Kernrechtsfrage
Whether the plaintiff could recover a payment made under execution as a non-debt payment under Art. 86 SchKG.
Extrahierter Entscheid
Yes. The defendant lacked active standing to enforce the assigned claim, and the plaintiff paid under the pressure of enforcement; restitution was therefore available.
Extrahierte Begründung
Art. 86 SchKG allows recovery of a non-debt payment made under execution pressure. The decisive point is the existence of a non-debt and the causal effect of enforcement, not whether the payer knew of the non-debt or whether payment appeared voluntary.
