Questione giuridica chiave
Whether refusal to hear the defendant’s sister violated the right to be heard under Art. 29(2) Cst. and cantonal procedure.
Decisione estratta
No violation: the cantonal court could, without arbitrariness, consider the proposed testimony not decisive and not a serious new means of proof.
Motivazione estratta
The sister would only repeat a version already rejected, and the court was entitled to anticipate that her evidence would not change the outcome.
