Genuine dispute
19It seems that the contractual arrangements of the parties were in two separate parts. The first was what has been described as a design contract in which the plaintiff provided the defendant with design instructions on 4 August 2009. Thereafter on three occasions in December further purchase orders were given for design work and these were paid for by the plaintiff. There was a further purchase order in December 2009 issued by the plaintiff for $44,226.44, which was not paid by the plaintiff, and that sum was included in the statutory demand.
20It should be appreciated that both the plaintiff and the defendant had substantial parts to play in the production of the crushing plant. By way of example, the contract which the plaintiff had with Hazell Brothers was for the sum of $4.7 million and the Becker Vale contract which the plaintiff entered into with the defendant was for the sum of $2.9 million and was focussed in general on providing the electrical installation and a number of other areas.
21Initially at the commencement of the matter there was some dispute as to whether the defendant's terms and conditions of trading were incorporated in the contract. However, in final submissions it was conceded that the contract was comprised of the documents specified in 12.13 of the plaintiff's submissions which were as follows:
"12.13 It is common ground that on or about 16 October 2009 the plaintiff entered into a contract with the defendant comprising the following documents:
(a) the Revision 2 Works Package Contract;
(b) the Vale Quotation,
(c) the 22 September Minutes; and
() the Global Purchase Order."
22It is common ground that the plaintiff contracted with the defendant to provide design work and mechanical and electrical work so, for ease of reference, the plaintiff adopted the defendant's terminology for the purposes of their submissions.
23The plaintiff's written submissions summarised the contract it had with the defendant as requiring the defendant to:
(a) undertake the electrical design, supply and installation of the crushing plant including starters, cabling, contactors, switches and software to run the start-up and shut-down sequencing of the plant, in order that the electrical installation was capable of being 'signed off' as fit for purpose by a suitably qualified and experienced person under the New South Wales Mining and Quarrying Regulations, and capable of running the crushing plant continuously for 24 hours a day 7 days a week, prior to commissioning;
(b) supply all documentation required for the operation and commissioning of the crushing plant, including a user manual and safety certification;
(c) design, manufacture and supply three screen support frames;
(d) design manufacture and supply 1 dual cone structure (i.e. a frame to support 2 compression crushers);
(e) design, manufacture and supply a trestle conveyor support frame;
(f) design, manufacture and supply the main radial stacker conveyor (CV1), which performs the function of stockpiling crushed rock above the reclaim tunnel;
(g) design, manufacture and supply a reclaim tunnel, for the purpose of moving rock material into the crushing plant, including the conveyor within the reclaim tunnel (CV2)
(h) design, manufacture and supply three under screen chutes and three under screen conveyors;
(i) design, manufacture and supply two rock boxes and one conveyor underneath the compression crusher;
(j) design, manufacture and supply two motor control centres and one air-conditioned site office;
(k) design, manufacture and supply walkways, handrails and stairs for the crushing plant; and
(l) project manage the Works,
so as to deliver a fully operational 'turn key' crushing and screening plant for handover to Hazell Brothers on 8 March 2010, which was subsequently amended to 14 March 2010 due to inclement weather and because it became apparent that the defendant was unable to meet the initial timeline, due to problems with the Works.
24Given that the defendant concedes that documents comprising the contract are as alleged by the plaintiff, the only remaining area of genuine dispute is whether there is any entitlement to progress payments under the contract. Plainly, under the contract there was no such provision. However, a number of progress claims were paid during the course of the contract until such time as the defendant fell behind in its performance of the contract.
25According to the plaintiff there is a genuine dispute because the entire contract that has never been completed, either on time or in accordance with its terms. It is thus said that there is no entitlement to any payment. The defendant submits that there has been substantial performance of the contract and therefore the plaintiff is restricted to an action for damages.
26It is necessary to consider the delays and failure to achieve the contractual requirements.
27The agreed due date for delivery in the contract was 15 March 2010. This was not achieved and by late April 2010 there had been continual delays in commissioning the plant because of electrical problems. These problems caused repeated tripping of the plant that led to the blockages when the plant backed up (known as 'buried'). There was no automatic start up and shut down function which was a necessary requirement and all the testing was done manually.
28On 29 April 2010 the defendant wrote a letter to the plaintiff saying they were unable to give a firm date for completion of the commission but hoped to have automatic mode operational by 30 April 2010.
29Apparently this did not happen because the problems continued and even in June 2010, the testing had to be carried out in manual mode as there was no automatic start up and shut down function.
30Production started in August 2010 but on 21 September 2010, Clive Cutler on behalf of Abbigroup (a member of the BWA), sent an email to James Kinross, on behalf of the plaintiff, in which he wrote:
"I have been watching the performance of the Cotter crushing plant for the last 5 - 6 months or so. Frankly, from my point of view it is a disaster and I could not in all conscience recommend your company to anyone looking for a turnkey plant. I am disappointed. Plant availability is somewhere in the 50-55% mark at best. Mechanical and particularly electrical breakdowns are commonplace almost every shift....I have not come back to you on Gladstone (which Abigroup won) because I wanted to see for myself just how Cotter would turn out after 6 months or so. There is no way known at the moment I could entertain your company at Gladstone to provide a screening plant.....My comments above in no way reflect adversely on your ability and reputation as a supplier of OEM [Original Equipment Manufacturer] equipment ie screens, feeders, crushers etc.....I have copied in Geoffrey Hazell as you can see because he owns the plant and should be worried."
31Eventually the plant operated through to the end of the crushing programme and that was completed at the end of May 2011 with the required amount of rock crushed and delivered. The delays involved reflect themselves in the offsetting claims which will be dealt with later.
32The defendant referred the well-known decision of Hoenig v Isaacs (1952) 2 All ER 176. That case was a contract to decorate a flat for 750 pounds with the terms of payment being "net cash as the work proceeds and the balance on completion". The defendant owner paid 400 pounds, occupied the flat and refused to pay the balance.
33Lord Denning said at page 180 the following:
"In determining this issue the first question is whether, on the true construction of the contract, entire performance was a condition precedent to payment. It was a lump sum contract, but that does not mean that entire performance was a condition precedent to payment. When a contract provides for a specific sum to be paid on completion of specified work, the courts lean against a construction of the contract which would deprive the contractor of any payment at all simply because there are some defects or omissions. The promise to complete the work is, therefore, construed as a term of the contract, but not as a condition. It is not every breach of that term which absolves the employer from his promise to pay the price, but only a breach which goes to the root of the contract, such as an abandonment of the work when it is only half done. Unless the breach does go to the root of the matter, the employer cannot resist payment of the price. He must pay it and bring a cross-claim for the defects and omissions, or, alternatively, set them up in diminution of the price. The measure is the amount which the work is worth less by reason of the defects and omissions, and is usually calculated by the cost of making them good: see Mondel v Steel ; H Dakin & Co Ltd v Lee , and the notes to Cutter v Powell in Smith's Leading Cases, 13th ed vol 2, pp 19-21. It is, of course, always open to the parties by express words to make entire performance a condition precedent. A familiar instance is when the contract provides for progress payments to be made as the work proceeds, but for retention money to be held until completion. Then entire performance is usually a condition precedent to payment of the retention money, but not, of course, to the progress payments. The contractor is entitled to payment pro rata as the work proceeds, less a deduction for retention money. But he is not entitled to the retention money until the work is entirely finished, without defects or omissions. In the present case the contract provided for "net cash, as the work proceeds; and balance on completion." If the balance could be regarded as retention money, then it might well be that the contractor ought to have done all the work correctly, without defects or omissions, in order to be entitled to the balance. But I do not think the balance should be regarded as retention money. Retention money is usually only ten per cent, or fifteen per cent, whereas this balance was more than fifty per cent I think this contract should be regarded as an ordinary lump sum contract. It was substantially performed. The contractor is entitled, therefore, to the contract price, less a deduction for the defects.
Even if entire performance was a condition precedent, nevertheless the result would be the same, because I think the condition was waived. It is always open to a party to waive a condition which is inserted for his benefit. What amounts to a waiver depends on the circumstances. If this was an entire contract, then, when the plaintiff tendered the work to the defendant as being a fulfilment of the contract, the defendant could have refused to accept it until the defects were made good, in which case he would not have been liable for the balance of the price until they were made good. But he did not refuse to accept the work. On the contrary, he entered into possession of the flat and used the furniture as his own, including the defective items. That was a clear waiver of the condition precedent. Just as in a sale of goods the buyer who accepts the goods can no longer treat a breach of condition as giving a right to reject but only a right to damages, so also in a contract for work and labour an employer who takes the benefit of the work can no longer treat entire performance as a condition precedent, but only as a term giving rise to damages. The case becomes then an ordinary lump sum contract governed by the principles laid down in Mondel v Steel and H Dakin & Co Ltd v Lee. The employer must, therefore, pay the contract price subject to a deduction for defects or omissions."
34There was a useful discussion by his Honour Justice McDougall in Cordon Investments Pty Limited v Lesdor Properties Pty Limited 1073 [2010] NSWSC 1073 . That was a case where, because of the nature of the dispute, substantial performance may not have been relevant. His Honour went on to discuss the matter in these terms:
"[163] Another way of putting what I have just said might be to say that the doctrine of substantial performance should have no application to an "entire contract": that is to say, a contract under which full and complete performance by one party of its obligations is necessary before that party is entitled to receive whatever is the agreed consideration for those obligations. That view commended itself to White J in ACN 002 804 702 (formerly Brooks Building) v McDonald [2009] NSWSC 610 at [102], [103]. However, cases such as Tan Hung Nguyen v Luxury Design Homes Pty Ltd [2004] NSWCA 178 appear to treat the doctrine of substantial performance as applicable to entire contracts.
...
[167] An alternative, and perhaps related, explanation of the basis upon which the tender of less than complete performance of an entire contractual obligation may, nonetheless, earn the contractual reward is waiver. See, for example, Pollock CB in Graves v Legg (1854) 9 Exch 709 ; 156 ER 304. Indeed, this was the alternative ground on which Denning LJ based his conclusion in Hoenig. This is not the place to examine the slippery and multifaceted concept of waiver (as to which, see the decision of the High Court of Australia in Agricultural and Rural Finance Pty Ltd v Gardiner (2008) 238 CLR 570. It is sufficient to say that, in some cases, a party to a contract who is entitled to receive the benefit of entire performance of the other party's obligations before performing its own may be held to have waived that entitlement if it accepts, or takes the benefit of, substantial performance. I return to the concept of waiver at [171] below."
35His Honour went on to discuss the nature of the alleged substantial performance in that case and commented:
"[169] Further, were it necessary to do so, I would accept Mr Hale's submission that Cordon did not substantially perform its obligations as to completion. The referee's finding, that the extent of defective, incomplete and non-conforming work was such that the works were not, or would not be, reasonably fit for occupation or use by an owner, makes this clear. Whatever is the test for "substantial completion", it must at least encompass that the works said to have been completed substantially are reasonably fit for their contemplated occupation and use."
36The contract was an entire contract, as it seems from the little documentation there was that it was simply expressed as a "lump sum pricing for $2,999,365 excluding GST". Subsequent meetings suggested that there would be retentions of 2.5 percent on commissioning and a further 2.5 percent eight weeks after successful commissioning.
37So far as substantial performance is concerned, there were expert reports available and the evidence made it clear that the installation by the defendant was sub-standard in many respects.
38The plaintiff accepted that there had been success achieved in the sense that by the end of the project all the rock was crushed, but suggested that this was because of its work in subsequently bringing the plant up to standard and rectifying faults said to be those of the defendant.
39In this regard, I note that there was one item of work that was not completed, namely, installation of the reclaim tunnel which should have been done by the defendant and which was in fact done by the plaintiff. The cost for this work is estimated at $174,573.10. The cost of actual rectification works which were also claimed in the offsetting claims are $61,221 and a claim for supplying further items that the defendant failed to supply pursuant to the contract amounting to $72,410. There was also a claim for cost of transporting items to site for rectification works on defective items of $6,700. The total costs of the rectification works are $140,331. In addition it seems that the head contractor Hazell Brothers did a substantial amount of rectification work and it has claimed that the amount due to it for this work is the sum of $700,000.
40In the context of the contract for $2,999,436 a rectification claim of $840,331 and an uncompleted works claim of $174,573.10 raises the question that there was no substantial performance.
41The determination of this question is not something which is appropriate for resolution in these proceedings. The question here is whether the claim that there was no substantial completion amounts to a genuine dispute on this aspect. If there is such a genuine dispute then the demand should be set aside.
42It would require an examination of whether the defects which were identified and which the plaintiff and Hazell Brothers subsequently rectified, were sufficiently serious to prevent the plant performing at an adequate rate without their rectification.
43Craig Struthers, the plaintiff's expert, who was called in to help rectify the problems in February, did a substantial amount of work, which included re-programming the plant. Mr Struthers himself commented, "I think the guys operating this plant need to be congratulated for putting up with a substandard system and get production through the plant." Plainly the plant was operating although with great difficulty by February. After the rectification, production continued through until the end of May 2011.
44Considering all these details it seems to me that there is at least a genuine dispute as to whether there was substantial performance of the contract and accordingly the demand should be set aside.
45So far as the principles are to be observed in terms of whether there is a genuine offsetting claim, these were usefully summarised by Brereton J in BBB Constructions Pty Ltd v Frankipile Australia Pty Ltd (2008) 68 ACSR 1 at [4] in these terms:
"The test for determining whether there is a genuine offsetting claim is whether the court is satisfied that there is a serious question to be tried that a party has an offsetting claim ( Scanhill Pty Ltd v Century21 Australasia (1993) 47 FCR 451; 120 ALR 173 ; 12 ACSR 341) or that the claim is not frivolous or vexatious: Chadwick Industries (South Coast) Pty Ltd v Condensing Vaporisers Pty Ltd (1994) 13 ACSR 37. In other words, the claim must be bona fide and a truly existing fact and not spurious, hypothetical, illusory or misconceived: Ozone Manufacturing Pty Ltd v DCT (2006) 94 SASR 269; [2006] SASC 91 at [46]. In Macleay Nominees Pty Ltd v Belle Property East Pty Ltd [2001] NSWSC 743 ( Macleay Nominees), Palmer J put it in the following terms (at [18]):
'[18] In my opinion, a genuine offsetting claim for the purposes of [Corporations Act] s 459H(1) and (2) means a claim on a cause of action advanced in good faith, for an amount claimed in good faith. "Good faith" means arguable on the basis of facts asserted with sufficient particularity to enable the Court to determine that the claim is not fanciful. In a claim for unliquidated damages for economic loss, the Court will not be able to determine whether the amount claimed is claimed in good faith unless the plaintiff adduces some evidence to show the basis upon which the loss is said to arise and how that loss is calculated. If such evidence is entirely lacking, the Court cannot find that there is a genuine offsetting claim for the purposes of s 459H(1) and (2).'"
46For completeness I will now deal with the offsetting claims.
