Key legal question
Whether the federal complaint against the cantonal supervisory decision was admissible insofar as it sought annulment of earlier decisions.
Extracted holding
The request to annul the lower decisions was inadmissible because only the decision of the upper supervisory authority could be challenged.
Extracted reasoning
Under Art. 19(1) SchKG, the object of the complaint is only the decision of the upper supervisory authority, not prior enforcement or court rulings.
