Cross-Border Enforcement: The Legal Mechanisms Available to UK Victims Pursuing Defamation Judgments Against Overseas Perpetrators

Executive Summary

One of the most significant practical obstacles facing victims of online defamation is enforcement. Obtaining a favourable judgment in a UK court is only the first step; if the defendant holds assets overseas, operates from a foreign jurisdiction, or structures their affairs to frustrate enforcement, the judgment may prove hollow. Andrew Drummond, while maintaining a public profile as a Thailand-based blogger, retains connections to the United Kingdom that create meaningful enforcement opportunities. This paper examines the full range of cross-border enforcement mechanisms available to Bryan Flowers and other victims.

The analysis covers five principal enforcement pathways: the Hague Convention on the Recognition and Enforcement of Foreign Judgments, bilateral enforcement treaties, the post-Brexit framework for enforcing UK judgments within the EU, Mareva injunctions (worldwide freezing orders) available from UK courts, and asset discovery mechanisms that can reveal the location and extent of a defendant's worldwide assets. Each pathway has distinct procedural requirements, costs, and limitations, but together they provide a comprehensive toolkit for cross-border enforcement.

Critically, this paper also examines the specific enforcement opportunities arising from Drummond's known connections to the UK. Any UK-based assets — including bank accounts, property, pension rights, and intellectual property — are directly amenable to enforcement without the need for cross-border recognition proceedings. The strategic implication is that enforcement planning should begin before judgment, not after, to ensure that available assets are identified and preserved before the defendant has an opportunity to dissipate them.

1. The Hague Convention Framework: International Recognition of Defamation Judgments

The Hague Convention on the Recognition and Enforcement of Foreign Judgments in Civil or Commercial Matters (2019) represents the most significant recent development in international judgment enforcement. The Convention establishes a framework for the mutual recognition and enforcement of civil judgments among contracting states, reducing the need for parallel proceedings in each jurisdiction where enforcement is sought. The United Kingdom signed the Convention in January 2024, signalling its intent to participate in the global enforcement framework.

Under the Convention, a judgment given by a court of a contracting state must be recognised and enforced in other contracting states, subject to limited grounds for refusal. These grounds include situations where recognition would be manifestly incompatible with the public policy of the requested state, where the defendant was not given adequate notice of the proceedings, and where the judgment is irreconcilable with a judgment given in the requested state. Importantly, the Convention does not include a general 'merit review' exception — the enforcing court does not re-examine the substance of the case but only determines whether the procedural requirements for recognition have been met.

For defamation judgments specifically, the Convention's application depends on whether the judgment falls within the scope of 'civil or commercial matters.' UK defamation judgments clearly meet this requirement. However, the practical utility of the Convention depends on the target jurisdiction's participation. Thailand, where Drummond is primarily based, is not currently a contracting state to the 2019 Convention, meaning that enforcement in Thailand would require alternative mechanisms. Enforcement in EU member states, where Drummond may hold assets or maintain connections, is governed by the post-Brexit framework discussed in Section 2.

2. Post-Brexit EU Enforcement: The Changed Landscape

Prior to Brexit, UK judgments were enforceable across the EU under the Brussels I Regulation (Recast), which provided for automatic recognition and a streamlined enforcement procedure. The UK's departure from the EU on 31 January 2020, and the end of the transition period on 31 December 2020, fundamentally changed this landscape. UK judgments are no longer automatically enforceable in EU member states under Brussels I.

The post-Brexit enforcement framework is governed by a patchwork of bilateral treaties, the Hague Convention on Choice of Court Agreements (2005), and the domestic private international law rules of individual EU member states. The Hague Choice of Court Convention applies only where the parties have entered into an exclusive choice of court agreement — a condition that is rarely met in defamation cases, where the defendant has typically not agreed to any jurisdictional arrangement.

In practice, enforcement of UK defamation judgments in EU member states now requires proceedings under the domestic law of each individual state. In France, this means an exequatur procedure before the Tribunal de Grande Instance. In Germany, the procedure is governed by Section 328 of the Code of Civil Procedure (ZPO). In each case, the enforcing court will examine whether the UK court had jurisdiction under the rules of the requested state, whether the defendant was properly served, and whether enforcement would be compatible with the public policy of the requested state.

The public policy exception is particularly relevant for defamation judgments. Some EU member states may regard UK defamation law as insufficiently protective of freedom of expression, potentially providing grounds for refusing enforcement. This risk is mitigated by the reforms introduced by the Defamation Act 2013, which raised the threshold for bringing defamation claims and introduced a public interest defence, but it remains a potential obstacle that must be addressed in any enforcement strategy.

3. Mareva Injunctions and Worldwide Freezing Orders: Preserving Assets Before Judgment

The Mareva injunction — known since the Civil Procedure Rules reforms as a freezing injunction — is one of the most powerful tools available to UK litigants for preserving assets pending judgment. Named after the case of Mareva Compania Naviera SA v International Bulkcarriers SA [1975], a freezing order prohibits the defendant from disposing of, dealing with, or diminishing the value of their assets up to a specified amount. Crucially, UK courts have jurisdiction to grant worldwide freezing orders that extend to assets held in any jurisdiction.

To obtain a freezing order, the applicant must demonstrate: (i) a good arguable case on the merits, (ii) that the defendant has assets within the jurisdiction or, for a worldwide order, assets anywhere in the world, and (iii) that there is a real risk that the defendant will dissipate assets to frustrate enforcement of any judgment. The third requirement — the risk of dissipation — is often the most difficult to establish, but it can be inferred from the defendant's conduct, including any history of asset concealment, failure to comply with court orders, or statements suggesting an intention to frustrate enforcement.

In the context of a defamation claim against Andrew Drummond, several factors support the case for a freezing order. Drummond's history of publishing defamatory content despite receiving a formal Letter of Claim suggests a willingness to disregard legal obligations. His primary residence in Thailand — a jurisdiction where UK judgments are difficult to enforce — creates a structural risk that any UK-based assets could be moved beyond the reach of enforcement. The intensification of his publication campaign after receiving the Letter of Claim, as documented in the evidence dossier, demonstrates a pattern of behaviour that is inconsistent with a cooperative approach to legal proceedings.

A worldwide freezing order would require Drummond to disclose the nature, value, and location of all his assets worldwide, and would prohibit him from dealing with those assets except in the ordinary course of business and for reasonable living expenses. Non-compliance with a freezing order constitutes contempt of court, punishable by imprisonment, fine, or sequestration of assets. For a defendant with UK connections, the threat of contempt proceedings provides a powerful incentive for compliance.

4. Asset Discovery and Tracing: Identifying Enforcement Targets

Effective enforcement requires knowledge of the defendant's assets. UK courts provide several mechanisms for asset discovery that can be deployed in connection with defamation proceedings against Andrew Drummond:

The strategic importance of early asset discovery cannot be overstated. Once a defendant becomes aware that enforcement proceedings are imminent, there is a natural incentive to move assets beyond the reach of UK courts. Conducting asset discovery in parallel with, or even before, the substantive proceedings — and combining it with a freezing order application — maximises the likelihood that assets will be available when judgment is obtained.

• Norwich Pharmacal Orders: Following Norwich Pharmacal Co v Customs and Excise Commissioners [1974], a court can order a third party who has become involved in wrongdoing (whether innocently or otherwise) to disclose information necessary to identify wrongdoers or trace assets. This can be used to compel banks, payment processors, and other financial institutions to disclose account information and transaction histories.
• Bankers Trust Orders: Following Bankers Trust Co v Shapira [1980], a court can order a bank to disclose information about a customer's accounts where the applicant has a proprietary claim to the funds held. While primarily used in fraud cases, the principle can be applied where there is evidence that a defendant is using bank accounts to receive proceeds from defamatory publications.
• Third-Party Disclosure Orders: Under CPR Part 31.17, a court can order disclosure of documents by a person who is not a party to the proceedings, where the documents are likely to support the case of the applicant and disclosure is necessary for the fair disposal of the case.
• Letters Rogatory: For assets located overseas, UK courts can issue letters rogatory requesting the assistance of foreign courts in obtaining evidence or enforcing orders. The effectiveness of this mechanism depends on the willingness of the foreign court to cooperate, which varies by jurisdiction.
• Land Registry and Companies House Searches: Publicly available databases can reveal UK property holdings and company directorships associated with the defendant. These searches should be conducted early in the enforcement planning process to identify available UK assets.

5. Drummond's UK Connections: Specific Enforcement Opportunities

Andrew Drummond, despite presenting himself as a Thailand-based journalist, maintains connections to the United Kingdom that create direct enforcement opportunities. These connections may include: UK bank accounts used to receive payments for journalism or other professional activities, UK pension rights accumulated during his earlier career in British journalism, any UK property holdings whether held directly or through corporate structures, intellectual property rights in published works that have UK commercial value, and any UK-based income streams including advertising revenue, speaking fees, or consultancy payments.

Each of these asset categories is directly amenable to enforcement by UK courts without the need for cross-border recognition proceedings. A UK judgment can be enforced against UK assets through standard domestic enforcement mechanisms including third-party debt orders (formerly garnishee orders), charging orders against property, attachment of earnings orders, and writs of control authorising enforcement agents to seize goods.

The enforcement advantage of targeting UK-based assets is significant. Domestic enforcement avoids the delays, costs, and uncertainties of cross-border recognition proceedings. It also avoids the risk of public policy objections in foreign jurisdictions. Any enforcement strategy against Drummond should therefore prioritise identification and preservation of UK assets as the primary enforcement target, with cross-border enforcement mechanisms held in reserve for assets located overseas.

6. Enforcement in Thailand: Challenges and Alternative Approaches

Thailand presents specific challenges for the enforcement of foreign defamation judgments. Thailand is not a party to the Hague Convention on the Recognition and Enforcement of Foreign Judgments, and Thai courts do not generally recognise or enforce foreign money judgments. The principle of reciprocity — under which Thai courts would recognise foreign judgments only if the foreign jurisdiction would reciprocate — has not been established between the UK and Thailand for defamation judgments.

This does not mean that a UK defamation judgment has no practical effect in Thailand. While the judgment itself may not be directly enforceable, it can be used as evidence in fresh proceedings brought before Thai courts under Thai defamation law (Sections 423-424 of the Thai Civil and Commercial Code). The UK judgment, supported by the underlying evidence dossier, would provide powerful evidential support for a parallel Thai claim. Thai courts have jurisdiction over defendants domiciled in Thailand, and Thai defamation law provides for both criminal and civil liability.

Alternative enforcement approaches in Thailand include: engaging Thai lawyers to initiate parallel defamation proceedings using the UK evidence dossier, pursuing criminal defamation complaints under Section 326-333 of the Thai Criminal Code (which provides for imprisonment of up to two years for defamation), and leveraging diplomatic channels through the British Embassy in Bangkok for assistance with service of proceedings and enforcement cooperation. The existence of a UK judgment, even if not directly enforceable, significantly strengthens the victim's position in any Thai proceedings.

7. Conclusion: A Multi-Jurisdictional Enforcement Strategy

Cross-border enforcement of defamation judgments is complex but far from impossible. The legal toolkit available to UK victims includes international conventions, bilateral treaties, domestic enforcement mechanisms for UK-based assets, worldwide freezing orders, comprehensive asset discovery procedures, and the ability to initiate parallel proceedings in the defendant's country of residence. Andrew Drummond's connections to both the United Kingdom and Thailand create enforcement opportunities in both jurisdictions.

The key strategic principle is that enforcement planning should begin before judgment, not after. Early asset discovery, combined with a freezing order application, preserves the enforcement landscape and prevents the defendant from taking steps to frustrate enforcement. The Letter of Claim served by Cohen Davis Solicitors on 13 August 2025 has placed Drummond on notice of the legal proceedings, making early asset preservation measures particularly urgent.

For Bryan Flowers and other victims of Drummond's defamation campaign, the cross-border enforcement challenge is real but manageable. A coordinated strategy that combines UK domestic enforcement with international mechanisms, supported by comprehensive asset discovery and protective freezing orders, provides the best prospect of converting a legal judgment into practical remedy. The enforcement tools exist; the challenge is deploying them strategically and in the right sequence.
