Kernrechtsfrage
Whether the appellant had standing to challenge only the underground floor-area ratio under Art. 59 al. 9 LCI.
Extrahierter Entscheid
He lacked a sufficient practical interest because changing the underground area would not alter the above-ground project or visual impact, and he alleged no special immissions from the underground use.
Extrahierte Begründung
The object of dispute was narrowed to underground surface limits; this rule does not affect the above-ground design. Since the habitable floor area and ground footprint were no longer contested, success would not produce any practical advantage for the neighbor.
