As always, very impressive, a real public service. If I could be contrarian for a bit, Chevron v Ecuador is, in boring formalist PIL terms, almost entirely unexciting, if with some smaller points of interest: (1) Estoppel as a basis of jurisdiction.

As per the Tribunal, Ecuador cannot simultaneously (via its courts) say that Chevron has an investment, and then object in investment arbitration that it does not. Seems prima facie plausible but raises a number of technical points.
