Questione giuridica chiave
Whether the federal appeal was sufficiently reasoned under Art. 42 and 106 LTF
Decisione estratta
No. The appellant failed to address an independent ground of the cantonal decision and therefore did not show any violation of law.
Motivazione estratta
Where a decision rests on independent sufficient reasons, all must be challenged. The appellant did not contest the cantonal court's alternative reasoning that his own admissions made the refusal to hear the witness non-arbitrary.
