Kernrechtsfrage
Whether the constitutional complaint against the debt-enforcement office's service of the payment order was admissible
Extrahierter Entscheid
That criticism was inadmissible because it should have been raised before the supervisory authority over debt-enforcement offices.
Extrahierte Begründung
Challenges to the office's conduct fall under the special supervisory remedy under the Debt Enforcement and Bankruptcy Act, not the public-law appeal.
