I OVERVIEW OF RECENT PRIVATE ANTITRUST LITIGATION ACTIVITY
Private antitrust litigation in England and Wales continued to grow in 2019, with a number of significant new claims being brought, and a number of important judgments. The year 2019 could also be characterised as something of a waiting period. The parties to a number of proceedings have been waiting for the Supreme Court to hear two important appeals in relation to different aspects of claims, both arising from the credit card interchange fee litigation: in the claims brought by major retailers on the subject of infringement and quantum, and in the collective consumer claims on the subject of the correct approach to the certification of a collective action. The antitrust community generally has also been waiting for developments in the Brexit saga, to learn what is to be the future relationship between EU and UK antitrust law and litigation. We expect 2020 to provide greater clarity on all of these questions.
A key development in 2019 was the judgment of the Court of Appeal in BritNed v. ABB.2 This followed the 2018 judgments in the High Court, in the first case to result in an award of competition damages.3
BritNed claimed around €180 million in damages for losses suffered by its interconnector cable project, a 1,000MW undersea electricity cable connecting the GB and Dutch systems. BritNed procured the cable element of the interconnector from ABB. In April 2014, the European Commission issued a decision in the Power Cables case, fining international manufacturers of high-voltage power cables €302 million for taking part in a cartel that shared markets and allocated customers between them from 1999 to 2009. ABB was the successful immunity applicant, and did not appeal against the Commission's decision.
The judge at first instance awarded damages on two heads. Firstly, he concluded that the effect of the cartel was to insulate ABB from inefficiencies in its own product. Had there been a properly competitive environment, ABB would have faced technical solutions from others involving less copper and perhaps less insulation. This 'baked-in inefficiency' resulted in an overcharge, corresponding to the cost of the additional copper that ABB would have absorbed to retain the bid. The appropriate measure of this overcharge was 15 per cent of the cost of the copper. This amounted to some €7.5 million. Secondly, the judge found an overcharge in the form of a saving in ABB's costs resulting from the cartel, amounting to a further €5.5 million. The judge later reduced the total figure to €11.7 million, reflecting the risk of overcompensation due to BritNed's regulatory arrangements.
The judge rejected BritNed's claim for compound interest, on the basis that higher funding costs had been incurred by BritNed's parents rather than by BritNed itself. However, he awarded simple interest to BritNed.
Both parties appealed to the Court of Appeal, which gave its judgment on 31 October 2019. The Court allowed ABB's cross-appeal in relation to cartel savings, finding that the High Court had made an error of law and that BritNed's damages award should be reduced. The Court emphasised that damages should be based on BritNed's actual loss, rather than on ABB's savings. The Court emphasised that '[t]here is nothing in the EU jurisprudence which suggests that damages in a follow-on case should be other than compensatory.' The Court also dismissed BritNed's appeal, upholding the 'broad brush' approach to calculating damages used by the judge. The Court of Appeal also noted that the presumption of harm contained in the Competition Damages Directive provided no assistance in this case – first because the claim predated the entry into force of the Directive and second because it was 'hard to see how such a presumption could have assisted BritNed, given the need for its loss to be quantified and the generous approach adopted by English law to difficulties of proof'. The Court also refused BritNed permission to appeal to the Supreme Court.
The judgment of the Court of Appeal is significant as the BritNed judgment in the High Court was the first time that a cartel follow-on damages claim had gone to trial on the merits, so this was the first appeal. The judgment examines in detail the correct approach for the assessment of cartel damages and usefully refers to relevant EU and UK jurisprudence underpinning principles of competition damages claims. It will no doubt be an important guide for future claims in the English courts. Key conclusions flowing from the judgment include the principle that damages should be compensatory in nature, not punitive, that no lower standard or reversed burden of proof should apply in follow-on damages claims and that a 'broad brush' approach, involving elements of estimation and assumption, should be used when assessing quantum.
In 2019, the Court of Appeal also made an important ruling4 on the subject of collective competition claims, throwing a lifeline to the prospects of this form of action after they were severely damaged by the Competition Appeal Tribunal's (CAT) refusal to issue collective proceedings orders in the first two applications. In July 2017, the CAT in Walter Merricks v. Mastercard5 refused to issue a collective proceedings order (CPO) in a claim involving credit card multilateral interchange fees. The proposed class included all persons who had, between 22 May 1992 and 21 June 2008, bought goods or services from businesses selling in the UK that accepted Mastercard (and who also satisfied a couple of other conditions). The value of the claim was stated to be £14 billion. The CAT had concerns about the breadth of the class: there would be so many variations in the extent of pass-through that it would not be an issue common to all members of the class. The CAT was also concerned about the methodology for calculating the compensation to which each member of the class would be entitled: it would inevitably result in significant under- or overpayment to any given member of the class. The CAT also provided guidance on the proposed funding arrangements.
It refused leave to appeal on the basis that a judgment refusing a collective proceedings order was not a judgment 'as to the award of damages' for the purposes of Section 49(1A)(a) of the Competition Act 1998, which lists those categories of judgment capable of appeal. However, the Court of Appeal held in November 2018 that it was capable of appeal, and issued its judgment on the substance in April 2019.
The Court of Appeal held that the CAT had erred in law by adopting the wrong approach to the assessment of evidence and the strength of the case on pass-on. The Court of Appeal found that class representatives need only demonstrate that the claim has a 'real prospect of success' at the certification stage. The class representative was required simply to establish that the expert methodology was capable of assessing the level of pass-on and that the necessary data for that methodology was likely to or did exist at trial. The Court of Appeal concluded that the CAT had been too vigorous in probing into the detail of the pass-on data at the certification stage and that it had effectively conducted a mini-trial. The Court of Appeal also noted that certification is a continuing process and so a CPO can be varied or revoked at a later stage if there is insufficient data to calculate pass-on.
The Court of Appeal also found the CAT had erred in its approach to distribution. The CAT had refused certification on the basis that the aggregate award must be distributed on a compensatory basis and must reflect the actual loss suffered by individuals. However, the Court of Appeal found that a loss-based method of distribution is not expressly required by the CAT's procedural rules and rather that damages could be awarded in the aggregate by reference to the loss suffered by the whole class, given that the losses suffered by individual members of the class might not be readily calculable (the 'top-down' approach). The Court of Appeal also found that distribution was a matter to be determined by the trial judge.
In July, Mastercard was given permission to appeal to the Supreme Court, which will hear the appeal in May 2020, providing a degree of certainty as to the correct approach to be taken at the certification stage.
The CPO applications in two claims for damages resulting from the trucks cartel are currently adjourned, in respect of the eligibility question, pending the Supreme Court judgment in Merricks, as are other claims in respect of London transport fares. Two further issues arising from the truck cartel claims, the question of whether the funding arrangements are unlawful 'damages based agreements' and the question of the adequacy of the funding arrangements, were the subject of a judgment of the CAT in October 2019. The CAT concluded that the claimants' litigation funding agreements were not damages-based agreements (DBAs) pursuant to Section 58AA Courts and Legal Services Act 1990 and therefore not subject to the requirements of the DBA Regulations. The CAT concluded that, following further amendments to the agreements between the parties, the funding arrangements did not prevent either of the two class representatives from being authorised as a class representative and acting in the interest of the class members. The CAT was satisfied that the litigation funders had taken responsibility for compliance with the ALF Code. The CAT refused the truck manufacturers permission to appeal on the DBA issue.
ii GENERAL INTRODUCTION TO THE LEGISLATIVE FRAMEWORK FOR PRIVATE ANTITRUST ENFORCEMENT
It has long been accepted that those who have suffered loss as a result of competition law infringements are entitled to claim damages. The House of Lords acknowledged the possibility of damages for breaches of competition law in 1984 in Garden Cottage Foods v. Milk Marketing Board.6 In 2002, the Enterprise Act 2002 inserted Section 47A into the Competition Act 1998, giving the CAT (a specialist competition tribunal that already heard appeals against decisions of the competition authorities) the power to hear follow-on damages claims based on infringement decisions of the European Commission and the UK competition authorities. Section 47B of the Competition Act 1998 also provided for limited opt-in collective claims brought by certain designated representative bodies on behalf of consumers. A number of claims under Section 47A followed. However, this procedure had a relatively low level of uptake because of deficiencies in the drafting of the legislation and rules that limited the scope of Section 47A to strict follow-on claims, and that created very restrictive limitation rules. Claims were constrained by the 'clearly identifiable findings of infringement' in the underlying decision of the competition authority and could not be based on any sort of inference from a decision.
As claimants often wish to claim that an infringement went on for longer, or was wider in scope, than expressly found in an infringement decision, this was a significant restriction of the usefulness of the CAT. The Court of Appeal also held that claimants could not bring proceedings against defendants that were not specifically named as addressees of a decision, which presented a further obstacle to claims as it is often useful to be able to claim against other members of corporate groups in order to anchor jurisdiction in the UK.7 Claimants at that time had a period of two years after the end of appeal proceedings in respect of the underlying decision, or after the date on which the cause of action accrued, if later, in which to bring their claims.
Meanwhile, the High Court had become one of the most popular forums in Europe for competition damages claims following cartel decisions of the European Commission. Claims in the High Court are brought under the common law jurisdiction of the Court, generally as claims for breach of statutory duty.8 They were subject to the standard six-year limitation period under the Limitation Act 1980. However, the Claims in respect of Loss or Damage arising from Competition Infringements (Competition Act 1998 and Other Enactments (Amendment)) Regulations 2017 have now implemented the relevant provisions of the Competition Damages Directive. They inserted Section 47F into the Competition Act 1998, which in turn introduced a new Schedule 8A to the Act. Paragraphs 17 to 26 of Schedule 8A set out the new rules on limitation periods. They differ in a number of important respects from the general rule in England and Wales, set out in the Limitation Act 1980. The general rule under the Limitation Act 1980 is that the limitation period starts when the cause of action accrued. However, where the defendant deliberately concealed from the claimant any fact relevant to the claimant's right of action, the limitation period does not start to run until the claimant has discovered the concealment or could with reasonable diligence have discovered it. For competition claims, while Paragraph 19 introduces rules that are very similar to those set out in the Directive (under which time does not start to run until the claimant first knew or could have known of certain specified facts relating to the infringement), it also introduces the other key requirement of the Directive: namely, that the limitation period does not start until the infringement has ceased. In its judgment in Arcadia v. Visa9 in 2015, the Court of Appeal held that a claim by retailers in respect of losses resulting from credit card interchange fees was out of time in respect of losses suffered before 2007 (six years before the date of the claim) because sufficient facts to allow the claimants to plead their claim were available to them before that date. The Court of Appeal concluded that the Directive did not have retrospective effect, but it appears that had it done so, the entirety of the claim might still have been in time (because the infringement continued until less than six years before the date on which the proceedings were started). As such, Paragraph 19(1)(a) has potentially far-reaching effects. Paragraphs 20 to 25 set out a number of situations in which the limitation period is suspended, including while an investigation by a competition authority is ongoing, while a consensual dispute resolution process is in progress and while collective proceedings are pending.
In 2015, the provisions of Chapter 2 of Part 3 of the Consumer Rights Act 2015 entered into force. They amended Sections 47A and 47B, and introduced Sections 47C to 47E and 49A to 49E, of the Competition Act 1998. They introduced a number of refinements to proceedings before the CAT. First, Section 47A extended the jurisdiction of the CAT to permit stand-alone as well as follow-on claims, addressing one of the key concerns about the previous arrangements. However, Section 47A provided only a partial fix, because there remains some doubt as to whether it provides for stand-alone claims for infringements occurring before 1 October 2015. Secondly, Section 47E aligned limitation periods in the CAT with those in the High Court. Thirdly, Section 15A of the Enterprise Act 2002 provided for fast-track competition claims where one of the parties is a small or medium-sized business and the claim is relatively straightforward.10 Fourthly, Section 47B introduced collective competition damages claims. These were intended to resolve the obstacles faced by small claimants bringing claims individually. Section 47B introduced the possibility of both opt-out and opt-in collective proceedings (where all those falling within an identified class of potential claimants are included in the claim unless they opt out, or where the claim is brought on behalf only of those claimants who have expressly chosen to participate, respectively). In both cases, the claim is brought on behalf of the claimants by a representative.
The CAT must certify a collective claim before it proceeds. The certification process considers the suitability of the class representative who brings the claim on behalf of the class. The CAT Rules set out a number of factors that the CAT must take into account in assessing the suitability of the representative, including whether he or she will act adequately and fairly in the interests of the class, and whether there is a conflict of interest. In practice, the CAT has also considered the level of remuneration of the representative, and the arrangements with the funders.11
The CAT must also consider whether the claims 'raise the same, similar or related issues of fact or law and are suitable to be brought in collective proceedings' (Section 47B(6) Competition Act 1998). This is the central issue in the ongoing Merricks v. Mastercard proceedings, now on appeal to the Supreme Court following the overturning by the Court of Appeal in 2019 of the CAT's refusal to issue a collective proceedings order.
Conduct and agreements that affect trade within the UK, or that affect trade between EU Member States, are capable of infringing the UK and EU competition rules, respectively,12 wherever the undertakings engaging in the conduct or entering into the agreements are located.
In practice, one of the key battlegrounds in private enforcement in the English courts has been the extent to which foreign defendants can be sued in the English courts for losses resulting from international cartels. This issue remained the subject of litigation before the English courts in 2018, addressed both in the judgment of the Court of Appeal in iiyama (see Section I), on the subject of the circumstances in which purchases of cartelised products outside the EU can be said to fall within the scope of Article 101 of the Treaty on the Functioning of the European Union (TFEU), and in Vattenfall v. Prysmian.13 In the latter, the High Court rejected an application to strike out another claim following the Commission's High-Voltage Cable cartel decision, on the basis that there was a realistic prospect that the UK anchor defendants had knowingly implemented the cartel through sales of the cartelised products and the provision of support in respect of the sale of cartelised products. The judgment usefully develops the principles established some years previously in Cooper Tire and Rubber v. Dow and others14 and KME Yorkshire and others v. Toshiba Carrier and others.15
Any person suffering loss as a result of an infringement of competition law has standing to bring a claim.16 It was clear even before implementation of the EU Competition Damages Directive that, subject to issues of causation, pass-through, etc., both direct and indirect purchasers from infringing parties could claim damages for their loss resulting from an infringement. This is now confirmed in the UK rules implementing the Directive, which set out the treatment of pass-through in the case of both direct and indirect purchasers. In accordance with the Kone judgment of the European Court of Justice,17 a number of proceedings in the English courts have included claims for umbrella losses: overcharges resulting from non-members of a cartel increasing their prices in line with the 'market' price set by cartel members. Class representatives in collective proceedings, once certified by a collective proceedings order, have standing to claim on behalf of all members of the class even if they do not themselves fall within the class.
v tHE PROCESS OF DISCOVERY
The introduction, in Article 5, of a requirement for disclosure of relevant evidence was an important and novel aspect of the Competition Damages Directive in most EU Member States. However, disclosure in English court proceedings is well-established and extensive (and has historically been one of the main attractions of the English courts in competition damages proceedings), going some way towards addressing the information asymmetry that claimants commonly encounter. Schedule 8A of the Competition Act 1998, which implements the Directive in English law, therefore introduced no additional disclosure requirements, as the implementing rules did in most other Member States. Instead, it is concerned chiefly with setting out the exceptions to disclosure, reflecting the requirements of Articles 6 and 7 of the Directive, in the case of leniency and settlement materials, and other materials generated during the course of an investigation by competition authorities. These rules are set out in Paragraphs 27 to 35 of Schedule 8A.
The basic principle in English litigation is that each party must carry out a reasonable search for material currently or previously under its control that supports or is adverse to its case. It must disclose those documents by exchange of lists to the other party and then, subject to exceptions for privilege, must provide copies of those documents and allow the other party to inspect any original documents.18 In follow-on private competition claims in the English courts it is very common for the parties to seek disclosure of specific categories of documents, for example documents provided to competition authorities, at an earlier stage than would usually be the case. The judgment in National Grid v. ABB19 provides a good example of this. There is also scope for the parties to request further information from each other in relation to issues set out in their pleadings. In addition, it is possible, subject to certain conditions, to obtain disclosure from third parties. The parties will also have to exchange detailed witness statements setting out the evidence that their witnesses will rely on at trial and upon which they will be cross-examined. There is no deposition process pretrial in English proceedings.
vi USE OF EXPERTS
The use of expert economic evidence is almost universal in private competition enforcement proceedings. Other experts are also often brought in, particularly in abuse of dominance cases, to testify as to the operation of a particular market or other technical issues.20
Although expert economists generally submit their reports when the proceedings are well advanced, it is common to involve them from the outset to provide initial advice on the scope and shape of a claim. Expert economists have also appeared in the collective proceedings order hearings giving evidence as to whether there are sufficient common issues as between the members of the class of prospective claimants to justify certifying the collective proceedings.
While the standard arrangement is for each party to call its own expert witnesses separately, for them to be cross-examined by the other party's counsel, competition damages claims in the English courts are starting to see the emergence of hot-tub arrangements, in which each party's economists appear concurrently and are then questioned by both sets of counsel and by the judge, allowing their evidence to be more easily compared and tested.21 The court's assessment of the parties' expert evidence was central to the outcome of the BritNed v. ABB claim, described in Section 1.
vii CLASS ACTIONS
As explained in Sections I and II, collective proceedings for competition damages claims may be brought before the CAT. Collective proceedings are subject to certification by the CAT. If properly formulated, collective proceedings allow a much wider range of victims of anticompetitive activity to claim damages for their loss. Bringing individual claims would simply not be feasible for the value of loss typically suffered by an individual consumer. It is clear that there is a tension between increasing the efficiency of collective proceedings by framing a class as widely as possible, thereby increasing the number of members of the class, and ensuring that the class is not so wide that the issues in the claims are no longer common to all of the members of the prospective class. This tension should be relieved, at least in part, by the forthcoming judgment of the Supreme Court in Merricks v. Mastercard, referred to in Section I above. There are a number of other mechanisms for class actions available in the courts of England and Wales, including group litigation orders (GLOs) and representative actions (which are comparatively rarer than GLOs).
viii CALCULATING DAMAGES
Damages in private competition claims are intended to compensate for the loss resulting from an infringement of competition law. Nearly all competition damages claims to date have settled, with little or no visibility of the basis or extent of any damages agreed. However, the calculation of competition damages will typically involve an assessment of the counterfactual or 'but for' position: that is, what prices would have prevailed in the absence of the infringement. To assess what would have happened in the absence of a cartel, prices before and after the cartel period, prices of other comparable products, prices of raw materials or components, and the level of profitability of the cartel members will all be taken into account to build up a picture of the but for price. There will also generally be an assessment of the losses resulting from any reduction in sales resulting from increased prices, as well as of the run-off effect of the time taken for prices to return to a non-cartelised level after the end of the cartel. In Sainsbury's v. Mastercard,22 the CAT assessed the overcharge as the difference between the MIFs paid and the bilateral interchange fees that would have been paid in the counterfactual situation. In BritNed v. ABB, the Court of Appeal in 2019 set out important principles about the primarily compensatory nature of competition damages.
There is no provision for multiple damages as seen in the United States, for example. Exemplary or punitive damages are also not available. However, in contrast to the position in the United States, interest on damages runs from the date when the loss was suffered. This may be many years before payment of any damages, and interest can therefore be a very significant component of any award.
ix PASS-ON DEFENCES
There is no pass-on defence in English law. The impact of any pass-on is assessed as part of the assessment of loss generally. The rules implementing the EU Competition Damages Directive set out the treatment of pass-on in claims by both direct and indirect purchasers (see Section I). Paragraphs 8 to 11 implement the provisions of Articles 12 to 15 of the Directive that set out rules relating to overcharges, underpayments and pass-on. They provide that, if the claimant was an indirect purchaser, once it has established that there was an overcharge or underpayment to a direct purchaser, the burden of proof lies on the defendant to prove that it was not passed on to the claimant. They also provide that the burden of proof lies on the defendant to prove that any overcharge or underpayment to the claimant was passed on to the claimant's customers. The English courts have already considered this latter aspect of pass-on,23 but Schedule 8A Competition Act 1998 is useful in its treatment of pass-on to an indirect purchaser claimant.
x FOLLOW-ON LITIGATION
By virtue of the principle first set out in the Masterfoods judgment of the European Court of Justice,24 and then codified in Article 16 of Regulation 1/2003, national courts may not take decisions 'running counter to the decision adopted by the Commission'. They must also 'avoid giving decisions which would conflict with a decision contemplated by the Commission in proceedings it has initiated'. In the English courts, in National Grid v. ABB, for example, this principle was interpreted to mean that while the trial should not be fixed until three months after all appeals by the defendants against the Commission's decision had been determined, the parties should proceed with the exchange of pleadings, disclosure and other preparatory steps. A similar approach has been adopted in other cases since then.
The Competition Damages Directive and the UK implementing rules set out restrictions on the use of evidence developed in the course of European Commission investigations, and on the extent to which immunity recipients and other classes of participant in enforcement proceedings by competition authorities may be liable to pay damages in subsequent private damages claims.
The English courts recognise legal advice privilege, covering advice by lawyers to their clients provided in a relevant legal context, and litigation privilege, covering communications between a client and a lawyer or between either of them and a third party where litigation is underway or reasonably in contemplation, which have been made for the dominant purpose of litigation. In its judgment in SFO v. ENRC25 in September 2018, the Court of Appeal overturned the controversial and narrow approach taken by the High Court regarding the remit of litigation privilege in the context of a contemplated criminal investigation. It declined to rule on the scope of legal advice privilege (and specifically the restrictive rule in Three Rivers (No. 5),26 commenting that it is for the Supreme Court to decide this issue. Further clarification is to be hoped for; meanwhile, care should be taken in this area.
English law does not recognise joint work product defences as such. In some circumstances, two parties may have a joint interest in the subject matter of a privileged communication such that they may share the document without loss of privilege. Similarly, communications that are already subject to legal advice privilege or litigation privilege may in some circumstances be shared with a third party (in the context of private competition enforcement, typically a co-defendant) without automatically losing that privilege where the two parties have a common interest. Again, this is a complex area and specific advice should be sought.
xii SETTLEMENT PROCEDURES
Most competition damages claims before the English courts settle – some at an early stage and some at trial – with the result that there have only been two final judgments awarding damages in competition damages claims to date.27 Settlement is encouraged. Part 9 of Schedule 8A Competition Act 1998 implements the rules in the Competition Damages Directive on settlements, providing for the value of claims to be reduced by a settling infringer's share of the loss. It also prohibits non-settling defendants from seeking a contribution from the settling defendant, so an early settling defendant that settles for less than its share of any overall damages pot cannot then be required to indemnify defendants that settle or are ordered to pay a higher proportion later. This seems likely to incentivise early settlement.
Competition damages claims can be, and are, the subject of arbitration and other forms of alternative dispute resolution. This may in some circumstances be agreed at the time a claim is first contemplated. In Microsoft v. Sony,28 the High Court stayed proceedings because it concluded that the dispute was covered by a pre-existing arbitration clause.
xiv INDEMNIFICATION AND CONTRIBUTION
The general principle is that liability for losses caused by infringement of the competition rules is joint and several, and that defendants may seeks contributions from each other. However, Schedule 8A Competition Act 1998, implementing the EU Competition Damages Directive, sets out rules that limit the liability of certain parties to make contributions.
xv FUTURE DEVELOPMENTS AND OUTLOOK
A key development that is certain to affect competition litigation in the English courts is Brexit. Estimates of its impact vary considerably, and are heavily dependent on the future relationship between the UK and the EU. The advantages of litigating in the English courts are sufficiently significant that claimants and their lawyers are likely to seek to continue to bring their claims in London. What legal routes are available to them will depend on the longer-term trade relationship between the UK and the EU. As things currently stand, the UK is due to leave the EU on 31 January 2020, but there will be a transitional period until 31 December 2020, during which EU law will continue to apply to the UK. For now at least, private enforcement of EU antitrust law in the UK will continue as at present.
