Letters of Credit and Demand Guarantees: Defences to Payment

Book excerpt: This book is the first to provide an extensive analysis of the range of defences to payment under letters of credit and demand guarantees. It considers the extent to which different defences undermine the abstraction of these instruments. This is a fundamental issue, since letters of credit and demand guarantees are designed to be abstract, or autonomous, from the underlying contract that called for their use. The purpose of that abstraction is to provide certainty of payment, but the various defences diminish that certainty. The book examines the spectrum of defences that are frequently litigated and debated in international practice: fraud in the documents, nullity, fraud affecting deferred payment letters of credit, fraud as no honest belief, unconscionable conduct and illegality. Vitally, the book provides analysis of the relevant judicial decisions and offers clear practical guidance on which defences are most suitable for each instrument. As the instruments are heavily used in international trade, this work is particularly suited to financial and commercial law practitioners who draft agreements, as well as those who advise on disputes concerning these instruments. Accessible and engaging, the book is also relevant for academics and students.
