I OVERVIEW OF RECENT PRIVATE ANTITRUST LITIGATION ACTIVITY

Nearly every year over the past decade, the US Supreme Court has significantly changed the private antitrust litigation landscape. Starting with the establishment of a heightened 'plausibility' pleading standard that governs whether a complaint survives a motion to dismiss,2 subsequent decisions have clarified that:

  1. conduct must be directly linked to cognisable harm or injury to give rise to an antitrust claim;3
  2. activities inextricably intertwined with US Securities and Exchange Commission regulatory activity are immune from antitrust attack;4
  3. plaintiffs bringing antitrust actions under state law in federal court may pursue class actions or class-action remedies not otherwise available in state court;5
  4. a federal court's denial of class certification for a proposed class does not preclude a state court from later adjudicating another plaintiff's proposed class;6
  5. arbitrators may not impose class arbitration on parties unless it is contractually permissible;7
  6. express arbitration clauses trump class-action rights, even in antitrust cases;8
  7. expert testimony does not overcome lack of commonality in class actions;9
  8. class certification requires that plaintiffs establish that damage can be proven with class-wide evidence to satisfy Federal Rule of Civil Procedure (FRCP) 23(b)(3)'s predominance requirement;10
  9. individual corporate entities that are part of a joint venture may be subject to antitrust 'rule-of-reason' scrutiny;11
  10. an order disposing of one discrete case consolidated in a multi-district litigation under 28 USC Section 1407 is an appealable final decision under 28 USC Section 1291;12
  11. stare decisis may have less than 'usual force in cases involving the Sherman Act'13
  12. courts must include both sides of a two-sided credit-card market (merchants and cardholders) in defining a relevant market and evaluating anticompetitive effects;14
  13. that US federal courts are not bound to defer to a foreign governments' official interpretation of its own laws, but owe the foreign government's interpretation 'respectful consideration';15 and
  14. that the Supreme Court's ruling in Illinois Brick Co v. Illinois, which bars antitrust suits by indirect purchasers, did not apply to consumers who purchased apps from Apple's App Store, even though Apple only collected a commission on the apps and did not set their prices.16

The lower federal courts apply these Supreme Court cases, deciding issues related to antitrust injury, standing requirements, the statute of limitations, class actions, discovery and pleading standards.

II GENERAL INTRODUCTION TO THE LEGISLATIVE FRAMEWORK FOR PRIVATE ANTITRUST ENFORCEMENT

Private plaintiffs may bring suit in federal court for violations of federal antitrust law under two provisions of the Clayton Act of 1914. Section 4 allows private plaintiffs to sue for money damages, including reasonable attorneys' fees as well as prejudgment interest on actual damages at a court's discretion if such an award is 'just' under the circumstances.17 Section 16 allows private plaintiffs to sue for injunctive relief.18

i Statute of limitations limits the period of potential recovery

A four-year statute of limitations applies to Section 4 claims.19 The limitations period commences when the cause of action accrues, which generally occurs when the plaintiff suffers injury and damages become ascertainable.20 Section 16 claims may also be subject to a four-year statute of limitations. Some courts have held that the four-year limitation period also applies to Section 16 claims, while others have held that it does not.21 The defence of laches nevertheless bars Section 16 claims four years after accrual of the cause of action, unless the court finds equitable reasons to allow the claim.22

The statute of limitations may be tolled by government antitrust actions,23 the filing of a class action,24 fraudulent concealment,25 duress26 or equitable estoppel.27 Where a series of overt acts rather than one definitive act causes new injury to plaintiffs, the 'continuing violation' doctrine restarts the statute of limitations period.28 Some courts allow the tacking of tolling periods.29

ii State antitrust claims

Most US states and territories have adopted antitrust statutes. They generally mirror the federal scheme, and prohibit monopolies and unreasonable agreements (like the Sherman and Clayton Acts) and unfair and deceptive trade practices (like the Federal Trade Commission (FTC) Act). The vast majority provide for private rights of action. Statute of limitations periods vary by state.

The statutes and courts' interpretations of them differ on various points, such as the availability of treble damages,30 restitution, class actions and availability of recovery for indirect purchasers.

III EXTRATERRITORIALITY

i General jurisdictional rule

The Foreign Trade Antitrust Improvements Act of 1982 (FTAIA) limits the extraterritorial reach of the Sherman Act to foreign anticompetitive conduct that either involves US import commerce or has a 'direct, substantial, and reasonably foreseeable effect' on US import or domestic commerce.31 Courts have construed this to require a 'reasonably proximate causal nexus' between the conduct and the effect on US commerce or import commerce, a standard similar to a proximate causation standard.32 Additionally, a plaintiff's injury must occur in the US rather than a foreign market to 'give rise to' a claim under the Sherman Act.33 Although the US effects requirement is sometimes characterised as a jurisdictional issue, it has been treated as a substantive element of the Sherman Act.34

When a plaintiff alleges other antitrust claims, such as under the Clayton Act, the extraterritoriality test applies,35 subject to territorial limitations found in the substantive provision asserted. For example, Section 3 of the Clayton Act only reaches transactions in which the products are sold for use, consumption or resale in the US.36 Additionally, the FTAIA extends the Sherman Act's extraterritoriality test to apply to the FTC Act.37

A circuit split has arisen as to whether the FTAIA bars Sherman Act claims arising out of foreign conduct of a cartel. While the Seventh Circuit interpreted the FTAIA as barring the Sherman Act claims,38 the Ninth Circuit held that the conduct of the same cartel was within the reach of the Sherman Act.39 The US Supreme Court recently denied a petition for certiorari to resolve this issue, so lower courts will continue to develop the law to clarify how these decisions apply.

ii Comity considerations

A court may employ comity considerations to decline jurisdiction, even when the FTAIA's requirements have been satisfied.40 Comity considerations generally come into play when domestic and foreign law are in conflict, such as where one law requires a defendant to engage in acts prohibited by other laws.41

iii Exemptions

Foreign sovereigns are presumptively immune from US courts' jurisdiction under the Foreign Sovereign Immunities Act (FSIA).42 To rebut the presumption, a plaintiff must show that one of the FSIA's seven exceptions applies.43 The most common exemption in antitrust cases is the commercial activity exception, which precludes FSIA immunity where a foreign sovereign state's commercial activity has a 'nexus' with the US.44 The scope of 'commercial' activity, 'foreign state' and the specific nexus required to meet this exception has been extensively litigated.45

The act-of-state doctrine requires US courts to recognise the validity of public acts performed by authorised agents of foreign sovereign states within their jurisdictions.46 Thus, where a plaintiff's claim depends on the invalidity of a foreign sovereign state's domestic act, the act-of-state doctrine may absolve the defendant of liability. Various exceptions apply, such as where an extant treaty provides applicable legal standards, where the act involves a commercial function or where US foreign policy interests would not be advanced by application of the doctrine.

A private party whose conduct was compelled (and not merely sanctioned or assisted) by a foreign sovereign state will generally be immune from antitrust liability under the assumption that the defendant's activity was effectively foreign sovereign state activity.47 US federal courts must give 'respectful consideration' to a foreign government's official statement on the correct interpretation of its own laws, but are not bound to defer to the foreign government's interpretation.48

IV STANDING

i Standing under Section 4 of the Clayton Act

To maintain a lawsuit under Section 4 of the Clayton Act, an antitrust plaintiff must allege:

  1. that the plaintiff is a 'person' under Section 1 of the Clayton Act;49
  2. that the defendant violated the 'antitrust laws';50
  3. antitrust injury ('impact' or 'fact of damage'),51 that is, harm to competition52 to a plaintiff's 'business or property' proven by direct or circumstantial evidence or inference53 with a reasonable degree of certainty;54 and
  4. that the antitrust violation was a material and substantial cause of the injury.55

Finally, the plaintiff must satisfy the remoteness doctrine, which requires that a plaintiff's injury is not too remote from the defendant's conduct, by addressing five factors: 56

  1. causal connection between the violation and the harm to the plaintiff, and whether defendants intended to cause the harm;
  2. nature of the injury, including whether the plaintiff is a consumer or competitor;
  3. directness of the injury, and how speculative or tenuous the damages are;
  4. potential for duplication of recovery or complex apportionment of damages; and
  5. whether more direct victims exist.

The doctrine generally limits the plaintiff class to consumers and competitors, and denies standing to creditors, employees, officers, shareholders and suppliers of antitrust victims. The remoteness doctrine may bar an indirect purchaser57 from bringing a Section 4 claim unless it is a competitor.58 Some courts require that the plaintiff is an 'efficient enforcer' or a potential competitor sufficiently prepared to enter the market.59

ii Standing under Section 16 of the Clayton Act

A plaintiff who has standing to bring an antitrust action under Section 4 will also have standing under the more lenient requirements of Section 16, which are as follows:60

  1. the plaintiff is a 'person, firm, corporation, or association';61
  2. the defendant violated the 'antitrust laws';62
  3. the threatened loss or damage proximately results from the alleged antitrust violation;63 and
  4. the 'antitrust injury', that is threatened loss or injury, is due to harm to competition.64

However, there are differences. Section 16 requires 'threatened loss or damage'65 that is a 'significant threat of injury from an impending violation of the antitrust laws or from a contemporary violation likely to continue or recur66 rather than actual loss.67 Unlike Section 4 claims, the threatened loss or injury in a Section 16 claim is not limited to injury to business or property.68 Finally, courts do not impose the remoteness doctrine on Section 16 claims, so indirect purchasers may sue for injunctive relief, even though they may not sue for monetary damages.69

iii Indirect purchaser standing

Generally, indirect purchasers who purchase from a defendant indirectly through a downstream distributor cannot recover under federal antitrust laws unless70 the direct purchaser had a pre-existing 'cost-plus' contract, shifting the entire overcharge to the indirect purchaser;71 there is also an ownership-control exception, where the direct purchaser is owned or controlled by the defendant or the indirect purchaser;72 indirect purchasers may also sue where the direct purchaser was a co-conspirator.73 The Supreme Court clarified the scope of the bar on indirect purchaser suits in 2019, ruling that plaintiffs who purchase directly from an alleged antitrust violator have standing to sue even if the defendant only collects a commission and does not set the price of the product sold.74

Indirect purchasers may recover under the Illinois Brick repealer statutes of 26 states as well as state consumer protection statutes.75

V THE PROCESS OF DISCOVERY

The scope of discovery in antitrust cases is broad. FRCP 26 allows discovery of a reasonable time period, geographical scope, and subject matter if the requested information is relevant to any claim or defence, proportional to the needs of the case, and the burden of the proposed discovery on the responding party does not outweigh its benefit. What is relevant for discovery is broader than what is admissible as evidence at trial.

Courts may restrict 'unduly burdensome' discovery requests where the burden and expense outweigh the prospective benefit of the requests.76 FRCP 26(c) allows courts to restrict discovery of confidential business information or trade secrets and privileged attorney–client communications or attorney work product. Grand jury materials are only discoverable if the party has strongly demonstrated a 'particularized need' for the materials.77

In deciding whether to allow discovery from non-party market participants, courts consider the relevance of and need for the information, whether the information is protected as trade secret or confidential commercial information, and whether the request will cause the non-party undue hardship.78 A party that refuses to comply with a court order may face sanctions.79

Courts generally grant requests to compel discovery from domestic or foreign affiliates or subsidiaries of corporations that are parties to the antitrust case.80 Generally, a foreign party subject to personal jurisdiction in the US is subject to discovery.81 Foreign blocking statutes do not allow a corporation present in the US to resist producing documents located abroad.82

VI USE OF EXPERTS

Plaintiffs may use expert testimony to establish various elements of a private antitrust claim. Expert testimony is often key in certifying a class83 on substantive antitrust issues like market or monopoly power, anticompetitive harm, antitrust injury and damages.

Expert testimony is only admissible if 84 the expert has sufficient specialised knowledge and expertise with respect to the field in question; the methodology and data used to reach the expert's conclusions are sufficiently reliable; and the expert's testimony is sufficiently relevant to assist the trier of fact.

Reliability is the most common basis on which expert testimony is excluded. Several factors are considered to determine whether the proffered testimony is reliable, such as whether the expert's methodology has been tested, is subject to peer review or is widely accepted by the relevant scientific community.85

VII CLASS ACTIONS

i Requirements

FRCP 23 governs class actions, where one representative sues on behalf of all other similarly situated plaintiffs. To proceed, a class must be certified under FRCP 23(a) and 23(b).

Rule 23(a) requires that the plaintiff establish that:86

  1. the class is so numerous that joinder of all members would be impracticable;
  2. common questions of law and fact apply to the class;
  3. the claims or defences of the representative parties are typical of the claims or defences of the class; and
  4. the representative parties will fairly and adequately protect the interests of the class.

Additionally, Rule 23(b) requires that the plaintiff establish one of the following:87

  1. separate actions would create a risk of 'inconsistent or varying adjudications with respect to individual class members that would establish incompatible standards of conduct for the party opposing the class';
  2. separate actions would create a risk of adjudications that 'would be dispositive of the interests of the other members not parties to the individual adjudications or would substantially impair or impede their ability to protect their interests';
  3. 'the party opposing the class has acted or refused to act on grounds that apply generally to the class, so that final injunctive relief or corresponding declaratory relief is appropriate respecting the class as a whole'; or
  4. 'questions of law or fact common to class members predominate over any questions affecting only individual members', and 'a class action is superior to other available methods for fairly and efficiently adjudicating the controversy'.

Most antitrust class action suits are certified under the fourth provision. Only 'common' questions under 23(b)(2) are relevant to the 23(b)(3) predominance analysis.88

Plaintiffs must establish that damages can be proven with class-wide evidence, that is, the case is susceptible to resolution by common proof, to satisfy 23(b)(3)'s requirement that common issues predominate.89 In some cases, plaintiffs may have recourse to representative samples to establish class-wide liability.90 Plaintiffs also must prove class-wide impact – that all class members suffered injury to their business or their property – using common proof.91 Courts have recently required more rigorous qualitative and quantitative assessments of plaintiffs' proposed common methodology for analysing class-wide impact and merits-related issues related to class certification.92 While the depth and breadth of expert testimony and the scope of pre-certification discovery necessary is decided on a case-by-case basis,93 a 'rigorous analysis' of expert opinions is required.94

Plaintiffs' ability to meet, rather than an intention to meet, the FRCP 23 requirements must be demonstrated by a preponderance of the evidence at the class certification stage. A plaintiff may meet FRCP 23 requirements even if the putative class includes a de minimis number of potentially uninjured parties.95 Thus, courts generally resolve all factual and legal disputes, including expert disputes, relevant to their certification decision at the time of class certification.

Class representatives may have to establish other threshold requirements, including that the class is in existence, ascertainable and definable with reasonable specificity;96 and that at least one class plaintiff is able to demonstrate standing.97

When a district court issues an order ruling on class certification, the parties have 15 days to request permission to appeal the decision from a court of appeals, or 45 days if the United States government is one of the parties.98 Courts are not permitted to grant discretionary extensions of the deadline to request permission to appeal a class certification decision.99

ii Appointment of class counsel

After certification, the court must appoint class counsel to adequately and fairly represent the interests of the entire class.100

iii Limitations on class-action settlements

Pre-certification settlements

Rule 23 also allows a settlement class to be certified prior to a ruling on class certification for trial purposes. To certify a settlement class, plaintiffs must satisfy the requirements of 23(a) and meet one requirement of 23(b). However, a district court need not inquire whether the case, if tried, would present intractable management problems, allowing settlement classes to be certified where potential conflicts would defeat class certification for trial.101

Court approval of class settlements required

To prevent abuse by class representatives, Rule 23(e) requires court approval of class action settlements and voluntary dismissals. Proposed class-action settlements, voluntary dismissals or compromise proposals are generally approved if the class meets the 23(a) and 23(b) requirements, and the settlement is 'fair, reasonable, and adequate'.102 Under the latter inquiry, relief under the settlement will be evaluated against the class's expected relief at trial and its likelihood of success.103 The settlement may be rejected if the court has concerns that the damages are inadequate or concerns regarding the class standing of the plaintiffs.104

Notice

Upon certification, 23(b)(3) requires notice to be provided105 'in a reasonable manner' to all class members who would be bound by the proposal.106 Typically, plaintiffs bear the cost of notice.

VIII CALCULATING DAMAGES

i Types of damages cognisable

A fact finder may assess damages where the plaintiff can provide 'probable and inferential' proof of a 'just and reasonable estimate' of damages.107 Damages cannot be proven through 'speculation or guesswork'.108 The court will award the plaintiff triple the amount of damages claimed ('treble damages'). Courts do not allow punitive damage awards because antitrust plaintiffs already receive treble damages.109

ii Calculation of damages

The appropriate measure of damages depends on the type of antitrust violation alleged. Common approaches to damages are as follows:

  1. The difference between the plaintiff's purchase price and the price the purchaser would have paid if not for the violation is a common approach where the alleged effect of the violation is an overcharge, such as cartel claims (e.g., price fixing, bid-rigging, market allocations or output limitation agreements) or monopolisation.110
  2. The difference between the plaintiff's purchase price and the price the purchaser would have paid on the open competitive market is a common measure of damages in tying cases.111 A plaintiff may be entitled to recovery only when the fair market value of the tying and tied products exceeds their combined purchase price.112
  3. The plaintiff's lost profits is a common measure of damages in cases where the plaintiff is a competitor excluded from the market or is a disfavoured purchaser in a price discrimination case.113 Damages are usually limited to lost net profits, although some courts may award lost gross profits if lost net profits are negligible.114 When the plaintiff's business has been almost or completely destroyed, courts may measure damages by lost goodwill or going concern value (i.e., the current value of lost future profits).115

iii Mitigation

A plaintiff must mitigate damages and cannot recover losses that could have been avoided.116

iv Disaggregation

A plaintiff may only collect damages for losses caused by the defendant's antitrust violation. Therefore, the plaintiff must provide the fact finder a basis to disaggregate the losses caused by other factors.117 If it does not, a damages award may be overturned on the grounds it is based on speculation and guesswork.118

v Other costs

Section 4 also awards successful plaintiffs' court costs, reasonable attorneys' fees, prejudgment interest on actual damages (awarded at the court's discretion if the court finds it 'just in the circumstances') and mandatory post-judgment interest.119

IX PASS-ON DEFENCES

Antitrust defendants are barred from asserting pass-on defences against direct purchasers. Therefore, defendants may not introduce evidence that indirect purchasers, rather than the direct purchasers,120 were in fact harmed by the defendants' antitrust violations. This bar against pass-on defences is analogous to the earlier-noted bar against claims by indirect purchasers, preventing the defensive and offensive use of the pass-on theory to prevent duplicate recovery against defendants.121

Lower courts, however, have recognised three narrow exceptions to this general ban against pass-on defences and indirect purchaser claims:

  1. for pre-existing, fixed-quantity, cost-plus contracts, because the plaintiff may show that the indirect purchaser, not the direct purchaser, was harmed by any anticompetitive overcharge;122
  2. where the direct purchaser (i.e., the intermediary) is owned or controlled by either the defendant or the indirect purchaser such that the relationship involved 'such functional economic or other unity between the direct purchaser and either the defendant or the indirect purchaser that there effectively has been only one sale';123 and
  3. where the intermediary is a direct participant in a conspiracy with the defendant, such that the intermediary and defendant are then viewed as a single entity from which the plaintiff is a direct purchaser.124

X FOLLOW-ON LITIGATION

i Prima facie evidence

A government judgment or decree may be prima facie evidence in a private antitrust suit if the government judgment or decree is:

  1. final;
  2. rendered in a civil or criminal proceeding brought by or on behalf of the United States;
  3. under the antitrust laws to the effect that a defendant has violated said laws; and
  4. is not a consent judgment or decree entered before any testimony has been taken.125

Additionally, the private plaintiff must be injured in fact by the antitrust violation proven in the government action.126 Guilty pleas to a Department of Justice (DOJ) indictment generally are admissible as evidence in subsequent private litigation.127 Since DOJ and FTC consent decrees are typically for settlement purposes, they do not constitute an admission by the defendant that the law has been violated.128

The prima facie effect is given to all matters 'distinctly put in issue and directly determined' and 'necessarily decided' against the defendant in the government proceeding,129 but is limited to the period, products and geographical scope adjudicated in the prior government action.130

ii Collateral estoppel

The collateral estoppel doctrine applies in private antitrust suits.131 Generally, the doctrine bars the retrying of issues that have already been determined by a court, and gives them conclusive effect in subsequent suits that involve a party to the prior litigation.132 A defendant can use collateral estoppel doctrine defensively to prevent a plaintiff from re-litigating issues previously decided and lost by the government,133 while a plaintiff can use collateral estoppel offensively to bar a defendant from re-litigating issues lost in prior government actions. Collateral estoppel applies to prior DOJ actions, but not to findings made by the FTC.134

Section 213(a) of the Antitrust Criminal Penalty Enhancement and Reform Act of 2004 (ACPERA)135 offers criminal defendants who participate in the DOJ's corporate leniency programme the opportunity to limit civil liability to single rather than treble damages if they provide 'satisfactory cooperation' to civil claimants. To qualify, defendants must provide a full account of relevant facts, furnish all relevant documents, and participate in interviews and depositions reasonably requested by the plaintiff. ACERPA does not affect the plaintiff's right to recover costs, attorneys' fees and prejudgment interest provided under the Clayton Act.

XI PRIVILEGES

i Attorney–client privilege

Attorney–client privilege protects confidential communications between an attorney and client made for the purpose of rendering or receiving legal advice, and applies in the antitrust context to the same extent as in other contexts. The privilege extends to confidential communications between corporate employees and the corporation's lawyer when those communications are necessary to facilitate the provision of legal advice to the corporation,136 and covers communications with current and former employees,137 subsidiaries and affiliates.138 It does not extend to communications with a lawyer acting in a business capacity.139

ii Waiver of attorney–client privilege

Privilege is waived if a communication is voluntarily disclosed to a third party,140 unless disclosure is necessary to provide legal advice (e.g., a secretary or an interpreter) or is part of the community-of-interest (or joint defence) privilege.141 Privilege may be waived if the corporation voluntarily discloses communications to third-party government agencies.142

iii The crime-fraud exception

Communications made between clients and their attorneys for the purpose of furthering a current or future crime or fraud, such as an antitrust law violation, are not privileged.143 To invoke the exception, the moving party must make a prima facie showing that the allegation of a crime or fraud is founded in fact and was intended to further that crime or fraud.144

iv Foreign communications and documents

Attorney–client communications that occur in a foreign country or involve foreign attorneys or proceedings and attorney work for foreign proceedings is governed by common law principles.145 Principles of international comity dictate that the law of the country with the most 'predominant' or 'direct and compelling' interest in whether those communications should remain confidential applies, unless it would be contrary to public policy.146 The 'predominant' jurisdiction is usually the jurisdiction in which the attorney–client relationship was formed or where the relationship was centred at the time the privileged communication was sent.147

The Hague Evidence Convention allows discovery of foreign evidence; however, Article 11 safeguards privileged and protected evidence under the law of the 'state of execution' or 'state of origin'.

v Attorney work product doctrine

The work product doctrine protects all documents and tangible materials prepared by or for an attorney in anticipation of litigation.148 Ordinary fact work product includes materials in which the attorney merely records or summarises information, while opinion work product includes materials that reflect the attorney's mental impressions, opinions, judgments or legal conclusions.149 While opinion work product is virtually immune from discovery,150 a discovering party may obtain fact work product if it shows substantial need for the work product and undue hardship in obtaining the information from another source.151 The crime-fraud exception applies to ordinary attorney fact work product, but courts will maintain the immunity given the more sacrosanct opinion work product if the lawyer had no knowledge of the client's crime or fraud.152

XII SETTLEMENT PROCEDURES

Federal policy generally favours settlement over continued litigation. FRCP 16 allows federal judges to mandate pretrial conferences among the parties to, inter alia, facilitate settlement, and allows them to impose sanctions on parties for failing to appear or for failing to participate in good faith at such conferences.153 With the exception of class action settlements, courts typically accept a party's stipulation to settle without review. However, FRCP 23 requires that proposed class-action settlements be reviewed and approved by the court only if they are 'fair, reasonable, and adequate' as class section settlements affect the rights of all class members.154 A defendant's unaccepted offer of settlement to a class representative does not moot the plaintiff's claim.155 Due process requirements – giving notice to the absent class members and holding a hearing in which any such absent class member who wishes to may object to the proposed settlement – must be met prior to settlement approval.156

XIII ARBITRATION

Federal policy favours arbitration, and federal antitrust claims arising out of both international and domestic transactions generally may be arbitrated.157 Arbitration clauses are construed broadly,158 and courts refuse to recognise attempts by parties to limit the statutory remedies and procedures available to arbitrators, invalidating, for example, portions of arbitration agreements where the parties attempted to waive rights to treble damages or class or consolidated actions.159 Courts may not decline to enforce arbitration agreements that delegate to an arbitrator the question of whether a dispute should be arbitrated.160 In the context of class actions, however, the defendant's arbitration rights may be deemed waived if it seeks to compel arbitration only after the class is certified and extensive discovery has occurred.161 In addition, arbitrators may not impose class arbitration on parties unless it is contractually permissible.162 The Supreme Court has held that express arbitration clauses trump class-action rights, even in antitrust cases.163

XIV INDEMNIFICATION AND CONTRIBUTION

i Joint and several liability

Under the doctrine of joint and several liability, each guilty defendant is liable for all the damages caused by the conduct of the entire conspiracy, not just those attributable to its own conduct.164 Antitrust co-conspirators can be held jointly and severally liable for damage predicated on sales by members of the conspiracy and damage caused by entities outside the conspiracy caused by the conspiracy.

ii No right to contribution

An antitrust defendant may not seek contribution from other participants in the anticompetitive scheme.165 Combined with joint and several liability for antitrust damages among defendants, the absence of the right to seek contribution from others has important practical consequences for defendants in their settlement strategies.

iii Indemnification

Most courts prohibit a defendant from seeking indemnification from other participants of an anticompetitive conspiracy, treating contribution and indemnification analogously.166 However, indemnification may be available to 'an innocent actor whose liability stems from some legal relationship with the truly culpable party'.167

XV ENFORCEMENT OF MONETARY JUDGMENTS AGAINST FOREIGN COMPANIES

Monetary judgments issued by US courts generally become enforceable promptly after entry, and taking an appeal from the judgment does not ordinarily stay enforcement.168 To stay enforcement pending appeal, the losing defendant (or 'judgment debtor') must ordinarily post a bond for the full amount of the monetary judgments.169 Enforcement of monetary judgments in US federal courts is governed by FRCP 69.170

The principal device contemplated by that rule is the 'writ of execution' (i.e., an order authorising US marshals to seize and sell property of the judgment debtor within the territory of the district court).171 The holder of a monetary judgment (or 'judgment creditor') may register the judgment in other district courts, in which case the judgment is treated as though it had issued from the court in which it has been registered.172 Rule 69 authorises proceedings in aid of enforcement, including post-judgment discovery as to the judgment debtor's assets.173 The US Supreme Court recently held that such discovery may extend to assets held abroad because the judgment creditor may be able to secure execution in the countries where the assets are held.174

US courts generally do not have authority to execute against assets outside the United States.175 However, the enforcement law of the state of New York authorises orders requiring any judgment debtor or third party over which it has personal jurisdiction to bring money or personal property belonging to the judgment debtor into the state for execution.176 The constitutionality of this approach remains an open question.177

XVI FUTURE DEVELOPMENTS AND OUTLOOK

Private antitrust litigation continues to be active in the United States, both in class action litigation for consumers against companies that have engaged in anticompetitive conduct and for private companies challenging the practices of other companies as anticompetitive. Additionally, follow-on litigation to government enforcement action, particularly in cartel matters, continues to be a large part of US antitrust litigation.

US courts continuously evaluate the scope of the antitrust laws and the legal framework in which plaintiffs may bring private litigation. Likewise, the appellate courts continue to interpret Bell Atlantic v. Twombly178 and clarify what allegations are sufficient to create a 'reasonably grounded expectation that discovery will reveal relevant evidence of an illegal agreement' to survive dismissal.179

While the Supreme Court currently has no pending antitrust cases, appellate courts are active in interpreting and applying US antitrust law. Two appellate courts are currently considering the scope of antitrust liability for refusals to deal.180 In both cases, the DOJ has stepped in to advocate for the courts to adopt a standard that would require plaintiffs alleging anticompetitive refusals to deal to show that there was no rational reason for the refusal to deal, that is, that the refusal made sense only as a means of reducing or eliminating competition (by contrast, plaintiffs in these cases advocate for more lenient standards).181 The active debate around the appropriate standard may signal that a case dealing with the scope of refusal to deal liability will soon be appealed to the Supreme Court. Over the past three years, the US Supreme Court has rendered several decisions concerning general litigation issues of potential relevance to antitrust disputes. In particular, in May the Court ruled that the Convention on the Service Abroad of Judicial and Extrajudicial Documents in Civil or Commercial Matters authorises service of process by mail.182 In another case, the Supreme Court further clarified the boundaries of personal jurisdiction: building upon its 2014 Daimler183 decision, the Court explained that a state court cannot establish general jurisdiction over an out-of-state defendant that is not incorporated nor maintains its principal place of business in that state.184

Further developments in class action litigation and substantive antitrust law have come from the federal appellate courts in recent years. For example, in the context of settling patent infringement disputes between generic and brand-name drug manufacturers, there is still substantial disagreement between the circuits as to whether plaintiffs are required to prove that the pharmaceutical company who sought generic entry would have won the patent litigation had defendants not settled.185 The Third Circuit in In re Lipitor Antitrust Litigation rejected the heightened pleading standard the District Court applied in a recent reverse payments case.186 The panel explained that defendants – not plaintiffs – have the burden to justify the rather large reverse payment.187 In DeHoog v. Anheuser-Busch InBev SA/NV, the Ninth Circuit ruled that private plaintiffs could not challenge a merger as anticompetitive where the government had required the target to divest its business interest in the US beer market, reducing the likelihood of anticompetitive effects.188 The Court of Appeals for the DC Circuit recently upheld a district court decision rejecting the DOJ's effort to block the merger of AT&T and Time Warner, issuing a fact-specific decision focused on evidence about the market in question that declined to adopt general standards for the review of vertical mergers.189 The court's focus on market realities and reluctance to develop new law may be seen by future courts as a tacit approval of existing merger law, and suggests that – for now – challenges to mergers will depend on concrete evidence that the merger in question will have anticompetitive effects.

The development of the law on the procedures for bringing antitrust actions, including the evolution of pleading and class certification standards as well as the continued enforcement by the federal antitrust agencies and state authorities against cartel activities and monopolisation across industries, virtually assures that private litigation will remain a robust and complex area of activity in the United States.

31 15 USC Section 6a. Where conduct involves import trade or commerce, the FTAIA does not apply and courts instead apply the common law 'intended effects' test, requiring that the foreign anticompetitive conduct was intended to and actually affected US trade or commerce.

49 15 USC Section 15. Section 12(a) defines 'persons' as 'corporations and associations existing under or authorized by laws of either the United States, the laws of any of the Territories, the laws of any State, or the laws of any foreign country'. Courts have also interpreted 'persons' to include individual consumers (e.g., Reiter v. Sonotone Corporation, 442 US 330, 340–42 (1979)), partnerships (e.g., Coast v. Hunt Oil Co, 195 F2d 870, 871 (5th Cir 1952)), states (e.g., Standard Oil Co v. Arizona, 738 F2d 1021, 1023 (9th Cir 1984)) and foreign governments (Pfizer v. Government of India, 434 US 308, 318–20 (1978)). Section 4 of the Clayton Act (15 USC Section 15(b)) generally limits recovery by foreign governments to actual, instead of treble, damages. While the United States and state attorneys general are not considered 'persons' under the Clayton Act, they are nonetheless entitled to sue on their own behalf under Sections 4A and 4C of the Clayton Act (15 USC Sections 15a, 15c).
