Kernrechtsfrage
Whether the appellant had standing to challenge the building permit
Extrahierter Entscheid
The appellant did not make his special legal interest sufficiently plausible and therefore lacked standing.
Extrahierte Begründung
He relied only on an unsubstantiated oral fiduciary agreement and offered no concrete proof despite the issue being contested from the outset; requiring proof at that stage was not unconstitutional.
