The future of international investment treaties through a "way" of authentic interpretation. What limits and remedies are there?

Abstract: Authentic interpretation is not a type of interpretation that has been provided for in the treaty system of the Vienna Convention on the Law of Treaties. It would be even more difficult to find a way out of authentic interpretation in investment treaties. The new types of treaties have opened the way, especially in the NAFTA, WTO system, to a mechanism of arbitrations, which on the one hand resolves the disputes and on the other hand functions as a new possibility of authentication, that evolves through the procedural process of interpretation, which tries to overcome the relative limits, which are created during the litigation process.
