Investment treaty arbitrations may be brought under the rules of many different arbitration institutions. As can be expected, each institution has its unique rules and associated collection of risks and benefits. The table below provides a quick reference guide for the rules of several key institutions, the SIAC, the SCC, ICSID, UNCITRAL, and the PCA.

This is a simplified guide intended to provide an overview of the similarities and differences among some of the major institutional and ad hoc international arbitration rules. It is not intended as a substitute for detailed legal advice as to the procedures and laws which govern a particular dispute. Advice should be sought when agreeing to arbitration and at any early stage of any dispute.
