This casebook is designed for the professor who takes seriously the often-articulated goals of teaching case analysis and the impact of social and economic factors on the common law. Enough of the majority opinions, and often the dissenting opinions, is presented to illustrate how the cases fit together with precedents and to enable students to evaluate competing arguments. The latest edition, though streamlined from previous editions, adds both coverage of emerging areas of liability, including claims under the alien tort statute, and traditional torts applied in new factual contexts, such as cyberspace and biomedical engineering.
