The topic of harmonization of European private law, and European contract law in particular, is rapidly gaining in importance. The topic is not only widely studied by academics and students all over Europe (and even beyond), it is also on the political agenda of the European Parliament, the European Commission and the European Council. The most important achievement in this field is the Principles of European Contract Law (PECL), drafted by the Commission on European Contract Law. The European Commission considers the PECL to be a serious option for further harmonization of European contract law within the European Union. This publication provides a systematic overview of the PECL in comparison with Dutch contract law as a whole. The book is concise and because of its structure it is easily accessible. Amongst the contributors there are many highly distinguished contract law specialists. It may be used at universities in courses on Comparative Law, European Private Law, and European Contract Law.
