This is a welcome addition to unjust enrichment scholarship, as the study of defenses (and the change of position defence in particular) has been central to the development of this area of law in recent years.

[The book] offer[s] a timely and rigorous analysis of some of the core problems currently debated by unjust enrichment scholar[s].

[T]he various contributions in this volume provide the reader with state-of-the-art academic analysis of the law of unjust enrichment, together with the most relevant critique of this type of intellectual project. Together, they make for a thought-provoking collection for any reader interested in the fundamental problems of private law theory.

the editors and contributors are to be congratulated on a book which will stimulate further necessary debate about defences to unjust enrichment claims. It should be widely read and engaged with. I look forward to the next instalments in the editors' series, on defences in contract and equity.

this book … contains a host of insights, suggestions and arguments that are sure to spawn the kind of new writing on unjust enrichment that is so essential if this area of law is to flourish on sound foundations.
