Judgment (14 paragraphs)
A council takes action over an unsafe house 1Mr Martoriati's house is unsafe. He is the cause. 2Mr Martoriati is the owner and occupier of a house at 76 Wallumatta Road, Newport. On or before February 2012, Mr Martoriati excavated behind, beside and under his house. As a consequence, the house now lacks proper support. It is structurally inadequate. It is unsafe. 3Mr Martoriati has excavated the steep slope behind the house. The steep, excavated face, about 3.2 metres high, is unsupported and unstable. 4Mr Martoriati has dumped spoil from the excavation behind a log retaining wall resting against existing trees behind the crest of the excavation. The fill and the wall apply a surcharge load to the top of the excavation and a lateral load to the trees at the crest of the unsupported excavation. The excavated face together with the retaining wall and fill behind the crest of the excavation are hazards to Mr Martoriati's house. The likelihood of instability of the slope is almost certain in the short to medium term. The consequence of the instability could be a landslide behind the house or a tree falling on to the house. Either would damage the house and could imperil the lives of its occupants. 5Mr Martoriati has also dumped spoil on property of his neighbour, Ms Phillips, at 72 Wallumatta Road, Newport. The uncompacted fill has been dumped behind a low, sandstone block retaining wall and a cut timber retaining wall supported by existing trees. The fill, in a steep battered slope, rises to 1.4 metres behind these walls. The fill is unstable. Tension cracks have appeared at the crest of the fill slope. 6The local council of the local government area in which Mr Martoriati's house is located, Pittwater Council, is concerned about the instability and structural inadequacy of Mr Martoriati's land and house and the safety of Mr Martoriati and other occupants of the house. 7The Council has taken action to address its concerns. First, the Council has taken action to stop Mr Martoriati making the safety problems any worse. On 16 February 2012, the Council issued a stop work order on Mr Martoriati, under s 121B of the Environmental Planning and Assessment Act 1979 ("EPA Act"). This order required Mr Martoriati to immediately cease all unauthorised works that require prior council approval, including earthworks and clearing of vegetation. 8However, stopping further work does not solve the instability, structural and safety problems caused by Mr Martoriati's past actions. On 6 March 2012, the Council's geotechnical engineer, Mr Colenbrander of GHD Pty Ltd, had advised the Council that the likelihood of slope instability was almost certain and that urgent remedial works needed to be implemented. 9On 9 March 2012, the Council wrote to Mr Martoriati seeking his undertaking to implement specified remedial works as had been recommended by Mr Colenbrander. The Council warned Mr Martoriati that if he did not give the undertaking and implement the specified remedial works, the Council might bring legal proceedings in the Land and Environment Court to require him to do the remedial works. 10Mr Martoriati did not give the undertaking or do the remedial works. A letter dated 12 March 2012, from a person acting on behalf of Mr Martoriati, was sent to the Council's solicitors. The curiously worded letter, amongst other demands, requested the Council to "cease and desist" from its actions of seeking for Mr Martoriati to carry out remedial works on his land. 11On 13 March 2012, the Council commenced, by summons, these proceedings, in Class 4 of the Court's jurisdiction, seeking orders that Mr Martoriati take specified action to address the instability, structural and safety problems. Mr Martoriati was served with the summons. 12The Council claims that Mr Martoriati's actions are in breach of the law. First, the Council claims that Mr Martoriati has carried out works and erected structures, which involved development, without obtaining the required development consent. This is a breach of s 76A(1) of the EPA Act. Secondly, the Council claims that Mr Martoriati has failed to take the action he was required to take by an emergency order issued under s 124 of the Local Government Act 1993 to take specified action. This is a breach of s 672 of the Local Government Act. The Council seeks an order to restrain Mr Martoriati from continuing the breaches and orders to remedy the breaches of these two Acts. Finally, the Council claims that Mr Martoriati is in breach of interlocutory orders made by the Court in the proceedings that he undertake certain remedial works. 13The Council, by notice of motion, sought interlocutory orders. The motion was heard by the duty judge, Pain J, on 15 March 2012. Mr Martoriati did not appear at the hearing of the motion, although he had notice of it. Pain J made orders, including allowing the Council's geotechnical engineer to inspect Mr Martoriati's land and the house to identify any dangers, hazards and risks and the remediation or rectification works that should be undertaken to address these dangers, hazards or risks. Mr Martoriati was served with these orders of 15 March 2012. 14Pursuant to the court orders of 15 March 2012, the Council's geotechnical engineer, Mr Colenbrander, inspected Mr Martoriati's land and house on 21 March 2012. Mr Colenbrander later reported, on 28 March 2012, to the Council that the recent excavation around and under the house was unstable and had caused the house to be structurally inadequate and unsafe. Mr Colenbrander recommended immediate action be undertaken to ensure the safety of the property. The recommended action was: "4.1 A 2 m wide strip should be cleared around the crest of all ground floor excavated faces. All material currently placed or stockpiled within this zone should be moved to another part of the property immediately. Only tarpaulins and light frames to support them should be allowed in this zone, with the purpose of keeping rainwater out of the ground floor excavation. 4.2 A suitably qualified structural engineer should inspect the steel frame supporting the house within 7 days and either sign off that it is safe for human habitation or recommend remedial measures to make it safe. 4.3 The recommended structural repairs to the steel frame should be carried out within 14 days of receiving the structural engineer's recommendations. If these tasks are not undertaken within this time frame the house should be declared unsafe for habitation and the owner ordered to vacate the premises. 4.4 Once the steel frame has been made safe and a suitably qualified structural engineer has provided a certificate to that effect, then emergency earthworks should be carried out to improve the stability of the north and east faces of the ground floor excavation. The walkway slabs around the crest of the excavation should be carefully removed and the exposed excavation faces should be battered back to a slope no steeper than 60° above horizontal in EW rock and 45° in soil. Material excavated to achieve these batters should be legally disposed off-site or placed back in the basement excavation and spread in a layer of uniform thickness across the floor area. The completed temporary slopes should be covered in waterproof sheeting until a permanent retaining structure is approved and constructed. 4.5 The existing mesh, strip drains and iron sheeting on the Upper Terrace batters should be removed and the slopes covered with waterproof sheeting until a permanent retaining structure is approved and constructed. 4.6 The owner should be ordered to obtain the services of a suitably qualified geotechnical engineer to design permanent support measure to all the unsupported excavated faces on the property, including the driveway. I expect that the owners will be required to obtain Development Application approval for these structures in accordance with usual Council requirements. 4.7 The owner should be ordered to remove the log retaining wall and filling to the north of the Upper Terrace as a matter of urgency. The fill material should be legally disposed off-site or placed back into the basement excavation." 15On 29 March 2012, on the Council's motion, Pain J made further interlocutory orders that Mr Martoriati carry out the remedial works recommended by Mr Colenbrander, by 11 April 2012. Order 9 of the Court's orders of 29 March 2012 provided: "On or before 5.00pm on 11 April 2012, the Respondent conduct the following works on the Property and provide evidence to the Applicant to demonstrate compliance with this order: (a) within the zone marked in pink on the document annexed to these orders and marked Schedule A, being the area from the residence to the Western boundary and a 2 metre wide strip on the North and Eastern side of the residence (being the crest of all ground floor excavated faces), remove all materials currently placed or stockpiled so that only tarpaulins and light frames to support them remain; (b) remove existing mesh, strip drains and iron sheeting on the area marked in yellow on Schedule A (being the batter behind the area labelled "Upper Terrace" on the document annexed to these orders and marked Schedule B); (c) cover slopes on the area shaded yellow on Schedule A with waterproof sheeting until a permanent retaining structure is approved and constructed; and (d) remove the log retaining wall shaded green on Schedule A and remove the placed fill to the north of the retaining wall marked on Schedule B." 16Pain J also allowed the Council's structural engineer to inspect Mr Martoriati's land and the house to ascertain whether the steel frame that supports the house is safe and, if the frame is found not to be safe, to recommend remedial measures to make it safe. Mr Martoriati was served with the court orders of 29 March 2012. 17Pursuant to the court orders of 29 March 2012, the Council's structural engineer, Mr Berriman, inspected Mr Martoriati's land and house on 2 April 2012. Later that day, Mr Berriman reported in writing to the Council that the house was structurally inadequate in various ways. He recommended implementing various remedial measures to ensure the structural inadequacies of the house were rectified. The recommended remedial measures should be implemented in accordance with the requirements of Australian Standards AS 3600 Concrete Structures, 3700 Masonry Structures and 4100 Steel Structures. Mr Berriman recommended the following sequence of work: "● The surcharge loading at the top of the excavations must be removed; ● Provide edge protection in the form of handrails and balusters parallel to the entire perimeter of the excavation. The tarpaulins provided are totally inadequate for this purpose. Please note these handrails could be temporary or permanent structures. If temporary handrails and balusters are provided they must be replaced by permanent structures at a later date; ● All rubble and other material must be removed from the basement to provide appropriate access; ● Install temporary vertical support and bracing in the form of scaffolding to provide an appropriate level of structural stability. The positions of temporary props are to be agreed on site so that existing unrestrained props can be easily removed; ● Install properly engineered permanent footing under all steel columns and replace Acrow props with steel columns; ● Confirm structural adequacy of existing floor beams and replace beams if adequacy cannot be proven; ● Install a permanent bracing system that provides overall stability. This bracing will include horizontal and additional vertical bracing in the east and south walls; ● Construct appropriately engineered retaining walls, (reinforced masonry) along the northern and eastern sides of the basement including an appropriate drainage system that collects and discharges water into the sewer and ● A basement slab which will seal the excavation." 18Mr Berriman recommended that these remedial works be commenced without delay. Mr Berriman also recommended that the residents of the house must vacate the property and should only return when the following works have been completed: "-Removal of the surcharge as required by the first dot point; -The edges of the excavation have been protected as required by the second dot point; -All rubbish is removed from the basement as required by the third dot point; -The temporary scaffolding system is installed as required by the fourth dot point and -The civil engineering works described in 9 (a) to (e) inclusive of the Court Order issued by the Land and Environment Court case no 40251 of 2012 issued 29 March 2012." 19After receiving Mr Berriman's report of 2 April 2012, the Council issued, on 5 April 2012, an emergency order under s 124 of the Local Government Act requiring Mr Martoriati to complete, by 11 May 2012, not only the works required by order 9 of the court orders made by Pain J on 29 March 2012 but also the remedial works recommended by Mr Berriman. The emergency order required Mr Martoriati to do the following things specified in Schedule 1: "Engage the services of an appropriately experienced contractor to undertake the following work in the following sequence, commencing immediately and completing all works by 11 May 2012:
