Questione giuridica chiave
Whether the federal criminal appeal satisfied the motivation requirements of Art. 42 and 106 LTF.
Decisione estratta
The appeal did not meet the qualified motivation requirements because it merely attacked the merits of the conviction without showing why the cantonal inadmissibility ruling was unlawful.
Motivazione estratta
Where the challenged decision is based on cantonal criminal procedure, the appellant must clearly and precisely show how it violates federal constitutional law; this was not done here.
