 This entry examines philosophical accounts of tort law, distinguishing its obligations from other types of private legal obligation, and distinguishing its characteristic remedies from the punitive responses of the criminal law and from administrative regulation. It focuses exclusively on tort law within common law systems, that is, legal systems descended from English law, including Australia, Canada, New Zealand, Singapore, the United States. Other legal systems, originating in continental Europe, are usually described as “civilian” systems. They have detailed civil codes covering many of the same issues as the common law of torts. Some civilian systems share many doctrinal features with common-law system; others, particularly France, offer fundamentally different ways of dealing with the same set of interactions and the problems to which they give rise.
