The words 'land appurtenant ' used in section 4 (9) takes us to its connotation as defined in section (2) (g) (i) and (ii) which may be extracted thus: "(g) 'land appurtenant ', in relation to any building, means (i) in an area where there are building regulations, the minimum extent of land required under such regulations to be kept as open space for the enjoyment of such building, which in no case shall exceed five hundred square metres; or (ii) in an area where there are no building regulations an extent of five hundred square metres contiguous to the land occupied by such building, and includes, in the case of any building constructed before the appointed day with a dwelling unit therein, an additional extent not exceeding five hundred square metres of land, if any, contiguous to the minimum extent referred to in sub clause (i) or the extent referred to in tub clause (ii?, as the case may be;" It may, however, be necessary to explain the terms 'land appurtenant ' or 'other land ' as used in section 4 (9) and section 2(g) (ii) as a wrong interpretation of these terms by the High Court has made confusion worse confounded.
