Questão jurídica principal
Whether the federal appeal met the reasoning requirements for admissibility under Art. 42 LTF and could be examined on the merits.
Decisão extraída
The appeal did not explain sufficiently why the cantonal judgment violated federal law or established the facts manifestly incorrectly; it was therefore inadmissible.
Fundamentação extraída
Under Art. 108 LTF, manifestly insufficiently reasoned appeals may be rejected in simplified procedure. The appellant only repeated that he had a standard ski-instructor contract and that the activity was medically recommended, which did not address the cantonal reasoning or the legal requirements of Art. 42 LTF.
