This book is a unique and extensive comparative study of commercial contract interpretation across 14 selected jurisdictions, namely Croatia, England and Wales, Finland, France, Germany, Greece, Italy, The Netherlands, Poland, Portugal, Scotland, South Africa, Spain and Sweden. Using a dynamic comparative case method, the focus is centered on the discussion of key legal problems, further examined in a detailed and comprehensive comparative analysis. In this way, the book makes important advancements in the general understanding of contract interpretation in European private law in three respects. First, it enriches the conventional conceptual framework for the methods of contract interpretation by distinguishing between interpretation aims and means. Second, it challenges the presumptive division of common law and civil law jurisdictions, for example, the assumption that civil systems follow a subjective approach and common law systems an objective approach to interpretation of contract. Third, the book provides a more subtle analysis of the role of standards of good faith in contract interpretation.
