This article argues that investor – state dispute settlement system need to gather experience from the WTO system so as to increase its legitimacy. The article looks at the issues haunting the investor – state adjudication system and examines how the same have been addressed at the World Trade Organization. The WTO DSU is taken as a comparator because it is being praised for attaining legitimacy within a short period of time. The article concludes that investor – state adjudicative system has a lot to learn from the WTO adjudicative system with regards to costs, timeframe, remedies and the appellate structure.eninvestorstate adjudication systemlegitimacy crisisdispute settlement systemArticle
