Key legal question
Whether refusal to take further evidence violated the right to be heard and a fair trial
Extracted holding
The cantonal court could refuse superfluous evidence because the relevant facts were already established or the proposed evidence was not apt to clarify them.
Extracted reasoning
Anticipatory assessment of evidence is permissible when the fact is irrelevant, already shown by the file, or the evidence is unsuitable; the appellant did not show arbitrariness in the refusal.
