Waters and others (Appellants) v. Welsh Development Agency (Respondents)

Compensation for compulsory acquisition is the fair financial equivalent of the land taken. Open-market value includes existing potentiality and pre-existing key value, even where the acquiring authority is the only likely purchaser. It excludes enhancement attributable solely to the proposed use under a project of which the acquisition forms an integral part.

The Pointe Gourde or no-scheme rule remains part of the value-to-the-owner principle and supplements the statutory compensation code. A scheme is identified by considering its proposed works, purposes and surrounding circumstances. The tribunal must seek a fair and reasonable valuation, avoid unreal or virtually impossible exercises, use the statutory code by analogy and, when genuinely in doubt, prefer the narrower scheme. Land later selected for a compensatory measure may nevertheless be integral where the principal project proceeded throughout on the basis that such compensation would be provided.

The appellants owned 225 acres of agricultural land compulsorily acquired for the Gwent Levels Wetlands Reserve. The reserve was intended to compensate for habitats lost through construction of the Cardiff Bay barrage. The appellants accepted valuation at the higher of agricultural value and nature-reserve value, but also claimed additional ransom or key value arising from the land's asserted indispensability to the barrage project.

The Lands Tribunal, reported at [2001] 1 EGLR 185, held that rule 3 of section 5 of the Land Compensation Act 1961 did not apply, but that enhancement caused by the compensatory need had to be disregarded under the Pointe Gourde principle. The Court of Appeal dismissed the landowners' appeal in [2002] EWCA Civ 924, also reported at [2003] 4 All ER 384. The central questions were whether the reserve formed an integral part of the barrage scheme and whether open-market valuation could include the land's scheme-created key value.

1. Disposition. The House unanimously dismissed the appeal. Lord Nicholls and Lord Brown delivered the principal speeches. Lord Woolf agreed completely with both, and Lord Steyn also agreed with both. Lord Scott concurred in the result by a different route.
2. Open-market equivalence. Per Lord Nicholls, compensation must provide a fair financial equivalent for the land taken. The hypothetical transaction is between a willing seller and willing buyer. Existing potentiality and special adaptability ordinarily form part of market value, even where the acquiring authority is the only likely purchaser. The authority's urgent need and value created solely by its compulsory project do not.
3. The no-scheme rule. Per Lord Nicholls and Lord Brown, the principle in Pointe Gourde Quarrying and Transport Co Ltd v Sub-Intendent of Crown Lands [1947] AC 565 survives alongside section 6 of the Land Compensation Act 1961. It is an aspect of the established value-to-the-owner principle, rather than an independent doctrine. It excludes enhancement caused by the proposed use of the subject land and by the use of other land forming an integral part of the same scheme. The exclusion covers unrealised as well as realised scheme-created potentiality.
4. Identifying the scheme. Per Lord Nicholls, the tribunal must consider both the proposed works and their purposes, together with all relevant circumstances. Its overriding aim is a fair and reasonable financial equivalent. The rule should not be pressed so far that valuation becomes unreal or virtually impossible. Gross disparity with comparable unacquired land requires caution. The statutory code should guide the common-law rule by analogy; formal acquisition documents are important but not conclusive; and genuine doubt should be resolved in favour of the narrower scheme.
5. Key value and application. Pre-existing key value must be included, but value created entirely by the acquisition scheme must be disregarded. The compensatory reserve was integral to the barrage project. Although the appellants' particular land was selected only after barrage construction had begun, the project had proceeded throughout on the basis that compensatory habitat would be supplied. Accordingly, the authority's need for the land as a palliative for the barrage's environmental consequences was disregarded.
6. Lord Scott's alternative reasoning. Lord Scott considered that the judicially developed Pointe Gourde disregard lacked a sound statutory foundation and that the statutory disregards should control. He would have construed rule 3 more broadly and held that the claimed government-only enhancement was not value to the seller. That approach did not command the majority, which retained and confined the existing no-scheme jurisprudence.

• House of Lords: In Waters and others (Appellants) v. Welsh Development Agency (Respondents) [2004] UKHL 19, the House unanimously dismissed the appeal and affirmed the Court of Appeal's disposition.
• Court of Appeal: In [2002] EWCA Civ 924, also reported at [2003] 4 All ER 384, the court dismissed the landowners' appeal. It upheld the finding that the compensatory nature reserve was integral to the barrage project.
• Lands Tribunal: In the decision reported at [2001] 1 EGLR 185, the tribunal held that rule 3 of section 5 of the Land Compensation Act 1961 did not apply. It nevertheless required scheme-created enhancement to be disregarded under the Pointe Gourde principle.
