Defamation Counterclaims: Can You Sue Back?

When you are sued for defamation, you may wonder whether you can "sue back." In certain circumstances, a defendant can file a counterclaim — either for defamation by the claimant or on other grounds such as malicious prosecution or abuse of process. This guide explains when counterclaims are available and how they work.

When Can You Counterclaim for Defamation?

A counterclaim for defamation is available when the claimant has themselves made false and defamatory statements about the defendant. Common scenarios include:

• Mutual allegations — disputes where both parties have made damaging statements about each other (e.g., business partners accusing each other of fraud)
• Statements in the proceedings — while statements made in court proceedings are protected by absolute privilege, statements made outside proceedings (e.g., to the media, on social media, or to business contacts) are not
• The claim itself as publication — the Particulars of Claim are a public document once filed. If they contain false and defamatory allegations that go beyond what is necessary for the claim, they may be actionable

Malicious Prosecution and Abuse of Process

If the defamation claim against you was brought without merit and with an improper motive, you may have a claim for:

• Malicious prosecution — where the claimant brought the claim knowing it had no reasonable prospect of success and was motivated by malice. This is difficult to prove but can result in substantial damages
• Abuse of process — where the claimant is using the litigation process for an improper purpose (e.g., to silence legitimate criticism rather than to vindicate their reputation)

The courts are increasingly alert to SLAPP suits — strategic lawsuits designed to intimidate and silence critics.

How to File a Counterclaim

Procedurally, a counterclaim is filed alongside your Defence:

1. Include the counterclaim in the same document as your Defence (Part 20 of the Civil Procedure Rules)
2. Set out the defamatory statements made by the claimant
3. Explain the meaning you attribute to those statements
4. Demonstrate serious harm to your reputation
5. Specify the remedies you seek (damages, injunction, apology)

Strategic Considerations

Before filing a counterclaim, consider these strategic factors:

• Costs — a counterclaim increases the scope and cost of the litigation for both parties
• Escalation — counterclaims can entrench positions and make settlement more difficult
• Merits — a weak counterclaim can damage your credibility with the court
• Bargaining power — a strong counterclaim can encourage the claimant to settle or withdraw their claim
• Costs protection — if your counterclaim succeeds and the original claim fails, the claimant may be ordered to pay your costs for both

Costs Implications

The costs implications of a counterclaim can be significant:

• If both the claim and counterclaim succeed, the court will apportion costs based on the relative success of each party
• If the counterclaim fails, you may be ordered to pay the claimant's costs of defending it — in addition to any costs you owe on the original claim
• A well-judged Part 36 settlement offer can protect you from adverse costs consequences
