Key legal question
Whether the dispute could extend to earlier building permits and require an ordinary building-permit procedure for later works.
Extracted holding
The dispute was properly confined to immission-related questions concerning already final building permissions; the request to compel an ordinary building-permit procedure was outside the scope and inadmissible.
Extracted reasoning
The earlier permits were final. The neighbors had not clearly requested a new ordinary building procedure in the municipal proceedings, so the cantonal court could restrict review to odor and noise emissions.
