"…comply, without recourse to defences or cross claims not raised in the adjudication."
“I derive two principles of law from the authorities, which are relevant for present purposes. a. Where it follows logically from an adjudicator's decision that the employer is entitled to recover a specific sum by way of liquidated and ascertained damages, then the employer may set off that sum against monies payable to the contractor pursuant to the adjudicator's decision, provided that the employer has given proper notice (insofar as required). b. Where the entitlement to liquidated and ascertained damages has not been determined either expressly or impliedly by the adjudicator's decision, then the question whether the employer is entitled to set off liquidated and ascertained damages against sums awarded by the adjudicator will depend upon the terms of the contract and the circumstances of the case.”
“17. It is now well established law and practice in the context of construction adjudications that valid adjudicators' decisions are to be enforced in effect without set off or cross claims. So far as set offs or cross claims are concerned, the logic is that these are to be raised in the adjudication and the adjudicator either allows or disallows them; it is not then appropriate that the losing party raises on enforcement proceedings either the same set offs or cross claims (which have already been adjudicated upon) or new ones which could have been but were not raised. The policy of the HGCRA is that decisions are binding. This is wholly and clearly reflected in the contract terms set out above. Mr Justice Ramsey reviewed a number of authorities in this area in William Verry Ltd v London Borough of Camden[2006] EWHC 761 (TCC) , and said at Paragraph 43: "In such circumstances, should the sums found due in adjudication decision number 3 give way to the disputed valuation in the final certificate? In my judgment, they should not for the following reasons: First, for the reasons set out above, I consider that the binding nature of the adjudicator's decision and the agreement of the parties to comply with that decision means that, prima facie, the adjudicator's decision should be enforced. Secondly, if payment of an adjudication decision on the sum due on an interim certificate had to be subject to the view of the Contract Administrator/Quantity Surveyor in a subsequent certificate, then the intention of parliament and the purpose of adjudication would be defeated. Each successive certificate would defeat the decision by an adjudicator on the previous certificate." The logic of the second point in the dictum set out above is that the adjudicator's decision, if it requires payment, should be enforced and it is not subject to the diktat, approval or further certification under the construction contract… 20. One can draw from the David McLean decision the propositions that the Court must interpret adjudicators' decisions not only from the words used by the adjudicator but also in the context of the dispute which was referred to adjudication. There may be disputes between the parties as to whether money should be paid or should have been paid but there may also be disputes, as in the David McLean case, as to the true value of elements in a previous valuation. Put another way, the crystallised dispute may involve or require a declaration as to what the true value is or a directive decision that money be paid. This issue in any given case will depend on the facts of the case and the wording used in any given adjudicator's decision.”
“36. Since it is the decision of the adjudicator that is binding on the parties, not his reasoning, one must consider what is meant by "the decision of the adjudicator". In most cases the adjudicator will determine that a sum of money is due from one party to the other and the decision will therefore consist of a declaration that the particular sum is due, together with related declarations in relation to the amount of interest and questions of costs. In that type of decision, it is clear beyond doubt that the adjudicator's conclusion that A owes (and must pay) £X to B is binding until finally determined by litigation or arbitration. 37. However, suppose that the adjudicator's reason for deciding that the sum owed to B is £X is that he has decided that B was entitled to an extension of time of Y weeks with a weekly prolongation cost of £Z. In this situation, I find it difficult to see how it could be said that the amount of the extension of time to which B was found to be entitled was not also part of the decision and therefore not binding as between A and B (subject, of course, to B having the right to argue in a subsequent adjudication that he is entitled to a further extension of time on the grounds not put before the adjudicator in the first adjudication). In my judgment, in that situation an adjudicator's conclusion on the amount of the extension of time attributable to the stated events would also be binding on the parties (until finally determined otherwise). 38. Accordingly, I consider that an adjudicator's decision consists of (a) the actual award (i.e. that A is to pay £X to B) and (b) any other finding in relation to the rights of the parties that forms an essential component of or basis for that award (for example, in a decision awarding prolongation costs arising out of particular events, the amount of the extension of time to which the referring party was entitled in respect of those events).”
“11. In general, an unsuccessful party to an adjudication cannot seek to avoid the result of that adjudication by relying on the right to set-off any other claims: see VHE Construction PLC v RBSTB Trust Co Ltd[2000] BLR 187 . It has often been said that, where there are subsequent cross-claims, the right course is for the losing party to comply with the adjudicator's decision and not withhold payment on the ground of his anticipated recovery in a further claim: see Interserve Industrial Services Ltd v Cleveland Bridge UK Ltd[2006] EWHC 741 (TCC) and Hart v Smith[2009] EWHC 2223 (TCC) … 12. Possible exceptions to this general approach were summarised by Jackson J (as he then was) in Balfour Beatty Construction v Serco Ltd[2004] EWHC 3336 (TCC) , when he said at paragraph 53…[see above] 13. In similar vein, in William Verry Ltd v The Mayor of Burgesses of the London Borough of Camden[2006] EWHC 761 (TCC) , Ramsey J said that the right to set-off was generally excluded. As to the particular issue of whether liquidated damages could be deducted when the adjudicator's decision deals with extensions of time, but does not deal with the consequential effect of an undisputed or undisputable claim for liquidated damages, he said that that raised "a distinct question of the manner and extent of compliance with the adjudicator's decision. It does not, in my judgment, raise a question as to the ability to set-off sums generally against an adjudicator's decision." 14. The first possible exception to the general rule turns on the proper construction of the terms of the contract. There will be some cases, such as Parsons Plastics Ltd v Purac Ltd[2002] BLR 334 , where the contractual right to set-off may trump the enforcement of an adjudicator's decision. However, such cases will be relatively rare and will depend upon the precise construction of the relevant set-off provision. Clear words permitting the set-off against a sum otherwise due will usually be required. The more common analysis is that set out by the Court of Appeal in Ferson Contractors Ltd v Levolux AT Ltd[2003] BLR 118 , where Mantell LJ said that the contract had to be construed so as to give effect to the intention of Parliament, rather than to defeat it, and that if the set-off provision offended the requirement for immediate enforcement of the adjudicator's decision, it should be struck down. He distinguished Parsons on the basis that it was not concerned with section 108 of the 1996 Act and was instead concerned with a rather different ad hoc adjudication procedure. 15. The second exception has arisen out of the proper interpretation of the adjudicator's decision. If the adjudicator has decided that a certain sum must be paid by X to Y, often forthwith, it is difficult to see that there could be any room for an effective withholding notice from X, or an allowable set-off of X's cross-claims against the sum found due to Y by the adjudicator. But if the adjudicator's decision is instead in the nature of a declaration as to the proper operation of the contractual payment machinery, and the adjudicator identifies a sum which he says should be the subject of that machinery then, if a withholding notice can legitimately be served in accordance with those contractual payment provisions, the set-off may give rise to an arguable defence.”
“20. First, as a matter of law, my starting point must be that the right to make such a set-off has been generally excluded, because anything else would be contrary to the 1996 Act and the underlying purpose of construction adjudication. It would, in my view, be contrary to the 1996 Act if, at least in general terms, the effect of an adjudicator's decision could be avoided altogether by the subsequent service of a withholding notice. It would allow the unsuccessful party a defence to the claim merely because the adjudicator gave that party time to pay the sum due, rather than ordering payment forthwith. That is, to say the least, counter-intuitive; it would mean that the unsuccessful party was taking undue advantage of the adjudicator's decision to allow them some time to pay. In reaching that general conclusion I am, I think, doing no more than echoing what Mantell LJ said in Ferson, what Jackson J said in Balfour Beatty, and what Ramsey J said in William Verry. 21. Secondly, reading the adjudicator's decision as a whole as I must, I am firmly of the view that the adjudicator was not giving some kind of declaratory relief as to how the payment mechanism under the sub-contract might operate. He was not providing a declaration as to what sum was payable under the contract mechanism. He was not identifying a sum which he intended to 'plug in' to the contract machinery. Instead, in my view, the adjudicator was deciding a one-off claim in a one-off way. His decision makes plain that he intended the sum of£167,531.05 to be paid by no later than 14 days after his decision, namely by 5 June. On a proper reading of that decision, the adjudicator did not intend that there was to be any set-off or cross-claim in respect of that award. He was, as I have said, merely giving Vertase time to pay.”
