- This is the single judgment of the court.
- Before the Court is an appeal against the judgment of the Competition Appeal Tribunal ("CAT") of 19th October 2021 by which the CAT granted two applications by a representative acting for a proposed class of claimants ("the class representative") for collective proceedings orders ("CPOs"). In that judgment the CAT dismissed applications made by the defendants to strike out the claim or part of it and/or for reverse summary judgment.
- The claim is brought pursuant to section 18 Competition Act 1998 ("CA 1998") which is known as the "Chapter II prohibition". Section 18(2)(a) prohibits unfair purchase or selling prices or other unfair trading conditions:
- The applicant in both cases is Mr Justin Gutmann. The claim in both cases is that the defendants, who are train operating companies ("TOCs"), unlawfully abused a dominant position by failing to make so-called "Boundary Fares" sufficiently available to consumers holding valid "Travelcards" issued by Transport for London ("TfL").
- Travelcards are TfL zonal tickets permitting unlimited travel on London's public transport network. This includes not only TfL's own services but, in addition, those of National Rail within their zone of validity excluding certain lines such as Heathrow Express. Travelcards can be issued for variable time periods and for a range of zonal combinations. There are in total nine TfL zones. However, zones 1 – 6 are the main zones and cover approximately 99% of all valid Travelcards.
- A Boundary Fare is a form of add-on or supplementary ticket for use in conjunction with the Travelcard for travel to/from the outer boundary covered by the Travelcard from/to the destination. If a consumer wishes to travel from central London to a destination on (say) the south coast, that consumer will travel from central London (A) to the boundary station of the Travelcard (B) and then onward to the destination (C). In this A-B-C journey the purchase by the consumer of the Travelcard should entitle the consumer to treat the A-B leg as having already been paid for with the consequence that the consumer should be charged only for the B-C leg. The nub of the claim is that the defendant TOCs failed to make Boundary Fares available either at all or in a way that was sufficiently available. The practical effect was that for a high percentage of journeys consumers with Travelcards paid the full fare and not the appropriate Boundary Fare. Put another way TOCs charged twice for the A-B leg of the journey.
- The claims relate solely to journeys out of, but not into, London. It was explained to the CAT that the claim had been framed in this manner for the sake of simplicity. The class is estimated to comprise about three million individuals who have suffered individual losses of about £33 - £55. The average claim per journey is about £5. The total claim against the defendants combined is about £93 million.
- The claim concerns Boundary Fares on two rail franchises: The South-Western franchise and the South-Eastern franchise. In both cases the claim covers the period from the 1st October 2015 to the date of final judgment or earlier settlement of the claims (in the case of the South Western franchise) or at 2am on the 17th October 2021 (in the case of the South Eastern franchise). The CAT treated the claims as substantially identical and with the consent of all parties, directed that the two applications be heard together and that evidence in the one would stand as evidence in the other so far as relevant.
- In relation to the South-Western franchise, during the relevant period there were two respondent TOCs to the first application: First MTR South Western Trains Limited ("First MTR") which held the franchise from and including the 20th August 2017; and, Stagecoach South Western Trains Limited ("Stagecoach") which held the franchise from 4th February 1996 until 20th August 2017. The South-Eastern franchise was held from the commencement of the relevant period until the 17th October 2021 by London South Eastern Railway Limited ("LSER").
- The definition of the class, as certified by the CAT, was in broad terms and encompassed "all" persons who held a Travelcard and who paid a full fare:
- The CAT ordered certification upon an opt-out basis. It directed that every person falling within the description of the class domiciled in the United Kingdom on the 19th October 2021 should be included in the collective proceedings. Any person falling within the class could opt out of the proceedings according to a process set out in the order.
- As explained in greater detail below, the defendants unsuccessfully sought to strike out the applications and/or obtain reverse summary judgment. The CAT refused permission to appeal.
- The proceedings concern Travelcards available for combinations within zones 1 – 6:
- The arrangements for the provision and honouring of Travelcards are governed by a Travelcard Agreement signed on the 15th October 1995 (the "Travelcard Agreement"). This is (for practical purposes) between TfL and the TOCs. This is a complex arrangement which has been subject to a series of subsequent amendments, modifications and restatements. The full terms of these arrangements were placed before the court subject to a confidentiality ring. It is unnecessary to delve into the detail. It suffices to record that in recital (B) to the Travelcard Agreement it is recorded that upon implementation of the restructuring of the passenger rail industry as contemplated by the Railways Act 1993:
- The arrangements include complex terms governing the apportionment of total revenue generated by the sale of Travelcards as between the parties to the agreement. As part of the methodology the parties, collectively, instituted a "Travelcards Survey Working Group" which was tasked with the creation of a survey enabling passenger kilometres travelled on each mode by Travelcard holders to be estimated and, thereby, to permit relevant apportionment factors to be derived. We were informed that the methodology presently applied to determine apportionment no longer includes evidence generated by such surveys.
- All the defendants either sell or have sold Boundary Fares for journeys originating in each TfL zone to destinations upon their networks. They are sold as single or return, peak or off-peak fares. They are not routinely available for certain discounted tickets of which the most significant are Advance Fares. Each of the defendant TOCs makes tickets available from a variety of outlets which include station ticket counters, ticket vending machines ("TVMs") operated by the defendants, TVMs operated by third parties, telephone call centres, online sales, TfL-controlled outlets and third-party vendors holding a licence permitting them to sell such tickets.
- The claims concern journeys out of London originating in a TfL travel zone on the networks of the defendants and are referred to as "in-scope journeys". Paragraph [20] of the judgment sets out tables recording the class representative's estimate of the proportion of in-scope journeys with Boundary Fares on the South Western and South Eastern franchises and the inference which could be drawn viz., that only a very small percentage of in-scope journeys are charged at the Boundary Fare rate[1]:
- In paragraph [26] of the judgment the CAT referred to evidence of the limited extent to which Boundary Fares were, in fact, available from different types of outlet:
- In a draft re-amended collective proceedings claim form, the class representative encapsulated the alleged abuse in the following terms:
- The following is also averred:
- The system of collective redress under the CA 1998 has been described in the Supreme Court judgments in Mastercard Inc v Merricks [2020] UKSC 51 ("Merricks") and Lloyd v Google LLC [2021] UKSC 50 ("Lloyd"). The system, as interpreted by those judgments, was considered in a judgment of this Court in BT Group plc v Justin Le Patourel [2022] EWCA Civ 593 at paragraphs [24] - [44] ("Le Patourel"). There is no need to repeat here what has been thoroughly rehearsed in these earlier cases. It suffices to highlight those features of the regime which are of relevance to the issues in these appeals.
- Under the CA 1998 and implementing regulations for a claim to be certified the CAT must assess whether the issues raised are the "same, similar or related". The shorthand for issues that meet this test is that they are "common" (Le Patourel (ibid) paragraphs [31] and [32]). The CAT has to determine whether the claim is "suitable" for certification as a collective action. The test of "suitability" is multifactorial: Le Patourel (ibid) paragraphs [81] – [83].
- In determining whether a claim is suitable the CAT does not consider the merits of the claim. However, putative defendants have the right to seek to have the claim struck out as unarguable or otherwise seek reverse summary judgment upon it. To this extent, when an application for summary dismissal is made, the CAT will, to the arguability threshold, consider the merits.
- To enable the CAT to form a judgment on commonality and suitability the class representative is required to put forward a "methodology" setting out how the issues that they have identified will be determined or answered at trial. In practice the methodology is prepared by an expert economist instructed by the proposed class representative. The methodology advanced will be counterfactual and therefore hypothetical in nature. It posits how the market would operate absent the alleged unlawful conduct and provides a benchmark against which to measure a defendant's actual conduct. It constitutes a critical document that the CAT will examine when determining commonality and suitability. The test to be applied to a proposed methodology to determine whether it is up to standard was articulated by the Supreme Court of Canada in Pro-Sys Consultants Ltd v Microsoft Corp [2013] SCC 57 ("Microsoft") and was endorsed by the Supreme Court in this jurisdiction in Merricks. We address the test in paragraphs [45], [46] and [52] – [63] below.
- The CAT also has a power to order that the claim proceed upon an aggregate basis. Section 47C(2) CA 1998 empowers the CAT to make an award of damages without reference to the position of individuals:
- The architecture of the UK regime has been partially modelled upon Canadian collective redress regimes which exist for all types of case, not just competition law. In Canada there are a variety of different provincial systems. Case law on these has, to date, been valuable in guiding the Courts in settling the broad principles which should apply. The relevance of this jurisprudence is considered at paragraphs [40] – [42] below.
- In the present case the CAT: dismissed the defendants' applications for strike out and/or reverse summary judgment; held that the methodology advanced by the class representative met the Microsoft test; directed that the case proceed under section 47C(2) as a claim for aggregate damages which was to include liability issues; and, certified the claim as "suitable" upon an opt-out basis thereby holding that the issues were sufficiently "common". The appeals raise a variety of issues in relation to these conclusions. We summarise the issues arising as follows:
- We deal with each of these issues in turn.
- The first issue is about how liability, as opposed to quantum, must be established in collective actions. This is a point of law. By "liability" we refer to the requirement to prove (a) causation and (b) the existence of some loss flowing from a breach. If section 47C(2) does not apply, liability issues must always be proven by reference to the position of individual claimants. This would have profound consequences for whether a claim was "suitable" for collective proceedings. The appellants argue that the CAT erred in holding that section 47C(2) covered liability and that as a result of this error it erred in concluding that the proceedings were suitable for certification. The CAT recorded this argument (judgment paragraph [77]) but held that section 47C(2) did embrace liability issues and that the question had already been decided by the Supreme Court in Merricks.
- The appellants argue now that the CAT erred in treating Merricks as having decided the point. The majority did not address the issue and the minority (which did) was obiter and unconvincing. Further, the analysis addressed a different factual matrix to that arising in the present case. In Merricks there was no possibility of class members suffering no loss, so the issue of aggregate liability did not arise. This contrasts with the present case where the defendants have identified numerous categories of consumer in the certified class who will have suffered no loss by not having been offered or obtained Boundary Fares and in respect of whom there can therefore be no liability. Merricks is distinguishable. Further, the observations of the Supreme Court in Lloyd were obiter and carry no persuasive weight. Applying normal principles of construction, section 47C(2) cannot lead to the conclusion that it extends to liability. Finally, Canadian authority, based upon legislation which does not include an aggregate damages system with class-wide liability, works well so that a construction of section 47C(2) which confines its scope to quantum is unproblematic. We turn now to address these arguments.
- Pass-on is relevant to liability. If a claimant has passed on an unlawful charge to its customers, it might have suffered no loss even if it was the direct victim of a cartel or other unlawful conduct. The Court of Appeal in Merricks [2019] EWCA Civ 674 held that the issue of pass-on was capable of leading to the conclusion that a claimant had suffered no loss but was nonetheless an issue that could be aggregated under section 47C(2) and was capable of being a common issue. The Court held:
- There was no appeal against this finding to the Supreme Court. Nonetheless, the Court approved of the conclusion of the Court of Appeal (ibid., paragraphs [64(a)] and [66] per Lord Briggs for the majority and paragraph [170] per Lord Leggatt and Lord Sales for the minority). This was noted and relied upon by the CAT in the present case (paragraph [113]) which held that properly analysed there was no inconsistency between the majority and minority in Merricks. The CAT also pointed out, by reference to an analysis in academic literature[2], that this conclusion differed from the conclusion of the Supreme Court of Canada in its jurisprudence under legislation of British Columbia which, as the CAT put it, reflected a "different statutory approach" (paragraph [113]).
- In Lloyd the entire court expressly held that the aggregated damages provisions in section 47C(2) could apply to liability as well as to quantum: see paragraph [31].
- These authorities were referred to with approval by this Court in Le Patourel (ibid at paragraph [32]), albeit in the context of the dichotomy between opt-out and opt-in claims.
- There is therefore a substantial body of case law treating section 47C(2) as applying to liability as well as to quantum. We do not accept that these authorities lack binding force. In Merricks it is true that the majority did not in terms explicitly apply section 47C(2) to liability but they nonetheless endorsed the judgment of the Court of Appeal which did adopt that position; and the minority was explicit. In Lloyd a unanimous court endorsed the conclusion that section 47C(2) applied to liability. That conclusion is in the part of the judgment where the court was considering alternative collective regimes to CPR 19.6 and is part of the overall logic of the judgment which was that where Parliament had intended to create collective regimes it had done so expressly. It can be inferred that the Court concluded that this was a reason not to endow the limited language in CPR 19.6 with a generous breadth. It is in our judgment an arid exercise to determine formulaically whether the Court's broad analysis of section 47C(2) formed part of the ratio. It is enough that it formed a part of the reasoning which led the court to its conclusion on CPR 19.6 and it is in any event, a unanimously expressed conclusion. We do not see any basis upon which we should decline to follow Lloyd.
- The appellants next argued that on the facts of Merricks the entire class was in an identical situation. All consumers using a card to make a purchase from a retailer paying an interchange fee had, to some degree, suffered loss. There were no scenarios where a no-loss situation could be identified. The observations of the Court of Appeal and Supreme Court had to be seen in this light and were accordingly distinguishable from the present case where there were many categories of consumer who had suffered no loss. Mr Moser QC disagreed referring to the treatment of pass-on in Merricks which was, he submitted, an illustration of possible no-loss claimants in a proposed class, and, the endorsement of the Supreme Court of the proposition that section 47C(2) could nonetheless apply (see paragraphs [31] and [32] above). Further, during the first instance proceedings in that case (when the facts were being determined) card issuers, in particular Mastercard, had tendered evidence highlighting differences between the various categories of cardholder and positing that there were no-loss categories and that this was relevant to their argument that the issues were not "common". The question of no-loss was accordingly a live issue which explained both paragraphs [45] and [47] of the Court of Appeal judgment and the analysis of the Supreme Court. We agree with Mr Moser QC. Supposed factual differences between Merricks and the present case are not a realistic way of distinguishing the judgment of the Supreme Court.
- The appellants further argued that section 47C(2) does not in its language refer to liability but only to damages. Read naturally the provision is limited to the size of an award of damages made in favour of an individual against whom a breach of duty had been established and who, by definition, had already been found (causally) to have suffered "some" (more than nominal or de minimis) loss from that breach. There was, it followed, no system of aggregation which could apply to the logically anterior liability issues of causation and loss.
- We disagree. It is common ground that quantum should be calculated so that an award of damages does not overcompensate. Section 47C(2) does not rewrite the constituents of the tort to remove liability issues; it merely permits those ingredients to be established deploying different - top down - evidence. In determining quantum, the CAT therefore necessarily ensures that it excludes from the calculation those who fail at the liability stage and the methodology must, at some point, include a device for winnowing out no-loss members of the class. When this methodology is applied it necessarily traverses the boundary between recoverability and non-recoverability. These are two sides of the same coin. We therefore have difficulty in understanding how an aggregate quantum exercise does not involve the CAT simultaneously determining liability for the simple reason that in fixing the outer-parameters of quantum it is also drawing the line between liability and non-liability. The language of section 47C(2) is consistent with this. It creates a power for the CAT in determining what is "recoverable" to apply an aggregate approach. The converse of recoverable is irrecoverable; the exercise of determining aggregate recoverability necessarily entails excluding categories of consumer who should recover nothing.
- In addition, section 47C(2) must be construed purposively. This includes: ensuring that the provision is "effective"; ensuring that it facilitates but does not hinder the enforcement of rights; and, enabling the collective regime to operate as a device which creates ex ante incentives for undertakings to comply with the law (see Le Patourel (ibid) paragraphs [25] – [30]). In NTN Corporation and others v Stellantis NV and others [2022] EWCA Civ 16 at paragraph [29] ("NTN"), the Court of Appeal, citing earlier Supreme Court and other judgments, described the principle of effectiveness: "… procedural and evidential rules must not make it practically impossible or excessively difficult to vindicate … justiciable rights". The appellants' construction of section 47C(2) does just that. If the appellants are correct, then the position of every individual in the class must be considered. Mr Moser QC did a quick calculation upon the basis that the claim of each individual was assessed by the CAT for a mere five minutes. He calculated that upon this basis the trial would last decades, which, as he put it, might pose a case management challenge for the Tribunal[3]. It is a defining feature of opt-out litigation that the class representative does not have to engage with individual class members until the distribution stage so that it would be inconsistent for the CAT, and inconsistent with the raison d'être of the collective action regime, to order opt-out certification but then require the class representative to be forced to call each member of the class to establish liability; thereby restoring opt-in by the back door.
- Finally, the appellants argued by reference to decisions of the Canadian courts which, it is said, are very important in shaping domestic law. They evidenced a robust and effective system of collective action operating without any form of mechanism for class-wide liability in the award of aggregate damages. This should lead this Court to adopt a limited construction of section 47C(2) confident that it would not undermine or emasculate the collective regime. We do not accept this argument. Unlike in Canada our domestic law does have an aggregate damages regime and it is the duty of this court to construe it in accordance with its purpose. Whether the Canadian system works well absent an equivalent is not a metric capable of sensible measurement and is not a proper approach to interpretation. How is this court to know whether the Canadian system is truly a success or not? In this regard Mr Moser QC drew our attention to academic literature on the Canadian regime which suggested that the absence of such a system for aggregation led to collective proceedings tending to fizzle out after common issues judgments with the parties diverting into ADR or mediation in order to find their own, non-judicial, aggregated ways of determining and distributing damages. In other words, because the legislation did not provide for aggregation the market was forced to find its own solution[4].
- In the course of the appeal, we were regaled with many Canadian and US authorities. It was said that the CAT erred in not following these cases. However, they pointed in all sorts of directions reflecting different governing laws and judicial practices and they revealed enduring differences between, for instance, judges in different circuits of the US. Standing back the value to date of Canadian authorities has been to assist in understanding the broad scope and architecture of the new domestic regime, introduced in 2015. They were useful in enabling the Supreme Court in Merricks to clarify some of the central guiding principles. In the present case the CAT helpfully summarised the main principles it considered could be drawn from the Canadian authorities which had both similarities but also important differences when compared with the domestic regime:
- Mr Moser QC expressed agreement with this summary. Neither of the appellants sought to pick holes in it. For our part we consider that it is a fair and accurate summary of the Canadian jurisprudence as it has continuing relevance to domestic law. It might, as case law evolves, not turn out to be exhaustive, but it is a very valuable starting point. At the more micro-level how different courts apply their discretion on an array of very particular certification issues under differing regimes to different facts is interesting and may have some modest illustrative value, but not much more than that.
- We treat the judgments in Merricks and Lloyd as dispositive and to be followed. In any event, in our judgment when interpreted purposively section 47C(2) is sufficiently broad to encompass liability and this conclusion is needed to ensure that the system of collective redress is workable. We reject this ground of appeal.
- This ground arises if the appellants are wrong in their submissions on Issue I and aggregation of liability is allowed under section 47C(2). The appellants then contend that the CAT erred in accepting that the methodology advanced by the class representative satisfied the Microsoft test. The methodology acts as a broad blueprint identifying the issues for trial and how they are to be resolved and provides important material from which the CAT can determine whether the issues are "common" and "suitable" for certification. It will therefore be relevant to a range of issues including breach of duty, causation, proof of loss and quantum.
- The claim in Microsoft was that Microsoft had overcharged electronics manufacturers for Intel-compatible PC operating systems and software purchased from retailers by class members. The Court held that the law permitted claims by indirect purchasers. In relation to certification the Court held that the standard of proof was the "some basis in fact" test set out in earlier case law (Hollick v Toronto (City), 2001 SCC 68). As to this Microsoft argued that the differences between the proposed class members were too great to satisfy the common issues requirement. The claim was based upon multiple separate instances of wrongdoing over a period of 24 years relating to 19 different products involving various co-conspirators and countless different contractual relationships. Further, the alleged overcharge had been passed on to the class members through the chain of distribution making it "… unfeasible to prove loss to each of the class members for the purposes of establishing common issues." The Supreme Court of Canada disagreed. Even a significant level of difference among the class members did not preclude a finding of commonality (applying Western Canadian Shopping Centres Inc v Dutton, 2001 SCC 46 ("Dutton")). If material differences did emerge during the proceedings the Court could deal with them at the time they arose (Dutton paragraph [54]).
- In relation to whether damages could be addressed as a common issue the Court considered that this depended upon the state of the expert evidence and the methodology proposed by the class. The articulation of the test to be applied by Rothstein J in Microsoft at paragraph [118] was adopted in Merricks in this jurisdiction. He said:
- The appellants highlight two aspects of the methodology advanced by the class representative's expert, Mr Holt, for particular criticism and argue that the CAT erred in law in accepting the methodology. The two areas of criticisms can be summarised as follows.
- First, they contend that the CAT was wrong to accept that the class could meet the Microsoft test by reference to a survey that the class intended to carry out in the future but had not, as of certification, conducted and/or that the description of the survey that was to be performed was so vague and imprecise that even if the CAT was entitled to defer it until later, it was still wrong to do so upon so insubstantial and flimsy a basis ("the survey issue"). Secondly, they contend that the CAT erred in coming to the conclusion that the class could take as a starting point an unproven and illogical assumption that no consumer would, rationally, wish to pay more for travel than they absolutely had to, and that it was therefore appropriate to certify a methodology which assumed but did not prove that all consumers in the class had suffered loss. This assumption was simplistic and unsustainable given that the defendant TOCs had adduced evidence before the CAT that there were many categories of case where Travelcard holders would not wish to obtain the lowest Boundary Fare or where Boundary Fares were simply irrelevant ("the assumption issue").
- In relation to both arguments the appellants contend that the paucity of detail in the methodology advanced by the class representative's expert failed to meet the Microsoft test. It was lacking in multiple respects: it was based upon speculation and unwarranted assumptions; it was based upon research and investigations which had yet to be carried out; it was incomplete in important respects in that it failed to grapple with issues such as the categorisation of no-loss claimants; it improperly reversed the burden of proof; and it created a risk that an award of damages would overcompensate the class and unfairly penalise the defendants.
- Mr Moser QC argued that the appellants' arguments came nowhere close to establishing that the approach of the CAT fell outside of its generous and broad margin of judgment or discretion. In its judgment the CAT summarised the step-by-step approach taken by Mr Holt, the expert instructed by the class representative. It expressed its own views upon the adequacy of each step. It evaluated whether the steps enabled the CAT at trial to adjudicate upon the issues arising. It addressed whether it could make adjustments later on during the course of the litigation to take account of variables and uncertainties and it addressed areas of the methodology which had yet, at the certification stage, to be undertaken and satisfied itself that they could be undertaken. The CAT questioned the class representative's expert from the witness box. The TOCs were entitled to pose questions but chose not to. When the judgment was fairly analysed there was no identifiable error of law which could be pointed to.
- These competing arguments raise an important issue as to the level of granularity and detail the CAT is required to demand of the methodology advanced by class representatives for the purpose of certification and compliance with the Microsoft test.
- We start with some observations on the Microsoft test based upon the facts of the present case and others recited in the authorities that we have been referred to.
- Not a statute: The Microsoft test is not a statutory test. There is no magic to it. It articulates a common sense approach that any court should be able to apply. It confers upon the court or tribunal a broad discretion to approve of the methodology to be used at trial. This is evident from the following terms used in the test: "sufficiently credible or plausible", "some basis in fact", "a realistic prospect of establishing loss on a class-wide basis", "the methodology cannot be purely theoretical or hypothetical", "grounded in the facts of the particular case", "some evidence of the availability of the data to which the methodology is to be applied." The words "sufficiently", "some" (used twice in the test), "grounded", "realistic" and "purely", highlight both the discretion conferred upon the CAT to make a value judgment, but also the relative nature of the exercise.
- The test is counterfactual: The methodology is based upon a counterfactual model of how the market would have operated absent the abuse. It is quintessentially hypothetical and, for this reason, will use assumptions and models and, frequently, regression analysis. It is therefore not a fair criticism to make of a methodology that it is hypothetical; though, equally, the CAT will expect to see "some" factual basis for the assumptions and models deployed, hence also the reference in Microsoft to the methodology not being "purely" theoretical or hypothetical.
- Absence of disclosure: The methodology is subject to a certification assessment prior to disclosure and is thereby necessarily provisional and might, properly, identify refinements and further work to be carried out after disclosure. In many competition cases there will be a distinct informational asymmetry between a claimant and a defendant which might be exacerbated in aggregate damages, top down, cases where the relevant information might predominantly be in the possession of the defendant. At the certification stage all that might be possible is for the class representative to advance a methodology identifying what might be done following disclosure. This is why in Microsoft the Court referred, in prospective terms, to there being "some evidence of the availability of the data to which the methodology is to be applied."
- Issues not answers: At the certification stage the methodology must identify the issues, not the answers. The CAT is concerned to identify the issues and gauge whether the methodology proposed for determining those issues is workable at trial when the issues are tested and might lead to different answers, some in favour of defendants. Because of this the CAT will wish to assess whether, if the defendants do win on some issues at trial, the methodology is capable of being adjusted so as to reflect only partial victory by the class.
- Intuition and common sense: Judges are expected to use their common sense. In this case the acceptance by the CAT of the assumption made by the expert, Mr Holt, that Travelcard holders could be assumed, rationally, to wish to pay the lowest possible fare is an example of the CAT arriving at a conclusion it considered was common sense or "informed guesswork". The validity of this approach has repeatedly been endorsed in case law: see e.g., Merricks (ibid) paragraphs [48] – [51].
- The breadth of the axe and the nature of the claim: In forming its judgment at the certification stage the CAT will bear in mind that at trial it is armed with a broad axe by which it can fill gaps and plug lacunae in the methodology. The axe head is adjustable and can expand and retract to meet the nature of the case. There might be less work for it to do in a case of a (relatively) straightforward counterfactual than in the case of a more complex one. In the present case the counterfactual might be relatively straightforward. At the risk of over-simplification, it is that in a journey from the start point within London (A) to the boundary (B) and then onwards to the destination (C) a consumer with a Travelcard is not charged for the A-B leg. In this case there already exists quite a lot of data capable of setting the starting parameters of the claim. Much of this is set out in the expert report of Mr Holt. More will become available following disclosure. At trial the CAT might be able to adjust the use of the data, for instance, by reducing the scope of the class and/or claim if the TOCs are correct that certain categories of the class should be excluded or that certain types of fare should not be subject to further reduction at the behest of Travelcard holders. If the data is relatively complete the CAT might not need to use the axe a great deal. However, in a claim by (say) indirect consumers in a pass-on case, the amount of available hard data might be far less at the certification stage (and indeed throughout the proceedings). The CAT might therefore be less demanding at the certification stage in the knowledge that the axe head can be expanded to facilitate the achievement of practical justice at later stages of the litigation.
- The axe and liability: The appellants argued that the broad axe did not apply to liability issues and that there was no authority establishing that it did. This misunderstands the purpose of the axe. It is not so much a substantive principle of law as a description of a well-established judicial practice whereby judges eschew artificial demands for precision and the production of comprehensive evidence on all issues and instead use their forensic skills to do the best they can with limited material to achieve practical justice. It was a term coined long before the introduction of the overriding objective into the Civil Procedure Rules but has continued vibrancy through that objective and its instruction to judges to act proportionately in the conduct of litigation having regard to the sums involved, the importance of the case, complexity, the financial position of the parties, and the need for expedition and fairness, etc. It was also a term coined long before Parliament conceived of collective redress mechanisms: see e.g. Sainsbury's Supermarkets Ltd v Mastercard Inc [2020] UKSC 24 at paragraphs [217] and [218] ("Sainsbury's") and the cases cited therein. The Supreme Court there treated the broad axe as a function of common law pragmatism: "The common law takes a pragmatic view of the degree of certainty with which damages must be pleaded and proved." The duty of the judge to do the best possible with the evidence available applies as equally to issues of causation and loss (liability) as it does to other issues relating to quantum. Further, when the appellants argued that there was no authority applying the broad axe to liability this assumed that Merricks, where the Supreme Court endorsed the use of the broad axe technique (see (ibid) paragraph [51]), was not a liability case. But as we have set out above, it was (see paragraphs [31] - [32] above).
- The test is about practical justiciability: Canadian case law suggests that when a decision is taken as to the methodology proposed the CAT is seeking, in broad terms, to determine whether that methodology will "advance the resolution" of the issues at trial and enable the court to determine the issue. These propositions were endorsed by the CAT judgment: paragraphs [102] – [104] citing the Canadian Supreme Court in Pioneer v Godfrey 2019 SCC 42 at paragraphs [107] – [109] and Vivendi Canada Inv v Dell'Aniello 2014 SCC 1 at paragraphs [45] and [46]. We agree that a central consideration for the CAT when scrutinising a methodology under the Microsoft test is to decide whether it is workable at trial, but always bearing in mind that the CAT has the power to wield its broad axe and work, in a relatively rough and ready way, with assumptions and common sense intuitions, and that it can permit or even require adjustments to the methodology prior to and at trial.
- The height of the bar: In Merricks Lord Briggs, for the majority, stated of the test, that the threshold for certification was not onerous not least because it had to be formulated in advance of disclosure (ibid paragraphs [40] – [42]). We do not demur but it is necessary to put this into context. The Court was not intending to indicate that the Microsoft test was toothless, or that the CAT would not closely scrutinise the methodology proposed by class representatives for the purpose of obtaining certification. The aggregate damages regime represents a paradigm shift in the dynamics of tortious recovery. A defendant subject to an award is required to disgorge the total loss flowing from its breach. This contrasts with the pre-existing position whereby a dominant undertaking exploiting its position through the imposition of (say) unfair prices on consumers was in practice immunised from the adverse consequences of its breach by the lack of any realistic ability or incentive for a small consumer to take on the dominant undertaking in litigation. The introduction of the collective action and aggregation mechanisms reversed the landscape and has in consequence materially heightened litigation risk for undertakings. The CAT therefore plays an important gatekeeper role in certifying claims and will always vigilantly perform that function (judgment paragraph [12]). It will seek to strike an appropriate balance between the right of the class to seek vindication and the right of defendants not to be subject to a top down claim unless it is a proper one to proceed.
- Calling members of the class: The appellants criticise the class representative for not being prepared to put up class members as witnesses to support the methodology. This is misplaced. The logic behind an opt-out order is that the representatives of the class will not have contact with class members at any point prior to distribution and in an aggregate damages case not only is the CAT forgiven the task of considering individual evidence but the probative value of evidence from a small handful of carefully selected consumers out of millions might be strictly limited. The class representative is not prohibited from looking to the class representative, for instance to answer a survey. But the CAT is unlikely to be moved by a generic complaint that the class representative is not calling individual members.
- De minimis or nominal claims: The appellants also argue that in determining the divide between loss and no-loss the CAT must take into account that many claims are de minimis. Quantum should be limited to those individuals who would be awarded more than nominal damages and the methodology must cater for this. Figures set out in Mr Holt's report indicated that some consumers might have suffered losses equivalent to the price of a takeaway cappuccino. The methodology failed to winnow out such claims from quantum. Mr Moser QC, relaying an observation of Mr Gutmann, retorted that for some consumers even a cup of takeaway coffee is meaningful but that in any event such marginal cases were extreme and unrepresentative. We approach the issue from first principles. First, by their nature collective actions are often brought on behalf of consumers who suffer small individual losses from a breach. The facilitation of such claims is part of the justification for the existence of collective redress regimes. A top down, aggregate, claim serves to ensure disgorgement of the fruits of the breach. In mass consumer claims quantum might characteristically be calculated by multiplying very small numbers (the individual claim) with very large numbers (the class) to arrive at a substantial aggregate award. An analysis of whether a claim or category of claims might be nominal or de minimis forms no part of such an exercise. There is no logic in the CAT calculating an aggregate award which is the sum of a multitude of small claims but then slicing off a percentage to reflect the fact that some (or even most) of the claims are small. To allow this would derogate from a central purpose behind the regime which is to vindicate the collective rights of consumers sustaining small losses. Secondly, and in any event, courts do not refuse compensation to those who only suffer very small losses from a breach. Nominal damages are paid to those who suffer no loss but in favour of whom the court nonetheless orders a small payment to reflect and mark the breach. The courts do order damages where the amount is small but nonetheless discernible (see generally McGregor on Damages (20th edition, 2017) paragraphs 12-001ff). For these reasons in a top down exercise no deductions are made upon the basis that some of the class will have suffered only small losses and there is therefore no requirement for a methodology to address this under the Microsoft test.
- With these considerations in mind, we turn now to the survey issue and the criticisms made of the methodology which we have summarised at paragraph [48] above. We do not accept these submissions.
- First, in its judgment (paragraphs [140] – [164]) the CAT set out a detailed summary of the methodology assessing it against the Microsoft test. It stripped it down into its constituent stages and set out its conclusions on the main issues in dispute between the parties. The starting point therefore is that the CAT applied the correct test in law. It did not take into account irrelevant considerations nor did it ignore relevant matters. In an area where this court accords to the CAT a broad margin of judgment and discretion the fact that the challenge is to the CAT's evaluation of conflicting economic evidence which involves a forward looking counterfactual assessment of how issues will unfold at trial, after disclosure, means that the hurdle for showing an error of law is high. To be fair Mr Jowell QC for First MTR and Stagecoach did not shrink from an acceptance that this was the task confronting the appellants.
- Secondly, the nature of the burden confronting a claimant is important under the Microsoft test. The issue relating to surveys concerns an estimate of Travelcard holdings. It is clear from the 1st expert report of Mr Holt that he had addressed this relying upon a variety of different data sources. However, he suggested that the data could be improved by use of a survey. This came under sustained criticism from the defendants who argued that the sources relied upon would not properly capture historical Travelcard holding patterns or the overlap between such holdings and TOC ticket purchase. In a second report Mr Holt addressed these concerns. He also set out, in detail, how a survey would be carried out. He described the methodology including its target population, the sorts of questions that would be asked, and how the results would be interpreted. He also set out the adjustments that would be made to take account of other variables. At paragraphs [162] and [163] the CAT emphatically, and in our judgment correctly, rejected the TOCs' criticism making the point that at the certification stage what was required was for the expert to "… explain the methodology proposed and indicate the available sources of data to which it will be applied, but … not … provide detailed elaboration of the way the analysis or analyses will be conducted." Demands from the TOCs that the methodology should go further were "disproportionate" and "wholly misconceived":
- Thirdly, the CAT went to pains to satisfy itself during the certification hearing that at trial the methodology could be adapted so as to reflect, for instance, issues upon which the defendants might be successful. For example, Mr Holt was questioned from the witness box by the CAT panel, and in particular by its economist member (Professor Mason), about various aspects of the methodology including whether it would be possible to exclude from aggregate damages certain fares or customers at trial. The exchange focused upon so-called point-to-point tickets. The purpose of the exchange was so that the CAT could satisfy itself that it had understood the methodology and how it could be adjusted at trial. This reinforces our conclusion that the CAT exercised a vigilant gatekeeper role and went to proper lengths to satisfy itself as to the robustness and fitness for purpose of the class representative's methodology[5].
- Fourthly, the transcript of the questioning of Mr Holt involved him explaining how his estimates would need to be perfected following disclosure. The CAT accepted that the methodology was based upon data that might be sub-optimal but took into account that at the certification stage disclosure was yet to occur. This was a relevant conclusion which was well within the CAT's margin of judgment to consider.
- With respect to the appellants' forceful arguments, it is our judgment that the challenge under this heading does not raise an arguable point of law. It merely reflects disagreement with the expert evaluation of the CAT. We reject this ground of challenge.
- We turn to the second ground of challenge. Boiled down to bare essentials it can be summarised in the following way. The expert methodology took as a starting assumption that no rational consumer would wish to pay more than was absolutely necessary. This enabled the class representative to devise a methodology that ignored consumers who did not wish to purchase Boundary Fares and certain types of journey for which a Boundary Fare was said by the TOCs to be inappropriate. Because of this assumption the methodology took as defining parameters: (i) the total number of Travelcard holders; and (ii) the total number of journeys made by such Travelcard holders where no Boundary Fare was offered. The CAT endorsed the assumption as valid as a starting point for the purpose of certifying the methodology (judgment paragraph [158]).
- The appellants argue that the CAT erred in approving this assumption. There were a range of categories of situation where passengers freely and deliberately chose not to use a Travelcard to obtain the best fare and as such they suffered no loss from any failure on the part of the TOC to offer such a fare. By permitting the class to build a methodology upon a hypothetical and assumed foundation it was, in effect, reversing the burden of proof because to succeed the burden now lay with the defendants to prove that there was no loss, rather than with the class to prove that there was loss. It created an unacceptable form of strict liability and could lead to an unfair and unprincipled overcompensation of the class. The categories identified were as follows:
- In oral argument Mr Jowell QC, for First MTR and Stagecoach, gave a series of examples which he said represented further cases where it could not be said that there was an abuse: a consumer at a TVM who failed to select a Boundary Fare through no fault of the TOC; a consumer who purchased a ticket at a ticket desk but who failed to mention his or her Travelcard and; a consumer who mentioned the Travelcard but when offered a Boundary Fare deliberately chose to buy a higher priced ticket. All the categories set out above and the examples given by Mr Jowell QC highlight different issues. Some are related to the scope and effect of the alleged abuse, others are related to the scope of the defined class and some are related to the conduct of the consumer. The argument goes to whether breach and liability issues are sufficiently "common" and, in consequence, whether the proceedings are "suitable" for certification.
- With one exception (concerning point-to-point fares – category (iii) which the CAT accepted should be carved out), the CAT analysed each of these categories rejecting, for a variety of different reasons, the argument that they were unsuited to being common issues for trial or rendered the proceedings unsuitable for certification. The starting points for the CAT's analysis were the broad propositions that: (i) the existence of some no-loss claimants in a class was not an obstacle to certification, and (ii) the interests of defendants could be catered for at trial by adjustments using sensible estimations and assumptions:
- In our judgment this was the appropriate point of departure. It recognises that a starting methodology will rarely, if ever, reflect a perfect blueprint for the trial and that rough edges can be smoothed by the court making adjustments in due course, including at trial using broad axe powers. Over and above this the CAT did proceed (in paragraphs [127] – [134]) to consider each of the categories and save in relation to point-to-point fares (paragraphs [132] - [134]) considered that the categories were not as relevant or significant as was suggested. We can identify no error in this analysis, and we do not repeat here the CAT's assessment. We do however add some limited conclusions of our own in response to specific arguments arising during the appeal which focus upon the assumptions made by the appellants as to what amounts to an abuse.
- First, some of the categories (e.g. (vi) and (vii)) assume that the counterfactual is a market in which to avoid acting abusively the TOCs need only offer choices of fares i.e. permit consumers to pay more if they wish to. That being so if consumers choose to pay more (because for instance they do not care about price optimisation or are in a hurry) the TOCs could not be held responsible for the loss flowing from this deliberate consumer decision. The determination of the correct counterfactual will be an issue for trial, but it is in our view arguable that in the correct counterfactual the only way to avoid an abuse is for the TOC to create a system where there is no material possibility that the Travelcard holder pays more than the Boundary Fare. If the duty of the TOC is simply to deduct Travelcard pre-payments from the ticket price, then the possibility that consumers choose to pay more than the Boundary Fare is eliminated or at least vastly reduced. In this no-abuse counterfactual when a consumer goes to a TVM to buy a ticket it will be swift, easy and automatic for the consumer to ensure that the TVM charges a sum for the journey reflecting the Travelcard prepayment[6]. Put shortly we are not convinced that the issue is about choice but, instead, is about the making of automatic deductions. Mr Jowell QC for First MTR and Stagecoach submitted that it was not as simple as we appeared to believe and that there were many obstacles lying in the way of the coding of the software in TVMs to achieve straightforward, simple, and automatic deduction of the pre-payment reflected in the possession of the Travelcard. We saw no evidence which established this proposition but such matters will be for the CAT to consider at trial both as to their technical correctness but also as to their relevance, even if correct.
- Secondly, the appellants assume that ostensibly irrational choices made by consumers may nonetheless be relevant: see the examples at paragraph [72] above. In the counterfactual however there would be a very high degree of transparency which would ensure the ready availability of comprehensive and accessible information about Boundary Fares and how to purchase them. Granted, there might be occasions when a consumer acts perversely, but these will or should be very rare and if the system is constructed so that the Travelcard pre-payment is also deducted at source the scope for even irrational decision making by consumers should be largely eliminated.
- Thirdly, categories (i) and (ii) (in paragraph [71] above) assume that there will be no abuse if another ticket for the full journey (such as an Advance Fare) may have been cheaper than a Boundary Fare. We analyse this in paragraphs [111] – [114] below and doubt the premise behind the proposition. But, even if the appellants are correct, as the CAT has observed, adjustments can be made at trial for example to exclude such fares from the quantum calculation.
- In argument the appellants raised the spectre that absent a detailed methodology to deal with these matters there was a real risk that any order for damages would be unfair to the defendants and would overcompensate the class. We disagree. This argument would only hold water if the CAT was unable to make adjustments at trial to take account of issues the defendants prevail upon. However, the CAT is alive to the need to do just this so as to avoid the risk of unfair overcompensation. Mr Moser QC made the valid point that the CAT might adopt a "conservative" (pro-defendant) approach to deductions. If (say) it was of the view that there was a category of person who had suffered no loss which accounted for between 2 – 3 % of the total class, the CAT might choose to reduce the total aggregate damages by a sum reflecting 3%, so as to err on the side of caution. At all events it is clear to us that the CAT is perfectly capable, making ample use of its broad axe and applying its acquired and evolving expertise, of making such adjustment as it sees fit to preclude over-compensation.
- In conclusion we reject this ground of appeal.
- In considering suitability the CAT held that the overall cost/benefit balance was "slightly" against certification (judgment paragraph [178]). However, and taking into account other considerations, the CAT nonetheless made the CPO. First MTR and Stagecoach argue that the CAT failed to attach sufficient weight, when considering suitability, to the fact that the collective proceedings would be "… hugely expensive, and overwhelmingly for the benefit of funders and lawyers". They point to the likelihood that, if the CAT makes an award of damages, few consumers will come forward to claim the paltry sums on offer and in any event even legitimate claimants will confront difficulties of proof, e.g. in presenting a valid ticket for travel.
- One component of a cost/benefit analysis involves assessing the costs predicted to be incurred by the class representative. The CAT noted that the costs budget of the class representative for the litigation was just over £11 million (judgment paragraph [48]). This included an assessment of costs for the certification stage of c£660,000. However, when, following the judgment, the class representative came to apply for the costs of the certification hearing they claimed a sum of c£1.94 million, over three times the budgeted figure. In its subsequent ruling on ancillary matters, the CAT expressed the view that this was "staggering".
- It is now argued that this shows that the initial cost budget may prove to be an underestimate. When it came to a judgment on cost/benefit the CAT therefore worked with out of date and materially inaccurate information and as such it proceeded upon a basis which was tainted by an error of law. Had the CAT been in possession of an accurate cost projection, given the marginal nature of the decision, it might not have made the CPO.
- By way of preface to our conclusions we acknowledge that it is important for the CAT to exercise close control over costs. There are conflicting considerations at play. On the one hand to enable mass consumer actions to be viable at all will invariably necessitate the assistance of third-party funders (see the discussion in Le Patourel (ibid) at paragraphs [75] – [80]) and the CAT must therefore recognise that litigation funding is a business and funders will, legitimately, seek a return upon their investment. On the other hand there is a risk that the system perversely incentivises the incurring or claiming of disproportionately high costs. And there is also the risk, highlighted in Canadian literature, that third-party funders have an incentive to sue and settle quickly, for sums materially less than the likely aggregate award. This, if true, risks undermining important policy objectives behind the legislation which include properly rewarding the class and creating ex ante incentives upon undertakings to comply with the law[7].
- The submission was touched upon only briefly during the oral hearing. We do not accept it. There are three points we would make.
- First, the appellants accept that the information now relied upon was unavailable to the CAT during the certification hearing and no blame is therefore attached to the Tribunal. It is raised, in effect, as fresh evidence upon the appeal. However, no application has ever been made to the CAT inviting it to reconsider its substantive judgment on certification in the light of this fresh evidence and there is no material evidence before us as to the reasons for the increase in budgeted costs or as to the implications of any increase for the overall cost budget. For all we know the increase might be justified and/or have no material effect or impact upon the overall budget. In these circumstances we do not consider it appropriate to adjudicate upon the matter. We do not consider that an issue of law properly arises for our determination.
- Secondly, in any event, the answer to concerns such as those expressed lies in the close supervision of costs by the CAT to ensure that they are proportionate: see Le Patourel (ibid) paragraph [78]. The proffering of an exorbitant costs budget does not mean that those costs will be ordered to be paid if the class prevails at trial; and the mere fact that at the certification stage costs seem high does not mean that the CAT will simply accept that figure as appropriate for the purposes of a cost/benefit analysis. We cannot see that the CAT would therefore necessarily have taken any materially different view of suitability had it known of the most up to date costs figures.
- Thirdly, as to the appellants' pessimistic prognosis that an award will not be claimed, this is an untested premise. It assumes that the CAT lacks the ability to find creative ways of ensuring that the award is distributed so as to maximise the benefit to relevant consumers. Once an award has been made the choice of distribution is binary and lies between distribution to the class and distribution to the selected charity. Whilst we express no decided position upon the issue it certainly seems arguable that it is open to the CAT, if it accepts the appellants' gloomy forecast, to consider whether there are appropriate proxies to distribution to individual claimants such as ordering a prospective reduction in certain fares upon the basis that if it is impossible from a practical perspective to cure the past then a forward-looking remedy might suffice. This might be because it would capture a substantial portion of the consumers who had sustained a past loss but who, for whatever reason, would not come forward to make a claim, perhaps because, as the appellants argue, they no longer possessed proof of travel. Given the legally binary nature of the choice of distribution – class or charity – then a method of distribution which, albeit in a relatively rough and ready way, goes to future travellers might be a far better fulfilment of the purposes of the collective redress scheme than payment to the nominated charity.
- For all these reasons we reject this ground of appeal.
- The CAT held that a broad formulation of abuse whereby the defendants failed to ensure that the class was not double-charged was arguable and had to go to trial and it refused summarily to dismiss the claim. The core allegation was in the following form:
- The abuse was manifest in two principal ways. First, where Boundary Fares existed, they were not offered from all outlets and/or they were not easily accessible (see paragraphs [17] and [18] above). Secondly, in relation to certain journeys no Boundary Fares were offered at all.
- Section 18 CA 1998 provides that the abuse of a dominant position may consist, inter alia, in directly or indirectly imposing "unfair" prices or other "unfair" trading conditions (see paragraph [3] above). The CAT set out in some detail the relevant law. It concluded that the law on "unfair" abuses was in a state of development and that the categories of abuse were not closed (judgment paragraph [60]). It held that it was neither an extraordinary nor a fanciful proposition to categorise as an abuse a "system operated" by a dominant company which failed to be transparent as to the availability of cheaper alternative prices for the same service (paragraph [64]). The CAT pointed out that in relation to alleged exploitative abuses, which it was the "special responsibility" of dominant companies to avoid, it was relevant that the customers charged were end-consumers (and predominately individuals), as opposed to commercial undertakings (paragraph [65]). It also pointed out that the law was concerned with substance and not form and that the case advanced was not a "dramatic" extension of the law (paragraph [65]). We agree with the CAT's general analysis; it is clearly arguable that for a dominant undertaking to create a system which routinely double-charges consumers may be unfair and abusive.
- In this appeal, two components of the CAT's conclusions are challenged. All appellants challenge the failure of third parties, who sell tickets for travel on the TOCs' services to passengers holding Travelcards, to offer Boundary Fares in relation to discounted fares, such as Advance Fares. The contention is that it is not arguable that such situations reflect abuse. Only LSER challenges the conclusion of the CAT that the failure to offer Boundary Fares in relation to "all" ticket types, and in particular Advance Fares, was arguably abusive.
- The law relating to abuse is concerned with consumer unfairness because when an undertaking is dominant it is, by definition, freed from the competitive shackles which otherwise incentivise and discipline it to maximise consumer welfare and benefit. This is why most laws worldwide which prohibit abuse of dominance include within the prohibition the imposition of some form of "unfair" terms and prices. These are often described as "exploitative" abuses. There is no single definition of unfairness set out in case law. One leading commentary (O'Donoghue and Padilla, "The Law and Economics of Article 102 TFEU", 3rd Edition, 2020), provides a useful summary of the case law (ibid pages [1031] – [1045]) and observes (page [1037]) that the test includes asking whether the disputed term is "reasonable" bearing in mind the legitimate interests of the dominant undertaking, its trading parties and consumers. It is commented that the reasonableness test seems vague but that a more developed definition from case law is one which involves two stages and entails an analysis of (i) whether the disputed term serves a legitimate purpose and if so (ii) whether it is proportionate relative to that purpose.
- Two judgments of the CJEU are of particular relevance. The first is Cases C-147 & 148/97 Deutsche Post ("DP"), EU:C:2000:74. This concerned charges levied by the German postal operator. In accordance with an international agreement, where mail was posted in another European country for delivery in Germany, the German operator recovered "terminal fees" from the operator in the third country. Such charges did not however cover the full cost of delivery. An international bank with a billing operation in Germany arranged to send its regular communications to customers in Germany and elsewhere from The Netherlands where it paid locally set international postal charges. DP claimed postage charges from the international bank at the full internal rate for domestic postage, on the basis that the communications, although posted in the Netherlands originated in Germany. It therefore charged the full rate and did not offset or otherwise account for that part of the service already paid for. On a reference from the German Court the CJEU held that this amounted to an abuse of dominance:
- The second case is Case C-385/07P Duales System Deutschland ("DSD"), EU:C:2009:456. This concerned a Commission decision that DSD, a company operating a system for collecting waste packaging on behalf of manufacturers and distributors, had abused its dominant position. Under German environmental protection laws, manufacturers and distributors of packaged goods were required to put in place arrangements for recovering from consumers sales packaging free of charge. Manufacturers were however exempt from this if they participated in a third party system guaranteeing regular collection throughout their sales territory of used packaging. DSD was the only operator of such a system throughout Germany but there were alternative operators at regional levels. Subscribers to DSD's system would affix DSD's green dot logo to their packaging and DSD would then collect the packaging. The fees charged by DSD were based on all packaging bearing the DGP logo irrespective of whether it was actually collected by DSD as opposed to the manufacturer collecting it themselves or using another third party. Before the Commission DSD argued that manufacturers could elect not to affix the logo to packaging not to be collected by DSD. For various reasons this was rejected by the Commission as economically unrealistic and impractical. A Grand Chamber of the CJEU noted that an abuse of dominance under the Treaty could be constituted by directly or indirectly imposing unfair prices or other unfair trading conditions. The Court then applied a proportionality test whereby the charge was disproportionate to the economic value of the service provided. It held that charging a fee for a service that was not used or wanted was abusive:
- Case 127/73 BRT v SABAM [1974] ECR 313 is another example of conduct by a dominant undertaking that sought something for nothing and which was held to be abusive. It concerned a provision in the terms and conditions set by a copyright collecting society which permitted the society to continue to exercise rights for five years following withdrawal of the member from the society. It was held to be unfair and abusive because it was not "absolutely necessary" to protect a legitimate interest of the dominant undertaking.
- In paragraph [61] of its judgment in the present case the CAT referred to the recent judgment of the Federal Supreme Court in Germany in Facebook, 23rd June 2020, ("Facebook") in which the Court set aside a decision of the first Cartel Panel of the Dusseldorf Higher Regional Court of 26th August 2019 which had suspended, pending a full appeal, a decision of the Bundeskartellamt dated 6th February 2019 (Reference B6-22/16). That decision had been taken under the provisions of German competition law prohibiting the abuse of a dominant position (in Chapter 2 of the "Gesetz gegen Wettbewerbsbeschränkung" or "GWB") which are identical to the Chapter II prohibition. The judgment of the Federal Supreme Court was limited to points of law (ibid paragraph [7]). It strongly endorsed the Bundeskartellamt decision. In Preventx Limited v Royal Mail Group Ltd [2020] EWHC 2276 (Ch) the High Court treated this judgment as illustrative of the broad range of potentially abusive trading conditions that a dominant undertaking might impose (ibid paragraph [88]). It was relied upon by the CAT in the present case to show the potential breadth of section 18 and its ability to challenge a wide range of consumer harms. The judgment in Facebook reflects the application of the reasonableness/proportionality test to a new factual scenario. Nonetheless, there is, in our view, nothing especially startling about the analysis of the Court.
- The Federal Supreme Court judgment[8] summarised the abuse in the following way:
- In paragraph [58] the Court, in rejecting the conclusion of the lower Court that there was no abuse because consumers could choose not to use Facebook at all in order to avoid having to permit Facebook to use their personal data, observed as follows:
- Facebook is an example of an unfair intrusion into consumer rights. It seems on a par with the case law. Further, illustrations of non-price abuse, which also highlight how the law protects consumers against unfair intrusions into their rights, are found in Case T-83/91 Tetra Pak v Commission [1994] ECR II-755 confirmed on appeal in Case C-333/94P [1996] ECR I-5951 ("Tetra Pak"). The case concerned machines and consumables sold by Tetra Pak, a dominant manufacturer of cartons (e.g. for milk). A decision of the Commission finding that many terms and conditions imposed by Tetra Pak were abusive was upheld by the CJEU. These included an absolute right of control over the equipment configuration prohibiting the buyer from adding accessories to the machine or making modifications to it or adding or removing anything from it or even from moving the machine. These terms were unfair because they deprived the owner of "certain aspects of his property rights", and they made the buyer "totally dependent on Tetra Pak's equipment and services". Other clauses concerning the operation and maintenance of the equipment which gave Tetra Pak the exclusive right of maintenance and repair were abusively unfair because they bound the customer to Tetra Pak and precluded maintenance even by the buyer's own repair staff. Clauses requiring the buyer to transfer ownership to Tetra Pak if they wished to sell the machinery and allowing Tetra Pak a right of re-purchase at a pre-ordained price were unfair because they were inconsistent with the buyer's right of ownership.
- A lack of transparency can be an important factor in rendering unlawful that which might otherwise be lawful. In Case 322/81 Michelin [1985] ECR 3461 the Commission found that the dominant undertaking had granted target rebates to its dealer customers which had the effect of tying them to supplies from Michelin and, in consequence, making it harder for smaller rivals to sell to Michelin's customers. The rebates were abusive for a number of reasons one of which was that they were lacking in transparency. The level of rebate applicable to purchases made by a dealer was not transparently set out. Rebates were offered under a system applied after the event and in uncertain and variable amounts. The lack of transparency and resultant uncertainty had the practical effect of making dealers unwilling to purchase from new sources of supply for fear of losing increased rebate and this in effect tied customers to Michelin and created an entry or expansion barrier to rivals. On appeal the CJEU (ibid paragraphs [84] and [85]) upheld the Commission decision. The rebates were abusive because they were part of a "discount system" which was "calculated" to prevent dealers from being able to exercise a free choice as between suppliers. The vice in that case was the exclusionary effect upon rivals to Michelin, not upon the fairness of the terms offered to dealers. Nonetheless, it illustrates how a lack of transparency can be relevant to whether conduct is abusive.
- To show that a term is unfairly abusive it is not always necessary to show that it is causally connected to the dominant position. In some cases it might be possible to establish that absent dominance the undertaking, in all likelihood, would not have been able to impose the term in question and this might be relevant to whether a term is unfair: See e.g. Case 27/76 United Brands v Commission EU:C:1978:22 at paragraphs [248] and [249]. But that is but one means of establishing abuse in cases of consumer harm. In neither DP (ibid) nor DSD (ibid) did the CJEU consider whether the terms in question would have been imposed in a genuinely competitive market. In both cases the Court simply examined the fairness of the disputed term as a standalone proposition. The same point was made in Facebook (ibid) at paragraphs [65ff] of the judgment of the Federal Supreme Court.
- In the light of this review of the case law we turn to the first ground of challenge which concerns whether the defendants are responsible for the conduct of third parties who sell tickets for use of a TOC rail service but who fail to honour Travelcards and/or offer Boundary Fares. This ground of challenge arises only if the defendants are found to be liable for their own conduct. If their own conduct is not abusive, the same conduct by third parties cannot engage the TOCs' liability. As to this LSER argues that third party retailers are licensed by all TOCs acting collectively through the Rail Delivery Group ("RDG"), an industry trade body of which the TOCs, among others, are members. LSER has no individual contract with those third parties. Further, third party sellers compete in various ways with TOCs as regards ticket sales. LSER submitted to the CAT that it: "… could not possibly be liable for any failure by such third parties … to inform customers about the possibility of a Boundary Fare, or to respond adequately to inquiries, since it is in no position to set the terms on which such independent entities sell their tickets". Mr Moser QC disputed this. He argued that the relationship between a TOC and third party outlets was one of agency with the latter selling on behalf of the TOCs as principals. No TOC could escape liability for abusing dominance upon the basis that it used agents to sell its tickets. At base all of this was however arguable and for exploration at trial.
- The CAT held that it was unnecessary at the certification stage to explore the nature of the boundaries of any agency relationship between a TOC and third parties. The position was analogous to the liability of cartelists for "umbrella pricing". This described the situation where cartelists unlawfully agreed to raise prices and were liable not only for the sale at inflated prices of their own, cartelised, products but, insofar as that led to an increase in prices across the market, also for over-priced sales made by producers outside the cartel who adapted their prices (upwards) so as to sit at or just below the cartel prices. This was a principle which was unrelated to principal and agent relations. The CAT cited by way of example Case C-557/12 Kone v ÖBB Infrastruktur, EU:C:2014:1317. The CAT held:
- In our judgment this is clearly an issue for trial. If the third parties are agents, whether selling via some species of collective joint venture or otherwise, then it is hard to see how a TOC can escape liability for abuse simply because it sells via that agent. But if a TOC sells under some different form of relationship then it is also arguable that, since they are assumed to be in a dominant position and have a "special responsibility", it is abusively unfair for them to set up a system (whether by themselves or with other TOCs through the RDG) whereby third parties can act in a manner which would be unfair and abusive if carried out by the TOC. Further, if TOCs have, inter se, under the Travelcard Agreement, an obligation to "honour" Travelcards (see paragraph [14] above) that fact might be relevant to whether when they relinquish responsibility for sales to third parties without ensuring that the third parties do honour Travelcards, they are acting lawfully.
- It was suggested that the TOCs' hands were tied because of the fact that the control over third party sales was via the RDG, a collective body. The suggestion was that because of the complicated web of contracts which governed these collective sales, no individual TOC had control or responsibility over the prices of third parties. We found this surprising and made the point during argument that so far as we were aware: (i) the fact that the rights of a third party seller were governed by contract was, ultimately, a matter of free choice for the TOC and not thereby any sort of a defence; but also (ii), there was no regulatory prohibition upon a TOC taking steps, under contract or otherwise, to ensure that third parties honoured Travelcards. As matters were left at the culmination of the appeal hearing the appellants had not researched whether our assumption that TOCs were not prohibited in law from requiring third parties to honour Travelcards was correct and we were not taken in any detail to the nature of the relationship between TOCs, RDG and third parties. Our intervention did however cause First MTR to make clear that reliance should not be placed on a paragraph in the witness statement evidence of the Head of Revenue & Commercial Strategy at South Western Railway (the trading name of First MTR) which had said that individual TOCs "… cannot require third parties to sell particular fares (including Boundary Fares) or dictate to them how fares should be sold".
- And, once again, it is also arguable in our view, as the CAT concluded, that if because of their abuse (in relation to tickets sold by them) other companies were incentivised or enabled to set prices at levels which were artificially inflated and/or which did not fairly respect Boundary Fares, the TOCs would be liable for that adverse financial consequence. Mr Jowell QC argued that the class representative's expert had not in his methodology addressed the issue of liability for this "umbrella pricing" and the CAT erred in tolerating this omission. We disagree. The level of detail required by the CAT of the alleged abuse was very much a matter for its judgment and discretion. The fact that an issue or sub-issue might not be raised at the certification stage does not mean that later on, for instance following disclosure, it might not be necessary for the expert to revisit the methodology. The CAT did not err in agreeing at the certification stage to the proposed methodology for determining abuse upon the broad basis advanced.
- There might, finally, be other ways of looking at the facts and some were floated during the appeal. Joint dominance briefly raised its head in relation to the activities of RDG.
- Mr Harris QC suggested that an answer to all of this was that the TOCs were in competition with the third-party sellers. We did not have any evidence on this but even if correct it might have only strictly limited relevance. Any competition existing between a TOC and a third party is intra-brand competition i.e. competition within a single dominant brand (i.e. the same network). It is not the more usual sort of competition found in a competitive market which is inter-brand competition i.e. competition between different competing suppliers of different competing services or goods. Such competition as exists – if any (a matter for trial) - would not seem to be an answer.
- We reject this ground of appeal.
- We turn to the second objection of LSER which is that the CAT erred in not summarily dismissing the allegation that a Boundary Fare should have been available in conjunction with "all" ticket types, including in particular Advance Fares. LSER argued that it had a number of promotional fares, such as weekender fares and super off-peak fares, which were heavily discounted and designed to encourage travel on certain routes at times when the network was relatively quiet. The nub of LSER's argument was that where a discounted fare was offered, a similarly discounted Boundary Fare did not have to be made available:
- The CAT rejected this argument (judgment paragraph [74]). It held that: "… a Boundary Fare should not properly be regarded as a discount. It is more appropriately viewed as the fare for the part of a journey not already paid for and covered by a Travelcard." The CAT recognised that in relation to certain discounted fares there might be an argument that Boundary Fares did not have to be applied but concluded that this was an argument to be assessed at trial.
- Standing back the mere fact that a ticket price is discounted, for example an Advance Fare, is not, per se, a reason not to honour a Travelcard. On the contrary, not to do so might amount to reverse discrimination against the card holder. If (say) an Advanced Fare for a journey from central London (A) to the boundary (B) and on to the final destination (C) is priced at £50 and that is the sum charged to all customers regardless of whether they have a Travelcard, that could be reverse discrimination i.e. treating two people (X with a card and Y without a card) who are objectively in different situations, in like manner. If, as the CAT recognised, and as seems to us to be common sense, a Travelcard is a form of pre-payment for a ticket, then to charge X the same as Y is, in substance, to charge X more than Y because X has, already, through paying for the Travelcard, paid for the A-B leg of the A-B-C journey. We note that in DP (see paragraph [94] above) it was an abuse not to deduct automatically a portion of a service already pre-paid. It is of course possible that the situation is more complex and nuanced than we have described but if this is so it will be drawn out from the evidence at trial.
- The respondent accepted before the CAT that some promotional fares might be so deeply discounted that not offering a Boundary Fare in those instances might be proportionate. An illustration was given whereby LSER offered a "Kids for a Quid" fare. The CAT stated that such extreme promotional fares were a minimal part of the total. It considered that the only fare of practical relevance in this context was the Advance Fare. The CAT held nonetheless that if at trial LSER won this or any other analogous argument it would not be difficult to adjust the figure for aggregate damages commensurately. We agree.
- If a dominant undertaking charges a consumer for a service they do not use or need or want or imposes terms which give the dominant undertaking an advantage to which it is not entitled – for example by failing to deduct pre-payments – then this might be unfair and there might be an abuse of dominance. The essential premise in the present case is that the defendants have double-charged consumers for travel and have been enabled to do this by use of a system that is said to be opaque and inaccessible. Whether the TOCs can identify an objective and proportionate justification for this conduct will fall to be tested later in these proceedings. By reference to the case law, all of the various issues raised by the parties are arguable and need to be properly assessed at trial. In our judgment the CAT was clearly correct to hold that the allegations in relation to sales via or by third parties, and "all" fares, including Advance Fares, were arguable and matters for trial and were not to be struck out. We reject these grounds of appeal.
- For all the above reasons, the appeals are dismissed.
Lord Justice Green :
A. Introduction
"18 Abuse of dominant position.
(1) Subject to section 19, any conduct on the part of one or more undertakings which amounts to the abuse of a dominant position in a market is prohibited if it may affect trade within the United Kingdom.
(2) Conduct may, in particular, constitute such an abuse if it consists in—
(a) directly or indirectly imposing unfair purchase or selling prices or other unfair trading conditions;
(b) limiting production, markets or technical development to the prejudice of consumers;
(c) applying dissimilar conditions to equivalent transactions with other trading parties, thereby placing them at a competitive disadvantage;
(d) making the conclusion of contracts subject to acceptance by the other parties of supplementary obligations which, by their nature or according to commercial usage, have no connection with the subject of the contracts.
(3) In this section—
"dominant position" means a dominant position within the United Kingdom; and
"the United Kingdom" means the United Kingdom or any part of it.
(4) The prohibition imposed by subsection (1) is referred to in this Act as "the Chapter II prohibition".
"Class definition
5. The class of persons (the "Class") whose claims are certified for inclusion in the Collective Proceedings includes—
All persons who, at any point during the Relevant Period purchased or paid for a rail fare for themselves and/or another person, which was not a season fare or a Boundary Fare or a fare for the portion of their journey from the last station covered by their Travelcard to their destination, where:
a. the person for whom the fare was purchased held a Travelcard valid for travel within one or several of TfL's fare zones (the "Zones"); and
b. the rail fare was for travel in whole or in part on the services of the Defendant(s) from a station within (but not on the outer boundary of) those Zones to a destination beyond the outer boundary of those Zones (including fares for return journeys).
Whereby:
"Relevant Period" shall mean the period between 1 October 2015 and, in Case No. 1304/7/7/19, the date of final judgment or earlier settlement of the Claims, or, in Case No. 1305/7/7/19, 2am on 17 October 2021;
"Travelcard" shall mean a Transport for London ("TfL") zonal ticket; and
"Boundary Fare" shall mean a fare valid for travel to or from the outer boundaries of TfL's fare zones, intended to be combined with a Travelcard whose validity stretches to the relevant zone boundary."
i) Peak Day Travelcards are valid for travel at any time of day and are available in two combinations covering either zones 1 – 4 or zones 1 – 6;
ii) Off-peak Day Travelcards are valid for travel at any time after 9.30am on weekdays and at any time at weekends and public holidays but are available only for zones 1 – 6;
iii) Seven day or longer Travelcards are valid for travel at any time and are available in any combination of two or more adjoining zones.
"…the Operators will be operating passenger rail services and will be required to provide and honour Travelcards".
(Emphasis added)
"26. The Applicant refers to a 'mystery shopper' survey that he commissioned from the consumer research consultancy Decidedly (now Yonder) that was conducted in December 2018 whereby a team of researchers made over 400 enquiries at ticket counters during different operating hours at a selection of stations served by First MTR, and similarly at a selection of stations served by LSER, and explored other available sales channels including the Respondents' and third party websites, mobile phone apps and telephone-based services. The Decidedly survey report found that:
(1) at the TOC ticket counters, where a Travelcard was not initially mentioned, for First MTR 89.4% of enquiries and for LSER 83.5% of enquiries led to the clerk quoting a full journey price without asking about ownership of a Travelcard; and that where a Travelcard/Boundary Fare was mentioned by the customer, for First MTR in only 71.7% of cases and for LSER in only 58.2% of cases was the Travelcard incorporated into the ticket price quoted.
(2) at the First MTR in-station TVMs, although Boundary Fares are available, the purchase option was complicated and the 'mystery shoppers' were not always able to locate it without assistance. As noted above, Boundary Fares are not available from LSER's TVMs;
(3) Boundary Fares were not available through any of the surveyed online sales outlets (including mobile phone apps) whether operated by First MTR, LSER or third parties, including Trainline.com;
(4) of the selected third-party telephone-based sellers (Trainline and TrainGenius), there was low staff awareness of Boundary Fares and in the case of TrainGenius they were not able to sell them."
The lack of availability of Boundary Fares was said to be "compounded by an almost complete absence of any consumer-facing information regarding the existence or use of those fares…".
"By failing to make Boundary Fares sufficiently available for sale and/or failing to use their best endeavours to ensure that there was a general awareness among their customers of the existence of Boundary Fares so as to enable customers to buy an appropriate fare in order to avoid being charged twice for part of a journey the Defendants abused their position of dominance on the relevant market in breach of the prohibition in section 18 of the Act…"
"As an undertaking in a dominant position the defendants have a responsibility to ensure inter alia that their customers are not subjected to unfair prices or unfair trading conditions. This includes a responsibility to avoid, or to remedy, circumstances which effectively compel customers to pay a second time for part of the service provided to them in respect of which they already hold a valid ticket (a Travelcard); in particular given that the First Defendant received a share of the revenue from the sale of Travelcards under an agreement with TfL. Furthermore, the Infringement occurred against a backdrop where the Defendants must have been well aware, from data readily available to them, but only an unrealistically low number of Boundary Fares were being sold for travel on their services."
B. The collective redress system in a nutshell
"(2) The Tribunal may make an award of damages in collective proceedings without undertaking an assessment of the amount of damages recoverable in respect of the claim of each represented person."
When the power is exercised the focus of the CAT is not therefore upon sums lost by individuals. The section does not explain how, otherwise, damages are to be calculated. Nonetheless, it is clear that this is by reference to the total, aggregate, damages flowing from the breach. This is described as a "top down" approach to be contrasted with the traditional "bottom up" approach (which would apply if the power is not exercised) whereby the loss sustained by each individual claimant flowing from a breach is assessed and made the subject of an award. The evidence needed to calculate top down damages is intrinsically different to that needed to assess bottom up damages. How an aggregate award of damages is to be divided up as between the class is the subject of a later distribution stage which occurs following an award of damages, at which point in time quantum has been fixed (Le Patourel paragraphs [41] – [45]).
C. The Issues
i) Issue I: Scope of section 47C(2) – aggregation of liability: Does section 47C(2) CA 1998 permit issues relating to liability (i.e. causation and proof of some loss) to be determined upon an aggregate top down basis or must the position of each member of the class be assessed individually?
ii) Issue II: The Microsoft test: Whether, if section 47C(2) does cover liability and quantum, the CAT erred in approving the methodology proposed by the class representative in the light of the Microsoft test.
iii) Issue III: Cost/ benefit analysis and costs budgeting: Whether the CAT erred in concluding that the conclusion that the cost/benefit assessment was "slightly" against the making of the CPO did not mean that it should refrain from ordering a CPO.
iv) Issue IV: Abuse and unfairness: Whether the CAT erred in refusing to dismiss as unarguable that part of the claim which alleged abuse by TOCs arising from: (i) the failure of third parties selling LSER tickets to honour Travelcards; and (ii) the failure by the defendants to offer Boundary Fares in "all" cases, and in particular in respect of Advance Fares.
D. Issue I: Scope of section 47C(2): Aggregation of liability?
The Issue / The appellants' arguments
Judicial guidance on section 47C(2)
"45. A critical issue in deciding whether the proposed methodology is a suitable and effective means of calculating loss to the class is to determine whether it is necessary to prove at trial that each member of the proposed class has in fact suffered some loss due to the alleged infringement. Although the expert evidence must obviously provide a means of calculating the level of pass-on of the MIFs from merchants to consumers via price, there is some controversy as to whether that is sufficient to make the global loss suffered by consumers a common issue absent being able to show that each member of the class was in some way adversely affected in their own purchases during the infringement period.
…..
47. To require each individual claimant to establish loss in relation to his or her own spending and therefore to base eligibility under Rule 79 on a comparison of each individual claim would, as I have said, run counter to the provisions of s.47C(2) and require an analysis of the pass-on to individual consumers at a detailed individual level which is unnecessary when what is claimed is an aggregate award. Pass-on to consumers generally satisfies the test of commonality of issue necessary for certification."
Factual distinctions
The natural interpretation of the language of Section 47C(2)
Canadian law works well without a system of aggregated liability
"107. As regards the common issues, the Canadian Supreme Court has set out the following principles which we think can appropriately be applied under the UK regime:
(1) the common issues requirement should be interpreted purposively, having regard to the object of the collective proceedings regime: Dutton, Microsoft;
(2) it is not necessary for common issues to predominate over non-common issues, but if several significant issues are common issues, that will favour certification: Dutton, Microsoft, and see Merricks SC at [65]- [66];
(3) a common issue does not require that all members of the class have the same interest in its resolution. The commonality refers to the question not the answer, and there can be a significant level of difference between the position of class members. Therefore the question may receive varied and nuanced answers depending on the situation of different class members, so long as the issue advances the litigation as a whole: Vivendi, Godfrey; and
(4) the standard to be applied in assessing expert evidence designed to show a common issue is that it must be sufficiently credible or plausible to establish some basis in fact for the commonality requirement and that it is not purely theoretical but grounded in the facts of the particular case in question, with some evidence of the availability of the data to which the methodology is to be applied, i.e. the Microsoft test; but this is not an onerous evidential test: see Merricks SC at [40]-[42].
108. However, there are also important distinctions between the Canadian regimes and that of the UK:
(1) "Common issue" is the statutory term used in the legislation of the Canadian common law provinces. That expression does not appear in the UK statute which refers to the requirement for "the same, similar or related issues of fact or law" and "common issue" is used in the CAT Rules only as a shorthand for the statutory term: rule 73(2). The UK statutory wording corresponds to the formulation used in the Quebec class proceedings statute ("identical, similar or related questions of law or fact"), and in Vivendi the Supreme Court of Canada pointed out that this is a broader and more flexible concept than "common issues" as used in e.g. the Ontario and British Columbia CPAs. The judgment states, at para 53: "… It would be difficult to argue that a question that is merely "related" or "similar" could always meet the "common issue" requirement of the common law provinces. The test that applies in Quebec law therefore seems to be less stringent."
(2) The approach of the Canadian courts has frequently been to segment the proceedings between a "common issues trial" to be followed by trials of the individual issues. Although that is certainly possible for collective proceedings in the UK pursuant to rule 74(6) – see the Guide at para 47 6.37 – it is not expected to be the approach where the class representative puts forward a tenable claim for aggregate damages.
(3) Related to (2) above, the statutory framework for aggregate damages in these cases is very different between the Canadian common law provinces and the UK. For example, s 29(1)-(2) of the British Columbia CPA provide:
'29(1) The court may make an order for an aggregate monetary award in respect of all or any part of a defendant's liability to class members and may give judgment accordingly if (a) monetary relief is claimed on behalf of some or all class members, (b) no questions of fact or law other than those relating to the assessment of monetary relief remain to be determined in order to establish the amount of the defendant's monetary liability, and (c) the aggregate or a part of the defendant's liability to some or all class members can reasonably be determined without proof by individual class members.
(2) Before making an order under subsection (1), the court must provide the defendant with an opportunity to make submissions to the court in respect of any matter touching on the proposed order including, without limitation, (a) submissions that contest the merits or amount of an award under that subsection, and (b) submissions that individual proof of monetary relief is required due to the individual nature of the relief.'
Material parts of that provision, and in particular s. 29(1)(b) and (2)(b), are in sharp contrast to s. 47C(2) CA: see para 43 above."
Conclusion
E. Issue II: Whether the class representative's expert methodology met the Microsoft test
The Issue
The methodology to be applied: The Microsoft test
"In my view, the expert methodology must be sufficiently credible or plausible to establish some basis in fact for the commonality requirement. This means that the methodology must offer a realistic prospect of establishing loss on a class-wide basis so that, if the overcharge is eventually established at the trial of the common issues, there is a means by which to demonstrate that it is common to the class (i.e. that passing on has occurred). The methodology cannot be purely theoretical or hypothetical but must be grounded in the facts of the particular case in question. There must be some evidence of the availability of the data to which the methodology is to be applied."
The competing submissions
Observations on the Microsoft test
The survey issue
"162. We recognise, as both Mr Ward and Mr Harris emphasised, that the proposed survey will play a significant role in the quantification of damage. The effective conduct of such a survey may be challenging. But we do not accept Mr Ward's submission that Mr Holt should have designed, at least on a provisional basis, a survey for the purpose of the CPO applications. Expert evidence at this stage should explain the methodology proposed and indicate the available sources of data to which it will be applied, but it does not have to provide detailed elaboration of the way the analysis or analyses will be conducted. As Mr Holt explained, the design of such a survey will be made by those with particular skill in that field, which we consider is entirely reasonable. It would be wholly disproportionate to expect a CPO applicant to engage survey consultants and produce their evidence at the certification stage.
163. Mr Harris further submitted that for the survey to be representative it would have to be carried out, "as a bare minimum", at every origin station within the two networks; and probably also at all stations on routes where a passenger can transfer from the tube, DLR or other train service without returning to the station entry-hall or concourse. We regard those submissions as wholly misconceived. Properly constructed and conducted surveys of relatively small samples are widely used to gain representative evidence, including in the field of public transport. …"
The use of surveys in competition cases is unremarkable. Mr Moser QC pointed out that even the TOCs had used surveys as part of their internal analysis of apportionment factors under the Travelcard Agreement (see paragraph [15] above). At base, the conclusion of the CAT as to the level of detail required at the certification stage was one for its legitimate discretion.
The assumptions issue
"(i) another ticket for the full journey may have been cheaper than a Boundary Fare, for instance a discounted, advance ticket;
(ii) the passenger may have been able to achieve some other preferable, alternative discount, for instance a group discount;
(iii) another point-to-point ticket from somewhere in the outer zone of the validity of the passenger's Travelcard to the destination may have been cheaper than (or the same price as) the equivalent Boundary Fare;
(iv) the passenger may not have had his/her Travelcard available at the moment of purchase and/or at the time of travel;
(v) the passenger may have had a Travelcard that was not valid for the requisite period (for instance, the passenger had a 7-day Travelcard, but wanted to return in a fortnight's time, or was not sure when s/he was planning to return);
(vi) the passenger may not have had the time or inclination (for a very small absolute saving) to devote any extra effort to choosing and buying a Boundary Fare e.g. because s/he was in a hurry and/or was going to be reimbursed anyway (bearing in mind that the proposed class includes business purchases);
(vii) more widely, the passenger may not have cared about price optimisation to begin with, especially for a small absolute amount and/or if being reimbursed."
"… we consider that the various examples do not preclude the issues we have identified from being common issues as the term is explained above. Almost any class action will include some claimants who suffered no loss: e.g. see para 112 above regarding Merricks. We think it would create an unfortunate obstacle to an effective regime for collective proceedings if potential defendants could sustain objections to the eligibility condition based on speculative examples. Where appropriate, the interests of the defendant can be protected by making some reduction in the aggregate damages award, based on reasonable estimation or assumption".
Conclusion
F. Ground III: Cost/ benefit analysis and costs budgeting: Whether the CAT erred in concluding that the conclusion that the cost/benefit assessment was "slightly" against the making of the CPO did not mean that it should not order a CPO.
The issue
Introductory observations
Analysis
Conclusion
G. Ground IV: Strike out/summary judgment on abuse in relation to (i) agents and (ii) the failure to make Boundary Fares available for all ticket types
The issue
"The Infringement consists in a breach by the Proposed Defendants of the Chapter II prohibition. In summary, the Proposed Class Representative's case on … abuse is as follows:
…
Abuse: The abuse, which is continuing, consists in the Proposed Defendants' neglecting of their special responsibility as dominant undertakings through failing to take any or sufficient steps to prevent Class Members from being double-charged for part of the service provided to them. In practice, the abuse consists in failing to make Boundary Fares sufficiently available for sale, and/or failing to ensure, for example through better staff training, amended sales procedures, or increased customer-facing information, that customers are aware of the existence of Boundary Fares and buy an appropriate fare which avoids them being charged twice for part of their journeys."
The law on abuse by the imposition of unfair prices or other unfair trading conditions
"57. … a body such as Deutsche Post which has a statutory monopoly over a substantial part of the common market may be regarded as holding a dominant position within the meaning of Article 86 of the Treaty.
58. Thus, the exercise by such a body of the right to demand the full amount of the internal postage, where the costs relating to the forwarding and delivery of mail posted in large quantities with the postal services of a Member State other than the State in which both the senders and the addressees of that mail are resident are not offset by the terminal dues paid by those services, may be regarded as an abuse of a dominant position within the meaning of Article 86 of the Treaty.
59. In order to prevent a body such as Deutsche Post from exercising its right, provided for by Article 25(3) of the [Universal Postal Convention] to return items of mail to origin, the senders of those items have no choice but to pay the full amount of the internal postage. …
61. It follows from all the foregoing considerations that, in the absence of an agreement between the postal services of the Member States concerned fixing terminal dues in relation to the actual costs of processing and delivering incoming trans-border mail, it is not contrary to Article 90 of the Treaty, read in conjunction with Articles 86 and 59 thereof, for a body such as Deutsche Post to exercise the right provided for by Article 25(3) of the UPC, in the version adopted on 14 December 1989, to charge, in the cases referred to in the second sentence of Article 25(1) and Article 25(2) thereof, internal postage on items of mail posted in large quantities with the postal services of a Member State other than the Member State to which that body belongs. On the other hand, the exercise of such a right is contrary to Article 90(1) of the Treaty, read in conjunction with Article 86 thereof, in so far as the result is that such a body may demand the entire internal postage applicable in the Member State to which it belongs without deducting the terminal dues corresponding to those items of mail paid by the abovementioned postal services."
(Emphasis added)
"142. … the Court of First Instance noted the settled case-law, according to which an undertaking abuses its dominant position where it charges for its services fees which are disproportionate to the economic value of the service provided (see, inter alia, Case 226/84 British Leyland v Commission [1986] ECR 3263, EU:C:1986:421, paragraph 27, and Case C-340/99 TNT Traco [2001] ECR I-4109, paragraph 46).
143. As the Court of First Instance held at paragraph 164 of the judgment under appeal, …, the conduct of DSD which is objected to … which consists in requiring payment of a fee for all packaging bearing the DGP logo and put into circulation in Germany, even where customers of the company show that they do not use the DGP system for some or all of that packaging, must be considered to constitute an abuse of a dominant position within the meaning of the provision and the case-law referred to above. …"

The data policy refers to a cookie policy which explains that Facebook places site-related pieces of text information (cookies) on the user's device that enable Facebook to collect information generated from the user's visits on Facebook pages or web pages of companies that use Facebook Business Tools. This happens without the user having to engage in any action other than visiting those pages.
In consideration of the principles of data protection as laid down in Regulation (EU) 2016/679 (General Data Protection Regulation – GDPR), the Bundeskartellamt sees in Facebook's terms of service and the policies to which they refer and under which Facebook is allowed to collect, use and connect data generated off the Facebook pages a violation of the prohibition of abusive practices under Section 19(1) GWB.
In its decision of 6 February 2019, the Bundeskartellamt essentially prohibited Facebook from using terms of service which make the use of Facebook by private users resident in Germany conditional on the operator of facebook.com being allowed to collect and store personal and device-related data generated from the use of the Facebook services WhatsApp, Instagram, Oculus and Masquerade as well as from visiting third-party web pages via integrated plugins, and to connect these data with the data generated from the use of facebook.com without the users' consent. In addition, it prohibited Facebook from using such data and ordered it to take measures to bring the infringement to an end."
"… an abuse of power cannot be denied on these grounds. The court's reasoning fails to consider the interest of those users that do not want to refrain from using Facebook but find it equally important that the collection and processing of their data is limited to what is necessary for the use and financing of the network. By expanding the typical offer … of a social platform with the "offer of a personalised user experience" that is also based on data generated from off-Facebook user activities, Facebook imposes a service on them they might not want, or in any case for which they are not willing to provide access to personal data they have not provided to Facebook itself. There is no need to establish whether by offering this personalised user experience, Facebook is tying two separate products (the provision of functionalities for the use of its network on the one hand and the provision of services based on data generated off-Facebook on the other) or – which is more likely – simply expanding one service. This service expansion is relevant from an antitrust perspective because it means that private users of the platform can only have access to a service they consider indispensable in conjunction with another service they do not want …. They are not given the choice of whether they want to use the network with a more "personalised experience" that is associated with Facebook's potentially unlimited access to information about their off-Facebook online activities, or whether they only want to consent to a level of personalisation that is based on data they reveal on facebook.com itself."
The Court also held that the fact that the data lacked value in the hands of consumers was irrelevant given that personal data was a right belonging to the consumer (protected under legislation) and was valuable in the hands of Facebook (ibid paragraphs [61ff]).
Sales of tickets by third parties
"71…. If Boundary Fares had been widely available and offered from the Respondents' own outlets, it seems to us well arguable that this would have influenced the behaviour of competing third party sellers, and that customer demand would have led those third parties similarly to make these fares readily available from them.
72. We should add that First MTR and Stagecoach, unlike LSER, expressly did not seek to strike out the claims in respect of third party sellers. Ms Abram for Stagecoach sought to argue that as the class includes eligible customers who purchased from third party sellers, the Applicant's economic evidence should have addressed the way the conduct of the Respondents is likely to have influenced those third parties. As we understood it, that argument was not advanced in support of a strike out/summary judgment application and, in any event, it is misconceived. An applicant for a CPO is not expected as part of the application to put forward its full economic evidence. This point is a matter of likely causation of loss, which will no doubt be explored further if a CPO is granted."
Failure to offer Boundary Fares for all ticket types
"There is simply no reason why LSER ought to be obliged at law, particularly in price-regulated environment, to allow customers to combine one type of discount, given for specific reasons, often for specific journeys/flows and at specific times, with some other discount(s), thereby allowing double discounting."
Conclusion
H. Disposition of the appeals
Note 1 There was some debate during the hearing as to whether the table might overstate the position. Mr Moser QC referred to information in Mr Holt’s expert evidence which was capable of modifying figures in the tables but which, even as modified, still led to the conclusion that in respect of over 90% of in-scope journeys Boundary Fares were not offered or available. The CAT will no doubt obtain the most accurate data at trial.

[Back] Note 3 Applying Mr Moser’s metric of five minutes per class member to the facts of Merricks, where the class exceeds 46m individuals, and where there might be no-loss cases, the time estimate for the trial might, even with vigorous case management, be measured in centuries.

[Back] Note 5 Our endorsement of the approach adopted by the CAT in this case is not to be taken as an indication that it is incumbent upon the CAT in all cases at the certification stage to engage in any form of questioning, or hot tubbing, of experts or that it must allow cross examination by the parties. We are though aware that in other cases the CAT has conducted a form of hot tubbing of experts at the certification stage: see e.g. Consumers Association v Qualcomm Incorporated [2022] CAT 20. Ultimately, this is very much a matter for the case-by-case management discretion of the CAT. [Back] Note 6 We can see that there might be very exceptional exceptions even in this counterfactual. If, in a world where the TVM is programmed to offer the optimal price in the simplest and most automatic way, the consumer still makes a silly error when pressing and entering the options on the screen and as a consequence unwittingly pays a higher price that might not be a failure that can be laid at the door of the TOC. In the counterfactual world however, such errors should be exceedingly rare. [Back] Note 7 See footnote [4] above, Jones (ibid) at pages 320 – 323.
