Sir James Dyson v MGN Limited

In a claim for libel based on an expression of opinion, the statutory defence of honest opinion permits reliance on additional facts closely connected with the indicated factual basis, provided that the indicated fact is true and the additional facts are substantially true. The defendant need not present a fair or balanced selection of facts. Contextual facts must be included only where their omission falsifies the supporting factual substratum or gives it a fundamentally different complexion. The objective question is whether an honest person, however prejudiced, irrational or obstinate, could have held the opinion. Under section 1 of the Defamation Act 2013, serious harm may be established inferentially, but the claimant must prove that the individual publication caused, or was likely to cause, serious harm.

The claimant sued the publisher of the Daily Mirror and The Mirror website over an article describing him as a hypocrite who had harmed the country and set a poor moral example after Dyson moved its head office to Singapore. Nicklin J had determined the meaning of the publication as defamatory opinion based on the claimant’s support for Brexit followed by the movement of Dyson’s global head office. The claimant challenged the truth and relevance of facts relied on for honest opinion, alleged that material context had been omitted, and contended that the publication caused serious harm under section 1 of the Defamation Act 2013. The central issues were whether the defendant could rely on connected facts beyond those expressly stated, whether an honest person could have held the opinion, and whether serious harm was proved.

1. Disposition. The claim was dismissed. The defendant established the defence of honest opinion and the claimant failed to prove serious harm.
2. Additional facts. Under section 3 of the Defamation Act 2013, the defendant could rely on all the pleaded facts concerning the movement of the electric-vehicle project and the restructuring of Dyson. The indicated fact remained essential: if it were false, the defence could not succeed. Where it was true, related and connected facts concerning the same corporate subject matter could be considered, even though they had not appeared in the article. The court treated the principles in Kemsley v Foot, Joseph v Spiller and Lowe v Associated Newspapers Ltd as supporting that approach (paras [88]-[108]).
3. Truth of the supporting facts. The decisions to manufacture the proposed electric vehicle in Singapore and to restructure Dyson through new Singaporean holding companies were substantially true. The restructuring entailed the movement of part of the business and the establishment in principle of a global headquarters in Singapore (paras [109]-[118]).
4. Context. The honest-opinion defence does not require a journalist to include every fact making the picture fairer or more balanced. An omitted fact matters only if it removes the underlying factual substratum or fundamentally alters the complexion of the facts stated. No such omission occurred here. The approach in Branson v Bower and the discussion in Gatley were adopted as correctly stating the narrow scope of any contextual obligation (paras [120]-[132]).
5. Objective honesty. The test is whether an honest commentator could have held the opinion, allowing for prejudice, exaggeration, irrationality and obstinacy. No clear or demonstrable economic harm was required. A loose symbolic connection between the relocation and perceived harm to the country was sufficient to keep the opinion within the wide margin permitted by honest opinion (paras [133]-[144]).
6. Serious harm. The court applied the principles in Lachaux v Independent Print Media Ltd and related authorities. The claimant’s inferential case was weakened by the light-hearted and rhetorical character of the article, the age and public prominence of the underlying events, the absence of evidence of financial or philanthropic harm, and the difficulty of attributing serious harm to this publication rather than to other publications. The claimant therefore failed to discharge the burden under section 1 (paras [145]-[159]).
