I have been critical of attempts to turn Article 25 arbitration into an appellate mechanism.
I also understand that once you start with the proposition that a "review mechanism" is necessary, then there are few options - and this is one.
What does it all mean? 1/
In the WTO, "symbolic validation" is provided by *adoption* of reports by the DSB; "pedigree" is provided through the nomination and appointment process for AB members. 3/
Some argue that because of Article 3.2, panels would be required to pay heed to arbitration reports. After all, they are reported to and "noted by" the DSB.
In legal terms, this is poppycock. 8/
Canada and the EU have the sovereign right to appoint them as arbitrators; the United States, 9/
This is not limited to the United States, of course, or to unrenominated or unreappointed AB members. 10/
And if they are not required to do so, if a report goes against their interests, they will not do so. 11/
