Questione giuridica chiave
Whether the federal public law appeal was admissible against the cantonal remand judgment.
Decisione estratta
The challenged judgment was an incidental remand decision under Art. 93 LTF, and the appellants failed to show irreparable legal prejudice or that an immediate final decision was possible.
Motivazione estratta
A remand order does not end the proceedings. The appellants did not invoke, and the court did not see, any irreparable prejudice; mere delay and added costs are insufficient.
