Kernrechtsfrage
Whether the appeal against the order requiring an advance on costs was admissible
Extrahierter Entscheid
The complaint was inadmissible because payment of the advance removed any irreparable harm.
Extrahierte Begründung
The challenged order was an interim decision under Art. 93 BGG. Since the advance had been paid in time, the condition of irreparable prejudice had fallen away.
