"55. Meaning of 'development' and 'new development' "1. Subject to the following provisions of this section, in this Act, except where the context otherwise requires, 'development' means the carrying out of building, engineering, mining or other operations in, on, over or under land, or the making of any material change in the use of any buildings or other land..." "2. The following operations or uses of land shall not be taken for the purposes of this Act to involve development of the land—- (a) the carrying out for the maintenance, improvement or other alteration of any building of works which—- (i) affect only the interior of the building, or (ii) do not materially affect the external appearance of the building. "and are not works for making good war damage or works begun after5th December 1968 for the alteration of a building by providing additional space in it underground; (b) the carrying out on land within the boundaries of a road by a local highway authority of any works required for the maintenance or improvement of the road (but, in the case of any such works which are not exclusively for the maintenance of the road, not including any works which may have significant adverse effects on the environment); (c) the carrying out by a local authority or statutory undertakers of any works for the purpose of inspecting, repairing or renewing any sewers, mains pipes cables or other apparatus, including the breaking open of any street or other land for that purpose; (d) the use of any buildings or other land within the curtilage of a dwellinghouse for any purpose incidental to the enjoyment of the dwellinghouse as such; (e) the use of any land for the purposes of agriculture or forestry (including afforestation) and the use for any of those purposes of any building occupied together with land so used; (f) in the case of buildings or other land which are used for a purpose of any class specified in an order made by the Secretary of State under this section, the use of the buildings or other land or, subject to the provisions of the order, of any part of the buildings or the other land, for any other purpose of the same class; ((g) the demolition of any description of building specified in a direction given by the Secretary of State to local planning authorities generally or to a particular local planning authority.) "3. For the avoidance of doubt it is hereby declared that for the purposes of this section—- (a) the use as two or more separate dwellinghouses of any building previously used as a single dwellinghouse involves a material change in the use of the building and of each part of it which is so used; (b) the deposit of refuse or waste materials on land involves a material change in its use, notwithstanding that the land is comprised in a site already used for that purpose, if—- (i) the superficial area of the deposit is extended or (ii) the height of the deposit is extended and exceeds the level of the land adjoining the site." "191. Certificate of lawfulness of existing use or development "1. If any person wishes to ascertain whether— (a) any existing use of buildings or other land is lawful; (b) any operations which have been carried out in, on, over or under land are lawful; or (c) any other matter constituting a failure to comply with any condition or limitation subject to which planning permission has been granted is lawful, He may make an application for the purpose to the local planning authority specifying the land and describing the use, operations or other matter. "2. for the purposes of this Act uses and operations are lawful at any time if—- (a) no enforcement action may then be taken in respect of them (whether because they did not involve development or require planning permission or because the time for enforcement action has expired or for any other reason); and (b) they do not constitute a contravention of any of the requirements of any enforcement notice then in force..." "4. If, on an application under this section, the local planning authority are provided with information satisfying them of the lawfulness at the time of the application of the use, operations or other matter described in the application, or that description as modified by the local planning authority or a description substituted by them, they shall issue a certificate to that effect; and in any other case they shall refuse the application. "5. A certificate under this section shall—- (a) specify the land to which it relates; (b) describe the use, operations or other matter in question (in the case of any use falling within one of the classes specified in an order under section 55(2)(f), identifying it by reference to that class); (c) give the reasons for determining the use operations or other matter to be lawful; and (d) specify the date of the application for the certificate..." "7. A certificate under this section in respect of any use shall also have effect, for the purposes of the following enactments, as if it were a grant of planning permission—- (a)section 3(3) of the Caravan Sites and Control of Development Act 1960 ; (b)section 5(2) of the Control of Pollution Act 1974 ; and (c)section 36(2)(a) of the Environment Protection Act 1990 ." "192. Certificate of lawfulness of proposed use or development "1. If any person wishes to ascertain whether-- (a) any proposed use of buildings or other land; or (b) any operations proposed to be carried out in, on, over or under land, "would be lawful, he may make an application for the purpose to the local planning authority specifying the land and describing the use or operations in question. "2.

"3. A certificate under this section shall-- (a) specify the land to which it relates; (b) describe the use or operations in question (in the case of any use falling within one of the classes specified in an order under section 55(2)(f) identifying it by reference to that class); (c) give the reasons for determining the use or operations to be lawful; and (d) specify the date of the application for the certificate. "4. The lawfulness of any use or operations for which a certificate is in force under this section shall be conclusively presumed unless there is a material change, before the use is instituted or the operations are begun, in any of the matters relevant to determining such lawfulness." "336(1)(Interpretation) "
"1(4). In this Part of the Act the expression 'caravan site' means land on which a caravan is stationed for the purposes of human habitation and land which is used in conjunction with land on which a caravan is so stationed." "3(3). A local authority may on an application under this section issue a site licence in respect of the land if, and only if, the applicant is, at the time when the site licence is issued, entitled to the benefit of a permission for the use of the land as a caravan site granted under Part III of the Act of 1947 otherwise than by a development order." "29(1). In this part of the Act, unless the context otherwise requires-- "
"As the appellant argues, mere intensification of use does not in itself constitute a material change of use and the courts have decided this on a number of occasions as set out in the notes in the Encyclopedia (of Planning Law) at volume 2 P55.53 and in the appellant's representations. Any change, in order to constitute a material change of use by intensification, must be to a degree that amounts to a change in the character of a use. In looking at the character of this use, however, it is legitimate to take into account the impact, in planning consequences, of the change on the immediate surroundings outside the planning unit. I consider that that would include examining such matters as the appearance of the site in the landscape and its impact on the visual amenity of the area; the activity taking place on the land; the traffic generated by the use both in terms of numbers of vehicles and patterns of movement and also the effect on the immediately surrounding roads. "
"Visually I consider that four caravans and their other incidental paraphernalia and vehicles would appear discreet in the landscape but I do not consider as a matter of fact that that would be the case with eight. Viewed in the landscape the land would, in my opinion, take on a materially different character; it would clearly appear as a developed site which I do not consider would be the case if there were only four caravans."
"I am of the opinion that, as a matter of fact and degree, there would be a material change in the character of what was happening on the site if the number of caravans stationed there and occupied residentially increased from four to eight. In my view it is not just a case in general terms of double the numbers and double all the consequences. That doubling of consequences results in the site being perceived in a materially different way and all that takes place on it and immediately around it being materially different in its character." "
"Nor, in my judgment, does it assist Mr Fay to argue that the certificate specifies no particular level or intensity of activity, and, therefore, to submit that the level or intensity of activity was not a matter stated in the certificate and so was a matter on which the certificate was not conclusive. The short answer on this point is that the use was a matter stated in the certificate. Since no limit was placed upon either part of the site to be so used or the intensity of the use, the use so specified was without limit as to space within the site or intensity. Mr Fay cannot, therefore, now complain that the Secretary of State has erred in law in holding that there has been no material change of use by reason of the area of the site now employed or the present intensity of the use..." "
"It was said on behalf of the appellant that the change of use alleged in the enforcement notice (from one to four caravans) was not a material change of use. Intensification of an existing use, it was said, is not a material change of use. I do not agree. I think that a considerable increase in the number of caravans would be a material change of use. In any case it must be remember that this whole site was used as a pleasure ground with a café and one caravan. If the site is used as well for several caravans, that would be a material change of use. It would be a change from a pleasure ground to a caravan site, at least in part. This question -- of a material change of use -- has been repeatedly held to be a question of fact and degree. The Divisional Court was quite right to refer it to the Minister for decision."
"Permission to appeal will only be given where-- "(a) the court considers that the appeal would have a real prospect of success..."
"(b) there is some other compelling reason why the appeal should be heard."
"The appellant must file the appellant's notice at the appeal court within – (a) such period as may be directed by the lower court; or (b) where the court makes no such direction, 14 days after the date of the decision of the lower court that the appellant wishes to appeal."
