Questione giuridica chiave
Whether the cantonal ruling on competence was a final decision appealable by civil appeal.
Decisione estratta
No; the cantonal decision was a separate ruling on material competence and therefore not a final decision under Art. 90 LTF, but it could be challenged under the rules for interlocutory decisions.
Motivazione estratta
The appellate authority had remitted the matter to the Chamber of Notaries for a new decision and resolved only the jurisdictional question separately from the merits.
