Questione giuridica chiave
Whether the federal appeal satisfied the requirement to challenge the cantonal judgment with sufficient reasoning.
Decisione estratta
No. The submission did not explain why the cantonal inadmissibility ruling was wrong and instead argued the merits of supplementary benefits.
Motivazione estratta
Under Art. 42 LTF, the appeal must briefly show how the challenged decision violates the law. A mere discussion of substantive entitlement, without addressing the timeliness ruling, is insufficient.
