Key legal question
Whether the creditor could challenge for the first time before the Federal Court the fee for issuing the payment order.
Extracted holding
The new challenge was inadmissible because it expanded the scope of the dispute beyond what had been contested below.
Extracted reasoning
Under Art. 99 BGG, new requests and issues that widen the subject matter of the dispute are not admissible; the fee for issuing the payment order had not been disputed before the cantonal authority.
