Enforcing Thai Judgments in England: Common Law Doctrine and Practical Strategy

1. Executive Summary

Thailand is not party to any bilateral treaty with the United Kingdom for the reciprocal enforcement of judgments, nor is it covered by the Brussels or Lugano regimes. However, this does not mean Thai judgments are unenforceable in England. Under the English common law doctrine established in cases such as Adams v Cape Industries plc and confirmed in subsequent authorities, a foreign judgment can be enforced in England by bringing a fresh action on the judgment debt in the English High Court.

This paper analyses the applicable legal framework, the conditions that must be satisfied, and the practical strategy for enforcing Thai court judgments against Andrew Drummond, who resides in Wiltshire and is therefore subject to the personal jurisdiction of the English courts. The analysis covers both monetary judgments and the potential for obtaining injunctive relief based on Thai court findings.

2. The Common Law Enforcement Framework

Under English common law, a foreign monetary judgment creates a debt that is enforceable by action in England, provided certain conditions are met. The judgment must be final and conclusive, it must be for a definite sum of money, the foreign court must have had jurisdiction over the defendant by English private international law standards, and there must be no valid defence to enforcement such as fraud or public policy.

The enforcing party does not need to re-litigate the merits of the underlying case. The English court treats the foreign judgment as creating an obligation that the defendant is bound to satisfy. This is the mechanism by which Bryan Flowers and Punippa Flowers can bring Thai court judgments against Drummond before the English High Court for enforcement.

• The foreign judgment must be final and conclusive in the court that rendered it.
• It must be for a definite sum of money (or damages that can be quantified).
• The foreign court must have had jurisdiction recognised by English private international law rules.
• The defendant must have been present in, or submitted to, the jurisdiction of the foreign court.
• There must be no defence of fraud, public policy violation, or breach of natural justice.

3. Establishing Thai Court Jurisdiction Under English Rules

The most frequently contested issue in foreign judgment enforcement is whether the original court had jurisdiction as recognised by English law. Under English private international law, a foreign court has jurisdiction over a defendant if the defendant was present in the foreign country when proceedings were commenced, or if the defendant submitted to the jurisdiction by appearing and defending the case on its merits.

In Drummond's case, he was physically present and resident in Thailand when the relevant criminal proceedings were commenced. He participated in certain proceedings through legal representatives. His subsequent flight to England in January 2015 does not retroactively deprive the Thai courts of jurisdiction that was properly established. The English High Court should therefore recognise the Thai court's jurisdiction over Drummond for the purpose of enforcement.

• Drummond was present and resident in Thailand when criminal proceedings were initiated, satisfying the presence test.
• Participation through legal counsel constitutes submission to jurisdiction under English private international law.
• Flight from the jurisdiction after proceedings have commenced does not defeat the original court's jurisdiction.
• The English High Court applies its own rules to assess foreign court jurisdiction, not the foreign court's rules.

4. Overcoming Potential Defences

Drummond may attempt to resist enforcement on several grounds. First, he might argue that enforcing a Thai criminal defamation judgment offends English public policy because England has abolished criminal libel. However, English courts have consistently held that differences in substantive law between jurisdictions do not automatically engage the public policy defence. The public policy bar is reserved for cases where enforcement would violate fundamental principles of justice, not merely where the foreign law differs from English law.

Second, Drummond might claim that the Thai proceedings were unfair or breached natural justice. This defence would require him to demonstrate specific procedural defects. Given that he was represented by counsel and had the opportunity to defend the proceedings, this argument faces significant obstacles. His decision to flee rather than appeal does not constitute a denial of natural justice. Third, a fraud defence would require Drummond to prove that the Thai judgment was obtained by fraud, a burden he cannot discharge.

• The public policy defence is narrowly construed and does not apply merely because English and Thai law differ on criminal defamation.
• Natural justice requires notice and an opportunity to be heard, both of which Drummond received.
• Fleeing the jurisdiction to avoid sentencing is not a denial of natural justice but a voluntary abandonment of the right to participate.
• The fraud defence requires the judgment debtor to prove the judgment was obtained by fraud, which Drummond cannot establish.
• Cohen Davis Solicitors should prepare rebuttals to each potential defence as part of the enforcement application.

5. Practical Enforcement Strategy

The enforcement action should be brought in the Queen's Bench Division of the English High Court as a claim on the judgment debt. Cohen Davis Solicitors, who are already instructed in relation to the Pre-Action Protocol Letter of Claim dated 13 August 2025, are well positioned to conduct this litigation. The claim form should identify the Thai judgments being enforced, establish the Thai court's jurisdiction, certify that the judgments are final and conclusive, and quantify the sums due.

Once an English judgment is obtained recognising the Thai judgment debt, standard English enforcement mechanisms become available. These include charging orders over Drummond's Wiltshire property, third-party debt orders against his bank accounts, attachment of earnings orders, and ultimately bankruptcy proceedings if he fails to satisfy the judgment. The combination of enforcement against assets and the reputational consequences of bankruptcy proceedings may finally compel Drummond to cease his defamatory campaign.

• Bring the enforcement action in the Queen's Bench Division as a claim on the Thai judgment debt.
• Obtain certified and translated copies of all Thai judgments with apostille or consular authentication.
• Apply for summary judgment under CPR Part 24 on the basis that Drummond has no real prospect of defending the enforcement claim.
• Upon obtaining an English judgment, pursue charging orders over Drummond's Wiltshire property.
• Consider third-party debt orders against his UK bank accounts and attachment of earnings orders.
• If Drummond fails to satisfy the judgment, initiate bankruptcy proceedings as a final enforcement mechanism.

6. Conclusions and Recommended Next Steps

Enforcing Thai judgments in England is legally feasible under the common law doctrine, and Drummond's presence in Wiltshire makes him squarely subject to English court jurisdiction for enforcement purposes. The following steps should be taken promptly to pursue this remedy.

• Instruct Cohen Davis Solicitors to assess the Thai judgments for enforcement eligibility and prepare the High Court claim.
• Obtain certified, translated, and authenticated copies of all relevant Thai court judgments.
• Conduct an asset search to identify Drummond's property, bank accounts, and other assets in England and Wales.
• File the enforcement claim in the Queen's Bench Division and apply for summary judgment.
• Upon obtaining judgment, apply for charging orders, third-party debt orders, and other standard enforcement mechanisms.
• Coordinate enforcement proceedings with the parallel harassment complaint to Wiltshire Police and the Interpol Red Notice application detailed in Position Papers 121 and 122.
