DETERRENCE
48 There is a need for general deterrence in order to maintain the integrity of the construction certificate system, particularly given the council's loss of control when private certifiers are used: Canterbury City Council v Daoud [2007] NSWLEC 135 at [45]. One of the purposes of the amendments which replaced the previous building approval regime with the current regime for the granting of construction certificates under part 4A of the Act, including by accredited persons practising in the private sector, was to avoid the need for the resources of local government to be taken up in approval and supervision of development after issuing of development consent. If, as here, a local council is not appointed as the entity responsible for issuing the construction certificate, the council will generally not be in a position to know whether a developer is complying with the post development consent requirements, and, in particular, the requirement to defer commencement of building works until a construction certificate is issued. Consequently, offences of this nature may be difficult to detect and the system relies upon its observance by developers and builders and those involved in the construction process. This suggests that there is a need for sentences to serve as effective general deterrents, provided that no single offender has to shoulder an unfair burden in the attainment of the objective of general deterrence.
