SLAPP Suits in the UK: How the Law Protects Against Strategic Lawsuits

Strategic Lawsuits Against Public Participation — known as SLAPP suits — use the threat of expensive defamation litigation to silence journalists, activists, whistleblowers, and ordinary citizens who speak out on matters of public interest. The UK is now developing specific legal protections against this abuse of the legal system.

What Is a SLAPP Suit?

A SLAPP suit is a defamation (or related) claim brought not to vindicate a genuine reputation interest, but to intimidate the defendant into silence. The claimant's real objective is not to win in court but to impose such enormous legal costs and stress on the defendant that they withdraw their statements, delete their publications, and refrain from future criticism.

Typical characteristics of a SLAPP suit include:

• A wealthy or powerful claimant suing a less resourced defendant
• The subject matter involves public interest or criticism of the claimant's conduct
• The claim appears designed to silence rather than to seek genuine legal remedy
• Disproportionate costs — the legal costs dwarf any realistic damages recovery
• Aggressive litigation tactics designed to exhaust the defendant financially

UK Anti-SLAPP Protections

The UK has been developing anti-SLAPP measures following high-profile cases involving Russian oligarchs, corporate entities, and political figures using London courts to silence critics:

The Early Dismissal Mechanism

The Strategic Litigation Against Public Participation Bill introduces an early dismissal mechanism. Under this procedure:

1. The defendant applies for early dismissal on the grounds that the claim is a SLAPP
2. The court considers whether the claim has sufficient merit to proceed and whether it constitutes an abuse of process
3. If the court finds the claim is a SLAPP, it is dismissed at an early stage — before the defendant incurs the costs of full trial preparation

Existing Protections

Even before specific anti-SLAPP legislation, UK law provides some protections:

• Abuse of process — the court can strike out claims that are an abuse of the court's process
• Section 4 public interest defence — protects statements on matters of public interest where the defendant reasonably believed publication was justified
• Costs management — courts can impose costs caps and make adverse costs orders against claimants who bring disproportionate claims
• Qualified privilege — protects certain categories of communication made on occasions of duty or interest

How to Recognise a SLAPP Suit

If you've received a legal threat or claim that you suspect may be a SLAPP, consider these indicators:

• The claimant is significantly wealthier or more powerful than you
• Your statement concerned a matter of genuine public interest (corruption, safety, etc.)
• The legal letters are aggressive and disproportionate to the alleged harm
• The claimant seeks injunctive relief (silence) rather than just damages
• The claimant's lawyers demand you delete all content and sign a confidentiality agreement
• Similar threats have been made against other people who criticised the claimant

What to Do If You're Targeted

1. Do not panic or immediately comply — many SLAPP threats are never followed through
2. Seek specialist legal advice immediately — SLAPP defence requires specialist expertise
3. Preserve all evidence of the original publication and the legal threats
4. Contact press freedom organisations — groups like the Media Defence Fund and Index on Censorship support SLAPP targets
5. Consider applying for early dismissal if the claim progresses to court

• The UK is developing specific anti-SLAPP legislation with an early dismissal mechanism
• Existing protections include abuse of process, the public interest defence, and costs management
