The Applicants' Claims
7 As at the date of settlement, the then current iteration of the applicants' pleaded case is contained in their Fifth Further Amended Statement of Claim (ASC).
8 In the proceeding, the applicants alleged that the Commonwealth was guilty of negligence in causing or being responsible for the alleged escape of equine influenza virus (EIV) from the Eastern Creek Quarantine Station (ECQS) during August 2007.
9 The Commonwealth was the lessee and controller of the ECQS. It used those premises for quarantine measures in relation to horses and other animals.
10 Before August 2007, no horse in the general Australian horse population had ever been infected with EIV. In other words, it was a "naive" population.
11 The ECQS was operated by a division of the Commonwealth Department of Agriculture, Fisheries and Forestry (now the Department of Agriculture) called the Australian Quarantine and Inspection Service.
12 The outbreak of EIV in August 2007 quickly spread throughout New South Wales, Queensland and the Australian Capital Territory. In response to that outbreak, the Government imposed restrictions on the movement of horses. These restrictions remained in place in parts of New South Wales and Queensland until 30 June 2008 and in the Australian Capital Territory until 1 July 2008.
13 The Commonwealth used the ECQS for (amongst other things) post-entry animal quarantine for imported horses.
14 Unlike Australia, a number of other countries from which horses were exported to Australia had had experience of EIV prior to August 2007.
15 Accordingly, despite the fact that pre-export quarantine was carried out in those countries before exporting the relevant horses to Australia, there was a risk that horses coming into the ECQS for post-entry animal quarantine could be infected with EIV and that the virus could escape from the ECQS into the naive Australian horse population.
16 During August 2007, six consignments of horses were due to arrive in Australia and were required to undergo post-entry animal quarantine at the ECQS.
17 Between about 17 July 2007 and 6 August 2007, four horses underwent pre-export quarantine on the Japanese island of Hokkaido, prior to being flown to Australia.
18 On about 8 August 2007, those four horses were flown from Japan to Australia and transported to the ECQS.
19 For the purposes of the proceeding, it was agreed amongst the parties that one or more of those four horses was either infected with EIV or was carrying the virus on its body. Further, it was also agreed that EIV was introduced into the ECQS by one or more of those four horses.
20 In the proceeding, the applicants alleged that EIV escaped from the ECQS and into the general Australian horse population by no later than 18 August 2007 by the clothing, body or equipment of a person, or other object carried by a person, who had had contact with EIV within the "equine enclosure" at the ECQS and who had not complied with specified biosecurity procedures.
21 The Commonwealth disputed that fundamental allegation and claimed that EIV had escaped from the ECQS via airborne spread into the general Australian horse population. If that contention were established at trial, the Commonwealth would not have been held liable in the proceeding.
22 The presence of EIV outside the ECQS was first detected on 24 August 2007.
23 As stipulated in the Commonwealth's pre-2007 policies for handling outbreaks of EIV, stringent movement controls on horses and horse products (quarantine and movement controls and international import suspensions) were immediately put in place. Despite these actions, the EIV quickly spread as described at [12] above.
24 Of the many horses outside the ECQS which contracted EIV, a number died. In addition, there were wide ranging and serious economic consequences for many persons and entities engaged in the horse breeding and racing industries, including the cancellation of racing events and serious disruption to the 2007 breeding season which was due to commence on 1 September 2007.
25 In the ASC, the group members were described as follows:
(a) Persons who suffered property damage in their capacity as owners (or lessees) of horses which suffered from EIV after the outbreak and who suffered ancillary loss in that capacity;
(b) Persons who suffered pure economic loss as a result of the movement controls that were implemented to control the outbreak of EIV. This group included the following categories of persons:
(i) Owners of Australian horses;
(ii) Owners of imported horses;
(iii) Agistment businesses;
(iv) Businesses using Australian horses;
(v) Businesses using foreign horses;
(vi) Horse racing clubs;
(vii) Equestrian clubs;
(viii) Equestrian centres (ie riding centres);
(ix) Australian horse transporters;
(x) International horse transporters;
(xi) Jockeys;
(xii) Farriers;
(xiii) Trainers;
(xiv) Horse breakers;
(xv) Bookmakers;
(xvi) Horse auctioneers;
(xvii) Bloodstock agents; and
(xviii) Racing photographers.
26 The class is a closed class, it being a pre-condition to membership of the class that group members must have entered into a litigation funding agreement with the relevant litigation funder, Argentum Centaur El Funding Private Limited (Argentum).
27 In the proceeding, the applicants alleged that the Commonwealth owed a direct duty of care to the applicants and group members to take reasonable care to prevent the escape of EIV from the ECQS as a consequence of the Commonwealth's capacity as lessee and occupier of the ECQS to control the premises constructed thereon and as a consequence of its capacity to impose such conditions as it thought fit on the entry of others onto those premises.
28 In the alternative, the applicants also alleged that the Commonwealth was vicariously liable for the negligence of a number of its officers and employees.
29 At par 32 of his affidavit affirmed on 23 August 2016 which was read in support of the settlement approval orders claimed by the parties, Mr Julian Schimmel, who was the lawyer at Maurice Blackburn Pty Ltd (Maurice Blackburn) charged with the carriage of the proceeding in the interests of the applicants, said:
The central issues arising in the proceeding are as follows:
(a) Whether the Commonwealth owed a duty of care to the Applicants and Group Members to take reasonable care to prevent the escape of EIV from ECQS?
(b) If so, did the Commonwealth breach that duty?
(c) If so, did that breach cause the harm suffered by the Applicants and the Group Members?
(d) If so, how is that harm to be quantified by way of damages?
(e) Can the Commonwealth avoid liability because the officers for whose breach(es) the Commonwealth is said to be vicariously liable are immune by virtue of section 82 of the Quarantine Act 1908 (Cth) (Quarantine Act) from any liability for such damages?
(f) Can the Commonwealth avoid liability because of the principles in sections 43, 43A and/or 44 of the Civil Liability Act 2002 (NSW) concerning the liability of public authorities?
(g) Does the principle in Little v The Commonwealth (1947) 75 CLR 94 at 114 prevent the Commonwealth from having any vicarious liability for breach(es) by its officers?
(h) Do the principles of proportionate liability set out in the Civil Liability Act 2002 (NSW) apply to limit the quantum of any liability the Commonwealth would otherwise have?

30 At pars 45-62 of his affidavit, Mr Schimmel discussed in more detail the issues which he had identified at par 32.
31 In the course of that brief discussion, Mr Schimmel identified a number of serious difficulties or obstacles standing in the way of the applicants. I need mention only three: The first concerns the question of whether either of the alleged duties of care was owed to the group members in the circumstances of the present case. The second concerns the factual question of precisely how the EIV escaped from the ECQS. The third concerns the question of causation.
32 It is sufficient for present purposes for me to simply note that the applicants' case was beset by a number of serious obstacles and that success would ultimately depend upon the applicants' being able to overcome all (not just some) of those obstacles.
