Kernrechtsfrage
Whether the appeal against the cost-advance order was admissible as an appeal against an interim decision.
Extrahierter Entscheid
The challenged order was an independently appealable interim decision; admissibility was left open because the appeal failed on the merits.
Extrahierte Begründung
A cost-advance order may cause irreparable legal harm where non-payment can lead to non-entry, but the court did not need to decide the point definitively given the outcome.
