Kernrechtsfrage
Whether the ZPO cost-advance rule applies in Zurich state-liability proceedings before the civil courts.
Extrahierter Entscheid
Yes. Applying the federal civil procedure rules as subsidiary cantonal law was not arbitrary.
Extrahierte Begründung
Because state-liability claims are assigned to civil courts, those courts may apply the ZPO unless the canton has enacted a special rule; the ZPO provides a sufficient legal basis for advances.
