24 In what follows I set out my findings on the evidence on the issues raised for my consideration.
i Masonry wall
25 I am satisfied I can make findings, as I do, in favour of the Applicants on this issue. The wall, I am satisfied, was built without a building permit. That, in itself, is a serious matter but I consider that the wall has been left in an unsafe or unstable condition or has been left in a condition where its safety and stability cannot be properly determined which, in itself, is unsatisfactory and of concern. As such it may well be dangerous. Because of serious doubts over its long-term prospects, expressed to me in evidence, I am satisfied the only reasonable course to adopt is to demolish it. See Bellgrove v Eldridge [1954] HCA 36; (1954) 90 CLR 613.
26 I accept that the wall was constructed so as minimize damage from and to tree roots in and after pool construction. The tree in question is a poplar tree, see iii below. Although the Applicants have paid $4,300.00 for the wall's construction no variation has ever been signed by them. I comment on this defence later.
27 I agree with the evidence of Mr Plant, who impressed me, that it is indeed a serious matter to construct a footing for a wall without a building permit and inspections. Had a permit been obtained, there would have been mandatory inspections taking place in compliance with legal requirements. In that way the safety and stability of the wall could have been ensured. I cannot accept any explanation, sought to be proffered, that obtaining a permit was the responsibility of the Applicants. This appeared to be the purport of the evidence of Mr Matthew Keyhoe, at one point.
28 It follows that I cannot agree with the Respondents' submissions that, in regard to the wall, the Applicants have not discharged their burden of proof. The Respondents, however, go further and submit that "[the] wall is structurally sound". They submit that no evidence was lead to suggest otherwise. They point to the evidence of Mrs Brien (given in June 2005) that the wall has not shifted and they refer to the evidence of Mr Plant during re-examination (on 20 December 2005) that the wall appeared to be in very good condition - solid and performing well.
29 I cannot agree that this was the main purport of Mr Plant's evidence as a whole which, in my view, was to the effect I have mentioned above in paragraph 27. I am not persuaded I should place any reliance on the evidence of Mrs Brien insofar as it asserts expert opinion of a geo-technical or engineering or building kind. Nor, in my view, should I accede to a proposition, if it was put, that, if the wall is defective, it is something which is due to her agreement over the positioning of it. She is the house owner - or one of them - and is not equipped, in my view, except in a most general (untechnical) way, to express a view about where a wall should be positioned.
30 I have noted the evidence of Mr Green and Mr Calway regarding the alleged depth of the footings. I was not persuaded that their evidence was as carefully given as it might have been. In any event, though, I am not satisfied they are sufficiently expert enough to speak about whether the wall was well-founded or not.
31 I consider I am entitled to find on the evidence, having regard to the probabilities, that the wall in question is defective. It is now, or may be in time, a hazard. I note that the Applicants have young children.
32 I consider, in consequence, I am entitled to find the First Respondent liable for breach of s8 of the Domestic Building Contracts Act 1995. I note, in any event, as I pointed out earlier, that the First Respondent admits it was a term of its contract with the Applicants that it perform its works with due care and skill. I consider that term has been breached in the construction of the wall. I shall have more to say about the position of the Second Respondent, below.
33 As a result I am satisfied the Applicants have suffered loss and damage - representing the cost of removing the footing and replacing the wall. For, at the moment, the Applicants have a house with building works on it for which no permit has been obtained. Premises cannot be sold in such circumstances it is pointed out to me.
34 I am satisfied I should assess their loss and damage in the sum claimed of $32,037.00 based on the reports of Faulkner Lees Constructions. I see such figures, based on the evidence, including that of Mr Lees in particular, as fair and reasonable and warranted, as the only reasonable alternative open.
35 I do not regard the evidence of the Respondents as materially detracting from the proper assessment of the figure involved as that which I have assessed.
