“1 … no account shall be taken of any increase or diminution in the value of the relevant interest which, in the circumstances described in any of the paragraphs in the first column of Part I of the First Schedule to this Act, is attributable to the carrying out or the prospect of so much of the development mentioned in relation thereto in the second column of that Part as would not have been likely to be carried out if - (a) (where the acquisition is for purposes involving development of any of the land authorised to be acquired) the acquiring authority had not acquired and did not propose to acquire any of the land; …”
“Where the acquisition is for purposes involving development of any of the land authorised to be acquired.”
“Development of any of the land authorised to be acquired, other than the relevant land, being development for any of the purposes for which any part of the first-mentioned land (including any part of the relevant land) is to be acquired.”
“53. Both parties focused in their evidence and submissions upon the prospects of a purchaser obtaining a residential permission on the reference land in those two different situations. The ‘cancellation universe’ assumed that the compulsory purchase orders on the reference land had been cancelled but that access could be obtained through the KBP. In that situation it was broadly agreed that the reference land might indeed have some potential hope value for residential development. 54. The claimant said it would be substantial. The acquiring authority maintained that any such hope value would be much reduced, probably to nil, because the planning authority would not be prepared to grant a permission that did not conform with the master plan requirements for phasing, which would delay residential development, or make a very substantial financial contribution to the infrastructure of the KBP. Finally, the acquiring authority submitted, any such value that remained should be disregarded as a matter of law. 55. The second situation was postulated in order to consider what value the reference land might have if the law required that the whole of the KBP proposals had to be left out of consideration. That situation was chiefly one where permission was being sought for a development with access from Buckley Hill Lane, although we do not think the claimant completely abandoned the possibility that in the ‘no KBP’ universe a purchaser would still contemplate the development of a business park by another scheme.”
“89. We think that simply on the cancellation assumption there would have been a reasonable prospect of some residential development on the reference land with access from a northern loop. However, it would seem that such an increase in the value of the relevant interest would have to be disregarded. It would be unequivocally attributable to the development of part of the land authorised to be acquired other than the relevant land, and it would not have been likely to be carried out in the absence of the acquiring authority’s proposals to acquire the land for such a road.”
“97. It was evident from our site visit that there has been development off Buckley Hill Lane in the comparatively recent past on its eastern side. The long history of the identification of the land of which the reference land forms part for substantial development would weaken a PPG 3 greenfield objection to a residential development on the west side of the lane, incorporating the Nib. It was agreed between the highway witnesses that a substantial number of houses could take an access on to Buckley Hill Lane although the witnesses differed as to whether the maximum would be 60 or 74. For the reasons we have just given we think we should give less weight, in considering the prospects of this hypothetical permission, to an objection based upon policy EC/6 or emerging policy EC/7 and no weight to a highway objection based upon traffic flows from the KBP development. On the other hand the motorway junction itself was a fact on the ground at the valuation date. It was not part of the compulsory purchase order and it does not seem to us that it would be right to extend the definition of the scheme to include it. 98. Taking all those matters into consideration and doing the best we can to make sense of a number of assumptions of varying solidity, in our judgement the hypothetical purchaser would have considered that the reference land would have had some extra hope value of a permission for residential development. However we would not put a percentage better than 50/50 on the chances of success.”
“32. HCA’s primary submission is that the UT has done the very thing which … they had said was to be avoided: namely eliding the identification of the planning status of the reference land with its valuation. They submit that once the planning status is determined by the application of sections 14-16 of the 1961 Act the valuation exercise has to proceed on that basis and that the application of the section 6 disregards does not involve any further alteration in the assumed planning permissions or policies which have previously been determined to apply …”
“40. In my view, the [Upper Tribunal] was right to hold that the planning status of the reference land did have to be modified for the purposes of valuation in accordance with the ‘no KBP universe’ methodology. But it was wrong to do so by simply downgrading the strict application of the existing and emerging development plan but otherwise leaving the allocation of the land for development in place. What it should have done was to consider the planning potential of the reference land without regard to the development scheme and its underlying policies and therefore its effect on value. In that no scheme world it should have examined what wider no scheme specific policies (including but not necessarily limited to PPG3) would have applied to a planning application at the valuation date had there been no KBP and so struck a fair balance between the public interest and those of the claimant in relation to the valuation of the reference land. The assumption relied on in both parties’ submissions that policy EC/6 and developing policy EC/7 continued to apply was based on a wrong application of section 6(1) and the valuation calculated on that basis must be set aside.”
“52. In the present case … the [Upper Tribunal] erred by still giving weight … to the planning policies in relation to the KBP site, including in particular the part of the historic, current and emerging policies to promote the development of a business park which contemplated that there should be residential development on the site as part of that development (what the [Upper Tribunal] called ‘the extensive policy support for residential development on part of the reference land’: para 96). In this respect, the [Upper Tribunal] failed to apply the section 6(1) disregard correctly and appears to have overvalued the reference land for the purposes of compensation.”
“24. We mention in passing Mr Barnes’ argument before the tribunal (see para 61), not pressed in this court, that the noscheme rule had nothing to do with planning assumptions, being ‘a principle of valuation and not planning status’. This argument was based on some comments of Lord Denning MR in Myers v Milton Keynes Development Corpn[1974] 1 WLR 696 , and of Carnwath LJ in Roberts v South Gloucestershire Council [2003] RVR 43. He was right in our view not to pursue the point. The observations in Roberts were certainly not intended to support such an argument. It is also inconsistent with the reasoning of Lord Denning himself in the second Jelson case, and with one of the leading cases in the Privy Council, Melwood Units Pty Ltd v Main Roads Comr[1979] AC 426 (assumed permission for a shopping centre).”
