Questione giuridica chiave
Whether the federal appeal was admissible despite lacking specific criticism of the lower court's inadmissibility ruling.
Decisione estratta
No. The appeal did not address the reasons for inadmissibility and therefore lacked the required topically reasoned challenge.
Motivazione estratta
Under Art. 42 LTF, the appellant must explain why the contested decision violates federal law. Here he only disputed the tax merits and did not confront the language and motivation defects found by the cantonal court.
