Questione giuridica chiave
Whether the civil law appeal against the cantonal bankruptcy decision is admissible despite late/insufficient submissions and new evidence.
Decisione estratta
The appeal is inadmissible because the deadline cannot be extended, new evidence is barred, and the appellant did not challenge an independent sufficient ground of the cantonal decision.
Motivazione estratta
The statutory appeal deadline cannot be prolonged; evidence filed for the first time before the Federal Supreme Court is inadmissible; the grounds raised do not meet the substantiation requirements and fail to address one of the two alternative cantonal reasons supporting the bankruptcy confirmation.
