REASONS FOR JUDGMENT
1 On 9 June 2006, the Court heard two motions. The first filed was the applicant's motion, notice of which was dated 8 May 2006, seeking, amongst other things, leave to amend its application and statement of claim and an order for what was referred to as a split trial. The second was the respondents' motion, notice of which was dated 5 June 2006, seeking, amongst other things, orders that parts of the current statement of claim be struck out.
THE RESPONDENTS' STRIKE OUT MOTION
2 I turn first to the respondents' motion. In substance, the respondents (referred to hereafter as "Telstra") seek orders that what has been called the "no cap" representation claim be summarily dismissed pursuant to O 20 r 2 of the Federal Court Rules ("the Rules").
3 In paragraph 20 of the statement of claim, the applicant (referred to hereafter as "MWO") alleged that Telstra made a representation to the effect that, provided MWO achieved certain conditions, Telstra would not enforce a part of the 2003 agreement that required MWO to refund to Telstra any amount that it received from Telstra exceeding 18% of Net Billings (hereafter referred to as "the cap"). (At the hearing of this motion, the construction of the clause was not the subject of dispute.) By paragraph 24 of the statement of claim, MWO alleged that, relying on the truth of the representation, MWO:
(a) agreed to terminate the 2002 agreement;
(b) discontinued the 2002 proceeding (being a proceeding instituted by MWO against Telstra in the Supreme Court of Victoria)
(c) executed the 2003 agreement; and
(d) "otherwise acted to its detriment".
MWO claimed that, in seeking to enforce the cap, Telstra has engaged in conduct that was misleading and deceptive, or likely to mislead or deceive, in contravention of s 52 of the Trade Practices Act 1974 (Cth) ("TPA").
4 The loss or damage that MWO claimed to have suffered "by" this conduct was identified in paragraph 29 of the statement of claim to be the fact that MWO was subjected to Telstra's demands, in 2004 and 2005, to repay the sums that Telstra claimed constituted remuneration in excess of the "cap" and that MWO refunded these sums "involuntarily, under protest".
Submissions on the strike out application
5 Telstra submitted that the detriment asserted by MWO cannot amount to "damage" sufficient to found a cause of action pursuant to ss 82 or 87 of the TPA. That is, according to Telstra, the pleading failed to establish a causal connection between the alleged damage and the conduct of Telstra alleged in paragraph 20 of the statement of claim. In support of this submission, Telstra referred to numerous authorities, including Marks v GIO Australia Holdings Ltd (1998) 196 CLR 494 ("Marks") at 503-4, Wardley Australia Ltd v Western Australia (1992) 175 CR 514 ("Wardley") at 525, Gates v City Mutual Life Assurance Society Ltd (1986) 160 CLR 1 at 14; HTW Valuers (Central Queensland) Pty Ltd v Astonland Pty Ltd (2004) 217 CLR 640; Henville v Walker (2001) 206 CLR 459 at 501 [130], and I & L Securities Pty Ltd v HTW Valuers (Brisbane) Pty Ltd (2002) 210 CLR 109 at 121 [31]. Telstra submitted that MWO failed to allege the "better" position that it would have been in "but for" its reliance on the representation, or otherwise to seek to connect the damage alleged in paragraph 29 of its statement of claim to any such "better" position. Telstra submitted that the authorities establish that MWO had thus failed to meet a fundamental pleading requirement if it is to make out its cause of action under ss 52 and 82 or 87 of the TPA in respect of the no cap representation.
6 Further, Telstra submitted that the whole of MWO's evidence in chief, as now filed, failed to establish an arguable case that "but for" reliance on the no cap representation, MWO could and would have achieved an agreement on all fours with the 2003 agreement, but without the cap. Telstra submitted that, in the circumstances before the Court, there is no reasonable prospect of MWO establishing on the balance of probabilities that but for its reliance on the representation it would have achieved the 2003 agreement without the cap.
7 In written submissions, Telstra also challenged MWO's pleading of promissory estoppel. In paragraphs 34A to 34F of the statement of claim, MWO alleged promissory estoppel against Telstra. That is, MWO claimed that it would have acted to its detriment and suffered loss and damage if Telstra were allowed to rely on the capping. As the pleadings stood at the relevant time, MWO said that it would provide particulars at a later date of its detriment and of loss and damage. Telstra submitted that it was reasonable to anticipate that the only "detriment" would be that alleged in paragraph 29 of the statement of claim. MWO's proposed amendment to the statement of claim confirmed that this assumption was correct. Telstra submitted that, for the reasons already stated, entry into the 2003 agreement with the 18% cap did not of itself establish relevant detriment. That is, according to Telstra, the promissory estoppel claim was but another iteration of the no cap misrepresentation claim and could not succeed at trial.
8 MWO submitted that the impugned parts of its statement of claim were not so clearly untenable that they could not possibly succeed. MWO said that Telstra misrepresented its pleading and that "no aspect of [MWO's] case is that 'but for' the representation the 2002 Agreement would have continued". MWO affirmed that "[t]he status quo at the time of Telstra reneging on the representation not to enforce the cap, was the 2003 Agreement 'uncapped'. The loss to [MWO] flowing from the wrongful conduct was the consequence of the imposition of the cap".
9 In response to Telstra's strike out application, MWO relied chiefly on the High Court's decision in Murphy v Overton Investments Pty Ltd (2004) 216 CLR 388 ("Murphy").
10 In Murphy, the Court determined what, if any, relief under Pt VI of the TPA the appellants should have for a contravention of Pt V. They had been induced to enter into a lease of a unit in a retirement village. The lease provided that they should pay certain outgoings. The trial judge found that, in entering into the lease, they had relied on a misrepresentation that the figure for likely outgoings had been calculated taking into account all relevant costs. The figure had not been so calculated and turned out to be much higher than that nominated when the lessors entered the lease. The trial judge found that, had the lessors known the true position, they would not have entered into the lease. The High Court held that the appellants' undertaking of the obligation to pay the increased outgoings figure gave rise to the possibility that they could demonstrate that they had suffered loss and damage: Murphy at 415-6 [74].
11 MWO submitted that, in Murphy, the High Court did not require the appellants to establish what agreement they would have entered into had the misrepresentation not been made. MWO noted that the Court found that the Full Federal Court had erred in applying the "but for" test for which Telstra contended. In written and oral submissions, MWO put their response to Telstra in this way:
"Thus in Murphy:
(a) Overton represented that the outgoings would be calculated on a certain basis;
(b) The Murphys' relied upon it and were induced to enter into the lease;
(c) No loss was suffered at the time of entering into the lease;
(d) The loss arose when Overton charged outgoings on a higher basis than that represented;
(e) The Murphys were entitled to recover the difference between the outgoings as represented and those charged.
By analogy here:
(a) Telstra represented that if [MWO] entered into the 2003 Agreement, it would not enforce the cap …;
(b) Telstra's representation was relied upon by [MWO] and induced [MWO] to do the things alleged in sub paragraphs 24(a) to 24(e);
(c) Telstra's representation did not result in any loss to [MWO] at the time of entering into the 2003 Agreement;
(d) the loss to [MWO] arose when Telstra … sought, contrary to the Representation, to enforce the cap;
(e) once Telstra sought to enforce the cap, [MWO] suffered damage, namely the difference between the remuneration capped and uncapped.
(f) Accordingly, [MWO is] entitled to recover this difference as pleaded."
12 MWO contended that the loss that it alleged was the amount that it was required to pay Telstra "involuntarily and under protest", namely, $21,283,642.61 and $12,640,377.17. This was, so MWO said, "precisely that type" of loss that "was endorsed by the High Court in Murphy" and it could not, therefore, be said that its claims were hopeless, bound to fail or without any prospects of success.
13 MWO also contended that Telstra misrepresented its estoppel claim, which was in fact as follows:
"(a) by making the [no cap representation] and Warranty, Telstra induced [MWO] to assume or expect that Telstra would not enforce the [cap];
(b) [MWO] relied upon the [no cap representation] and Warranty and did each of the acts and matters alleged;
(c) at the time of making the [no cap representation] and Warranty, Telstra intended that [MWO] would act in reliance on [no cap representation] and Warranty;
(d) [MWO] will have acted to its detriment and suffered loss and damage if the assumption or expectation induced in [MWO] by Telstra is not fulfilled;
(e) it is now unconscionable for Telstra to resile from the [no cap representation] and Warranty and the assumption or expectation induced thereby;
(f) Telstra by reason of the[se] matters ... is now estopped from denying the full force and effect of the [no cap representation] and Warranty and seeking to rely upon the [cap]."
14 MWO contended that the causal connection between the no cap representation and warranty and the detriment was constituted by its entry into the 2003 agreement and doing the other acts as alleged in reliance on the representation and warranty. The detriment was the non-fulfilment of the no cap representation and warranty. MWO relied on Walton Stores (Interstate) Limited v Maher (1988) 164 CLR 387 at 428-9, Commonwealth v Verwayen (1990) 170 CLR 394 at 442-6 and Giumelli v Giumelli (1998) 196 CLR 101 at 112-4, as well as the reasons for judgment of Gyles J in the Full Court of this Court in Murphy (which MWO said met with the High Court's approval) in support of the proposition that there was no deficiency in its pleading to support its estoppel claim. MWO also referred to its proposed amendment to paragraph 34D, which, so it said, "makes plain that [it] relies upon the particulars subjoined to paragraph 24 as to the acts which it did to its detriment and relies upon the particulars subjoined to paragraph 29 as to the loss and damage occasioned by Telstra's failure to fulfil the assumption or expectation induced in [it] by making the [no cap representation] and Warranty". MWO submitted that this claim was plainly arguable.
Consideration of the strike out application
15 Order 20 rule 2 of the Rules provides as follows:
"(1) Where in any proceeding it appears to the Court that in relation to the proceeding generally or in relation to any claim for relief in the proceeding -
(a) no reasonable cause of action is disclosed;
(b) ...
(c) …
the Court may order that the proceeding be stayed or dismissed generally or in relation to any claim for relief in the proceeding.
(2) The Court may receive evidence on the hearing of an application for an order under subrule (1)."
16 Prior to the enactment of s 31A of the Federal Court of Australia Act 1976 (Cth), which came into force on 1 December 2005, the standard to be satisfied before any order would be made under this provision was settled law. The Court would exercise its powers under this rule with great care and only make an order against an applicant in a very clear case that disclosed no tenable claim: see, e.g., Dey v Victorian Railways Commissioners (1949) 78 CLR 62 at 91; General Steel Industries Inc v Commissioner for Railways (NSW) (1964) 112 CLR 125 at 129-130; Fancourt v Mercantile Credits Ltd (1983) 154 CLR 87 ("Fancourt") at 99; and Webster v Lampard (1993) 177 CLR 598. Whether or not the Court is satisfied that that there is no real question to be tried (see Fancourt at 99) will depend entirely on the circumstances of the case.
17 As MWO ultimately conceded, the new s 31A does not apply to this proceeding, because this proceeding was instituted before the commencement of the operation of the provision: see Item 44 of Part 2 of Schedule 1 of the Migration Litigation Reform Act 2005 (Cth). Accordingly, the Court should apply the authorities to which I have just referred.
18 Although the pleadings have been amended from time to time, the nature of the claims made are, for present purposes, sufficiently described in the reasons for judgment of Crennan J in Mobileworld Operating Pty Ltd v Telstra Corporation Ltd [2005] FCA 292 ("Mobileworld (1)") at [3] to [4]. Further, as reference to her Honour's decision shows, this is not the first time that this aspect of MWO's pleading has been challenged: see Mobileworld (1) at [25]-[30].
19 The authorities establish that the relief that ss 82 or 87 of the TPA may afford is not confined to the remedies in tort, contract or equity: see, eg, Marks at 503-4. Further, the causative element in a cause of action under ss 52 and 82 (or 87) of the TPA is to be "understood as taking up the common law practical or common-sense concept of causation": Wardley at 525. Causation is a question of fact. As the Court said in Murphy, at 403, the difference between price and value is not the only kind of damage for which compensation can be given in such an action as this. It is necessary to identify the detriment which is said to be the loss or damage which has occurred or, when considering the application of s 87, has occurred or is likely to occur: see Murphy at 408. In Wardley, as the Murphy Court noted, "the mere entry into obligations which might, but need not, have had detrimental consequences in the future was held not to have occasioned loss or damage to the party making the contract": see Murphy at 408. The Court went on to hold, at 409-10, that in the Murphys' case:
"[T]he finding that [they] had been induced to enter the lease by a statement of estimated outgoings that was misleading, because it did not take account of all amounts that could properly be charged as outgoings, meant that [they] undertook an obligation which may, but need not, have proved to be larger or more costly than they had been led to believe. There may be cases in which a person misled in this way suffers loss upon entering the agreement. …But that was not this case. …
What [they] did not know was that the estimate of outgoings they were given did not provide for all the outgoings that were then being incurred. Here, therefore, [they] suffered no loss as a result of undertaking the obligations they did unless and until the contingency which the misrepresentation hid … was first realised. … It was only from the time when it in fact decided to depart from the 1992 position and charge for the wider categories that the adverse risk eventuated. When it did, but only then, [the Murphys] suffered loss and damage."
20 MWO specifically relied on this passage and a further passage, at 413, that read:
"[The Murphys] had been induced by the respondent's conduct to undertake an obligation which may, but need not, have been more onerous than the respondent's representation led them to believe. When the respondent started to charge all the outgoings it was entitled to charge, [they] suffered a loss. The amount of that loss was not to be determined … only by comparing the financial position of the [Murphys] according to whether they entered this lease or took some other accommodation. … The [Murphys] suffered loss because the continuing financial obligations they undertook when they took the lease proved to be larger than they had been led to believe. The question then became: how much larger was that burden?"
21 MWO's pleading attempted to trace the reasoning of the Murphy Court. MWO contended that it did not incur loss when it entered the 2003 agreement. Rather, it incurred loss when Telstra departed from the no cap representation and sought to recover remuneration over the cap. MWO's case is that it suffered loss only when Telstra sought to enforce the cap for which the 2003 agreement provided, notwithstanding that Telstra had represented to MWO that it would not do so. Accordingly, so MWO said, this loss was to be measured as the recoupment amounts that Telstra had claimed.
22 Whatever the difficulties this analysis may ultimately present for MWO in terms of proving causation and detriment, it would not be a proper exercise of discretion to strike out this cause of action. In light of ss 52 and 82 (or 87), as explained further in Murphy, MWO's claim is arguable and not clearly so untenable that it must fail.
23 For similar reasons, I would not strike out the pleadings in so far as they raise a claim of estoppel against Telstra. Examination of the statement of claim shows that it sufficiently pleads the requisite elements of an estoppel as disclosed in the authorities mentioned in [14] above. These authorities establish that a pre-contractual representation can form the basis for an estoppel. In the case as pleaded, the unconscionability, if any, is said to lie in the fact that Telstra unilaterally departed from the assumption it had created by the no cap representation after the 2003 agreement was made. Having regard to the reasons for judgment of Gyles J in Murphy v Overton Investments Pty Ltd (2001) 112 FCR 183 at 225-228, it would not be a proper exercise of discretion to strike out this part of the pleading as clearly untenable. Further, the decision of the High Court in Murphy does not support such a course.
24 For the reasons stated, I would dismiss Telstra's motion, notice of which was given on 5 June 2006. No party suggested that there should be any departure from the ordinary provision as to the costs of an unsuccessful motion.
THE APPLICANT'S MOTION FOR A SPLIT TRIAL AND OTHER THINGS
Submissions on the split trial application
25 MWO applied to have the quantification of any loss or damage suffered by MWO as alleged under paragraph 41 of the Second Further Amended Statement of Claim ("SFASC") determined subsequently and separately to all other matters in the proceeding. MWO also sought to be relieved of the obligation to file, prior to trial, evidence going to the quantification of this loss.
26 In support of its application for a split trial, MWO relied on affidavits of Nicholas John Andersen sworn on 9 May 2006, 24 May 2006 and 8 June 2006, together with exhibits. MWO also relied on three affidavits of Timothy John Rumbold sworn on 28 April 2006, 8 May 2006 and 8 June 2006, and an affidavit of Dennis Vincent McCluskey sworn on 23 May 2006, together with its exhibits.
27 MWO submitted that, to calculate its loss under paragraph 41, it would need to calculate the trailing commissions and other remuneration due to it under its 2003 agreement with Telstra. Put simply, trailing commissions are commissions paid in relation to Telstra accounts for mobile phones sold in MWO stores. To calculate such commissions, it is said to be necessary to know what is referred to as the Service in Operation (or "SIO") base. Essentially, the SIO base is constituted by those services within Telstra's database attributable to MWO.
28 In detailed written and oral submissions, MWO claimed that its evidence established that Telstra's business and accounting records are inadequate in so far as they relate to calculating its SIO base and trailing commissions. In this connection, MWO referred to Mr Rumbold's affidavit of 28 April 2006 and 8 May 2006, as well as Mr Andersen's affidavit of 9 May 2006 and 24 May 2006. Further, MWO submitted that it would be an enormously complex task to unravel the flaws in Telstra's record keeping so as properly to calculate the moneys owed to it. MWO further submitted that it would "not be able to put on all relevant evidence … prior to the commencement of the Trial fixed for 2 October 2006 because of the magnitude of the task and the evidence that would be required". There was, so it said, the potential for an enormous waste of time and money in the event that it failed to establish liability against Telstra. It further submitted that "quantification of loss and damage under paragraph 41 may ultimately be found … to be best performed by a Court appointed expert".
29 MWO referred to an audit conducted by William Buck, Chartered Accountants ("William Buck"). MWO claimed that this audit identified significant deficiencies in Telstra's business systems and records. According to MWO, the William Buck audit took two years to complete and cost over two million dollars even though it was narrower in scope than an audit required to determine the actual remuneration payable by Telstra to MWO. The applicant argued that it would be an even greater task to determine its damages under paragraph 41 of the SFASC. MWO submitted that Telstra's discovered documents also disclosed that there were significant deficiencies in Telstra's databases and business and accounting systems.
30 MWO submitted a report by Dennis McCluskey of William Buck. MWO's solicitors had asked Mr McCluskey to inform them as to how long he believed it would take his firm to conduct a remuneration audit that calculated the sum owed by Telstra to MWO. Mr McCluskey replied that such an audit would take between 5 and 18 months depending on the level of assurance required.
31 MWO claimed that its evidence established that the preparation of evidence of the quantification of any loss and damage suffered by it under paragraph 41 of the SFASC would require many months of work by experienced professionals and would likely cost more than one million dollars. In MWO's submission, the complexity of calculating this loss and damage meant that it was not practical to have that issue determined at the same time as other issues. Although MWO argued that the Court should defer determination of the loss or damage suffered under paragraph 41 of the SFASC, it submitted that "having been satisfied that some loss and damage has been occasioned, the principles upon which [its] claim for loss and damage under paragraph 41 should be determined."
32 In response to the affidavit of Lisa Jane Parry sworn 6 June 2006 and filed by Telstra, MWO submitted that Ms Parry's affidavit referred only to peripheral issues concerning loss and damage such as the administration fee under the 2003 agreement and advertising costs. MWO argued that the calculation of trailing commissions was the key issue and noted that Ms Parry's affidavit was silent on that topic.
33 For reasons set out in detail in its written submissions and concisely in its oral submissions, Telstra opposed MWO's application for a "split trial". In summary, Telstra said the proposed order offered no utility in terms of the efficient and timely disposition of the proceeding and a better solution might be found after Telstra had filed and served its evidence.
34 Telstra submitted that MWO was obliged to put on evidence as to quantification or explain what information it lacked that prevented it from so doing. It said that the possible difficulty of the task did not relieve MWO of this obligation. Telstra characterised McClusky's statements as "vague and unparticularised", noting that he did "not propose or identify a methodology and merely assumes a need for investigation of all Connections and Trailing Commissions".
35 Telstra contended that, in the circumstances of the case, it would not be possible for the parties or the Court to know what evidence goes "solely to the quantification" of loss, as opposed to going to liability, breach, or the existence of any loss. It relied on the affidavit of Ms Parry, and referred to the affidavit of Mr Rumbold and the William Buck reports as illustrative of this. Telstra pointed out that it was far from clear whether the proposed orders contemplated that the Court consider all, or only some, of these reports and whether Telstra could file answering material.
36 Telstra maintained that some quantification was relevant to determining issues of liability (see further amended statement of claim, paragraphs 59 to 72N, 38 and 40A, 37(a) and 35 to 41). As to these claims, Telstra stated:
"On the invalid notification claim as alleged by MWO, Telstra is entitled to adduce evidence going to any alleged inaccuracy in the overpayment amounts notified for 2003 and 2004. It would not be just and convenient for the orders sought to be made in circumstances where such quantification evidence could be subjected to an application for exclusion on the grounds of relevance. Likewise, for MWO's claims that Telstra has breached an implied obligation to keep an accurate and reliable account keeping system (denied). As part of its evidence in defence of this claim, Telstra is entitled to adduce evidence dealing with a quantitative assessment of the level of dollar values of disputes/inaccuracy which MWO must establish to prove on the balance of probabilities that there has been a breach of the alleged implied term (itself denied).
MWO's various breach of contract claims (both actual and implied terms), and invalid notification claims, raise squarely issues of quantification. Telstra is entitled to adduce relevant quantification evidence which rebuts these allegations, albeit that it is not necessarily the case that such evidence must establish amounts to the last dollar."
37 As Telstra observed, the affidavits sworn by Mr Andersen on 9 May and 24 May 2006 indicate that, at trial, MWO will seek to rely on Telstra's own documents to support an inference that Telstra's dealer payment recording systems failed to record accurately the "SIO's" in respect of which MWO obtained a trailing commission entitlement. Telstra denied that the documents would support such an inference and Telstra submitted that it was entitled to adduce evidence that any impact was minor or, even possibly, cash flow positive for MWO. On one view, so Telstra said, such evidence might be said to go solely to quantification.
38 Further, as Telstra said, Ms Parry's affidavit tended to throw doubt on whether MWO has received less than its claimed entitlements in respect of administration fees and program incentives. If the proposed orders were sought, then MWO would not be required to put on any evidence concerning the individual, or total, amount of such fees and incentive payments it claims should have been and were not paid. Moreover, according to Ms Parry, Telstra cannot investigate MWO's claims for co-operative advertising until MWO provides further details of such claims.
39 Telstra also stated that it was proposing to cross-examine MWO's deponents on that part of its proposed evidence that included quantification (as, for example, the proposed evidence of Mr Rumbold).
40 Telstra pointed out that there will be a need to make findings of fact (some of which may involve issues of credit) on liability and that the same or some of the same witnesses will be relevant at the "quantification" stage. It submitted that there would be no savings in time and expense in adopting the "split trial" approach of MWO.
41 Telstra further submitted that it was not for the Court to initiate an investigation at large to see whether there were any amounts "unpaid" to MWO. The Court was obliged to act only on the evidence adduced before it. It was, so Telstra said, incumbent on MWO to satisfy the Court on the balance of probabilities that it was contractually entitled to an amount for trailing commissions in excess of what it had been paid. It did not have to calculate its alleged loss down to the exact cent but it did have to indicate what it estimated its loss to be and the basis for that estimate.
Consideration of MWO's application for a split trial
42 Order 29 rule 2 of the Rules confers power on the Court to make orders for "… the decision of any question separately from any other question, whether before, at or after any trial or further trial in the proceeding". The principles that govern the circumstances in which an order of the kind presently sought may be made were set out in Reading Australia Pty Ltd v Australian Mutual Provident Society [1999] FCA 718 ("Reading") at [7] and [8] per Branson J. French J reiterated these principles in Olbers Co Ltd v Commonwealth (No 3) [2003] FCA 651 ("Olbers") at [7]. In Reading at [8], Branson J summarised the relevant principles as follows:
"The principles that govern the circumstances in which an order will be made under O 29 r 2 are relatively well established. They may be summarised as follows:
(a) the term "question" in O 29 r 1 includes any question or issue of fact or law in a proceeding. … ;
(b) a question can be the subject of an order for a separate decision under O 29 r 2 even though a decision on such a question will not determine any of the parties' rights …;
(c) however, the judicial determination of a question under O 29 r 2 must involve a conclusive or final decision based on concrete and established or agreed facts for the purpose of quelling a controversy between the parties …;
(d) where the preliminary question is one of mixed fact and law, it is necessary that the question can be precisely formulated and that all of the facts that are on any fairly arguable view relevant to the determination of the question are ascertainable either as facts assumed to be correct for the purposes of the preliminary determination, or as agreed facts or as facts to be judicially determined …;
(e) care must be taken in utilising the procedure provided for in O 29 r 1 to avoid the determination of issues not "ripe" for separate and preliminary determination. …;
(f) factors which tend to support the making of an order under O 29 r 2 include that the separate determination of the question may -
(i) contribute to the saving of time and cost by substantially narrowing the issues for trial, or even lead to disposal of the action; or
