Inconsistency in legal interpretation is among the most salient problems in investor-State dispute settlement (ISDS) and it is one of the key issues being addressed by the reform efforts in the United Nations Commission on International Trade Law (UNCITRAL) Working Group III.

This article seeks to parse the problem of inconsistency at a more granular level, in order to distinguish between types of norms where a degree of inconsistency is (relatively) manageable and (potentially) tolerable, and those where inconsistency is unacceptable. We argue that it is with regard to structural ‘rules of the game’ where inconsistency is most destructive.
