“6A No-scheme principle (1) The no-scheme principle is to be applied when assessing the value of land in order to work out how much compensation should be paid by the acquiring authority for the compulsory acquisition of the land (see rule 2A in section 5). (2) The no-scheme principle is the principle that— (a) any increase in the value of land caused by the scheme for which the authority acquires the land, or by the prospect of that scheme, is to be disregarded, and (b) any decrease in the value of land caused by that scheme or the prospect of that scheme is to be disregarded. (3) In applying the no-scheme principle the following rules in particular (the “no- scheme rules”) are to be observed. (4) Rule 1: it is to be assumed that the scheme was cancelled on the relevant valuation date. (5) Rule 2: it is to be assumed that no action has been taken (including acquisition of any land, and any development or works) by the acquiring authority wholly or mainly for the purposes of the scheme. (6) Rule 3: it is to be assumed that there is no prospect of the same scheme, or any other project to meet the same or substantially the same need, being carried out in the exercise of a statutory function or by the exercise of compulsory purchase powers. (7) Rule 4: it is to be assumed that no other projects would have been carried out in the exercise of a statutory function or by the exercise of compulsory purchase powers if the scheme had been cancelled on the relevant valuation date. (8) Rule 5: if there was a reduction in the value of land as a result of— (a) the prospect of the scheme (including before the scheme or the compulsory acquisition in question was authorised), or (b) the fact that the land was blighted land as a result of the scheme, that reduction is to be disregarded. (9) In this section- … “relevant valuation date” has the meaning given by section 5A [the vesting date, as above] 6 (10) See also section 14 for assumptions to be made in respect of planning permission.”
“14 Taking account of actual or prospective planning permission (1) This section is about assessing the value of land in accordance with rule (2) in section 5 for the purpose of assessing compensation in respect of a compulsory acquisition of an interest in land. (2) In consequence of that rule, account may be taken— (a) of planning permission, whether for development on the relevant land or other land, if it is in force at the relevant valuation date, and (b) of the prospect, on the assumptions set out in subsection (5) but otherwise in the circumstances known to the market at the relevant valuation date, of planning permission being granted on or after that date for development, on the relevant land or other land, other than— (i) development for which planning permission is in force at the relevant valuation date, and (ii) appropriate alternative development. (3) In addition, it may be assumed— (a) that planning permission is in force at the relevant valuation date for any development that is appropriate alternative development to which subsection (4)(b)(i) applies, and (b) that, in the case of any development that is appropriate alternative development to which subsection (4)(b)(ii) applies and subsection (4)(b)(i) does not apply, it is certain at the relevant valuation date that planning permission for that development will be granted at the later time at which at that date it could reasonably have been expected to be granted. (4) For the purposes of this section, development is “appropriate alternative development” if— (a) it is development, on the relevant land alone or on the relevant land together with other land, other than development for which planning permission is in force at the relevant valuation date, and (b) on the assumptions set out in subsection (5) but otherwise in the circumstances known to the market at the relevant valuation date, planning permission for the development could at that date reasonably have been expected to be granted on an application decided— 7 (i) on that date, or (ii) at a time after that date. (5) The assumptions referred to in subsections (2)(b) and (4)(b) are— (a) that the scheme of development underlying the acquisition had been cancelled on the launch date, (b) that no action has been taken (including acquisition of any land, and any development or works) by the acquiring authority wholly or mainly for the purposes of the scheme, (c) that there is no prospect of the same scheme, or any other project to meet the same or substantially the same need, being carried out in the exercise of a statutory function or by the exercise of compulsory purchase powers, and (d) if the scheme was for use of the relevant land for or in connection with the construction of a highway (“the scheme highway”), that no highway will be constructed to meet the same or substantially the same need as the scheme highway would have been constructed to meet. …”
“In assessing the compensation to be paid by the acquiring authority under this Act regard shall be had not only to the value of the land to be purchased by the acquiring authority, but also to the damage, if any, to be sustained by the owner of the land by reason of the severing of the land purchased from the other land of the owner, or otherwise injuriously affecting that other land by the exercise of the powers conferred by this or the special Act.”
“…by virtue of the significantly further forward projection of the proposed building, its height at its tallest and thus resulting scale so close to the back edge of the pavement it would dominate this part of the street scene. The increased prominence would not only jar visually with the much smaller scale of the opposite more traditional terraced housing but also make the street overall appear unbalanced. The resulting building would have a looming and over- bearing impression on a human scale and as a result reduce the quality of the public realm at this point.”
“…the effect of rule (2) is clear. The Reference Land must be valued as if it alone was being sold on the open market by a willing seller. This is a hypothetical basis because the seller – the claimant – may be anything but willing, particularly if the Reference Land forms an important part of other land retained by it. Insofar as the claimant suffers a loss because of a diminution in the value of Retained Land then this will form a claim for compensation for severance and/or injurious affection. It does not justify adopting an artificial approach to valuing the Reference Land as if is still formed part of a larger whole.”
“We accept that, in order to value land compulsorily acquired under rule (2), it is usual to analyse comparable transactions to identify a value per square foot for the land which is then applied to the area of land acquired. However, in our judgment it is not necessarily appropriate to carry out the same exercise on a before and after basis in order to demonstrate a diminution in the value of Retained Land by reason of part of it having been compulsorily acquired. Whether that is the correct approach will depend on the evidence. But the issue at the end of the day under s.7 of the 1965 Act is whether the claimant can demonstrate that the Retained Land is in fact worth less as a result of the loss of the land acquired.”
“The guiding principle in the assessment of compensation is the principle of equivalence. The landowner whose land is taken in the public interest should receive compensation which fully and fairly reflects the loss which the owner has actually suffered, no more and no less.”
