PART 1: INTRODUCTION (and an Executive Summary)
Executive Summary

  1. This proceeding concerns claims by the plaintiff, Santos Limited as principal (Santos) against the first defendant, Fluor Australia Pty Ltd as contractor, and against Fluor Corporation as guarantor (together, Fluor).[1] This court referred all of the issues arising from the pleadings to a panel of three referees.

    [1]           For convenience, when referring to the first defendant/contractor, I will use the expression ‘Fluor’.

  2. There are two applications before the court. One is an application by Fluor to set aside the reference which was ultimately heard by the referees over 62 sitting days up to August 2022.[2] In March 2023, the referees provided a draft report to the parties. A month later Fluor brought the first application, an application to set aside the reference (the SA application). The SA application was made on the basis that the reference process was affected by apparent bias, a failure to comply with the referral order, an excess of jurisdiction, a lack of procedural fairness, and because the reference process had become a miscarriage of justice.

    [2]           There were two further sitting days in April and July 2023.

  3. In July 2023 the court commenced hearing the SA application. It was allocated 10 sitting days from 17 July 2023. In the meantime, on the eve of the hearing of that application, the referees converted their draft report into a final report. That led to Santos bringing the second application, a cross-application (the 505 application), for the court to adopt the referees’ report pursuant to rule 505D of the Uniform Civil Procedure Rules 1999.

  4. Both applications were ultimately heard over a total of 43 sitting days in July 2023 and then in February and March 2024. No evidence was heard during the course of the hearing of the two applications, but the parties referred to and relied on the written and oral evidence and submissions received by the referees during their 62 sitting days.

The SA Application

  1. First, the referees’ draft report referred to and relied on both the pleadings and the very extensive written and oral submissions of the parties. The referees addressed the essential arguments of each party on the real issues in dispute as they appeared from the submissions. It was reasonable for them to do so.

  2. Second, the referees decided the issues in accordance with the pleadings. The examples submitted by Fluor do not demonstrate that the referees strayed beyond the pleadings and thereby failed to comply with the referral order or exceeded their jurisdiction.

  3. Third, apprehended bias will arise where a fair-minded lay observer might reasonably apprehend that the decision-maker might not bring an impartial mind to the decision. Such an observer would not conclude apprehended bias here because no issue was taken as to the referees conduct of the reference. The criticisms made by the referees of Fluor, and Fluor’s case and its witnesses were the end-product of their decision-making process and would not have caused the fair-minded lay observer to think that the referees had prejudged the case, or that the referees had brought minds that were other than impartial to the decision-making process.

  4. Fourth, there is no evidence or basis for saying that the referees failed to consider Fluor’s submissions. The referees were not obliged to address, in their reasons, every single argument put by the parties. What was necessary was a basic explanation of the fundamental reasons which led the referees to their conclusions. The referees’ reasons satisfied that requirement.

  5. Fifth, contrary to Fluor’s submissions, there is no separate common law remedy that enables the court to set aside a referral order on the basis of a miscarriage of justice. Instead, the court possesses a broad discretion under rule 502 of the Uniform Civil Procedure Rules 1999 (Qld) (UCPR) to set aside or vary a referral order or to accept, vary or reject all or part of the referees’ report under rule 505D. Those discretions are, of course, required to be exercised bearing in mind the interests of justice. In any event, the interests of justice are part and parcel of both applications.

  6. Consequently, the SA application will be dismissed.

The 505 (Cross) Application – Legal Issues

  1. The 505 application required the court to exercise the discretion to accept, vary or reject all or part of the referees’ report by applying the principles in Chocolate Factory Apartments Pty Ltd v Westpoint Finance Pty Ltd.[3] That required the discretion to be exercised in this way:

    [3] [2005] NSWSC 784.

(a) the court should re-consider and determine legal issues afresh; but
(b) the court should refrain from reconsidering disputed questions of fact unless the referee’s report reveals some error of principle, an absence or excess of jurisdiction, patent misapprehension of the evidence or perversity or manifest unreasonableness in fact-finding.
  1. Thus, the court should not interfere where there was factual material sufficient to entitle the referees to reach the conclusions they did.

  2. The cross-application for the court to adopt the report will be allowed, with some modifications that are identified in these reasons.

  3. There were four significant legal issues, all involving the interpretation of the contract between the parties. The first of those legal issues was whether the Fluor was correct that clause 29.4(b) had the effect that:

(a) Santos was not entitled to issue a ‘negative’ payment certificate requiring Fluor to make a payment in the absence of proof of an error by Santos; and
(b) Santos was precluded from issuing such a certificate if it made the payment voluntarily or made the payment with knowledge that the payment was not payable under the contract.
  1. The referees found against Fluor on the first of those arguments and in favour of Fluor on the second of those arguments. However, the referees found as a fact that Santos did not actually know that it was paying amounts part of which were Excluded Costs under the contract, though it became suspicious over time that it was being overcharged.

  2. In my view, the referees’ interpretation of clause 29.4 of the contract was correct as to the first argument but incorrect as to the second. The words of clause 29.4, and the context, do not make Santos’ knowledge in making the payments relevant at all.

  3. Second, Fluor relied upon clause 37.9 of the contract as an answer to five of Santos’ claims that it paid Excluded Costs because Fluor had supplied Free Issue Materials that did not comply with the specifications for those items. Fluor argued that the referees did not address Fluor’s argument that clause 37.9 operated to deem, as Actual Costs, the costs claimed by reason of the supply of defective materials. Fluor is correct that the referees did not substantively deal with this legal issue. However, the issue was not adequately pleaded or proved by Fluor. And, even if it had been adequately pleaded and proved, on the proper interpretation of clause 37.9, the defence did not properly extend to the costs of consequent delay and/or disruption.

  4. Third, Fluor raised a limitation of liability provision in the clause 54.2 of the contract as a defence. In my view the referees were correct to adopt a narrow interpretation of clause 54.2. That clause does not limit the alleged liability of Fluor to repay what was said to be Excluded Costs. In short, the limitation did not comprehend the price paid or to be paid under the contract.

  5. Fourth, Santos sought to recover from Fluor its Mechanical Completion Delay claim. That was a claim to recover from Fluor sums paid for time related indirect costs paid in the period between the date for Mechanical Completion and the date when Mechanical Completion was achieved. In the absence of a delay notice, those costs were, in effect, barred by clause 23 of the contract. The referees found that the claims were valid and followed the Court of Appeal’s 2021 decision in Santos Limited v Fluor Australia Pty Ltd.[4] This court is bound to follow that decision.

    [4] [2021] QCA 204.

The 505 (Cross) Application – Factual Issues

  1. The referees rejected Santos’ largest claim, the CDJV Conversion claim. However, a number of other claims made by Santos succeeded and the referees’ recommended declarations to the effect that Santos was entitled to claim those amounts back from Fluor. Parts 12 to 23 of these reasons involve a consideration of a large number of submissions made by Fluor as to why the referees were wrong to find in favour of Santos.

  2. Some of those issues involve arguments about the pleadings, and about legal issues and the application of legal principle, and about the factual findings made by the referees. It is impractical to try to summarise those issues here.

  3. However, it is clear that the referees have grappled with and decided the real issues. The referees’ report does not reveal any error of principle, or an absence or excess of jurisdiction, or a patent misapprehension of the evidence, or perversity or manifest unreasonableness in fact finding.

  4. To use the words of the authorities,[5] having closely scrutinised the referee’s report, the court is left with a comfortable feeling of satisfaction that the factual issues have been properly explored and considered by the referees and the court declines to interfere in the various findings made.

    [5]            See Part 3.

The Result

  1. The referees’ report should be adopted by the court, with any necessary modifications in light of these reasons. There are three variations or qualifications to the referees’ report that need to be resolved.

  2. The referees concluded that the clause 29.4 payment certificate on which Santos relied was ineffective because it claimed substantially more than the amount that was properly due. I do not agree. In my view judgment should be entered, with (simple) interest, but subject to the three variations/qualifications.

Background

  1. Applegarth J described the parties in this proceeding as being engaged in litigation on a monumental scale arising from the construction of the upstream component of a major coal-seam gas project between 2011 and 2014.[6]

    [6]            This was the description given to the dispute by Applegarth J in April 2023 in Santos Limited v Fluor Australia Pty Ltd [2023] QSC 77 at [1].

  2. The Gladstone Liquified Natural Gas Project (the GLNG Project) is a coal seam gas to liquified natural gas project in central and southern Queensland. The GLNG Project involves the extraction of coal seam gas in fields in central southern Queensland, including at Fairview and Roma, and, after initial processing, the transportation of that gas by a long-distance gas pipeline to Curtis Island at Gladstone. There the gas is liquified into liquified natural gas and loaded onto ships.

  3. The proponents of the GLNG Project were a joint venture of Santos (30 per cent), Petronas (27.5 per cent), Total (27.5 per cent) and Kogas (15 per cent). The components of the GLNG Project at and near the fields are referred to as being “upstream”. The gas transmission pipeline and the facilities on Curtis Island are referred to as being “downstream”. The GLNG Project required:

(a)  the development of many hundreds of wells at the upstream fields;
(b)  the development of upstream surface facilities, including:

(i)       wellpads;

(ii)      gas and water gathering networks;

(iii)     nodal and hub compressor stations;

(iv)     water treatment facilities;

(v)      at Roma, underground gas storage and associated injection and withdrawal facilities;

(c)

construction of the downstream gas transmission pipeline to transport gas to Curtis Island;

(d)

construction of the downstream liquified natural gas plant at Curtis Island together with associated infrastructure such as port facilities.

  1. This proceeding relates to an upstream component of the overall GLNG Project. That component is referred to as the project.

  2. The parties entered into a contract in about 13 January 2011. That contract was subsequently amended on or about 19 August 2011.[7] By the contract, as amended, Fluor agreed to engineer, procure and construct the following facilities:

    [7]            The amended contract altered the method for payment of Fluor. The method of payment is discussed later.

(a)  three gas compression plant facilities (each a Hub) and associated utilities and infrastructure, at the following three locations in the Fairview and Roma Fields:

(i)       north-east of Injune (Hub 5);

(ii)      east of Injune (Hub 4); and

(iii)     east north-east of Roma (Hub 2);

(b) modifications to pre-existing gas compression facilities;
(c) wellpads at various locations throughout the Fairview and Roma Fields, and associated infrastructure and facilities, including water and gas flow lines to transport CSG and associated water from the wellpads to the Hubs; and
(d) roads, construction lay-down areas, high voltage transmissions lines from the Hubs to the wellpads and other facilities.[8]

[8]            The summary of the Project in these paragraphs is taken from Fluor’s SA submissions at [31]-[37]. The description is not in dispute.

  1. Santos’ claims against Fluor can be categorised into these three categories:

(a)

an entitlement to recover alleged overpayments of the contract price totalling over $1.4 billion (the overpayment claims);

(b)

damages in the amount of approximately $140 million, for breach of a collateral contract or for misleading or deceptive conduct in contravention of the Australian Consumer Law, on the basis that the labour rates charged by the first defendant on the project allegedly impermissibly included an allowance for profit (the profit- in-rates claims);

(c)

liquidated damages of $15 million, for the alleged failure of the first defendant to achieve “Mechanical Completion” of certain “Parts” of the works by the contractually required dates (the liquidated damages claim).[9]

[9] Fluor summarised the claims in Fluor’s SA submissions at [82].

The Reference

  1. On 15 February 2021, and subsequently, Bradley J made orders that referred all questions arising on the pleadings to three referees.[10] Those referees were the Hon. Robert McDougall KC, the Hon. Richard Chesterman KC and Mr Michael Rudge SC. Hearings were held before the referees for a total of 62 sitting days between November 2021 and August 2022.[11] There were two further sitting days before the referees in April and July 2023.

    [10]           The referral was pursuant to Uniform Civil Procedure Rules 1999, r 501.

    [11] This summary of the proceedings before the referees is deliberately brief. Fluor have summarised the proceedings from the time of the referees’ appointment at Fluor’s SA submissions, [56]-[74].

  2. It is fair to say that the referees were disgruntled about the volume of the evidence put before them. Their final report explains that there were some 171 lay witness statements, 76 expert reports, eight joint expert reports, 6,115 pages of oral evidence and many, many thousands of documentary exhibits – not all of them short.

  3. The referees were also displeased with the volume of submissions. As they explained in the final report, “the parties inflicted prodigious quantities of submissions on us”. Fluor itself provided to the referees over 4,600 pages of written opening, closing and reply submissions, and more than two days of oral closing submissions.[12] Santos’ submissions were similar in scale. Santos estimates that the referees were given nearly 10,000 pages of submissions by the parties.[13]

    [12] Santos’ SA submissions at [15].

    [13] Santos’ SA submissions at [60].

  4. As will be seen, the fact that the parties, to use the language of the referees, inflicted voluminous pleadings, evidence and submissions on the referees had consequences in the way they approached their task.

  5. On 7 March 2023 the referees provided a draft report to the parties.

  6. Fluor was unhappy with the draft report and so, by an application filed on 4 April 2023, Fluor sought the following orders:

(a) the referral order of Bradley J made on 15 February 2021 be set aside;[14]
(b) the various orders for the conduct of the reference also be set aside;[15]

(c)

directions be made for the hearing of an application by Fluor for summary judgment in respect of some of the issues[16] and for directions in relation to the disposition of the balance of the issues;

(d)

alternatively, directions as to the determination of preliminary issues and directions as to the disposition of the balance of the issues.

[14] UCPR r 502 permits a court to set aside or vary a referral order made under UCPR r 501. The test, of course, is whether it is in the interests of justice to do so.

[15]           The amended application lists orders made on 15 February 2021, 24 February 2021, 27 May 2021, 19 October 2021 and 2 November 2021.

[16]           The application describes these as clauses 29.4 and 41.2 issues (as defined in [4] of the application) and the claims made by the Plaintiff in the following paragraphs of the Fifteenth Amended Statement of Claim: [246]-[289.1] (the profit in rates claim).

  1. In broad terms, Fluor sought those orders because it contends that: the reference process is affected by apparent bias; the referees have failed to comply with the referral order and have acted outside their jurisdiction; the reference process is affected by a lack of procedural fairness; and the reference process has become a miscarriage of justice. Fluor’s application was set down for a hearing and was heard over 10 days commencing on 17 July 2023. No decision was made on that application, because, with the agreement of the parties, it was necessary for the court to also consider a cross-application by Santos (discussed below).

  2. In the meantime, the referees converted their draft report to a final report which was delivered to the parties on 14 July 2023 – on the eve of the hearing of Fluor’s application. Fluor’s application was heard over ten sitting days from 17 July 2023.

  3. Santos was content with the both the draft and final referees’ report. And so, Santos made a cross-application that the final referees’ report should be accepted by the court pursuant to r 505D of the UCPR. That cross-application was heard over a further 33 sitting days from 12 February 2024.

  4. There are many issues that overlap. For example, some of the facts that Fluor relies on as evidence of apprehended bias are also relied on as a reason why the court should not accept the referees’ report.

  5. For convenience, I will refer to Fluor’s application as the SA application,[17] and Santos’ cross-application as the 505 application or the 505 cross-application.[18] Similar abbreviations will apply to the parties’ submissions.

    [17]           The parties often referred to Fluor’s application as the Set Aside Application. I have simply abbreviated.

    [18]           The parties often referred to the cross-application as the 505D Application or the Adoption Application. Again, I have abbreviated.

[46] Santos’ supplementary submissions at [5].

[47]             The expression ‘that obstacle’ no doubt refers to the prior discussion on the inconsistency with the

written terms which concludes (at paragraph 180): “It is scarcely credible that parties in the positions

of Fluor and Santos – a global Tier 1 contractor and an energy giant respectively - each possessed of

vast commercial experience and having access to the best legal advice, would negotiate a contract in
the terms and detail that they did, whilst knowing that each intended (and knew that the other
intended), that essential terms of the contract would operate other than as they were written.”

[60]             As is the case elsewhere, Fluor uses the expressions ‘fail to consider’ and ‘fail to address’

interchangeably. Here, the likelihood is that Fluor’s complaint is that the referees failed to address in

the sense of refer to the evidence. That seems clear from paragraph [3416(a)] of Fluor’s 505

submissions.
