This informative and accessible book reviews the core concepts of contract law and theory from an Anglo-American perspective. Larry A. Di Matteo deftly analyses the key principles, rules and frameworks which have shaped Anglo-American contract law, as well as highlighting important legislative acts that have changed and modernised its development.There is a strong commonality across Anglo-American common law systems; however, there have been several critical fissures that have developed between American and English common law over the past fifty years. Di Matteo adopts a multidisciplinary approach, lucidly explaining these differences from both a theoretical and a practical perspective, using empirical evidence from case studies to support this research. The areas of divergence discussed include the duty of good faith, principle of unconscionability, promissory estoppel, contextual interpretation, and hardship. Introducing key contract law cases, this book will be an essential read for law students and scholars working in the field of commercial law, particularly those with an interest in the theoretical framework and historical context of modern contract law.
