This book unlocks the content, approaches and objectives of European contract law. European contract law is not only a core aspect of European private law but also plays a highly important role in the development of contract law at a national level. However, European contract law's contribution and significance are often overlooked and its content, approaches and objectives are not fully understood.This revised and updated 3rd edition provides fundamental information about core EU legislation, court decisions, and academic projects in order to show how a system arises from the interaction between the different sources. Moreover, this 3rd edition takes into account the recent legislative responses to digitalisation and the development of a contract law for the 21st century, in particular the new Digital Content and Sale of Goods Directives.
