"... the Plaintiff is estopped from denying that the document dated1st October 1987 is or has the effect of, a Final Certificate."
"(5) (a) The measurement and valuation of the Works shall be completed within the Period of Final Measurement and Valuation stated in the Appendix to these Conditions, and the Contractor shall be supplied with a copy of the priced Bills of Variation not later than the end of the said Period and before the issue of the Final Certificate under sub-clause (6) of this Condition. (b) Either before or within a reasonable time after Practical Completion of the Works the Contractor shall send to the Architect/Supervising Officer all documents necessary for the purposes of the computations required by these Conditions including all documents relating to the accounts of nominated sub-contractors and nominated suppliers. ... (6) So soon as is practicable but before the expiration of the period the length of which is stated in the Appendix to these Conditions from the end of the Defects Liability Period also stated in the said Appendix or from completion of making good defects under clause 15 of these Conditions or from receipt by the Architect/Supervising Officer of the documents referred to in paragraph (b) of sub-clause (5) of this Condition, whichever is the latest, the Architect/Supervising Officer shall issue the Final Certificate. The Final Certificate shall state:- (a) The sum of the amounts already paid to the Contractor under Interim Certificates and Certificates issued under sub-clauses (4)(b) and (4) (c) of this Condition; and (b) The Contract Sum adjusted as necessary in accordance with the terms of these Conditions, and the difference (if any) between the two sums shall be expressed in the said certificate as a balance due to the Contractor from the Employer or to the Employer from the Contractor as the case may be, and subject to any deductions authorised by these Conditions, the said balance shall as from the fourteenth day after the issue of the said certificate be a debt payable as the case may be by the Employer to the Contractor or by the Contractor to the Employer. (7) (a) Except as provided in paragraphs (b) and (c) of this sub-clause (and save in respect of fraud) the Final Certificate shall have effect in any proceedings arising out of or in connection with this Contract (whether by arbitration under clause 35 of these Conditions or otherwise) as (i) conclusive evidence that where the quality of materials or the standards of workmanship are to be to the reasonable satisfaction of the Architect/Supervising Officer the same are to such satisfaction; and (ii) conclusive evidence that any necessary effect has been given to all the terms of this Contract which require an adjustment to be made of the Contract Sum save where there has been any accidental inclusion or exclusion of any work, materials, goods or figure in any computation or any arithmetical error in any computation, in which event the Final Certificate shall have effect as conclusive evidence as to all other computations."
"No particulars were sought or given as to the alleged estoppel or as to the facts relied on. It is clear from the evidence which I have heard that no representation was ever actually made by or on behalf of the plaintiff that the Certificate was a final certificate."
"The estoppel which Mr Black has sought to establish is not a common law estoppel based on actual representation of fact but an equitable or promissory estoppel based upon an agreement or understanding between Mr Roberts and Mr Slater at a meeting in 1988."
"[Tameside] is estopped from relying on the absence of a final certificate [in relation to the Fairfield Road contract] and the rights of the parties are to be determined as if a final certificate had been issued to [Barlows] in 1988."
"I accept the evidence of Mr Jones that he had not by October 1987 prepared any final account, and that further works still required to be done before he could arrive at the final value of the works. There were over 20 variations which still had not been finally valued. These are referred to in paragraphs 52 to 127 of his witness statement and further documentation would have been required from the defendant before the final account figure could be finalised. It is correct that a great deal of the work which was necessary to prepare a final account had actually been done and work on the major variations had actually been fed into the previous interim valuations but it is clear from Mr Jones's evidence that he was not in a position to produce or complete a final measurement and valuation of the works and that he did not actually do so. Mr Jones was in my judgment a reliable witness and his recollection of events was better than that of Mr Roberts who gave evidence on behalf of the defendant. It is clear in my judgment that the essential reason why a final account or to be more accurate the measurement and valuation referred to in Condition (30)(5)(a), had not been completed by October 1987 although the 12 months allowed for practical completion of the last of the works had expired in, at the latest August 1987, was because Mr Paul Keech, who had been dealing with the matter on behalf of the defendant in the agreeing of valuations with Mr Jones, had left the defendants' employ in December 1986 or January 1987 and neither his successor, Mr Stuart Keech, nor Mr Jones had pursued the matter of agreeing a final valuation. Mr Jones did not do so because he had other work to carry out which was more pressing. It is unclear why Mr Stuart Keech did not pursue the matter."
"The evidence of Mr Jones was that he had been called into the meeting by Mr Slater and had been asked by Mr Slater in Mr Roberts' presence to provide an indication of where he was up to with the Fairfield Road final account. Mr Jones then said that he had not finished the final account but he estimated that Tameside owed Barlows a little more money and that Mr Slater had then said something to the effect of Mr Jones being `... too honest for his own good ...' or `... honest to a fault ...'. Mr Jones had no doubt that he remembered this clearly and I accept his evidence. I also accept Mr Jones's evidence that by the time he left the meeting he had the impression that there was, as he put it in his witness statement, an `... agreement to draw a line under the matter.' When he was asked further about this in cross-examination, he said that he understood that he was `... not going to have to do any more work on the job ...' and when pressed whether he was saying something different from what he had meant when he had spoken about drawing a line under the matter, he said that he stood by the use of the words drawing a line and that he was not trying to say anything different. In response to questions from me after re-examination when I asked if his understanding was that Mr Slater and Mr Roberts had reached an agreement that no further payment would be sought and that that would be the end of the matter, his reply was `Certainly I had the impression that there would be no further payment and I am sure I came out with the impression - I cannot recall exactly what words were used - that I would have to do no further work on the account. I am pretty sure Mr Roberts said he was not looking for any money, and I understood that that would be the end of it.' He then went on to say that whatever had been agreed between Mr Roberts and Mr Slater had probably been agreed after he left the meeting and that there had not been any absolute statement that he was to do nothing more. He then said that he had gleaned the beginnings of that impression at the meeting, and he might have been told later by his line manager not to bother any further. He also said that he was the only person who would have done any work on preparing a final account."
"... the best evidence is that of Mr Jones ... `... a line was to be drawn under the matter.'"
"When parties agree, as Mr Roberts and Mr Slater must have agreed, that no further monies are payable on either side, they are in substance in my judgment in the context of Condition 30 actually agreeing that the balance in any final certificate is to be treated as a nil balance. If the question is asked how consistently with the terms of the contract is that agreement to be given effect to, the answer must, it seems to me, be that the parties have agreed the final certificate and not just the amount of the final measurement and valuation. Mr Stewart's submission that what was agreed at this meeting was restricted to the final account and to whether any further monies were payable does not in my judgment give sufficient effect to the evidence of Mr Jones that he had the impression that a line was being drawn under the matter. Nor does it explain why the Architect did not attempt to fulfil an otherwise outstanding obligation to issue a final certificate when the amount of the balance had been agreed. The circumstance that the defendant had not submitted the documents to enable Mr Jones to arrive at a final valuation cannot affect that aspect because for all practical purposes the figures had been agreed at the existing amounts as a result of the conversations at the meeting. The drawing of a line indicates in my judgment an intention that there should be finality in relation to the whole of the contract so far as there were remaining obligations to be performed on either side. The use of the term final account in the context of Condition 30 also points in the same direction and to more than a simple ascertainment of the value of the works. A final account suggests that the whole contract was being treated as having been finalised and that all outstanding matters were to be regarded as settled."
"In my judgment the plaintiff by agreeing to draw a line under the matter by implication represented that it was not necessary for the defendant to proceed any further with the process of obtaining a final certificate. By `the matter' what was being referred to was the whole contract, including the final certificate not just the value of the works as ascertained by measurement or valuation pursuant to Condition 30(5). Mr Stuart also submitted that there had not been any sufficiently clear or unambiguous representation giving rise to an enforceable estoppel. In my judgment, the intention was clear that all outstanding matters under the contract were to be regarded as having been performed and that nothing further remained to be done on either side. Effect should in my judgment be given to that unequivocal intention. In the present case the plaintiff impliedly represented that it was not necessary for the defendant to proceed further with the process of obtaining a final certificate and must be taken to have also represented that it would not enforce any right it might have to rely on in the absence of an actual final certificate . The truth was that the parties had agreed that matters had been concluded and the plaintiff cannot in my judgment now be heard to say that matters had not been concluded and that no final certificate had been issued."
"There is no evidence that Mr Roberts ever intended or contemplated on behalf of the defendant giving up anything beyond the small sum of money which Mr Jones said he estimated would be due to the defendant when the accounts were finalised. It is not necessary to imply any such term into what was agreed in order to give business efficacy to the transaction nor is the matter so obvious that if a bystander had asked was it intended that the protection afforded by a Final Certificate was to be given up, both Mr Slater and Mr Roberts would have answered `Yes'. Indeed if the question of what the parties had intended is to be approached by asking what they would have said if a bystander had asked what was to be the position in relation to the protection which a Final Certificate would afford to the defendant, I have no doubt that both Mr Roberts and Mr Slater would have said that the position was to be the same as if a Final Certificate had been issued"
"... the parties agreed to draw a line under the matter, that the matter was to be regarded as closed, and that nothing further was required to be done on either side in order to complete and finalise the contract."
"... even though this was not a sectional contract, the factual position is that the houses [referred to in the above two certificates] had been completed and possession had been given to the plaintiff. Significantly, separate certificates of practical completion had been issued. It these circumstances, it seems to me that it should be inferred that the parties had treated those parts of the work as being practically complete for all purposes, and I consider it would have been open to the plaintiff, if it had discovered defects in the houses which had been released to it, to have brought an action for failing to complete the houses properly and it would not have had to wait until the last of the works had been completed before suing. Time will have begun to run in respect of any of the defects ...from the dates of practical completion. The defects will have been suable on from that time"
