You are right, it does not say anything about the Permanent Court of Arbitration's decision on the matter. I was more trying to make the point, that various court decisions related to this matter (the original decision against chevron as well as the case against Donziger) seem to be cast into doubt by external "impartial looking" entities, turning the water very, very muddy here.

But then I must admit, that I do not have a very high opinion of "arbitration courts" in general, as often they seem to have various conflicts of interests with regards to how they earn money by being paid by parties bringing the cases (i.e. deciding against the interests of a party which usually provides high-income cases, would risk the court's own financing).
