Questione giuridica chiave
Whether the cantonal appeal court had to reopen the evidence and re-examine the facts in full
Decisione estratta
No. Canton Fribourg law did not require a full retrial; the appellate court could rely on the first-instance file and refuse further evidence absent arbitrariness.
Motivazione estratta
A canton may regulate appellate review; new evidence is not automatic. The appellant merely demanded a complete reprise and did not show that the refusal of evidence was arbitrary or that the proposed evidence was relevant.
