Questione giuridica chiave
Whether the refusal to hear the school director violated the right to be heard.
Decisione estratta
No. The proposed testimony was not relevant in light of the cantonal court's anticipatory assessment of evidence.
Motivazione estratta
The appellant did not show, with sufficient reasoning, that she had challenged the factual account on which the cantonal court relied. The court may reject irrelevant evidence, and anticipatory assessment is only reviewable for arbitrariness, which was not properly substantiated.
