Questione giuridica chiave
Whether the federal appeal met the formal requirements of Art. 42 LTF
Decisione estratta
No; the appeal lacked proper conclusions and did not explain, even briefly, why the cantonal inadmissibility ruling violated the law.
Motivazione estratta
Under Art. 42(1)-(2) LTF, an appeal must state conclusions, reasons, and evidence; arguments addressing the merits do not cure a challenge directed against an inadmissibility ruling.
