Since the decision of the International Court of Justice in LaGrand (Germany v United States of America), the law of provisional measures has expanded dramatically both in terms of the volume of relevant decisions and the complexity of their reasoning. Provisional Measures before International Courts and Tribunals seeks to describe and evaluate this expansion, and to undertake a comparative analysis of provisional measures jurisprudence in a range of significant international courts and tribunals so as to situate interim relief in the wider procedure of those adjudicative bodies. The result is the first comprehensive examination of the law of provisional measures in over a decade, and the first to compare investor-state arbitration jurisprudence with more traditional inter-state courts and tribunals.
