Questão jurídica principal
Whether the communes had standing to challenge the cantonal norm
Decisão extraída
Yes. Municipalities may invoke communal autonomy under Art. 89(2)(c) LTF when they allege an infringement and are affected as public entities.
Fundamentação extraída
It is sufficient that the communes allege a breach of autonomy and are touched in their public-law sphere; actual autonomy and its breach are merits issues.
