Questione giuridica chiave
Whether the refusal to hear proposed witnesses violated the right to be heard and fair trial guarantees.
Decisione estratta
The complaint was not sufficiently substantiated because it did not explain what facts the witnesses would testify to, and the court could also rely on anticipatory assessment of evidence.
Motivazione estratta
A constitutional complaint must identify how the contested decision violates constitutional or convention rights. Moreover, a court may close evidence when further evidence would not alter the already formed, non-arbitrary conviction.
