Kernrechtsfrage
Whether the cantonal supervisory authority violated its duty to investigate the decisive facts ex officio.
Extrahierter Entscheid
Yes. The authority should have obtained the full file, including the payment order, to determine the amount in enforcement, but remittal was unnecessary because the document was filed before the Federal Court.
Extrahierte Begründung
In debt-enforcement supervisory proceedings the authority must clarify the facts on its own motion and may not wait for party requests. Missing decisive documents must be obtained from the enforcement office.
