“62. In my view ‘grounds’ has, and is intended to have, a wide meaning. It is an ordinary word and its ordinary meaning is land attached to or surrounding a house which is occupied with the house and is available to the owners of the house for them to use. I use the expression ‘occupied with the house’ to mean that the land is available to the owners to use as they wish. It does not imply a requirement for active use. ‘Grounds’ is clearly a term which is more extensive than ‘garden’ which connotes some degree of cultivation. It is not a necessary feature of grounds that they are used for ornamental or recreational purposes. Grounds need not be used for any particular purpose and can, as in this case, be allowed to grow wild. I do not consider it relevant that the grounds and gardens are separated from each other by hedges or fences. This may simply be ornamental, or may serve the purpose of delineating different areas of land as being for different uses. Nor is it fatal that other people have rights over the land. The fact that there is a right of way over grounds might impinge on the owners’ enjoyment of the grounds and even impose burdensome obligations on them, but such rights to (sic) not make the grounds any the less the grounds of that person’s residence. Land would not constitute grounds to the extent that it is used for separate, eg commercial purpose. It would not then be occupied with the residence, but would be the premises upon which a business is conducted.”
“12. Whether a more prescriptive test would be desirable is, at bottom, a question of policy. We are not concerned with such questions. The only question for us is whether that is what section 116, as enacted, actually means. It is not uncommon for Parliament, even in a taxation context to use course-grained words whose outer limits are left to the courts and tribunals to work out: ‘plant’, ‘emoluments’ and ‘residence’ are but three examples.”
