“This distinction between whether something is a material consideration and the weight which it should be given is only one aspect of a fundamental principle of British planning law, namely that the courts are concerned only with the legality of the decision-making process and not with the merits of the decision. If there is one principle of planning law more firmly settled than any other, it is that matters of planning judgment are within the exclusive province of the local planning authority or the Secretary of State.”
“…If the planning authority ignores a material consideration because it has forgotten about it, or because it wrongly thinks that the law or departmental policy (as in Safeway Properties Ltd v Secretary of State for the Environment [1991] JPL 966) precludes it from taking it into account, then it has failed to have regard to a material consideration. But if the decision to give that consideration no weight is based on rational planning grounds, then the planning authority is entitled to ignore it.” 30. Thus, in appropriate circumstances, a local planning authority in the reasonable exercise of its discretion may give no significant weight or even no weight at all to a consideration material to its decision, provided that it has had regard to it. 31. What is capable of being a material consideration for the purposes of a planning decision? This question has on several occasions been considered by the courts. The concept of materiality is wide. In principle, it encompasses any consideration bearing on the use or development of land. Whether a particular consideration is material in a particular case will depend on the circumstances (see the judgment of Cooke J. in Stringer v Minister of Housing and Local Government [1970] 1 W.L.R. 1281; (1971) 22 P. & C.R. 255 (at p.1294G)). In the context of development plan-making and development control decision-taking, the test of materiality formulated by Lord Scarman in his speech in Westminster City Council v Great Portland Estates Plc [1995] A.C. 661; (1985) 50 P. & C.R. 20 (at p.669H to p.670C-E) is whether the consideration in question “serves a planning purpose”, which is one that “relates to the character and use of land”.“ “This distinction between whether something is a material consideration and the weight which it should be given is only one aspect of a fundamental principle of British planning law, namely that the courts are concerned only with the legality of the decision-making process and not with the merits of the decision. If there is one principle of planning law more firmly settled than any other, it is that matters of planning judgment are within the exclusive province of the local planning authority or the Secretary of State.”
