Good Faith and Insurance Contracts

CHAPTER 1
The insurance contract uberrimae fidei
Introduction
1.01 In April 1760, a French man-of-war of 64 guns and a frigate of 20 guns audaciously raided and overran Fort Marlborough on the island of Sumatra. The attack was executed presumably in the milieu of the Seven Years’/Third Carnatic War. The Governor had foreseen the risk of an attack and considered it prudent to insure against this contingency. The seizure of the fort led to the presentation of a claim under the policy against the insurers. Six years later, the 18th-century champion of commercial law in the City of London, Lord Mansfield CJ,1 took the opportunity while presiding at Guildhall over the disputed claim to express his view on the principle of good faith, which he declared to be applicable to “all contracts and dealings”,2 although the case before him concerned only an insurance policy. 1.02 The Lord Chief Justice identified the two most common varieties of a lapse in good faith: inducing a person to enter into a contract by making false representations or by withholding information that may be of relevance to that person in deciding whether to entertain the bargain.3 Lord Mansfield thus focused on the inequities created in any contractual relationship caused by a misrepresentation or by concealment or non-disclosure. The principles of misrepresentation have remained universally applicable to all contracts in English law. To this extent, at least, the requirement of good faith is given the backing of the common law in all contracts.4 The daring hope that the prohibition of non-disclosure extended to all contracts has not been realised.5 This judgment of Lord Mansfield in Carter v Boehm is the fountainhead of many varied and often ingenious submissions, arguments, pleadings and decisions that have sought to apply, extend or abridge the duty of good faith,Page 2

“The law cannot police the fairness of every commercial contract by reference to moral principles. It frequently appears with hindsight, as in this case, that one contracting party had knowledge of facts which, if communicated to the other party, would have protected him from loss. However, subject to well-recognised exceptions, the law does not and should not undertake the reopening of commercial transactions in order to adjust such losses.”
