Part VI The Post-Award Phase, 30 A Practical Guide: Research Tools in International Investment Law

This chapter aims to help the new investment arbitration practitioner identify and find the main legal sources for dealing with international investment law issues. Three different topics need to be addressed in order to cover, as extensively as possible, the legal issues generally raised during an arbitration based on an international investment agreement. First, even though the stare decisis rule does not exist in international arbitration, including investment arbitration, previous rulings are often used and analyzed by arbitrators. Second, when dealing with investment arbitration, it is likely that the claim will be treaty based. Finally, and most importantly, in international investment disputes, arbitral tribunals rely on all the sources of public international law identified in Article 38(1) of the Statute of the International Court of Justice, which provides for the Court to apply.
