Kernrechtsfrage
Whether the cantonal remand judgment was a final decision or an incidental decision appealable immediately by reform appeal.
Extrahierter Entscheid
The remand judgment was an incidental decision, not a final or partial decision.
Extrahierte Begründung
The cantonal court did not terminate the proceedings and sent the whole case back for a new decision; such a remand is incidental even if it definitively settles a preliminary question.
