Key legal question
Whether the supervisory authority had to address the complaint that the bank's acquisition violated its statutory purpose and the debtor's right to housing.
Extracted holding
No. The authority could declare those grievances inadmissible because supervisory bodies may intervene only against acts of the enforcement office and cannot decide substantive disputes between creditor and debtor.
Extracted reasoning
The challenged points concern substantive law, not a measure of the office. The authority therefore acted within its competence by limiting itself to the relevant facts and refusing to examine the merits further.
