Questione giuridica chiave
Whether the cantonal court violated municipal autonomy by substituting its own view of the contribution-calculation parameters.
Decisione estratta
Yes. The cantonal court overstepped by treating the municipality’s parameters as unlawful rather than reviewing only constitutionality and legality within the municipality’s discretion.
Motivazione estratta
The municipality had broad autonomy in applying the cantonal improvement-contribution law. The cantonal court could not impose its own calculation scheme merely because it found some factors debatable.
