Provisional measures are an increasingly important mechanism for investment protection in investment arbitration. There is a critical mass of jurisprudence as well as numerous cases that have exhibited novel uses for provisional measures, calling for a thorough examination. Rubins and Love's work is the first to provide in-depth coverage of this increasingly important subject and their work provides an invaluable academic and practical resource. The book is organized by topic and covers the full range of jurisprudence to date, using comparative legal analysis to shed light on each issue. It provides an overview of provisional measures and their function in investment arbitration, including the basic legal documents and provisions relevant to the topic. The authors set out the elements considered in granting provisional measures, discuss the two key issues of the relationship of provisional measures with parallel proceedings, analyse the enforcement of provisional measures, and assess the future direction and growth of provisional measures in investment arbitration.
