Marsh's argument
8Komatsu's liability at the suit of Kalgoorlie in the Western Australian proceedings potentially fell within one or other of two sections of the Broadform liability policy in question, issued to Komatsu by the insurers for the period of 12 months commencing on 30 September 2003. Section A of the policy potentially responded to the negligent servicing claim and was subject to the first and second exclusions referred to in Komatsu's statement of claim. Section B of the policy potentially responded to both the product liability claim and the negligent servicing claim and was subject to the third exclusion referred to in Komatsu's statement of claim.
9Komatsu alleges in these proceedings that each of the exclusions was included in the policy as a consequence of Marsh's breach of duty. Marsh contended on this application that whilst it was possible that Komatsu may either win or lose on all three of the contested exclusion clauses in that context, it was also possible that Komatsu may establish a breach of duty by Marsh in respect of less than all three of the exclusion clauses.
10In the Western Australian proceedings, the insurers, who had declined indemnity, were joined by Komatsu on a cross-claim but Marsh was not joined to the proceedings in any way. Komatsu has only sued Marsh in the current proceedings in the Court. However, several other parties were joined to the Western Australian proceedings.
11In early 2009 the Supreme Court of Western Australia referred the matter to mediation. The orders made included an order that the mediation be conducted on a confidential basis and limited the use that could be made of the mediation communications and documents in other proceedings. At a later point, Komatsu also executed a mediation agreement, in which it agreed to keep mediation related communications confidential, subject to some exceptions, which included disclosure required by law. Marsh contends in this case that the significant impediment to discovery is the specific order of the Supreme Court of Western Australia, rather than the terms of the mediation agreement.
12Marsh made submissions to Komatsu for use by Komatsu in discussions with the insurers at the mediation, to the effect that the first exclusion had not been agreed between it as placing broker and the insurers, that the inclusion of sub-paragraph (b) of the first exclusion was recorded in the issued policy by common mistake, and as to why the insurers would be in breach of s 14 of the Insurance Contracts Act 1984 if they were to rely upon the first exclusion.
13The result of the mediation was that Komatsu settled with Kalgoorlie for a payment to Kalgoorlie of $10M. The settlement deed provides no details of what claims that sum was paid to settle or the amounts in respect of the individual claims. Komatsu also settled with its insurers and the other parties upon the basis of a payment to Komatsu of $5M from the insurers, $2.5M from Komatsu Germany which manufactured the shovel, and nothing from Tyco, a third party that supplied the fire suppression system for the shovel. Although the difference is $2.5M, Komatsu sues Marsh for $2.1M in these proceedings after certain adjustments that are unimportant for present purposes. The sum of $2.1M has been referred to below as the "net contribution". At paragraph 21 of its statement of claim in these proceedings, Komatsu alleges that "the net contribution by [it] to the [settlement] was, in the circumstances ... reasonable".
14Accordingly, the claim for damages brought by Komatsu for damages against Marsh is based upon the principles enunciated by the High Court in Unity Insurance Brokers Pty Ltd v Rocco Pezzano Pty Ltd [1998] HCA 38; (1998) 192 CLR 603. Harrison AsJ referred to this case in her reasons for judgment at [25] - [27] as follows:
"[25] Both parties referred to Unity Insurance Brokers Pty Limited v Rocco Pezzano Pty Limited (1998) 192 CLR 603. The facts in Unity Insurance are similar. An insurance broker arranged an industrial special risks policy but negligently failed to disclose the insured's claims history fully to the insurer. After the insured's premises were damaged by fire, the insurer refused to pay the full amount which would have been payable under the policy if not for the non-disclosure. The insured brought proceedings against the insurer and the broker in which the insurer paid a lesser sum by way of compromise. The insured claimed the balance from the broker.
[26] As to the approach that should be taken in claims against an insurance broker it was outlined by Gummow J at [67] - [68] where his Honour stated:
'[67] The primary judge held (in my view, correctly) that it might reasonably be supposed to have been contemplated at the time of the engagement between the appellant and the respondent "that a failure to exercise due care and skill in the course of disclosing the [respondent's] prior claims history of the intended insurer might result in a later refusal, on the part of the insurer, to admit liability in respect of a claim made under a policy of insurance obtained in those circumstances". I also would accept that it was within the reasonable contemplation of the appellant and the respondent that a serious possibility or not unlikely result of the appellant's breach of its obligations with respect to the brokerage of the policy was that, by the operation of s28 of the Act, there would be a shortfall for the respondent in the amount which otherwise would have been recoverable under a secure policy.
[68] As I have indicated, the question then becomes one, in the events that have happened, of finding the amount which represents that shortfall. I would not accept that, in the above sense, it was within the reasonable contemplation of both the appellant (as broker) and the respondent (as insured) that, as between them, this amount would be fixed by reference to a settlement, which was reasonable as between the respondent and the insurer, of a claim made upon and rejected by the insurer. The reasonable contemplation spoken of in the rule in Hadley v Baxendale is that of both parties and the time at which that is assessed is the time when they made the contract. Here, as in other fields of law, hindsight may mislead. It was not within the reasonable contemplation of the broker and the insured that the measure of the liability of the broker to the insured would be determined by the conduct of parties over which the broker had no control, namely the insured and the insurer. The broker had not undertaken to indemnify the insured against any shortfall upon a settlement of litigation between the insured and the insurer.'
[27] Also Hayne J stated at [128] - [130]:
'[128] In my view, however, the several considerations which I have mentioned, especially the need to encourage settlement of disputes, suggest that a settlement of the dispute between insured and insurer should be given more significance as between insured and broker than simply identifying an amount which may limit the amount of damages recoverable by the insured from the broker for the broker's breach of duty. They are considerations that suggest that the damages recoverable by the insured should be fixed as the difference between what the insured recovered under the settlement (if it was reasonable) and what would have been recovered under the policy which the broker ought to have arranged (together, no doubt, in an appropriate case, with any other costs or expenses incurred by the insured as a result of the broker's breach and taking account of any extra premium that would have been payable). Whether such a rule would, or may, work injustice to the broker is much affected by what is meant by a "reasonable" settlement of the dispute between insured and insurer and it is to that subject that I now turn.
[129] Whether the compromise of a claim was reasonable must be judged objectively, not subjectively. Thus whether a party to litigation has received advice to settle may be important in deciding whether that person's conduct in settling the case was reasonable but, standing alone, the fact that a litigant was advised to settle at a particular figure reveals little or nothing about whether the settlement reached was reasonable. This is not to say that evidence may not be led that such advice was given and adopted; it may. But evidence of that kind does not conclude the issue. What will usually be much more important is the reasoning that supported the advice that was given for that will ordinarily reveal why it was thought reasonable to compromise the claim as it was.
[130] Next, the question whether the settlement was reasonable must be judged by reference to the material the parties had available to them at the time the compromise was reached. It is not to be judged according to whether material which was obtained later shows that the opposite party could or could not have prosecuted or defended the claim successfully but according to the assessment which could properly be made at the time of settlement of the chances of success or failure.' (footnotes omitted)."
15Marsh contended in these proceedings that in terms of the first limb of Pezzano , where one is concerned with a liability said to have been established by the payment of money to settle multiple claims:
1.Where there are a number of claims that have been settled by the payment of money, and where there is a potentially different policy response to each claim, it is also necessary to determine what claim or claims the promise to pay money related to and, if the promise is made to settle multiple claims, precisely how the settlement sum is said to be attributable to each: Enterprise Oil Ltd v Strand Insurance Co Ltd [2007] EWHC 58 (Comm) at [170] - [172]; AIG Europe (Ireland) Ltd v Faraday Capital Ltd [2007] 1 All ER (Comm) 527 at [68] - [71]; Kernaghan v Corrections Corporation of Australia Staff Superannuation Pty Ltd (No 2) [2007] FCA 1040 at [14] - [21].
2.Following that exercise, it is then necessary to establish that the agreement to make payment by way of settlement is a "relevant" liability for the purposes of the liability insurance. Where liability is sought to be established by an agreement to pay in a settlement, at least where the settlement is reached after the insurer has declined indemnity, it is at least necessary for the insured to prove that the settlement said to give rise to the liability was objectively reasonable: Edwards v Insurance Office of Australia (1934) 34 SR (NSW) 88; BNP Paribas v Pacific Carriers [2005] NSWCA 72 at [13], [187].
3.The documents to which Marsh sought access were identified in categories described in a letter dated 1 March 2010 from Wotton + Kearney to Baker & McKenzie. Categories 1.4 and 1.5 were the only categories with which her Honour was concerned and were as follows:
"1.4 All documents recording, referring or relating to the mediation between the parties to the Western Australian Claim, including the position papers, mediation agreement, settlement terms sheet, etc.
1.5 All documents recording, referring or relating to legal advice received from Komatsu in relation to the Western Australian Claim and the settlement of the claim."
4.Marsh contended that the claim for privilege maintained over documents in these categories pursuant to ss 118, 119 or 131(1) of the Evidence Act had been lost by operation of ss 122(2), 131(2)(g) or 131A of that Act. Specifically, Marsh claimed that:
- Category 1.4 documents could be the subject of a claim for 'without prejudice' privilege under s 131(1) and 131A but that s 131(2)(g) operated to defeat the claim. In addition, Marsh contended that to the extent that the orders of the Supreme Court of Western Australia operated as an impediment to Komatsu producing the documents, it was entitled to an order requiring Komatsu to take all reasonable steps to remove the impediment.
- Category 1.5 documents could be the subject of a claim for privilege under ss 118 and 119 but that Komatsu had waived the privilege pursuant to s 122(2).
