"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."
"The following operations or uses of land shall not be taken for the purposes of this Act to involve development of the land . . . (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."
"Subject to the provisions of this Order, where a building or other land is used for a purpose of any class specified in the Schedule, the use of that building or that other land for any other purpose of the same class shall not be taken to involve development of the land."
"A use which is included in and ordinarily incidental to any use in a class specified in the Schedule is not excluded from the use to which it is incidental merely because it is specified in the Schedule as a separate use.
"Use for the carrying on of an industrial process other than one falling within class B1 above."
"Industrial process means a process for or incidental to any of the following purposes -- (a) making of an article or part of any article (including a ship or vessel, or a film video or sound recording); (b) the altering, repairing, maintaining, ornamenting, finishing, cleaning, washing, packing, canning, adapting for sale, breaking up or demolition of any article; or (c) the getting, dressing or treatment of minerals in the course of any trade or business other than agriculture, and other than a use carried out in or adjacent to a mine or quarry . . . "
" . . . the making of any material change in the use of any buildings or other land."
"Briefly, coal and manufactured fuels are delivered to the site in bulk by road and some may initially be stockpiled. The mine coal which forms approximately 75 per cent of the input is screened and the smaller elements are mechanically loaded into bulk carriers for delivery to commercial customers, primarily National Power. Larger size material is recovered from this mine coal by screening, graded, sometimes washed, and stockpiled separately for domestic use. Other kinds of coal and manufactured fuels are also delivered directly to the site from a variety of sources and some of this is blended with the larger products of the mine coal. The resulting materials are loaded into hoppers, from where they are either bagged up or loaded directly into lorries for local delivery. Some of this kind of material is processed through a bagging plant where it is sealed into plastic bags, put on pallets and delivered to outlets such as filling stations and similar retail outlets. The activities on the site as a whole are generally supervised and controlled from the offices close to the site entrance."
"4. I have no doubt that the activities on the site include major elements of storage, distribution and activities which fall within the definition of industrial processes as set out in Article 2 of the UCO (Use Classes Order). However, that does not necessary mean that the site's use falls within either B2 (General Industrial) or B8 (storage or distribution) of the classes defined by the UCO. For the use of the site as a whole to be regarded as falling within class B2, activities such as storage or distribution would have to be ancillary to the primary use of the site for the carrying on of an industrial process. The converse would have to apply to the overall use of the site to be regarded as falling within class B8. On the basis of the information before me, I do not consider that either applies on this site. "5. This is a large site and substantial areas of it are used for the storage of materials, their processing by means such as screening, grading, and blending, and activities associated with the delivery and distribution of the finished protects. Furthermore, each of these three general categories of activity are major ones, and are essential to the success of the enterprise as a whole in both functional and commercial terms. In view of the level of processing that takes place, I do not consider that the overall use of the site falls within class B8. However, I find the arguments in this area finely balanced as to whether it should be regarded as being within class B2 or, instead, as a 'sui generis' use which is not within any of the UCO's classes. "6. I have also taken note of two other matters. Article 3(6)(g) of the UCO states that no class specified in the Schedule of Uses includes use as a yard for the storage or distribution of minerals. Whilst this is not a full or exact description of the use prevailing in this case it is very similar to it and to the description of the site given in the 1975 notice of planning permission. I have also considered the Land Use Gazetteer which, whilst describing uses such as 'coal grading place' and 'coal mixing place' as B2, classifies others such as 'coal yard' and a 'coal merchant's yard' as 'sui generis' uses. Taking these matters into account along with all the other relevant factors and arguments, my conclusion is that the use of the appeal site is a 'sui generis' use which does not fall within any of the classes of the UCO."
"7. The use proposed by the appellants is described as use of part of the site for a materials recycling facility. The area concerned is not defined but I have no doubt that it will be a substantial proportion of the site. Their intention is that general waste materials will be delivered to the site by road and these will then be sorted to recover saleable materials such as scrap metals or intact building products. Some material such as concrete will be crushed and screened. Timber will be chipped, and papers and cardboards will be baled. There would also be some recovery and blending of soils and soil substitutes for subsequent sale. All of the re-usable products, estimated by the appellants to be about 65 per cent of the total volume of materials entering the site, will be sold on and the unsaleable residue will be disposed of to licensed landfill sites. There would be no incineration or chemical treatment of materials. It is anticipated that a portal frame building would be needed for much of the processing and there would also be external storage bays. "8. Again I accept that the proposed activities on the site would include substantial elements of storage, distribution and activities which fall within the UCO's definition of industrial processes. However, in this instance it seems clear to me that the primary use of this site would be as a materials recycling facility and that any elements of storage, processing or distribution would be ancillary to that primary use. I turn therefore to consider the nature of use of the area as a materials recycling facility. "10. A materials recycling activity also involves a similar group of three main activities but the overall use is crucially different from the use I have referred to in the previous paragraph. In the latter, the materials brought to the site are valuable in themselves and have to be purchased. In the former, they are usually waste materials and a recycling company is almost always paid to take them away. In my interpretation the use proposed in this case would constitute the provision of a disposal service for which customers pay a charge as opposed to a straightforward purchase, adaptation and sale operation. "11. I note that the Land Use Gazetteer classifies many uses which deal with the transfer or recycling of waste as 'sui generis' uses. I have also taken into account that there are fundamental differences between materials classified as wastes and minerals, both physically and as perceived by many members of the public. Taking into account all of the relevant factors I consider that the proposed use would not fall within class B2 but would be a 'sui generis' use outside any of the UCO classes."
"Based upon my conclusions as to the character of the existing and proposed uses, I am satisfied that the two uses would be materially different irrespective of whether the existing use is regarded as a B2 or a 'sui generis' use."
"It seems to me perfectly clear that prima facie the question of whether a change of use is a material change of use is one of degree and of fact . . . "
"It is necessary to answer two questions which are primarily questions of fact. First, what is the precise character of the established use? Secondly, what is a range of uses sufficiently similar in character to the established use to be capable of replacing the established use without involving a material change? Behind the second question lies a potential question of law in that there may be some uses of such a character that a reasonable tribunal of fact, directing itself correctly in law, must necessarily conclude that they lie within that range, or beyond it, as the case my be."
