Questione giuridica chiave
Whether the federal court could review complaints directed against the lower cantonal supervisory authority and constitutional/ECHR arguments in this debt-enforcement appeal.
Decisione estratta
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.
Motivazione estratta
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.
