21 During cross-examination Mr Field changed his evidence so that the discussion with Mr Field took place on 18 December 2007 before the discussion with Mr Sender. Mr Field also gave evidence of another discussion he had had with Mr Sender in January 2008 in which Mr Sender apparently acquiesced in the existence of an arrangement to bill St George.
22 Mr Dwyer's evidence, on the other hand, was directed to establishing two propositions: first, that in December 2007 no agreement was reached with Grant Thornton about the identity of the company which would receive the bills; secondly, that in any event, the agreement between him and Grant Thornton was that its bills would only be payable in the event that it secured a refinancing arrangement for the group.
23 Mr Field gave evidence that the identity of St George was mentioned in his discussion with Mr Dwyer. He also said that the discussion took place after he had had the discussion with Mr Sender. As I have said he accepted under cross-examination that the discussion took place before his discussion with Mr Sender.
24 On the other hand, Mr Dwyer denies that St George was mentioned at all. Mr Wijesinghe, who was present during the discussion, denies that St George was mentioned. The situation then is that two witnesses, Mr Field and Mr Wijesinghe, say St George was not mentioned and Mr Field says that it was.
25 It is difficult to avoid the conclusion that there is a genuine dispute about that matter. That, of course, directly impacts on the question of whether the discussion with Mr Sender took place in the terms alleged or at all.
26 Mr Dwyer gave evidence that he believed that the arrangement was subject to the contingency of Grant Thornton successfully arranging for the group to be refinanced. It is clear that on several occasions Mr Dwyer said that if the refinancing occurred then Grant Thornton would be paid. It is not difficult to see how that statement might be understood as meaning to Mr Dwyer that the refinancing was subject to a contingency and to Mr Field as meaning that it was subject to timing.
27 The question which immediately arises is whether there is a genuine dispute about the debt. There is no reason to think that that question is to be answered according to a different standard in the context of s 459S than in an application to set aside a statutory demand under s 459G. The threshold, of course, for a conclusion that a dispute is genuine is a low one and not difficult to satisfy: Roadships Logistics Ltd v Tree [2007] NSWSC 1084 at [24] per Barrett J. I have little trouble in concluding in this case that there is a genuine dispute as to the existence of the debt. Applying the approach indicated by White J in Radiancy (Sales) Pty Ltd v Bimat Pty Ltd [2007] NSWSC 962 it follows that the application should be dismissed because it is an abuse of process.
28 There are two further matters which however deserve comment. First, St George submitted that I should decide the question of whether the debt was actually due. Support for this approach was said to be found in Brinds Ltd v Offshore Oil NL (1985) 63 ALR 94 at 99 per Lord Brightman. Grant Thornton did not oppose this course and made specific reference to Re QBS Pty Ltd [1967] Qd R 218 at 225 per Gibbs J and Ocean City Ltd v Southern Ocean Hotels Pty Ltd (1993) 10 ACSR 483 at 486 per French J. However, as was explained by White J in Tokich Holdings Pty Ltd v Sheraton Constructions (NSW) Pty Ltd (in liq) [2004] NSWSC 527 at [72] and [82] the winding up jurisdiction is not ordinarily to be used to resolve disputed debts.
29 Before me Mr Dwyer, Mr Field and Mr Wijesinghe were cross-examined. Extensive written submissions were received on who should be believed. However, the critical witness, Mr Sender, was not available. There is, it seems to me, an air of unreality in deciding whether the debt exists without Mr Sender's assistance. He was the chief financial officer for the group and was clearly involved in an intimate way with its accounting affairs. The evidence before me indicated that Mr Sender did not wish to give evidence but was available. It is plain that if Mr Sender gave evidence most of the issues in the case would readily be resolved. I do not think that this Court should embark upon an analysis of what happened between the parties in the absence of Mr Sender. Either party could have issued a subpoena ad testificandum to him; neither did.
30 There will be occasions when it is appropriate to determine a disputed debt. However, the exercise of that power should be informed by an appreciation of the difference between a winding up proceeding, which is concerned with status and into which questions of public interest intrude, and private suits for debts into which the public interest does not. Where a court determining winding up proceedings is asked to ascertain whether a particular debt exists, it is important that that question be determined correctly and not as the result of tactical manoeuvres between the parties. Here, so it seems to me, I could not be confident about the correctness of the outcome without Mr Sender's evidence.
31 There was some evidence before me that Mr Sender told Mr Field that he had no recollection of the relevant discussions. At the time that evidence was elicited I indicated that I was minded to admit it subject to a direction that its use be limited to proving only that that was what Mr Sender had said. I so direct.
32 In all those circumstances, I do not think it appropriate to determine whether the debt exists. That conclusion may serve to emphasise that once leave is granted under s 459S a creditor is in much the same position, tactically, as it is once an application is made against it under s 459G. Once such an order is made the creditor is exposed to the risk posed by the low threshold necessary to show the existence of a genuine dispute under s 459G. The manner in which this proceeding has unfolded serves to illustrate those problems. It may well be very difficult for a creditor to prevail once leave has been granted under s 459S for that grant of leave will usually carry with it an implicit positive assessment of the prospects of a genuine dispute being established.
33 It was said by Grant Thornton that I should, in any event, conclude that St George was insolvent. Having concluded that there was a genuine dispute about the debt that is sufficient to dispose of Grant Thornton's standing to seek those orders: Tokich at [77]. However, quite apart from that, a necessary corollary of my decision to grant leave under s 459S was that the existence of the debt was pivotal to the question of St George's solvency. St George proffered an admission during that leave application that if the debt did exist it was insolvent and if the debt did not exist it was solvent. Of course, I accept that it was not possible for St George to admit its way into solvency. However, Grant Thornton did not oppose the grant of leave under s 459S once St George had proffered that admission.
34 It would, in my opinion, be an abuse of process for Grant Thornton now to be permitted to say that, in fact, the existence of the debt was not material to the solvency of St George. The time for it to make that submission was at the time that the application for leave pursuant to s 459S was made. Leave having been granted the case cannot go forward on a basis inconsistent with that grant of leave. This is not to apply principles of issue estoppel or res judicata - clearly inapplicable in an interlocutory context - rather, it is to give effect to the principle that a party is bound by the way it conducts its case. St George conceded that the debt was material to solvency; Grant Thornton conceded that leave should be granted. If a creditor wishes to submit that a defendant is insolvent come what may it must first seek a revocation of the grant of leave under s 459S. Where, as here, the grant of leave under s 459S was not opposed this may be difficult. The ordinary principles by which interlocutory orders may be revoked will be pertinent. Change of circumstance, no doubt, will have its part to play. Mere change of mind by a creditor does not.
35 The application is dismissed with costs.
