Questão jurídica principal
Whether the plaintiff's request to declare the defendant's appeal null for lack of a formal statement of appeal was admissible and well-founded.
Decisão extraída
The request was inadmissible because it relied on cantonal procedural law, which cannot be reviewed in reform appeal.
Fundamentação extraída
The Federal Court may review only federal law; procedural complaints based on Ticino law fall outside the reform appeal.
