The public interest
43 In the following discussion the terms public interest, public good and public benefit are used interchangeably.
44 As quoted in paragraph 9, cl 2(2)(b) of the Sydney Harbour REP states that, in the assessment of any proposed change for Sydney Harbour and its foreshores, the public good has precedence over the private good. Pursuant to s79C(1)(e) of the EPA Act the public interest is a matter for consideration in the evaluation of all development applications. While it is one thing to draft legislation requiring a consent authority to take into account the public interest among a host of other considerations, it is quite another (and much more difficult) to define what the public interest is in a particular case and to know what weight to give it among the factors that influence a planning decision. Since in these proceedings there are competing claims whether the renewed marina constitutes a public benefit, it is useful to discuss the nature of the public interest and the ways in which it may be taken into account in the evaluation of a development proposal.
45 A 1985 judgment of the High Court (Australian Central Credit Union v Corporate Affairs Commission South Australia 157 CLR 201-214 at 208) deals with the definition of the public, though not in the context of planning decisions but in that of a public offer made to members of a particular credit union.
The question whether a particular group of persons constitutes a section of the public for the purposes of s5(4) of the (Companies (South Australia)) Code cannot be answered in the abstract. For some purposes and in some circumstances, each citizen is a member of the public and any group of persons can constitute a section of the public. For other purposes and in other circumstances, the same person or the same group can be seen as identified by some special characteristic which isolates him or them in a private capacity and places him or them in a position of contrast with a member or section of the public.
46 The judgment concludes that members of a particular credit union are identified by a special characteristic that isolates them in a private capacity. Although there were 23,000 members, they did not constitute a section of the public.
Planning principle: discerning the public interest in development applications
47 Consideration of the public interest may usefully be broken into three steps: defining the public whose interest is being invoked; defining the benefit towards which a proposal claims to make a contribution (or from which it is claimed to detract); and making explicit the weight given to the public interest relative to other considerations.
48 "The public" is an amorphous term. Like "locality", it requires redefinition in every case. At its broadest (for example when impacts that have no borders, such as pollution are considered), the public may be all people in the world. At its narrowest, the public may be the people who live or work in a locality or a business centre or use a public facility, such as a park or a beach. At mid-level, the public may be the residents of a suburb, a local government area or a city.
49 Councils often confuse the public interest with the complaints of individual objectors. In most cases the interest of objectors is a private interest. The fact that the number of objectors is large does not, by itself, render their interest public. For the interest of objectors to be equated with the public interest, the objectors must be identifiable as a section of the public as described above. The fact that their number may be small (for example the users of a park), does not deny the public nature of their interest.
50 The next step is to make explicit the benefit to which a proposal contributes or from which it detracts. Where the benefit or detriment can be quantified, this should be done; however, not all benefits lend themselves to accurate measurement. Moreover, not all benefits are universally recognised as benefits. In the case of some benefits there is likely to be general agreement that they are benefits. For example, everyone would agree that reducing the risk of traffic accidents is a benefit. Hospitals, nursing homes and schools, whether public or private, are usually considered a public benefit. When it comes to changing a view composed of natural elements of the landscape into one dominated by man-made elements, the benefit-detriment debate becomes less clear-cut, though most people would prefer natural landscapes. However, when it is a question of a new building replacing an old one, opinions may split evenly on whether this is desirable or undesirable. Where there are competing and feasible claims whether a proposal contributes to or detracts from the public interest, there is no option for the decision-maker but to make a subjective choice between them.
51 The final and most difficult step is the ranking of the various interests. This may require weighing one public interest against another or balancing the public interest against private interests. Although only few planning instruments contain a statement that the public interest is paramount, in planning decisions, other things being equal, the public interest overrides the private interest. However, other things are rarely equal, and where a public detriment is minor, a major private benefit may take precedence over it.
52 The hardest conundrum occurs when the decision-maker must choose between competing public interests. For example, does the public benefit of a wind farm producing renewable energy justify the public detriment of covering a scenically beautiful area with turbines? In these cases decision-makers cannot avoid making value judgments but they owe it to the readers of their judgment to make the value judgments explicit.
Applying the planning principle to this case
53 It is common ground between the parties that the loss of views from the intertidal beach between the marina and the private jetty at the end of Beach Street constitutes a diminution of the public interest, in other words it is a public detriment.
54 The parties disagree, however, whether the loss of views from the ground floor of dwellings between the marina and the private jetty is a public or a private detriment. In my opinion, the loss of these views is a private detriment. The owners or occupants of those dwellings do not constitute the "public" or even a "section of the public". They are a collection of private interests.
55 There is also disagreement whether the application itself (including its absorption of eleven swing moorings) contributed to the public interest. The applicant argues that the marina, being a commercial marina open to anyone who wants to buy a berth in it, is in the public interest. The applicant finds support in this contention in the Sydney Harbour REP, which appears to favour commercial marinas over private marinas. For example, the REP defines commercial and private marinas separately and makes commercial marinas permissible in four of the eight zones used in the REP, while private marinas are permissible in just one zone. In addition, the Sydney Harbour DCP contains a statement (page 28) that recognises commercial activities within some parts of the Harbour as providing an important recreational resource and improving public enjoyment of the Harbour.
56 In support of its contention that the renewal of the marina represents a private interest, the council tendered the Articles of Association of the applicant company. Even without the Articles of Association (which seem little different from those of other private business organisations) it seems clear that the application serves a private rather than the public interest. The berths will be available for purchase under Strata title. This is no different from an apartment building. I accept, however, that a minor part of the application, the provision of disabled facilities, is in the public interest.
57 The applicant contends that the inclusion of eleven swing moorings in the renewed marina is in the public interest. This is because a boat in a marina berth occupies a tenth of the water surface of a boat on a swing mooring. The conversion of swing moorings into marina berths therefore increases the area of water available for navigation. Against this is the consideration that the visual impact of a swing-moored boat is much less than that of a boat berthed in a marina (see Figure D1 on page 69 of the Sydney Harbour DCP). Therefore if one considers ease of navigation more important than visual impact, the conversion of swing moorings to marina berths is a public benefit; while, if one adopts the opposite position, it becomes a public detriment.
58 In summary, the competing public and private interests may be defined as follows:
· view loss from the intertidal beach, which is a public detriment;
· the provision of disabled facilities in the renewed marina, which is a public benefit;
· the significant loss of views of ten to twenty dwellings behind the intertidal beach, which is a private detriment;
· the provision of improved mooring facilities for the future users of the existing marina, which is a private benefit.
59 It seems to me that the two matters that determine the fate of this application are the weight one gives to the loss of views from the intertidal beach and the balancing of the private benefit of better boat accommodation against the private detriment of view loss from the dwellings behind the intertidal beach.
60 In my opinion, the public interest of preserving the views from the intertidal beach, because of its low accessibility, should be given moderate weight. Even so, it outweighs the public benefit of providing disabled facilities in the new marina, which is likely to be used by a very small number of people.
61 The nature of the benefit and detriment greatly influences the balancing of the private interest of boat owners against the private detriment of the occupants of the affected dwellings. The interest of boat owners is to have more up-to-date accommodation for their boats. The detriment to the occupants of the dwellings is to deprive them of their water view, which is probably the amenity they value highest in their dwelling. It seems to me that better accommodation for one's boat is a convenience, whereas the loss of water views is a devastating (and, in a waterfront dwelling, unexpected) experience.
62 I am strengthened in my conclusion by Mr Chesterman's and Mr Moody's evidence, which I found persuasive, that the renewed marina is not in sympathy with the small-scale and permeable visual character of the Bay. Mrs Tudehope, together with other objectors, also conveyed this opinion.
63 Mr Bersten's evidence suggests that a new marina within the existing footprint extended by 20m would accommodate the existing 40 boats to today's requirements. From his point of view this would be suboptimal because the boats would continue to be moored in an east-west direction. More dredging would be required and possibly more seagrasses would be disturbed. The visual impact would, however, be minor and for anyone for whom the appearance of the Bay prevails over the convenience of boat owners, this would be a preferable solution.
