In commercial litigation, one of the biggest concerns for claimants is the risk that a defendant might move or hide assets before a court judgment can be enforced. This fear becomes especially serious in cross-border disputes where money can be transferred quickly between jurisdictions. To address this problem, courts developed a powerful legal remedy known as the Mareva injunction. A central requirement for obtaining this freezing order is proving a good arguable case. Understanding what qualifies as a good arguable case in a Mareva injunction application is essential for lawyers, businesses, and anyone involved in high-value civil disputes.
What Is a Mareva Injunction?
Agave rise to what is now widely known as the Mareva injunction. This legal remedy allows a court to freeze a defendant’s assets temporarily to prevent them from being dissipated before a final judgment is delivered.
Today, the Mareva injunction is often referred to as a freezing order. It does not give the claimant ownership of the assets. Instead, it restricts the defendant from disposing of or dealing with assets in a way that would undermine the enforcement of a future judgment.
The Purpose of a Freezing Order
The primary purpose of a Mareva injunction is protective rather than punitive. Courts grant it to ensure that justice is not frustrated by the disappearance of assets. Without such an order, a successful claimant could win a case but find there is nothing left to enforce against.
Because a Mareva injunction is a serious and intrusive remedy, courts apply strict criteria before granting it. One of the most important requirements is demonstrating a good arguable case.
Meaning of a Good Arguable Case
The phrase good arguable case does not mean that the claimant must prove their claim fully at this stage. Instead, it requires the claimant to show that their claim is more than merely speculative or weak. The case must be strong enough to justify the court’s intervention.
In simple terms, a good arguable case means
- The claim has a solid legal basis.
- There is credible evidence supporting the allegations.
- The argument is stronger than a barely arguable claim.
Courts often describe it as a case that is better than 50 percent likely to succeed, though it does not require full proof.
Elements Required for a Mareva Injunction
To obtain a Mareva injunction, the applicant generally must establish several elements
- A good arguable case on the merits.
- A real risk of asset dissipation.
- Assets within the jurisdiction (or subject to the court’s reach).
- That it is just and convenient to grant the order.
Among these elements, the good arguable case requirement acts as the foundation. Without it, the application will likely fail.
Judicial Interpretation of Good Arguable Case
Higher Than a Serious Question
The standard for a good arguable case is higher than simply showing a serious issue to be tried. Courts demand a persuasive argument supported by evidence, not just allegations.
Not a Mini-Trial
Although the court examines the merits, it does not conduct a full trial during the injunction hearing. The purpose is to assess whether the claimant’s case is sufficiently strong to justify freezing assets.
Flexible but Structured
Judges exercise discretion, meaning the standard is flexible. However, they consistently require clarity, documentary support, and logical legal reasoning.
Evidence Supporting a Good Arguable Case
To meet the good arguable case threshold in a Mareva injunction application, claimants typically provide
- Contracts or written agreements.
- Financial records.
- Email communications.
- Witness statements.
- Bank transaction evidence.
The stronger and more organized the evidence, the more likely the court will be satisfied that the claim has real substance.
Risk of Dissipation and Its Connection
Even if a claimant establishes a good arguable case, the court will not automatically grant a Mareva injunction. There must also be a genuine risk that the defendant will dissipate assets.
Examples of risk factors include
- Past dishonest behavior.
- Transfer of funds to offshore accounts.
- Secrecy or refusal to provide financial disclosure.
- Rapid movement of assets after the dispute arises.
The good arguable case and risk of dissipation work together. A strong merits case strengthens the justification for freezing assets.
Cross-Border Applications
In international disputes, Mareva injunctions often extend beyond a single jurisdiction. Courts may grant worldwide freezing orders if the claimant can show a good arguable case and a real enforcement risk.
This is particularly relevant in cases involving multinational corporations or high-net-worth individuals with assets spread across several countries.
Defendant’s Perspective
From the defendant’s viewpoint, a Mareva injunction can significantly disrupt business operations. Therefore, defendants frequently challenge whether the claimant truly has a good arguable case.
They may argue that
- The legal claim is flawed.
- Key evidence is unreliable.
- The dispute is contractual but does not justify freezing assets.
If the court agrees that the claimant’s case is weak, the injunction will be refused or discharged.
Undertaking in Damages
Because a Mareva injunction is powerful, courts require claimants to provide an undertaking in damages. This means the claimant promises to compensate the defendant if it later turns out the injunction should not have been granted.
This safeguard reinforces the need for a genuine good arguable case before seeking such relief.
Practical Importance in Commercial Litigation
The concept of a good arguable case in Mareva injunction proceedings plays a crucial role in modern commercial law. Businesses rely on freezing orders to secure potential recovery in cases involving fraud, breach of contract, or misappropriation of funds.
At the same time, courts carefully balance fairness and urgency. They avoid granting freezing orders lightly because of the serious consequences involved.
Recent Developments and Trends
Courts continue to refine the interpretation of good arguable case, especially in complex financial disputes. Digital assets, cryptocurrency holdings, and cross-border banking have added new challenges to asset-tracing and enforcement.
Despite evolving financial systems, the fundamental principle remains the same a claimant must demonstrate a strong, credible legal claim before assets can be frozen.
The requirement of a good arguable case is central to obtaining a Mareva injunction. It ensures that freezing orders are granted only when there is a solid legal foundation and credible supporting evidence. This standard protects defendants from unjustified interference while safeguarding claimants from the risk of asset dissipation.
In commercial disputes where significant sums are at stake, understanding the meaning and application of a good arguable case can determine whether assets remain available for enforcement. By maintaining a careful balance between urgency and fairness, courts uphold both the integrity of the legal process and the effectiveness of civil remedies.
