This concise treatise on defamation is both lucid and comprehensive. Previous editions have been cited frequently by first instance and appellate courts. The fully updated fourth edition considers the very significant changes to the law of libel and slander brought about by the Defamation Act 2013, and the law's continuing attempts to meet the challenges posed by publications on the internet and via social media. Where the law is uncertain, the authors suggest a solution which in their view accords with principle. In recognition of the fact that, increasingly, practitioners are called upon to advise on related causes of action, the book includes chapters on malicious falsehood and misuse of private information and has been expanded, in the fourth edition, to address harassment and data protection. This leading authority on defamation law and related areas will be an essential addition to the library of all practitioners specialising in these fields, as well as students and generalists who require a clear overview of the subject.
