Kernrechtsfrage
Whether the cantonal court's limited review under Geneva procedural law violated federal law and Art. 110 LTF.
Extrahierter Entscheid
The limitation concerned review of expediency, not free review of facts and law, so it did not conflict with Art. 110 LTF in planning matters.
Extrahierte Begründung
Free review under Art. 110 LTF is narrower than expediency review; the cantonal court in fact examined the federal-law issues and balanced interests freely.
