“59………….The principal point which emerges from the authorities cited is that the question of whether a local planning authority has sufficient information in order to be able to reach a proper judgment on its screening opinion is a matter for the relevant decision maker whose view is challengeable only on normal judicial review grounds. It is very much a matter of planning judgment, which depends on the facts of the given case. It may not therefore be very persuasive to take the circumstances of one case ……and to try to use it as a measure by which other cases had been judged. 60. What was said in [R(Jones) v Mansfield District Council[2003] EWHC Civ 1408 ] is particularly apposite: the planning authority must have sufficient information to be able to reach the relevant conclusion; it is not necessary that all uncertainties be resolved or that a detailed and comprehensive assessment be made of impacts at the screening opinion stage. That stage cannot turn into something equivalent to the environmental statement itself. An understanding of where the uncertainties lie and the likely range of those uncertainties may be necessary in order to be satisfied that the development is not likely to have significant environmental effects. The nature and range of the uncertainties may make it impossible to reach the conclusion that development is not EIA development. Equally, it is possible to have sufficient information for reaching a decision on the screening opinion, even though there are uncertainties and further surveys are required for the final decision on the development permission………….. It may well be possible in any given case to conclude that it is unlikely that uncertainties will be resolved in such a way as to yield a significant environmental effect. The availability of standard conditions or other straight forward and obvious remedial measures may well bite on that conclusion as well. 61. …………. 62. Indicative material can assist in judging whether the range of uncertainties is so great that a planning officer has insufficient knowledge to judge whether there are likely to be significant environmental effects or whether there are some site layouts or designs for which it can be said that they would be likely and then likely to have significant effects. The planning officer will also be able to make a judgment about the degree to which standard conditions can at that stage be envisaged as sufficient to make unlikely those developments layouts or components which would be likely to have significant environmental effects.”
