A celebration of the multi-faceted legacy of a key figure in the evolution of international arbitration, this collection of world-class contributions provides critical perspectives and in-depth analyses by leading arbitration professionals and scholars on a wide range of cutting-edge topics in the field of law of which Julian Lew was a founder, and in which he remains an outstanding arbitrator and teacher. Inspired by Lew’s profound influence on the understanding of arbitration as an autonomous and international field of practice, more than forty distinguished contributors address the main trends shaping the arbitration system as it continues to evolve. The chapters in this book offer insightful commentary on a variety of topics gathered under the following headings: applicable law; evidence and procedure; jurisdiction and substantive issues; the arbitrators’ role; the seat; and third-party funders. In a field which has become increasingly busy in terms of events and publications, the high number of contributors to this volume is a testament to the great esteem that Julian Lew enjoys among his peers. With perspectives from a wide diversity of backgrounds, the authors shed clear light on international arbitration’s emerging and future challenges, greatly benefitting the work of both practitioners and academics in the field.
