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.

Course-focused and comprehensive, the Textbook on series provides an accessible overview of the key areas on the law curriculum. This chapter focuses on the legal treatment of mistakes that are presumed to nullify consent if both parties entered into the contract under the same fundamental mistake, assuming the absence of a provision of the contract allocating the risk of this initial impossibility. 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. Under these circumstances, the contract is automatically void and any money or property involved has to be returned. Fine distinctions can arise in terms of the legal treatment of impossibility 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 very rarely be sufficiently fundamental to render the contract void since impossibility of the contractual adventure is required. 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 which were rejected in Great Peace Shipping Ltd v Tsavliris (International) Ltd and the fact that this means there is no remedial flexibility in such instances.

Indonesia is one of the most legally diverse and complex countries in the world. It practises legal pluralism with three types of contract law in force: adat (customary) contract laws, Islamic contract laws (mostly concerning banking), and the European civil law of contract, transplanted from the Netherlands in 1847, found mainly in the Civil Code (Kitab Undang-Undang Hukum Perdata). This chapter focuses on European civil law as it is the law used for the majority of commercial transactions. The civil law of contract is not well developed and there is a paucity of indigenous doctrine and jurisprudence, since most significant commercial disputes are settled by arbitration. The contours of the law are consistent with the French/Dutch legal tradition. In the formation of contracts, the subjective intention of the parties plays a greater role than in the common law. As with most jurisdictions with a Napoleonic tradition, the offer must include all the essential element of the contract, there is no concept of ‘invitations to treat’ or of ‘consideration’, the common law posting rule is rejected, and the contract is formed only when the acceptance is received. There are generally few requirements of form but some contracts must be in writing and some in a notarial deed.

This chapter analyses the law on third party beneficiaries in Hong Kong long characterized by strict adherence to the traditional common law doctrine of privity. The law relating to third party rights was only reformed by way of Ordinance in 2016, along the lines of the statutory reform of English law in 1999. A small number of specifically enumerated types of contract are excluded from the scope of the Ordinance; other contracts may be concluded to confer enforceable contractual rights on third parties. Whether a third party may enforce a term of a contract depends on the interpretation of the contract: if the third party right was not expressly conferred there is a presumption that the conferral was intended; but this can be rebutted if the parties made it clear that they did not intend it to be enforceable. The third party must be identified by name, as a member of a class, or answering a particular description and may claim the same remedies for breach as a party to the contract.

Although the law relating to common mistake has engendered a plethora of conundrums, many problem areas have in fact been well-traversed in the literature. The present article does not seek to re-cover such welltrodden ground, but attempts, instead, to suggest a different and more systematic approach that would effect a merger of the common law and equitable branches of common mistake into one coherent, doctrine.

Singapore’s contract law framework, in the context of third party beneficiaries, has stayed faithful to the approach taken under English law. The common law in Singapore has adopted the privity of contract rule, various common law exceptions to the rule, and a statutory regime to empower third parties to enforce contractual terms in prescribed circumstances. The privity rule confines the benefits and burdens under a contract to the contract parties; only they have given consideration and only they can sue and be sued under it. However, various reasons support the third party beneficiary having some right to enforce that benefit and a range of common law mechanisms have been recognized by the courts to allow the third party to do this. Some are true exceptions, others operate by recharacterizing the status of the third party into that of a primary party, thereby eliminating the lack of privity. In cases where the third party may potentially be able to sue the promisor in tort, the basis for loosening the privity doctrine to permit the third party to sue the promisor in contract, and the character of the damages recoverable from the party in breach, requires closer scrutiny.

This note analyses the UK Supreme Court’s decision in Rock Advertising Ltd v MWB Business Exchange Centres Ltd, a case that confirms the long uncertain ability of ‘No Oral Modification’ clauses to exclude informal variations in English law. This note argues that, while the Court was correct to reject the putative oral variation in question, the majority’s description of the law is unsatisfactory because of its detachment from wider contract law principle, and compares unfavourably with the alternative ratio by which Lord Briggs reached a concurring outcome. This note also comments on the Supreme Court’s (cursory) treatment of the portentous Court of Appeal decision in Williams v Roffey Bros, which has reformulated the law on contract variation across common law jurisdictions. The Court acknowledged, but declined to resolve, the tensions Roffey introduced in to the law on part payment of debts. While it is unfortunate that the opportunity to resolve these tensions was missed, this note endorses the Court’s ( obiter) rejection of the analysis by which the Court of Appeal below sought to extend Roffey to the part payment of debts.

This chapter examines the law of contract in France and discusses the milestone reform of French contract law. While this new legislation introduces a fresh equilibrium between the contracting parties and enhances accessibility and legal certainty in contract, it does not radically change the state of the law in this area. In addition, it does not strongly impact the traditional philosophical foundations of the law of contract. The reform, in short, looks more like a tidying up operation rather than a far-reaching transformation of the law. Therefore, the chapter argues that it is questionable whether the new law, which was also intended to increase France's attractiveness against the background of a world market dominated by the Common Law, will keep its promise.

This chapter discusses the law on third party beneficiaries in Japan; mostly characterized by adherence to the German model that still bears an imprint on Japanese contract law. Thus, there is neither a doctrine of consideration nor any other justification for a general doctrine of privity, and contracts for the benefit of third parties are generally enforceable as a matter of course. Whether an enforceable right on the part of a third party is created is simply a matter of interpretation of the contract which is always made on a case-by-case analysis but there are a number of typical scenarios where the courts normally find the existence (or non-existence) of a contract for the benefit of a third party. In the recent debate on reform of Japanese contract law, wide-ranging suggestions were made for revision of the provisions on contracts for the benefit of third parties in the Japanese Civil Code. However, it turned out that reform in this area was confined to a very limited codification of established case law.

This chapter describes current sources and techniques useful for finding seventeenth- and eighteenth-century laws of England and introduces some methods an attorney in England in the seventeenth and eighteenth centuries might have used. Before researchers can find the law, they must know what was considered to be the source of law in the period being investigated. Reporting, publishing, and finding cases has been important in English law for centuries. Parliamentary enactments during the colonial period also play an important part in the framework surrounding any particular legal issue. Meanwhile, English law is built on a foundation of common law, which is built on case law. As such, finding cases that relate to a particular topic is critical in research. A good case-finding option is a digest of cases; these have been written over the centuries, as have abridgments and treatises on particular areas of law.
