The Private Competition Enforcement Review: European Union

Overview of recent private antitrust litigation activity

In recent years, the private competition litigation landscape in the EU has been shaped by the implementation of the Damages Directive. The Damages Directive was intended to achieve greater harmonisation between private competition enforcement regimes across Member States, in pursuit of the express aim of the European Commission (Commission) to encourage greater private enforcement of competition law. However, while the Damages Directive was successful in prescribing a series of minimum requirements, Member States retain discretion over a range of areas and there remain significant variations between national regimes. In many jurisdictions, the effect of the implementation of the Damages Directive has been to create a unique regime for competition claims that is distinct from general civil litigation claims.

Beyond the Damages Directive, a significant recent EU development in the competition sphere has been an increased focus on harmonisation of the class action regimes across Member States, including the recent legislative activity relating to the draft directive on representative actions.

In terms of competition litigation activity in individual Member States, there has been a significant upward trend across the EU. Of particular note are the follow-on competition claims arising from various Commission decisions that have been litigated (often in parallel) in multiple Member States.

General introduction to the legislative framework for private antitrust enforcement

Articles 101 and 102 of the Treaty on the Functioning of the European Union (TFEU), alongside Regulation 1/2003,2 provide the foundation of the legislative framework for private competition law enforcement: these directly applicable provisions afford EU citizens the substantive right to bring damages claims for harm suffered as a result of a breach of EU competition law.

These legal instruments do not, however, address the procedural elements of private competition law enforcement. Until the introduction of the Damages Directive, there was no single EU legal instrument addressing how competition claims could be brought in practice. As discussed in Section I, the Damages Directive set out to create 'a more level playing field for undertakings operating in the internal market'3 by stipulating the minimum requirements that Member States' national laws must meet.

Despite this, the extent of harmonisation should not be exaggerated. The Damages Directive did not address a number of important practical matters, such as costs and funding, collective redress and injunctive relief. Moreover, for issues such as jurisdiction and governing law, it remains necessary to turn to other pieces of EU legislation (see below). Even where the Damages Directive does address a particular issue, there is scope for divergence in the interpretation (and therefore the implementation) of its provisions. This is apparent in, for example, how certain Member States have chosen to treat the provisions relating to limitation.

The Damages Directive contains a provision setting out the conditions for the temporal application of its procedural and substantive provisions.4 Member States had to ensure that: national measures adopted to comply with substantive provisions did not apply (1) retroactively;5 and (2) to actions for damages of which a national court had taken jurisdiction prior to 26 December 2014.6

i Limitation

The Damages Directive introduced a minimum limitation period of five years for cartel damages claims.7 This five-year period does not begin to run until the infringement ceases and a claimant is aware of (or can reasonably be expected to be aware of) the behaviour constituting the infringement, the fact that the infringement caused him or her harm and the identity of the infringer.8

The Damages Directive also included a provision to suspend the limitation period during an investigation and any subsequent appeal process. This suspension must end no earlier than one year after the infringement decision has 'become final' (the meaning of which is open to some debate).9 The limitation period must also be suspended for the duration of any consensual dispute resolution process.10

These provisions have significantly extended the limitation periods in a number of Member States.11 Pre-implementation, this was an area where there was wide divergence between Member States, both in terms of the length of limitation periods and the point at which they began to run: compare, for example, the UK (six years after the cause of action accrued) with Spain (one year from the date the injured party discovered the harm). This meant that limitation periods often used to play an important role for claimants when selecting the jurisdiction in which to bring a claim.

Nonetheless, some differences between Member States remain. The Damages Directive does not prevent Member States from imposing limitation periods in excess of five years or absolute limitation periods.12

The European Court of Justice (ECJ) has recently considered the scope and effect of limitation provisions in competition claims in Cogeco Communications Inc.13 While the Damages Directive did not apply to the facts at issue, the ECJ held that overly restrictive limitation periods in place before the application of the Damages Directive may be incompatible with EU law.14

ii Jurisdiction

Under EU law, jurisdiction is regulated by the Recast Brussels Regulation,15 which applies to proceedings issued on or after 10 January 2015. Under the Recast Brussels Regulation, the default jurisdiction rule is that a claim should be brought in the courts of a Member State where the defendant is domiciled.16 There are, however, a few exceptions to this rule and two are frequently relied on in the context of competition claims.

First, where there are multiple defendants domiciled in different Member States, a claimant can opt to bring a claim in any of those jurisdictions. A defendant may then become an 'anchor defendant', with others being joined to that claim, provided that the claims are so closely connected that it is expedient to hear them together so as to avoid the risk of irreconcilable judgments resulting from separate proceedings.17

Second, in matters relating to tort, delict and quasi-delict, a claimant can bring a claim in the courts of a Member State which is 'the place where the harmful event occurred or may occur'. In the context of competition claims, the ECJ has confirmed that this means a Member State where the cartel was definitively concluded or a Member State where the claimant company has its registered office.18 Further, in its recent Tibor-Trans judgment,19 the ECJ noted that 'the place where the harmful event occurred or may occur' can also cover the place where a market was affected by a competition law infringement, such as the place where prices were distorted and in which the victim claims to have suffered damage.

In relation to parties' agreements on forum, the ECJ has recently offered some guidance on the enforceability of jurisdiction and arbitration clauses in competition claims. In Apple Sales International,20 the ECJ held that the mere fact that a jurisdiction clause does not explicitly refer to claims based on competition law does not automatically prevent it from applying to actions for damages for abuse of dominance based on Article 102 TFEU. The decision is arguably inconsistent with the ECJ's earlier decision in CDC,21 which held that an explicit reference to claims based on competition law is a prerequisite for applying a jurisdiction agreement to cartel-related claims based on violations of Article 101 TFEU.

iii Governing law

For events that gave rise to damage after 11 January 2009, the governing law applicable to a restriction of competition is determined by the Rome II Regulation.22 Under the Rome II Regulation, the governing law will be the law of the country where the market is affected.23 When the market is affected in multiple countries, a claimant may choose to base its claim on the law of the Member State where it is bringing its claim, as long as the market of that Member State is directly and substantially affected by the restriction of competition that gives rise to the claim.24 This enables claimants to have their case for competition damages heard by one court applying one law, even where more than one defendant is involved or damage occurred in several EU Member States.

Generally, the Rome II Regulation allows parties expressly to agree a law to govern their non-contractual obligations, either before or after the occurrence of an event that gives rise to damage.25 However, in the context of competition claims, such agreements are ineffective insofar as they aim to displace the applicable law determined in accordance with the default rules.26

In recent years, Member State courts have considered the application of choice of law rules under the Rome II Regulation (and the respective national rules pre-dating the Rome II Regulation) in the context of competition law claims.27 This developing jurisprudence may result in a preliminary ruling request to the ECJ.


EU competition law applies to any conduct that has an appreciable effect on trade between Member States. The EU courts and the Commission have long considered to what extent, and in what circumstances, EU competition law can apply extraterritorially (i.e., to non-EU undertakings and to conduct that takes place outside the EU) without infringing the principles of public international law. The two main legal tests that have been developed to limit the extraterritorial reach of EU competition law are the implementation test28 and the qualified effects test.29 The former requires that the practices that restrict competition are implemented in the EU (e.g., by direct sales into the EU). The latter requires that such practices have immediate, substantial and foreseeable effects in the EU. The relationship between the implementation test and the qualified effects test was clarified in Intel,30 where the ECJ observed that the tests pursue the same objective and that EU competition law is applicable if either one is satisfied.

In recent years, Member State courts have started to examine the limits of the extraterritorial application of EU competition law in the context of private enforcement,31 and it remains to be seen whether a consistent approach will be adopted across the EU.


Any individual or undertaking may claim compensation before national courts for harm suffered as a result of an infringement of EU competition law.32 The exercise of the right to sue is governed by national law provisions in the particular jurisdiction in which an action is brought, but the rules and procedures facilitating such actions cannot be less favourable than those governing similar actions resulting from infringements of national law.33

The causal relationship between the harm and the infringement need not be direct; and the Damages Directive explicitly granted indirect purchasers standing to sue.34 A party need not have a contractual link to a cartelist and will have a claim against cartelists where its loss was suffered as a result of the actions of an undertaking not party to the cartel (having regard to the practices of the cartel), namely where that undertaking sets prices higher than would otherwise have been expected under competitive conditions (umbrella pricing).35 In recent years, Member State courts have heard numerous cases involving indirect purchasers.

The process of discovery

The move towards harmonisation of the disclosure regimes across Member States was one of the most significant changes brought about by the implementation of the Damages Directive. Previously, there was a wide disparity between jurisdictions with sophisticated and well-established disclosure regimes (such as the UK), which were considered claimant-friendly, and jurisdictions where extensive disclosure did not feature in civil litigation (notably Germany and the Netherlands, although these nevertheless remained popular jurisdictions for bringing proceedings for other reasons). EU legislators considered the lack of extensive disclosure regimes in such countries to be an obstacle to effective private enforcement of competition law, on the basis that it maintained the information asymmetry that may exist between a party allegedly having suffered loss and an infringer of competition law.

To address this, the Damages Directive required Member States to ensure that national courts are able to order defendants or third parties to disclose relevant evidence that lies within their control in response to a reasoned justification by a claimant.36 Member States must also ensure that national courts are able, on the request of a defendant, to order a claimant or a third party to disclose relevant evidence.37 To address concerns regarding excessive disclosure or fishing expeditions, the Damages Directive stipulated that national courts must be able to limit disclosure to what is proportionate, having regard to the legitimate interests of all parties concerned.38 While Member States must ensure that national courts have the power to order the disclosure of relevant confidential information, national courts must concurrently have at their disposal effective measures to protect such information39 and to give full effect to applicable legal professional privilege rules.40

For legal systems unaccustomed to extensive disclosure exercises, these new rules have started to cause significant cultural change (although a combination of transitional rules41 and the need for national courts to acclimatise means it is likely to be a number of years before the full effects become apparent). In particular, the references in the Damages Directive to disclosure of 'relevant categories of evidence'42 marked a significant change in jurisdictions where disclosure was previously limited to specific documents identified in a disclosure request. However, while there is likely to be some degree of harmonisation between Member States going forward, the Damages Directive only fixed minimum requirements43 and a number of jurisdictions have taken the opportunity to go further by creating a substantive right to disclosure (as opposed to giving national courts mere discretion). It remains to be seen whether these regimes will develop to match the extensive disclosure seen in the UK.

As a further protection against excessive disclosure, the Damages Directive contained a number of limits on the disclosure of evidence included in a competition authority's file. In particular, leniency statements44 and settlement submissions,45 as well as verbatim quotations from such documents,46 were granted absolute protection from disclosure.47 Disclosure of the following materials from a competition authority's file is permissible, but only after the competition authority has closed its proceedings: information prepared specifically for the proceedings of a competition authority; information drawn up by the competition authority and sent to the parties in the course of its proceedings; and settlement submissions that have been withdrawn.48 Even then, national courts should (as part of the proportionality assessment) consider the need to safeguard the effectiveness of public enforcement when choosing whether to order disclosure of such documents.49

The ECJ examined the scope of publication of leniency material in a Commission decision in the Evonik Degussa and AGC Glass Europe cases.50 In Evonik Degussa, the ECJ found that the content of a leniency statement can be referred to in a Commission decision, provided that the source cannot be identified and the precise contents of the submission cannot be reconstructed. These principles were affirmed in AGC Glass Europe. These decisions form part of an ongoing line of cases concerning the confidential nature of materials relating to Commission decisions, which is particularly important in the context of competition claims in national courts.

Use of experts

The Damages Directive is silent on the issue of experts, but the Commission recognises the importance of expert advice in private competition actions and has published, commissioned and contributed to various guidelines for judges and other practitioners on obtaining and assessing expert evidence.51 This is driven in particular by the complexities of quantifying harm, which in practice requires significant data, with both claimants and defendants routinely engaging economic experts to assess the amount of loss suffered.

The use of experts and their role in court proceedings vary among Member States. Rules differ, for example, regarding whether experts should be party-appointed or court-appointed and the weight given to their findings. Dutch, English, French and German courts are willing to deal directly with economic reports prepared by experts appointed by the parties, for example, while judges in certain other jurisdictions tend to rely solely on court-appointed experts when addressing economic questions.

Member States also differ significantly with respect to the partiality of party-appointed experts, and consequently the weight the court places on such expert evidence. For example, in English courts, party-appointed experts owe a duty to the court, while in Germany there is no express requirement towards objectivity and so party-appointed experts are treated as potentially partisan extensions of the party in question.

Experts need not always be economics or accounting professionals. There is a growing trend in competition cases for industry experts to testify, lending their knowledge of the dynamics and operation of certain markets, particularly in cases concerning complex distribution chains. This serves the dual purpose of educating the court on the market in question and ensuring that economists approach the relevant questions using correct assumptions.

Class actions

On the same day that the Commission published its proposal for the draft Damages Directive (11 June 2013), it also published a Recommendation on collective redress mechanisms for breaches of citizens' rights granted under EU law (the Recommendation).52 The Recommendation followed a Green Paper on competition law damages actions published in 200553 and a White Paper published in 2008,54 which included suggestions on competition-specific collective redress mechanisms. Due in part to concerns about the potential for US-style class actions, a consensus was not reached on this subject and no provision for collective redress was included in the Damages Directive. Instead, the Commission issued a non-binding Recommendation (and an accompanying Communication)55 to Member States to implement collective mechanisms for violations of EU law rights by 26 July 2015 (concerning both injunctive and compensatory relief). The Recommendation applied not only in the competition sphere, but also in relation to claims for other breaches of citizens' rights under EU law, including consumer protection, environmental protection, protection of personal data, financial services legislation and investor protection.56

The Recommendation provides, among other things, that collective redress should be based on the express consent of the relevant claimants (i.e., the opt-in model) and that any exceptions to this principle (such as opt-out proceedings) should be 'duly justified by reasons of sound administration and justice'.57 The Recommendation also provides that there should be safeguards for minimising the risk of excessive litigation.

The availability of collective redress mechanisms, and safeguards against the abuse of such mechanisms, is not consistent across the EU. On the one hand, some Member States (including Belgium, France, Lithuania and the UK) have actively promoted collective redress since 2013. On the other, there are a number of Member States that do not at present provide for any possibility of collective redress for damages arising from breaches of EU law.58

Future EU intervention to support EU-wide harmonisation in this area is likely. On 18 April 2018, the Commission published a proposal for a directive on representative actions for the protection of the collective interest of consumers (the Draft Representative Actions Directive) as part of the Commission's 'New Deal for Consumers' package.59 On 26 March 2019, the European Parliament approved an amended version of the Draft Representative Actions Directive 60 and on 28 November 2019, the European Council adopted a general approach to the Draft Representative Actions Directive.61 The Draft Representative Actions Directive aims to empower reputable consumer organisations ('qualified entities') to initiate representative actions on behalf of consumers for infringements of EU law. The system is intended to cover claims for both injunctions and compensation. At the time of writing, the Commission, European Parliament and European Council are involved in negotiations over the final text of the Draft Representative Actions Directive.62

Calculating damages

With a view to assisting in relation to the complicated issue of quantification, in 2013 the Commission published a Communication on quantifying harm in competition law damages actions,63 together with a more detailed Practical Guide,64 to provide national courts and parties to damages actions with an overview of the main economic methods and empirical insights available. The Practical Guide covers various techniques for estimating prices in a counterfactual non-infringement scenario, including observation of comparator data, interpolation and regression analysis.

While the right to compensation is an EU right, the actual methodology for quantifying damages is largely a matter for national law. However, the following broad principles have been established at an EU level under the Damages Directive:

  1. There must be a rebuttable presumption that cartels cause harm. This presumption was deemed necessary because the inherently secret nature of cartels may create an information asymmetry between parties that makes it more difficult for claimants to obtain the evidence necessary to prove the harm.65
  2. Compensation must place claimants in the position in which they would have been had the infringement of EU competition law not been committed. Compensation must therefore cover actual loss, loss of profit and interest, and should not result in overcompensation, whether by means of punitive, multiple or other damages.66
  3. National courts are entitled to estimate the amount of harm a claimant has suffered if it is impossible or excessively difficult to quantify that harm on the basis of the evidence available.67
  4. Member States must nonetheless ensure that neither the burden nor the standard of proof required for the quantification of harm renders the exercise of the right to damages practically impossible or excessively difficult.68
  5. Where requested, and if they deem it appropriate, national competition authorities (NCAs) may provide guidance to national courts on the determination of the quantum of damages.69

Pass-on defences

Member States are required under the Damages Directive to ensure the availability of the passing-on defence. This means that any defendant may invoke as a defence that the claimant passed on the whole or part of the overcharge resulting from the infringement. The burden of proof that any overcharge was passed on falls to the defendant, who may in turn reasonably require disclosure from the claimant or from third parties.70

The Damages Directive also addressed the position of indirect purchasers, making it easier to claim damages incurred as a result of any overcharge that was passed on down the supply chain. Although the burden lies with the indirect purchaser to prove the existence and extent of any pass-on, there is a rebuttable presumption that this burden is satisfied if the indirect purchaser can establish that: the defendant has committed an infringement of competition law (which is automatically the case in any follow-on action); the infringement of competition law has resulted in an overcharge for the direct purchaser of the defendant; and the indirect purchaser has purchased the goods or services that were the subject of the infringement, or has purchased goods or services derived from or containing them.71

The passing-on defence was already recognised in many Member States prior to implementation of the Damages Directive, but some changes to national legislation have been required, for example, to transfer the burden of proof from the claimant to the defendant (as in France) or to introduce a presumption in favour of indirect purchasers (as in Hungary and the Netherlands).

On 9 August 2019, the Commission published guidelines designed to assist national courts in estimating the passing-on of overcharges.72 The guidelines set out the applicable legal framework and discuss the economics of pass-on (including the economic theory and quantification methods).

Follow-on litigation

The Damages Directive was intended to facilitate greater follow-on litigation in the Member States, as well as to ensure the optimal interaction between private and public enforcement.

To this end, the Damages Directive provided that a final decision by a Member State's NCA (or review court) finding an infringement irrefutably establishes that infringement for the purposes of follow-on litigation in the courts of that Member State.73 An equivalent EU-level provision, preventing national courts from taking a contrary view to the Commission where the Commission has found an infringement, has been in place for some time.74

The Damages Directive further provided that a final decision in another Member State must be taken at least as prima facie evidence by a court that an infringement occurred.75 It is noteworthy that some Member States have already gone further in this regard, with German law providing that a final decision by any Member State's NCA will be treated as binding proof of an infringement before the German courts. Implementation has differed significantly across other Member States ranging from Austria (which has followed Germany's approach) to Hungary (which has taken a more restrictive approach by implementing a rebuttable presumption of an infringement in this situation). Regardless of these discrepancies, the overall effect should be to reduce the base evidentiary hurdle to establishing a breach of competition law for follow-on claimants in the EU.

As explained above, the Damages Directive also introduced changes to other key issues that affect follow-on damages, such as limitation and disclosure. The net effect has been to increase venue choice for claimants, with many jurisdictions where the private enforcement regimes were arguably underdeveloped now adopting broadly similar rules.


The Damages Directive stipulates that Member States must ensure that national courts give full effect to applicable legal professional privilege under EU or national law when ordering the disclosure of evidence.76 It is otherwise silent on the issue of privilege. There is no requirement to apply EU privilege laws,77 meaning that the privilege regimes of individual Member States will be applicable to damages proceedings brought in national courts.

The rules protecting communications between a lawyer and his or her client vary considerably between Member States. Broadly, a distinction can be drawn between common law and civil law jurisdictions, with the scope of privilege generally more extensive in the former.78 This stems from the fact that disclosure obligations in civil law jurisdictions were typically (prior to the implementation of the Damages Directive) much narrower than they were under common law.79 This reduced the need for the protection of sensitive legal advice in such jurisdictions. Overlaying this broad distinction is a patchwork of different specific rules. For example, German law has a limited concept of legal privilege. In Ireland, the UK, Poland, the Netherlands and Portugal, legal privilege is recognised for in-house counsel as well as external counsel. In the Netherlands and the UK, privilege is extended to communications with lawyers qualified outside the EEA.

It will be interesting to observe whether Member States with narrower concepts of legal privilege adapt their regimes in light of the increased disclosure obligations under the Damages Directive to provide defendants with additional protection.

Settlement procedures

While the Recitals to the Damages Directive emphasise that damages actions represent only one element of an effective private enforcement system (which should also involve consensual dispute resolution),80 the Damages Directive does not mandate any alternative dispute resolution mechanisms. Nor does it regulate settlement procedures generally. However, it did introduce three measures aimed at incentivising the use of consensual dispute resolution mechanisms and increasing their effectiveness.

First, as noted above, to provide both sides with an opportunity to engage in settlement discussions before bringing proceedings, limitation periods must be suspended for the duration of a consensual dispute resolution process.81 Likewise, if proceedings have already been issued, national courts may suspend their proceedings for up to two years to enable settlement discussions to take place.82

Secondly, the Damages Directive provided that a competition authority may consider compensation paid as a result of a consensual settlement as a mitigating factor when making its decision in imposing a fine.83

Thirdly, and most significantly, the Damages Directive sought to ensure that an infringing party that pays damages through consensual dispute resolution should not be placed in a worse position in relation to its co-infringers than it would otherwise have been in absent the consensual settlement. This might be the case, for example, if a party, even after a consensual settlement, continued to be fully jointly and severally liable for the harm caused by the infringement, and therefore remains open to contribution proceedings from other co-infringers. To address this, Member States must ensure that, following a consensual settlement, the claimant's claim is reduced by the settling co-infringer's share of the harm84 (which is not necessarily the amount it has actually paid),85 and the claimant can only pursue its remaining claim against non-settling co-infringers.86 Importantly, non-settling co-infringers shall not be permitted to recover contribution for the remaining claim from the settling co-infringer.87 This creates significant incentives for defendants to offer an early settlement.

Further, in addition to a class actions regime (discussed in Section VII), a number of Member States have collective settlement regimes pursuant to which groups of claims can be settled, including on an opt-out basis. For example, in the UK the collective action regime available in the Competition Appeal Tribunal includes an opt-out collective settlement regime. In the Netherlands, the Dutch Act on the Collective Settlement of Mass Claims similarly provides for an opt-out mechanism that facilitates collective settlement through a binding declaration from the Amsterdam Court of Appeal.


Arbitration is listed among the consensual dispute resolution mechanisms that are actively promoted by the Damages Directive.88 Although the Damages Directive does not prevent claimants from submitting damages claims to arbitration, it is silent on more specific issues such as whether (and how) to include contractual arbitration clauses in respect of competition claims.

Arbitration is still relatively rare as a means of resolving competition disputes in Europe, due in part to an inherent tension between arbitration as a private system of dispute resolution and EU competition law as a public system designed to protect consumer welfare and the integrity of the internal market. There are other more specific obstacles to the widespread adoption of arbitration in this field; for example, competition claims often involve a large number of claimants or defendants, or both, from different levels of the distribution chain, which can be problematic where each party has an independent contract with its own arbitration clause (or lack thereof).

On the other hand, both arbitration and competition law claims invariably arise in an international context, and arbitral tribunals are accustomed to complex, multiparty cases. A recent decision by the English High Court89 to stay court proceedings so as to give effect to an arbitration clause indicates that competition arbitration may be becoming increasingly accepted in the sphere of private enforcement.

Indemnification and contribution

The Damages Directive required Member States to ensure that cartelists are jointly and severally liable for the full harm caused by the infringement to which they are a party and that the claimant has the right to full compensation from each of the infringers.90 However, in relation to immunity applicants, it provided that they should only be jointly and severally liable to their own direct and indirect purchasers, and should only be liable to other injured parties where full compensation cannot be obtained from the other infringers.91

The Damages Directive further provided that Member States must ensure that any individual infringer can recover a contribution from co-infringers, in accordance with the relative responsibility for the harm of each co-infringer.92 Again, a carve-out is in place to ensure that immunity applicants can only be required to contribute an amount up to the harm caused to their own direct and indirect purchasers.93 The Damages Directive did not define what is meant by relative responsibility for harm and this is left for Member States to decide.94 Notably, the Damages Directive did not specify a limitation period for contribution claims, meaning that this too will be a matter to be decided at a national level.

As long as they have not led an infringement,95 coerced other undertakings to participate in an infringement or previously been found to infringe competition law,96 small and medium-sized enterprises (SMEs) also gained protection from joint and several liability.97 Absent these circumstances, SMEs are liable only to their own direct and indirect purchasers, provided that their market share was below 5 per cent at some point during the infringement and that applying normal joint and several liability rules would irretrievably jeopardise their economic viability.98

These changes represent a novel development for many jurisdictions, including the UK, France, Germany and the Netherlands, and could complicate the recovery process for contribution claimants.

Future developments and outlook

The UK formally ceased to be a Member State of the EU on 31 January 2020. Attention now turns to the negotiation of a new relationship between the UK and the EU. Up to this point, the UK has been one of the most important jurisdictions within Europe for private enforcement actions and claimant firms have expressed confidence that it will remain so. The UK's ongoing status as a centre for private competition law enforcement will to a significant extent depend, however, on whether claimants will be able to continue to rely on infringement decisions issued by the Commission as a basis for founding a follow-on claim in the UK courts.

The terms of the withdrawal agreement provide that the whole body of EU law will (in effect) continue to apply to and in the UK until the end of the transition period (i.e., 31 December 2020, unless extended pursuant to the agreement). Accordingly, the Commission will maintain jurisdiction over investigations initiated before the end of that period and claimants will be able to rely on EU law (and the relevant Commission decisions) to initiate private competition law proceedings before the UK courts. At present, a continuation of this arrangement appears unlikely, but the nature and extent of future co-operation remains unclear. Practically, however, it is likely that claimants would still be able to initiate claims based on breaches of EU competition law (and rely on the relevant Commission decisions) if these claims are framed as foreign tort claims.

More generally in relation to EU law, it is only over the next few years that the full effect of the Damages Directive will become clear. It seems likely at this stage that its major impact will be to increase venue choice for claimants, as jurisdictions that might not previously have been considered become more appealing to claimants.

Another area of interest is the work that the EU is doing in relation to class actions, particularly in relation to the Draft Representative Actions Directive, discussed in Section VII above.

Finally, the upward trend in private competition law activity across the EU is likely to continue and may even be further bolstered by the increased availability of direct litigation funding (including from non-traditional sources, such as private equity houses). These higher levels of activity should in turn lead to further clarification of the relevant law at both the EU and Member State levels.

3 Recital 9, Damages Directive.

4 Article 22, Damages Directive.

5 Article 22(1), Damages Directive.

6 Article 22(2), Damages Directive.

7 Article 10(3), Damages Directive. The limitation period in a number of jurisdictions (e.g., the UK and the Netherlands) already met this requirement, while in others (e.g., Germany and Spain), it was extended by the national implementing legislation.

8 Article 10(2), Damages Directive.

9 Article 10(4), Damages Directive. There has been some criticism, for example by the City of London Law Society in its response to the UK government's consultation on the national legislation implementing the Damages Directive, that Article 10(4) is not clear as to whether an appeal on penalty alone will suspend the limitation period, and whether an appeal by one addressee suspends the limitation period for all addressees. Such questions were previously addressed by the English courts in relation to the former limitation provisions in the cases of BCL Old Co v. BASF [2009] EWCA Civ 434 and Deutsche Bahn AG v. Morgan Advanced Materials plc [2014] UKSC 24. At an EU level, these ambiguities could result in a preliminary ruling request to the European Court of Justice.

10 Article 18(1), Damages Directive. Recital 48 states that 'consensual dispute resolution mechanisms' will include out-of-court settlements, arbitration, mediation and conciliation.

11 By way of example, consider a scenario in which the Commission opened an investigation in 2018 in respect of behaviour that took place between 2010 and 2016, and reached an infringement decision in 2021, with an appeals process lasting until 2024. In this case, the limitation period would only begin to run in 2025, and would last a minimum of five years, until 2030. Therefore, the company would be at risk of a damages claim for almost 15 years after it ceased its anticompetitive conduct.

12 The Damages Directive does allow for long-stop dates to be put in place. Recital 36 states that 'Member States should be able to maintain or introduce absolute limitation periods that are of general application, provided that the duration of such absolute limitation periods does not render practically impossible or excessively difficult the exercise of the right to full compensation'. For example, in the Netherlands, a 20-year long-stop limitation period will apply, starting on the date on which the damage was inflicted, irrespective of the victim's awareness.

13 Case C-637/17, Cogeco Communications Inc v. Sport TV Portugal and Others (2019).

14 On the facts, the ECJ considered the legality of a Portuguese three-year limitation period that commenced on the date on which the claimant became aware of its right to compensation, irrespective of whether the claimant was aware of the identity of the defendant(s) or the full extent of its loss. The ECJ held that this limitation period was incompatible with Article 102 of the TFEU and the EU law principle of effectiveness.
