Questione giuridica chiave
Whether the complaint could be brought as a voting-rights complaint against the municipal regulation's adoption under facultative rather than mandatory referendum
Decisione estratta
The voting-rights complaint was admissible because the challenge concerned whether the rule should have been adopted at the level of the municipal constitution and submitted to mandatory referendum.
Motivazione estratta
A claim that a legislative act was wrongly subjected to facultative rather than mandatory referendum directly concerns political rights; the distinction applies equally when a council adopts a regulation instead of amending the municipal constitution.
