Kernrechtsfrage
Whether the reform appeal was admissible despite seeking only annulment and remand.
Extrahierter Entscheid
Yes, only insofar as the alleged violation of inquisitorial duties could require remand; otherwise annulment alone was insufficient.
Extrahierte Begründung
A reform appeal normally must seek modification on the merits, but an exception exists where the federal court would need to remand for further evidence.
