Kernrechtsfrage
Whether the cantonal supervisory authority was competent to hear the complaint against the trustee election.
Extrahierter Entscheid
Yes. The canton could provide a single supervisory instance for complaints under Art. 239 SchKG, and the cantonal authority was therefore competent.
Extrahierte Begründung
Art. 13(2) SchKG leaves it to the cantons whether to create additional lower supervisory authorities; Bern validly limited certain complaints to one instance, including the complaint at issue.
