This book looks at how European private international law is applied by English courts. Focusing on unjust enrichment claims, it asks the question (from the perspective of the litigant) whether the English courts have jurisdiction to hear and decide such disputes and, if so, whether they should exercise that jurisdiction? In answering the question, it examines the Brussels I, Rome I and Rome II regulations. Balancing theoretical explorations and practical problems, this important book will appeal to scholars and practitioners alike.
