Findings
22I am satisfied on the evidence of the root that the Banksia is a cause of the damage to the path. The applicant did not produce any evidence of any nexus between the other trees and the alleged damage. While it is a hypothetical possibility that roots may be involved, it is not open for me to conclude/ infer that because a root from one tree has lifted a section of concrete that this is a certainty for the remaining trees. Although I granted leave for the applicant to do some excavation, I agree with the respondents that the applicant has been aware of the problem long enough to provide any evidence he may wish to rely on.
23Similarly, I am not satisfied that the dents in the fence are as a consequence of the Banksia. In this I agree with Mr Rowse's observations. While there is a very slight lifting of the panel at its base, the effect is cosmetic and the fence is fully functional. If I am wrong in terms of causation and the tree has been a cause, the "damage" is so minor that, as a matter of discretion, no orders would be made for its repair.
24However, as the jurisdiction has been engaged for the Banksia in regards to one section of concrete path, I must consider what, if any, orders should be made. This requires consideration of relevant matters in s 12 of the Act.
25Most relevant here is s 12(h)(i) and (ii) - things other than the tree and actions of the parties.
26Having had the benefit of inspecting the removed section of concrete path, I concur with the professional opinions of the concreters, and the observations of Mr Rowse and the respondents - in particular, the thin layer of concrete and the absence of expansion joints and reinforcing. In addition, the concrete has been poured directly onto the soil beneath rather than onto an appropriate sub-grade. The soil is reportedly moderately reactive clay, that is, it shrinks and cracks when dry and expands when wet. This in itself can result in cracking of pavement. Therefore, the path and its installation are a contributing factor.
27Apart from painting the edges of the lifted section to highlight them as a trip hazard, the applicant has not taken any action to prevent or limit the damage. The respondents removed the tree when they became aware of the potential problem and have taken steps to try and settle the matter.
28When questioned as to whether the path was lifted when he purchased the property, the applicant agreed that it was but that it had lifted more during the period he has owned the property. This is relevant when considering what, if any, compensation is due. It would be unreasonable to order payment for damage that existed prior to the purchase of a property, or to pay the full cost of repairs to a higher standard (see Liang & anor v Marsh & anor [2011] NSWLEC 1026 at [33]-[35]).
29In this matter I have determined that some contribution is payable by the respondents but this will be limited to the replacement of the section of pavement removed by the applicant and under which was found the Banksia root. This section is illustrated in the photograph attached to this judgment. This is described as the partially lifted section from the yellow line to the nearest edge of the dwelling between the fence and the existing join to the right of the partially lifted section.
30Given the condition of the path, and the actions taken by the respondents to date, the respondents' contribution is limited to 50% of the cost of the replacement to a maximum of $200.00.
31On the basis that there is insufficient evidence and therefore no jurisdiction to do so, no orders will be made for any interference with any of the other trees or for any rectification of any other element of the applicant's property.
32As discussed in Hinde v Anderson & anor [2009] NSWLEC 1148, a fresh application can only be made if the circumstances have changed since the Court determined the earlier application and there is fresh evidence. The judgments in McCallum v Riodan & anor [2011] NSWLEC 1009 and Zangari v Miller (No 2) [2010] NSWLEC 1093 give some indication as to what the Court considers to be 'changed circumstances' and fresh evidence.
