Questione giuridica chiave
Whether the challenge to the negligent unlawful-stay conviction was admissible without motivation
Decisione estratta
The complaint was inadmissible because the appellant provided no reasons addressing that conviction or showing arbitrariness in the cantonal findings.
Motivazione estratta
Federal grounds of appeal must be motivated. The brief addressed only the witness-hearing issue linked to the narcotics conviction and contained no argument against the finding that he knew his stay was illegal.
