Questione giuridica chiave
Whether the federal appeal was admissible without a final cantonal decision under Art. 75 para. 1 BGG.
Decisione estratta
The appeal was inadmissible because it was not directed against a final cantonal decision; an appeal under Art. 18 SchKG to the upper supervisory authority was still available.
Motivazione estratta
Federal complaint proceedings require a final cantonal decision. The district court acted as lower supervisory authority, and its ruling could still be challenged before the higher supervisory authority, as indicated in the cantonal remedy information.
