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