Kernrechtsfrage
Whether the appeal against the renewed deadline for an already final cost advance was admissible
Extrahierter Entscheid
The appeal could not be heard because the cost-advance order had already become final; the new decision only set a fresh deadline for an already binding order, so the matter was res judicata.
Extrahierte Begründung
Only a new deadline for payment of an already final cost advance was at issue. The appellant did not challenge the length of the deadline as such, and the matter had already been finally decided in prior proceedings.
