Kernrechtsfrage
Whether the CHF 8 postal fee for service of the payment order was chargeable to the enforcing party.
Extrahierter Entscheid
Yes. The office chose postal delivery service 'Betreibungsurkunde'; that fee could be passed on and did not require a prior unsuccessful delivery attempt.
Extrahierte Begründung
The challenged fee was not the special postal delivery service requiring a failed prior attempt, but the ordinary postal delivery chosen by the office. The cost bill therefore complied with federal debt-enforcement law.
