Key legal question
Whether the complaint procedure under Art. 17 SchKG and a reconsideration request are governed by the cantonal Administrative Procedure Act.
Extracted holding
Yes. In the absence of federal procedural rules on reconsideration, the supervisory authority applied the cantonal law on legal protection in administrative matters; the same approach governs reconsideration requests.
Extracted reasoning
Federal law contains only limited rules on cantonal complaint procedure and no rules on the admissibility of reconsideration. Therefore cantonal procedural law applies, and in Solothurn the Administrative Procedure Act is used by longstanding practice where no special rule exists.
