Kernrechtsfrage
Whether the amended PPE rules unlawfully blocked the appellant from opening a daycare in its exclusive lots.
Extrahierter Entscheid
The amendment did not gravely restrict the appellant's exclusive use rights; a double majority was sufficient.
Extrahierte Begründung
The lots had never been used for childcare, the building kept its mixed residential/tertiary character, and the restriction only narrowed but did not eliminate tertiary uses.
