Questione giuridica chiave
Whether the federal appeal against the cantonal remittal decision was admissible.
Decisione estratta
The appeal was inadmissible because the challenged decision was incidental and the appellant failed to show the statutory conditions for immediate review.
Motivazione estratta
The cantonal decision was neither final nor a separate competence decision; as an incidental ruling under Art. 93 LTF, admissibility had to be specifically demonstrated, which was not done.
