67 As to the first - whether the relevant proceeding would but for cross-vesting and accrued jurisdiction have been incapable of being instituted in the Supreme Court and capable of being instituted in the Family Court - the equity suit was plainly capable of being instituted in the Supreme Court. The jurisdiction of the Supreme Court to entertain it does not depend on any law relating to cross-vesting. But for the pendency of Betty's application in the Family Court, no question of the proceedings being brought in the Family Court would have arisen. As the matrimonial proceedings were already pending when the equity suit were instituted, the proceedings could also have been instituted in the Family Court, but only in reliance on accrued jurisdiction. Accordingly, this factor suggests that the Supreme Court is more appropriate.
68 As to the second - the extent to which the matters for determination in the relevant proceeding arise under a law of the Commonwealth and are not otherwise within the jurisdiction of the Supreme Court - the matters for determination in the equity suit do not arise under or involve questions as to the application or validity of a Commonwealth law, and are within the jurisdiction of the Supreme Court in any event. This factor therefore also suggests that the Supreme Court is the more appropriate.
69 That leaves to the third factor, the interests of justice. The question is simply whether, assuming that the jurisdiction of the transferor court has been regularly invoked, it is in the interests of justice that the proceedings be heard and determined in the transferee court, there being a statutory obligation to transfer the proceedings to that court whenever it appears to be in the interests of justice to do so - for which purpose it is both necessary and sufficient that the transferee court be the "more appropriate" forum [BHP Billiton Ltd v Schultz (2004) 221 CLR 400, 421 [14], 434-5 [63]]. In identifying the "more appropriate forum", relevant considerations include the cost and efficiency of proceedings in the respective jurisdictions, and the "connecting factors" described by Lord Goff in Spiliada Maritime Corporation v Cansulex Ltd [1987] AC 460, 478 - including matters of convenience and expense such as availability of witnesses, the places where the parties respectively reside or carry on business, and the law governing the relevant transaction [BHP v Schultz, 422 [18]]. Consideration of relevant connecting factors may identify a "natural forum" [BHP v Schultz, 423 [19]; cf British American Tobacco Australia Ltd v Gordon [2007] NSWSC 230, [44]]. As Schultz makes clear, the interests of justice concern those of both parties, and rather than the selection of the most advantageous, or least disadvantageous, forum for one of them, the "interests of justice" are to be judged by more objective factors, such as facilitate identification of the "natural forum", in which objectively judged it might be expected that the dispute would fall to be resolved, with its concomitant juridical advantages and disadvantages for each party, whatever they may be [cf British American Tobacco v Gordon, [47]].
70 I reject the submission, advanced on behalf of Bobby, that the applicant for a transfer bears some onus or has to show some good reason for disturbing the plaintiffs' initial choice of venue, or that the plaintiff's choice of court is to be given weight; despite earlier suggestions to that effect [Global Technology Australasia Limited v Bank of Queensland [2001] VSC 230; Bourke v State Bank of New South Wales (1988) 22 FCR 378; Kenda v Johnson (1992) 15 Fam LR 369, (1993) FLC ¶92-331, 79,505; Re Chapman & Jansen (1990) 13 Fam LR 853, FLC 92-139; Bankinvest AG v Seabrook (1988) 14 NSWLR 711], it is now established that an applicant for a transfer bears no burden of persuasion or onus of proof [BHP v Schultz at 437 [71]; Bankinvest AG v Seabrook, 727], and no particular significance attends the plaintiff's original choice of forum [BHP v Schultz, 425-6 [26]-[27], 439 [77]; British American Tobacco v Gordon, [43]]. It is only if both courts are equally appropriate that the initial choice will have significance; if one is more appropriate than the other, however so slightly, a transfer to the more appropriate court is mandatory.
71 The present is not a case in which geographical or local connection or the availability and convenience of witnesses is of significance; whether in the Supreme Court or the Family Court, the proceedings would likely be heard in Sydney, or possibly in Wollongong; neither court offers any advantage over the other in this respect.
72 Contrary to the submissions for Bobby, I do not accept that in the circumstances of this case the provision of the February 2004 deed, that it shall be governed by the laws of New South Wales, is significant: it relates to choice of law and not choice of court, and either court can equally apply the law of New South Wales. Insofar as it applies the general law, the Family Court sitting in New South Wales will apply the general law of New South Wales. This provision does not assist in identifying, in the present context, which court is the natural or more appropriate forum.
73 Nor is the professed inexpertise of Mick and Angelina's lawyers in the Family Court a matter of moment, particularly since the appropriateness of the Family Court as the forum had been raised from the outset of their intervention, and that they will be required to respond to Betty's amended application in the matrimonial proceedings in any event. A party cannot dictate the appropriateness of a forum by selection of particular lawyers.
74 Nor is the expected time to hearing a factor that favours retaining the equity suit in this court in this case, though it may be influential in some. There is evidence that, if transferred to the Family Court, the consolidated proceedings are not likely to be allocated a hearing date before about November 2007. If I could be confident that the equity suit could be heard and determined before then, without disrupting the preparation and progress of the matrimonial proceedings, then there might be more to be said in favour of determining them in this Court, although considerations of duplication would still point in the other direction. But the equity suit is unlikely to be heard in this court significantly before November 2007, and if the Family Court did not restrain their prosecution, it would probably adjourn the matrimonial proceedings until after their determination, further delaying the ultimate resolution of issues in the matrimonial proceedings between Bobby and Betty.
75 However, it is significant, in identifying the "more appropriate forum" for the equity suit, that the factual context for both proceedings significantly overlaps: the relief claimed by Mick and Angelina in these proceedings involves not only an examination of the circumstances of the 24 February 2004 transactions, but also of the respective contributions of the parties to the acquisition and improvement of McArthur Parade, which will also be an issue in the matrimonial proceedings. Were Mick and Angelina's claim limited to one to set aside the 2004 transactions, the evidence and issues would be within a relatively narrow compass which could be addressed without being revisited in the matrimonial proceedings. However, their claim for a declaration as to the beneficial interests in McArthur Parade will require an examination of the respective contributions of the parties to McArthur Parade, which will inevitably overlap the second stage of the property adjustment proceedings in the Family Court. No issue estoppel would preclude the revisitation of this matter in the matrimonial proceedings, because, if this court were to resolve the beneficial interests in McArthur Parade between Mick (and Angelina) and Bobby, by reference to their contributions to its acquisition and improvement, the Family Court would nonetheless have to consider and evaluate the contributions made by and on behalf of Bobby and Betty to the acquisition ,conservation and improvement of all their property, including but not limited to McArthur Parade, and taking into account contributions (including to other properties, and to the welfare of the family), which would not be relevant to the equity suit, in addition to those which this court would consider in the equity suit. This would result in much duplication of evidence, and some of issues for determination, which would be avoided if both proceedings were determined by the one court.
76 Only the Family Court can resolve the whole controversy without duplication of evidence and issues. The issues in the equity suit are a subset of those in the matrimonial proceedings: they are an aspect of the larger dispute already being litigated in the Family Court to which Mick and Angelina are now parties. The involvement of Mick and Angelina in the matrimonial proceedings is now inevitable as they have been joined, and would in any event be witnesses; and unless transferred by the Family Court - which no party has proposed - the s 78 application will remain part of the matrimonial proceedings and will be litigated in the Family Court. Declining to transfer the equity suit to the Family Court will not alter that position - although the Family Court might in those circumstances (but might not) adjourn the matrimonial proceedings until the equity suit has been resolved in this court, or transfer the whole of the matrimonial proceedings to this court. While both courts could (as a matter of jurisdiction) entertain and determine the whole justiciable controversy - as the Supreme Court has cross-vested jurisdiction in matters under the Family Law Act [Young v Lalic (2006) 197 FLR 27; [2006] NSWSC 18, [37]-[48]] - nonetheless no party has suggested or proposed that in this case this Court exercise its cross-vested family law jurisdiction: Betty proposes that the whole controversy be heard and determined in the Family Court, whereas Bobby, Mick and Angelina wish the equity suit to be determined in this court, and the matrimonial proceeding in the Family Court. This has the practical consequence that the larger controversy must be determined in the Family Court, because it is not open to this Court to make an order compelling the transfer of the Family proceeding to this Court, and assuming (without deciding) that this Court could - in pursuance of its implied power to protect its own processes and proceedings, and/or in exercise of equitable jurisdiction to restrain proceedings which are, according to principles of equity, vexatious or oppressive - restrain a party from prosecuting proceedings in a federal court [cf CSR Limited v Cigna Insurance Australia Ltd (1997) 189 CLR 345], no question of doing so could arise in this case, where Betty's proceedings were instituted first in time, in a clearly appropriate forum, which can resolve the whole controversy. On the other hand, it would be open to the Family Court to restrain Mick and Angelina from prosecuting the equity suit in this Court, although the power to do so would not lightly be exercised [cf Lederer & Hunt [2007] FamCA 55]. Such anti-suit injunctions are more readily granted within the confines of the federal system, than where proceedings have been issued in a foreign court and a local court [Dibeek Holdings Pty Ltd v Notaras (1997) 141 FLR 364, 373-374]. The present is a case where exactly the same issue will be litigated in two local courts: one of federal and one of State jurisdiction. It is usually inappropriate, if not vexatious, that the same issue be litigated in two different courts, and, within the federal system, it is sufficient to support an injunction that the test of inappropriateness be satisfied [Dibeek Holdings Pty Ltd v Notaras, 373, 374]. Pegasus Leasing Ltd v Cadoroll Pty Ltd (1996) 59 FCR 152 would support the grant of an injunction in the context of the instant case: in order to determine the respective extent of Bobby's and Mick's beneficial interests in the property, the evidence will be duplicated in each proceeding, and there is a real possibility that the two courts might reach different conclusions on that very question. Accordingly, in the present case, for practical purposes only the Family Court can resolve the whole controversy. The fact that one court can resolve the whole justiciable controversy and the other cannot will usually indicate that the former is the more appropriate court, although there may be exceptional cases - corresponding with those in which the federal court would as a matter of discretion decline to exercise accrued jurisdiction - in which that might not be so.
