Question juridique clé
Whether the refusal to hear the school director violated the right to be heard.
Solution extraite
No. The proposed testimony was not relevant in light of the cantonal court's anticipatory assessment of evidence.
Motifs extraits
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.
