Cause of action in trespass
16 Mr Kirk's second complaint was divided into three parts. The first concerned the entitlement of each plaintiff to bring a claim in trespass. Mr Kirk said that the heart of such a claim is a legal right to possession of the land, which is to be distinguished from a licence or personal right to use land. He referred to the decision of the High Court in Western Australia v Ward (2002) 213 CLR 1 where McHugh J discussed the distinction between those rights, identifying the legal right to possession as the basis on which a lessee may bring an action for trespass to land, whereas a licensee is confined to an action in contract or some tort other than trespass to the land: at [503] to [504].
17 Mr Kirk submitted that the amended pleading fails to identify the basis on which it is asserted that both plaintiffs have a legal right to possession in the present case.
18 The original pleading alleged that BBB is the owner of the land and that it had entered into an agreement with Baseline pursuant to which Baseline had agreed to perform certain works. The pleading did not otherwise identify any right to possession of Baseline. The defendants' solicitor complained that any cause of action in trespass lay at the suit of either BBB as owner or Baseline as builder in possession, but not both.
19 The plaintiffs sought to address that issue by pleading the following terms of the building contract between BBB and Baseline:
"5 There were express terms and conditions of the Building Contract that:
a. BBB was required to do all things necessary to ensure that any access required by Baseline to carry out the Building Contract Works had been obtained and would be maintained;
b. Baseline was appointed the agent of BBB for the purpose of permitting persons to enter upon the Botany site, refusing any persons the right to enter and to exclude any persons from entering upon the Botany site and removing any unauthorised persons from the Botany site;
c. Baseline would have exclusive and uninterrupted possession of and access to the Botany Site for the purposes of performing the Building Contract Works."
20 The amended pleading also added the following allegations:
"6. On and from November 2007 Baseline was in and entitled to possession of the Botany site for the purposes of performing the Building Contract Works."
and
"9A. As at March 2008, BBB was in possession of that part of the Botany site required for the purpose of carrying out excavation required for the foundation pad footings and the installation of pilling to support the foundation pad footings, which form part of the Foundation Works."
21 The "Building Contract Works" were defined as the works Baseline had agreed to perform. The "Foundation Works" were defined in paragraph 8 which said:
"BBB engaged Frankipile (Australia) Pty Ltd. ("Frankipile") to design and construct the perimeter secant walls and related pilling works for the foundation ("the Foundation Works")."
22 The amended pleading alleges, in the alternative, that Baseline had "exclusive possession" of the whole of the site (paragraph 34A). I did not understand Mr Kirk to raise any separate complaint in respect of that allegation. It is tolerably clear that the alternative case is that Baseline had a legal right to possession of the whole, on the basis of an alternative construction of the terms pleaded in paragraph 5 of the amended pleading.
23 A difficulty arises, however, with the primary case. The term pleaded in paragraph 5(c) suggests that Baseline has a right of possession to the exclusion of BBB but one that is constrained by reference to the purpose of carrying out the "Building Contract Works". It is not clear whether those works are confined to certain physical areas of the land or certain phases of construction. Further, there is a level of tension between that term and the term appointing Baseline the agent of BBB pleaded in paragraph 5(b), which (read alone) suggests that BBB retains a legal right of possession of the site, possibly even to the exclusion of Baseline as its agent.
24 Taken in combination, the case appears to be that each plaintiff has a legal right to some possession of the site that is subject to temporal, spatial or purposive constraints. Whether, in those circumstances, a right to bring an action in trespass for wrongful entry on the land exists or is similarly constrained is not an issue that I have to determine in the present application. I think, however, that the content of the constraints will ultimately have to be better defined if the defendants are to know the case they have to meet at the suit of each plaintiff.
25 The position is complicated by the fact that Hoeben J has already heard and determined part of the original claim (based on the amended summons dated 14 April 2008) on a final basis. Counsel for the plaintiffs submitted that his Honour made findings and orders that each of BBB and Baseline were entitled to possession of the site. With great respect to him, I do not think that is quite what his Honour held. His Honour made a declaration that "the plaintiffs" are entitled to exclusive possession of the Botany site. On a fair reading of his reasons, however, it does not appear that his Honour turned his mind to the position as between the two plaintiffs. The hearing appears to have proceeded on the untested premise that, absent the direction of the Assistant Commissioner and the amending legislation, they were entitled to possession. The central issue his Honour had to decide was one of statutory construction. In my view, however, the right of possession of each plaintiff individually at the relevant times after 8 April 2008 is an element of the claim that will have to be determined. At the moment, the basis of those rights is not clear.
26 The need for clarification is apparent when Mr Kirk's next points are considered. The second part of his complaint in respect of the pleading of the claim in trespass was that it fails to identify the relevant interference with the right of possession. Thirdly, Mr Kirk complained that the pleading fails to identify how the interference has resulted in particular damage. He said that the plaintiffs have failed to grapple with the need to identify with precision "who did what wrong causing what damage".
27 In my view, there is force in that submission. The defendants need to know, for example, what works being carried out by which plaintiff on which parts of the site were stopped when police excluded them from the site on 8 April, and what loss or damage was suffered as a consequence.
28 The plaintiffs submitted that a detailed factual investigation would have to be undertaken before they could provide that information. That may be so, but it is no answer to the defendants' complaint. It is one thing for the plaintiffs to have succeeded in bringing to an end their exclusion from the site. The claim for damages raises different issues. If each plaintiff asserts that it suffered loss as a consequence of the defendants' conduct, it should be able to point with specificity to the acts of the defendants complained of, the right of possession interfered with by those acts and the particular losses caused as a result.
Contaminated fill claim
29 The third complaint related to the allegation in paragraph 38 of the amended pleading that, in undertaking the works referred to in the s 61 direction, the Director General deposited contaminated fill material that contained waste including bricks, concrete, wood, asbestos, chemicals or plastics and that he damaged the secant walls in various locations. Mr Kirk submitted that no cause of action has been identified in respect of that allegation and that it is not clear what cause of action is relied upon. He submitted that, if the allegation is intended to support a claim in negligence, the material facts alleged to give rise to a duty of care have not been pleaded.
30 It emerged from Mr Nicholls' submissions that the claim in respect of the contaminated landfill may properly be maintained as a component of the damages claimed in trespass. I do not think there is any embarrassment to the defendants from the inclusion of that claim in the pleading.
