The leading Spanish language treatise on the law on torts has now been translated into English, making it accessible to jurists, scholars and practitioners throughout the world. It addresses the central analytical questions in modern tort theory by reference to first principles, explaining how doctrinal tension has resulted from the law's evolution. The book also offers a theoretical framework for understanding and analysing the doctrines behind the main tort rules found in different jurisdictions, including their interrelationship and historical development. Steeped in Chilean legal doctrine and case law on torts, it also considers authorities from Britain, Germany, the USA, France and Spain. This is a magisterial and important work.
