Kernrechtsfrage
Whether the public-law appeal against the refusal of seizure was admissible and directed against a final cantonal decision.
Extrahierter Entscheid
The appeal was admissible; the refusal of seizure was not subject to an ordinary cantonal remedy and thus was a final cantonal decision.
Extrahierte Begründung
Geneva procedural law provided no appeal against a refusal to authorize seizure, so the order was rendered by the last cantonal instance.
