Questione giuridica chiave
Whether the federal appeal met the minimum reasoning requirements.
Decisione estratta
No. The submission did not meaningfully address the cantonal non-entry reasons or show any constitutional or federal-law violation.
Motivazione estratta
Under Art. 42 and 106 BGG, an appeal must engage with the decisive reasoning. The appellant merely discussed the tax assessment and alleged financial difficulties, but did not challenge the legal basis for the missed deadline or any duty to grant an extension.
