Questione giuridica chiave
Whether the federal appeal against the first-instance legal-opening order was admissible
Decisione estratta
The appeal was inadmissible insofar as it also targeted the first-instance order, because federal appeal lies only against the last cantonal decision.
Motivazione estratta
Under Art. 75 BGG, only final cantonal decisions may be challenged; the first-instance ruling could therefore not be attacked directly.
