Kernrechtsfrage
Whether the appeal against the building decision was filed within time despite the disputed service date.
Extrahierter Entscheid
The time limit began with the first delivery on 17 November 2005; the appeal lodged on 5 January 2006 was late.
Extrahierte Begründung
An objectively defective service does not matter if it achieved its purpose. The lawyer had actual knowledge of the decision and could have taken the necessary steps; he could not delay the start of the appeal period at will.
