Questione giuridica chiave
Whether the public-law appeal was admissible for a consortium of municipalities challenging the cantonal remittal judgment.
Decisione estratta
The appeal was inadmissible because the consortium, acting as a public-law holder of authority, could not invoke constitutional complaints in this dispute and did not allege a protected municipal autonomy or comparable constitutional interest.
Motivazione estratta
Public-law remedies primarily protect private persons; public bodies may invoke them only in exceptional situations, such as when acting under private law or when municipal autonomy, existence, or territory is at stake. Here the appellant merely contested the internal cost-allocation key and did not substantiate any autonomy claim or other constitutional standing.
