"The issues within the PCL were fully examined in a fully contested dispute between directly interested parties. The same cannot be said in respect of other areas. The judgment that the same deferment rate should apply outside the PCL area was made, and could only be made, on the evidence then available. That must leave the way open to the possibility of further evidence being called by other parties in other cases directly concerned with different areas. The deferment rate adopted by the tribunal will no doubt be the starting point; and their conclusions on the methodology, including the limitations of market evidence, are likely to remain valid. However, it is possible to envisage other evidence being called, for example, on issues relevant to the risk premium for residential property in different areas. That will be a matter for those advising future parties, and for the tribunals, to consider as such issues arise."
"35. Thus evidence of valuers as to whether a higher risk premium should be taken because of the features of the property under consideration, including its location, is of undoubted relevance, and if a tribunal is satisfied on the evidence before it that such features justify the application of a higher deferment rate then, of course, it ought to apply such higher rate. In determining whether a higher rate is appropriate it will need to bear in mind the considerations that led the Tribunal in Sportelli to adopt the approach that it did, and the primary question will always be whether there are particular features that are not fully reflected in the vacant possession value and thus should be reflected in a higher risk premium. Moreover - and this is a matter that may not, or may not sufficiently, emerge from the Tribunal's post-Sportelli decisions -what matters is the view that the market, properly informed on relevant factual matters, would take on such features (the prospective movement of house prices in the area, for instance, or the potential obsolescence of the property) in considering an investment in the reversion. On this the expert opinion of the valuer is likely to be important."
"As with location, while we do not rule out the possible need to adjust the deferment rate to take account of such matters as obsolescence and condition, we think that it would only exceptionally be the case that such factors were not fully reflected in the vacant possession value and the risk premium. Evidence would be needed to establish that they were not fully reflected in this way."
"In order to provide a reliable indication of the long term movement in residential values so as to justify a departure form the Sportelli starting point, we consider that a period in the region of 50 years should be looked at, and that a series of statistics with different starting dates should be considered in order to ensure that an unrepresentative period is not relied upon."
"We think, however, that an adjustment needs to be made to reflect the greater management problems [associated with flats], although we do not consider it appropriate to differentiate between flats that are the subject of headleases and those which are not. Nor do we think that the management concerns are necessarily so much less for a single flat than for a block to warrant a different adjustment. Even where flats are efficiently managed, service charge and repairs problems inevitably occur, and the management exercise in itself is, we feel, sufficiently more complex to warrant a generalised 0.25% additions for flats. We do not consider that any fine-tuning below this percentage is justified."
