Kernrechtsfrage
Whether the appeal against the cantonal decision refusing party costs was still justiciable after the main legal-relief dispute changed.
Extrahierter Entscheid
The appeal became moot because the Federal Supreme Court later altered the substantive outcome and sent the cantonal costs issue back for reallocation according to that new outcome.
Extrahierte Begründung
Costs follow the result on the merits. Since the appellant ultimately lost in the main debt-enforcement proceedings, the cantonal court could not be faulted for not awarding it party costs; the challenged cost issue no longer required a separate merits review.
