Westfield Park Limited v Harworth Estates Investments Limited

Contractual interpretation is an objective and unitary exercise. The court must begin with the natural meaning of the language, but read it in its immediate and wider contractual context, against the relevant background and commercial consequences. Prior negotiations and subjective intentions are irrelevant.

Where an agreement makes payment conditional on land being released from a defined restriction, permission for a particular use within the restricted area does not satisfy that condition. A reference to the restricted area may operate dynamically throughout the agreement, so that a later reduction applies to all connected provisions.

Rectification requires proof that both parties actually shared the alleged intention and that they communicated an outward expression of accord. It cannot be granted by assembling findings made for other purposes.

Harworth sold a holiday-park development to Westfield for £2.6 million. The agreement provided for deferred consideration, up to £400,000, if the Coal Authority reduced a defined 27-metre mine-shaft Zone of Influence before a long-stop date.

The Coal Authority later permitted static caravans outside the protective caps but confirmed that the 27-metre zone itself had not been reduced. Harworth claimed the deferred consideration. HHJ Klein, sitting as a High Court judge, construed the agreement as making payment due when the Coal Authority permitted static caravans within the area: [2024] EWHC 2550 (Ch).

Westfield appealed. Harworth also relied on a respondent’s notice, contending that payment was due on a proper construction or, alternatively, that the agreement should be rectified to reflect a common intention concerning the siting of static caravans.

1. Appeal allowed; respondent’s notice dismissed. The Coal Authority’s letter did not trigger Westfield’s obligation to pay the Released Land Value. It permitted a particular use in part of the area, but it did not reduce or release the defined Zone of Influence.
2. The judge had not applied the established approach to contractual construction. Interpretation required an objective, unitary assessment of the natural meaning of the words, their immediate and wider context, the agreement’s purpose, the background known or assumed by the parties, and commercial common sense. Prior negotiations and subjective intentions were irrelevant. The judge’s conclusion that the Coal Authority lacked power to reduce the zone had no evidential foundation.
3. Read as a professionally drafted agreement, Schedule 4 consistently used the language of a reduction or release of the Zone of Influence. It did not refer to permission for a particular use, partial exoneration, or a change of use. Clause 5 did not fix the defined area permanently as at the agreement date. If the Zone of Influence were reduced or released, the reference in clause 5 would reduce correspondingly. Thus, no commercial absurdity justified departing from the ordinary meaning.
4. The alternative rectification case failed. Rectification is available where a document fails to record the parties’ actual common intention, provided that there was an outward expression of accord. The first-instance judge made no findings of a shared intention on the alternative claim. Findings about one party’s proposal, the parties’ earlier focus on caravans, and the judge’s construction could not be combined to create such findings. The Court declined to remit the issue, which had not been pursued and would require the judge to reconsider evidence after substantial time.

• Court of Appeal (Civil Division): Allowed Westfield’s appeal and dismissed Harworth’s Respondent’s Notice: [2025] EWCA Civ 1374.
• High Court, Chancery Division: HHJ Klein, sitting as a High Court judge, held that the deferred consideration was payable on the construction of Schedule 4: [2024] EWHC 2550 (Ch).
