The WTO has announced that the Arbitrator in the DS583 arbitration appeal under DSU Article 25 was composed on April 28. 2022 "through a random selection from a list of candidates prepared and agreed upon by the parties." Here are the arbitrators in the case (with an indication of the basis for their inclusion in the selection process):
- Mr Seung Wha Chang (former Appellate Body Member)
- Mr Mateo Diego-Fernandez Andrade (MPIA list)
- Mr Guohua Yang (MPIA list)
Not that I think this will tell us much about how the arbitration appeal will be handled, but here's a little WTO adjudication history for each one.
