Fraud condition in insurance policy
Whether applies to dishonest statement depends on how it is interpreted.
The DC Merwestone litigation occupies an important place in the modern law of insurance fraud. Although it began as a marine hull and machinery dispute, it developed into a leading authority on the distinction between a fraudulent claim and a dishonest statement made in support of an otherwise valid claim. The issue was considered at three levels of the English courts: the Commercial Court, the Court of Appeal and the Supreme Court.
The significance of the case lies in the development of the law across those three decisions. At first instance and in the Court of Appeal, the courts held that the use of a false statement in support of the claim was sufficient to forfeit the claim in its entirety. The Supreme Court took a different view, holding that a dishonest but immaterial statement, described as a ’collateral lie’, does not convert a valid claim into a fraudulent one.
That distinction is now central to the analysis of fraudulent statements and claims and remains relevant in the context of the Insurance Act 2015 (2015 Act).
Introduction
English insurance law has long adopted a strict approach to fraud. An insured who fabricates a claim, or who dishonestly exaggerates a genuine claim, is not entitled to recover. The rationale is clear; the law does not permit an insured to attempt to obtain more than it is entitled to under the contract.
The more difficult question arises where the insured has suffered a genuine loss and is in principle entitled to be indemnified but makes a false statement in support of the claim during the claims process and prior to the commencement of litigation. Prior to the Supreme Court’s decision in DC Merwestone, the common law had developed in a way which treated certain such statements as ’fraudulent devices’, capable of defeating the whole claim.
The Supreme Court in the DC Merwestone reconsidered that approach and established a more precise boundary between genuine claims tainted by dishonesty and claims which are fraudulent in substance.
The background facts
In January 2010, after loading a cargo of scrap steel at Klaipeda and sailing for Bilbao, the DC Merwestone suffered a substantial ingress of water which flooded the engine room. The main engine was damaged beyond repair. The owners claimed approximately €3.24 million under the policy.
The immediate cause of the flooding was traced to the emergency fire pump system. In freezing conditions at Klaipeda, the crew had used the system to clear ice from the hatch covers. When that operation ended, they failed to drain the pump and close the sea inlet valve. Seawater remained in the system, froze, and caused damage to the pump casing and filter arrangement. Once the vessel sailed and the ice melted, seawater entered the bow thruster room.
The water then passed into the duct keel and from there into the engine room because cable apertures in the relevant bulkheads had not been properly sealed. The flooding was exacerbated by the inability of the vessel’s pumping arrangements to deal effectively with the ingress.
Accordingly, the casualty was caused by a combination of crew negligence, damage to the emergency fire pump system, ineffective sealing of bulkhead penetrations and pumping deficiencies.
During the claims process, the Owners, as Assured, had informed the Insurers that the bilge alarm had sounded at about noon on 28 January, and the crew could not investigate because the ship was rolling heavily in bad weather. However, this was not true.
The principal dispute was not whether the casualty had occurred, but whether the resulting loss fell within the policy and whether the Owners had forfeited the claim by presenting the lie about the bilge alarm timing.
The legal framework
The relevant area of dispute regarding the fraud allegation was Underwriters’ argument that the claim was forfeit because of dishonest statements made during the claims process regarding the timing of the bilge alarm system.
The legal issue was whether such a statement, if dishonest or recklessly made, was sufficient to defeat the claim even if the claim itself was otherwise valid.
Issues to be decided
The principal issues before the courts can be summarised as follows:
1. Was the bilge-alarm narrative false and, if so, was it fraudulent?
2. If it was fraudulent, did that falsehood forfeit the claim even though the Owners had in fact suffered a covered loss?
The Commercial Court decision
At first instance, Popplewell J held that the Owners had established a valid claim under the policy. The loss was found to have been proximately caused by the fortuitous ingress of seawater and was therefore covered under the policy. The Court also accepted the Owners’ case on quantum, including the reasonableness of replacing the damaged engine with a new one.
Nonetheless, the claim failed because of the judge’s finding that the statement concerning the noon bilge alarm was a reckless untruth advanced to support the claim. He held that it was intended to improve the Owners’ prospects of obtaining payment by presenting the casualty as one more readily attributable to crew negligence than to any failing that might be laid at the door of the Owners or managers.
Applying the authorities as he understood them, and in particular the line of reasoning associated with fraudulent devices, Popplewell J concluded that the dishonest statement was sufficient to forfeit the whole claim. He expressly recognised that the result was severe given that the underlying loss was genuine and covered but was bound by precedent.
The Court of Appeal decision
The Court of Appeal dismissed the Owners’ appeal. It agreed that the bilge alarm statement was a false representation made at least recklessly and intended to promote the success of the claim.
The Court also upheld the broader legal principle that the fraudulent claims rule extended beyond wholly fabricated or dishonestly exaggerated claims to include the use of fraudulent means or devices in advancing an otherwise valid claim. It accepted that public policy and deterrence justified that approach. On that footing, an insured was not to be permitted to regard dishonesty in the claims process as a risk-free tactic.
The Court of Appeal, therefore, confirmed that the Owners had forfeited the claim, notwithstanding that the loss itself fell within the policy.
The Supreme Court decision
The Supreme Court allowed the appeal by a majority and altered the legal position.
The Supreme Court accepted the established principle that where a claim is fabricated or dishonestly exaggerated, the entire claim fails. However, it declined to extend that principle to what it described as a ’collateral lie’, a dishonest statement made in support of a claim which, once the facts are properly established, turns out to be irrelevant to the insured’s right to recover.
The Court held that the untruth in the DC Merwestone was a ’collateral lie’. The bilge alarm narrative was dishonest, but it did not alter the fact that the Owners had suffered a covered loss and were entitled to recover under the policy. The success of the claim did not depend upon the truth of the statement.
The Supreme Court, therefore, drew a distinction of principle between:
1. a fraudulent claim, in which the insured seeks to obtain something to which it is not entitled and
2. a valid claim which is supported by a dishonest but immaterial statement.
Only the former category engages the fraudulent claims rule so as to defeat the claim in full.
The majority considered that to apply forfeiture to an immaterial lie would go beyond the proper rationale of the rule. The lie remained relevant to credibility and could carry procedural and forensic consequences, but it did not justify loss of the substantive entitlement itself.
In his dissenting judgment, Lord Mance acknowledged that in the relatively rare case, such as this one, where the insured pursued a claim to trial and was found after the event to have had a sound claim, it might seem harsh that the whole claim was dismissed. Nonetheless, in his view, a person who used fraudulent devices in the context of the good faith relationship between insurer and insured ’deserves no real sympathy.’ Lord Mance suggested that insurers might wish to provide expressly for the effect of fraudulent devices on the claims process in their policies.
The Insurance Act 2015
The case remains important in the context of the 2015 Act which came into force after the casualty.
Section 12 of the 2015 Act, which applies to insurance contracts entered into on or after 12 August 2016, sets out the insurer’s remedies where the insured makes a fraudulent claim. In such circumstances, the insurer is not liable to pay the claim, may recover sums already paid in respect of it, and may by notice treat the contract as terminated from the time of the fraudulent act.
The 2015 Act, therefore, confirms the strict consequences of making a fraudulent claim. It does not, however, fully resolve the boundary between a genuinely fraudulent claim and a valid claim supported by dishonest but legally irrelevant statements. That distinction remains informed by the Supreme Court’s ruling in DC Merwestone.
The relationship between the case and the statute can therefore be stated simply. The 2015 Act prescribes the remedies for fraudulent claims. DC Merwestone helps define when those remedies are engaged.
Industry response
As a result of DC Merwestone, a number of insurers incorporated fraud conditions in their insurance policies. Whether such provisions achieve the intended purpose is likely to depend on how they are interpreted by the Court.
In Malhotra Leisure Ltd -v- Aviva Insurance Ltd [2025] EWHC 1090 (Comm), the insurer denied a claim arising out of a flood at a hotel during the Covid-19 lockdown. It contended that the assured had deliberately caused the flood and had pursued the claim dishonestly, including by making dishonest statements in the presentation of the claim in breach of a fraud condition in the policy.
The Court found that there was no dishonesty in the presentation of the claim. However, in obiter comments, the Court stated that it was not any fraudulent statement that entitled the insurer to refuse the claim under the fraud condition. Rather, the statement had to be one that was made to assist in persuading the insurer to pay the claim. The wording of the fraud condition was consistent with a requirement that any statement significantly improved the insured’s prospects of recovery.
Therefore, express fraud conditions in insurance policies may not be a complete answer to DC Merwestone.
Conclusion
The Supreme Court decision in DC Merwestone is a leading authority on the modern law of fraudulent claims.
Its lasting contribution is the distinction it draws between a claim that is fraudulent in substance and a claim that is valid but accompanied by a dishonest embellishment. The former still fails in full. The latter does not necessarily do so.
In that respect, the case marks an important development in the balance struck by English law between the deterrence of fraud and the preservation of valid contractual entitlements.
For marine insurers, assureds and those involved in claims handling more generally, DC Merwestone remains a key case. Its significance has not diminished with time. If anything, it has increased as the decision now needs to be considered alongside the statutory framework introduced by the 2015 Act.
