Kernrechtsfrage
Whether definitive legal opening could be granted for the claimed residual amount based on the foreign judgment and prior payment
Extrahierter Entscheid
No. The creditor did not show a liquid enforceable residual claim based on the title.
Extrahierte Begründung
The court held that under Swiss enforcement law foreign-currency debts are converted into CHF for enforcement, but the conversion does not novate the debt. Whether the debt was already fully satisfied and whether any residual claim remains depends on foreign substantive law, here German law. Because the creditor did not address the decisive issues under that law, the residual claim was not sufficiently liquid for definitive legal opening.
