16 The solvency of Mr Hancock at the time of his death is clearly a relevant issue in the bankruptcy proceedings. Mr Hancock would have been solvent at the time of his death if, and only if, he was able to pay all his own debts as and when they became due and payable; s 5(2) Bankruptcy Act. It is the deed action that is most closely related to the question of Mr Hancock's solvency at the relevant time although there is a cogent argument that the outcome of the deed action would not affect the issue. Although in assessing Mr Hancock's solvency consideration would not be limited to his cash resources it would be necessary to consider the resources that he could realise within 'a relatively short time'; Sandell v Porter (1966) 115 CLR 666 at 670. As the trustee has pointed out, the deed action was commenced on 8 September 1992 and to date remains unresolved. The pleadings in that action have not yet closed. In short, there seems to be little real prospect of the prompt resolution of the deed action. The conspiracy action was commenced on 9 July 1996. The pleadings in that action have not yet closed and there is apparently an unresolved dispute in relation to an application filed by the Porteous interests in December 2002 seeking to amend the originating process.
17 It may be that the cross-vesting of the bankruptcy proceedings to the Supreme Court of Western Australia would save time and reduce expense by having factual matters determined in one court. Cross-vesting would also prevent the possible re-agitation in the Supreme Court of Western Australia of matters heard before this Court, thereby avoiding any difficulties associated with any inconsistent findings. However, it is clear that the WA proceedings involve complex litigation and there is no guarantee that, if transferred, the bankruptcy proceedings would be heard with those proceedings. That is a matter solely within the discretion of the Western Australian Supreme Court and I do not presume to anticipate the orders of that court. What is clear, however is that were all the proceedings to be heard together it would burden entities not party to the bankruptcy proceedings with the issues relevant thereto as well as entangling the trustee in very complex and time consuming proceedings predominately irrelevant to the bankruptcy issues. That may be a reason for the Supreme Court of Western Australia to hear them separately in which case the supposed value of cross-vesting would disappear.
18 I am of the view than any inconvenience and expense occasioned by the hearing of similar evidence in this Court and the Supreme Court of Western Australia would be less than the inconvenience and expense occasioned by cross-vesting the bankruptcy proceedings. The issues in the bankruptcy proceedings are discrete from many of those in the WA proceedings and the bankruptcy proceedings are at a relatively advanced stage. The WA proceedings have made little progress and nothing that has been put before me suggests that progress is now imminent. It would not be in the interests of justice to cross-vest the bankruptcy proceedings to the Supreme Court of Western Australia, where there is no indication as to when they will be heard, nor any indication that they will eventually be heard with either of the WA proceedings.
19 Although the Porteous interests have expressed concern about issue-estoppel arising from decisions of this Court, it must be remembered that this doctrine will affect only parties to the bankruptcy proceedings. The doctrine was neatly summarised by Dixon J (as he then was) in Blair v Curran (1939) 62 CLR 464 at 531-2:
'A judicial determination directly involving an issue of fact or of law disposes once for all of the issue, so that it cannot afterwards be raised between the same parties or their privies. The estoppel covers only those matters which the prior judgment, decree or order necessarily established as the legal foundation or justification of its conclusion, whether that conclusion is that a money sum be recovered or that the doing of an act be commanded or be restrained or that rights be declared.
…
In matters of fact the issue-estoppel is confined to those ultimate facts which form the ingredients in the cause of action, that is, the title to the right established. Where the conclusion is against the existence of a right or claim which in point of law depends upon a number of ingredients or ultimate facts the absence of any one of which would be enough to defeat the claim, the estoppel covers only the actual ground upon which the existence of the right was negatived. But in neither case is the estoppel confined to the final legal conclusion expressed in the judgment, decision or order… the judicial determination concludes, not merely as to the point actually decided, but as to a matter which it was necessary to decide and which was actually decided as the groundwork of the decision itself, though not then directly the point at issue. Matters cardinal to the latter claim or contention cannot be raised if to raise them is necessarily to assert that the former decision was erroneous…
But matters of law and fact which are subsidiary or collateral are not covered by the estoppel. Findings, however deliberate and formal, which concern only evidentiary facts and not ultimate facts forming the very title to rights give rise to no preclusion.'
20 In light of my findings that it would not otherwise be in the interests of justice to cross-vest the bankruptcy proceedings I am not convinced that the spectre of inconsistent findings by this Court and by the Supreme Court of Western Australia is sufficient to justify cross-vesting the proceedings on that basis.
