Kernrechtsfrage
Whether Action patrimoine vivant qualifies as an association of cantonal importance entitled to appeal under LPMNS Art. 63.
Extrahierter Entscheid
Yes. An association with about 850 members drawn from nearly all communes of Geneva and active throughout the canton qualifies as an association of cantonal importance.
Extrahierte Begründung
The statutory notion of cantonal importance must be interpreted systematically and according to its ordinary meaning. A longevity requirement cannot be added by interpretation when LPMNS Art. 63 does not expressly provide one, especially since other statutes mention such a criterion expressly.
