The Influence of the 2014 UNCITRAL Transparency Rules on Treaty-based Investor-State-Arbitration

Investor-state dispute settlement proceedings have taken place behind closed doors for a long time. Due to the involvement of nation states and the fact that such proceedings may affect highly political contro-versies, a minimum of transparency is required for legitimacy reasons. The UNCITRAL Rules on Transparency in Treaty-based Investor-State Arbitration are an attempt towards more transparency in such proceedings. The present dissertation examines whether and to what extent arbitration practise and nation states, when negotiating international investment agreements, have committed towards more transparency since the introduction of the UNCITRAL Transparency Rules.
