Kernrechtsfrage
Whether the federal appeal could proceed after the respondent’s death and unclear succession
Extrahierter Entscheid
The file did not establish whether the estate had been accepted or who the heirs were; the case therefore had to be remitted for clarification and further judgment.
Extrahierte Begründung
Under succession and procedural rules, heirs replace the deceased party, but the existence and identity of heirs must be established before the merits can be finally decided. The record was insufficient on these points, which were decisive for the first-instance outcome.
