Despite the clear ability of MFN clauses to have an enormous impact on the freedom of state and the rights of the investors, very little work and cases has been performed on the manner in which the MFN clauses operates in the investment arbitration tribunal's jurisdiction. The goal of this book is to fill in this gap. By providing a baseline analysis of the operation of MFN clauses and examine the jurisprudence in the international investment context, this work will explain the appropriate means of determining when a given dispute resolution procedure is indeed more favorable than the procedure included in the BIT containing the MFN clause.
