This book is devoted to the applicable law to contractual and non-contractual obligations in the European Union. The Rome I and II Regulations provide uniform conflict of laws rule in order to avoid undue forum-shopping. In theory all national courts of EU Member States (excluding Denmark) apply the same rules determining the applicable law. Rome I and II in Practice examines whether the theory has been put into practice and assesses difficulties that may have arisen in the interpretation and application of these Regulations. Such study appears invaluable as the Rome I and II Regulations may be seen as a critical stepping stone towards the construction of a true and far-reaching European Private International Law.
