"The task [for the Panel] is to consider whether the core allegations are true. It is a commonplace for there to be inconsistency and confusion about details of varying importance."
"The reasons for a decision must be intelligible and they must be adequate. They must enable the reader to understand why the matter was decided as it was and what conclusions were reached on the "principal important controversial issues", disclosing how any issue of law or fact was resolved. Reasons can be briefly stated, the degree of particularity required depending entirely on the nature of the issues falling for decision. The reasoning must not give rise to a substantial doubt as to whether the decision-maker erred in law, for example by misunderstanding some relevant policy or some other important matter or by failing to reach a rational decision on relevant grounds. But such adverse inference will not readily be drawn. The reasons need refer only to the main issues in the dispute, not to every material consideration. They should enable disappointed developers to assess their prospects of obtaining some alternative development permission, or, as the case may be, their unsuccessful opponents to understand how the policy or approach underlying the grant of permission may impact upon future such applications. Decision letters must be read in a straightforward manner recognising that they are addressed to parties well aware of the issues involved and the arguments advanced. A reasons challenge will only succeed if the party aggrieved can satisfy the court that he has genuinely been substantially prejudiced by the failure to provide an adequately reasoned decision."
"I hope I am not over-simplifying unduly by suggesting that the central issue in this case is whether the decision of the Secretary of State leaves room for genuine as opposed to forensic doubt as to what he has decided and why. This is an issue to be resolved as the parties agree on a straightforward down-to-earth reading of his decision letter without excessive legalism or exegetical sophistication." "at least the reasoning of the Secretary of State did not explain why those disadvantages [of Option A] had to be accepted." (paragraph 73) "
“The correct approach Before dealing with each of these challenges, I should first make some preliminary observations on the correct approach to decision letters in planning appeals, with which alone we are concerned in this case. This can be done very briefly, since the question was fully covered in the recent speech of Lord Bridge of Harwich in Save Britain's Heritage v. No. 1 Poultry Ltd. ([1991] 1 WLR 153 ) Under section 70(2) of the Act of 1990, read with section 77(4) , it was the duty of the Secretary of State to have regard “to the provisions of the development plan … and to any other material considerations”
“It seems to me that the decision must be such that it enables the appellant to understand on what grounds the appeal has been decided and be in sufficient detail to enable him to know what conclusions the inspector has reached on the principal important controversial issues”
“In relation to two of these issues. Schiemann J. in the passages I have quoted said that it is ‘fanciful to postulate’ that the Secretary of State did not take these matters into account, nor give them appropriate weight. With all respect to a judge with great experience in this field, I do not think this is a proper approach. A decision letter must, in order to give proper and adequate reasons, refer to each material consideration, and explain why because or despite it the eventual decision is reached. At the least, if there is no express reference to some matter, it must be possible for the reader to infer that the words used implied such a reference.”
