The "events" in this case
8 In the judgments identified above, I determined three interlocutory applications, each filed on 2 March 2017 essentially seeking summary judgment or alternatively that the statement of claim be struck out. The applications were filed by:
(1) the first to third respondents ("CBC respondents");
(2) the fourth respondent ("Mr Emanuel"); and
(3) the fifth to seventh respondents ("Raven respondents"),
respectively.
9 The result of the applications was that the statement of claim was substantially, but not entirely, struck out and the applicant ("Deep Investments") was granted a limited liberty to re-plead its case. The fact that the statement was not struck out in its entirety reflected the possibility that Deep Investments may be able to plead viable causes of action by reference to allegations not struck out, not that it had already done so. On any view, this was a substantial success for the respondents.
10 Thus, I do not accept the submission made on behalf of Deep Investments that the respondents' success was limited to relatively minor pleading points. A particularly important element of the success of the CBC and Raven respondents was the striking out of the claims based on breach of fiduciary duty in connection with the trading of National Australia Bank Limited ("NAB"), Billabong International Limited ("Billabong") and Boart Longyear Limited ("Boart Longyear") shares. Another important element of all of the respondents' success was the striking out of the claims based on breach of fiduciary duty in connection with the Wilson documents, with leave granted to re-plead.
11 On the other hand, the respondents' claims for summary dismissal were refused. Consequently, the respondents have sought leave to appeal from my decision.
12 I accept Deep Investments' submission that the claims for summary dismissal dominated the hearing of the applications. The effect of the strike out of the claims based on breach of fiduciary duty in connection with the trading of NAB, Billabong and Boart Longyear shares, without leave to re-plead, was that the CBC and Raven respondents succeeded in this aspect of their summary dismissal claim, on the basis of an estoppel of the kind identified in Port of Melbourne Authority v Anshun Pty Ltd [1981] HCA 45; (1981) 147 CLR 589 ("Anshun estoppel"). However, otherwise, the Raven respondents failed on their res judicata and issue estoppel arguments, and all respondents failed on their arguments for summary dismissal in relation to the claims based on the Wilson documents.
13 Taking into account the dominance of the unsuccessful summary dismissal claims in the conduct of the applications, in my view, despite the respondents' success in striking out substantially the whole of the statement of claim, the parties should each bear their own costs of the various applications.
14 In addition, I make the following observations concerning the parties' submissions.
