'… the monograph does not go out of bounds and does acknowledge limitations, as in ignoring them one would run the risk of denaturing arbitration itself as a mode of settlement of investment disputes. The monograph is a meticulous attempt at establishing the legitimacy on international investment law and ITA as a branch of public international law. For academicians, students and even practitioners of international investment law, this monograph is a must read.' Pushkar Anand, Indian Journal of International Law
