Privacy vs Defamation: Which Legal Claim Is Right for You?

One of the most common questions we receive is: "I don't know whether I need a defamation claim or a privacy claim." It is a genuinely difficult question, and getting the answer wrong can mean pursuing the wrong remedy — or missing the right one. This guide explains the difference between defamation and misuse of private information (MPI), the scenarios where each applies, and the practical question of which route gives you the better outcome.

The Core Distinction: False vs Private

The starting point is deceptively simple. Defamation law deals with false statements that damage your reputation. Misuse of private information (MPI) deals with true information that you had a reasonable expectation of keeping private. The two torts are conceptually distinct, though in practice they often overlap.

• Defamation: Someone publishes a false statement that causes serious harm to your reputation
• Misuse of private information: Someone publishes true information about you that you had a reasonable expectation of keeping private (e.g. medical records, sexual behaviour, financial details, private correspondence)

The legal basis for MPI claims in English law is the developing common law tort recognised in Campbell v MGN Ltd [2004] UKHL 22, underpinned by Article 8 of the European Convention on Human Rights (right to respect for private and family life).

When Only Defamation Applies

Defamation is the appropriate claim where the information published about you is false and damaging to your reputation. You cannot bring an MPI claim for false information — the courts have confirmed that MPI protects genuinely private (and therefore true) information, not fabricated allegations.

Classic defamation scenarios include: false allegations of criminal conduct; false claims of professional incompetence or misconduct; fabricated sexual allegations; false statements that you are insolvent, dishonest, or have a contagious disease.

When Only MPI Applies

MPI is the appropriate claim where the information is true but private. If someone publishes accurate information that you had a reasonable expectation of keeping confidential, defamation is not available (truth is a complete defence to defamation under section 2 of the Defamation Act 2013). But you may have a strong MPI claim.

Classic MPI scenarios include: publication of medical records or diagnoses; disclosure of sexual orientation without consent; publication of private correspondence, voicemails, or messages; disclosure of financial information not in the public domain; publication of photographs taken in private settings.

When Both Claims Overlap

The two torts can coexist where the published material is partly false (giving rise to a defamation claim) and partly true but private (giving rise to an MPI claim). This is more common than many clients expect — a newspaper article or social media post may mix false defamatory allegations with true private details. In these cases, a skilled solicitor will assess both heads of claim simultaneously and pursue the most advantageous combination.

Which Route Gives Better Remedies?

The choice of claim affects the remedies available:

• Defamation: Focuses on vindicating reputation. The primary remedy is damages for reputational harm, plus an injunction restraining further publication and, under section 12 of the Defamation Act 2013, a court summary. Truth is a complete defence — so if the defendant can prove the statement is substantially true, the defamation claim fails.
• MPI: Focuses on privacy and autonomy. Remedies include injunctions (including pre-publication injunctions under Article 8), damages for distress and loss of control over private information, and account of profits. Crucially, truth is not a defence to MPI — the fact that information is accurate does not justify its publication if the privacy interest outweighs the public interest in disclosure.

In high-profile cases involving threatened media publication, the MPI route (with its pre-publication injunction mechanism) is often faster and more powerful than defamation, which is generally a post-publication remedy.

The Role of Article 8 ECHR and the Public Interest Balancing Exercise

In MPI cases, the court conducts a balancing exercise between Article 8 (right to private life) and Article 10 (freedom of expression). Public figures attract less protection for their public roles but retain strong privacy rights in relation to their private lives, health, and family. Private individuals attract correspondingly stronger protection. The defendant must demonstrate a genuine public interest in disclosure — not mere curiosity or entertainment value — to defeat an MPI claim.
