Kernrechtsfrage
Whether the appellant was entitled to continue the litigation despite not falling under Art. 260 SchKG.
Extrahierter Entscheid
Yes. Even without a cession under Art. 260 SchKG, she could continue the dispute under the principles of Art. 250 SchKG, because a creditor may contest another creditor's admission and the estate had abandoned the defense.
Extrahierte Begründung
The claim had originally been contested by the bankruptcy estate itself. After the estate waived an appeal against the judgment recognizing the claim, the appellant could pursue the abandoned contestation on her own account, with the effects provided by Art. 250 Abs. 3 SchKG.
