The Triumvirate of Extraordinary Remedies: Mareva, Norwich, and Anton Piller Orders

Mareva injunctions, Norwich orders, and Anton Piller orders stand outside the ordinary run of interlocutory remedies in Ontario litigation. Each embodies the court’s willingness to intervene where ordinary procedural tools would be inadequate.

Understanding Ontario’s Extraordinary Civil Remedies

In modern commercial litigation, parties sometimes face the challenge that a sophisticated or dishonest opponent may hide assets, destroy key evidence, or remain anonymous behind a wall of secrecy. While most disputes can be resolved using ordinary legal processes—pleadings, discovery, trial, and eventually judgment—Ontario courts have developed or recognized certain extraordinary remedies designed to prevent serious injustice or thwart underhanded tactics. Three such extraordinary tools are the Mareva injunction, the Norwich order, and the Anton Piller order. Each serves a distinct purpose, and each is considered drastic, exceptional, and subject to careful judicial scrutiny.

This post explores these remedies under Ontario law, discusses the tests and requirements for obtaining them, and provides guidance on when and why litigants might seek them. We will also address common pitfalls, practical considerations, and how clients can benefit from expert legal advice in these high-stakes scenarios.


The Mareva Injunction: Freezing Assets Before Judgment

Purpose and Nature

A Mareva injunction (also known as a freezing injunction) is an in personam order restraining a defendant from dissipating or removing assets from the jurisdiction before the plaintiff’s claim is resolved. The goal is not to provide the plaintiff with security or give it priority over other creditors, but rather to ensure that if the plaintiff ultimately wins at trial, the defendant’s assets remain available to satisfy the judgment. By preventing asset dissipation, a Mareva injunction protects the integrity of the court’s future orders and upholds public confidence in the legal system.

Mareva injunctions are extraordinary because they amount to a form of pre-judgment enforcement. Ordinarily, a litigant has no right to secure a defendant’s assets before proving its claim at trial. Courts in Ontario have long resisted this idea to avoid unfairness and maintain the balance of fairness and the presumption of innocence. Hence, Mareva injunctions are granted only in the clearest of cases, where there is compelling evidence that without the injunction, the defendant would frustrate any prospective judgment.

The Test for a Mareva Injunction

Ontario courts apply a multi-part test for granting a Mareva injunction:

  1. Strong Prima Facie Case on the Merits: The plaintiff must show a very strong case that it will likely succeed on the substantive claim. This threshold is higher than the standard for ordinary interlocutory injunctions. Evidence of fraud or dishonest behaviour by the defendant often supports meeting this criterion.

  2. Assets in the Jurisdiction (or a Basis for a Worldwide Order): Traditionally, Mareva injunctions freeze assets within Ontario. However, courts may now grant worldwide Mareva orders if the defendant has foreign assets and if the circumstances justify such extraordinary extraterritorial reach.

  3. Real Risk of Asset Dissipation: The plaintiff must provide convincing evidence that the defendant is likely to hide, remove, or dissipate assets to render any future judgment unenforceable. Conjecture is insufficient; concrete indicators of impending dissipation are required. This often involves showing that the defendant has secreted funds offshore, transferred assets to related parties for nominal consideration, or behaved fraudulently in the past.

  4. Balance of Convenience and Equities: The court weighs the potential harm to the plaintiff if the order is not granted against the harm to the defendant if it is. Because Mareva injunctions can be crippling, courts must ensure that the order is no more than necessary. Defendants are often permitted to use part of their assets for reasonable living or business expenses.

  5. Undertaking as to Damages: The plaintiff must undertake to indemnify the defendant if the injunction is found later to have been unnecessary, thus ensuring that the defendant is protected from unjust harm.

Practical Considerations

A Mareva injunction typically comes with a mandatory requirement that the defendant disclose all assets worldwide, identifying their nature, location, and value. Non-compliance can lead to a finding of contempt, punishable by fines or imprisonment. Plaintiffs and their counsel must be meticulous in their evidence, and defendants must be scrupulously honest and prompt in their disclosure.


The Norwich Order: Pre-Action Disclosure from Innocent Third Parties

Purpose and Nature

A Norwich order compels a third party—often an innocent participant who is unknowingly involved in the wrong—to disclose documents or information to assist the plaintiff in identifying a wrongdoer or substantiating a legal claim. Common targets include banks holding funds on behalf of a fraudster, or Internet Service Providers holding the identity details of an anonymous online defamer.

Norwich orders are used when the plaintiff cannot identify or locate the defendant, or lacks the evidence needed to frame a claim. By compelling a non-party to provide that information, the order helps ensure that justice is done. However, because it burdens an innocent non-party, courts grant Norwich orders sparingly. The applicant must show that there is a genuine need for the requested information and that it cannot be obtained elsewhere.

The Test for a Norwich Order

Ontario courts have developed several criteria for a Norwich order:

  1. A Bona Fide (Genuine) Claim: The applicant must have a real, legally recognizable claim against a known or unknown defendant. A Norwich order cannot be used as a fishing expedition to find a cause of action.

  2. Involvement of the Third Party: The third party must have been involved, albeit innocently, in the wrongdoing. For example, a bank that received misappropriated funds from a fraudster’s victim’s account is “mixed up” in the wrongdoing.

  3. No Other Practical Means to Obtain Information: The applicant must show that no other reasonable source of the evidence is available.

  4. Proportionality and Balancing of Interests: The court considers the non-party’s privacy, confidentiality, and costs. The order must be carefully tailored and the applicant often must pay the non-party’s reasonable expenses.

  5. Interests of Justice: Ultimately, the court’s inherent equitable jurisdiction guides the decision. If disclosure is essential to achieve justice, the court will lean toward granting the order.

Practical Considerations

Norwich orders frequently include confidentiality restrictions, allowing only the applicant’s counsel to review documents initially. The court may also limit the use of information obtained. Applicants should be ready to compensate the non-party for compliance costs and to explain why their request is narrowly focused.


The Anton Piller Order: Preserving Evidence Through a Civil Search Warrant

Purpose and Nature

An Anton Piller order is a pre-trial, ex parte injunction granting the plaintiff the right to enter a defendant’s premises (under supervision) to search for and preserve evidence at grave risk of destruction. Sometimes likened to a “civil search warrant,” it is, however, executed by independent supervising solicitors, not by the police. It aims to secure crucial evidence—documents, electronic records, prototypes, data—before the defendant can destroy them.

This is one of the most intrusive remedies in civil litigation. Courts only grant Anton Piller orders where there is a real threat that evidence vital to the case will vanish if the defendant learns of the litigation. Strict safeguards must be observed, including appointing an independent supervising solicitor, conducting the search during normal hours, and providing the defendant a reasonable opportunity to seek legal advice.

The Test for an Anton Piller Order

The criteria are stringent:

  1. Extremely Strong Prima Facie Case: Higher than a Mareva injunction’s standard, the plaintiff must show near certainty of success at trial.

  2. Very Serious Potential or Actual Harm: The evidence at stake must be central, and its destruction would cause irreparable harm to the plaintiff’s ability to prove its case.

  3. Convincing Evidence Defendant Possesses Incriminating Documents or Things: The plaintiff must show the defendant likely has evidence of wrongdoing and a propensity to destroy it if warned.

  4. No Less Drastic Remedy Available: The Anton Piller order must be a last resort, not a convenient option. Regular discovery, interim preservation orders, or undertakings from the defendant are insufficient.

  5. Undertakings and Safeguards: The order must contain strict protections for privilege and privacy. The seized materials are usually held in escrow by the supervising solicitor, and may not be handed to the plaintiff until privilege and relevance are determined.

Practical Considerations

Executing an Anton Piller order incorrectly can lead to severe consequences. If the plaintiff or its representatives act oppressively or exceed their authority, the order can be set aside and the plaintiff may be liable for damages. The plaintiff must ensure full and frank disclosure of all material facts when seeking the order ex parte.


Distinguishing the Remedies

While each remedy is extraordinary, they serve distinct purposes:

  • Mareva Injunction: Prevents dissipation of assets, ensuring that a successful plaintiff has something to collect upon at the end of the litigation.

  • Norwich Order: Enables the plaintiff to identify wrongdoers or obtain essential information held by a non-party, allowing the plaintiff to frame its claim properly.

  • Anton Piller Order: Ensures the preservation of critical evidence at immediate risk of destruction, safeguarding the integrity of the litigation process.

In some cases, a plaintiff might need more than one remedy. For instance, after obtaining a Mareva injunction to freeze assets, the plaintiff may need a Norwich order to identify additional recipients of funds or an Anton Piller order to secure evidence of fraudulent transactions. Courts, however, are mindful of the cumulative burden these orders impose and will grant them only if necessary and proportionate.


Compliance, Contempt, and Consequences

Each of these orders—Mareva, Norwich, Anton Piller—comes with a stern warning: disobedience can lead to contempt of court. Contempt is quasi-criminal, requiring proof beyond a reasonable doubt. Penalties can include fines, costs, and even imprisonment. Courts do not hesitate to enforce these orders rigorously because their effectiveness and the public’s faith in the judicial system depend on compliance.

For defendants, it is critical to understand that these orders, once granted, are not suggestions. They are binding court directions, backed by the court’s inherent jurisdiction to punish non-compliance. For plaintiffs, while these remedies are powerful, obtaining them improperly or executing them oppressively can backfire, leading to reversal and potential liability.


Engaging Experienced Counsel: The Key to Success

Securing a Mareva injunction, a Norwich order, or an Anton Piller order is not routine litigation work. The evidentiary burdens, the drafting complexities, and the need for careful execution demand experienced, specialized counsel. A seasoned lawyer can provide strategic advice, ensure full and frank disclosure to the court, draft the order’s terms precisely, and oversee proper execution. Similarly, defendants facing such orders should seek immediate legal advice to protect their rights, negotiate reasonable carve-outs, or contest unwarranted relief.

Conclusion

Mareva injunctions, Norwich orders, and Anton Piller orders stand outside the ordinary run of interlocutory remedies in Ontario litigation.

Plaintiffs must surmount high evidentiary hurdles; defendants retain robust protections and can challenge or vary the orders; and both sides must navigate these extraordinary measures with care and precision.

In essence, these remedies are extraordinary judicial responses to extraordinary facts. They ensure that justice is not thwarted by cunning wrongdoing or by the fortuitous disappearance of assets or evidence.

Offers to Settle in Ontario Litigation

Rule 49 offers to settle are a cornerstone of civil litigation in Ontario. They reflect a deliberate policy choice to encourage settlement and reduce the burden of trials. By attaching significant costs consequences to the rejection of reasonable offers, the rule compels litigants to weigh the risks of trial carefully.

Cross-Examination at Trial

Cross-examination is widely regarded as one of the most powerful tools in the trial process. It is not only a feature of the adversarial system but a defining characteristic that sets it apart from other legal traditions. Through cross-examination, the evidence of witnesses is tested for accuracy, reliability, and truthfulness. Where examination-in-chief allows a party to present its own case in an orderly fashion, cross-examination permits opposing counsel to probe, challenge, and, where appropriate, dismantle that account.
