In the current investment climate, most investment disputes are settled through arbitration. This indispensable book is the original legal recourse, bringing together the well-known investor-state disputes and commentary on the increasingly significant subject of parallel proceedings. It fills the need for a detail knowledge of the issue of parallel proceedings into well-organised chapters covering the all essential aspects of the subject. The book not only analysis the origin of the issue but also provides several domestic remedies to reduce the risk of parallel proceedings. Therefore, it will be of inestimable value to academics in the field as well as to practitioners.
