Questão jurídica principal
Whether the federal appeal was admissible despite the appellant's failure to properly challenge the cantonal reasoning and his request to supplement the brief out of time.
Decisão extraída
The appeal was inadmissible because the appellant did not meet the statutory motivation requirements and an extension/supplementation after the appeal deadline was excluded.
Fundamentação extraída
The filing could not be completed after the legal deadline; the appellant merely complained about the refusal of a six-month concordat stay and did not address the cantonal reasons or show manifestly incorrect factual findings.
