Questione giuridica chiave
Whether the municipal interpretation of 'indispensable' for business parking permits was lawful and arbitrary
Decisione estratta
The restrictive interpretation was permissible and not arbitrary; it concretized the existing rule rather than unlawfully changing it.
Motivazione estratta
The term 'indispensable' is an indeterminate legal concept allowing discretion. The municipality could tighten a previously overly generous practice to pursue public interests in traffic reduction, urban quality, and air protection, and the private interest of the lawyers did not outweigh that interest.
