D.3.3 Consideration
48 It is necessary to recall four important findings made in the principal judgment:
(1) the Side C Coverage Intention is defined at J[80] in the following terms:
… the parties intended to execute the 2016-17 Policies on the basis that Side C cover was not subject to a sub-limit of $10 million, but was in fact equal to the Limit of Liability for Section 1B cover provided for by each of the 2016-17 Primary, the 2016-17 1XS and the 2016-17 2XS, meaning that the 2016-17 Policies collectively provided Side C cover of up to $50 million.
(2) all parties accepted, consistent with what is revealed in the authorities, that the slip method of placing insurance, by signing the MRC and stating the proportion of the risk that the underwriter is prepared to subscribe, results in the conclusion of separate contracts between the insured and each subscriber of the slip (J[29(5)]);
(3) hence, while there may only be one primary policy and three excess polices, there are in fact nineteen separate contracts reflected by the 2016-17 Policies (J[29(7)]); and
(4) in light of these findings, it was necessary to assess the intention of each individual insurer: cf Towry Law plc v Chubb Insurance Co of Europe SA [2008] NSWSC 1352 (at [66] and [138] per McDougall J).
49 These findings are integral to the question of relief. That is because the common intention as defined must be understood in the context of how it applies to the specific contract between Quintis and each Relevant Insurer and the rights and obligations created by that contract. As was made clear in General Reinsurance Corporation v Forsakringsaktiebolaget Fennia Patria [1983] QB 856 (at 864 per Kerr LJ, with whom Slade and Oliver LLJ agreed), each subscribing insurer becomes bound to the extent of its proportion of the risk when it accepts its individual contract. Hence, while I have found that Argo and Vibe were operating with the intention that the layers to which they were subscribing provided Side C cover up to the Limit of Liability for Section 1B cover, and that Quintis' overall insurance programme provided for $50 million in Side C Cover, the manifestation of that intention as it applied to their contract with Quintis was to provide a set proportion of cover at a specific layer.
50 While no party referred at length to these provisions, what I have said is consistent with what appears under in the MRC under the Security Details heading:
SECURITY DETAILS
INSURER'S LIABILITY:
(Re)insurer's liability several not joint
The liability of a (re)insurer under this contract is several and not joint with other (re)insurers party to this contract. A (re)insurer is liable only for the proportion of liability it has underwritten. A (re)insurer is not jointly liable for the proportion of liability underwritten by any other (re)insurer. Nor is a (re)insurer otherwise responsible for any liability of any other (re)insurer that may underwrite this contract.
The proportion of liability under this contract underwritten by a (re)insurer (or, in the case of a Lloyd's syndicate, the total of the proportions underwritten by all the members of the syndicate taken together) is shown next to its stamp. This is subject always to the provision concerning "signing" below.
…
Proportion of liability
Unless there is "signing" (see below) the proportion of liability under this contract underwritten by each (re)insurer (or, in the case of a Lloyd's syndicate, the total of the proportions underwritten by all the members of the syndicate taken together) is shown next to its stamp and is referred to as its "written line".
Where this contract permits, written lines, or certain written lines, may be adjusted ("signed"). In that case a schedule is to be appended to this contract to show the definitive proportion of liability under this contract underwritten by each (re)insurer (or, in the case of a Lloyd's syndicate, the total of the proportions underwritten by all the members of the syndicate taken together). A definitive proportion (or, in the case of a Lloyd's syndicate, the total of the proportions underwritten by all the members of a Lloyd's syndicate taken together) is referred to as a "signed line". The signed lines shown in the schedule will prevail over the written lines unless a proven error in calculation has occurred.
Although reference is made at various points in this clause to "this contract" in the singular where the circumstances so require this should be read as a reference to contracts in the plural.
51 Indeed, I do not think that it is a precondition to the award of relief, as the second respondent suggests, to find that Argo and Vibe intended to provide Side C cover irrespective of the position of the other insurance contracts (although there is no direct evidence bearing on this question one way or another). To refuse relief on the basis that it has not been found that the other insurers to the 2016-17 Policies held the Side C Coverage Intention is to confuse the 2016-17 Policies, which record the bundle of contracts, with the individual contracts themselves, and the bilateral rights and obligations created under these contracts.
52 Two factors have caused me pause before coming to the conclusion that rectification is available in the current circumstances.
53 First, is the reality in which Argo and Vibe now find themselves (unsupported by co-insurers and, in the case of Vibe, by a complete underlying first excess layer) and the need to insert terms into the 2016-17 Policies which are inconsistent with the Side C Coverage Intention being commonly held by all parties. In this respect, the first and third respondents sought to draw support from the following passage of Campbell JA's reasons in Franklins (at 711 [450]):
It is the document as a whole that is rectified, and the point of the exercise is that, once rectified, the document will not be contrary to the common intention of the parties to the document. Thus if a particular change to some words will result in some other words of the document operating in a different way, rectification will be justified only if that different operation of those other words is shown to be in accordance with the common intention of the parties.
(Emphasis added).
54 However, upon examination, I do not think these remarks assist Argo or Vibe's case. Any suggestion that the form of relief cannot be reconciled with the Side C Coverage Intention not being commonly held by all parties must acknowledge the contractual structure at play. This is because, although the proposed terms do isolate Argo and Vibe, they do so consistently with the Side C Coverage Intention found, as it applies to the contracts between Quintis and these insurers. That is, these terms simply bring the 2016-17 Policies to a form that reflects the contractual intention of these insurers to indemnify a set proportion of risk at a certain layer (but militates against the intention being held by others).
55 In my view, and applying what was said by McLeish, Niall and Sifris JJA in Queenfield (at [87]), I do not see how giving effect to the "clear common intention" of Quintis and these insurers rewards one party for its mistake and harms the other party for that very same mistake. What matters is that the intention is given effect (see [28]-[31] above) and that the order for rectification, "once made, relates back so that the rights of the parties are treated as having always been in accordance with the contract as so rectified" (emphasis added): Franklins (at 750 [644] per Campbell JA, with whom Allsop P and Giles JA agreed); see also Simic v New South Wales Land and Housing Corporation [2016] HCA 47; (2016) 260 CLR 85 (at 117 [103]-[104] per Gageler, Nettle and Gordon JJ) and Lloyds TBS Bank plc v Crowborough Properties Ltd [2013] EWCA Civ 107 (at [62]-[64] per Lewison LJ, with whom Rimer and Mummery LJJ agreed).
56 Secondly, is the submission that the availability of funds from co-insurers on the same layer would give these insurers the opportunity to seek to buy out a risk where the quantum was uncertain (i.e. a claim against an insured that could produce a range of results) at a higher price than they would wish to if they were using their funds alone. If this were true, placing Argo and Vibe in a position where they no longer have such an opportunity would be to alter the bargain entered into. These submissions may have had force at the initial trial, but the fact is that these insurers led no evidence whatsoever in support of this proposition even when it became apparent that there may be mixed findings as to the holding of the Side C Coverage Intention as it applies to the contracts between Quintis and the various insurers. Further, as I have outlined above, Argo and Vibe expressed no desire to apply to reopen or to be heard orally on the question of relief. In making this remark, I am not reversing the onus of proof, but highlighting that the concept of the "comfort of co-insurance", without any supporting lay or expert evidentiary foundation, is a somewhat nebulous and speculative one.
57 In these circumstances, I am not of the view that to order rectification in the circumstances would, on the evidence, be fashioning a bargain that the parties did not strike or giving effect to an agreement that goes beyond that which the parties intended: see Muriti (at [137] per White J). Nor is there a danger, to adopt the words of Campbell JA in Franklins (at [459]), of "imposing on a party a contract which he did not make". All that rectification is doing in these circumstances is bringing the policy, as the document recording the contracts of insurance, into line with the common intention of the parties. Indeed, this is not a situation where there was in fact no common intention between the parties, a common misunderstanding, or an oversight of a particular matter: see, eg, Club Cape Schanck Resort Co Ltd v Cape Country Club Pty Ltd [2001] VSCA 2; (2001) 3 VR 526 (at [12] per Tadgell JA). Nor is this a case in which the Court would be supporting a doctrine of rectification pro tanto: cf KPMG v Network Rail Infrastructure Ltd [2007] EWCA Civ 363; [2008] P&CR 11 (at 199 [31]-[33] per Carnwath LJ). It is a situation in which parties entered into bilateral contracts with a common intention to provide a specific proportion of cover at a specific layer.
58 Indeed, consistent with the rationale articulated above, it would be against conscience to allow the 2016-17 Policies to stand in their current form. As Campbell JA noted in Franklins (at 710 [444], with whom Allsop P and Giles JA agreed):
… equity focuses on what it is unconscientious for a party to assert about the contract. The rationale is that it is unconscientious for a party to a contract to seek to apply the contract inconsistently with what he or she knows to be the common intention of the parties at the time that the written contract was entered. In other words, when a plaintiff succeeds in a claim for rectification, the plaintiff is found to have been justified in effect saying to the defendant "you and I both knew, when we entered this contract, what our intention was concerning it, and you cannot in conscience now try to enforce the contract in accordance with its terms in a way that is inconsistent with our common intention."
(Emphasis added).
59 Therefore, despite the novel aspects of the way in which the claim for rectification has played out, given that the 2016-17 Policies represent distinct contracts between Quintis and Argo and Quintis and Vibe, the equity should run.
60 With these issues now clarified, it is necessary to turn to the precise form of relief.
