The council's submissions
12 Mr Staunton submits that the proposed development clearly cannot be classified as "shop top housing", "cluster housing" or "integrated residential development". Accordingly, if the development is to be permissible it must fall within the definition of "group building". In this regard, the definition contains three essential elements, that is, the building must consist of "2 or more dwellings", each of the dwellings contained within the building must be "designed, constructed or adapted for use as a separate dwelling" and each of the dwellings must be of the type "which are commonly known as group houses, villa homes, townhouses, semi-detached or terrace buildings and the like". Mr Staunton submits that the proposed development includes the first two elements but submits that the third element is missing.
13 Mr Staunton submits that the words "and the like" should be construed according to the "generis rule" (R v Regos and Morgan [1947] HCA 19; [1947] 74 CLR 613), that is in order for the proposed development to fall within the type of dwellings specified it must share common and dominant features. The Macquarie Dictionary definitions of "villa", "townhouse", "semi-detached" and "terrace" reveal that each of these dwelling types have the features of being partly at ground level and not stacked one on top of another. As a matter of building construction, these dwellings are usually built side-by-side with a separate footprint on the ground, with a common wall but otherwise with no overlap. The ordinary meaning of the terms "villa" and "townhouse" are consistent with the way those terms used in the Building Code of Australia, referred to in State Environmental Planning Policy No 65 - Residential Flat Development.
14 On this basis, the proposed development is not "multi-unit housing" but a "residential flat building" and as such is prohibited within the zone.
The applicant's submissions
15 Ms Reid agrees that the development cannot be classified as "shop top housing", "cluster housing" or "integrated residential development". She however submits that the proposed development satisfies all three elements in the definition of "group building" identified by Mr Staunton, using the "generis rule". She submits that none of the categories of dwellings referred to in the definition of "group building" are defined in the LEP 1993 or the Model Provisions. Accordingly, the ordinary and plain meaning of the words must be used (Coady v JH Nelson Pty Ltd (1947) 74 CLR 629 per Dixson J at 647). It is clear from the definition of "group building" that the definition is not intended to be exhaustive, as this is made plain by the inclusion of the words "and the like".
16 Accepting that the "generis rule" applies, the common and dominant features of the kinds of development referred to in the definition of "group building" are:
o there are two or more dwellings on each building;
o each dwelling is capable of separate occupation; and
o there are some kinds of shared infrastructure, such as car parking and landscaping but not infrastructure that is essential to separate occupation (such as kitchens and bathrooms).
