Questione giuridica chiave
Whether the federal public-law appeal was admissible against the cantonal procedural order excluding the appellants from the proceedings
Decisione estratta
For the affected appellants, the order was equivalent to a final decision because it terminated their participation in the cantonal proceedings.
Motivazione estratta
Although formally procedural, the order definitively ended the appellants' procedural standing; it was therefore reviewable like a final decision under the Federal Supreme Court Act.
