Questione giuridica chiave
Whether the appeal to the Federal Supreme Court was admissible against the cantonal remand judgment.
Decisione estratta
The cantonal judgment was neither a final decision nor a partial decision; as a remand decision on a preliminary issue it was an interlocutory decision challengeable only under Art. 93 BGG, and those conditions were not shown.
Motivazione estratta
The judgment did not finally decide the amount or existence of the disputed water connection fee. The appellants did not demonstrate a non-reparable harm or the saving of extensive evidence proceedings.
