“124. There is a considerable amount of case law on the meaning of "exceptional circumstances" in this context. I was particularly referred to Carpets of Worth Limited v Wyre Forest District Council(1991) 62 P & CR 334 ("Carpets of Worth"), Laing Homes Limited v Avon County Council(1993) 67 P & CR 34 ("Laing Homes"), COPAS v Royal Borough of Windsor and Maidenhead[2001] EWCA Civ 180 ;[2002] P & CR 16 ("COPAS"), and R (Hague) v Warwick District Council[2008] EWHC 3252 (Admin) ("Hague"). ” 125. From these authorities, a number of propositions are clear and uncontroversial. i) Planning guidance is a material consideration for planning plan-making and decision-taking. However, it does not have statutory force: the only statutory obligation is to have regard to relevant policies. ii) The test for redefining a Green Belt boundary has not been changed by the NPPF (nor did Mr Dove suggest otherwise). a) In Hunston, Sir David Keene said (at [6]) that the NPPF "seems to envisage some review in detail of Green Belt boundaries through the new Local Plan process, but states that 'the general extent of Green Belts across the country is already established'". That appears to be a reference to paragraphs 83 and 84 of the NPPF. Paragraph 83 is quoted above (paragraph 109). Paragraph 84 provides: "When drawing up or reviewing Green Belt boundaries local planning authorities should take account of the need to promote sustainable patterns of development…". However, it is not arguable that the mere process of preparing a new local plan could itself be regarded as an exceptional circumstance justifying an alteration to a Green Belt boundary. National guidance has always dealt with revisions of the Green Belt in the context of reviews of local plans (e.g. paragraph 2.7 of PPG2: paragraph 83 above), and has always required "exceptional circumstances" to justify a revision. The NPPF makes no change to this. b) For redefinition of a Green Belt, paragraph 2.7 of PPG2 required exceptional circumstances which "necessitated" a revision of the existing boundary. However, this is a single composite test; because, for these purposes, circumstances are not exceptional unless they do necessitate a revision of the boundary (COPAS at [23] per Simon Brown LJ). Therefore, although the words requiring necessity for a boundary revision have been omitted from paragraph 83 of the NPPF, the test remains the same. Mr Dove expressly accepted that interpretation. He was right to do so. iii) Exceptional circumstances are required for any revision of the boundary, whether the proposal is to extend or diminish the Green Belt. That is the ratio of Carpets of Worth. iv) Whilst each case is fact-sensitive and the question of whether circumstances are exceptional for these purposes requires an exercise of planning judgment, what is capable of amounting to exceptional circumstances is a matter of law, and a plan-maker may err in law if he fails to adopt a lawful approach to exceptional circumstances. Once a Green Belt has been established and approved, it requires more than general planning concepts to justify an alteration.” i) Planning guidance is a material consideration for planning plan-making and decision-taking.
