Factual and Procedural Background
The Plaintiff, an assurance company, had invested in a portfolio of ground rents principally in a major city area. Initially considered a stable investment, ground rents became problematic by the mid-1970s due to rampant inflation, increased collection costs, and organized resistance from tenants. Legislation also enabled tenants to buy out ground rents at a capped price, prompting the Plaintiff to seek disposal of its portfolio.
In April 1981, an estate agent introduced a prospective purchaser, a London-based property developer with no prior experience in the local market. The parties agreed on a purchase price based on a multiplier of the rental income, and solicitors were instructed to handle the transaction.
The portfolio included properties with potential for profitable development, notably a large tract of vacant land at Palmerstown subject to Compulsory Purchase Orders (CPOs) by local authorities. The Plaintiff intended to exclude these Palmerstown lands and certain residential properties from the sale. This intention was communicated to the estate agent acting on behalf of the purchaser.
Despite these instructions, due to an oversight in the Plaintiff's legal department, the Palmerstown lands and some adjoining properties were mistakenly included in the written contract executed and exchanged on 23 December 1981.
The mistake was discovered in March 1982, when the Plaintiff's solicitor informed the purchaser's solicitor that the Palmerstown lands would not be transferred. The purchaser formed a local company to take title to the portfolio, but disputes arose regarding the inclusion of the Palmerstown lands and two residential properties erroneously included.
A meeting in November 1982 revealed the purchaser's willingness to accept the mistake but also their desire to benefit from it. The Plaintiff then instituted proceedings seeking:
- Rectification of the contract to reflect the parties' true intentions excluding the Palmerstown lands and certain properties;
- Specific performance of the rectified contract.
The Defendant counterclaimed for declarations confirming ownership of the Palmerstown lands and specific performance of the contract as executed.
Legal Issues Presented
- Whether the contract dated 23 December 1981 should be rectified to exclude the Palmerstown lands and certain properties on the ground of mutual mistake.
- Whether the Plaintiff discharged the burden of proof required to establish a common continuing intention not reflected in the contract.
- Whether the knowledge of the estate agent acting for the purchaser can be imputed to the purchaser for the purpose of rectification.
- The applicability of equitable principles and precedents concerning rectification for unilateral mistake or absence of fraud or sharp practice.
- Whether the Defendant is entitled to specific performance of the contract as executed.
Arguments of the Parties
Plaintiff's Arguments
- The contract was executed under a mutual mistake of fact regarding the inclusion of the Palmerstown lands.
- There was a common continuing intention between the parties to exclude the Palmerstown lands, which was communicated through the purchaser’s agent.
- Rectification is appropriate even without an enforceable antecedent agreement, relying on established case law.
- The purchaser’s agent had actual knowledge of the exclusion, imputing that knowledge to the purchaser.
Defendant's Arguments
- There was no mistake in the contract; the parties intended to include the properties set out in the schedules, regardless of any informal understandings.
- The purported exclusion was too vague and uncertain to constitute a concluded antecedent agreement.
- The case involves unilateral mistake, which does not justify rectification absent fraud or sharp practice.
- The purchaser was unaware of the exclusion and did not assent to it; the agent’s knowledge cannot bind the purchaser to terms not communicated.
- Equity requires clear and convincing proof of mutual mistake, which the Plaintiff failed to provide.

Court's Reasoning and Analysis
The Court carefully examined the evidence regarding the parties’ intentions and the role of the estate agent. It found that the Plaintiff intended to exclude the Palmerstown lands and certain properties from the sale and had communicated this to the agent acting for the purchaser. However, the written contract mistakenly included these lands due to an oversight in the Plaintiff's legal department.
The Court held that for rectification, there must be a common continuing intention outwardly expressed and communicated, and a concluded antecedent agreement or prior accord concerning the disputed term. The Plaintiff bore a heavy burden of proof to establish this.
While the agent had knowledge of the intended exclusion, the purchaser was unaware until after contract execution. The Court emphasized that knowledge of an agent does not automatically bind the principal to terms omitted by mistake, especially where the principal has no actual knowledge or assent.
The Court distinguished this case from those where rectification was granted due to fraud, dishonesty, or sharp practice. Here, no such inequitable conduct was found. The purchaser was not aware of the mistake, and there was no evidence of any attempt to exploit it.
The Court also noted the uncertainty and vagueness in the Plaintiff’s instructions regarding the exact scope of the Palmerstown lands to be excluded, which undermined the claim of a concluded antecedent agreement.
Accordingly, the Court found that the Plaintiff failed to discharge the heavy burden of proving a mutual mistake entitling them to rectification. The mistake was unilateral, and the absence of fraud or sharp practice precluded rectification.
Regarding ownership of the Palmerstown lands, the Court held that service of Notices to Treat did not transfer legal or equitable title, which remained with the Plaintiff at the contract date. The Defendant, therefore, became entitled to the lands or compensation under the contract.
Holding and Implications
The Plaintiff's claim for rectification was dismissed.
The Defendant was entitled to declarations confirming ownership of the Palmerstown lands and an order for specific performance of the contract as executed.
The decision clarifies the strict requirements for rectification based on mistake, emphasizing the necessity of a common continuing intention clearly communicated and the heavy burden on a party seeking such relief. It underscores that knowledge of an agent alone does not bind a principal to omitted contract terms absent actual assent or inequitable conduct.
No new precedent was established; the ruling applies existing principles of contract rectification and agency law to the facts of the case.
