Key legal question
Whether the complaint against the valuation report and auction notice was filed within the deadline
Extracted holding
The complaint was untimely; the deadline had to be examined ex officio and the postal track-and-trace evidence supported receipt on 1 December 2003.
Extracted reasoning
The deadline for a complaint is peremptory and a condition of admissibility. The office had already contested timeliness, and the debtor neither disproved the postal record nor proved receipt on 2 December 2003.
