30 Mr Hemmings complains that the Irongates point was not foreshadowed and hence his client was not aware of the need to prove compliance with condition 9. No directions were made regarding filing of Points of Claim or Points of Defence or service of a copy of written submissions before the hearing. However, the issues were clearly articulated and the applicant has been well aware of the council's position regarding whether there has been substantial commencement for many years. The requirement for any work relied upon to be lawful is a well established principle. (See further: Coalcliff Community Association Inc v Minister for Urban Affairs and Planning and Others (1999) 106 LGERA 243).
31 It is not a matter of shifting onus whereby the council is required to establish that the work done was unlawful as a consequence of failure to comply with a condition. The issue is whether or not the work was done lawfully. Work done unlawfully under the consent cannot count as commencement to prevent lapsing of a consent (Coalcliff at [66]). The applicant has not proved on the balance of probabilities that the work of excavation occurred after condition 9 and 10 were satisfied. Mr Novarti agreed that the excavation could have occurred as early as October. That would have been in clear breach of condition 10 and hence unlawful. There is no first hand evidence one way or the other regarding compliance with condition 9.
32 The rules of evidence do not apply in Class 1 proceedings but where the Court is moved to determine legal issues in accordance with proved facts then it is appropriate to adopt the customary standards of proof applicable in civil proceedings. The applicant has the onus to prove its case. No application has been made for leave to bring further evidence in chief nor for an opportunity to bring evidence in reply to the Council's case. I propose to determine the issues on the basis of the evidence as it stands in accordance with the civil standard.
33 Assuming that the Court is prepared to infer that condition 9 was satisfied by the time the pier holes were dug and filled with concrete on the basis of Mr Hemming's submission, and that the work in that regard occurred during December 1972 before 24 December 1972, it would still be necessary to find that the work amounted to substantial commencement based on the evidence available to me.
34 The test is an objective one in the context of a proposed building effectively with nine levels including seven floors devoted to residential flats or units.
35 In Drummoyne Municipal Council v Page (1973) NSWLR 566, Jacobs P said that it is a question of degree in each case. On appeal (Drummoyne Municipal Council v Lebnan (1974) 131 CLR 350) Gibbs J (as he then was) with whom four other members of the Court agreed, while dismissing the appeal, said at 361:-
"However, to say that work has been 'substantially commenced' does not, in the natural meaning of those words, suggest that what has been done forms a large proportion of the whole work; something can be substantially commenced although it has not been substantially completed. For example, if, in the case of a large city building, work had been done that was in itself very extensive and costly, it would accord with ordinary usage to say that work had been substantially commenced, although what had been done formed only a small proportion of the whole work. The test to be applied for the purposes of s. 315 and cl. 38 (2) is whether the work or development the subject of the approval or consent has been begun by the performance of some substantial part of that work or development."
36 In Day v Pinglen Pty Ltd (1981) 148 CLR 289, the majority observed at 299 that:-
A substantial commencement involves a commitment of resources of such proportions relative to the approved project as to carry the assurance that the work has really commenced.
37 In that case the Court held that a concrete slab was not a substantial part of an approved work of six town houses.
38 The construction of the 13 piers were referable to, and as the evidence of Mr Algorry confirms, only referable to, the proposed building. Although numerically the piers observed by Mr Algorry are approximately one half of the total number proposed, taken in the context of the total building in my view they are not of such dimension that they carry the assurance that the work was really commenced. It on its face comprises a small component of the work. It was completed within a few days.
