Key legal question
Whether the Federal Supreme Court should annul the arbitral award for lack of jurisdiction of the arbitral tribunal.
Extracted holding
The challenge to jurisdiction was out of time because jurisdiction had already been decided in the partial award of 27 May 2007 and could no longer be attacked in this proceeding.
Extracted reasoning
Under Art. 92 BGG, independently notified jurisdiction decisions must be appealed immediately; once challenged and decided, they cannot be attacked again later.
