It is hoped that the selection of materials and accompanying text will permit an appreciation of the key issues relevant to the study of this branch of the law. By selecting academic commentary, as well as case law and statutory materials, the authors hope that students will be able to glean an understanding of the wider context in which the law of contract operates. The materials selected are also augmented by a brief analysis of the relevant issues in text form, thereby providing readers with the opportunity to engage in wide reading by reference to footnoted material. The book is based on an issues approach, being subdivided into four parts, namely: (I) Introduction; (II) Contract Formation and Negotiation; (III) Obligations and Risks; and (IV) Performance, Breach and Remedies for Breach of Contract. The first of these parts examines briefly the purposes served by the various rules gathered together under the banner of contract law and pays some attention to policies and ideologies underlying many of the case extracts which follow in later chapters of the book. Part II, on contract formation and negotiation, critically examines the so called classical rules of contract formation and questions whether agreement supported by bargain based consideration is really the basis for contract formation. This part also includes a chapter on the notion of good faith in contract negotiation and the modern expectation that a contracting party will not seek to gain an unfair advantage over others. Part III deals with the issues of obligations and risks arising from the contract and the role of the court as an allocator of risks arising from the contracting process. This part also considers the rules on contractual fairness and generally examines the legal concepts which allow a court to police the contract in the interests of justice. The final part is the longest and concentrates on what is, in practical terms, the most important aspect of contract law, namely, the rules applicable to performance of the contract and the remedies for breach of contract. Throughout the book, the authors have attempted to relate rules of the law of contract to other aspects of the law of civil obligations. As a result, there is reference to relevant rules of tort law and the law of restitution, which should enable students to place this subject in its wider context. The part on remedies in particular makes a number of comparisons between ‘contractual’ rules and ‘tortious’ rules, especially in relation to the issues of remoteness of loss, quantification of damages and factual causation. Readers should note the changes to terminology since the coming into force of the Civil Procedure Rules 1999. We have used the new term ‘claimant’ when discussing general principles of law and the decided cases post-CPR, but have kept the old style ‘plaintiff’ in extracts from and discussion of pre- CPR cases. vii Sourcebook on Contract Law In this edition, there have been changes in the responsibilities of the authors. While the first edition of this book was written substantially by the first named author, Martin Davis has taken a much bigger responsibility for updating work in this edition. For taking this additional responsibility, David Oughton is very appreciative. The authors would like to express their thanks and appreciation to all the staff at Cavendish Publishing, especially Cara Annett for her unfailing patience in waiting for the arrival of the manuscript. Furthermore, we both very much appreciate the considerable help afforded by Veronica Matthew at De Montfort University, particularly for her unstinting help in reviewing the first edition and helping at proof stage. Authors invariably need support from those closest to them. David Oughton would like to thank Sue, Gareth and Karen for putting up with a sometimes grumpy husband and father as he sat staring at a computer screen awaiting inspiration. Their support is much appreciated. Martin Davis would similarly like to thank Jennie. As far as possible, we have attempted to state the law as it stood at the end of September 2000.
