Emergency Arbitration is the first work of its kind to provide clear and authoritative guidance on the practice and theory of this increasingly utilized procedure. By examining the leading emergency arbitration rules, the book identifies a common procedural framework for the commencement, conduct, and decision-making process in an emergency arbitration. This framework is developed through the articulation of 'The Fifteen Principles of Emergency Arbitration'. These are aimed at giving parties greater control and certainty in bringing and defending applications for emergency measures. The book combines a practical approach, including the use of flowcharts and tables, with in-depth analysis of important issues arising in emergency arbitration. These include the status of the emergency arbitrator; the relationship between the emergency arbitrator, the arbitral tribunal, and courts; the role of the seat of emergency arbitration; applicable laws and transnational standards; due process requirements; the enforceability of decisions; and use of the procedure in investment treaty arbitration. Emergency Arbitration is thus a vital companion to those contemplating, or facing, an emergency arbitration.
