Legal Case Summary
Cassidy v Daily Mirror Newspapers Ltd [1929] 2 KB 331
Libel; husband and wife; statement for per se defamatory
Facts
The claimant was known as the lawfully wedded wife of a famous race-horse owner and former General of the Mexican Army. The claimant and her husband lived separately but he often visited her at her workplace. The defendant newspaper published a photograph of the claimant’s husband with a woman labelled as Miss X, to whom – as alleged by the attached article – he was engaged.
Issues
The claimant argued that the publication caused damage to her in that it was intended to imply that her husband was living with her immorally. The defendants denied any such intention and even the possibility of their publication having such a meaning. The defendants refused to admit, even after seeing evidence thereof, that the claimant was married to the subject of the publication. The trial judge found that in the circumstances of this case, the publication could be seen as having a defamatory meaning. He directed the jury that what mattered was the perception of the reasonably minded person who knew the circumstances of the case. The jury found in favour of the claimant.
Decision / Outcome
The Court of Appeal held, affirming the lower court’s decision, that the publication in question was capable of constituting defamation. It found that the jury was right to find that the publication made the reasonably minded person believe that the claimant’s moral character was questionable.

This article accurately summarises the facts, issues, and outcome of Cassidy v Daily Mirror Newspapers Ltd [1929] 2 KB 331, a leading case in the law of defamation concerning innuendo and the reasonable reader test. The case remains good law and continues to be cited in English defamation proceedings and academic materials as an authority on false innuendo (extrinsic facts known to some readers giving an otherwise innocent statement a defamatory meaning).
Readers should note that defamation law in England and Wales has since been significantly reformed by the Defamation Act 2013, which introduced, among other things, a serious harm threshold (s.1) and modified the role of juries in defamation trials (s.11, reversing the presumption in favour of jury trial). These reforms do not affect the historical authority of this case on the law of innuendo, but students should consider how some of its practical consequences might differ under the current statutory framework. The 2013 Act does not apply to Scotland, where defamation law developed separately and was reformed by the Defamation and Malicious Publication (Scotland) Act 2021.
