Powell, John Joseph. Essay Upon the Law of Contracts and Agreements. Walpole: Printed, At the Press of Thomas & Thomas, by David Newhall, 1802. Two volumes. Reprint available January 2005 by the Lawbook Exchange, Ltd. ISBN 1-58477-520-3. Cloth. $150. * Reprint of the first American edition of the first treatise on the subject. (It is based on the first London edition, 1790, to which it is starred.) Powell [1755?-1801] wrote several distinguished treatises that were used widely in England and America, including this one. Though mildly critical of its organization, Holdsworth considers it "an able book" that "is much more than a digest of cases" because "[i]n all cases the author tries, with considerable success, to state principles, and to illustrate them by cases.": History of English Law XII:392.

This text explains and analyzes the law of contract, and provides a detailed examination of many areas of controversy and difficulty. Amongst recent developments examined is the Contracts (Rights of Third Parties) Bill.

In recent years there has been a revival of interest in the philosophical study of contract law. In 1981 Charles Fried claimed that contract law is based on the philosophy of promise and this has generated what is today known as 'the contract and promise debate'. Cutting to the heart of contemporary discussions, this volume brings together leading philosophers, legal theorists, and contract lawyers to debate the philosophical foundations of this area of law. Divided into two parts, the first explores general themes in the contract theory literature, including the philosophy of promising, the nature of contractual obligation, economic accounts of contract law, and the relationship between contract law and moral values such as personal autonomy and distributive justice. The second part uses these philosophical ideas to make progress in doctrinal debates, relating for example to contract interpretation, unfair terms, good faith, vitiating factors, and remedies. Together, the essays provide a picture of the current state of research in this revitalized area of law, and pave the way for future study and debate.

Although presented as being derived from the past, principles in contract law have been subject to constant reformulation, thereby facilitating legal change while simultaneously seeming to preclude it. Principle and policy have been mutually interdependent, propositions not usually being called principles unless they have been perceived to lead to just results in particular cases, and as likely to produce results in future cases that accord with common sense, commercial convenience and sound public policy. The influence of policy has been frequent in contract law, but Stephen Waddams argues that an unmediated appeal to non-legal sources of policy has been constrained by the need to formulate generalised propositions recognised as legal principles. This interrelation of principle and policy has played an important role in enabling an uncodified system to hold a middle course between a rigid formalism on the one hand and an unconstrained instrumentalism on the other.

Understanding Contract Law provides an accessible, in-depth analysis of the purpose of contracting and the role of the law of contract, as well as theories that inform it. Assessing the historical development of this cornerstone of law, the book provides detailed analysis of some of the leading theoretical explanations, and how they are applied in jurisdictions throughout the world. With a new chapter examining the impact of globalization on contract law, this new edition also includes recent behavioural research around responses to contract breach. The book’s accessibility is enhanced by text boxes defining key concepts and terms, and biographical notes of leading figures and scholars. This ensures that readers are able to gain a clear understanding of the narratives and theories explained in the book, and to appreciate how contract law has evolved. Uniquely, the book is not limited to one jurisdiction, making this an essential text for students wishing to expand their knowledge of this fundamental area of law around the world.
