Anti-Arbitration Injunction Proceedings in Europe

1. Introduction

Anti-arbitration injunction proceedings are court proceedings in which a national court is asked to order a party not to commence, continue, or pursue arbitration proceedings.

They are different from an anti-suit injunction, which ordinarily seeks to restrain litigation before a national court. An anti-arbitration injunction specifically targets an arbitration.

Typical applications arise where a party argues that:

there is no valid arbitration agreement;

the arbitration clause is inapplicable;

the tribunal lacks jurisdiction;

the dispute falls outside the arbitration agreement;

arbitration was commenced in breach of an exclusive jurisdiction agreement;

the arbitration is contrary to mandatory law;

the arbitration would undermine proceedings already pending before another court;

the arbitration is abusive or vexatious;

the arbitration violates an applicable treaty or public-policy requirement.

A central difficulty in Europe is that arbitration is governed by national procedural law while also being affected by EU law and the European Convention on Human Rights.

2. Meaning of an Anti-Arbitration Injunction

An anti-arbitration injunction is essentially a judicial order directed against a party requiring that party to refrain from:

commencing arbitration;

continuing an arbitration;

appointing or participating in the constitution of an arbitral tribunal;

pursuing particular claims in arbitration;

enforcing or relying upon arbitration proceedings in certain circumstances.

The order normally operates against the party, rather than directly against the arbitral tribunal.

This distinction is important.

A national court generally cannot simply command an arbitral tribunal sitting in another jurisdiction to stop. Instead, it may order the litigant before it not to pursue the arbitration.

3. Why Anti-Arbitration Proceedings Are Controversial

Arbitration rests on several fundamental principles:

party autonomy;

separability of the arbitration agreement;

competence-competence;

limited judicial intervention;

procedural efficiency;

recognition and enforcement of arbitral awards.

An anti-arbitration injunction potentially interferes with each of these principles.

The court therefore has to balance:

judicial supervision of arbitration

against

respect for the arbitral process and party autonomy.

4. Anti-Arbitration Injunction Versus Anti-Suit Injunction

An anti-arbitration injunction is therefore not simply an anti-suit injunction with different terminology.

5. Sources of European Law

Anti-arbitration proceedings can involve several legal regimes.

A. National arbitration law

National arbitration legislation determines:

validity of arbitration agreements;

tribunal jurisdiction;

court intervention;

interim measures;

challenges to awards;

enforcement.

B. New York Convention

The 1958 New York Convention is central to:

recognition of arbitration agreements;

recognition and enforcement of awards;

jurisdictional objections.

C. EU law

EU law becomes important where:

the arbitration concerns EU law;

an intra-EU investment dispute is involved;

an arbitral process interferes with EU judicial autonomy;

national courts must apply EU mandatory rules.

D. ECHR

Article 6 of the European Convention on Human Rights may become relevant to:

access to justice;

procedural fairness;

voluntary arbitration;

impartiality;

effective judicial supervision.

E. National constitutional principles

Constitutional courts may also consider:

access to courts;

judicial independence;

separation of powers;

supremacy/autonomy of EU law.

6. Competence-Competence

One of the most important principles is competence-competence.

An arbitral tribunal generally has authority to determine its own jurisdiction, including objections concerning:

existence of the arbitration agreement;

validity;

scope;

applicability;

jurisdiction over the particular dispute.

This creates an important question:

If the tribunal itself can decide jurisdiction, why should a national court stop the arbitration beforehand?

Courts are therefore often cautious about granting anti-arbitration injunctions.

However, competence-competence does not necessarily eliminate all judicial intervention.

7. Separability of the Arbitration Agreement

An arbitration clause is generally treated as legally separate from the underlying contract.

Therefore:

A party cannot necessarily defeat arbitration simply by alleging that the main contract is invalid.

The tribunal may still have jurisdiction to determine whether the underlying contract is invalid.

This is known as the separability doctrine.

8. Grounds for Seeking an Anti-Arbitration Injunction

Possible grounds include:

1. No arbitration agreement

The claimant argues that it never agreed to arbitrate.

2. Invalid arbitration agreement

The arbitration clause may allegedly be invalid because of:

lack of authority;

incapacity;

fraud;

illegality;

lack of consent;

contractual defects.

3. Dispute outside the arbitration clause

The clause may exist but not cover the particular dispute.

4. Arbitration commenced contrary to the contract

For example, the contract may require:

negotiation;

mediation;

expert determination;

before arbitration.

5. Lack of tribunal jurisdiction

There may be objections concerning:

appointment;

composition;

seat;

subject matter;

territorial jurisdiction.

6. Abuse of arbitration

A party may allege that arbitration is being used:

oppressively;

vexatiously;

fraudulently;

to evade mandatory law.

7. Violation of mandatory EU law

This can be particularly significant where arbitration threatens the autonomy or effectiveness of EU law.

9. The CJEU's Important Approach: West Tankers

1. Allianz SpA and Generali Assicurazioni Generali SpA v West Tankers Inc., C-185/07

CJEU, 10 February 2009

This is one of the most important European authorities concerning injunctions and arbitration.

The dispute arose from a collision involving the vessel Front Comor.

Proceedings were brought in England pursuant to an arbitration agreement, while related litigation existed in Italy.

The English court granted an anti-suit injunction intended to restrain the Italian proceedings.

The CJEU held that an anti-suit injunction restraining proceedings before a court of another EU Member State was incompatible with the Brussels jurisdictional framework, because the foreign court was entitled to determine its own jurisdiction.

Importance for anti-arbitration proceedings

West Tankers demonstrates the European Union's strong concern for:

mutual trust;

autonomy of Member State courts;

allocation of jurisdiction;

limits on one Member State court interfering with another Member State court.

But it must be distinguished carefully:

West Tankers was an anti-suit injunction case, not a general prohibition on every anti-arbitration injunction.

10. Gazprom — Important Counterpoint

2. Gazprom OAO v Lietuvos Respublika

C-536/13, CJEU, 13 May 2015

This is an extremely important arbitration authority.

The CJEU considered an arbitral award that effectively required a party to refrain from pursuing certain proceedings before Lithuanian courts.

The Court distinguished arbitration from the situation considered in West Tankers.

The EU Brussels jurisdiction regime did not apply to arbitration in the same way.

Importance

Gazprom demonstrates that:

EU law does not automatically treat arbitral proceedings as equivalent to proceedings before Member State courts.

It therefore prevents an overbroad interpretation of West Tankers.

11. Achmea

3. Slovak Republic v Achmea BV

C-284/16, CJEU, 6 March 2018

Achmea concerned an arbitration clause in an intra-EU bilateral investment treaty.

The CJEU held that the arbitration mechanism was incompatible with EU law because it could remove disputes involving EU law from the EU judicial system and undermine the autonomy of EU law.

Importance for anti-arbitration proceedings

Achmea established a major European limitation on certain forms of intra-EU investment arbitration.

Where an arbitration agreement or treaty mechanism conflicts with EU judicial autonomy, national courts may have grounds to prevent its operation or refuse its effects under applicable national/EU law.

12. Komstroy

4. Republic of Moldova v Komstroy

C-741/19, CJEU, 2 September 2021

The CJEU continued the Achmea approach in relation to arbitration under the Energy Charter Treaty in an intra-EU context.

The Court held, in substance, that the intra-EU application of the ECT arbitration mechanism could not circumvent the autonomy of EU law.

Importance

Komstroy is relevant when an anti-arbitration application argues that:

arbitration concerns an intra-EU dispute;

the tribunal may interpret EU law;

the arbitral mechanism undermines the jurisdiction of EU courts.

It demonstrates that arbitration agreements do not automatically prevail over EU constitutional principles.

13. Eco Swiss

5. Eco Swiss China Time Ltd v Benetton International NV

C-126/97, CJEU, 1 June 1999

The CJEU held that certain fundamental EU competition-law rules must be treated as matters of public policy in the context of arbitral proceedings.

The case concerned Article 101 TFEU principles.

Importance

Eco Swiss shows that arbitration cannot be used as a mechanism for avoiding mandatory EU competition law.

It is relevant where a party seeks judicial intervention because the arbitration allegedly involves:

anti-competitive agreements;

abuse of competition rules;

mandatory EU economic law.

It also demonstrates the continuing importance of public policy review at the enforcement/set-aside stage.

14. Mostaza Claro

6. Mostaza Claro v Centro Móvil Milenium SL

C-168/05, CJEU, 26 October 2006

The case concerned an arbitration clause in a consumer contract.

The CJEU emphasized the mandatory nature of EU consumer protection.

Principle

An unfair consumer arbitration clause cannot necessarily be enforced merely because arbitration has been agreed.

Relevance

An anti-arbitration application may therefore be particularly strong where:

the claimant is a consumer;

the arbitration clause is unfair;

the clause deprives the consumer of effective legal protection.

15. Asturcom

7. Asturcom Telecomunicaciones SL v Cristina Rodríguez Nogueira

C-40/08, CJEU, 6 October 2009

Asturcom concerned an arbitration clause in a consumer contract and the ability of national courts to address unfairness.

The CJEU reinforced the importance of effective consumer protection.

Importance

The case demonstrates that:

procedural finality and arbitration cannot always prevent judicial examination of mandatory consumer protections.

This can support an argument against enforcing or continuing an arbitration based on an unfair consumer clause.

16. Achmea and the Autonomy of EU Law

Achmea is especially important because it establishes a broader constitutional principle.

EU law requires a judicial system capable of ensuring:

uniform interpretation of EU law;

effective judicial protection;

Article 19 TEU judicial supervision;

autonomy of the EU legal order.

An arbitral tribunal outside the ordinary EU judicial structure may create difficulties where it has authority to give binding interpretations of EU law.

This is why intra-EU investment arbitration has become a particularly important area of anti-arbitration litigation.

17. ECHR: Deweer v Belgium

8. Deweer v Belgium, Application No. 6903/75

ECtHR, 27 February 1980

The European Court of Human Rights examined the concept of waiver of judicial rights.

The Court recognized that a person may waive certain judicial rights, including through mechanisms involving settlement or arbitration, but the waiver must be:

established unequivocally;

attended by safeguards;

voluntary;

compatible with fundamental rights.

Relevance

An anti-arbitration claim may therefore become relevant where arbitration was allegedly:

imposed unfairly;

not genuinely consented to;

forced upon a weaker party;

incorporated through an unfair contractual mechanism.

18. Lithgow and Others v United Kingdom

9. Lithgow and Others v United Kingdom

Applications Nos. 9006/80 and Others, ECtHR, 8 July 1986

The Court recognized that Article 6 does not prohibit every procedural limitation on access to courts.

Restrictions may be permissible where they:

pursue a legitimate aim;

are proportionate;

do not destroy the essence of the right.

Relevance

This creates a balancing framework for arbitration.

Arbitration is not automatically inconsistent with Article 6 merely because it substitutes private adjudication for ordinary court proceedings.

But serious procedural unfairness can change the analysis.

19. Suda v Czech Republic

10. Suda v Czech Republic, Application No. 1643/06

ECtHR, 28 October 2010

The Court examined arbitration-related procedural issues under Article 6.

The case is important for the proposition that arbitration does not exist entirely outside the Convention's fair-trial framework.

Where arbitration effectively determines civil rights and obligations, relevant procedural safeguards may become significant.

Relevance

Anti-arbitration proceedings may therefore be justified where the proposed arbitral mechanism is alleged to create serious and unavoidable procedural unfairness.

20. The “Competence-Competence vs Court Intervention” Problem

This is the central procedural conflict.

Arbitration side

The respondent may argue:

“The tribunal has jurisdiction to decide its own jurisdiction.”

Court side

The applicant may respond:

“There is no arbitration agreement at all, or the arbitration is legally impossible.”

Courts must determine whether the objection is sufficiently serious to justify intervention before the tribunal completes the arbitral process.

The precise threshold depends on national law.

21. Prima Facie Review

Many arbitration systems permit courts to conduct some form of preliminary examination.

The court may ask:

Is there apparently an arbitration agreement?

Is the clause facially valid?

Does the dispute apparently fall within it?

Is there an obvious jurisdictional defect?

Is intervention necessary now?

A court may be reluctant to conduct a complete merits analysis at the injunction stage.

22. Interim Injunction Requirements

Where national procedural law permits an anti-arbitration injunction, courts commonly consider factors such as:

1. Serious issue

Is there a credible legal basis for challenging the arbitration?

2. Jurisdiction

Does the court have authority to grant the injunction?

3. Irreparable or substantial harm

Would continuing arbitration cause harm that cannot adequately be remedied later?

4. Balance of convenience/proportionality

Would the injunction cause greater harm than allowing arbitration to continue?

5. Adequacy of alternative remedies

Can the applicant simply challenge jurisdiction before the tribunal and later challenge the award?

6. Good faith

Is the application genuinely jurisdictional, or merely an attempt to delay arbitration?

23. Why Courts Are Often Reluctant to Intervene

A party normally has alternative remedies:

object to jurisdiction before the tribunal;

challenge an interim jurisdictional ruling where permitted;

challenge the final award;

seek annulment at the seat;

resist enforcement.

Consequently, a court may conclude:

“You have an adequate remedy in the arbitration itself and subsequent judicial review.”

This can make an anti-arbitration injunction difficult to obtain.

24. When Intervention Becomes More Persuasive

The argument becomes stronger where:

there is clearly no arbitration agreement;

the arbitration is plainly outside the contractual scope;

the arbitration is brought against a non-party;

the arbitration violates mandatory law;

the tribunal lacks a legally permissible jurisdictional basis;

the proceedings are fraudulent or oppressive;

continuing the arbitration would cause exceptional prejudice;

EU constitutional principles are directly implicated;

consumer protection would be seriously undermined.

25. Anti-Arbitration Injunctions and Arbitration Agreements

Courts distinguish between:

“No agreement”

and

“Agreement exists but tribunal has interpreted it incorrectly.”

The first may justify stronger judicial intervention.

The second is often more appropriately left to the arbitral tribunal under competence-competence principles, subject to later judicial review.

26. Anti-Arbitration Injunctions and Consumer Contracts

Consumer cases are particularly sensitive.

A consumer may argue:

the arbitration clause is unfair;

the clause was not properly incorporated;

the clause creates a significant imbalance;

arbitration costs are disproportionate;

the clause restricts effective access to courts.

Mostaza Claro and Asturcom are important here.

The consumer-protection principle is:

contractual consent to arbitration does not necessarily override mandatory consumer rights.

27. Anti-Arbitration Injunctions and Competition Law

Eco Swiss demonstrates that arbitration must respect mandatory EU competition law.

Therefore, a party may raise competition-law objections where arbitration threatens to:

enforce an anti-competitive arrangement;

prevent application of Article 101 TFEU;

undermine mandatory competition rules.

However, the mere allegation that competition law is involved does not automatically require an anti-arbitration injunction.

28. Anti-Arbitration Injunctions and Investment Arbitration

This is one of the most important modern areas.

The sequence is:

EU law → autonomy of EU judicial system → limits on intra-EU investment arbitration → possible national judicial intervention.

The key cases are:

Achmea;

Komstroy.

Related litigation has concerned:

intra-EU BITs;

Energy Charter Treaty arbitration;

enforcement of awards;

set-aside proceedings;

state immunity;

EU-law primacy.

29. Anti-Arbitration Injunction and State Courts

A national court should distinguish between:

Restraining a party

and

Directing a tribunal.

The former is generally the practical form of an injunction.

For example:

“The defendant shall not take further steps in the arbitration.”

is different from:

“The arbitral tribunal is ordered to terminate the arbitration.”

The second formulation creates significantly greater jurisdictional and comity problems.

30. Public Policy

Public policy can become relevant at multiple stages:

Before arbitration

A court may consider whether continuing the arbitration would violate mandatory public policy.

During arbitration

The tribunal may have to apply mandatory rules.

After arbitration

A national court may refuse enforcement or annul an award on public-policy grounds.

The last two mechanisms often reduce the perceived necessity for a pre-emptive anti-arbitration injunction.

31. Relationship With Annulment Proceedings

A party should not automatically use an anti-arbitration injunction when a normal annulment mechanism is available.

The procedural sequence can instead be:

Arbitration → award → set-aside proceedings at seat → enforcement proceedings.

Anti-arbitration proceedings attempt to intervene earlier:

Agreement → arbitration begins → court intervention → arbitration stopped.

The earlier intervention occurs, the stronger the justification normally needs to be.

32. Relationship With Anti-Suit Injunctions

The cases should not be conflated.

West Tankers

Primarily concerns an anti-suit injunction affecting proceedings in another EU Member State.

Gazprom

Demonstrates the different treatment of arbitration.

Therefore:

West Tankers should not be read as creating a blanket European prohibition against anti-arbitration injunctions.

That distinction is essential.

33. Abuse of Process

An anti-arbitration application can itself be abusive.

For example, a party may:

sign an arbitration agreement;

participate in appointment of the tribunal;

participate in procedural hearings;

then seek an injunction simply because the arbitration is going badly.

A court may treat such conduct critically, particularly where the applicant has delayed raising the jurisdictional objection.

34. Delay and Waiver

Arbitration laws commonly require jurisdictional objections to be raised promptly.

A party that knowingly participates without timely objection may face arguments based on:

waiver;

estoppel;

procedural default;

abuse of process.

Therefore, an applicant should generally raise jurisdictional objections as soon as reasonably possible.

35. Evidence Required

An anti-arbitration application should normally establish:

Contractual evidence

arbitration agreement;

underlying contract;

amendments;

incorporation documents;

correspondence.

Arbitration evidence

notice of arbitration;

request for arbitration;

tribunal constitution;

procedural orders;

jurisdictional submissions.

Jurisdictional evidence

governing law;

seat;

scope of clause;

party identity;

dispute nature.

Prejudice evidence

costs;

parallel proceedings;

irreversible procedural consequences;

risk of conflicting decisions;

regulatory consequences.

36. Typical Procedural Structure

1. Arbitration commenced

↓

2. Respondent objects to jurisdiction

↓

3. Application to competent national court

↓

4. Court considers jurisdiction to grant injunction

↓

5. Court applies interim-relief standard

↓

37. Case-Law Summary Table

38. Six Most Important Cases to Remember

If the topic is being studied for an examination or legal research paper, the six most important authorities are:

1. West Tankers — C-185/07

Anti-suit injunction + EU judicial jurisdiction.

2. Gazprom — C-536/13

Arbitration is not simply equivalent to Member State court litigation.

3. Achmea — C-284/16

Intra-EU investment arbitration and EU-law autonomy.

4. Komstroy — C-741/19

Intra-EU ECT arbitration and EU judicial autonomy.

5. Eco Swiss — C-126/97

Mandatory EU competition law and arbitral proceedings.

6. Mostaza Claro — C-168/05

Unfair consumer arbitration clauses and mandatory consumer protection.

39. Practical Legal Test for an Anti-Arbitration Injunction

A European court considering such an application can be analysed through the following questions:

Question 1

Is there a valid arbitration agreement?

Question 2

Who are the parties to that agreement?

Question 3

Does the dispute fall within its scope?

Question 4

What is the seat of arbitration?

Question 5

What law governs the arbitration agreement?

Question 6

Does the arbitral tribunal have competence-competence under the applicable law?

Question 7

Is there an obvious jurisdictional defect?

Question 8

Is there a mandatory EU-law or public-policy problem?

Question 9

Would allowing arbitration to continue cause serious and irreparable prejudice?

Question 10

Is an ordinary jurisdictional objection or later award challenge an adequate remedy?

Question 11

Would the injunction interfere impermissibly with another country's judicial or arbitral process?

Question 12

Has the applicant acted promptly and consistently?

40. Key Defences Against an Anti-Arbitration Injunction

The arbitration claimant will commonly argue:

A. Valid arbitration agreement

The applicant agreed to arbitration.

B. Competence-competence

The tribunal should determine its own jurisdiction.

C. Adequate alternative remedy

The applicant can challenge jurisdiction within the arbitration and later challenge the award.

D. No irreparable harm

Participation in arbitration does not necessarily create irreversible prejudice.

E. Delay

The applicant waited too long to object.

F. Waiver

The applicant participated in the arbitration without timely objection.

G. Forum/seat principles

The courts of the seat are the appropriate courts to supervise the arbitration.

H. Abuse of process

The injunction application is merely tactical or intended to delay the arbitration.

41. Remedies Other Than an Anti-Arbitration Injunction

Because injunctions can be exceptional, other remedies may be preferable:

jurisdictional objection before the tribunal;

challenge to tribunal jurisdiction;

challenge to tribunal constitution;

annulment/set-aside proceedings;

refusal of recognition or enforcement;

declaration concerning the arbitration agreement;

interim protective measures;

damages in exceptional circumstances;

regulatory or public-law remedies.

42. Important European Principle

The most important proposition is:

There is no general European rule that national courts may freely stop arbitration merely because a party disputes arbitral jurisdiction.

The court must consider:

the arbitration agreement;

competence-competence;

the law of the seat;

EU law;

public policy;

consumer protection where relevant;

ECHR guarantees;

availability of later judicial review;

proportionality;

comity and judicial autonomy.

At the same time, arbitration is not immune from judicial control.

43. Conclusion

Anti-arbitration injunction proceedings occupy a particularly sensitive position at the intersection of arbitration law, national procedural law, EU law and human-rights law.

The basic European approach can be summarized as:

Respect arbitration where a valid arbitration agreement exists, but intervene where continuing the arbitration would be legally impermissible, would undermine mandatory law, or would produce a sufficiently serious jurisdictional or procedural injustice.

The most significant authorities establish several complementary principles:

West Tankers limits judicial interference with courts of other EU Member States;

Gazprom confirms that arbitration has a distinct legal position;

Achmea and Komstroy protect the autonomy of EU law against certain intra-EU investment arbitration mechanisms;

Eco Swiss prevents arbitration from neutralising mandatory EU competition law;

Mostaza Claro and Asturcom protect consumers against unfair arbitration clauses;

Deweer, Lithgow and Suda establish that arbitration must remain compatible with fundamental procedural rights.

Accordingly, an anti-arbitration injunction is best understood not as an ordinary procedural weapon against arbitration, but as an exceptional judicial mechanism used where the applicant can establish a sufficiently strong jurisdictional, statutory, public-policy, EU-law or fundamental-rights basis for preventing the arbitral process from proceeding.
