Questione giuridica chiave
Whether the cantonal court's remand decision was a reviewable final decision or an interim decision causing irreparable harm.
Decisione estratta
The remand decision was treated as an interim decision; irreparable harm was not established.
Motivazione estratta
A new award could still result in the same winner, and the municipality might even re-tender on a different basis, so the appeal was admissible only under the rules for interim decisions, which were not decisive here.
