Questione giuridica chiave
Whether the refusal to take additional evidence violated the right to be heard.
Decisione estratta
The refusal was lawful because the cantonal judge could, after anticipatory assessment of the file, conclude that further evidence would not change the outcome.
Motivazione estratta
The file, including police interrogation records and the train driver’s testimony, already allowed a reliable assessment of the facts. The right to be heard does not require pointless evidence-taking.
