Disputes involving trade and investment in services are a rarity in the WTO. Up to now, the WTO dispute settlement mechanism (DSM) has addressed over 130 cases, of which a handful concerned trade and investment in services. It is possible to identify three relevant reasons that may explain, at least to some extent, the marginal attention that WTO dispute settlement has needed to pay to investment in services. This study attempts to explore two aspects of international disputes in investment in services. In a first part, it focuses on the international agreements granting standing for private parties in international dispute settlement procedure. With regard to WTO dispute settlement mechanism, the study attempts to explore how the disciplines of the Understanding on Dispute Settlement Procedures (DSU) together with the disciplines adopted in the GATS relate to foreign investors in services.
