Questione giuridica chiave
Whether the public-law appeal alleging arbitrariness in fact-finding was admissible
Decisione estratta
The grievance actually concerned the application of federal tenancy law and the principle of receipt, not a constitutional fact-finding issue; the appeal was therefore not admissible.
Motivazione estratta
The Federal Supreme Court held that the appellant's argument challenged the legal characterization of termination and notification under Art. 257d CO. Such arguments belong in the parallel appeal on the merits, not in a public-law appeal limited to constitutional complaints.
