Key legal question
Whether the claimant may demand a second payment of the assigned CHF 3,530 directly to the social welfare office.
Extracted holding
No. That claim belongs to the assignee social welfare office, not to the claimant; the claimant is not entitled to sue for payment to the assignee.
Extracted reasoning
The assignment transferred the claim to the social welfare office. Since its validity was uncontested, the assignor lacked standing to demand performance to the assignee.
