Chapter Summary

The book runs to about 650 pages. Its published contents divide it into seven blocks: an introduction, contract formation, privity, vitiating factors, the contents of contracts, breach and remedies for breach, and good faith. The publisher says that each area of the law begins with an overview of the interests, values and concerns involved and then covers the doctrine together with its complexities and controversies. Only the block titles and page spans are listed publicly, so the summaries below stay at that level and add the chapter-specific points that the publisher's new-edition notes supply.

Introduction (pp. 1–38)

A short opening block that precedes the doctrine. The publicly listed contents do not itemise it.

Contract Formation (pp. 39–154)

The second-longest block, on how a contract comes into being. Two new-edition discussions belong here: the effect of digital disruption on formation (Chapter 2) and the Law Commission's advice to government on smart legal contracts (2021) (Chapter 3).

Privity (pp. 155–188)

A compact block on who can sue on a contract and who is affected by one. According to the publisher, Chapter 4 has substantial new case law, including the three joined Supreme Court decisions in Secretary of State for DEFRA v PCSU (2024) on the presumption favouring third-party enforcement under section 1(1)(b) of the 1999 Act, Armstead v RSA (2024) on contractual liability imposed on a tortfeasor, and a new discussion of whether third parties may benefit from terms implied by the Sale of Goods Act and the Consumer Rights Act 2015.

Vitiating Factors (pp. 189–370)

The largest block, at about 180 pages, covering the grounds on which an apparently valid agreement may be challenged. The publisher singles out new material on automated contracting, mistake and rectification in Chapter 6.

The Contents of Contracts (pp. 371–460)

About ninety pages on the terms of a contract, as the block title indicates. The publisher lists interpretation, implied terms and contractual powers among the topics whose analysis was updated.

Breach and Remedies for Breach (pp. 461–574)

Breach and its consequences. The publisher reports structural and doctrinal changes across Chapters 11 to 15: a restructured Chapter 11, a new summary of illegality, a new section on the justification for termination, and updated discussion of mitigation, restitution, inadequacy of damages, injunctions and good faith.

Good Faith (pp. 575–600)

The closing block, a little over twenty pages, is given to good faith.

Other Updates Named by the Publisher

Chapter 7 develops the frustration doctrine further, with a reference to the Chinese Civil Code 2020. The treatment of the Digital Markets, Competition and Consumer Act 2024 is expanded, including that Act's approach to "subscription traps". The analysis of undue influence, guarantees, interpretation, implied terms and contractual powers is updated, with decisions including Waller Edwards v One Savings Bank (2025), Parker Grennan v Camelot (2024) and Tesco v USDAW (2024).

Key Concepts

Formation and Third Parties

• Digital disruption and smart legal contracts: how automated and technology-mediated dealing affects the rules on forming a contract, discussed in Chapters 2 and 3.
• Third-party enforcement: the presumption under section 1(1)(b) of the 1999 Act in favour of a third party's right to enforce a term.

Challenging and Ending Agreements

• Mistake and rectification: errors in making or recording a contract, with new material on automated contracting.
• Undue influence and guarantees: protection for a party whose consent was improperly obtained, with updated cases on guarantees.
• Frustration: the doctrine under which a supervening event can end a contract, developed further in Chapter 7.
• Illegality: given a new summary in Chapters 11 to 15.

Terms and Remedies

• Interpretation, implied terms and contractual powers: how the content of a contract is established and controlled.
• Termination, mitigation, restitution and injunctions: the remedial topics the publisher says were revised.
• Good faith: the subject of the final block.

Critical Analysis

Strengths

• A visual presentation. The publisher stresses extensive use of diagrams, and the e-book adds animated diagrams, so the book is designed to show how the doctrines connect.
• Values alongside doctrine. Each area opens with the interests, values and concerns it involves, and "counterpoint" and "reflection" boxes ask the reader to engage with law reform. This suits essay questions as well as problem questions.
• Recent authority. The new-edition notes cite decisions from 2023 to 2025 and a statute from 2024, so the book is a good guide to what examiners may expect to be current.
• A comparative outlook. The author is an editor of Chitty on Contracts and of a series on the contract laws of Asia, and the new edition refers to the Chinese Civil Code on frustration, which gives the English rules a point of comparison.

Limitations

• Length. At about 650 pages, with an announced aim of full coverage of contract law's complexities and controversies, the book offers more than a student needs for a first pass through a syllabus, and readers must choose what to skip.
• Study aids in the e-book. The animated diagrams, the guidance on answering the end-of-chapter questions and the "chapters in essence" summaries are described as e-book features, so readers of the print edition have fewer supports.
• Only a coarse contents list is public. The chapter-by-chapter structure inside the seven blocks is not itemised in the sources available for this guide, so readers should check the full contents page before relying on it for a particular syllabus.

Where It Fits in the Course

Among the contract books in this course list, this is the textbook that leans most openly toward explanation and justification. Poole's Textbook on Contract Law is presented as a case-driven account that sets contract within its commercial context and is organised in four parts, so the two make a natural pair: one for the rules and their commercial setting, the other for the reasons behind them. Taylor and Taylor's Contract Law, in Oxford's Directions series, describes itself as plain prose with highlighted case extracts and self-test features, and is a gentler starting point for students who find a long text daunting.

Anson's Law of Contract is a long-established treatise and is best used to chase the authorities behind a point, not read through. Burrows's A Casebook on Contract supplies the primary materials, beginning with offer and acceptance, and works well alongside this book when a discussion needs the original judgment. Stephen Smith's article on duress is a theoretical study that can accompany the vitiating factors block.

How to Use This Book

The publisher presents the book as a course text that builds both conceptual knowledge and analytical skills in English contract law. It is for students who are ready to read about why rules exist as well as what they are, and who will read cases alongside the text.

A practical plan:

• Core: the blocks on formation, vitiating factors, the contents of contracts, and breach and remedies, in the order the course teaches them. The privity block is short and should be read with the 1999 Act in hand.
• Optional on a first reading: the discussions of smart legal contracts and automated contracting, the comparative reference to the Chinese Civil Code, and the closing block on good faith can wait for essay work.
• Practice: use the end-of-chapter questions, and in the e-book the guidance on answering them, to test understanding. Treat the reflection and counterpoint boxes as essay prompts, and use the cases named in the new-edition notes as a list of recent authorities for problem questions.
