Key legal question
Whether the municipal interpretation of 'indispensable' for business parking permits was lawful and arbitrary
Extracted holding
The restrictive interpretation was permissible and not arbitrary; it concretized the existing rule rather than unlawfully changing it.
Extracted reasoning
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.
