Vicarious liability is an emotive issue when it concerns the imposition of liability on a blameless party, in circumstances where someone else is in the wrong. It is a flexible doctrine which depends on public policy. Since Lister in 2002, the law has been undergoing fundamental change. The Supreme Court has decided several cases in the last six years: Armes, Mohamud, Cox, the Christian Brothers case. These and other leading authorities are reviewed. In Dubai Aluminium Co Ltd v Salaam [2002] UKHL 48 Lord Nicolls made reference to the infinite range of circumstances where the issue arises. The crucial feature, or features, either producing or negativing liability vary widely from one case, or type of case to the next. Essentially the court makes an evaluative judgement in each case, having regard to all the circumstances and, importantly, having regard also to the assistance provided by previous court decisions… This book seeks to provide a practical guide to the evolving policy considerations which underpin this doctrine in the law of negligence, and in intentional and reliance torts.
