Damages
23 Lily Homes submitted that if Mr Tonkin had the expertise of quoting for costs of demolition and laying of concrete, he ought to have prepared one himself, instead of leaving it to other (HASSARATI & Co Pty Ltd and S Terzopoulos). According to the plaintiff, neither was called to give evidence and that by using Cordell's building guide does not cloak the user as an expert.
24 Lily Homes also submitted that the assessment of damages was not reasonable. Counsel referred to a passage from James Edward Bromley & Ors v Forestry Commission of NSW [2003] NSWCA 252 at [4] where Mason P (with whom Meagher and Sheller JJA agreed) stated:
"The cases relied upon by the appellants (Evans and Parramatta City Council) do not establish that a plaintiff can automatically elect between diminution of value or restoration costs in a tortious claim against a defendant who damages land or goods. Restoration and repair costs may be a way of valuing loss, but only if it is reasonable to do so. The touchstone remains loss. In some cases reinstatement would provide an unjust enrichment rather than a negation of loss. Reinstatement must be a reasonable and proportionate response to the damage before the cost of reinstatement can be the measure of damages (see Evans at 40, Parramatta at 335E, Trindade & Cane, The Law of Torts in Australia 3rd ed, 2000 pp 554-5, Fleming, The Law of Torts 9th ed, 1998 pp 282-3, McGregor on Damages 16th ed, 1997 pp965ff)."
25 Similarly in Bellgrove v Eldridge (1954) 90 CLR 613, Dixon CJ, Webb J and Taylor J turned their minds to the question of the measure of damages in respect of a deficient building project. They held [at 617] that:
"In the present case, the respondent was entitled to have a building erected upon her land in accordance with the contract and the plans and specifications which formed part of it, and her damage is the loss which she sustained by the failure of the appellant to perform his obligations to her. This loss cannot be measured by comparing the value of the building which has been erected with the value it would have borne if erected in accordance with the contract; her loss can, prima facie, be measured only by ascertaining the amount required to rectify the defects complained of and so give to her the equivalent of a building on her land which is substantially in accordance with the contract."
