Kernrechtsfrage
Whether the federal appeal against the order fixing security for appeal costs was admissible.
Extrahierter Entscheid
The order was an incidental decision; the appellants showed a legal, irreparable prejudice because insufficient security could deprive them of protected cost recovery.
Extrahierte Begründung
A refusal or insufficient amount of security for costs causes a legal injury not cured by a later favorable judgment; therefore Article 93(1)(a) LTF was satisfied.
