How to Apply for an Injunction in a Contract Dispute

An injunction is a court order that requires a party to do something or to stop doing something. In contract disputes, injunctions are commonly used to prevent ongoing or threatened breaches of contract, preserve the status quo, or protect contractual rights before a final trial takes place.

In England and Wales, injunctions are discretionary remedies granted by the civil courts under their equitable jurisdiction, primarily the High Court. They are often used where damages would not be an adequate remedy, particularly in commercial disputes involving confidentiality clauses, restrictive covenants, supply agreements, or exclusivity obligations.

This article explains how to apply for an injunction in a contract dispute, the legal tests the court applies, and the procedural steps involved under the Civil Procedure Rules (CPR).

What an Injunction Is in a Contract Dispute

An injunction is a court order that may:

• Prevent a party from breaching a contract (prohibitory injunction)
• Require a party to take specific steps to comply with a contract (mandatory injunction)
• Operate temporarily until trial (interim injunction)
• Operate permanently after final judgment (final injunction)

In contract disputes, interim injunctions are most commonly sought, particularly where urgent harm is alleged.

An interim injunction is a temporary order designed to maintain the position until the court can fully determine the dispute.

Legal Basis for Injunction Applications

The court's power to grant injunctions arises from:

• Section 37 Senior Courts Act 1981
• CPR Part 25 (Interim Remedies)
• The court's inherent equitable jurisdiction

The procedure for making applications is governed by CPR Part 23 and CPR Part 25, including requirements for evidence, notice, and hearing arrangements.

When Injunctions Are Used in Contract Disputes

Common contractual scenarios include:

• Breach of restrictive covenants (non-compete or non-solicitation clauses)
• Misuse of confidential information
• Wrongful termination of supply or distribution agreements
• Breach of exclusivity clauses
• Attempts to transfer assets or contractual rights in breach of agreement

The court's objective is typically to prevent irreversible harm before trial.

The Legal Test: American Cyanamid Principles

For interim injunctions, courts apply the principles from American Cyanamid Co v Ethicon Ltd. These are flexible guidelines rather than strict rules:

1. Serious issue to be tried

The claimant must show the case is not frivolous or vexatious and raises a real legal dispute.

2. Adequacy of damages

The court considers whether damages would be an adequate remedy for either party.

• If damages are sufficient, an injunction is usually refused.
• If damages are insufficient (for example, loss of reputation or confidential information), an injunction is more likely.

3. Balance of convenience

The court assesses which outcome causes less injustice until trial.

Factors may include:

• Preservation of the status quo
• Risk of irreversible harm
• Commercial impact on both parties

4. Undertaking in damages

The applicant usually must promise to compensate the defendant if the injunction is later found to have been wrongly granted.

Types of Injunctions in Contract Disputes

Prohibitory injunction

Prevents a party from doing something, such as breaching a non-compete clause.

Mandatory injunction

Requires a party to take positive steps, such as returning confidential documents or restoring performance under a contract. Courts apply stricter scrutiny due to its intrusive nature.

Interim injunction

A temporary order granted before trial.

Final injunction

A permanent order made after the court determines liability at trial.

Step-by-Step: How to Apply for an Injunction

Step 1: Pre-action considerations

Before applying, the claimant is generally expected to:

• Send a letter before action setting out the breach and requested relief
• Warn of intended injunction proceedings if urgent
• Consider alternative dispute resolution where appropriate

Urgency may justify proceeding without full pre-action steps.

Step 2: Issue the claim (if not already started)

An injunction can be sought:

• Within existing proceedings, or
• Before issuing a substantive claim (where urgency exists)

Where proceedings have not yet begun, the court may still grant interim relief provided a claim is issued promptly.

Step 3: Application under CPR Part 23

The application is made using:

• Application notice (Form N244)
• Draft order setting out the injunction terms
• Witness statement or affidavit evidence
• Supporting documents (contract, correspondence, proof of breach)

The evidence must set out why the injunction is necessary and urgent.

Step 4: Notice to the other party

The general rule is that the respondent must be given notice of the application and supporting documents before the hearing.

However, in urgent cases, the application may be made:

• On notice (standard approach)
• Without notice (exceptional circumstances, such as risk of evidence destruction or immediate harm)

Without notice applications require full disclosure of all relevant facts, including those adverse to the applicant.

Step 5: Court hearing

The court will usually hear applications in the High Court or County Court depending on value and complexity.

At the hearing, the judge will consider:

• Legal merits under the American Cyanamid test
• Evidence of breach and urgency
• Balance of convenience
• Draft terms of the injunction

Hearings for urgent applications can be listed at short notice.

Step 6: Undertaking and enforcement

If granted, the claimant must provide:

• An undertaking in damages (financial guarantee)
• Compliance with the terms of the order

The order will usually contain a penal notice, meaning breach may result in contempt of court proceedings.

Time Sensitivity and Urgency

Injunction applications are often time-critical. Delay can:

• Weaken the case for urgency
• Reduce likelihood of relief
• Suggest damages would be adequate

Courts expect applicants to act promptly once aware of a breach.

Risks and Limitations

Applying for an injunction carries several risks:

• Financial liability under the undertaking in damages
• Legal costs exposure if the application fails
• Potentially negative impact on the underlying dispute
• Risk of refusal if damages are considered adequate

The court retains broad discretion and may refuse relief even where breach is proven.

Variation and Discharge

An injunction can later be:

• Varied (changed)
• Discharged (cancelled)
• Stayed pending appeal

This may occur if circumstances change or if the court finds the order was wrongly made.

Common Questions

Can an injunction enforce a contract?

Yes, but courts distinguish between prohibitory relief and specific performance. Mandatory injunctions may indirectly require performance of contractual obligations.

Do I need a solicitor?

Injunction applications are complex and evidence-heavy. While individuals can apply, they are typically handled by solicitors due to procedural and evidential requirements.

How quickly can an injunction be granted?

In urgent cases, interim injunctions can be granted within days or even hours, depending on the risk of harm and court availability.

Key Takeaways

Applying for an injunction in a contract dispute involves a formal court application supported by evidence showing urgency, breach, and insufficient remedy in damages. The court applies the American Cyanamid principles to decide whether interim relief is justified, balancing fairness and risk of harm. The procedure is governed by CPR Parts 23 and 25 and typically requires a draft order, witness statement evidence, and an undertaking in damages. Injunctions are powerful but discretionary remedies, and courts scrutinise them closely due to their immediate and often restrictive impact.
