Kernrechtsfrage
Whether the cantonal court committed a formal denial of justice by declining to decide the respondent's standing to request the permit and start the works without the appellant's consent.
Extrahierter Entscheid
No. The administrative court could limit itself to the object of the dispute, and the appellant did not show that the complementary permit itself required her consent.
Extrahierte Begründung
Private-law questions are generally for the civil courts, but an administrative judge may decide incidental private-law issues only insofar as necessary for the administrative decision. The question whether the respondent could undertake the authorized works exceeded the dispute; the challenge concerned only the complementary permit.
