‘This book makes it patently clear that one of the oldest and most important principles in international economic law remains misunderstood. As the authors rightly point out, the significant inconsistencies in the jurisprudence on non-discrimination and regulatory purpose do not provide stability and consistency in the WTO’s dispute settlement system. Nor does it assist the international investment regime, which has been criticized for its unstable jurisprudence. The novel definition of regulatory purpose proposed in this book is logical, well-reasoned and flexible, as is their critique of the jurisprudence, which is useful, comprehensive, and succinct. They also draw welcome comparisons and contrasts between the converging systems of international trade and investment law. It is relevant to all who work in these fields, including policymakers, and recommended accordingly.’

• Contents: 1. Introduction 2. Non-Discrimination and Regulatory Purpose 3. National Treatment and Most-Favoured Nation Treatment in International Trade and Investment Law 4. The Role of Regulatory Purpose in Determining the Appropriate Comparator 5. Less Favourable Treatment 6. Conclusion Index
