Kernrechtsfrage
Whether the appeal against the 2004 building permit was filed in time despite defective service to VCS
Extrahierter Entscheid
The appeal period did not remain open until 2007; after visible conversion and a 2005 site visit, VCS had enough indications to inquire and act earlier.
Extrahierte Begründung
Under good faith and legal certainty, a third party not properly notified must act once it has sufficient indications of a relevant decision. Here, the conversion was externally visible and VCS had concrete clues from its prior dealings and the 2005 visit, so waiting until 2007 was too late.
