Course-focused and comprehensive, Poole’s Textbook on Contract Law provides an accessible overview of the key areas on the law curriculum. Under English law, bargains and not gratuitous promises are enforced, thus a promise will not be enforceable if it is not contained in a deed (implying that any promise is taken seriously) or supported by consideration. Consideration refers to an act or a promise given in exchange for the promise (that is, the price for which the other’s promise was bought). The law does not recognize some acts or promises as good consideration, such as past consideration and performance of an existing legal duty. This chapter examines the general requirement in English law to provide consideration in order to enforce a contractual promise. The consideration requirement is relevant not only to the formation of a contract but also to the enforceability of promises altering the terms of an existing contract (alterations). An alteration promise that is not supported by consideration may still have some binding effect on the basis of the doctrine of promissory estoppel.

This introductory chapter first considers the nature and function of contract. It then discusses the contractual obligations in English law; the content of the contract law as set out in this book, which is concerned with the ‘general principles’ of contract rather than the detailed rules applicable to different types of contracts; the location of contract as part of the law of obligations and its relation to other parts of the law of obligations, tort and restitution of an unjust enrichment, and property law.

English law does not currently recognise a general duty of good faith, but this position is increasingly being challenged. In addition, good faith informs a diverse range of legal doctrines and principles. This chapter addresses the following: the meaning of good faith; good faith in current contract law; and the nature of good faith. It further considers whether English law should recognise a general good faith doctrine and the difference this might make to various aspects of the law.

Chapter 9 concerns contexts in which two parties, A and B, have either entered into a contract or taken significant steps to form a contractual relationship, and B is at risk of incurring an unbargained-for loss that A could prevent by taking an action that would not require her to forgo a bargaining advantage, undertake a significant risk, or incur some other material cost. In the contexts described in this chapter A is under a moral and legal duty to take action—a duty referred to in this book as the duty to rescue in contract law. Among the contexts in which the duty is imposed are silence as acceptance, late acceptance, and performance.

Course-focused and comprehensive, Poole’s Textbook on Contract Law provides an accessible overview of the key areas on the law curriculum. This chapter focuses on the legal treatment of ‘mistake’. It considers mistakes that prevent agreement (mutual or cross-purposes mistakes and unilateral mistake as to terms, particularly identity mistakes). It also examines the remedy of rectification when the contract does not accurately reflect what the parties agreed. It also considers the defence of non est factum. It then considers mistakes that are presumed to nullify consent if both parties entered into the contract under the same fundamental mistake. The doctrine of common mistake in English law is designed to protect the interests of third parties and to ensure certainty in transactions. A fundamental common mistake arises in cases where there is true impossibility or failure of consideration; the contract is automatically void and any money or property involved has to be returned. Distinctions can arise depending upon whether the impossibility is initial (common mistake) or subsequent (frustration doctrine). Categories of common mistake at common law include mistake as to subject matter (res extincta) and mistake as to ownership (res sua). A mistake as to quality will rarely be sufficiently fundamental to render the contract void. This chapter also discusses Lord Denning’s attempts to introduce an equitable jurisdiction to set aside on terms in cases of mistakes as to quality. These were rejected in Great Peace Shipping Ltd v Tsavliris (International) Ltd meaning that there is no remedial flexibility in such instances.

This introduction provides an overview of contracts and the law of contract. It first explains what the law of contract is about and why it matters before discussing the tasks of contract law. It then considers the role of debates in contract law, unity and diversity in contract law, and central issues in contract law. It also examines the main perspectives about contract that have influenced English law, including perspectives that used to be historically important. In particular, it explores the notions of bargains and the will. The chapter goes on to address two very different understandings of contracts: one that sees it primarily as a bundle of rights, and one that sees it as a relationship between the parties.

Abstract Some nineteenth century writers like the Scottish born poet William Golder, used the term ‘the Great Britain of the south’ as a description of his new home. He was not alone in this characterisation. There were of course other possible perspectives, not least from the Māori point of view, which these British writers inevitably fail to capture. A third reality was more specific to lawyers or at least to those caught up in the legal system. The phrase ‘the Great Britain of the south’ fails to capture the complexity of the way that English law was applied in the early colony. The law administered throughout the British Empire reflected the common law origins of colonial legal systems but did not mean that the law was identical to that in England. Scholars have emphasised the adaptability of English law in various colonial settings. New Zealand contract law of this time did draw on some English precedents. The early lawyers were steeped in the English legal tradition. At the same time, English authorities were used with a light touch. The legal and social framework within which contract law operated was also quite different. This meant, for example, that mercantile juries were important in adapting the law to local conditions. Early New Zealand contract law provides a good example of both the importance of English law in a colonial setting and its adaptability.
