Centrovinicial Estates Plc v Merchant Investors Assurance Company Ltd [1983]

Centrovinicial Estates Plc v Merchant Investors Assurance Company Ltd [1983] Com LR 158 revolves around the issue of a unilateral mistake in a contract and the conditions under which such a mistake renders the contract void. The central principle established in this case is that for a contract to be void due to a unilateral mistake in terms, the party making the mistake must have known or should have known about the mistake made by the other party.

In the factual background of the case, the landlord inadvertently offered a rent of £65,000 per year instead of the intended £126,000 per year to the tenant. Despite the mistake, the tenant accepted the offer, prompting the landlord to seek a declaration that the contract was void due to the unilateral mistake.

The trial judge had initially granted summary judgment in favour of the landlord, but the Court of Appeal took a different stance. Leave was given to the tenant to defend the action, and Slade LJ, in delivering the judgment, highlighted that the landlord needed to establish that the tenant either knew or should have known about the mistake at the time of accepting the offer for the contract to be void.

The significance of this case lies in its emphasis on the objective nature of contracts. Slade LJ clarified that the binding nature of contracts is not contingent on estoppel, and there is no requirement for the landlord to demonstrate detrimental reliance to enforce the contract. The decision underscores the importance of objectively assessing whether a reasonable person in the position of the party receiving the offer would understand the intention of the offering party, taking into account both subjective and objective elements.

In terms of legal procedures, the grant of leave implies that the case will proceed to a full trial, allowing the tenant the opportunity to defend against the landlord's claim. The case draws parallels with the objective approach in contract law, as exemplified in Smith v Hughes [1871], reinforcing the notion that a reasonable person's understanding of contractual terms is crucial in determining the validity and enforceability of contracts.

Overall, Centrovinicial Estates Plc v Merchant Investors Assurance Company Ltd contributes to the jurisprudence on contract law and the nuanced considerations surrounding unilateral mistakes in contractual agreements.
