...[ this] collection further exemplifies the widespread and very significant influence of Birks' scholarship throughout the common law world...the volume makes a significant contribution to the taxonomic work carried out by Birks. This is both appropriate and most welcome, particularly in the light of its relative absence from Mapping the Law...the volume achieves its end of providing a distinct yet complementary contribution to that volume.The editors and essayists thus deserve sincere thanks for their contribution to what is now a more fully rounded body of work offered in tribute to the great scholar. Elise Bant Canadian Business Law Journal Volume 48, 2009 An edited collection can be assessed on the strength of the individual contributions and on its coherence as a whole. In both respects, Structure and Justification in Private Law excels. The contributions offer a critical perspective on unjust enrichment and on Birks's ideas...Collectively, they offer useful additions to existing debates and will no doubt initiate new ones...this collection will become essential reading to scholars and students researching in the field of unjust enrichment. Nicholas Hopkins Journal of Business Law Issue 6, 2008 The essays frequently challenge Peter's thinking-an approach he would have welcomed for he never retreated from an opportunity to engage in robust scholarly debate...Inevitably, so short a review cannot do full justice to the strength and diversity of views which this collection brings together. The editors have managed to structure the array of differing views into a coherent whole. It certainly offers the reader an exhaustive and comprehensive insight into the controversies which Birks's own thinking generated and the essays not only engage with the current debates on unjust enrichment, they will no doubt generate new ones. As such the collection will long be a point of reference for scholars. Finally, as is typical of Hart Publishing, ease of reference is facilitated by detailed indexing and the overall quality of the publication is excellent. This impressive work is a welcome and necessary addition to the literature on private law and unjust enrichment. John Lowry King's Law Journal 20:1 ...all of the essays in this book are of high quality and generate valuable theoretical insights. This is an outstanding collection of essays which should be read by everybody who is interested in the law of unjust enrichment. Qi Zhou Legal Studies Vol 29, No. 2
