Questione giuridica chiave
Whether refusing requested letters rogatory violated the right to evidence under Art. 8 CC.
Decisione estratta
No. The cantonal court was entitled to refuse the evidence after an anticipatory assessment showing the requested testimony could not change its conviction.
Motivazione estratta
Art. 8 CC does not prevent anticipatory assessment of evidence; if already available evidence makes the alleged fact unconvincing, further evidence may be refused.
