F.3 Common Issues and Issues of Commonality
93 I have already referred to the fact that MFI-3 contains, after many efforts, the applicants' best attempt to identify common issues and issues of commonality (and also summarises the response of the insurers to those contentions).
94 I have reached the conclusion that it is a significant overstatement to contend "substantial common issues of law and fact" remain. This is evident for several reasons.
95 First, Issues 6(b) and (c), 7, 15, 28, 38 and 42 are said to give rise to issues required to be determined, but really do no such thing. There is no real extant controversy as to these matters for the reasons identified by the insurers in MFI-3.
96 Secondly, and more generally, although it may be accepted that the policies contain policy wording that suggest common issues or a degree of commonality, to the extent that it could be done so, and those common issues were of real significance, they were addressed and resolved by the test cases.
97 It is the nature of the individual claims of group members that they arise under insurance policies - with differing terms and types and levels of cover. Looked at as a matter of substance, the real remaining disputation relates to questions of individualised causation and loss. As I will explain below, there is some utility in binding all parties to some of the answers to common issues identified during the process of argument, but this is different from identifying whether there are any common issues of real substance left to be argued and then determined at an initial trial.
98 Thirdly, reflecting the last point, there is a high degree of artificiality about the alleged commonality of some of the issues identified: without being exhaustive, it is evident that Issues 8, 9, 11, 12, 13, 14, 17, 18, at least in part, are individually fact dependent; are not the subject of an identified dispute between an applicant and an insurer; or are really questions of construction of different policies with different wordings.
99 Fourthly, it is unnecessary to go through each issue because the applicants accepted that Issues 19-23 were the high watermark of the issues of commonality requiring determination. The difficulty with Issues 19 and 20 is that although it might be said they raise questions of policy construction, it is likely that there will be a range of disparate circumstances (both temporarily and geographically) informing any answer. An answer will necessarily turn on findings as to particular facts and it is difficult to see why it would be more specific than those produced, in the circumstances of that case, by the Full Court in LCA Marrickville (at 565-566 [441] per Derrington and Colvin JJ) as referenced in MFI-3.
100 With Issues 21-23, which follow on from 19 and 20, it proposes a question as to whether a test other than a "but for" test of causation is to be applied, but the relevant causation principles are tolerably plain. As Allsop J (with whom Kiefel and Stone JJ agreed) observed in McCarthy v St Paul International Insurance Co Ltd [2007] FCAFC 28; (2007) 157 FCR 402 (at 430-431 [91]), if there are two concurrent proximate causes, "one falling within the policy, the other simply not covered by the terms of the policy", the insured may recover. Further, it is difficult to see the utility of such an abstract question when there can be no real dispute as to the accuracy of Allsop CJ's general summary of the causal inquiry in insurance law in Sheehan v Lloyds Names Munich Re Syndicate Ltd [2017] FCA 1340; (2017) 19 ANZ Ins Cas ¶62-158 (at [77]) as follows:
The causal inquiry in insurance law is directed to the proximate cause of the relevant loss or damage. This means proximate in efficiency, not the last in time: Leyland Shipping Co Ltd v Norwich Union Fire Insurance Society Ltd [1918] AC 350 at 369 per Lord Shaw; Global Process Systems Inc v Syarikat Takaful Malaysia Berhad (The "Cendor MOPU") [2011] UKSC 5; 1 Lloyds Rep 560 at 564 [19] per Lord Saville and 568 [49] per Lord Mance. A proximate cause is determined based upon a judgment as to the "real", "effective", "dominant" or "most efficient" cause: see Leyland Shipping [1918] AC at 370 per Lord Shaw; Wayne Tank and Pump Co Ltd v Employers Liability Assurance Corp Ltd [1974] QB 57 at 66 per Lord Denning MR. What is the proximate cause is to be decided as a matter of judgment reached by applying the commonsense knowledge of a business person or seafarer: see The "Cendor MOPU" [2011] l Lloyds Rep at 564 [19] per Lord Saville and 568 [49] and 576 [79] per Lord Mance. There does not need to be a single dominant, proximate or effective cause of loss or damage: McCarthy v St Paul International Insurance Co Ltd [2007] FCAFC 28; 157 FCR 402 at 430 [90]. In City Centre Cold Storage Pty Ltd v Preservatrice Skandia Insurance Ltd (1985) 3 NSWLR 739 (referred to in McCarthy 157 FCR at 430 [90]), Clarke J at 745 approached the question as follows:
… to determine in the first instance whether there is one effective cause. But, recognising that in the present case there are a number of contributing causes, I do not propose straining to isolate one if it seems to me that two or more causes operated with approximately equal effect.
101 I accept I have not dealt with each issue identified. Clearly there remain some real or potential disputes, which might be thought to have some degree of commonality. For example, as to Issues 35, 36 and 40, there is clearly an issue and the parties have been unable to agree an answer. Further there are a series of questions which have a similar theme and have elicited a common response from the insurers: see Issues 2-5, 7-9, 14, 15, 17 (linked to 25), 26-32, 37, 39, 41 and 43.
102 But the point is not whether it is possible, with effort, to divine questions with some degree of commonality or whether a class action passed through the s 33C "gateway". The reality is that following the test cases, what remains to be resolved are some potential issues which transcend individual claims, but upon close analysis I accept the insurers' submission that they cannot be properly characterised as substantial common issues of law and fact which necessitate a contested hearing.
103 Having reached these conclusions, it is necessary to turn to the application of s 33N to each class action.
