Kernrechtsfrage
Whether the payment order in bill-of-exchange execution was null because it was issued and served by a locally incompetent enforcement office.
Extrahierter Entscheid
Yes. Because the debtor was domiciled in Solothurn and service should have been made through the Solothurn office, the payment order, including the embedded bankruptcy warning, was void.
Extrahierte Begründung
In bill-of-exchange execution the payment order already contains the bankruptcy warning. A service by the locally incompetent office is therefore not merely an appealable defect but a nullity that must be considered ex officio.
