Questão jurídica principal
Whether the public-law appeal against the municipal regulation was admissible despite being filed before cantonal approval
Decisão extraída
The premature filing did not make the appeal inadmissible; it could be suspended until the constitutive cantonal approval was issued, and no separate challenge to that approval was required.
Fundamentação extraída
Cantonal approval was only a validity condition, not a separate cantonal remedy. The appellant also had sufficient legal interest and the targeted norm was not subject to ordinary cantonal review at the relevant time.
