Kernrechtsfrage
Whether the federal complaint had a proper object after the lower authority decision and the revocation of the challenged attachment order.
Extrahierter Entscheid
The complaint could only be directed against the cantonal appellate supervisory decision; to the extent it targeted a complaint referred back for decision, there was no final cantonal decision to review.
Extrahierte Begründung
Under Art. 19 SchKG, only the decision of the upper supervisory authority is challengeable. No reviewable final decision existed regarding the complaint that had been forwarded to the lower authority.
