Questione giuridica chiave
Whether the federal appeal met the formal requirements of Art. 42 LTF
Decisione estratta
It did not, because the appellant failed to state conclusions and failed to engage with the reasons of the cantonal judgment.
Motivazione estratta
The submission merely alleged a worsening of health but did not explain why the cantonal findings or legal assessment were wrong, so it did not show a violation of federal law as required.
