Kernrechtsfrage
Whether the appeal against the interim decision on security for costs was admissible under Art. 93 BGG.
Extrahierter Entscheid
The appeal was admissible because the contested order could cause a non-remediable legal disadvantage if the claimant’s costs claim later proved unrecoverable.
Extrahierte Begründung
Security for costs serves to avoid insolvency risk; such a risk may constitute a legal disadvantage under Art. 93(1)(a) BGG.
