For the five panels established to hear the complaints against the retaliation for the Section 232 measures, they have done something interesting that I've never seen before: All the cases have the same chairperson, but then each has different panel members.
William Ehlers of Uruguay is the chair of all the panels, but then the following are panelists on individual cases: DS566 - Petina Gappah and Syed Tauqir Hussain Shah; DS560 - César Montaño Huerta and Fabián Villaroel Ríos; DS559 - Olga Lucía Lozano Ferro and Anwar Zaheer Jamali; DS558 - Cristian Espinosa Cañizares and Mónica Rolong; DS557 - Darlington Mwape and Claudia Uribe.
The facts of each of these cases are a little different (because the measures are different), but the legal issues will be very similar. Will there be any divergence among these various panel members in how they would like to approach the legal reasoning? Will the chair be able to keep them all on the same page? Will there be some juicy dissents?
