Question juridique clé
Whether refusing production of a separate file concerning witness Z. violated the right to be heard.
Solution extraite
No. The requested evidence could not change the assessment, given that the court already knew of Z.'s drug addiction and the appellant failed to show any additional relevant fact the file could establish.
Motifs extraits
A court may refuse evidence that is irrelevant or incapable of affecting the outcome; the cantonal court assessed Z.'s credibility with knowledge of his drug use and the separate investigation would not have altered that assessment.
