Kernrechtsfrage
Whether the arbitral tribunal was irregularly constituted because of alleged lack of impartiality of the president and procedural conduct.
Extrahierter Entscheid
No objective appearance of bias was shown; the recusal ground was also raised too late.
Extrahierte Begründung
A provisional view expressed at the hearing did not amount to prejudgment, and alleged procedural mistakes or criticism of the award did not establish partiality.
