Kernrechtsfrage
Whether the complaint could be entertained despite a late request to extend the filing period and a lack of proper reasoning.
Extrahierter Entscheid
No. The filing period under Art. 19(1) SchKG is a forfeiture period, so a belated supplementary submission cannot be considered, and the complaint did not meet the brief reasoning requirements of Art. 79(1) OG.
Extrahierte Begründung
An extension of the complaint period is inadmissible because the period is peremptory. In addition, merely referring to earlier submissions does not satisfy the duty to explain which federal law was violated and how.
