<b>This book explores the relationship between the English law of unjust enrichment and legal obligations arising from other branches of the law.</b><br/><br/>It examines the question primarily by considering how English courts resolve conflicts between restitution claims and countervailing legal entitlements. This is much needed given recent cases such as <i>IEG v Zurich Insurance</i> and <i>Avonwick Holdings Ltd v Azitio Holdings Ltd</i> clearly showing the differing positions taken by English courts on the question. <br/><br/>By applying insights from the theory of unjust enrichment to Anglo-Australian case law this study gives a welcome cogent explanation of a complex question.
