Questione giuridica chiave
Whether the appeal was admissible against the partial award on jurisdiction and related findings.
Decisione estratta
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.
Motivazione estratta
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.
