Kernrechtsfrage
Whether the defendant validly assumed the German company's brokerage debt under Art. 176 OR.
Extrahierter Entscheid
No assumption of debt was proven, neither expressly nor by conduct.
Extrahierte Begründung
The lower court could reject the asserted invoicing practice and payment conduct as insufficient to show a clear offer to replace the debtor; partial payments and ambiguous correspondence did not objectively manifest an intention to become the new debtor.
