Kernrechtsfrage
Whether the appeal became moot after withdrawal of the building application
Extrahierter Entscheid
Yes. The withdrawal of the building application rendered the appeal moot and the case had to be removed from the docket.
Extrahierte Begründung
The withdrawal eliminated the subject matter of the proceedings, so the court could only strike the appeal as moot under Art. 32(2) BGG, with summary reasoning on costs.
