Key legal question
Whether the debtor could challenge the underlying maintenance claims and their amount in the debt enforcement complaint.
Extracted holding
No. The supervisory complaint cannot be used to review the existence or amount of the enforced claims.
Extracted reasoning
The complaint under Art. 17 SchKG is limited to issues of enforcement law; the debtor did not show that the supervisory authority misunderstood the object of review by refusing to examine the merits of the maintenance debt.
