Question juridique clé
Whether the cantonal building-permit fee of CHF 13,333.35 violated the equivalence principle, proportionality, equality, or arbitrariness prohibition.
Solution extraite
The reduced fee was not manifestly excessive and remained compatible with the equivalence principle; no unequal treatment or arbitrariness was shown.
Motifs extraits
The tariff allowed a percentage-based fee with a cap and reduction for below-average effort. The project was large, involved several specialist offices, and the fee had already been reduced below the normal 2‰ rate. Given the administrative and coordination effort, the amount was still within reasonable limits.
