Kernrechtsfrage
Whether the City of Zurich had standing to file a constitutional complaint against the cost order.
Extrahierter Entscheid
The city could complain only to the extent it alleged a violation of municipal autonomy; it was acting as a public authority, not as a private party.
Extrahierte Begründung
A public body normally lacks standing in constitutional complaints against other state organs unless it invokes autonomy or a similar protected status, or acts like a private person. Here the city was involved as a hoheitlicher actor in a building-permit dispute.
