Key legal question
Whether the neighboring landowners had standing to bring a constitutional complaint against the building permit decision.
Extracted holding
The complainants were not personally affected in legally protected interests; they relied only on general compliance with building law, so they lacked standing.
Extracted reasoning
Neighbor standing exists only where the invoked rules also protect neighbors. The complainants did not show that the allegedly ignored water-engineering comments affected their own legally protected interests under the cited cantonal provisions; the alleged unlawfulness of a parking area was not the subject matter of the case.
