18 An important part of the exercise of my discretion is to uphold the legislative purpose of the integrated and co-ordinated nature of planning law (Kirby P at 340, point 4) as the Court is enforcing a public duty. An important part of that planning law system is the requirement to undertake development in accordance with development consent granted under the EP&A Act. There is no doubt that the work is unauthorised and clearly benefits the Respondents in that they gain a useable indoor and outdoor recreation space for which they do not have consent on the roof of the house. As identified by Kirby P in Sedevcic at 341, point 5:
It is only in this sense that "special" circumstances need to be established to secure a favourable exercise of the discretion provided by s 124. There is nothing in the Act by which the discretion is fettered or limited to "special cases", as Mahoney J, as he then was, pointed out in analogous circumstances in Blacktown Municipal Council v Friend (at 197). But the obvious intention of the Act is that, normally, those concerned in development and use of the environment will comply with the terms of the legislation. Otherwise, if unlawful exceptions and exemptions became a frequent occurrence, condoned by the exercise of the discretion under s 124, the equal and orderly enforcement of the Act could be undermined. A sense of inequity could then be felt by those who complied with the requirements of the Act or who failed to secure the favourable exercise of the discretion under s 124.
19 Council argued that in light of the adverse impacts demolition should be ordered. The breach is not technical, unnoticeable other than to a person well versed in the relevant law. I agree. The Council submitted there has been no unreasonable delay in bringing this action. I agree and the Respondent did not argue that there was.
