Kernrechtsfrage
Whether the cantonal court violated the appellant's right to be heard by refusing requested document production.
Extrahierter Entscheid
No violation: the court could refuse the evidence after an anticipatory assessment because the requested documents were not decisive for legality of the permits.
Extrahierte Begründung
The court already had sufficient evidence; the motives for placing the installations on the roof did not determine compliance with the construction rules.
