This book provides a clear and concise account of the general principles of the law of contract. It is an excellent introduction to the subject, giving the reader an overall view which, for some will be all that is required and for others is an essential basis for the more detailed study of particular aspects of the law. It is also a valuable tool for revision, enabling the student quickly to recall and put in context the essentials of the subject. The book does not over-simplify the law, but explores areas of doubt and difficulty and offers reasoned criticism of controversial decisions. The major change in this edition is the incorporation of the Contracts (Rights of Third Parties) Act 1999 which makes important changes to a central aspect of the law of contract. The relation of the Act to the existing rules of common law and equity is fully explored. Account is also taken of recent case law on offer and acceptance, implied terms, damages and undue influence. The book is cross-referenced to the author's eleventh edition of Smith & Thomas, a Casebook on Contract which provides extracts from nearly all the leading cases together with notes and questions. Taken together, the two books provide the necessary materials for an advanced study of the subject.
