6 Having regard to his Honour's reasoning and the cases to which he referred, I think that the better view is as decided by his Honour, namely, that unless the particular dispute is raised in the affidavit filed within time, it cannot be dealt with in later affidavits. This is subject to the qualification, of course, that a genuine dispute arising out of a matter of law, which does not require evidence to support it, would, of course, always be available to be argued. See Callite v Peter John Adams & Ors [2001] NSWSC 52.
7 In these cases the offsetting claim cannot be raised.
8 The same problem arises in another area, namely, whether the work was authorised. In the later affidavit the deponents squarely raise the question whether it was authorised and it is necessary to see whether this also appears from the first affidavit of Mr Greenaway sworn 20 February 2001.
9 Paragraph 5, which is the main paragraph dealing with the words, states:
"I say there is a genuine dispute as to the existence and/or amount of the debt because of the following."
10 It then goes on to deal with a number of matters, including subclause (d) where the deponent queried items on the amount with which I am concerned.
11 Having regard to the commencing words in paragraph 5, I would have thought that that is sufficient to raise a suggestion as to whether the work in fact was authorised because it queries whether any amount was in existence at the time and date.
12 The defendant's affidavit really gave no admissible evidence as to the request for the work and, bearing in mind the sworn evidence of Mr Greenaway in his affidavit of 20 August 2002 that he did not authorise the work, there appears to be a dispute as to whether the work was authorised as requested.
13 The real question arises as to whether this is genuine. In this regard it seems to me there is in fact some doubt on this aspect. Mr Greenaway was on the site, saw the work being done, has paid moneys on account, and he has only addressed in detail a couple of matters in the account. They are related matters being known as items 3 and 4.
14 In my view, I do not think that the dispute as to the authorisation of the work was genuine, or rather, if I can put it another way, I have doubts as to whether that is the case. The matter is, however, put beyond doubt when one looks at the question of whether there is a dispute as to the amount of the claim. In the first affidavit in paragraph 5(e)(f) and (g) the deponent, Mr Greenaway, raises arguments with the actual amount and whether it was appropriate to fully charge them to his company.
15 He also raises questions about the amount of the hire, and the labour charges for labour. That affidavit was sworn in December, and in February 2002 he made the payment for $14,107.51. In his later affidavit in paragraph 8 he said:
"On 26 February 2002 the Plaintiff caused to be paid by electronic transfer to the Defendants Bank account sum of $14,107.51` being the retention amount which had become due and an amount of $10,000.00 which I considered was a reasonable estimate of the value of the unauthorised work. This estimate was made without regard to the defective work of the Defendant of which I was unaware at the time of payment. Annexed marked "H" is a copy of the Bank Statement showing the withdrawal of $14,112.51 being the above mentioned amount plus $5.00 Bank fee."
16 The deponent goes on to give evidence in the following paragraphs of the defective work which he refers to in that paragraph. Paragraph 8, to which I have referred, does, however, put the plaintiff's view as to what was a reasonable estimate of the value of the work.
17 The defendant, on the other hand, led no evidence to support the reasonableness of the amount of the charges other than tendering letters quantifying the claim and certain calculations. In other words, he has exposed the amount of the calculation but there is no evidence as to whether it is reasonable.
18 In those circumstances I have to consider whether there is a genuine dispute. I have had the benefit of a number of submissions in respect of the principles to be applied and I think the most useful summation of what is a genuine dispute is that given by McLelland CJ in Equity in Eyota Pty Limited v Hanave Pty Limited (1994) 12 ACLC 669. At page 671 His Honour mad the following comments in respect of the expression "genuine dispute":
"It is, however, necessary to consider the meaning of the expression 'genuine dispute' where it occurs in s.495H. In my opinion that expression connotes a plausible contention requiring investigation, and raises much the same sort of considerations as the 'serious question to be tried' criterion which arises on an application for an interlocutory injunction or for the extension or removal of a caveat. This does not mean that the Court must accept uncritically as giving rise to a genuine depute, every statement in an affidavit 'however equivocal, lacking in precision, inconsistent with undisputed contemporary documents or other statements by the same deponent, or inherently improbable in itself, it may be' not having 'sufficient prima facie plausibility to merit further investigation as to (its) truth' (cf Eng Mee Yong v Letchumanan (1980) APPLICANT 331 at 341), or 'a patently feeble legal argument, or an assertion of facts unsupported by evidence ' (cf South Australia v Wall (1980) 24 SASR 189 at 194).
But it does mean that, except in such an extreme case, a Court required to determine whether there is a genuine dispute should not embark upon an inquiry as to the credit of a witness or a deponent whose evidence is relied on as giving rise to the dispute. There is a clear difference between, on the one hand, determining whether there is a genuine dispute and, on the other hand, determining the merits of, or resolving, such a dispute. In Mibor Investments (at ACLC 1066; ACSR 366-7) Hayne J said, after referring to the state of the law prior to the enactment of Division 3 of Part 5.4 of the Corporations Law, and to the terms of Division 3:
'These matters, taken in combination, suggest that at least in most cases, it is not expected that the Court will embark upon any extended inquiry in order to determine whether there is a genuine dispute between the parties and certainly will not attempt to weigh the merits of that dispute. All that the legislation requires is that the Court conclude that there is a dispute and that it is a genuine dispute.'
