...
2. A declaration that the Respondent has breached its duty of care to the Applicant pursuant to Section 177 of the Conveyancing Act and that as a result pursuant to Section 180(4)(f) of the Local Government Act the Court makes the following mandatory injunctive orders against the Respondent:
a. The Respondent shall design and undertake, in accordance with professional geotechnical engineer, hydraulic engineer and structural engineer advice, work to the unstable Northern Beaches Council land being Lot 52 DP 788811 (known as Public Reserve Collaroy Parkes Road) ("Lot 52") as identified in the GHD Report to Warringah Council dated 18 October 2011 (ref 21/20906/BA904) sufficient to:
(i) provide a long term solution to establish an acceptable level of slope stability to Lot 52 and the fill embankment located thereon;
(ii) ensure the instability of Lot 52 and the fill embankment located thereon does not again adversely impact the southern boundary zone and associated residential infrastructure at 118B Parkes Road.
b. The Respondent shall design and undertake, in accordance with a professional geotechnical engineer and structural engineer advice, work to the boundary of Lot 52 and 118B Parkes Road sufficient to:
(i) repair damage to the southern boundary zone and associated residential infrastructure at 118B Parkes Road and SP78825 caused by the instability and landslip/failure of Lot 52 and;
(ii) provide a long term solution for an acceptable level of stability to the boundary of 118B Parkes Road and SP78825 following the landslip/failure of Lot 52.
(iii) reinstate the land and buildings to 118B Parkes Road to the condition that it [sic] they were in prior to the Respondent's breach of s177 of the Conveyancing Act withdrawing support.
Alternatively:
c. The Respondent shall:
(i) retain Lot 52 by installing rock fall mesh backed by erosion control matting and anchored to bedrock by galvanised or double corrosion protected steel dowels in accordance with professional geotechnical engineer and structural engineer advice and design;
(ii) clear up the stormwater pipes to Lot 52, including pipes and pits feeding inappropriate overflow onto 118B Parkes Road and reinstate the outlet downturn (drainage channel) in accordance with professional hydraulic engineer's advice and design.
(iii) reinstall the batter to Lot 52 and to 118B Parkes Road and construct a retaining wall system to the boundary of 118B Parkes Road sufficient to retain the associated residential infrastructure at 118B Parkes Road in accordance with professional geotechnical engineer and structural engineer advice and design and to reinstate the land and buildings to 118B Parkes Road to the condition they were in prior to the Respondent's breach of s177 of the Conveyancing Act withdrawing support.
5. An order pursuant to Section 181 of the Local Government Act that the Respondent pay the Owners Strata Plan 78825 for:
a. any investigative work and reinstatement work carried out by the Owners Strata Plan 78825 as a consequence of the NBC September Orders or the Amended Orders made by this Court.
b. expert and legal fees incurred by the Owners Strata Plan 78825 as a consequence of the NBC September Orders or the Amended Orders made by this Court.
5.5 Section 177 and Part 3, Schedule 4A of the Conveyancing Act 1919 (NSW) is also relevant to this appeal.
5.6 Section 5B of the Civil Liability Act 2002 (NSW) is also relevant to this appeal.
5.7 The Applicant seeks a mandatory injunctive order be made against the Respondent pursuant to Section 180(4)(f) of the Local Government Act and Section 9.46(1) and 9.46(2)I of the Environmental Planning and Assessment Act as a result of the Respondent's breach of s 177 of the Conveyancing Act.
5.8 Section 35, 36E, 36J and 53 of the Local Government Act 1993 is also relevant to this appeal.
...
10. The Respondent has breached its duty of care to the Applicant pursuant to Section 177 of the Conveyancing Act 1919 in that it has:
a. allowed Lot 52 to erode and destabilize to an extent that it failed to support the land on 118B;
b. omitted to undertake stabilising works to Lot 52 despite being notified of the instability of Lot 52 and the risk of damage to 118B in the GHD Report dated 18 October 2011 and the Richard Weber Engineer report dated 27 July 2011;
c. In the circumstances and having regard to GHD 2011 opinion and recommendations as summarised in Para 8 above, the Respondent should have taken precautions against the foreseeable risk of harm to the Applicant's land, however the Respondent:
(i) did not address the Applicant's request to stabilise Lot 52;
(ii) omitted to undertake stabilising works to Lot 52 despite being notified of the instability of Lot 52 and the risk of damage to 118B in the GHD Report dated 18 October 2011 and the Richard Weber Engineer report dated 27 July 2011;
(iii) required the Owners Corporation to implement a long term solution, however any works were to be contained within the Applicant's boundary, which was not a recommendation of GHD 2011;
(iv) downplayed the risk of further harm by selectively using information "cherry-picking" from the GHD 2011 in the letter sent to the Applicant dated 2 October 2011.
d. The Respondent disregarded Douglas Partners' expert opinion in the report on the landslide Landslip Assessment 118B Parkes Road, Collaroy Plateau dated 24 June 2022 despite Douglas Partners advising remediation measures in order of priority:
(i) Reinstatement of stormwater pipes at the rear of the Applicant's property.
(ii) Retaining of the fill slope 'probably by use of rock-fall mesh backed by erosion control matting and anchored into bedrock by galvanised or double corrosion protected steel dowels'.
(iii) Clearing of the Respondent's stormwater pipes and reinstatement of the outlet downturn apron.
(iv) Retaining structures (if constructed) founded on rock requiring relatively deep piles or similar.
e. The Respondent disregarded the expert geotechnical opinion already obtained prior to GHD 2022, and incorrectly and unreasonably gave precedence to GHD 2022 in the issue of the Order despite the fact that:
(i) the author of GHD 2022 did not attend the site and did not investigate damage to 118B and Lot 52;
(ii) the author of Douglas Partners 2022 reports attended the site in March and again in June 2022 and described both causation and remediation measures;
(iii) the author of GHD 2022 has not made recommendations consistent with either GHD 2011 or Douglas Partners 2022.
f. The Respondent acquired Lot 52 after subdivision in 1986, after the fill had been placed on the slope. The Respondent subsequently failed to:
(i) remove the fill from the slope
(ii) assess, plan for and manage the landslip risk to subsequent owners of 118B Parkes;
(iii) advise the author of GHD 2011 about the circumstances and extent of the fill on Lot 52 prior to 118B development;
(iv) advise the Applicant about the circumstances and extent of the fill on Lot 52 after the 2011 slump;
(v) advise Engineers investigating the cause of the 2022 landslide about the existence and extent of the fill on Lot 52;
(vi) advise the author of GHD 2022 of the circumstances and extent of the fill on Lot 52 prior to 118B development.
g. The Respondent has allowed its land to be not safe for the general public in that:
(i) the 2022 landslide has exposed the first generation of fill consisting of concrete, bricks and rusted metal;
(ii) the 2022 landslide has exposed the steep gully adjacent to the stormwater easement and directly below the Applicant's visitors carpark;
(iii) the Respondent's stormwater easement is degraded with disaggregated boulders and shotcreting, and weed infestation;
(iv) unstable fill and boulders have not been stabilised by the Respondent.
h. The Respondent does not have a Reserve Action Plan (RAP) for Lot 52 as recommended in the Generic Bushland Reserves Plan of Management 2009:
(i) The Respondent has no plan to address the landslip hazard on Lot 52 even in the face of changing pressure caused by climate change;
(ii) The Respondent has no plan to manage the increasing volume of water from Parkes Rd through the easement discharging onto Lot 52, which poses further risk of landslip;
(iii) The Respondent has no plan to restore areas of erosion, in particular degraded areas in the stormwater easement channel and the natural watercourse below;
(iv) The Respondent has no plan to address the threats to native biodiversity caused by the instability on Lot 52;
(v) The Respondent has no plans to regenerate the native bushland on Lot 52 to assist landslip risk mitigation.
11. The Respondent's breach of s 177 and the instability and landslip to Lot 52 was the cause in full or in part to the instability and structural inadequacy to 118B.
12. The Respondent has breached the terms and conditions of the NBC 2m Easement to Drain Water over 118B in that it has:
a. failed to construct, repair and maintain pipes, channels and ditches in the easement;
b. caused the concentration of water and nuisance to 118B;
c. caused the ground of 118B to be eroded by water and the respondent's stormwater;
d. caused the ground of 118B to be saturated by the respondent's stormwater causing it to slump and fail;
e. become liable to the Applicant in nuisance and breach of the terms and conditions of the easement as a result of Para (a)-(d) above.
13. The Respondent's breach of the terms and conditions of the NBC 2m Easement to Drain Water was the cause in full or in part to the instability and structural inadequacy to 118B.
14. As a result of instability and structural inadequacy being caused to 118B by the Respondent and its:
a. breach of Section 177 of the Conveyancing Act;
b. breach of the terms and conditions of the NBC 2m Easement;
c. negligence and nuisance;
in accordance with Section 181 Local Government Act an order should be made awarding the Applicant compensation for all expenses incurred by the Applicant as a result of the NBC September Order as the NBC September Order is unreasonable as detailed in Para 10, 11, 12 and 13 above.
15. Further and in the alterative as a result of the Respondent's [sic] breach of its duty of care, negligence and nuisance detailed in Para 10, 11, 12 and 13 above, it is appropriate for the Court to make mandatory injunctive orders pursuant to Section 180( 4 )(f) of the Local Government Act and Section 9.46(1) and (2) of the Environmental Planning and Assessment Act against the Respondent requiring the Respondent to reinstate support to 118B and to rectify the damage caused to 118B by Lot 52and/or the Respondent's negligence as follows:
That within 6 months of this order:
a. The Respondent shall design and undertake, in accordance with professional geotechnical engineer, hydraulic engineer and structural engineer advice, work to the unstable Northern Beaches Council land being Lot 52 DP 788811 (known as Public Reserve Collaroy Parkes Road) ("Lot 52") as identified in the GHD Report to Warringah Council dated 18 October 2011 (ref 21/20906/BA904) sufficient to:
(i) provide a long term solution to establish an acceptable level of slope stability to Lot 52 and the fill embankment located thereon;
(ii) ensure the instability of Lot 52 and the fill embankment thereon does not again adversely impact the southern boundary zone and associated residential infrastructure at 118B Parkes Road.
b. The Respondent shall design and undertake, in accordance with a professional geotechnical engineer and structural engineer advice, work to the boundary of Lot 52 and 118B Parkes Road sufficient to:
(i) repair damage to the southern boundary zone and associated residential infrastructure at 118B Parkes Road and SP78825 caused by the instability and landslip/failure of Lot 52 and;
(ii) provide a long term solution for an acceptable level of stability to the boundary of 118B Parkes Road and SP78825 following the landslip/failure of Lot 52.
(iii) reinstate the land and buildings to 118B Parkes Road to the condition that it they were in prior to the Respondent's breach of s 177 of the Conveyancing Act withdrawing support.
Alternatively:
c. The Respondent shall:
(i) retain Lot 52 by installing rock fall mesh backed by erosion control matting and anchored to bedrock by galvanised or double corrosion protected steel dowels in accordance with professional geotechnical engineer and structural engineer advice and design:
(ii) clear up the stormwater pipes to Lot 52 including pipes and pits feeding inappropriate overflow onto 118B Parkes Road and reinstate the outlet downturn (drainage channel) in accordance with professional hydraulic engineer's advice and design.
(iii) reinstall the batter to Lot 52 and to 118B Parkes Road and construct a retaining wall system to the boundary of 118B Parkes Road sufficient to retain the associated residential infrastructure at 118B Parkes Road in accordance with professional geotechnical engineer and structural engineer advice and design and to reinstate the land and buildings to 118B Parkes Road to the condition they were in prior to the Respondent's breach of s177 of the Conveyancing Act withdrawing support
(1) The Respondent is the landowner and the land manager of Lot 52;
(2) There is no doubt that the fill embankment on Lot 52 (Fill) is unstable and has eroded and slipped over a long time, it being 50 years since it was placed on the slope;
(3) Water acting on this Fill has caused Lot 52 to slip in at least four documented events;
(4) Australian Geomechanics GeoGuides for slope management and maintenance referred to in E10 Warringah LEP 2011 advise of the critical part that water plays in relation to landslide occurrence and provides guidelines for risk assessment; and
(5) Warringah LEP 2011, SEPP 19 Bushland and ss 35, 36E, 36J and 59A of the LG Act all govern the management of the land and the stormwater easement on Lot 52, for which the Respondent is solely responsible.
(a) Although s 16(1A) amplifies to some extent the jurisdiction of the Land and Environment Court, it operates only in relation to a matter which is ancillary, that is, incidental, accessory or auxiliary. Such matters within the Court's ancillary jurisdiction are matters which "must be resolved as part of an accessory or ancillary subservient function in the course of determining the matter within jurisdiction"; and
(b) Section 16(1A) does not operate to confer jurisdiction on the Court in relation to a matter which is separate to and independent of the matter properly within jurisdiction, such as a claim for damages for tort or trespass.
[20] In NA & J Investments Pty Ltd v Minister Administering Water Management Act 2000 [2011] NSWLEC 51; (2011) 181 LGERA 166 Craig J relevantly said (at [14] - [18]):
...
18 When the jurisdiction of the Court to entertain a particular cause of action is challenged, the Court is required to satisfy itself that it has jurisdiction before proceeding further with the hearing of the proceedings (R v Federal Court of Australia; Ex parte WA National Football League (1979) 143 CLR 190 at 215 per Gibbs J; National Parks & Wildlife Service v Stables Perisher Pty Ltd (1990) 20 NSWLR 573 at 585; 71 LGRA 286 at 297 per Kirby P). Moreover when that question is raised, it is incumbent upon the party invoking the Court's jurisdiction to demonstrate that such jurisdiction exists (Owners of Shin Kobe Maru v Empire Shipping Co Inc (1994) 181 CLR 404 at 426; Meehan v Commissioner of Police [1999] NSWCA 292; (1999) 47 NSWLR 284 at [4]).
