This book, now in its second edition, presents the core legal rules applicable to business operations from an international perspective. Covering a wide range of topics, it notably addresses contracts, agency, intellectual property (including licensing), security rights (such as letters of credit), and financial instruments. It also outlines general principles related to business crimes, non-contractual liabilities, constitutional liberties, and procedural rules. What sets this edition apart is its approach, which systematically begins with international sources that are increasingly shaping a nearly universal understanding of legal instruments and the legal environment of business. This updated edition is designed for a multinational audience of students in management and economics, but will also be valuable for lawyers seeking an international perspective.
