This introductory chapter begins with a definition of tort law and the interests that tort law protects. To say that the law of tort protects an individual’s rights or interests does not mean that a claimant will succeed simply by showing that the defendant harmed them or infringed their rights. Tort law lays down a set of rules stating when exactly a harm or infringement of one’s interest will give rise to legal liability. The chapter discusses the disparate functions of tort law and illustrates them through the case of Woodroffe-Hedley v Cuthbertson . The chapter then explains the significance of the Human Rights Act 1998 for tort law.
