Salient facts
6The history of the dealings between the parties relevant to the issue currently before the Court is somewhat complex. Some of that history will be referred to later in these reasons. However, at the risk of oversimplification, the following facts can be identified as being of central importance.
7By-law 36 made in 2008 provides:
"The proprietor for the time being of Lot 3 shall be entitled to the exclusive use and enjoyment of that part of the common property space (herein called the balcony) extending no further than the width of the lot and extending no further out than 3000mm from the exteriors of the South common property wall subject to the following conditions ..."
8On 15 June 2011 Waverley Council issued a notice of determination of a development application (DA 697/2010) in respect of the construction of balconies to the rear of the building. Condition 7 of the approval provided that the building work including demolition must not be commenced until:
"(a) a Construction Certificate has been obtained from Council or an Accredited Certifier in accordance with Section 81A(2) of the Environmental Planning and Assessment Act, 1979; and
(b) a Principal Certifying Authority has been appointed and Council has been notified of the appointment in accordance with Section 81A(2)(b) of the Environmental Planning and Assessment Act, 1979 and Form 7 of Schedule 1 of the Regulations; and
(c) Council is given at least two days Notice in writing of the intention to commence the building works.
9Condition 16 of the approval provided for certain fire safety upgrade works to be undertaken.
10On 19 December 2011 various resolutions were passed by the Owners' Corporation either pursuant to s 52 of the Strata Schemes Management Act 1996 (NSW) ("the Act") for the benefit of particular lots, or pursuant to s 65A of the Act for the purposes of improving or enhancing the common property. Included amongst the resolutions was a resolution, passed pursuant to s 65A, for special by-law 40 which provided:
"1. For the purpose of improving or enhancing the common property, the Owners Corporation shall carry out the Works ...
"Works" means the following works to be undertaken by the Owners Corporation:
(a) The removal of existing stairs on the southern side of the building;
(b) The removal of an existing timber balcony on the southern side of Lot 4;
(c) The construction of six balconies on the southern side of the building adjacent to Lots 1 to 6, with the depth of each balcony to extend 3.5 metres from the rear of the building ...;
(d) The construction of near [sic - rear] stairs on the southern side of the building to provide access to Lots 1 and 2 only
all in accordance with drawings ... prepared by Martin and Spork Pty Limited ... and the terms and conditions of development approval DA697/2010 issued by Waverly Council on 15 June 2011, as amended by letter from Waverly Council dated 25 October 2011;
and all ancillary fixings, flashing and guttering."
11At about the same time, the plaintiff commenced proceedings in this Court seeking injunctions to prevent the carrying out of those works. The plaintiff obtained some interlocutory relief from Slattery J, which was later varied by Ball J. The plaintiff then sought the dissolution of an order which had been made by Ball J on 16 February 2012.
12That application came before White J on 23 March 2012. The plaintiff withdrew the application during the course of the hearing, after accepting an offer which was contained in an email from the defendants' architect, Mr Spork, to the plaintiff dated 14 March 2012. This offer was made in the immediate context of a controversy over whether certain fire protection measures (the installation of new fire rated ceilings) should be permitted to be undertaken. One consequence of the carrying out of the fire safety work was that the applicant would no longer have direct and unobstructed access to the stairs at the rear of the building. Relevantly, the email from Mr Spork stated:
"4 ... New fire rated ceilings cannot be installed without the removal of the old internal staircase, and the fire separation between Units 3 and 4 cannot be completed without the construction of the new section of brick wall as shown in the approved plans. The internal timber walls separating your unit from the rear foyer must be removed in order to complete the new ceiling over it. You have been offered the option of the installation of a new door direct from your unit onto the existing external landing, or alternatively, your existing internal wall can be re-constructed after the ceiling has been installed, but note that the new brick wall section will significantly obstruct the existing door opening onto the external landing. Please advise us of which option you prefer."
13After the withdrawal of the application, counsel for the plaintiff, Mr Cohen, made further submissions to White J on the issue of costs. In the course of those submissions White J asked whether the new door was to be built as an interim measure or as a final measure. Mr Cohen responded, as is recorded on page 32 of the transcript:
"Is interim in this sense, the development is seen in the context of other developments going ahead, which are disputed, being the removal of the fire stairs and putting up of balconies. Ultimately, if that does not go ahead then it will become permanent but in the meantime it is an interim solution."
14There is some dispute as to the circumstances in which the offer came to be accepted on that day, but I do not think that it is necessary to discuss that aspect of the matter let alone express any views about it. The salient point is that the offer was accepted, and on that basis the plaintiff withdrew her application.
15White J, in a judgment delivered ex tempore on that day, stated at [2]:
"At what I trust would have been very close to the conclusion of submissions, counsel for the plaintiff advised me that the plaintiff did not wish to pursue the application because she accepted an offer made by Mr Spork, which I understand is made on behalf of the defendant, that the defendant as part of its works to be commenced next week, would install a new door on the southern boundary of her unit direct from her unit onto the existing external landing."
16His Honour continued at [9]:
"... It is not clear what the plaintiff intended to convey by her suggestion that the installation of a new door be an interim measure, although it is to be seen in the context of other developments that are disputed. The proposal, as I understand it, from the defendant, for the relocation of the door, would involve the final relocation of the door, at least so far as the defendant's obligations would be concerned."
17The doorway the subject of the agreement was in fact constructed in mid 2012.
18The final hearing of those proceedings was heard by Ball J, who gave judgment on 4 June 2012. His Honour found that certain special by-laws passed on 19 December 2011 were invalid because they were not passed in accordance with s 52 of the Act (which provides for the consent of relevant lot owners to be obtained). However, Ball J upheld the validity of special by-law 40, referred to earlier, which provides for the carrying out of works for the construction of balconies on the southern side of the building. The plaintiff accepts that position.
19In April 2013, the Waverley Council expressed views that the rear stairs were "non-compliant in relation to the Council's Fire Safety Order and Fire Safety Audit report, that they "required rectification", and needed to be upgraded.
20On 29 August 2013 a special resolution of the Owners' Corporation was passed pursuant to s 65A of the Act for special by-law 46. It provides:
"1. For the purpose of improving or enhancing the common property, and complying with fire safety requirements imposed by the local Council, the Owners Corporation shall carry out the Works ...
"Works" means the following works to be undertaken by the Owners Corporation:
(a) The removal of the existing external stairs at the rear of the building; and
(b) Bricking up the opening in the rear wall of the building left by the removal of the stairs, and making good the brickwork to match the external appearance of the existing rear wall of the building."
21On 3 January 2014 a resolution of the Owners' Corporation was passed to the effect that a tender of $48,400 including GST be accepted for the engagement of ACA Building Services to remove the rear stairs.
