Investment treaty arbitration is most commonly looked at as a hybrid between public international law and international commercial arbitration. It is usually considered to be an offshoot of international commercial arbitration. Therefore, it resembles more of private law than public international law. Eric De Brabandrere, however, in his book Investment Treaty Arbitration as International Law: Procedural Aspects and Implications, has argued against this common perception. He has taken upon a daunting task of showing how investment treaty arbitration is essentially public international law.
