Questione giuridica chiave
Whether the amended PPE rules unlawfully blocked the appellant from opening a daycare in its exclusive lots.
Decisione estratta
The amendment did not gravely restrict the appellant's exclusive use rights; a double majority was sufficient.
Motivazione estratta
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.
