Kernrechtsfrage
Whether the arbitral tribunal was improperly constituted because the chairperson was biased after surveillance of him and his family.
Extrahierter Entscheid
The chairperson's reaction to the surveillance was objectively appropriate and did not create objectively justified doubts about his independence.
Extrahierte Begründung
The tribunal chair's comments and conduct merely sought to clarify the source and reasons for the surveillance; they contained no personal attack or concrete accusation against either party.
