Crane v Hannover Ruckversicherungs- Aktiengesellschaft & Anor

In reinsurance, contractual formation depends on an objective analysis of offer, acceptance and intention to contract. Scratching a Lloyd’s slip is common practice, but it is not conclusive. A representation about underwriting requirements does not ordinarily imply a representation that those requirements will be followed in every future case. The court construes the representation objectively and will not enlarge it by importing unstated assumptions about how historical losses must be adjusted or how many years of loss history must be used. For non-disclosure, the reinsured need not provide the reinsurer’s own assessment of matters equally known to both parties where the reinsurer is in as good a position to assess them. Avoidance requires materiality and inducement. The Syndicate failed to prove actionable misrepresentation or non-disclosure and was not entitled to avoid the relevant reinsurance contracts.

The claimant, representing the underwriting members of Syndicate 53 at Lloyd’s, sought declarations that it had validly avoided three 1998 Mainframe Carve-out retrocessions against Hannover. The alleged grounds were misrepresentation and non-disclosure concerning Legion’s underwriting methods, the relative strictness of the Mainframe and Cessions Accounts, and Hannover’s underwriting and claims audits.

The court also had to determine when the reinsurance contracts were concluded and whether a sample of Legion files supported the claimant’s inferences. The central issues were the objective meaning of the alleged representations, their materiality and inducement, and whether Hannover had to disclose information which the Syndicate could assess for itself.

1. Outcome. The Syndicate’s three final complaints failed. It was not entitled, as against Hannover, to avoid the relevant 1998 Mainframe Carve-outs.

2. Contract formation. The usual Lloyd’s practice is that presentation of a slip constitutes an offer and scratching constitutes acceptance. That practice is not uniform. The court must determine objectively what was offered and accepted, and whether the parties intended to contract. Here, the Syndicate made offers which were accepted when Hannover’s order was notified, on or shortly before 10 December 1998. The later scratching of final slips recorded the participating reinsurers and percentages rather than creating the contracts.

3. Representations. Objectively, the renewal proposals represented only that the Mainframe underwriting requirements required use of prospective insureds’ actual loss histories in calculating expected losses and required calculation by a prescribed methodology. They did not represent that Legion would invariably comply with those requirements or that the requirements were immutable. The reference to five years’ loss history was qualified by the word generally. The materials did not specify that historical losses could never be adjusted or that less than five years could never be used.

4. Falsity and inducement. The matters relied upon did not establish falsity. Adjusting loss histories, removing non-renewing accounts, making upward adjustments, or using permitted underwriting-box arrangements was not inconsistent with the limited representations. Errors in individual calculations did not prove that Legion was not ready and willing to comply with the RPG. The representations were also too vague to be material without knowing how the histories or methodology were to operate. In any event, Mr Crane was not induced by them: if they had mattered, he would have sought the RPG or further explanation before matching Clarendon’s rates.

5. Non-disclosure. The relevant obligation was to disclose every material circumstance known or deemed known to the reassured. But the reassured need not offer the reinsurer its own opinion on matters equally known to both and capable of assessment by the reinsurer. The renewal proposals described the loss-rating approach, heterogeneous business and use of TPAs. The Syndicate was in as good a position as Hannover to assess those matters. The audit reports therefore did not have to be disclosed on the case advanced. The reporting documents did not show that Hannover knew or ought to have known of actionable departures from its requirements.

6. Evidence. The 27-file sample was not random and lacked a valid basis for extrapolation to the 71-risk account. Its premium proportion did not establish representativeness. Later events also could not, without more, prove Legion’s state of mind at the contract date.
