Kernrechtsfrage
Whether the municipality committed an unlawful act under state liability law by causing a purely patrimonial loss.
Extrahierter Entscheid
A mere decrease in market value without damage to the property or restriction of its use is not an immediate infringement of an absolute right and does not by itself establish unlawfulness.
Extrahierte Begründung
The alleged harm was purely economic; the house and land were not damaged and access/use remained intact.
