Questione giuridica chiave
Whether the federal appeal was sufficiently reasoned under Art. 42 BGG
Decisione estratta
No. The appellants did not engage with the cantonal court's decisive reasoning, especially the exclusion of late-filed documents, so the appeal lacked a legally sufficient statement of reasons.
Motivazione estratta
A federal appeal must explain in a concise manner how the challenged decision violates law. The filing merely repeated factual assertions and relied on documents already declared inadmissible, without addressing the procedural point on which the lower court relied.
