Question juridique clé
Whether the federal appeal met the formal reasoning requirements of Art. 42 LTF.
Solution extraite
The appeal did not satisfy the requirements because it contained no formal conclusions and only vague criticism of the cantonal judgment.
Motifs extraits
Art. 42 para. 1 and 2 LTF require concise statements of conclusions, reasons, and evidence showing why the challenged decision violates the law; the appellant merely disputed the factual findings without sufficient legal criticism.
