Kernrechtsfrage
Whether the reform appeal could challenge the cantonal judgment after a prior remand by the Federal Supreme Court.
Extrahierter Entscheid
The appeal was inadmissible because the cantonal court had complied with the remand instructions; the parties could not relitigate issues already decided in the remand judgment.
Extrahierte Begründung
Under the binding effect of the remand judgment, the cantonal court had to follow the federal court's legal instructions, and a reform appeal may not reopen questions already decided or not addressed in that prior decision.
