Kernrechtsfrage
Whether the federal complaint could challenge the first-instance decision and the later auction itself.
Extrahierter Entscheid
Only the challenged decision of the higher supervisory authority and the renewed auction date were within the scope of review; attacks on the first-instance ruling and the later auction were not admissible.
Extrahierte Begründung
Under Art. 19 SchKG, the appeal targets only the upper supervisory authority's decision; the later auction was not the subject of the complaint.
