"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."
"(3) 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. (4) where land on a single site or on adjacent sites used as parts of a single undertaking is used for purposes consisting of, or including, purposes falling within classes B1 and B2 in the schedule, those classes may be treated as a single class in considering the use of that land for the purposes of this order so long as the area used for a purpose falling within Class B 2 is not substantially increased as a result."
"'industrial process' means a process for or incidental to any of the following purposes: - (a) the making of any article or part of any article ..." and the rest of that does not matter. I do not think it is necessary to recite (b) or (c) either, but the article then continues: "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;"
"Prior to 1971 Torbay Farm was a conventional poultry egg production unit. At around that time Wickham Laboratories identified a demand for disease free fertile poultry egg cell culture media to be used in the production of human and animal live viral vaccines. The regulatory agencies require the culture media, which includes the cells within the 'chorio-allantoic' membrane of the egg's embryo, to be produced free from specific pathogens. 3. Buildings E and F were converted into sealed isolator units for the production of fertile 'Specific Pathogen Free' (SPF) eggs, with building A used for administration, building B for general maintenance, building C for quality assurance and building D for the storage and packing of eggs ready for delivery to clients. The flocks were thus housed in a fully microbiological environment, with a pressured air supply filtered to 0.003 microns and maintained at 12C ± 0.5 C. All materials entering or leaving the units passed through fumigation cells or two-way chemical dump tanks. Poultry food was specially compounded, vacuum packed and irradiated or gassed with methyl bromide. Staff entry to the units was via a complete shower and change procedure, and cooking, washing and toilet facilities for the technician were provided within each isolator. 4. To ensure continuing status as a SPF flock 5% were blood tested each month in accord with the relevant protocol and each sample tested for 22 different pathogens. Further clinical examination was carried out at least once a week to verify that the birds were free from fowl-pox and signs of other infections. Any positive finding of disease meant that the entire flock could no longer be designated as an SPF flock. The cost of routine blood testing alone was some£250,000 per annum, with laboratory testing equating to 60-70% of total production costs. The eggs for vaccine purposes sold for about£1 each, with smaller numbers purchased by universities and research establishments at around£3 each."
"The parties are agreed that this does not constitute an agricultural use, and I share the view of the Inspector in 2005 that the primary use should properly be described as the production of SPF eggs through the breeding, hatching, rearing and keeping of poultry within a controlled environment. The use continued for more than 10 years without enforcement action and had therefore, in relation to that part of the Torbay Farm used for the purpose of the production of eggs (and its ancillary uses) become lawful. Although production ceased in 1999 it is common ground that the use has not been shown to have been abandoned. It is dormant and the use therefore subsists. 6. The issue in this case is whether the use falls within Class B1(c) since if it does so, a use within Class B1(b) would also be lawful."
"I deal first with the Class B1 proviso 'being a use which can be carried on in any residential area without detriment ...', since it is now agreed between the principal parties that this requirement is met..."
"Turning to the process which took place, this focused on the production of the SPF eggs, with the chorio-allantoic sac of the incubated embryos to be used, off site, as a live cell media in the production of vaccines. The fundamental purpose of these SPF eggs was for vaccine production, and this was the only site in the UK supplying such eggs. In the terms, however, of subsection (a) of the UCO interpretation of industrial process this process, despite being carried out in a fully barriered microbiological environment, cannot to my mind be considered in itself as the 'making' of an article. The eggs were produced rather through the natural production activity of breeding, incubation, hatching, and rearing, albeit in an environment that was managed in a particular way with the aim of achieving and maintaining a disease free flock. 10. I appreciate that the document introduced by Mr Hardy which, amongst other things, regulates SPF egg media production, the 'Orange Guide', speaks throughout of 'manufacturing'. Paragraph 34 of Annex 5, for example, under the heading of 'Manufacture of Immunological Veterinary Medicinal Products' refers to the 'method of manufacture' and paragraph 35 expressly refers to eggs from SPF flocks as a 'starting material'. EU guidelines have been reviewed since the previous inquiry. There is new guidance on 'starting materials' and paragraph 1.1 states that 'manufacturing' includes 'all operations of ... production... of active substances'. Such definition, however, is wide and even though the process at Torbay Farm would have amounted to 'manufacturing' in pharmaceutical terms I share the concerns as to its application in planning terms. The word is not used in the UCO. 11. The judgment in Powell v the SSE and Maidstone BC [1992] in relation to the breeding of worms for the conversion of rabbit droppings to compost refers to a use which was 'like an industrial process'. Neither Powell, however, nor in Salvatore Cumbo V SSE and Dacorum BC [1991] where it was held that milk production and the manufacture of soft cheese would be in the nature of a mixed farming and manufacture use, bear close comparison since to my mind it was the "starting material", namely the SPF egg, which was produced here and not the end product, the vaccines. Whilst it is certainly the case that regular monitoring and testing, including the candling, described in detail by Mr Dyer, was essential in the requirement for constant quality and maintenance of SPF status, the primary purpose on the appeal land was the production of the SPF eggs. The human intervention was to prevent interference by pathogens."
"Be that as it may, the UCO definition of industrial process means a process for 'or incidental to' the making of any article. The SPF eggs as a matter of fact and degree were produced for, and were thus incidental to, the vaccine production which took place elsewhere and by others. Notwithstanding that these eggs were fit for human consumption there is no evidence that the eggs were produced for any other purpose than the vaccines. Up to around one million eggs per year were sold to companies including such as The Welcome Foundation, Intervet and Glaxo Speke, and to the Central Veterinary Laboratories, Weybridge, University Research Departments and others. The production of vaccines as an industrial process is not in question. 13. Although mindful of the Council's view that the mining of coal for example would be incidental to the production of tyres, it is pertinent to note that the UCO imposes no geographical limit on where the process has to be or who has to carry it out. Whilst the word "site", moreover, has a distinct definition for the purposes of the Order, the word is not used in the interpretation of 'industrial process' and neither is it used in Business Class B1. As incidental to the vaccine production the use, as a matter of fact and degree, amounted in my view to an 'industrial process' in the terms of the UCO. I conclude that the lawful use thus falls within Class B1(c). It must follow that permitted development rights would allow a change to Class B1(b) use."
"What, then, are the appropriate criteria to determine the planning unit which should be considered in deciding whether there has been a material change of use? Without presuming to propound exhaustive tests apt to cover every situation, it may be helpful to sketch out some broad categories of distinction. First, whenever it is possible to recognise a single main purpose of the occupier's use of his land to which secondary activities are incidental or ancillary, the whole unit of occupation should be considered. That proposition emerges clearly from G Percy Trentham Ltd v Gloucestershire County Council[1966] 1 WLR 506 …"
