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