Court of Appeal decision applying the duty of pre-contractual disclosure in a marine context, illustrating the materiality of pending criminal proceedings against the insured’s principals.
The litigation concerned a marine hull and machinery policy on a vessel owned by interests connected with the claimant North Star Shipping Ltd. The policy was placed in the London market with Sphere Drake and other insurers through a chain of brokers. The vessel suffered a loss giving rise to a claim under the policy.
The insurers declined the claim and sought to avoid the policy on the ground of pre-contractual non-disclosure and misrepresentation. The matters which they said ought to have been disclosed included pending or threatened criminal proceedings against individuals connected with the management of the insured and its associated companies, allegations of fraud or other dishonesty in connection with the business of the owners, and aspects of the loss record of related vessels which had not been brought to the underwriters’ attention at placement.
At first instance the judge concluded that several of the matters had been material and had not been disclosed, and that the insurers had been entitled to avoid. The insured appealed, contending that the matters in question were either not material in the Pan Atlantic sense, or were within the underwriters’ actual or constructive knowledge, or had not in fact induced the underwriters to write the risk on the terms agreed.
The Court of Appeal was therefore required to apply the established two-stage test of materiality and inducement to a body of evidence which included expert underwriter testimony, contemporaneous broker notes and the placing slip itself. The case is one of the fuller modern examples of the application of those principles in a marine hull context.
The principal issues were whether the matters relied upon by the insurers were material in the Pan Atlantic sense, namely whether they would have influenced the judgement of a prudent underwriter in deciding whether to take the risk and on what terms; whether the matters had been disclosed in substance even if not in terms, or had been within the underwriters’ actual or constructive knowledge such that disclosure was not required; and whether the non-disclosure had in fact induced the actual underwriters to write the policy on the terms agreed.
A subsidiary issue concerned the materiality of allegations or pending criminal proceedings against the moral hazard side of the risk, an area in which case law was developing rapidly during the early 2000s. The question was whether mere allegations, falling short of conviction, could be material to a prudent marine underwriter.
The Court of Appeal dismissed the insured’s appeal. It accepted that pending criminal proceedings and serious allegations of dishonesty against individuals connected with the management of an insured shipowner were capable of being material to a prudent marine underwriter, since they bore directly on moral hazard. On the evidence, including the testimony of underwriter witnesses, the matters had not been disclosed and they had been material.
The court also accepted that the underwriters had been induced to write the risk on the terms agreed by the placing presentation as it had in fact been made. An inference of inducement was readily drawn from the materiality of the matters concerned and from the contemporaneous evidence of the underwriting decision. The insured’s contention that the underwriters had constructive knowledge of the matters in question, by reason of their general experience of the market, was rejected.
The avoidance of the policy was upheld. The court took the opportunity to reiterate that the duty of disclosure operates by reference to a fair presentation of the risk as a whole, and that piecemeal disclosure of fragments does not necessarily discharge the duty where the cumulative significance of the matters concerned has not been brought home to the underwriter.
Pending criminal proceedings and serious allegations of dishonesty against individuals connected with the management of an insured are capable of being material to a prudent underwriter under the Pan Atlantic test, particularly where they bear on moral hazard. Whether such matters were in fact material and induced the actual underwriter on risk are questions of fact to be determined on the evidence in each case.
The duty of disclosure requires a fair presentation of the risk as a whole. An insured cannot rely on fragmentary disclosure to discharge the duty where the cumulative significance of the matters has not been conveyed to the underwriter in a way reasonably calculated to bring it to their attention.
North Star Shipping is the leading modern Court of Appeal authority on the application of the Pan Atlantic test in a marine hull context, and is regularly cited in disputes concerning moral hazard disclosure across non-marine commercial classes. The decision foreshadowed the statutory formulation of the duty of fair presentation in section 3 of the Insurance Act 2015, which requires the insured to make the disclosure in a manner which would be reasonably clear and accessible to a prudent insurer.
For brokers, the case underlines the importance of disclosing not only convictions but also pending criminal proceedings and serious investigations involving the insured’s principals, even where the insured maintains its innocence. The duty is to make the underwriter aware of the existence of the matter; the underwriter is entitled to decide what weight to give to it.
For insureds, North Star Shipping is a reminder that allegations of dishonesty connected with the management of the business are highly likely to be material in any commercial class which depends substantially on trust in management, including marine, financial lines, fidelity and crime cover. Failure to disclose such matters risks avoidance of the policy ab initio or, after 12 August 2016, the application of proportionate remedies under section 8 of the Insurance Act 2015.
