Secretary of State for Transport v Christos & Anor

An offer for the sale of land expressed to be subject to contract remains non-binding unless that condition is waived or formal contracts are exchanged. This applies to an offer to settle compensation following compulsory acquisition. The offer does not, without more, amount to a representation of the property’s true value and cannot found an equitable estoppel concerning the price.

Where parties agree a single valuation date for compulsorily acquired property, compensation must reflect the property’s physical condition on that date. Deterioration after that date does not reduce compensation, although it may found a separate claim outside the tribunal’s valuation jurisdiction.

The Secretary of State compulsorily acquired the respondents’ home and surrounding land for the Channel Tunnel Rail Link. The parties agreed that the whole property should be valued as a single entity on 17 May 1999, although possession was taken in stages.

The Lands Tribunal awarded compensation of £618,945. It found no binding contract at £500,000, but held that the acquiring authority was estopped from advancing valuation evidence below that figure, subject to a deduction for defective title. It also refused to deduct £8,500 for water damage occurring after the agreed valuation date.

The Secretary of State appealed on estoppel and post-valuation damage. The owners cross-appealed on the contract issue. The central questions were the effect of the continuing subject to contract qualification and the consequences of the agreed valuation date.

1. Disposition. The court unanimously allowed the acquiring authority’s appeal on equitable estoppel, dismissed its appeal on post-valuation damage, and dismissed the respondents’ cross-appeal on contract. The matter was remitted to the Lands Tribunal to redetermine compensation on the basis that the authority could adduce valuation evidence.

2. Contract. Per Mummery LJ, the £500,000 offer and its purported acceptance remained subject to contract. In a land transaction, that expression means that no binding agreement arises until formal written contracts are exchanged, unless the condition is waived. The later letter stating that the authority would not renegotiate the figure did not waive the condition. The special features of compulsory acquisition did not alter that result: the price agreement was not unconditional and the notice to treat had not then covered the whole property.

3. Estoppel. The Tribunal had overlooked the continuing significance of the qualification. An offer to settle at £500,000, made and maintained subject to contract, was a willingness to negotiate at that figure. It was not a representation of the property’s actual value and could not estop the authority from relying on valuation evidence. The circumstances differed from those in Salvation Army Trustee Co Ltd v West Yorkshire Metropolitan CC, because there the detrimental reliance was on unqualified representations concerning acquisition and compensation.

4. Valuation date. The agreement on 17 May 1999 as the single valuation date conclusively required valuation in the property’s condition on that date. Water damage occurring later could not reduce statutory compensation. Any liability for that damage was a separate matter beyond the Tribunal’s valuation function.

• Court of Appeal (Civil Division): The acquiring authority succeeded on the equitable-estoppel issue, failed on the post-valuation damage issue, and the owners’ cross-appeal on contract was dismissed. The compensation determination was remitted.
• Lands Tribunal: By an order dated 8 November 2002, the Tribunal awarded £618,945 compensation. It found no binding contract, upheld an equitable estoppel as to a £500,000 value subject to title, and declined to deduct post-valuation water damage.
