Questione giuridica chiave
Whether the cantonal remand decision was an incident decision causing irreparable harm and thus challengeable by public law appeal.
Decisione estratta
The remand decision was merely incidental; any disadvantage was only factual and could be challenged later with an appeal against the final decision.
Motivazione estratta
Under Art. 87 OG, incidental decisions are appealable only if they cause irreparable legal harm. A remand to the first instance is in principle a procedural step toward a final decision and does not create such harm, because the party can later raise the same objections against the final judgment.
