Kernrechtsfrage
Whether the appeal was admissible against the partial award on jurisdiction and related findings.
Extrahierter Entscheid
The appeal was admissible only insofar as it challenged the tribunal's competence; insofar as it attacked the merits-like novation finding, it was inadmissible.
Extrahierte Begründung
The challenged ruling on the alleged extinction of rights under contracts A and B was not a jurisdictional ruling but a preliminary merits decision; such a ruling cannot be attacked under the pleaded grounds in this procedural posture.
