and then said at [71] and [72]:
"71. Dualcorp asserts that this approach could produce unfair outcomes where a claim has not been the subject of adjudication on the merits but has been rejected for want of evidence. It was submitted that because of the unfairness that would flow from precluding a claimant bolstering its evidence on another adjudication, it cannot have been intended that adjudications would be conclusive.
72. I do not agree. It is not at all unusual that persons seeking remedies in court or other forums have a once only opportunity to bring forward evidence and submission in support of their claim. This is in fact the usual situation and is consistent with what the High Court said in D'Orta [D'Orta-Ekenaike v Victoria Legal Aid (2005) 223 CLR 1] referred to as the "central and pervading tenet of the judicial system ... that controversies, once resolved, are not to be reopened except in a few, narrowly defined, circumstances (at [34])."
34. Allsop P agreed that the appeal should be dismissed but he did so, not on the basis of estoppel, but rather on the basis that s 13(5) and s 22(4) of the Act precluded any second adjudication.
35. The President said:
"13. I see no warrant under either the contract or the Act, s 8 for permitting a party in Dualcorp's position to create fresh reference dates by lodging the same claim for the same completed works in successive payment claims. That is not the intended operation of the last phrase of s 8(2)(b) ("and the last day of each subsequent named month").
14. Here, the work had been done; Dualcorp, the subcontractor, had left the site; it claimed payment by six invoices; six weeks later it repeated that claim by reference to the same invoices and, in my view, in respect of the same reference date. Dualcorp was prevented from serving the second payment claim. The terms of s 13(5) are a prohibition. The words "cannot serve more than one payment claim" are a sufficiently clear statutory indication that a document purporting to be a payment claim that is in respect of the same reference date as a previous claim is not a payment claim under the Act and does not attract the statutory regime of the Act.
15. For these reasons, Dualcorp was not entitled to proceed to judgment on a claim founded on the operation of the Act premised on the second payment claim of 3 March 2008 being a payment claim under the Act."
36. Allsop P also agreed (see [16]) with Macfarlan JA that the Act as a whole generally manifests an intention to prevent repetitious re-agitation of the same issues.
37. Dr Greinke argued that the majority view in Dualcorp did not impugn the second claim because the adjudicator had not determined the value of work under the construction contract but only determined that Mev had not made out a claim for a progress payment and had done so by rejecting Mev's contention on how the delivery period was to be construed. He submitted that the adjudicator had not determined the claim based on this new approach to the contract since such a claim had not been advanced. He also submitted that the adjudicator had not determined whether items claimed as missing had been returned or how the clauses were to be construed, rather the adjudicator had not been satisfied on the basis of evidence relied on by Mev and he said that the adjudicator had not determined what the value of work or services under the contract was.
38. The adjudicator made a determination that the 24 week period did not commence on the date of the first delivery of items, and in my view that issue is clearly the subject of an issue estoppel. That is an issue which by the second claim Mev seeks to re-agitate, although it also brings an alternative claim based on the approach to the terms that the adjudicator favoured, that is that each item could be viewed separately and the 24 week period commence in relation to each delivery. However, in my view what the adjudicator determined was wider than that. He determined, for the purposes of the Act only, that Mev was not entitled to any payment in respect of the invoices previously rendered. What Mev seeks to do, apart from re-agitating the construction issue that was determined adversely to it by the adjudicator, is to make minor alterations to the amounts claimed, present an alternative basis to its claim, and bring another claim over the same subject matter of the first claim when no further work or services have been rendered or goods supplied between the date of the first claim and the second.
39. I should note that the reference date in the first claim is 30 June 2008 and in the second 31 July 2008. On the face of the matters, no discernable reason for altering the reference dates, other than perhaps to enable it to be said the reference date is different, is present. In my view this does not avoid the problem that is found in s 13 of the Act and to which reference has already been made. S 13(5) and (6) provide:
"(5) A claimant cannot serve more than one payment claim in respect of each reference date under the construction contract.
(6) However, subsection (5) does not prevent the claimant from including in a payment claim an amount that has been the subject of a previous claim."
40. Dr Greinke argued that to prevent a party from bringing a second claim for the same work would be unfair given the short timeframes involved in the Act. Prior to a payment claim being served a claimant has ample time to prepare its claim and it ought give careful consideration to such a claim before serving it. Further, it is to be expected that invoices or progress claims on which payment claims are based will be themselves accurate and properly founded.
41. The view expressed in Dualcorp by Allsop P is consistent with Macfarlan JA's approach to the Act, but I accept the majority did not base their decision on this ground but rather adopted a perception of the Act (shared with Allsop P) to found a conclusion based on estoppel, and to express a tentative view about abuse of process, although in this context Macfarlan JA's conclusion as expressed in [18] that allowing the claimant to serve another claim and seek a redetermination of the same issues would be "contrary to the intent of the Act", is relevant.
42. The contention that a party, having put forward a claim framed in a particular way, when the claim is rejected may serve another claim framed in a different way is in my view entirely inconsistent with the object of the Act and the principle of finality to which Macfarlan JA referred in Dualcorp. In my view the second claim is incompetent because it ventilates issues which have already been decided. As a further ground I respectfully adopt the approach of Allsop P and also find that it is incompetent because the Act permits only one payment claim to be made in respect of the same work, services or goods supplied.
43. I now deal with the question of whether the court should intervene at this stage.
44. Dr Greinke drew my attention to a number of decisions such as Australian Remediation Services Pty Ltd v Earth Tech Engineering Pty Ltd [2005] NSWSC 362; Energetech Aust Pty Ltd v Sides Engineering Pty Ltd [2005] 226 ALR 362 ("Energetech"); Boutique Developments Limited v Construction and Contract Services [2007] NSWSC 1042 ("Boutique"); Lifestyle Retirement Projects No.2 Pty Ltd v Parisi Homes Pty Ltd [2005] NSWSC 411 ("Lifestyle") in which this Court has declined to injunct proceedings before an adjudicator on the basis that some element necessary for the compliance with the Act was missing, e.g. that the claim was not for services in relation to construction work: see Boutique; whether the claim was in time: see Lifestyle; whether the payment claimed infringed s 52 of the Trade Practices Act 1974 (Cth): see Energetech.
45. I accept these cases as establishing that where a party seeks to have a payment claim adjudicated this Court generally should leave issues that can be determined by the adjudicator, including matters that relate to jurisdiction, to the adjudicator.
46. None of these cases deal with the present situation, which is where an adjudication having been held and a determination given, the claimant seeks to propound a claim for the same works, goods or services.
47. In my view different considerations apply in this arena and for the following reasons:
(1) The approach taken in Dualcorp is that a second claim is not one that is within the intent of the Act and on the approach taken by Allsop P, a second claim is not one permitted by the Act and hence is not governed by the Act.
(2) As Mr Nicholls pointed out the remedy for abuse of process or issue estoppel is to apply for a dismissal or permanent stay of the proceedings, and there is no mechanism for such an application before an adjudicator.
(3) The continuation of the claim or proceedings is the very matter which the party asserts is the abuse. It is required to expend time and money and "is vexed" with a fresh process when it ought not to be.
(4) The intent of the Act is to provide a means of speedy determination of claims for payment to be made on an interim basis not to burden the parties to a construction contract with a prolonged quasi-litigious process.
(5) I think it is important not to lose sight of the fact that a determination under the Act produces no final result. It is a scheme for interim payment only and a party who is unsuccessful before the adjudicator has rights and remedies at law to correct any deficiencies in evidence or arguments at a final hearing: see s 32 of the Act.
48. This Court certainly does have power to restrain proceedings within the Court and in other tribunals: see Walton v Gardiner (1993) 177 CLR 378 and Buying Systems (Australia) Pty Ltd v Tien Mah Litho Printing Co (PTE) [1986] 5 NSWLR 317 ("Buying Systems").
49. It is a jurisdiction that should be exercised extremely sparingly: see Bryanston Finance Ltd v de Vries (No. 2) [1976] Ch 63 at 78 cited in Buying Systems, but that does not mean it should not be exercised when appropriate.
50. Where steps have been taken in breach of and/or against the intent of a statutory scheme I think it is part of this Court's function to step in and prevent that occurring.
51. In my view this is an appropriate case for intervention and the second claim ought not be permitted to proceed any further. Accordingly, I am of the view the relief which is sought by the plaintiff, should in broad terms, be granted but I will hear the parties on the precise form of orders that should be made.
