"What is complained of in the present case is infringement of air space by a structure positioned upon a neighbour's land. The defendant has erected tower cranes on its land. Attached to each tower crane is a boom which swings over the plaintiff's land. The booms invade the air space over the plaintiffs' land. Each boom is part of the structure on the defendant's land. The tort of trespass represents an interference with possession or with the right to possession. A landowner is entitled, as an attribute of his ownership of the land, to place structures on his land and thereby to reduce into actual possession the air space above his land. If an adjoining owner places a structure on his (the adjoining owner's) land that overhangs his neighbour's land, he thereby takes into his possession air space to which his neighbour is entitled. That, in my judgment, is trespass. It does not depend upon any balancing of rights."
"NOW the landlords HEREBY LICENCE the Tenant to erect and thereafter to maintain within or about the premises of the Landlords and in positions to be approved by the Landlords [certain panels] and to display thereon advertisement posters for the period and upon the terms and conditions following ..."
"NOW the landlords HEREBY LICENCE the Tenant to service the poster panel on the side wall of 151 Battersea Park Road, London SW8 at all reasonable times but to be agreed with the Caretaker."
"The only difference between the previous state of affairs and the current state of affairs is that the current structure is sited in the ground of 149 Battersea Park Road whereas the previous one was suspended above it. The Council appears unwilling to have any regard to that fact, choosing instead simply to assert that there exists no evidence for the basic and obvious proposition that the structure has always been on 149 Battersea Park Road."
"(5) Without prejudice to any regulations made under the provisions of this Act relating to the control of advertisements, the use for the display of advertisements of any external part of a building which is not normally used for that purpose shall be treated for the purposes of this section as involving a material change in the use of that part of the building."
"(1) Regulations under this Act shall make provision for restricting or regulating the display of advertisements so far as appears to the Secretary of State to be expedient in the interests of amenity or public safety."
"(1) Subject to regulations 7 and 8, and in the case of an area of special control also to regulation 21, consent is granted for the display of an advertisement of any class specified in Part 1 of Schedule 3, subject to— (a) the standard conditions; and (b) in the case of any class other than Class 12, the conditions and limitations specified in that Part in relation to that class."
"An advertisement does not fall within this description if, during the relevant 10-year period, there has been either a material increase in the extent to which the site has been used for the display of advertisements or a material alteration in the manner in which it has been so used."
"Description 13. An advertisement displayed on a site which was used for the display of advertisements without express consent on1st April 1974 and has been so used continually since that date. Conditions and Limitations 13(1) No substantial increase in the extent, or substantial alteration in the manner, of the use of the site for the display of advertisements on1st April 1974 is permitted."
"Mr David Lambing for the appellant authority argues that had the justices addressed the issue correctly they would have found that there were two sites respectively: (a) the land adjoining 14 Tanner Street, which was purchased by the respondents; and (b) the flank wall of 14 Tanner Street itself. For my part, I would reject that contention. Such a case was not argued below and, in my judgment, there is no sufficient factual foundation for it. Of course the respondents needed permission from the owners of 14 Tanner Street to affix their hoarding, but it does not follow that the hoarding and the advertisement itself was not properly to be regarded as being within their own adjoining land. In these circumstances it seems to me highly likely that, even had the justices been given the assistance they needed and in the result directed themselves in accordance with Scotts Restaurant, they would have reached the self-same conclusion, namely that as a matter of fact the relevant site referred to the whole of the adjoining premises. After all they were also to conclude that the overall change did not involve '... a substantial alteration in the manner of the use of the site ...' and the two conclusions, to my mind, are in a real sense harmonious. In these circumstances I see no good reason why the justices' conclusion upon the matter should be labelled 'incorrect'."
"Once the site is recognised to be the whole parcel of land upon which these various advertisements, old and new, stood (as for the purposes of resolving the second issue it must be), then it seems to me that the justices' conclusions at paras 6 and 7 amply justify their factual finding on the second issue. They had, after all, visited the site in order to make themselves fully aware of its appearance."
