Questione giuridica chiave
Whether the complaint against the finding of acting in a gang was admissible and well founded
Decisione estratta
The challenge was inadmissible insofar as it attacked the facts rather than federal law; in any event, the gang concept was not misapplied.
Motivazione estratta
In a nullity appeal, the Federal Court is bound by the cantonal findings of fact. The appellant merely disputed the factual basis of the organized group activity.
