Kernrechtsfrage
Whether the appeal could rely on an alleged debt assumption and lack of identity between debtor and pursued party
Extrahierter Entscheid
Those arguments were inadmissible in reform proceedings because they depended on facts not retained by the cantonal court.
Extrahierte Begründung
The Federal Court is bound by the cantonal findings unless a statutory exception applies; the appellant relied on excluded documents and impermissibly challenged the facts.
