Questione giuridica chiave
Whether the Federal Court could review the cantonal ruling as a jurisdictional interim decision or under denial-of-justice rules.
Decisione estratta
The ruling was an interim decision; Art. 92 BGG did not apply because the cantonal court had not yet decided jurisdiction, and the conditions for an appeal under Art. 93 BGG were not met.
Motivazione estratta
The appellate court only remitted the matter for a decision on jurisdiction and the appellant had already succeeded on the set-aside of two procedural points; no irreparable disadvantage was shown.
