a specific sum within a short period of time. The Act has created both the prompt payment regime and the adjudication regime. The Act cannot sensibly be construed as permitting the adjudication regime to trump the prompt payment regime. Therefore, both the Act and the contract must be construed as prohibiting the employer from embarking upon an adjudication to obtain a re-valuation of the work before he has complied with his immediate payment obligation.”
“[76] Thus, it is now clear that: (i) where a valid application for payment has been made, an employer who fails to issue a valid Payment Notice or Pay Less Notice must pay the ‘notified sum’ in accordance with s 111 of the 1996 Act; (ii) s 111 of the 1996 Act creates an immediate obligation to pay the ‘notified sum’; (iii) an employer is entitled to exercise its right to adjudicate pursuant to s 108 of the 1996 Act to establish the ‘true valuation’ of the work, potentially requiring repayment of the ‘notified sum’ by the contractor; (iv) the entitlement to commence a ‘true value’ adjudication under s 108 is subjugated to the immediate payment obligation in s 111; (v) unless and until an employer has complied with its immediate payment obligation under s 111, it is not entitled to commence, or rely on, a ‘true value’ adjudication under s 108.”
“44. This raises the question whether PAML can now raise a “true value” final account adjudication without first paying the sum awarded in Adjudication No. 1 [a notified sum adjudication in relation to an interim payment application]. Mr. Townend’s answer to that question is “yes” because of Adjudication No. 3 and because the “true value” adjudication is of the final account post-termination. 45. Whilst the S & T decision does not expressly concern the present situation, where what is suggested as the possible subject of an as yet unstarted adjudication is the determination of a notional final account where the amount of that final account would be dependant on the validity of Decision No. 1 , the ability to mount such an adjudication … attacking the validity of that Decision without prior payment of the amount awarded in Decision No. 1 would be a remarkable intrusion into the principle established in S & T: it would permit the adjudication system to trump the prompt payment regime, which is exactly what the Court of Appeal said in paragraph [107] of that case would not be permitted to happen. 47. Accordingly, in my judgment it is not open to PAML to seek to challenge the conclusion of the Adjudicator in Decision No. 1 in another adjudication without first paying the amount held due in Decision No. 1.”
