The Montara Class Action Decision and Implications for Corporate Accountability for Australian Companies

A ground-breaking judgment of the Australian Federal Court regarding the Montara oil spill in the Timor Sea in 2009, Sanda v PTTEP Australasia (Ashmore Cartier) Pty Ltd (No 7) (Sanda (No 7)),1 is one of the few Australian class actions to proceed to a favourable judgment for the claimants. It is also the first judgment against an Australian company for cross-border pollution loss suffered by foreign claimants.


I. INTRODUCTION
A ground-breaking judgment of the Australian Federal Court regarding the Montara oil spill in the Timor Sea in 2009, Sanda v PTTEP Australasia (Ashmore Cartier) Pty Ltd (No 7) (Sanda (No 7)), 1 is one of the few Australian class actions to proceed to a favourable judgment for the claimants. It is also the first judgment against an Australian company for cross-border pollution loss suffered by foreign claimants.
The Federal Court upheld the claim of an Indonesian seaweed farmer, Daniel Sanda, on his own behalf and on behalf of a class of 15,500 Indonesian seaweed farmers, after oil and gas company PTTEP Australasia (Ashmore Cartier) Pty Ltd's (PTTEPAA) negligent operation of the Montara well led to the worst oil spill in Australia's offshore petroleum industry history, and the spread of oil into coastal waters in neighbouring Indonesia.
The decision is a timely reminder that Australian courts providing access to justice according to law, regardless of the size, influence or nationality of the parties before it, are one of the most powerful and honourable institutions Australia possesses. 2 It further underscores that class actions can facilitate access to justice to large groups of vulnerable people who have been substantially affected by environmental misadventure and catastrophe.
Section II of this piece provides an analysis of the case, covering both procedural and substantive aspects of the decision. Section III then outlines the authors' views of the implications of the decision for the corporate accountability of Australian oil and gas companies.

II. CASE ANALYSIS
On 21 August 2009, there was a major blow-out at the Montara wellhead platform, which caused oil and gas to flow unabated into the Timor Sea for over 10 weeks. On 3 August 2016, the class action was commenced in the Federal Court against the operator of the well, PTTEPAA, a subsidiary of the national Thai oil and gas giant, PTT Exploration and Production Public Company Limited (PTTEP). The class action alleged that oil from the spill reached the coastal areas in and around 81 villages in the Rote/Kupang region of Indonesia's Nusa Tenggara Timur province, killing seaweed being cultivated by 15,500 seaweed farmers and causing production to dramatically fall for some years. See Figure 1 for a map of the region.
Mr Sanda's claim was that PTTEPAA owed him and the group members a duty of care when operating and suspending the operation of the Montara well, and that PTTEPAA breached that duty of care by negligently enabling the oil spill that killed the seaweed, causing financial loss. PTTEPAA denied that it owed, or breached, a duty of care to the seaweed farmers. It claimed that Montara oil did not reach the Rote/Kupang region, or if it had, that it did not damage seaweed because it was harmless by the time it reached the area. It was not in dispute that PTTEPAA's 'gross incompetence' in suspending the H1 Well caused the blow-out. Nor was it in dispute that there had been a widespread die-off of seaweed in the Rote/Kupang region around the time of the spill.
A central challenge for Mr Sanda's case was the lack of contemporaneous scientific monitoring or appraisal of the transboundary spread and environmental impact of the oil pollution in Indonesia. Australia's response effort and a later Commission of Inquiry focused on Australian territory, the cause of the spill and future prevention rather than any transboundary environmental impact. 3 The Commission report, however, noted that there was evidence that oil entered both Indonesian and Timor Leste's waters 'to a significant degree'. 4 With the paucity of contemporaneous scientific studies, evidence of the oil reaching the coastal areas in Indonesia was instead provided by a number of Indonesian seaweed farmers who gave first-hand eyewitness accounts of the arrival of oil and the subsequent destruction of their seaweed. Key to the case was whether the Indonesian witnesses would be believed and their evidence given weight.
From the outset, the class action has been funded by Harbour Litigation Funding. 5 Harbour funded the detailed investigation and development of the claim, paid the legal costs of Mr Sanda's legal team throughout the course of the case and provided security for costs of the action. Harbour's involvement assisted considerably in addressing what otherwise would have been the power and resource imbalance between the Indonesian seaweed farmers and the well-resourced PTTEPAA.

A. Procedural Aspects
The hearing was conducted in two broad phases: (i) the taking of lay evidence from seaweed farmers in the Rote/Kupang region and other lay observers, and (ii) the taking of extensive expert evidence from experts across a broad range of disciplines.
PTTEPAA required a significant number of the Indonesian seaweed farmers to attend court in Australia to give evidence of their observations of oil, having rejected a proposal that the Court take evidence of witnesses in Indonesia. A practical challenge was to then get the farmers from their remote island communities to Sydney to give evidence. Only a small number of the seaweed farmers had ever been out of their local region, and none spoke English. Farmers from approximately 30 of the 81 villages attended the Federal Court to give evidence. They were selected on the basis that the 30 locations were sufficiently representative of the broader coastal areas which were the subject of the claim, to enable conclusions to be drawn about where the oil arrived in the region. 6 Passports and visas were obtained, consular assistance organised, flights and accommodation arranged, courtapproved interpreters appointed, and bi-lingual translators and 'minders' engaged to facilitate communications. This was coordinated by Mr Sanda's legal team.
PTTEPAA called no lay witnesses, despite it having been closely involved in the oil surveillance and recovery operations during the blow-out (including engaging and coordinating aircraft and vessel operators). Instead, it relied heavily on the expert evidence of its largely United Sates-based expert witnesses, and most especially, their oil spill modelling expert. The expert had prepared a detailed after-the-event trajectory analysis which purported to show that oil from the blow-out could not have reached the Rote/Kupang region. Notably, the expert was not asked to consider the seaweed farmers' evidence of what they had seen.
The seaweed farmers were fortunate in having the trial heard in the second half of 2019, at a time of open borders and frequent international air travel. They were also fortunate in the way the trial was managed by the Court and the open mindedness with which they, and Mr Sanda's other lay witnesses, were received.
An integral feature of how the Federal Court manages its cases is the individual docket system. This allocates a case to the docket of a particular judge at the time of filing (in this instance Justice David Yates), with the intention that it remain with the same judge for case management and disposition at trial. 7 The over-arching purpose of civil practice and procedure and case management within the individual docket system is to facilitate the just resolution of disputes according to law as quickly, inexpensively and efficiently as possible. 8 This system allowed Justice Yates to flexibly apply the most appropriate and efficient mechanisms for case management to the circumstances of the case. As managed by Justice Yates, the system proved well suited to dealing with issues that arose during the proceeding. For example, Justice Yates directed that six different Court-facilitated concurrent expert conclaves be held, each of which produced joint reports. The participating experts were then required to give their oral evidence concurrently, with up to five experts participating at once. This saved a considerable amount of Court time and identified the key issues in dispute sooner than would otherwise have occurred.
Mr Sanda and the group members were entitled to bring the claim in Australia despite their being foreign national claimants. The jurisdictional 'anchor' of the Federal Court's authority at law to decide personal actions is based on its capacity to exercise power to compel the defending party to submit to orders made, rather than the claimants' connection with the jurisdiction. 9 PTTEPAA's connection to the jurisdiction was clear: 6 Mr Sanda read 43 affidavits, of whom 19 deponents were cross-examined at trial. In addition, Mr Sanda called 11 expert witnesses, while nine were called by PTTEPAA.  it is an Australian company and the registered holder of the relevant petroleum retention lease, and the Montara oil field was located in Australian territorial waters. Moreover, PTTEPAA admitted that the operation of the Montara oil field was an inherently dangerous and extremely hazardous activity that carried the risk of harm and that it was subject to the legal obligations imposed on it by Section 569 of the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (Commonwealth). 10 Consequently, PTTEPAA did not argue that the Indonesian seaweed farmers were unable to bring the claims due to their being foreign nationals.

B. Substantive Aspects
In reaching his findings, Justice Yates took as his starting point the large body of evidence of the seaweed farmers of the presence of (what they described as) oil, on the beaches and coastal waters of the Rote/Kupang region in late 2009 and the impact on their seaweed crops. His Honour found those observations provided a coherent and convincing body of evidence containing recurring observations of features and effects which were consistent with the material being weathered Montara oil. 11 PTTEPAA criticised the seaweed farmers' evidence on the basis that many of the farmers had communications over the years (including some with lawyers) which must have 'infected' their memories by 'impressions formed in the telling and re-telling of events', 12 such that their evidence was 'contaminated to a very large extent' 13 and could not be relied upon. Justice Yates rejected that submission, finding that: 'I am left in no doubt that, at the time, all witnesses (seaweed farmers, village heads, and other lay witnesses) witnessed a single, strikingly unusual, and unique event in the Rote/Kupang region, which coincided with the quick and dramatic loss of local seaweed crops.' 14 Justice Yates stated his impression was that all the lay witnesses spoke frankly on the topic of what they observed, although he noted, some at times had difficulty in following the line of questioning put to them. He suspected that, in part, might have been due to cultural differences and the court setting in which they gave evidence, being far removed from their normal, day-to-day experiences. 15 Furthermore, Justice Yates found the lay evidence informed a number of the key expert issues. For example, he found that it was a mistake for PTTEPAA to treat its after-theevent oil spill trajectory model's predictions as a true representation of what happens in the real world, and that such predictions were to take 'no precedence over the other evidence including, in particular, the actual observations of witnesses in that area at the time.' 16 In addition, he determined that toxicological evidence needed to be considered in 10 The obligations being, inter alia, to carry out all petroleum exploration and recovery operations in a proper and workmanlike manner and in accordance with good oilfield practice; and control the flow, and prevent the waste or escape in the petroleum production licence area, of petroleum or water. light of what the seaweed farmers observed occurring including, for example, the oil adhering to their seaweed and the ropes on which the seaweed was grown. 17 C. The Decision: 'The Obvious Cannot be Ignored' After assessing all the evidence, Justice Yates found that 'taking all the evidence into account, I am satisfied, on the balance of probabilities, that Montara oil from the H1 Well blowout, in various weathered states, reached the coastal areas of Rote/ Kupang'. 18 In relation to the critical causation question of whether Montara oil caused, or materially contributed to, the quick and dramatic loss of local seaweed crops, Justice Yates concluded that it had: 'Given the descriptions of the seaweed farmers, there can be no doubt that crop death coincided with the arrival of the oil … The obvious cannot be ignored.' 19 In so doing, Justice Yates rejected the range of alternative explanations for the seaweed die-off put forward by PTTEPAA, finding there was no other plausible explanation for that widespread loss. 20 Justice Yates was satisfied that PTTEPAA owed Mr Sanda and the seaweed farmers the duty of care pleaded, and the risk of a blow-out of the H1 Well was very high. He concluded: I am in no doubt that it was reasonably foreseeable to a person in the respondent's position, at the relevant time, that a failure by the respondent to properly suspend the H1 Well could result in an uncontrolled release of hydrocarbons that could cause loss or damage in the Rote/Kupang region, including to those whose businesses or enterprises involved the commercial exploitation of the marine ecosystem affected by that release. 21 Given that the foreseeability of that risk of harm arising was established, Justice Yates was satisfied that PTTEPAA breached its duty of care to Mr Sanda and the seaweed farmers, concluding that no 'other consideration has been raised which militates against a finding of breach'. 22 Therefore, the question of whether Mr Sanda's seaweed crops were damaged by Montara oil could 'be answered readily' in the affirmative. Mr Sanda's losses, although difficult to assess given that he had no documentation recording his seaweed production before and after his crop loss, could, Justice Yates concluded, be calculated, awarding Mr Sanda's losses for the period 2009-2014 of approximately AUD22,000 (not including interest and costs). 23

D. What Next?
The class action procedure is staged: this decision is the initial trial of the issues common to Mr Sanda's claim and the 15,500 group members. A second stage will now take place whereby the other seaweed farmers' claims for losses will be assessed, informed by the Court's decision made in relation to Mr Sanda's losses.
In practice, group members' claimed losses are often dealt with by a settlement whereby individual compensation entitlements are assessed according to a settlement scheme. To date, PTTEPAA and its USD22 billion parent, PTTEP, 24 have not expressed an interest in offering any money to settle the farmers' claims. That may change after final orders are made, at the time of writing expected in September 2021, whereupon the time for any appeal will start running. 25

III. IMPLICATIONS OF THE DECISION
The Australian Federal Court decision in Sanda (No. 7) is important for five key reasons. First, the decision demonstrates that foreign nationals, even an economically and legally disenfranchised group of seaweed farmers, can obtain justice in Australia that they would otherwise have been unable to obtain. An editorial in the Jakarta Post heralded the decision as a rare, even unheard of, win for ordinary Indonesian people in legal proceedings. 26 At a practical level, the decision shows that existing procedures provide the Federal Court with the flexible tools needed to provide access to justice to people from quite different cultural settings. It is a testament to Australia's well-functioning justice system that Indonesian seaweed farmers can attend court in a foreign land and give firsthand eyewitness evidence through interpreters, which evidence, after being fully tested, is given precedence over evidence from leading international experts (the latter admittedly hypothetical in nature).
Second, the decision in Sanda (No. 7) demonstrates that class actions in Australia can provide access to justice for those affected by environmental harms, serving as a form of private regulation of polluters and offering a form of private regulation against environmental wrongdoing. It shows that class actions can work even in the environmental area. It will encourage the investigation and commencement of more environmental class actions and assist in overcoming the historic wariness of plaintiff lawyers and litigation funders to pursue such cases given they often involve issues of considerable factual and scientific complexity.
Third, the decision puts Australian companies, especially in Australia's large offshore oil and gas industry, on notice that they may be held accountable for the damage caused by 24 PTTEP, 'Annual Report 2020', https://www.pttep.com/en/Investorrelations/Regulatorfilings/Annualfiling.aspx (accessed 1 June 2021). 25 In addition, the parties to the class action are awaiting a supplemental judgement from the Court on whether the oil reached all or only some of the coastal areas in and around the 81 villages; this judgment is currently expected in September 2021. pollution events by private action (including class action) even if the claimants are foreign nationals. Indeed, class actions in relation to pollution caused by Australian companies' activities or those of their subsidiaries in foreign territories are now being conducted and could, as a result of this decision, also become more of a regular occurrence in Australian courts.
Fourth, the decision in Sanda (No. 7) highlights the inherent risks of exploitation of natural resources by Australian companies operating both domestically and internationally at a time of heightened risk and global concern. Environmentally sensitive projects must be managed with great care if disastrous consequences for the environment and local communities are to be avoided.
The 'ever-present risk' 27 of pollution from an offshore accident is presently even more extremedue to the massive decommissioning risks and liabilities in the offshore gas and oil industry 28 and concerns that Australia could struggle to respond to another major oil spill, such as the current disaster off the Sri Lankan coast, due in part to industry changes brought on by the COVID-19 pandemic restrictions. 29 For example, the Northern Endeavour, an insolvent floating production facility with structural issues due to advanced corrosion 30 with an even closer proximity to Australia's Timor Sea neighbours than the Montara oil field (see map in Fig. 1), is a pressing and ongoing transboundary environmental danger. Yet again, poor industry behaviour and historically lax regulation has been exposed. 31 Fifth, the decision in Sanda (No. 7) is a clarion call for action on an international convention to regulate liability and compensation in respect of transboundary loss and damage as a consequence of offshore oil and gas activities, as has long been exhorted by another Judge of the Federal Court of Australia, Justice Rares. Such a convention would provide a just and effective alternative to hard-fought, time-consuming and costly litigation in the courts. Even with effective court systems, the costs and delays are too great. In the words of Justice Rares, an international convention 'will help to ensure that all persons … who are adversely affected by pollution damage from blowouts or oil spills from fixed platforms, can claim and be paid fair and adequate compensation in a timely fashion.' 32
