Cross-Border Defamation: Enforcing UK Judgments Abroad

The internet has made cross-border defamation commonplace — content published in one country can damage reputations worldwide. While UK courts are well-equipped to hear international defamation claims, enforcing a judgment against a defendant based overseas presents significant practical and legal challenges.

Jurisdiction: Can UK Courts Hear the Claim?

Before worrying about enforcement, the first question is whether the English courts have jurisdiction. Under the Defamation Act 2013, section 9 provides that a court does not have jurisdiction to hear a defamation claim against a person not domiciled in the UK, an EU member state, or a Lugano Convention state unless satisfied that England and Wales is "clearly the most appropriate place" to bring the action.

This is a higher threshold than the pre-2013 position and was designed to prevent "libel tourism." However, where the claimant is UK-based, the defamatory content targets a UK audience, and the majority of the damage is suffered here, English courts will usually accept jurisdiction.

Enforcing UK Judgments Within Europe

Post-Brexit, enforcement within the EU is no longer governed by the Brussels Regulation (recast). UK judgments must now be enforced under:

• The Hague Convention on Choice of Court Agreements 2005 — applies where there was an exclusive jurisdiction clause, which is rare in defamation cases
• Bilateral treaties — the UK has limited bilateral enforcement treaties with certain countries
• National law of the enforcing state — in most EU countries, a UK judgment can be enforced through local court proceedings, but the defendant can raise fresh defences

The practical effect is that enforcement in EU member states has become more complex and expensive since Brexit. Each country's national rules must be assessed individually.

Enforcing Judgments in the United States

The US is notoriously difficult for enforcing foreign defamation judgments. The SPEECH Act 2010 (Securing the Protection of our Enduring and Established Constitutional Heritage) prevents US courts from enforcing foreign defamation judgments unless the foreign law provides at least as much free speech protection as the First Amendment.

Since UK defamation law places the burden of proving truth on the defendant (rather than requiring the claimant to prove falsity, as in the US), UK judgments almost never meet this threshold. Enforcement in the US is therefore practically impossible for most defamation judgments.

Enforcement in Commonwealth Countries

Many Commonwealth jurisdictions — including Australia, Canada, India, and Singapore — have more favourable enforcement regimes for UK judgments. Several of these countries have reciprocal enforcement legislation that allows UK judgments to be registered and enforced relatively straightforwardly.

However, enforcement still requires local legal proceedings, and the defendant may challenge recognition on grounds such as natural justice violations, fraud, or public policy.

Practical Enforcement Strategies

Given the challenges of cross-border enforcement, practical strategies include:

• Identify enforceable assets before commencing proceedings — there is no point obtaining a judgment if the defendant has no assets in a jurisdiction where enforcement is feasible
• Consider freezing orders — a worldwide freezing injunction can prevent the defendant from dissipating assets before judgment
• Use platform takedown — even if the defendant is judgment-proof, a court order can compel platforms to remove content globally
• Negotiate settlement — the threat of proceedings in the UK (with its claimant-friendly reputation system) can be a powerful negotiating tool

Key Takeaways

• UK courts can hear cross-border defamation claims but must be "clearly the most appropriate" forum
• Post-Brexit enforcement in the EU has become more complex
• US enforcement is practically impossible due to the SPEECH Act
• Commonwealth jurisdictions generally have more favourable enforcement regimes
• Asset identification and freezing orders are critical tactical considerations
