There were mini-celebrations in the private sector when the Court of Appeal gave its judgement in March on the conjoined appeals of Suffolk Coastal DC v Hopkins Homes & SSCLG and Richborough Estates v Cheshire East BC & SSCLG  EWCA Civ 168. The case primarily concerned the meaning of relevant policies for the supply of housing in paragraph 49 of the NPPF, as well as the effect of such policies being deemed out-of-date by paragraph 49 where there was not a five year housing land supply.
33. Our interpretation of the policy does not confine the concept of “policies for the supply of housing” merely to policies in the development plan that provide positively for the delivery of new housing in terms of numbers and distribution or the allocation of sites. It recognizes that the concept extends to plan policies whose effect is to influence the supply of housing land by restricting the locations where new housing may be developed – including, for example, policies for the Green Belt, policies for the general protection of the countryside, policies for conserving the landscape of Areas of Outstanding Natural Beauty and National Parks, policies for the conservation of wildlife or cultural heritage, and various policies whose purpose is to protect the local environment in one way or another by preventing or limiting development. It reflects the reality that policies may serve to form the supply of housing land either by creating it or by constraining it – that policies of both kinds make the supply what it is. […]
35. Restrictive policies, whether broadly framed or designed for some more specific purpose, may – we stress “may” – have the effect of constraining the supply of housing land. If they do have that effect, they may – again, we emphasize “may” – act against the Government’s policy of boosting significantly the supply of housing land. If a local planning authority is unable to demonstrate the requisite five-year supply of housing land, both the policies of its local plan that identify sites for housing development and policies restrictive of such development are liable to be regarded as not “up-to-date” under paragraph 49 of the NPPF – and “out-of-date” under paragraph 14. Otherwise, government policy for the delivery of housing might be undermined by decisions in which development plan policies that impede a five-year supply of housing land are treated as “up-to-date”.
46. We must emphasize here that the policies in paragraphs 14 and 49 of the NPPF do not make “out-of-date” policies for the supply of housing irrelevant in the determination of a planning application or appeal. Nor do they prescribe how much weight should be given to such policies in the decision. Weight is, as ever, a matter for the decision-maker … Neither of those paragraphs of the NPPF says that a development plan policy for the supply of housing that is “out-of-date” should be given no weight, or minimal weight, or, indeed, any specific amount of weight. They do not say that such a policy should simply be ignored or disapplied. That idea appears to have found favour in some of the first instance judgments where this question has arisen. It is incorrect.
47. One may, of course, infer from paragraph 49 of the NPPF that in the Government’s view the weight to be given to out-of-date policies for the supply of housing will normally be less than the weight due to policies that provide fully for the requisite supply. The weight to be given to such policies is not dictated by government policy in the NPPF. Nor is it, nor could it be, fixed by the court. It will vary according to the circumstances, including, for example, the extent to which relevant policies fall short of providing for the five-year supply of housing land, the action being taken by the local planning authority to address it, or the particular purpose of a restrictive policy – such as the protection of a “green wedge” or of a gap between settlements. There will be many cases, no doubt, in which restrictive policies, whether general or specific in nature, are given sufficient weight to justify the refusal of planning permission despite their not being up-to-date under the policy in paragraph 49 in the absence of a five-year supply of housing land. Such an outcome is clearly contemplated by government policy in the NPPF. It will always be for the decision-maker to judge, in the particular circumstances of the case in hand, how much weight should be given to conflict with policies for the supply of housing that are out-of-date. This is not a matter of law; it is a matter of planning judgment …
48. The policies in paragraphs 14, 47 and 49 of the NPPF are not, as we understand them, intended to punish a local planning authority when it fails to demonstrate the requisite five-year supply of housing land. They are, however, clearly meant to be an incentive…”
Until such time as the appeal is heard in the Supreme Court, the above paragraphs assist in the general understanding of the meaning of relevant policies for the supply of housing in paragraph 49 of the NPPF, as well as the effect of such policies being deemed out-of-date by paragraph 49 where there was not a five year housing land supply.
