“…. whatever the legal character of the document in question, the starting point – and usually the end point – is to find “the natural and ordinary meaning” of the words there used, viewed in their particular context (statutory or otherwise) and in the light of common sense.”
“As will have become apparent, however, and in agreement also with Lord Hodge JSC, I do not think it is right to regard the process of interpreting a planning permission as differing materially from that appropriate to other legal documents. As has been seen, that was not how it was regarded by Lord Denning in the Fawcett case[1961] AC 636 . Any such document of course must be interpreted in its particular legal and factual context. One aspect of that context is that a planning permission is a public document which may be relied on by parties unrelated to those originally involved. (Similar considerations may apply to other forms of legal document, for example leases which may need to be interpreted many years, or decades, after the original parties have disappeared or ceased to have any interest.) It must also be borne in mind that planning conditions may be used to support criminal proceedings. Those are good reasons for a relatively cautious approach, for example in the well established rules limiting the categories of documents which may be used in interpreting a planning permission (helpfully summarised in the judgment of Keene J in the Shepway case [1999] PLCR 12, 19—20). But such considerations arise from the legal framework within which planning permissions are granted. They do not require the adoption of a completely different approach to their interpretation.”
“Differences in the nature of documents will influence the extent to which the court may look at the factual background to assist interpretation. Thus third parties may have an interest in a public document, such as a planning permission or a consent under section 36 of the 1989 Act, in contrast with many contracts. As a result, the shared knowledge of the applicant for permission and the drafter of the condition does not have the relevance to the process of interpretation that the shared knowledge of parties to a contract, in which there may be no third party interest, has. There is only limited scope for the use of extrinsic material in the interpretation of a public document, such as a planning permission or a section 36 consent: R v Ashford Borough Council, Ex p Shepway District Council [1999] PLCR 12, per Keene J at pp 19C—20B; Carter Commercial Developments Ltd v Secretary of State for Transport, Local Government and the Regions [2003] JPL 1048, per Buxton LJ at para 13 and Arden LJ at para 27. It is also relevant to the process of interpretation that a failure to comply with a condition in a public law consent may give rise to criminal liability. In section 36(6) of the 1989 Act the construction of a generating station otherwise than in accordance with the consent is a criminal offence. This calls for clarity and precision in the drafting of conditions.”
“52. Firstly, permissions should be interpreted as by a reasonable reader with some knowledge of planning law and the matter in question. This does not mean that they are the "informed reader" of a decision letter, but equally the reasonable reader will understand the role of the permission, conditions and any incorporated documents. 53. As Lord Carnwath has said the permission needs to be interpreted with common sense. Mr Sharland points out with some justification that reasonable people may differ on what amounts to common sense. In my view references to common sense are really pointing to the planning purpose of the permission or condition. If the interpretation advanced flies in the face of the purpose of the condition, and the policies underlying it, then common sense may well indicate that that interpretation is not correct. So, in Lambeth it was plainly contrary to that purpose for the permission not to limit the sale of food items, such an interpretation was contrary to common sense once one understood the planning background. 54. Secondly, it is legitimate to consider the planning "purpose" or intention of the permission, where this is reflected in the reasons for the conditions and/or the documents incorporated. The reasons for the condition should be the starting point, the policies referred to and then the documents incorporated. This is not the private intentions of the parties, as would be the case in a contractual dispute, but the planning purpose which lies behind the condition. 55. Thirdly, where as here, there are documents incorporated into the permission or the conditions by reference, then a holistic view has to be taken, having regard to the relevant parts of those documents. This can be a difficult exercise because where, as here, the permission incorporates the application (including the Planning Statement) and the Environmental Statement and Non-Technical Summary, there can be a very large number of documents to be considered. It may be the case that those documents are not all wholly consistent, and that there may be some ambiguity within at least parts of them. In my view the correct approach is to take an overview of the documents, to try to understand the nature of the development and the planning purpose that was sought to be achieved by the condition in question. The reasonable reader would be trying to understand the nature of the development and any conditions imposed upon it. It is not appropriate to focus on one particular sentence without seeing its context, unless that sentence is so unequivocal as give a clear-cut answer. 56. Fourthly, where documents are incorporated into the permission, as here, plainly regard can be had to them. Where the documents sought to be relied upon are "extrinsic", then save perhaps for exceptional circumstances, they can only be relied upon if there is ambiguity in the condition. In my view, even where there is ambiguity there is a difference between documents that are in the public domain, and easily accessible such as the officer's report that led to the grant of the permission and private documents passing between the parties or their agents. 57. The Court should be extremely slow to consider the intention alleged to be behind the condition from documents which are not incorporated and particularly if they are not in the public domain. This is for three reasons. The determination of planning applications is a public process which is required to be transparent. Any reliance on documents passing between the developer and the LPA, even if they ultimately end up on the planning register, is contrary to that principle of transparency. Planning permissions impact on third party rights in a number of different ways. It is therefore essential that those third parties can rely on the face of the permission and the documents expressly referred to. Finally, breach of planning permission and their conditions, can lead to criminal sanctions.”
“The justification for such resort to extraneous material is to resolve a particular inconsistency or ambiguity. That being so, it would not be proper to regard other parts of the permission free from ambiguity as open to re-interpretation in the light of the application or, indeed, other extrinsic material. Such material is only being brought into play for a specific purpose. Such recourse does not make the application or other extrinsic material part of the permission generally. Otherwise the existence of an ambiguity on a single point or word in an otherwise complete and clear permission would mean that the extent of the development as a whole thereby permitted could be cut down by the application. That would be contrary to the general rule spelt out many years ago in Miller-Mead and endorsed by the Court of Appeal recently in Slough Borough Council v. Secretary of State for the Environment. Moreover, any such exception to a general rule ought to be narrowly construed.”

“(1) Where a local planning authority consider it necessary or expedient for any actual or apprehended breach of planning control to be restrained by injunction, they may apply to the court for an injunction, whether or not they have exercised or are proposing to exercise any of their other powers under this Part. (2) On an application under subsection (1) the court may grant such an injunction as the court thinks appropriate for the purpose of restraining the breach.”
