Study of Appeal facility in international investment arbitration

One of the main reasons for choosing the mechanism of arbitration by the parties to the international investment disputes is the "principle of finality" in the arbitration awards; that is, generally they can not be appealed in merits. But at the same time, the principle of finality has led to different arbitration investment tribunals issued contradictory and sometimes mistaken decisions (final and binding), which, of course, can not correct them in merits. Issuing of such decisions by the tribunals has caused a crisis of incoherence and inconsistence in the international arbitration awards. In order to resolve this crisis, commentators and scholars have proposed various reforms to the international arbitration system that one of the most prominent of which is the creation of a appeal mechanism. This research seeks to analyse the basis of the call for, as well as the potential advantages and disadvantages of an appellate mechanism and its possible effects on the principle of "finality." Finally, it concludes that existing international or regional mechanisms could be used to resolve investment disputes in order to make future reforms to the international investment arbitration system.
