On January 11, 2024, the United Kingdom (U.K.) Supreme Court rendered its judgment in Paul v Royal Wolverhampton NHS Trust , restricting the circumstances in which “secondary victims” can successfully claim for damages in clinical negligence cases. This ruling has provided welcome clarity regarding the scope of negligently caused “pure” psychiatric illness claims, but the judgment may well prove controversial. In this article, I trace the facts and opinion from the majority and also discuss an important dissenting opinion. I then reflect on what the ruling means for psychiatric illness claims by secondary victims, and more broadly on the implications for clinical negligence law. I suggest that while much-needed clarity has been injected in this area of the law, it is difficult, reading the majority of the Supreme Court’s emphasis on the restricted scope of a medical practitioner’s duty, to envision a scenario in which secondary victim could ever succeed in a clinical negligence context.
