Kernrechtsfrage
Whether a second exchange of written submissions should be ordered
Extrahierter Entscheid
No second exchange was necessary because the court found no new or unexpected arguments requiring a further response to protect the right to be heard.
Extrahierte Begründung
The appellant did not substantiate the request, and the observations filed by the arbitrator and the respondent did not contain elements justifying a further round of pleadings.
