Question juridique clé
Whether the federal court could review complaints directed against the lower cantonal supervisory authority and constitutional/ECHR arguments in this debt-enforcement appeal.
Solution extraite
Only the decision of the upper cantonal supervisory authority was open to challenge; constitutional and ECHR complaints had to be raised by separate constitutional appeal.
Motifs extraits
In a two-tier cantonal system, Art. 19 SchKG allows review only of the upper supervisory decision. Arguments based on the Federal Constitution or the ECHR are outside this procedure and therefore inadmissible here.
