Book excerpt: This book offers an updated article-by-article commentary of the Rome I Regulation, applicable in the courts of nearly all European countries to identify the law applicable to international contracts. The commentary is authored by an international group of academics and practitioners, who all have practical experience with international contracts and, thus, were able to focus on the needs of practice. This volume will be not only a reference guide for judges and practitioners alike, but also a crucial resource for academics and researchers.
