George Wimpey UK Ltd v VI Construction Ltd: CA 3 Feb 2005

A land purchase contract had been rectified by the judge for unilateral mistake. A factor had been dropped from a formula for calculating the price.
Held: The judge’s conclusion that the circumstances existed to allow a rectification was incorrect. The appeal was allowed: ‘There is, as it seems to me, a paradox in the notion of what an honourable and reasonable person would do in the context of an arm’s-length commercial negotiation. This is a context in which honour (or honesty) and rationality (or reasonableness) are frequently not on speaking terms.’
The court continued to consider the place of mistake: ‘The phrase ‘honest and reasonable’ is not a term of art. It is a judicial attempt to sketch a line beyond which conduct may be regarded as unconscionable or inequitable. Its duality, however, is a recognition that honesty alone is too pure a standard for business dealings because it omits legitimate self-interest; while reasonableness alone is capable of legitimising Machiavellian tactics.
Mistake is a concept which sits awkwardly in this space. Absent a prior accord which has simply not been carried into effect, absent also a dishonest inducement to contract, one is looking for a mistake on the claimant’s own part which the defendant was honour-bound, despite his own legitimate business interests, to point out to him. I am unable to accept that this was such a case on any tenable view of the evidence.
There are at least two kinds of mistake. One is a literal misunderstanding of some fact material to the proposed contract. The other is an error of judgment in entering into the contract. I find it difficult to think that the second kind has any relevance to the law of unilateral mistake. Nobody is bound, even in honour, to help his opposite number to negotiate to the best advantage.’
The defendant was entitled to assume that the claimant knew what it was agreeing to. Dishonesty had not been pleaded, and the judge was not entitled to find it.
Sedley LJ discussed the situation as to representations made during a negotiation: ‘There is, as it seems to me, a paradox in the notion of what an honourable and reasonable person would do in the context of an arm’s length commercial negotiation. This is a context in which honour (or honesty) and rationality (or reasonableness) are frequently not on speaking terms. I doubt that [counsel’s] submission that the two epithets qualify each other does more than compound the paradox.
Take the present case. An honourable person negotiating for [the Defendant] would probably have asked [the Claimant] if they realised that E had been left out, but I very much doubt whether a reasonable negotiator would have done so. His first duty would have been to his own principal, whose interests undoubtedly lay in leaving E out and not alerting [the Claimant] to the omission.,br />The phrase ‘honest and reasonable’ is not a term of art. It is a judicial attempt to sketch a line beyond which conduct may be regarded as unconscionable or inequitable. Its duality, however, is a recognition that honesty alone is too pure a standard for business dealings because it omits legitimate self-interest; while reasonableness is capable of legitimising Machiavellian tactics.’
