Questione giuridica chiave
Whether the federal appeal met the reasoning requirements of Art. 42 LTF
Decisione estratta
No. The filing merely expressed disagreement and alleged a worsening of health, without showing why the cantonal findings were manifestly inaccurate or unlawful.
Motivazione estratta
An appeal must contain conclusions, reasons, and evidence, and explain succinctly how the challenged decision violates law. Mere criticism and factual assertions are insufficient.
