Injunctions in Business Disputes: A Guide for SMEs and Owner Managed Businesses

Urgent disputes between businesses can cause significant disruption, especially when there is a risk of assets being dissipated, confidential information being misused or further losses being incurred before the courts can reach a final decision. Injunctions are a powerful remedy that can be deployed to preserve the status quo and protect commercial interests. This guide explains when injunctions may be available, the different types, the legal test the courts apply and the practical steps for applicants and respondents. It is written for owner‑managed companies and small and medium‑sized enterprises (SMEs) operating under the law of England and Wales.

What is an injunction?

An injunction is a court order requiring a person or company either to do something (a mandatory injunction) or to refrain from doing something (a prohibitory injunction). Breach of an injunction amounts to contempt of court and can lead to fines, confiscation of assets or imprisonment. Injunctions may be granted interim, to preserve the position pending a trial, or final/perpetual as a permanent remedy after the case has been decided. Because they restrain conduct without a full trial, interim injunctions are considered draconian and the courts will grant them only where the claimant can show that damages or other remedies would be inadequate.

When injunctions are used

Injunctions are most often sought to prevent irreparable harm or preserve assets. Common scenarios include:

• Confidential information and trade secrets – preventing a former employee or competitor from disclosing confidential data or using know‑how gained in breach of non‑disclosure agreements or restrictive covenants.
• Intellectual property infringement – stopping the misuse of a business’s trade marks, patents or copyrights.
• Breach of contract – forcing a party to perform key obligations (such as delivering goods) or restraining them from acting in a way that would breach the agreement.
• Defamation and online harm – removing or preventing publication of defamatory statements about a business where damages would not adequately repair reputational damage.
• Asset preservation – preventing a debtor from dissipating assets before judgment (freezing injunctions) or searching premises to preserve evidence (search orders).
• Insolvency or winding‑up threats – restraining a creditor from presenting a winding‑up petition where there is a genuine dispute or counterclaim.

Types of injunction

The appropriate injunction depends on the circumstances. Common categories include:

Prohibitory injunction

Orders a party to stop doing something. The most common form of interim relief.

Typical uses:

• Stopping the misuse of confidential information or intellectual property.
• Enforcing restrictive covenants.
• Preventing publication of defamatory material.

Mandatory injunction

Orders a party to take positive steps, such as delivering goods or restoring property.

Typical uses:

• Forcing a supplier to fulfil a crucial delivery.
• Compelling a former employee to return confidential documents.

Freezing injunction (Mareva order)

Prevents a respondent from dealing with or dissipating assets within the jurisdiction (and sometimes worldwide) to preserve those assets for enforcement of a judgment.

Typical uses:

• Fraud claims.
• Cases involving suspected asset dissipation.
• Situations where a debtor is likely to transfer assets overseas.

Search order (Anton Piller order)

A search order permits the claimant’s lawyers, supervised by an independent solicitor, to enter the respondent’s premises to search for and seize evidence.

Typical uses:

• Situations where there is a real risk that documents or electronic data will be destroyed.

Springboard injunction

Prevents a former employee or competitor from gaining an unfair advantage by using confidential information or trade secrets.

Typical uses:

• Cases involving poaching of clients.
• Misuse of confidential business plans.

Privacy injunction

Restrains the publication of private or sensitive information and, in the case of a “super‑injunction”, even the existence of the injunction.

Typical uses:

• Protecting highly confidential commercial information or personal data.

Insolvency injunction

Prohibits the presentation or advertisement of a winding‑up petition where there is a genuine dispute about a debt.

Typical uses:

• Defending against inappropriate or abusive insolvency proceedings.

The legal test for interim injunctions

The courts apply a test derived from the House of Lords decision in American Cyanamid Co v Ethicon Ltd when deciding whether to grant an interim injunction. Applicants must persuade the court of the following:

• Serious issue to be tried – The claimant must show that there is a substantive legal claim which is neither frivolous nor vexatious. The court does not conduct a mini‑trial at the interim stage; it simply assesses whether there is a real issue that needs to be determined at trial.
• Adequacy of damages – The court asks whether an award of damages would adequately compensate the claimant if no injunction were granted. If monetary compensation would be sufficient, an injunction is unlikely. The court also considers whether the defendant could be adequately compensated by the claimant’s cross‑undertaking in damages if it later transpires that the injunction should not have been granted.
• Balance of convenience – The judge weighs the potential harm to each party. This involves assessing which party would suffer greater prejudice if the injunction were granted or refused. If the balance is even, the court will generally preserve the status quo.
• Full and frank disclosure – Applicants must disclose all material facts, including information that might undermine their case. Failure to do so can lead to the injunction being discharged and cost penalties.
• Just and convenient – Interim injunctions are discretionary. Courts consider factors such as delay in making the application and whether granting an injunction is fair and proportionate in the circumstances. Particular attention is paid to human rights considerations (for example, freedom of expression in defamation cases) which may require a higher threshold.

Cross‑undertaking in damages

A claimant seeking an injunction is normally required to provide a cross‑undertaking in damages, promising to compensate the respondent for losses suffered if it later emerges that the injunction should not have been granted. The court may ask for evidence that the claimant can satisfy this undertaking; sometimes security is required. The prospect of paying substantial damages is an important consideration when deciding whether to seek injunctive relief.

Applying for an injunction

Notice requirements

Applications for interim injunctions are usually made on notice, meaning the respondent is given notice of the application and a hearing date. In exceptional cases where giving notice would defeat the purpose of the order (for example, where assets may be moved or evidence destroyed), the court can grant an injunction without notice. Such applications must be supported by compelling evidence and full disclosure, and the court will list a return date for both parties to be heard.

Preparing the application

An application for an interim injunction must be filed in the court where the underlying claim will be heard. It should include:

• Application notice – Identifying the type of injunction sought and the orders requested.
• Supporting evidence – A witness statement or affidavit setting out all relevant facts, why an injunction is necessary, why damages would be inadequate and what harm will occur without urgent relief.
• Draft order – A proposed form of order detailing the precise terms of the injunction, including a penal notice warning of the consequences of breach.
• Skeleton argument – A concise outline of the legal arguments and authorities supporting the application.

The application should be supported by exhibits (such as contracts, correspondence and evidence of potential dissipation) and should be made promptly. Delay may indicate that the harm is not urgent and could lead the court to refuse relief.

Undertakings and enforcement

Injunction orders will contain a penal notice stating that breach may result in imprisonment, fines or seizure of assets. Respondents who wish to challenge or vary an injunction can apply to the court; in without‑notice cases this will usually be at the return hearing. Applicants are expected to comply with the duty of ongoing disclosure until the return date. Respondents may be able to negotiate undertakings (formal promises to the court) as an alternative to a contested injunction.

Costs and risks

Injunctions are expensive and risky. Applications often involve urgent hearings, barristers and significant court fees. If an applicant fails, they will usually be ordered to pay the respondent’s costs. Even if successful, they must provide a cross‑undertaking in damages. Breaching an injunction is contempt of court and can lead to imprisonment; directors may be personally liable for breaches by their company.

Injunctions should not be used as a tactical weapon. Courts disapprove of oppressive or unnecessary applications and may penalise claimants with indemnity costs. Before applying, businesses should consider whether damages, specific performance or alternative dispute resolution (ADR) might achieve their goals more proportionately. It is also prudent to explore whether the other party would agree to undertakings, which can avoid litigation and cost.

Alternatives to injunctions

In some situations, other remedies may be more appropriate:

• Damages – Monetary compensation may suffice where harm can be quantified.
• Specific performance – Requiring a party to carry out their contractual obligations.
• Undertakings – Parties can agree to undertakings to the court or to each other, avoiding contested proceedings.
• Alternative dispute resolution – Negotiation, mediation or arbitration can resolve disputes swiftly and confidentially, especially where ongoing relationships are important.

Preventive measures for business owners

Good planning reduces the need for emergency relief. Business owners should:

• Ensure commercial contracts include well‑drafted confidentiality clauses, restrictive covenants, dispute resolution clauses and governing law provisions.
• Register intellectual property and monitor for infringement.
• Maintain robust record‑keeping to support any urgent application.
• Act quickly when rights are threatened; delay can undermine the case for an injunction.
• Consider insurance or funding options to cover potential costs and cross‑undertakings.

Conclusion

Injunctions can be crucial in protecting a business from serious harm but they are an exceptional remedy. To succeed, applicants must demonstrate a serious issue to be tried, that damages alone are insufficient and that the balance of convenience favours granting relief. Owners of SMEs and family businesses should seek specialist advice as soon as they become aware of potential urgent harm. Acting promptly, preparing comprehensive evidence and understanding the risks will maximise the chances of obtaining or resisting, an injunction and safeguard commercial interests while minimising disruption and cost.
