This chapter analyses the legal issues concerning the jurisdiction of an arbitral tribunal. It considers a range of problems, including questions of jurisdiction and admissibility, the validity and effectiveness of an arbitration agreement, and arbitrability.

There are a number of heavily contested questions, but it is argued that these are unlikely to be resolved easily, because they are a reflection in miniature of the major continuing uncertainties surrounding the identity and character of international arbitration itself
