Kernrechtsfrage
Whether the unjust enrichment claim was time-barred under Article 67 CO.
Extrahierter Entscheid
Yes. The one-year limitation period ran at least from 2005-08-02, was not interrupted within one year, and the claim was already prescribed when the second action was filed on 1998-03-23.
Extrahierte Begründung
Notification of the assignment to the debtor was not an opening of action under Article 135 no. 2 CO and therefore had no interruptive effect; the court of appeal had conflated interruption by action with later procedural interruptions under Article 138 CO. Article 139 CO did not apply because the first action had been dismissed on the merits for lack of standing, not for a procedural defect, and no abuse of right barred reliance on prescription.
