Due to the nature of the arbitration process, provisional measures-especially interim protection of rights-tend to play a disproportionate role in international commercial arbitrations. Indeed, the need to clearly define such measures often constitutes the major stumbling block on the path to an effective resolution of a commercial dispute. This concise but enormously useful volume offers practitioners the information and advice they need to overcome this obstacle in the best possible way every time. The Author covers all the relevant avenues of research and practice, from an overview of the concept of provisional measures to an in-depth analysis of the weight and enforceability of such measures. The presentation examines, compares, and analyses seventy sets of arbitration rules on provisional measures (including the arbitration rules of the ICC, AAA, and LCIA), all of the major state laws on commercial arbitration, and detailed analyses of numerous ICC and AAA awards, most of which have not been published before.
